Obesity (BMI ≥40) is a significant independent risk factor for increased prevalence, severity, and lethality of COVID-19, primarily driven by metabolic dysregulation, chronic inflammation, and immune system attenuation.
If you have obesity, especially with a BMI over 40 or associated conditions like diabetes or high blood pressure, your risk of severe COVID-19 is significantly higher than that of a healthy-weight individual. This is not just about weight, but about how obesity affects your immune response and lung function. Prioritize prevention (vaccination, masking, distancing) aggressively, as your body may struggle more with the inflammation caused by the virus.
obesity is one of the most important conditions that increases exponentially the mortality risk of the SarS-coV-2 patients... novel data report more severe symptoms and even a negative prognosis for the obese patients.
Why this rating
The paper is a review citing multiple observational studies, cohort analyses, and mechanistic hypotheses, but lacks a single large-scale randomized controlled trial.

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
