Gastric bypass, like any other surgery, has its risks and complications. The altering of the gastrointestinal tract during gastric bypass surgery results in reduced absorption of calcium, iron, and some vitamins. This can cause malnutrition.

Protein Deficiency

The American Society for Metabolic and Bariatric Surgery (ASMBS) lists the following as the signs and symptoms of protein deficiency after gastric bypass surgery:

  • Hair loss
  • Tiredness
  • Swollen legs

Diet for Gastric Bypass Prevent Deficiency

How to Overcome Nutritional Deficiency After Gastric Bypass

  • Make protein a priority by incorporating fish, dairy, legumes, and beans in the gastric bypass diet.
  • Do not skimp on fresh vegetables and fruits.
  • Make sure to follow your post-bariatric multivitamin regimen.
  • The dosage for B-complex, calcium, and iron should be higher than the usually recommended levels.
  • Make sure to have a heavy dosage of Vitamin B12 if taking it in the form of pills.
  • Have a citrated form of calcium to achieve its optimal absorption.
  • Iron should be taken along with Vitamin C for optimal absorption.
  • Never combine iron supplements with calcium, as the two taken together will try to outdo each other to get absorbed by the body.
