Nutritional anemia refers to the low concentration of hemoglobin due to poor diet. According to the World Health Organization, a hemoglobin concentration below 7.5 mmol/L and 8. mmol/L for women and men, respectively, is considered to be anemic. Thus, anemia can be diagnosed with blood tests. Hemoglobin is used to transport and deliver oxygen in the body. Without oxygen, the human body cannot undergo respiration and create ATP, thereby depriving cells of energy.

Nutritional anemia is caused by a lack of iron, protein, B12, and other vitamins and minerals that needed for the formation of hemoglobin. Folic acid deficiency is a common association of nutritional anemia and iron deficiency anemia is the most common nutritional disorder.

Signs of anemia include cyanosis, jaundice, and easy bruising. In addition, anemic patients may experience difficulties with memory and concentration, fatigue, lightheadedness, sensitivity to temperature, low energy levels, shortness of breath, and pale skin. Symptoms of severe or rapid-onset anemia are very dangerous as the body is unable to adjust to the lack of hemoglobin. This may result in shock and death. Mild and moderate anemia have symptoms that develop slowly over time.[5] If patients believe that they are at risk for or experience symptoms of anemia, they should contact their doctor.

Treatments for nutritional anemia includes replacement therapy is used to elevate the low levels of nutrients.[1] Diet improvement is a way to combat nutritional anemia and this can be done by taking dietary supplements such as iron, folate, and Vitamin B12.[2] These supplements are available over-the-counter however, a doctor may prescribe prescription medicine as needed, depending on the patient’s health needs.

Internationally, anemia caused by iron deficiencies is the most common nutritional disorder. It is the only significantly prevalent nutritional deficiency disorder in industrialized countries. In poorer areas, anemia is worsened by infectious diseases such as HIV/AIDS, tuberculosis, hookworm infestation, and Malaria. In developing countries, about 40% of preschool children and 50% of pregnant women are estimated to be anemic. 20% of maternal deaths can be contributed to anemia. Health consequences of anemia include low pregnancy outcome, impaired cognitive and physical development, increased rate of morbidity, and reduced rate of work in adults.

Nutritional Anemia has many different causes, each either nutritional or non-nutritional. Nutritional causes are vitamin and mineral deficiencies and non-nutritional causes can be infections. The number one cause of this type of anemia however is iron deficiency.

An insufficient intake of iron, Vitamin B12, and folic acid impairs the bone marrow function.

The lack of iron within a person’s body can also stem from ulcer bacteria. These microbes live in the digestive track and after many years cause ulcer’s in the lining of your stomach or small intestine. Therefore, a high percentage of patients with nutritional anemia may have potential gastrointestinal disorder that causes chronic blood loss. This is common in immunocompromised, elderly, and diabetic people. High blood loss can also come from increases loss of blood during menstruation, childbirth, cancers of the intestines, and a disorder that hinders blood’s ability to coagulate.

Medications can have adverse effects and cause nutritional anemia as well. Medications that stop the absorption of iron in the gut and cause bleeding from the gut (NSAIDs and Aspirin) can be culprits in the development of this condition. Hydrocortisones and valproic acid are also two drugs that cause moderate bleeding from the gut. Amoxicillin and phenytoin are the ability to cause a vitamin B12 deficiency.

Other common causes are thyroid disorders, lead toxcities, infectious diseases (e.g Malaria), Alcoholism, and Vitamin E deficiency.

Symptoms

Symptoms of nutritional anemia can include fatigue and lack of energy. However if symptoms progress, one may experience shortness of breath, rapid pulse, paleness --especially in the hands, eyelids and fingernails---, swelling of ankles, hair loss, lightheadedness, compulsive and atypical cravings, constipation, depression, muscle twitching, numbness, or burning and chest pain.

Those who have nutritional anemia often show little to no symptoms. Often, symptoms can go undetected as mild forms of the anemia have only minor symptoms.

Nutritional anemia refers to types of anemia that can be directly attributed to nutritional disorders.

Examples include Iron deficiency anemia and pernicious anemia.

It is often discussed in a pediatric context.

Megaloblastic anemia (MA) is associated with GSE and is believed to be the result of B and folate deficiency. In GSE, it appears to be associated with the IgA-less phenotype. Unlike other forms of megaloblastic anemia, GSEA MA is not a form of autoimmune gastritis.

Pernicious anemia (PA). Pernicious anemia is associated with GSE and is believed to result primarily from malabsorption phenomena.

Iron-deficiency anemia. Iron-deficiency anemia (IDA) may be the only symptom for CD, detected in subclinical CD and is accompanied by a decrease in serum ferritin levels. This can cause addition problems (see:symptoms of IDA and certain conditions like such as Paterson-Brown Kelly (Plummer-Vinson). Whereas IDA is corrected on GF diet, refractory disease or gluten-sensitive malignancies can cause persistent IDA.

Thromboembolism is a well-described complication of IBD, with a clinical incidence of up to 6% and a three-fold higher risk of disease, and the Factor V Leiden mutation further increases the risk of venous thrombosis. Recent studies describe the co-occurrence between coeliac disease, in which IBD is common in venous thrombosis.

Although often termed a "neurological condition," synesthesia is not listed in either the DSM-IV or the ICD since it most often does not interfere with normal daily functioning. Indeed, most synesthetes report that their experiences are neutral or even pleasant. Like perfect pitch, synesthesia is simply a difference in perceptual experience.

The simplest approach is test-retest reliability over long periods of time, using stimuli of color names, color chips, or a computer-screen color picker providing 16.7 million choices. Synesthetes consistently score around 90% on reliability of associations, even with years between tests. In contrast, non-synesthetes score just 30–40%, even with only a few weeks between tests and a warning that they would be retested.

Grapheme-color synesthetes, as a group, share significant preferences for the color of each letter (e.g. A tends to be red; O tends to be white or black; S tends to be yellow etc.) Nonetheless, there is a great variety in types of synesthesia, and within each type, individuals report differing triggers for their sensations and differing intensities of experiences. This variety means that defining synesthesia in an individual is difficult, and the majority of synesthetes are completely unaware that their experiences have a name.

Neurologist Richard Cytowic identifies the following diagnostic criteria for synesthesia in his "first" edition book. However, the criteria are different in the second book:

1. Synesthesia is involuntary and automatic.

2. Synesthetic perceptions are spatially extended, meaning they often have a sense of "location." For example, synesthetes speak of "looking at" or "going to" a particular place to attend to the experience.

3. Synesthetic percepts are consistent and generic (i.e. simple rather than pictorial).

4. Synesthesia is highly memorable.

5. Synesthesia is laden with affect.

Cytowic's early cases mainly included individuals whose synesthesia was frankly projected outside the body (e.g. on a "screen" in front of one's face). Later research showed that such stark externalization occurs in a minority of synesthetes. Refining this concept, Cytowic and Eagleman differentiated between "localizers" and "non-localizers" to distinguish those synesthetes whose perceptions have a definite sense of spatial quality from those whose perceptions do not.

Synesthesia is found in at least 4.4% of the population, as a high estimate, which is equivalent to 1 in 23 people. This study had also concluded that one common form of synesthesia—grapheme-color synesthesia (colored letters and numbers) – is found in more than one percent of the population, and this latter prevalence of graphemes-color synesthesia has now been independently verified in a yet larger sample. Earlier estimates of the prevalence of synesthesia were based on "best-guess" estimations only ("e.g." 1 in 250,000) or had limitations in their methodologies because they required synesthetes to refer themselves for study ("e.g." 1 in 2000) and for this reason the authors of those studies had been moderate in their claims. Also, some individuals will not self-classify as synesthetes because they do not realize that their perceptions are different from those of everyone else.

The most common forms of synesthesia are those that trigger colors, and the most prevalent of all is day-color. Also relatively common is grapheme-color synesthesia. We can think of "prevalence" both in terms of how common is synesthesia (or different forms of synesthesia) within the population, or how common are different forms of synesthesia within synesthetes. So within synesthetes, forms of synesthesia that trigger color also appear to be the most common forms of synesthesia with a prevalence rate of 86% within synesthetes. In another study, music-color is also prevalent at 18–41%. Some of the rarest are reported to be auditory-tactile, mirror-touch, and lexical-gustatory.

There is research to suggest that the likelihood of having synesthesia is greater in people with autism.

Congenital cystic eye (also known as "CCE" or "cystic eyeball") is an extremely rare ocular malformation where the eye fails to develop correctly "in utero" and is replaced by benign, fluid-filled tissue. Its incidence is unknown, due to the very small number of cases reported. An audit by Duke-Elder of the medical literature from 1880 to 1963 discovered only 28 cases. The term was coined in 1937 by the renowned ophthalmologist Ida Mann.

Embryologically, the defect is thought to occur around day 35 of gestation, when the vesicle fails to invaginate. Dysgenesis of the vesicle later in development may result in coloboma, a separate and less severe malformation of the ocular structures.

CCE is almost always unilateral, but at least 2 cases of bilateral involvement have been described. Patients may also present with skin appendages attached to the skin surrounding the eyes. Association with intracranial anomalies has been reported.

Treatment of CCE is usually by enucleation, followed by insertion of an ocular implant and prosthesis.
