Losing weight can reduce
the severity of Covid-19

There’s increasing evidence that people with obesity have a higher chance of contracting COVID-19. They’re also more likely to be hospitalised, to need ventilation, and to die from the disease. As two thirds of the Australian population are overweight or obese, a COVID-19 outbreak could easily take hold and have a huge negative impact.

But there is good news. When you treat obesity successfully, there is a higher chance of reducing COVID-19 complications. Surgical treatment also lowers other risks of obesity, including type 2 diabetes, cancer, and heart disease.

Medical Reference:

A person with obesity has 46% higher odds of contracting COVID-19

Obesity increases the odds of getting COVID-19 by 46%.1

It may also increase population infection as the viral load may be higher and viral shedding takes longer.

Obesity increases the risk of dying from COVID-19 death by 48%.1

The risk of death increases with the level of obesity – those with a BMI of above 40 are more likely to have a negative outcome when infected with COVID-19.

Treatments of severe complications

COVID-19 patients who are obese are 74% more likely to be admitted to the intensive care unit.

Studies also found a 66% increase in invasive mechanical ventilation for patients who also had obesity.1
