Obesity and Covid 19
Being obese - overweight is know to increase the risk of a number of diseases including heart disease , cancer and type 2 diabetes .
Several studies have suggested links between Obesity and Covid 19 Mortality rates
In a study of nearly 17,000 hospital patients with Covid-19 in the UK, those who were obese - with a body mass index (BMI) of more than 30 - had a 33% greater risk of dying than those who were not obese.
A separate study of NHS electronic health records found a doubling of the risk of dying from Covid-19 among people who were obese. If other health conditions linked to obesity such as heart disease and type 2 diabetes were also taken into account the risk would be even higher, the researchers said.
And a study of critically ill patients in UK intensive care units found that nearly 34.5% were overweight, 31.5% were obese and 7% morbidly obese (a total of 73%), compared to 26% with a healthy BMI.
In China, where the outbreak began, data from 383 patients showed that having obesity was associated with a 142% higher risk of developing severe pneumonia associated with COVID-19.
A larger study of over 4,000 patients with COVID-19 in New York City found that severe obesity was a major risk factor for hospitalization, second only to age.
In Seattle, a study of critically ill COVID-19 patients made similar findings. This analysis found that 85% of patients with obesity required mechanical ventilation, compared to 64% of patients without the condition. Moreover, 62% of the patients with obesity died of COVID-19, compared with 36% of those without obesity. ( only 24 patients - all of whom were critically ill
analysis involved 124 patients in Lille, France, and also found that patients with obesity were more likely to require invasive mechanical ventilation.
Why is being obese a risk?
The more overweight you are, the more fat you're carrying, the less fit you are and the lower your lung capacity. This means it is a bigger struggle to get oxygen into the blood and around the body. This impacts on the heart and blood flow too.
"Because people are more overweight, they also have a demand for more oxygen. So that means their system is actually undergoing greater pressure," says Prof Naveed Sattar, from the University of Glasgow.
During an infection like coronavirus, this can be serious.
"Eventually the obese body becomes overwhelmed by the lack of oxygen getting to the major organs," says Dr Dyan Sellayah, from the University of Reading.
