In particular, the elderly and people with previous illnesses more often suffer from a severe course of Covid-19. However, a current study shows that even being slightly overweight could be dangerous.
It is well known that being excessively overweight can be harmful to health. Studies have also already shown that obesity can have a negative impact on the course of Covid 19 disease. Researchers from Great Britain are now investigating whether even being slightly overweight and normal weight have an effect on the corona risk.
High body mass index can increase hospital risk
Scientists at New York’s “NYU Langone Medical Center” found in 2020 that a high body mass index increases the risk of being hospitalized with Covid 19. According to the study, it increases in people with a body mass index (BMI) of more than 40. Obesity is about as much at risk for patients as heart failure and significantly more than lung or cancer diseases.
Thus, being very overweight counts in addition to cardiovascular diseases and Diabetes one of the most common risk factors for a severe course of Covid-19. As the Ärzteblatt reported, obesity also increases the risk of being cared for in intensive care or even dying.
These findings also coincide with observations from other countries. Doctors from Wuhan already found in spring 2020 that more than 88 percent of those who died of Covid-19 had a BMI of over 25 and were therefore overweight to obese.
Why are overweight people more likely to get Covid-19?
So far it is unclear why obese patients more often suffer a severe course of Covid-19. The scientists suspect that the inflammatory responses that occur in obesity may play a role. In severe cases of Covid-19, this often results in an uncontrolled overshoot of the immune system, which can lead to circulatory shock and multiple organ failure.
In addition, there is the fact that being overweight also leads to a lower level of defense of the immune system with other infections and that people who are severely overweight are more prone to infections anyway.
Study: From this BMI, the risk of Covid 19 disease increases
A team of researchers from Oxford University evaluated data from 6.9 million patients from 1,500 primary care practices in the UK who had at least one BMI measurement. Within this cohort, 13,503 people were hospitalized for Covid-19 between January and April last year. 1,601 of them had to be treated in intensive care units. A total of 5,479 patients died of or with Covid-19.
The analysis showed that the risk of hospitalization increased linearly from a BMI of 23, i.e. already below the overweight limit, which is 25. The risk of death was increased from a value of 28, i.e. below the threshold for obesity. The results were published in the English language journal “Lancet Diabetes & Endocrinology”.
Obesity: How To Calculate Your BMI
According to the Robert Koch Institute, around a quarter of adults in Germany are obese. To determine whether you are overweight or even obese, you can easily calculate your body mass index (BMI). To do this, you need to divide your weight by your height in meters squared.
You can find a simple BMI calculator here.
A healthy BMI is between 19 and 25. If you have a lower BMI, you are most likely underweight; if your BMI rises above 25, you are overweight. Someone is considered obese if their BMI is over 30.
