Metabolic disorders Metabolic disorders Acute intermittent porphyria (AIP) is a rare metabolic disorder that is characterized by a deficiency of the enzyme, porphobilinogen deaminase ( PBG-D), also known as uroporphyrinogen I-synthase. This enzyme deficiency results in the accumulation of porphyrins or porphyrin precursors in the body. These are natural chemicals that normally do not accumulate in the body. This enzyme deficiency by itself is not sufficient to produce symptoms of the disease ( latent). Additional factors must also be present such as hormones, drugs and dietary changes that trigger the appearance of symptoms. Symptoms of AIP may include abdominal pain, constipation, and muscle weakness. ...more on Wikipedia about "Acute intermittent porphyria"
Alcohol flush reaction, (also known as Asian flush, Asian glow and ADH deficiency) is a condition where the body cannot break down ingested alcohol completely, due to a deficiency of an inactive enzyme, aldehyde dehydrogenase 2 (ALDH2) which is normally responsible for breaking down acetaldehyde, a byproduct of the metabolism of alcohol. Since acetaldehyde is a toxin, it accumulates and causes flushing if the human body can't break it down. Approximately half of all Asians have a sensitivity to alcohol due to this condition and there is some evidence that this condition exists frequently in people of Jewish descent as well. ...more on Wikipedia about "Alcohol flush reaction"
This list of causes of hypoglycemia is separated from the main article because of its length. Despite its length, it is not exhaustive, as new causes are reported regularly in the medical literature. In many individual instances of hypoglycemia, more than one contributing factor may be identifiable. In this list are some factors not usually sufficient to cause hypoglycemia by themselves. Some of these causes are represented by single case reports. ...more on Wikipedia about "Causes of hypoglycemia"
Fructose intolerance is a hereditary condition due to a deficiency of liver enzymes that metabolise fructose. Not to be confused with fructose malabsorption, a deficiency of fructose transporter enzyme in the enterocytes, which leads to abdominal bloating and diarrhea. ...more on Wikipedia about "Fructose intolerance"
Fructose malabsorption is a condition in which the fructose carrier in enterocytes is deficient. Symptoms and medical tests are similar as in lactose intolerance. This condition is common in patients with symptoms of irritable bowel syndrome. An appropriate diet can help. A small proportion of patients with both fructose malabsorption and lactose intolerance suffers from coeliac disease. ...more on Wikipedia about "Fructose malabsorption"
(Galactosemia) Galactosemia is a rare genetic metabolic disorder which affects an individual's ability to properly digest the sugar galactose. Lactose in food (such as dairy products) is broken down by the body into glucose and galactose. Normally, galactose is then converted into glucose by the enzyme GALT ( galactose-1-phosphate uridylyltransferase). In individuals with galactosemia, GALT activity is severely diminished, leading to toxic levels of galactose to build up in the blood, resulting in hepatomegaly (an enlarged liver), renal failure, cataracts, and brain damage. Without treatment, mortality in infants with galactosemia is about 75%. ...more on Wikipedia about "Galactosemia"
Glycogen storage disease type 0 is characterized by a deficiency in the glycogen synthase enzyme. Although glycogen synthase deficiency does not result in storage of extra glycogen in the liver, it is often classified with the GSDs because it is another defect of glycogen storage and can cause similar problems. ...more on Wikipedia about "Glycogen storage disease type 0"
Glycogen storage disease type III is characterized by a deficiency in glycogen debranching enzymes. It is also known as Cori's disease and Forbe's disease. It occurs in 1 in every 100,000 live births and it generally affects the liver. ...more on Wikipedia about "Glycogen storage disease type III"
Glycogen storage disease type IV also known as Glycogenosis type IV, Andersen's disease, Glycogen Branching Enzyme Deficiency (GBED), and polyglucosan body disease is a very rare hereditary metabolic disorder. ...more on Wikipedia about "Glycogen storage disease type IV"
Glycogen storage disease type V is a metabolic disorder, more specifically a glycogen storage disease, caused by a deficiency of myophosphorylase, the muscle isoform of the enzyme glycogen phosphorylase. This enzyme helps break down glycogen (a form of stored carbohydrate) into glucose so that it can be utilized within the muscle cell. ...more on Wikipedia about "Glycogen storage disease type V"
Hyperglycemia or High Blood Sugar is a condition in which an excessive amount of glucose circulates in the blood plasma. The term is from Greek: hyper-, prefix meaning "too much"; -glyc-, root meaning "sweet"; -emia, suffix meaning "of the blood". ...more on Wikipedia about "Hyperglycemia"
Hypoglycemia is a medical term referring to a pathologic state produced by a lower than normal amount of sugar ( glucose) in the blood. The term hypoglycemia literally means "low blood sugar". Hypoglycemia can produce a variety of symptoms and effects but the principal problems arise from an inadequate supply of glucose as fuel to the brain, resulting in impairment of function ( neuroglycopenia). Derangements of function can range from vaguely "feeling bad" to coma and (rarely) death. Hypoglycemia can arise from many causes, and can occur at any age. The most common forms of moderate and severe hypoglycemia occur as a complication of treatment of diabetes mellitus with insulin or oral medications. ...more on Wikipedia about "Hypoglycemia"
Lactose intolerance is the condition in which lactase, an enzyme needed for proper metabolization of lactose (a constituent of milk and other dairy products), is not produced in adulthood. With lactose intolerance, the result of consuming lactose or a lactose-containing food is excess gas production and often diarrhea. In western cultures milk products are nearly ubiquitous and are contained in at least a small amount in almost all recipes, restaurant dishes, and processed food. People with lactose intolerance need to read food ingredient labels carefully if they wish to avoid consuming lactose. ...more on Wikipedia about "Lactose intolerance"
A metabolic disorder is a medical disorder which affects the production of energy within individual human (or animal) cells. Most metabolic disorders are genetic, though a few are "acquired" as a result of diet, toxins, infections, etc. Genetic metabolic disorders are also known as inborn errors of metabolism. ...more on Wikipedia about "Metabolic disorder" Visit again http://www.shortopedia.com
Obesity is a condition where the natural energy reserve, stored in the fatty tissue of humans and mammals is increased to a point where it is thought to be a significant risk factor for certain health conditions as well as increased mortality. Obesity in wild animals is relatively rare, but it is common in domestic animals like pigs and household pets who may be overfed and underexercised. ...more on Wikipedia about "Obesity"
Pickardt-syndrome (or Pickardt-Fahlbusch-Syndrome) denotes a rare form of tertiary hypothyroidism that is caused by interruption of the portal veins connecting hypothalamus and pituitary, e.g. due to tumors compressing the infundibulum. ...more on Wikipedia about "Pickardt syndrome"
