Obesity Significantly Increases Risk of Severe Infections
Individuals with obesity face a substantially higher risk of severe infections, with some studies indicating a 70% increased chance of hospitalization due to infection, according to recent research. This connection highlights the critical importance of addressing obesity as a public health concern, as it can compromise the body’s ability to fight off illness.
The adipocyte, the cell that forms the basis of obesity, can increase in size or number in individuals who are obese. This can manifest as hypertrophic obesity, where cells enlarge, or an increase in the overall number of fat cells.
Obesity-associated conditions are numerous, but even modest weight reduction can lower the risk of cardiovascular disease, diabetes and obstructive sleep apnea. The findings underscore the potential benefits of weight management strategies for improving overall health and resilience against infection.
The research, which included literature searches up to May 2016, examined the effects of obesity on health and well-being, and how weight loss can improve these outcomes. The study considered terms such as “obesity,” “overweight,” “weight loss,” “comorbidity,” “diabetes,” “cardiovascular,” “cancer,” “depression,” “management,” and “intervention.”
The increased risk associated with obesity may have implications for public health strategies, including vaccination campaigns and infection control measures. Further research is needed to fully understand the mechanisms linking obesity and infection susceptibility.
