I think that is the whole point. Obesity is defined as a BMI over 30 and obesity would be listed as a comorbidity. Almost half of US adults also have high blood pressure, also a comorbidity. These are some of the reasons 94% of Covid deaths had a comorbidity listed and a lot had more than one.
Agreed, BMI is a joke and alone should never be considered a comorbidity. In my opinion, slightly high BP alone shouldn’t be considered a comorbidity either.
To be honest, I don’t trust any of the numbers at this point.... I don’t know what to believe on either side of the debate at this point.
