Overweight and obesity have long been labeled as two contributing factors to a variety of health and morbidity issues, meaning we are used to thinking of them as an absolute health disadvantage.

But a new study has come to a slightly different conclusion, according to which obese people have a better chance of surviving diseases and infections that can be fatal.

According to researchers from the University of Gothenburg in Sweden, people with a larger waist circumference are at lower risk of dying from bacterial infections, compared to thin and shapely people.

Studies so far have well established the link between obesity and health problems like diabetes, heart disease and even certain types of cancer.

"In the context of most diseases, overweight and obesity are considered a disadvantage. And this relationship is true for cardiovascular disease, cancer and even covid-19 - all of which have a high BMI and are associated with higher mortality. But paradoxically, in our study we found an inverse relationship," said the senior researcher. Dr. Asa Alessio, in a press release.

BMI (body mass index) is an accepted measure by which doctors and professionals evaluate a healthy weight, which weighs the ratio between height and weight.

For most adults, a normal BMI is in the range of 18.5-24.9.

BMI over 25 is considered overweight, and over 30 obesity.

Obesity is now considered a common problem among populations of many countries.

Obesity provides a survival advantage in certain situations.

Do people of normal weight die more from infections?

The researchers in the current study followed 2,196 patients who were hospitalized and treated for bacterial infections at Scarburg Hospital in Sweden for 9 months. In the

group of study participants with normal weight, 26 percent of the patients died within a year of their hospitalization, and among the group of overweight and obese people, this figure was only 9-17 percent. .

the findings of the Swedish study, published in PLOS One journal, confirms what researchers call "survival and obesity paradox" actually refers to the relative survival lead of standing people with obesity or being overweight, cases of bacterial infections.

"We know this benefit exists, what we do not know is how exactly it works," said Dr. Alessio. It is regulated.

We need more information about the effects of being overweight on the immune system.

One of the groups that can be used in a research group for this purpose is people with obesity who undergo bariatric surgery. "

"Obesity is spreading worldwide at an alarming rate, and we need more information than about how higher weights affect the body's defense against infection, so that we can match the right treatment," added Dr. Ganryu Jacobson, who also took part in the study.

Increasing Databases on the link between weight and morbidity can also help improve the treatment given to patients with viral diseases, such as coronary heart disease.

It is possible that the information we collect about obese patients' coping with bacterial infections could also be used to improve the chances of recovery of overweight Corona patients, "Dr. Jacobson added.
