Weight gain risky for obese, but loss of over 10 kg increases the risk of death by 50%

Can weight loss always be a response to obesity? Although it is well known that gaining weight increases the risk of heart and death diseases, scientists have now stated that the loss of significant weight can also have their own set of threats.

In the last study, scientists from England Ruskin University (ARU) in Great Britain stated that in the case of people with obesity, “maintaining stable weight, even in obese,” can help reduce the risk of death, especially for people with risk factors of heart disease.

“Perhaps it was not surprising that a significant weight gain was associated with higher mortality, but interesting that a similar association was found among those who lost great importance,” said researcher Dr. Jufen Zhang Wa press release.

The study analyzed data from over 8,000 obese participants from the British Biobank study, from which cardiovascular diseases were diagnosed. These people were followed for almost 14 years, and scientists strictly monitored changes in their weight all the time.

The discoveries revealed that participants who gained over 10 kg during the study had a threefold increase in the risk of cardiovascular death and almost twice the risk of death for any reason, compared to those who maintained stable weight.

However, the study discovered an even more striking discovery: those who lost more than 10 kg faced 54% of a higher risk of mortality for any reason. This suggests that although obese people are often encouraged, significant weight loss may have side effects, especially in people at risk of cardiovascular problems.

“This study is the first of its kind that has examined the relationship between body weight and mortality for any reason in obese people with cardiovascular disease,” Dr. Zhang.

While further research is needed to fully understand the basic mechanisms associated with both weight loss and the increased risk of death, Dr. Zhang advises that “clinicians should be careful, especially in the case of new drugs on the market that are promoted to quickly lose weight.”

“While weight loss is generally recommended for obese adults, people in endangered groups, like these people, should only take up weight loss under the strict direction of the doctor,” Dr. Zhang added.
