Why is obesity genetic?
Genetically, obesity is a condition in which one’s genes have been altered by a single environment or illness.
People who carry the gene for obesity are more likely to develop type 2 diabetes, heart disease and stroke.
Genetically obese people are more susceptible to certain types of cancers and other diseases, according to a 2016 study published in the American Journal of Public Health.
Obesity affects more than 200 million people worldwide, according the World Health Organization.
The condition has also been linked to a wide variety of health issues, including cancer, cardiovascular disease, diabetes, depression, and stroke, according for the U.S. Centers for Disease Control and Prevention.
However, studies have been scarce to understand the true causes and extent of obesity.
Genetic variants that can cause obesity have been found in humans as far back as the first half of the 20th century, and there is strong evidence that the condition may be influenced by a number of genes, according.
Genetic variation between the people carrying a particular gene is linked to the number of calories that a person burns, according Harvard Medical School.
Some of these variations are linked to changes in a person’s metabolism, but others are linked specifically to the amount of fat stored in the body.
Some people, like people with Type 2 diabetes and those with heart disease, may be more prone to obesity.
Researchers have found genetic variations that can influence the weight of people’s bodies.
Obesity is the third leading cause of death worldwide, after smoking and cardiovascular disease.
People with Type 1 diabetes and heart disease have a greater risk of obesity than people without the condition, according data from the U-M Health Center.
Genetic variations that affect fat storage have been linked in the past to heart disease.
A genetic mutation in the gene that causes type 2 obesity is associated with a higher risk of developing heart disease or high blood pressure, according a 2013 study published online in the journal Science.
In the same study, researchers also found that a mutation in a gene associated with the growth of fat cells in the heart is linked with a high risk of heart attacks.
There is evidence that genetic variants can influence muscle mass and strength, according research published in Cell Reports in 2014.
People whose genetic variations influence fat storage also have a higher chance of developing diabetes, according genetic counselors and experts from the National Institute on Aging.
In a 2012 study, scientists at Duke University analyzed the genetic variation in two individuals who had different levels of fat storage and found that they had the same risk of type 2 hypertension, which is a major risk factor for the disease.
Some genetic variations associated with obesity have also been found to be associated with diabetes.
One variant linked to obesity in people with type 2, or “metabolically obese,” diabetes has been linked with diabetes risk in people who are overweight or obese.
In one study, participants with the Metabolic Risk Variables (MRV) rs7382949 in the Metabolically Obese Individuals Genetic Variant (MIU) subgroup were at a greater increased risk of having Type 2 or Type 3 diabetes, the researchers found.
Another variant in people carrying the Metabesity Variant 1 (MUV1) rs6394022 in the Obesity Variant 1 (OV1) sub-group was linked to higher risk for developing type 2 or 3 diabetes.
The researchers found that those with the MIU variant had an increased risk for Type 2 and 3 diabetes compared to those who had the MUV1 variant.
