A new Lancet study reveals that obesity increases the risk of serious infectious diseases by 70%, including influenza and pneumonia. The research shows that individuals with higher body mass index face significantly greater chances of hospitalization when contracting these illnesses.

The findings highlight a critical public health concern, as obesity rates continue to climb globally. Medical experts emphasize that excess weight can impair immune function and respiratory capacity, making individuals more vulnerable to severe infections that require hospital care.

Healthcare systems may need to prepare for increased strain during flu seasons and potential pandemics, given the growing prevalence of obesity. The study underscores the importance of weight management as a preventive health strategy against serious infectious diseases.
