Vitamins and surgery for obesity
More and more people are resorting to obesity surgery. 102,000 procedures were performed in Europe in 2014, nearly 47,000 in France, including 13,879 gastric bypasses and 27,761 sleeves.
Long-term physical and anatomical consequences, changes in the perception of the body, social cataclysms, changes in the way people view them and changes in diet are all factors that profoundly change the life of the person being operated on.
Nutrition is not just the introduction of calories into your body, but it is also a contribution of many trace elements that are essential for the proper functioning of the body and maintaining optimal health, which may be a long-term deficiency.
Thus, bariatric surgery results in deficiency of vitamins, minerals and trace elements.
Why Does Chronic Surgery Cause Vitamin Deficiency?
- Surgery causes a decrease in food intake.
- Food tolerance is changing completely, some foods and food families may be discarded
- Depending on the technique, the bypass involves a higher risk of defects
Therefore, post-surgery monitoring is required to prevent possible deficiency, regular blood tests and signs of defects will be required.
Therefore, in most cases you will need to take supplements with vitamins, minerals and trace elements daily.
For Sleeve Gastrectomy:
- Sleeve gastrectomy is an obesity surgery that causes an extreme reduction in the volume of the stomach in a vertical tube. The amount of food consumed during the day is lower. During the first months, the patient should get used to eating everything gradually. Therefore, there is a risk of vitamin deficiency after the sleeve, but also of minerals, as long as the patient is unable to eat enough and vary enough on a daily basis. The French national health authority mentions the need to add vitamins after the sleeve 6 to 12 months after the intervention.
- Risks of deficiency of vitamins B1, B9, B12, A, E and D, here the biggest risk of deficiency is especially for vitamin D
For gastric bypass:
- Gastric bypass is a dual-surgery surgery for obesity. The first restriction effect associated with a decrease in gastric volume and the second malabsorption effect with bypass of the small intestine. This malabsorption, very effective in weight loss, also leads to significant deficiencies in vitamins and minerals that need to be replenished for life with a sufficient daily allowance. Therefore, the consumption of vitamins after bypass remains essential throughout life and often requires taking several tablets.
- Vitamin B1, B9, B12, A, E and D deficiency, here the biggest risk of deficiency is especially for vitamin B12
