There are no known contraindications from a weight-loss surgical perspective to prevent a post-surgical patient from getting the COVID vaccines.

A patient who has had a Duodenal Switch, Lap Sleeve Gastrectomy, RNY Gastric Bypass, or revisions to Weight Loss Surgery should have the COVID vaccine. The vaccination should be avoided for a few weeks after surgery. For other possible contraindications, please consult your PCP.

Here is a summary of the vaccines and the details of each one approved as of the publication date.

 

 

 

Physical activity in the U.S. varies based on geographic location, socioeconomic status and in comparison to other countries. It is important to know that physical activity is an important component of our well-being. However, this does not mean that going to the gym is the only way to be physically active.

Strain et al. Shows that different populations in different countries get their activity from different sources.

His research showed that the United States population ranked as a high-income country, ranks in the lower 1/3 of the number of countries surveyed with regards to the meeting minutes of moderate-to-vigorous physical activity (MVPA) per week.  This may be a contributing factor to the significant rise in obesity in the United States. Individually we should all aim to increase our moderate to vigorous activity significantly.

We are all aware of the many roles that Vitamin D plays in our bodies. This includes immune function in addition to all the regulatory roles that Vitamin D plays in several physiologic reactions. There may be a correlation of low Vitamin D and COVID-19 infection increasing death risk as looked at in research articles.

Covid -19 in a subset of patience causes significant lung injury. These patients require mechanical ventilation.

Previously reported publications have suggested a possible correlation between ace inhibitors and increased risk of pulmonary complications of Covid -19. Some researchers suspect that the Covid-19 may be able to enter lung cells by the ACE receptors.

Vitamin D may positively implact the receptor ACE2. This study, report clear correlation between the high death rate with low vitamin D levels in Covid infected patients. There are limitation to this study that the attached abstract outlines.

Our take home message would be to please make sure you have updated labs and that you are all taking the recommended Vitamin D based on your surgical anatomy and laboratory values, not just an average non-bariatric person recommended dose.

The scientific literature is riddled with evidence pointing to the benefit of early metabolic surgery as a superior treatment, remission and possible cure option for diabetes.  Unfortunately, the medical education, pharmaceutical companies, primary care healthcare delivery systems and third party payers (health insurance companies) have not caught up with the published data. The American Diabetes Association has changed their guidelines to reflected the benefit for combating diabetes with weight loss surgery.

There is ample evidence of the superior outcome of surgery as a treatment option for diabetes when compared to medical managment. Cummings et.al, in a published article in Diabetes Care, showed sustained stabilization of the Hemoglobin A1C six years after surgery. In contrast, there was no significant changes noted in the non-surgical group.

 

 

Jans et.al. , in November of 2019 showed that the patients who had NOT been on Insulin,  and had metabolic surgery had the highest long term success for resolution and remission of the diabetes. This identifies that having a patient be proactive in their care by having metabolic surgery improves success rates.

 

The exact mechanism by which the diabetes is resolved is unclear. The weight loss may play a role. There are numerous hormones and neuroendocrine modulators which control the complex metabolic pathways. Batterham et.al., in Diabetes Care (2016),  published a summary overview of the possible mechanism involved in diabetes improvement following metabolic surgery.

 

 

There are a number of overlapping and sequential layers for possible reasons why diabetes resolves after weight loss/metabolic surgery. These may be directly related to surgery and the reduction of the calorie intake or absorption. It may also involve the neuroendocrine modulators.

 

What can be said definitively is that early surgical intervention is best and most likely the only permanent solution to type II diabetic resolution. There is no medical justification in not considering metabolic surgery in diabetic patients who may also have difficulty with meaning a BMI< 35.

Weight loss surgical procedures, in one form or another, achieve the desired effect of weight loss by altering absorption of fat, protein, and carbohydrates. This results in decreased total absorption of required calories.

An unintended consequence is the altered absorption of medications. Frequently I am asked about the specific medication. Usually the answer is vague since the information is limited on specific medications. If the desired effect is not achieved, then it is probably  not being absorbed well. Specially, if the same dose of the same medication working well before surgery.

There is a summary article about the Theoretical absorption pattern of different weight loss surgical procedures.

It’s important to understand Vitamin D metabolism and deficiency potential following weight loss surgery Vitamins after DS need to be followed via laboratory blood studies. There are basic vitamin needs but individual needs should be based on medical history, genetics, alimentary limb length, common channel length and other surgical and physiologic determinations. Vitamins after DS are a life long commitment as well as protein needs and hydration. Duodenal Switch is a malabsorptive procedure which requires at least yearly laboratory blood studies, daily vitamins/minerals, daily high protein and daily hydration intake. There is not an all in one vitamin that is adequate for a DS patient or tailored to your individual needs. (example: you may need more Vitamin D and less Vitamin A if you are taking a all-in-one vitamin you can’t get more of one and less of another vitamin)

DS patients are recommended to take Dry forms (water miscible form) of Vitamin A, D3, E, K due to the fat malabsorption after DS. Dry formulations by Biotech are processed so they can be absorbed by a water soluble method after the DS procedure. Vitamin D seems to be the vitamin that can become deficient the easiest, followed by Vitamin A. Take these vitamins away from dietary fat.

In some cases, patients may need injectable Vitamin A or D to improve vitamin levels.
