Treatment generally consists of rest, followed by a controlled exercise program, based on clinical and ultrasound findings. Many other treatments related to tendon and ligament injuries have been tried. (See tendinitis)

Appropriate treatment for lameness depends on the condition diagnosed, but at a minimum it usually includes rest or decreased activity and anti-inflammatory medications. Other treatment options, such as corrective shoeing, joint injections, and regenerative therapies, are pursued based on the cause of lameness and the financial limits of the owner. Consultation with a veterinarian is generally recommended, even for mild cases, as some types of lameness may worsen if not properly diagnosed and treated.

Plyometrics exercises such as squat jumps and power skipping should not be implemented until the ankle has regained full agility.

Other strategies that can be used to prevent ankle injury include:

- Ensure proper warm-up prior to stretching and activity;

- When running, choose level surfaces and avoid rocks or holes;

- Ensure that shoes have adequate heel support; and...

- If high-heeled shoes are worn, ensure that heels are no more than 2 inches in height, and avoid heels with a narrow base.

Ice is often used to reduce swelling in cycles of 15–20 minutes on and 20–30 minutes off. Icing an ankle too long can cause cold injuries, indicated if the area turns white.

In uncomplicated lateral ankle sprains, swelling of the soft tissue can be prevented with compression around both malleoli, elevation of the injured ankle higher than the heart, and pain-free exercises.

An orthopedic walking boot is often used for the treatment of a sprained ankle injury. Braces and crutches are also used to help alleviate the pain so the injured ankle can heal as quickly and painlessly as possible.

Although found to be less effective than casts, compression bandages are used to provide support and compression for sprained ankles. Wrapping is started at the ball of the foot and slowly continued up to the base of the calf muscle, which pushes the swelling up toward the center of the body so that it does not gather in the foot.

Nerve blocks involve injecting a small amount of local anesthetic around a nerve or into a synovial structure (such as a joint or tendon sheath) in order to block the perception of pain in a specific area. After the substance is injected, it is given a few minutes to take effect. The block is then tested by pushing a blunt object, such as a ballpoint pen, into the area that is supposed to be desensitized. If the horse does not react to this pressure, the area is desensitized, and the horse is trotted to see if the lameness has improved. Improvement indicates that the cause of lameness was from a structure desensitized by the nerve block.

Nerve blocks are performed in a step-wise fashion, beginning at the most distal (lower) part of the limb and moving upward. This is due to the fact that blocking a nerve higher up will desensitize everything it innervates distal to the blocking location. For example, blocking the leg at the level of the fetlock will also block the entire foot, since the nerve fibers that innervate the foot are inhibited when they travel through the fetlock area. A positive result from this block will not be able to differentiate foot pain from pain in the pastern or fetlock region. More information may be gained from blocking the foot first, then the fetlock, since it allows for greater specificity in determining the cause of lameness.

The duration of the anesthetic varies depending on the substance used. Lidocaine is especially short acting, and is therefore usually not used for lameness evaluations. The longer-acting anesthetic mepivacaine is most-commonly used for nerve blocks, because ideally the block should last throughout the lameness exam to avoid false positives with subsequent blocks as they are performed up the leg. Bupivicaine is very long-lasting (up to 4–6 hours), and is most commonly used for analgesia following surgery rather than for nerve blocks.

Although nerve blocks are very important to the lameness examination, they are not foolproof. Multiple studies have shown that the anesthetic can migrate, especially if the horse is evaluated long after blocking or if a large amount of anesthetic is used. If the anesthetic migrates to the structure that is causing the horse pain, the horse will have a positive block, and the examiner will conclude that the lameness originates in an area that is not actually causing the horse discomfort. False results can also be secondary to practitioner error if the anesthetic is accidentally administered into a location that was unintended, such as a synovial structure rather than around a nerve. Additionally, individual horses have variation in their neural anatomy, and if atypical patterns are present, a given block may block an area unintended by the examiner, leading to false positives. Joints present additional problems. A large volume of anesthetic placed into a joint can diffuse out over time, blocking the surrounding structures. Additionally, there are some cases where joint pain can respond better to perineural blocking rather than blocking of the joint.

Curb as a visible blemish is an easy diagnosis, as swelling in the distal lateral hock region is, by definition, curb. However, ultrasound is an essential tool in the diagnosis and in establishing a treatment plan. Diagnostic anesthesia (local or nerve blocks) can be helpful, but is not perfectly specific in this area.

In China, traditional treatment based on the causes suggested by cultural beliefs are administrated to the patient. Praying to gods and asking Taoist priests to perform exorcism is common. If a fox spirit is believed to be involved, people may hit gongs or beat the person to drive it out. The person will receive a yang- or yin-augmenting Chinese medicine potion, usually including herbs, pilose antler (stag of deer) or deer tail, and tiger penis, deer penis, or fur seal penis. Other foods for therapy are pepper soup, ginger soup and liquor.

A good milking routine is vital. This usually consists of applying a pre-milking teat dip or spray, such as an iodine spray, and wiping teats dry prior to milking. The milking machine is then applied. After milking, the teats can be cleaned again to remove any growth medium for bacteria. A post milking product such as iodine-propylene glycol dip is used as a disinfectant and a barrier between the open teat and the bacteria in the air.

Mastitis can occur after milking because the teat holes close after 15 minutes if the animal sits in a dirty place with feces and urine.

Treatment is possible with long-acting antibiotics, but milk from such cows is not marketable until drug residues have left the cow's system. Antibiotics may be systemic (injected into the body), or they may be forced upwards into the teat through the teat canal (intramammary infusion). Cows being treated may be marked with tape to alert dairy workers, and their milk is syphoned off and discarded. To determine whether the levels of antibiotic residuals are within regulatory requirements, special tests exist. Vaccinations for mastitis are available, but as they only reduce the severity of the condition, and cannot prevent reoccurring infections, they should be used in conjunction with a mastitis prevention program.

In historical culture-bound cases, reassurance and talks on sexual anatomy are given. Patients are treated with psychotherapy distributed according to symptoms and to etiologically significant points in the past. Prognosis appears to be better in cases with a previously functional personality, a short history and low frequency of attacks, and a relatively uncomplicated sexual life.

For sporadic Western cases, careful diagnostic workup including searching for underlying sexual conflict is common. The choice of psychotherapeutic treatment is based on the psychiatric pathology found.

In 2001 the American Thoracic Society, drawing on the work of the British and Canadian Thoracic Societies, established guidelines for the management of adult CAP dividing patients into four categories based on common organisms:

- Healthy outpatients without risk factors: This group (the largest) is composed of otherwise-healthy patients without risk factors for DRSP, enteric gram-negative bacteria, "pseudomonas" or other, less-common, causes of CAP. Primary microoganisms are viruses, atypical bacteria, penicillin-sensitive "streptococcus pneumoniae" and "haemophilus influenzae". Recommended drugs are macrolide antibiotics, such as azithromycin or clarithromycin, for seven to ten days.

- Outpatients with underlying illness or risk factors: Although this group does not require hospitalization, patients have underlying health problems (such as emphysema or heart failure) or are at risk for DRSP or enteric gram-negative bacteria. They are treated with a quinolone active against "streptococcus pneumoniae" (such as levofloxacin) or a β-lactam antibiotic (such as cefpodoxime, cefuroxime, amoxicillin or amoxicillin/clavulanic acid) and a macrolide antibiotic, such as azithromycin or clarithromycin, for seven to ten days.

- Hospitalized patients without risk for "pseudomonas": This group requires intravenous antibiotics, with a quinolone active against "streptococcus pneumoniae" (such as levofloxacin), a β-lactam antibiotic (such as cefotaxime, ceftriaxone, ampicillin/sulbactam or high-dose ampicillin plus a macrolide antibiotic (such as azithromycin or clarithromycin) for seven to ten days.

- Intensive-care patients at risk for "pseudomonas aeruginosa": These patients require antibiotics targeting this difficult-to-eradicate bacterium. One regimen is an intravenous antipseudomonal beta-lactam such as cefepime, imipenem, meropenem or piperacillin/tazobactam, plus an IV antipseudomonal fluoroquinolone such as levofloxacin. Another is an IV antipseudomonal beta-lactam such as cefepime, imipenem, meropenem or piperacillin/tazobactam, plus an aminoglycoside such as gentamicin or tobramycin, plus a macrolide (such as azithromycin) or a nonpseudomonal fluoroquinolone such as ciprofloxacin.

For mild-to-moderate CAP, shorter courses of antibiotics (3–7 days) seem to be sufficient.

Some patients with CAP will be at increased risk of death despite antimicrobial treatment. A key reason for this is the host's exaggerated inflammatory response. On one hand it is required to control the infection but on the other, it leads to bystander tissue damage. As a consequence of this recent research focuses on immunomodulatory therapy that can modulate the immune response to reduce injury to the lung and other affected organs such as the heart. Although the evidence for these agents has not resulted in their routine use, there potential benefits are highly promising.

Treatment of CAP in children depends on the child's age and the severity of illness. Children under five are not usually treated for atypical bacteria. If hospitalization is not required, a seven-day course of amoxicillin is often prescribed, with co-trimaxazole an alternative when there is allergy to penicillins. Further studies are needed to confirm the efficacy of newer antibiotics. With the increase in drug-resistant Streptococcus pneumoniae, antibiotics such as cefpodoxime may become more popular. Hospitalized children receive intravenous ampicillin, ceftriaxone or cefotaxime, and a recent study found that a three-day course of antibiotics seems sufficient for most mild-to-moderate CAP in children.

In general, aspiration pneumonitis is treated conservatively with antibiotics indicated only for aspiration pneumonia. The choice of antibiotic will depend on several factors, including the suspected causative organism and whether pneumonia was acquired in the community or developed in a hospital setting. Common options include clindamycin, a combination of a beta-lactam antibiotic and metronidazole, or an aminoglycoside.

Corticosteroids are sometimes used in aspiration pneumonia, but there is limited evidence to support their effectiveness.

Neuraminidase inhibitors may be used to treat viral pneumonia caused by influenza viruses (influenza A and influenza B). No specific antiviral medications are recommended for other types of community acquired viral pneumonias including SARS coronavirus, adenovirus, hantavirus, and parainfluenza virus. Influenza A may be treated with rimantadine or amantadine, while influenza A or B may be treated with oseltamivir, zanamivir or peramivir. These are of most benefit if they are started within 48 hours of the onset of symptoms. Many strains of H5N1 influenza A, also known as avian influenza or "bird flu", have shown resistance to rimantadine and amantadine. The use of antibiotics in viral pneumonia is recommended by some experts, as it is impossible to rule out a complicating bacterial infection. The British Thoracic Society recommends that antibiotics be withheld in those with mild disease. The use of corticosteroids is controversial.

Diagnosis typically is based on physical signs, X-rays, and improvement after treatment.

Obesity in Nauru is a major health concern for the nation. In 2007 Forbes.com reported that, according to the World Health Organization's (WHO) latest estimate, Nauru has the highest percentage of overweight inhabitants among all countries. The estimation identified 94.5% of its residents as overweight. The obesity rate is 71.7%, the highest in the world. The definition of "overweight" and "obesity" are based on body mass index (BMI). People with BMI more than or equal to 25 are classified as overweight, and people with BMI more than or equal to 30 are classified as obese.

The average body weight among Nauruans is estimated to be approximately . Nauru has an average BMI between 34 and 35.

Scurvy can be prevented by a diet that includes vitamin C-rich foods such as bell peppers (sweet peppers), blackcurrants, broccoli, chili peppers, guava, kiwifruit, and parsley. Other sources rich in vitamin C are fruits such as lemons, oranges, papaya, and strawberries. It is also found in vegetables, such as brussels sprouts, cabbage, potatoes, and spinach. Some fruits and vegetables not high in vitamin C may be pickled in lemon juice, which is high in vitamin C. Though redundant in the presence of a balanced diet, various nutritional supplements are available that provide ascorbic acid well in excess of that required to prevent scurvy.

Some animal products, including liver, Muktuk (whale skin), oysters, and parts of the central nervous system, including the adrenal medulla, brain, and spinal cord, contain large amounts of vitamin C, and can even be used to treat scurvy. Fresh meat from animals which make their own vitamin C (which most animals do) contains enough vitamin C to prevent scurvy, and even partly treat it. In some cases (notably French soldiers eating fresh horse meat), it was discovered that meat alone, even partly cooked meat, could alleviate scurvy. Conversely, in other cases, a meat-only diet could cause scurvy.

Scott's 1902 Antarctic expedition used lightly fried seal meat and liver, whereby complete recovery from incipient scurvy was reported to have taken less than two weeks.

Due to the risks especially in adolescents, of cognitive impairments and possible irreversible brain damage associated with binge drinking, urgent action has been recommended. There is some evidence that interventions by employers such as, health and life-style checks, psychosocial skills training and peer referral, can reduce the level of binge drinking. In the US brief motivational interventions have shown some benefit in reducing future binge drinking.

Adolescents who misuse alcohol can benefit from interventions aimed at risk reduction. For more severe cases an intervention involving parents, guardians, and/or a psychotherapist is recommended. An effective strategy of intervention for adolescents whose binge drinking leads to admission to hospital, e.g. for alcohol poisoning or injury, is manualised brief interventions at the hospital in one to four counseling sessions each lasting 30 to 60 minutes conducted by trained staff. Evaluation of personal pattern of drinking and associated risks and an emphasis on personal responsibility in a non-condescending manner is recommended during the intervention; discussing and informing/educating the adolescent of possible negative short and long-term consequences of drinking is recommended. The setting of goals and rules to achieve those goals is also recommended during intervention with problem binge drinking adolescents.

Increasing public information and awareness regarding the risks of binge drinking, conducting interviews in emergency departments of young people suspected of harmful drinking patterns and trying to persuade them to accept individual counseling in youth addiction counseling services are effective strategies for reducing the harm of binge drinking. Encouraging recreational and adventurous training activities such as climbing or driving can be used alternative "natural buzzes" to alcohol misuse. Additionally the provision of educational content about the risks of binge drinking and a risk assessment are beneficial during intervention with young binge drinkers and a referral in the case of an alcohol use disorder for specialised help.

According to the NIAAA definition of "heavy drinkers", men may be at risk for alcohol-related problems if their alcohol consumption exceeds 14 standard drinks per week or 4 drinks per day, and women may be at risk if they have more than 7 standard drinks per week or 3 drinks per day. Despite this risk, a 2014 report in the National Survey on Drug Use and Health found that only 10% of either "heavy drinkers" or "binge drinkers" also met the criteria for alcohol dependence, while only 1.3% of non-binge drinkers met this criteria. An inference drawn in this study is that evidence-based policy strategies and clinical preventive services may effectively reduce binge drinking without requiring addiction treatment in most cases.

Binge drinking is considered harmful, regardless of a person's age, and there have been calls for healthcare professionals to give increased attention to their patients drinking habits, especially binge drinking. Some researchers believe that raising the legal drinking age and screening brief interventions by healthcare providers are the most effective means of reducing morbidity and mortality rates associated with binge drinking. Programs in the United States have thought of numerous ways to help prevent binge drinking. The Centers for Disease Control and Prevention suggests increasing the cost of alcohol or the excise taxes, restricting the number of stores who may obtain a license to sell liquor (reducing "outlet density"), and implementing stricter law enforcement of underage drinking laws. There are also a number of individual counseling approaches, such as motivational interviewing and cognitive behavioral approaches, that have been shown to reduce drinking among heavy drinking college students. In 2006, the Wisconsin Initiative to Promote Healthy Lifestyles implemented a program that helps primary care physicians identify and address binge drinking problems in patients. In August 2008, a group of college presidents calling itself the Amethyst Initiative asserted that lowering the legal drinking age to 18 (presumably) was one way to curb the "culture of dangerous binge drinking" among college students. This idea is currently the subject of controversy. Proponents argue that the 21 law forces drinking underground and makes it more dangerous than it has to be, while opponents have claimed that lowering the age would only make the situation worse. Despite health warnings, most Australian women drink at least one night a week. But experts are warning they are not only damaging their bodies but are also at risk of attracting sexual predators.

Obesity in New Zealand has become an important national health concern in recent years, with high numbers of people afflicted in every age and ethnic group. As of June 2008, 26.5% of New Zealanders are obese, a number only surpassed in the English-speaking world by the United States.

HIV/AIDS is a major public health concern and cause of death in many parts of Africa. Although the continent is home to about 15.2 percent of the world's population, more than two-thirds of the total, some 35 million infected, were Africans, of whom 15 million have already died. Sub-Saharan Africa alone accounted for an estimated 69 percent of all people living with HIV and 70 percent of all AIDS deaths in 2011. In the countries of sub-Saharan Africa most affected, AIDS has raised death rates and lowered life expectancy among adults between the ages of 20 and 49 by about twenty years. Furthermore, the life expectancy in many parts of Africa is declining, largely as a result of the HIV/AIDS epidemic with life-expectancy in some countries reaching as low as thirty-four years.

Countries in North Africa and the Horn of Africa have significantly lower prevalence rates, as their populations typically engage in fewer high-risk cultural patterns that have been implicated in the virus's spread in Sub-Saharan Africa. Southern Africa is the worst affected region on the continent. As of 2011, HIV has infected at least 10 percent of the population in Botswana, Lesotho, Malawi, Mozambique, Namibia, South Africa, Swaziland, Zambia, and Zimbabwe.

In response, a number of initiatives have been launched in various parts of the continent to educate the public on HIV/AIDS. Among these are combination prevention programmes, considered to be the most effective initiative, the abstinence, be faithful, use a condom campaign, and the Desmond Tutu HIV Foundation's outreach programs.

According to a 2013 special report issued by the Joint United Nations Programme on HIV/AIDS (UNAIDS), the number of HIV positive people in Africa receiving anti-retroviral treatment in 2012 was over seven times the number receiving treatment in 2005, "with nearly 1 million added in the last year alone". The number of AIDS-related deaths in Sub-Saharan Africa in 2011 was 33 percent less than the number in 2005. The number of new HIV infections in Sub-Saharan Africa in 2011 was 25 percent less than the number in 2001.

As a consequence of high rate of obesity, Nauru has the highest rate of adult diabetes in the world. The International Diabetes Federation (IDF) identified 31% of Nauruans as diabetic. This rate is as high as 45% among the age group 55-64.

Many people living with HIV in low and middle income countries who need antiretroviral therapy are unable to access or remain in care. This is often because of the time and cost required to travel to health centres as well as an inadequate number of trained staff such as medical doctors and specialists to provide treatment. One approach to improve access to HIV care is to provide antiretroviral therapy close to people’s homes. A systematic review found that when antiretroviral treatment was initiated at the hospital but followed up at a health centre closer to home, fewer patients died or were lost to follow up. The research also did not detect a difference in the numbers of patients who died or were lost to follow up when they received maintenance treatment in the community rather than in a health centre or hospital.
