How does obesity affect infection risk according to the UK study?

The study indicates that obesity weakens the body's defenses against infections, leading to more severe diseases and a harder recovery process.

What is the global impact of obesity on infection-related deaths?

Globally, obesity was associated with one in 10 infection-related deaths in 2023, according to the research.

Can weight loss drugs help reduce infection risks linked to obesity?

Yes, experts suggest that weight loss drugs show promise in meaningfully reducing deaths from infections and offer broader health benefits.

Obesity Fuels Deadly Infections: UK Study Warns

A recent study involving over 540,000 individuals from Finland and the UK highlights a significant link between obesity and increased susceptibility to infectious diseases. Researchers found that obesity is associated with a 70% higher risk of hospital admission or death from infections, and this connection is not solely due to related chronic conditions.

The research, published in The Lancet, indicated that obesity might weaken the body's immune defences. This can manifest through altered gut microbiomes, reduced lung capacity, and changes in blood flow. The findings suggest that while people with obesity may not contract infections more easily, their recovery is considerably harder.
