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.
Obesity isn’t just a matter of food and exercise — it may be in your genetic code, according to new research. “Obesity’s causes are very complex and in the majority of cases, the ...
The "a calorie is a calorie" model of obesity posits a combination of excessive food energy intake and a lack of physical activity as the cause of most cases of obesity. [96] A limited number of cases are due primarily to genetics, medical reasons, or psychiatric illness. [ 15 ]
Monogenic obesity is excess weight caused by a mutation in a single gene, as opposed to syndromic obesity not tied to a single gene variation and most obesity, which is caused by multiple genetic and environmental risk factors. Monogenetic obesity mostly affects the hypothalamus and leptin–melanocortin system (see hypothalamic obesity ...
Certain genetic conditions can also cause obesity. For example, Prader-Willi syndrome is an inherited disorder that leads to, among other complications, intellectual disability, a short stature ...
Obesity, in general, can increase your risk of: High blood pressure. High cholesterol. ... stress, alcohol consumption, and genetics. Menopause can cause belly fat in females too.
Pathophysiology of obesity is the study of disordered physiological processes that cause, result from, or are otherwise associated with obesity. A number of possible pathophysiological mechanisms have been identified which may contribute in the development and maintenance of obesity.
Steatopygia, a genetic characteristic leading to increased accumulation of adipose tissue in the buttock region, is most notably (but not solely) found among the Khoisan of Southern Africa. It has also been observed among Pygmies of Central Africa and also the Andamanese people, such as the Onge tribe in the Andaman Islands. This genetic ...
