Cardiovascular disease is treatable with initial treatment primarily focused on diet and lifestyle interventions. Influenza may make heart attacks and strokes more likely and therefore influenza vaccination may decrease the chance of cardiovascular events and death in people with heart disease.

Proper CVD management necessitates a focus on MI and stroke cases due to their combined high mortality rate, keeping in mind the cost-effectiveness of any intervention, especially in developing countries with low or middle income levels. Regarding MI, strategies using aspirin, atenolol, streptokinase or tissue plasminogen activator have been compared for quality-adjusted life-year (QALY) in regions of low and middle income. The costs for a single QALY for aspirin, atenolol, streptokinase, and t-PA were $25, $630–$730, and $16,000, respectively. Aspirin, ACE inhibitors, beta blockers, and statins used together for secondary CVD prevention in the same regions showed single QALY costs of $300–400.

While a healthy diet is beneficial, the effect of antioxidant supplementation (vitamin E, vitamin C, etc.) or vitamins has not been shown to protect against cardiovascular disease and in some cases may possibly result in harm. Mineral supplements have also not been found to be useful. Niacin, a type of vitamin B3, may be an exception with a modest decrease in the risk of cardiovascular events in those at high risk. Magnesium supplementation lowers high blood pressure in a dose dependent manner. Magnesium therapy is recommended for people with ventricular arrhythmia associated with torsades de pointes who present with long QT syndrome as well as for the treatment of people with digoxin intoxication-induced arrhythmias. There is no evidence to support omega-3 fatty acid supplementation.

There is no evidence that any treatment for hangovers is very effective.

- Rehydration: Drinking water before going to bed or during hangover may relieve dehydration-associated symptoms such as thirst, dizziness, dry mouth, and headache.

- Non-steroidal anti-inflammatory drugs such as aspirin or ibuprofen have been proposed as a treatment for the headaches associated with a hangover. There however is no evidence to support a benefit, and there are concerns that taking alcohol and aspirin together may increase the risk of stomach bleeding and liver damage.

- Tolfenamic acid, an inhibitor of prostaglandin synthesis, in a 1983 study reduced headache, nausea, vomiting, irritation but had no effect on tiredness in 30 people.

- Pyritinol: A 1973 study found that large doses (several hundred times the recommended daily intake) of Pyritinol, a synthetic Vitamin B6 analog, can help to reduce hangover symptoms. Possible side effects of pyritinol include hepatitis (liver damage) due to cholestasis and acute pancreatitis.

- Yeast-based extracts: The difference in the change for discomfort, restlessness, and impatience were statistically significant but no significant differences on blood chemistry parameters, blood alcohol or acetaldehyde concentrations have been found, and it did not significantly improve general well-being.

Acute alcohol poisoning is a medical emergency due to the risk of death from respiratory depression and/or inhalation of vomit if emesis occurs while the patient is unconscious and unresponsive. Emergency treatment for acute alcohol poisoning strives to stabilize the patient and maintain a patent airway and respiration, while waiting for the alcohol to metabolize. This can be done by removal of any vomitus or, if patient is unconscious or has impaired gag reflex, intubation of the trachea using an endotracheal tube to maintain adequate airway:

Also:

- Treat hypoglycaemia (low blood sugar) with 50 ml of 50% dextrose solution and saline flush, as ethanol induced hypoglycaemia is unresponsive to glucagon.

- Administer the vitamin thiamine to prevent Wernicke-Korsakoff syndrome, which can cause a seizure (more usually a treatment for chronic alcoholism, but in the acute context usually co-administered to ensure maximal benefit).

- Apply hemodialysis if the blood concentration is dangerously high (>400 mg/dL), and especially if there is metabolic acidosis.

- Provide oxygen therapy as needed via nasal cannula or non-rebreather mask.

- Provide parenteral Metadoxine.

Additional medication may be indicated for treatment of nausea, tremor, and anxiety.

Recommendations for foods, drinks and activities to relieve hangover symptoms abound. The ancient Romans, on the authority of Pliny the Elder, favored raw owl's eggs or fried canary, while the "prairie oyster" restorative, introduced at the 1878 Paris World Exposition, calls for raw egg yolk mixed with Worcestershire sauce, Tabasco sauce, salt and pepper. By 1938, the Ritz-Carlton Hotel provided a hangover remedy in the form of a mixture of Coca-Cola and milk (Coca-Cola itself having been invented, by some accounts, as a hangover remedy). Alcoholic writer Ernest Hemingway relied on tomato juice and beer. Other purported hangover cures include cocktails such as Bloody Mary or Black Velvet (consisting of equal parts champagne and stout). A 1957 survey by an American folklorist found widespread belief in the efficacy of heavy fried foods, tomato juice and sexual activity.

Other untested or discredited treatments include:

- Hair of the dog: The belief is that consumption of further alcohol after the onset of a hangover will relieve symptoms, based upon the theory that the hangover represents a form of alcohol withdrawal and that by satiating the body's need for alcohol the symptoms will be relieved. Social drinkers and alcoholics claim that drinking more alcohol gives relief from hangover symptoms, but research shows that the use of alcohol as a hangover cure seems to predict current or future problem drinking and alcohol use disorder, through negative reinforcement and the development of physical dependence. While the practice is popular in tradition and promoted by many sellers of alcoholic beverages, medical opinion holds that the practice merely postpones the symptoms, and courts addiction. Favored choices include Fernet Branca and Bloody Mary.

- Kudzu ("Pueraria montana var. lobata"): The main ingredient in remedies such as kakkonto. A study concluded, "The chronic usage of "Pueraria lobata" at times of high ethanol consumption, such as in hangover remedies, may predispose subjects to an increased risk of acetaldehyde-related neoplasm and pathology. ... Pueraria lobata appears to be an inappropriate herb for use in herbal hangover remedies as it is an inhibitor of ALDH2."

- Artichoke: Research shows that artichoke extract does not prevent the signs and symptoms of alcohol-induced hangover.

- Sauna or steam-bath: Medical opinion holds this may be dangerous, as the combination of alcohol and hyperthermia increases the likelihood of dangerous cardiac arrhythmias.

- Oxygen: There have been anecdotal reports from those with easy access to a breathing oxygen supply – medical staff, and military pilots — that oxygen can also reduce the symptoms of hangovers sometimes caused by alcohol consumption. The theory is that the increased oxygen flow resulting from oxygen therapy improves the metabolic rate, and thus increases the speed at which toxins are broken down. However, one source states that (in an aviation context) oxygen has no effect on physical impairment caused by hangover.

- Fructose and glucose: Glucose and fructose significantly inhibit the metabolic changes produced by alcohol intoxication, nevertheless they have no significant effect on hangover severity.

- Vitamin B: No effects on alcohol metabolism, peak blood alcohol and glucose concentrations have been found and psychomotor function is not significantly improved when using Vitamin B supplements.

- Caffeinated drinks: No significant correlation between caffeine use and hangover severity has been found.

Youth treatment and intervention should focus on eliminating or reducing the effects of adverse childhood experiences, like childhood maltreatment, since these are common risk factors contributing to the early development of alcohol abuse. Approaches like contingency management and motivational interviewing have shown to be effective means of treating substance abuse in impulsive adolescents by focusing on positive rewards and redirecting them towards healthier goals. Educating youth about what is considered heavy drinking along with helping them focus on their own drinking behaviors has been shown to effectively change their perceptions of drinking and could potentially help them to avoid alcohol abuse.

Completely stopping the use of alcohol, or "abstinence," is the ideal goal of treatment. A strong social network and family support maybe important in achieving this goal.

Some people who abuse alcohol may be able to reduce the amount they drink, also called "drinking in moderation." If this method does not work, the person may need to try abstinence. Abstinence has been regularly achieved by many alcoholics in Alcoholics Anonymous.

Mindfulness-based intervention programs (that encourage people to be aware of their own experiences in the present moment and of emotions that arise from thoughts) can reduce the consumption of alcohol.

A normal liver detoxifies the blood of alcohol over a period of time that depends on the initial level and the patient's overall physical condition. An abnormal liver will take longer but still succeeds, provided the alcohol does not cause liver failure.

People having drunk heavily for several days or weeks may have withdrawal symptoms after the acute intoxication has subsided.

A person consuming a dangerous amount of alcohol persistently can develop memory blackouts and idiosyncratic intoxication or pathological drunkenness symptoms.

Long-term persistent consumption of excessive amounts of alcohol can cause liver damage and have other deleterious health effects.

Recent research suggests that sulfur amino acids have a protective effect against the toxicity of ODAP.

Eating the chickling pea with grain having high concentrations of sulphur-based amino acids reduces the risk of lathyrism if grain is available. Food preparation is also an important factor. Toxic amino acids are readily soluble in water and can be leached. Bacterial (lactic acid) and fungal (tempeh) fermentation is useful to reduce ODAP content. Moist heat (boiling, steaming) denatures protease inhibitors which otherwise add to the toxic effect of raw grasspea through depletion of protective sulfur amino acids. During times of drought and famine, water for steeping and fuel for boiling is frequently also in short supply. Poor people sometimes know how to reduce the chance of developing lathyrism but face a choice between risking lathyrism or starvation.

The underlying cause for excessive consumption of grasspea is a lack of alternative food sources. This is a consequence of poverty and political conflict. The prevention of lathyrism is therefore a socio-economic challenge.

To best manage symptoms, refraining from consuming alcohol is essential. Abstinence from alcohol encourages proper diet and helps prevent progression or recurrence of the neuropathy. Once an individual stops consuming alcohol it is important to make sure they understand that substantial recovery usually isn't seen for a few months. Some subjective improvement may appear right away, but this is usually due to the overall benefits of alcohol detoxification. If alcohol consumption continues, vitamin supplementation alone is not enough to improve the symptoms of most individuals.

Nutritional therapy with parenteral multivitamins is beneficial to implement until the person can maintain adequate nutritional intake. Treatments also include vitamin supplementation (especially thiamine). In more severe cases of nutritional deficiency 320 mg/day of benfotiamine for 4 weeks followed by 120 mg/day for 4 more weeks may be prescribed in an effort to return thiamine levels to normal.

Painful dysesthesias caused by alcoholic polyneuropathy can be treated by using gabapentin or amitriptyline in combination with over-the-counter pain medications, such as aspirin, ibuprofen, or acetaminophen. Tricyclic antidepressants such as amitriptyline, or carbamazepine may help stabbing pains and have central and peripheral anticholinergic and sedative effects. These agents have central effects on pain transmission and block the active reuptake of norepinephrine and serotonin.

Anticonvulsant drugs like gabapentin block the active reuptake of norepinephrine and serotonin and have properties that relieve neuropathic pain. However, these drugs take a few weeks to become effective and are rarely used in the treatment of acute pain.

Topical analgesics like capsaicin may also relieve minor aches and pains of muscles and joints.

Brainerd diarrhea is a sudden-onset watery, explosive diarrhea that lasts for months and does not respond to antibiotics; the cause of Brainerd diarrhea is unknown. Brainerd diarrhea was first described in Brainerd, Minnesota in 1983.

It has been associated with the consumption of raw milk and untreated water. Of the ten outbreaks reported since 1983, nine have been in the U.S. The characteristics of each outbreak have been similar to that caused by an infectious agent. Although a comparatively large outbreak (117 patients) occurred in 1996 in Fannin County, Texas., the largest outbreak (122 patients) was the original one in Brainerd, MN. There have been no secondary cases reported in any of the outbreaks, suggesting that the

causative agent cannot be passed from person to person, but boiling water appears to inactivate the Brainerd agent. Although there is no treatment available, the disease does appear to resolve itself, although this process takes months if not years.

Preventing or reducing the harm has been called for via increased taxation of alcohol, stricter regulation of alcohol advertising and the provision of brief Interventions. Brief Interventions for alcohol abuse reduce the incidence of unsafe sex, sexual violence, unplanned pregnancy and, likely, STD transmission. Information and education on social norms and the harms associated with alcohol abuse delivered via the internet or face-to-face has not been found to result in any meaningful benefit in changing harmful drinking behaviours in young people.

According to European law, individuals who are suffering from alcohol abuse or other related problems cannot be given a license, or if in possession of a license cannot get it renewed. This is a way to prevent individuals driving under the influence of alcohol, but does not prevent alcohol abuse per se.

An individual's need for alcohol can depend on their family's alcohol use history. For instance, if it is discovered that their family history with alcohol has a strong pattern, there might be a need for education to be set in place to reduce the likelihood of reoccurrence (Powers, 2007). However, studies have established that those with alcohol abuse tend to have family members who try to provide help. In many of these occasions the family members would try to help the individual to change or to help improve the individual's lifestyle.

Meth mouth is very difficult to treat unless the patient stops using methamphetamine; persistent drug use makes changes in hygiene or nutrition practices unlikely. Many drug users lack access to dental treatment, and few are willing to participate in such a course of action, often because of poverty. Those who are willing to seek dental treatment often resist discussing their drug use. Providing dental treatment to individuals who use methamphetamine can also be dangerous, because the potential combination of local anesthetic and methamphetamine can cause serious heart problems. There is also an increased risk of serious side effects if opioid medications are used in the patient's treatment.

Treatment of meth mouth usually attempts to increase salivary flow, halt tooth decay, and encourage behavioral changes. Toothpaste with fluoride is very important to the restoration of dental health. Only prescription fluoride rinses can adequately treat the condition. Sialogogues, drugs that increase the amount of saliva in the mouth, can be used to treat dry mouth and protect against dental health problems. Pilocarpine and cevimeline are sialogogues approved by the Food and Drug Administration (FDA) to treat low salivation caused by Sjogren's syndrome and may have the potential to effectively treat dry mouth caused by methamphetamine use.

Education about oral hygiene for long-term methamphetamine users is sometimes required. Changes in diet are often necessary for recovering drug users that are receiving dental treatment, and the use of sugar-free gum may be beneficial. The consumption of water and the avoidance of beverages with a diuretic (dehydrating) effect can also help patients with meth mouth.

Generally, PLE resolves without treatment; also, PLE irritations generally leave no scar. However, in severe cases the use of steroids is necessary to help reduce inflammation and increase quality of life of the patient. There are also other therapies for patients who are severely impacted, such as light therapy to harden the skin's surface.

Compulsive overeating is treatable with nutritional assistance and medication. Psychotherapy may also be required, but recent research has proven this to be useful only as a complementary resource, with short-term effectiveness in middle to severe cases.

Lisdexamfetamine is an FDA-approved appetite suppressant drug that is indicated for the treatment of binge eating disorder. The antidepressant fluoxetine is a medication that is approved by the Food and Drug Administration (FDA) for the treatment of an eating disorder, specifically bulimia nervosa. This medication has been prescribed off-label for the treatment of binge eating disorder (BED). Off-label medications, such as other selective serotonin reuptake inhibitors (SSRIs), have shown some efficacy, as have several atypical agents, such as mianserin, trazodone and bupropion. Anti-obesity medications have also proven very effective. Studies suggest that anti-obesity drugs, or moderate appetite suppressants, may be key to controlling binge eating.

Many eating disorders are thought to be behavioral patterns that stem from emotional struggles; for the individual to develop lasting improvement and a healthy relationship with food, these affective obstacles need to be resolved. Individuals can overcome compulsive overeating through treatment, which should include talk therapy and medical and nutritional counseling. Such counseling has been recently sanctioned by the American Dental Association in their journal article cover-story for the first time in history in 2012: Given "the continued increase in obesity in the United States and the willingness of dentists to assist in prevention and interventional effort, experts in obesity intervention in conjunction with dental educators should develop models of intervention within the scope of dental practice". Moreover, dental appliances such as conventional jaw wiring and orthodontic wiring for controlling compulsive overeating have been shown to be “efficient ways in terms of weight control in properly selected obese patients and usually no serious complications could be encountered through the treatment course.

As well, several twelve-step programs exist to help members recover from compulsive overeating and food addiction, such as Overeaters Anonymous and others.

For the worm, humans are a dead-end host. "Anisakis" and "Pseudoterranova" larvae cannot survive in humans, and eventually die. In some cases, the infection resolves with only symptomatic treatment. In other cases, however, infection can lead to small bowel obstruction, which may require surgery, although treatment with albendazole alone (avoiding surgery) has been reported to be successful. Intestinal perforation (an emergency) is also possible.

Sobriety is the condition of not having any measurable levels, or effects from mood-altering drugs. According to WHO "Lexicon of alcohol and drug terms..." sobriety is continued abstinence from psychoactive drug use. Sobriety is also considered to be the natural state of a human being given at a birth. In a treatment setting, sobriety is the achieved goal of independence from consuming or craving mind-altering substances. As such, sustained abstinence is a prerequisite for sobriety. Early in abstinence, residual effects of mind-altering substances can preclude sobriety. These effects are labeled "PAWS", or "post acute withdrawal syndrome". Someone who abstains, but has a latent desire to resume use, is not considered truly sober. An abstainer may be subconsciously motivated to resume drug use, but for a variety of reasons, abstains (e.g. such as a medical or legal concern precluding use). Sobriety has more specific meanings within specific contexts, such as the culture of Alcoholics Anonymous, other 12 step programs, law enforcement, and some schools of psychology. In some cases, sobriety implies achieving "life balance".

As with all cases of hyponatremia, extreme caution must be taken to avoid the fatal consequences of rapidly correcting electrolytes (e.g. Central pontine myelinolysis, edema). Special considerations with the treatment of potomania are needed. Because this could be a chronic condition, low sodium may be normal for the patient, so an especially careful correction is warranted. It is also very important to note that due to the normal kidney function, and lack of other intrinsic or toxic cause of the electrolyte disturbance, restoration of dietary solutes will correct the electrolytes to normal serum levels. This again must be done with caution.

Blood transfusion is sometimes used to treat iron deficiency with hemodynamic instability. Sometimes transfusions are considered for people who have chronic iron deficiency or who will soon go to surgery, but even if such people have low hemoglobin, they should be given oral treatment or intravenous iron.

For individuals prescribed anti-anxiety medications such as Alprazolam (Xanax), caffeine can introduce further problems by increasing rates of cytotoxicity and cell death by necrosis. This leads to these medications being essentially ruled out as viable treatments for caffeine-induced anxiety. Due to caffeine’s negative interaction with anti-anxiety medications such as benzodiazepines, treatments for caffeine-induced anxiety disorder tend to focus on abstinence from or a reduction of caffeine intake and behavioral therapy. Some doctors may recommend a continuance of caffeine consumption but with the provision that the patient actively takes note of physiological changes that happen after caffeine intake. The goal of this approach is to help patients better understand the effects of caffeine on the body and to distinguish threatening symptoms from normal reactions.

Experiments for human toxicology require a long term following and a large amount of investment in order to classify a chemical as co-carcinogens, carcinogens or anti-carcinogenic. In recent years, people substitutes health supplement for healthy meal. Some myths even state beta carotene as elixir in developing country(The Third World).

With rising health consciousness, people rely on food supplements like vitamins A, B, C, D, E etc. these vitamins act as anti-oxidants chemical in the human body. Antioxidants is a good chemical in the appropriate consumption but a large overdose can cause cellular oxidation and cause cytopathic. Also, the industries can not strictly control the concentration and dose for supplement that extracted from natural food resources. A long-term consumption of those supplement can cause physical burden and also a significant hard work for organ to metabolize. Many health organization and government have published a maximum daily consumption for supplement called Tolerable Upper Intake Levels (UL), for example World Health Organization suggest the Tolerable Upper Intake Levels of Vitamin C is 2000 mg/d for adult men from age 31 to 50. Tolerable Upper Intake Levels is different for different gender and age. These suggested intake level can be followed in order to maintain the public health and safety.

Both animal and human experiment research shows that supplement cannot be the substitution to replace the daily food diet. Having a diverse diet and healthy habits is the better way to stay healthy instead of taking a lots of supplement that might be a co-carcinogen.

Different countries recommend different maximum quantities. For most countries, the maximum quantity for men is 140 g–210 g per week. For women, the range is 84 g–140 g per week. Most countries recommend total abstinence during pregnancy and lactation.

The anti-bacterial nature of alcohol has long been associated with soothing stomach irritations and ailments like traveler's diarrhea where it was a preferred treatment to the less palatable bismuth treatments. The risk of infection from the bacterium "Helicobacter pylori", strongly associated with causing gastritis and peptic ulcers as well as being closely linked to stomach cancer, appears to lessen with moderate alcohol consumption. A German study conducted in the late 1990s showed that non-drinkers had slightly higher infection rates of "Helicobacter pylori" than moderate wine and beer drinkers.

Wine's positive effects on the metabolism of cholesterol has been suggested as a link to lower occurrences of gallstones among moderate drinkers since cholesterol is a major component of gallstones.

To relieve reactive hypoglycemia, the NIH recommends taking the following steps:

- Avoiding or limiting sugar intake;

- Exercising regularly; exercise increases sugar uptake which decreases excessive insulin release

- Eating a variety of foods, including meat, poultry, fish, or nonmeat sources of protein, foods such as whole-grains, fruits, nuts, vegetables, and dairy products;

- Choosing high-fiber foods.

Other tips to prevent sugar crashes include:

- Avoiding eating meals or snacks composed entirely of carbohydrates; simultaneously ingest fats and proteins, which have slower rates of absorption.

- Consistently choosing longer lasting, complex carbohydrates to prevent rapid blood-sugar dips in the event that one does consume a disproportionately large amount of carbohydrates with a meal

- Monitoring any effects medication may have on symptoms.

Low-carbohydrate diet and/or frequent small split meals is the first treatment of this condition. The first important point is to add small meals at the middle of the morning and of the afternoon, when glycemia would start to decrease. If adequate composition of the meal is found, the fall in blood glucose is thus prevented. Patients should avoid rapidly absorbable sugars and thus avoid popular soft drinks rich in glucose or sucrose. They should also be cautious with drinks associating sugar and alcohol, mainly in the fasting state.

As it is a short-term ailment, a sugar crash does not usually require medical intervention in most people. The most important factors to consider when addressing this issue are the composition and timing of foods.

Acute low blood sugar symptoms are best treated by consuming small amounts of sweet foods, so as to regain balance in the body’s carbohydrate metabolism. Suggestions include sugary foods that are quickly digested, such as:

- Dried fruit

- Soft drinks

- Juice

- Sugar as sweets, tablets or cubes.

Iron is needed for bacterial growth making its bioavailability an important factor in controlling infection. Blood plasma as a result carries iron tightly bound to transferrin, which is taken up by cells by endocytosing transferrin, thus preventing its access to bacteria. Between 15 and 20 percent of the protein content in human milk consists of lactoferrin that binds iron. As a comparison, in cow's milk, this is only 2 percent. As a result, breast fed babies have fewer infections. Lactoferrin is also concentrated in tears, saliva and at wounds to bind iron to limit bacterial growth. Egg white contains 12% conalbumin to withhold it from bacteria that get through the egg shell (for this reason, prior to antibiotics, egg white was used to treat infections).

To reduce bacterial growth, plasma concentrations of iron are lowered in a variety of systemic inflammatory states due to increased production of hepcidin which is mainly released by the liver in response to increased production of pro-inflammatory cytokines such as Interleukin-6. This functional iron deficiency will resolve once the source of inflammation is rectified; however, if not resolved, it can progress to Anaemia of Chronic Inflammation. The underlying inflammation can be caused by fever, inflammatory bowel disease, infections, Chronic Heart Failure (CHF), carcinomas, or following surgery.

Reflecting this link between iron bioavailability and bacterial growth, the taking of oral iron supplements in excess of 200 mg/day causes a relative overabundance of iron that can alter the types of bacteria that are present within the gut. There have been concerns regarding parenteral iron being administered whilst bacteremia is present, although this has not been borne out in clinical practice. A moderate iron deficiency, in contrast, can provide protection against acute infection, especially against organisms that reside within hepatocytes and macrophages, such as malaria and tuberculosis. This is mainly beneficial in regions with a high prevalence of these diseases and where standard treatment is unavailable.
