"Metabolic" surgery associated with lower Covid risk than non-ops

I put "metabolic" in quotes because they only included sleeve and RNY. But it should apply to DSers even more. However, note that the comparison is non-ops with morbid obesity, not normal weight people.

Conclusion: Prior metabolic surgery with subsequent weight loss and improvement of metabolic abnormalities was associated with lower rates of hospital and ICU admission in patients with obesity who became infected with SARS-CoV-2. Confirmation of these findings will require larger studies

I wished I had paid more attention to something my husband said. He saw an article discussing how vitamin D deficiency is a risk for Covid. He knows that I am not deficient. I did find this:

Does vitamin D protect against COVID-19?
There is some evidence to suggest that vitamin D might help protect against becoming infected with, and developing serious symptoms of, COVID-19. We know, for example, that people with low vitamin D levels may be more susceptible to upper respiratory tract infections. One meta-analysis found that people who took vitamin D supplements, particularly those who had low vitamin D levels, were less likely to develop acute respiratory tract infections than those who didn't.
Vitamin D may protect against COVID-19 in two ways. First, it may help boost our bodies' natural defense against viruses and bacteria. Second, it may help prevent an exaggerated inflammatory response, which has been shown to contribute to severe illness in some people with COVID-19.

Does this say something other than…the more obese you are the more at risk you are?

That’s all I get out of it.

That's about it... but it could be worse.. you could loose the weight and still have the problem

The control group here is the obese population... not the normal weight population

That said, the problems of covid with obesity are severe (see fig)


"To our knowledge, this is the first clinical study to demonstrate that prior metabolic surgery with subsequent weight loss and improvement of metabolic abnormalities could potentially reduce morbidity from SARS-CoV-2 infection."

Fwiiw... the surgery group was, on average, still stage 2 obese ( bmi ~37), and more obese than the contol group (bmi~47) before surgery (bmi ~49)

"The average BMI of the surgical group was 49.1 +- 6 8.8 kg/m2 before metabolic surgery and was down to 37.2 +- 7.1 at the time of SARS-CoV-2 testing, compared with the control group’s BMI of 46.7 6 6.4 kg/m2.

They match the groups for a number of comorbidities, but not for diabetes, hypertension or meds

"to balance the distributions between the 2 groups at the time of a positive viral test for age, sex, race, ethnicity, location (Ohio versus Florida), smoking status, and history of chronic obstructive pulmonary disease (COPD), asthma, or cancer. Patients were not intentionally matched based on the BMI and cardiometabolic risk factors (e.g., hypertension and diabetes) or medications at the time of viral test, since favorable changes on those factors could be the potential derivers for improvement of outcomes after metabolic surgery.
