Like many other medical conditions, obesity is the result of an interplay between environmental and genetic factors. [2] [3] Studies have identified variants in several genes that may contribute to weight gain and body fat distribution, although only in a few cases are genes the primary cause of obesity. [4] [5]
When ghrelin levels are high — often during periods of calorie restriction or weight loss attempts — it can lead to increased hunger and potentially hinder weight loss efforts. designer491 ...
Weight gain is an increase in body weight. This can involve an increase in muscle mass , fat deposits , excess fluids such as water or other factors. Weight gain can be a symptom of a serious medical condition.
Thiazolidinediones may cause slight weight gain but decrease "pathologic" abdominal fat (visceral fat), and therefore may be prescribed for diabetics with central obesity. [115] Thiazolidinedione has been associated with heart failure and increased cardiovascular risk; so it has been withdrawn from the market in Europe by EMA in 2010. [116]
Weight fluctuations of five pounds are more are uncommon among men. Experts explain common sudden weight gain causes, what to do, and when to see a doctor. 12 Common Causes of Sudden Weight Gain
Hungry Gut Gene Affects Weight Loss Drug ... during which the researchers recorded total body weight loss at 3, 6, 9, and 12 months. Researchers then determined the probability of a positive ...
Aromatase excess syndrome (AES or AEXS) is a rarely diagnosed genetic and endocrine syndrome which is characterized by an overexpression of aromatase, the enzyme responsible for the biosynthesis of the estrogen sex hormones from the androgens, in turn resulting in excessive levels of circulating estrogens and, accordingly, symptoms of hyperestrogenism.
In medicine, genetic susceptibility to a disease refers to a genetic predisposition to a health problem, [1] which may eventually be triggered by particular environmental or lifestyle factors, such as tobacco smoking or diet. Genetic testing is able to identify individuals who are genetically predisposed to certain diseases.
