B12 After Sleeve Gastrectomy

B12 is the most commonly deficient vitamin after sleeve gastrectomy. The main reason for B12 deficiency after sleeve gastrectomy is the role of our stomach in the absorption of vitamin B12.

The release of the protein (intrinsic factor) involved in the absorption of vitamin B12 is controlled by cells in the stomach (gastric parietal cells).

Since there will be a decrease in these cells with the removed part of the stomach in sleeve gastrectomy surgery, the absorption of vitamin B12 decreases after sleeve gastrectomy surgery.

Many conditions such as forgetfulness, numbness in the hands and toes, and fatigue can be observed with B12 deficiency after sleeve gastrectomy. In order to continue comfortably and healthily after sleeve gastrectomy, you should definitely include foods with high B12 value in your diet.

Foods to be consumed after sleeve gastrectomy surgery

Foods of animal origin are the richest in B12.

For example:

• Liver and kidney
• Red meat
• Tuna fish
• Trout
• Salmon
• Egg
• Milk and dairy products
• Sardine
• Foods such as oysters are examples.
• There is also vitamin B12 in plant-based foods, but in low amounts.

In order to minimize B12 deficiency after sleeve gastrectomy surgery, it is necessary to continue with a more protein-intensive diet. In this case, since foods with high B12 value will generally be consumed, there is no rapid and serious decrease in vitamin B12 levels. Again, multi-vitamin supplements started after surgery can also reduce the levels of many vitamins such as vitamin B12.

Vitamin B12 levels are maintained through regular blood tests and supplements if necessary.

Regular vitamin B12 supplementation is required for individuals with gastric sleeve who are vegetarian or vegan.
