How does gastric bypass surgery affect the digestion process?

During gastric bypass surgery, the surgeon creates a smaller stomach pouch. The surgeon then attaches a Y-shaped section of the small intestine directly to the pouch. This allows food to bypass a part of the small intestine, which normally absorbs calories and nutrients. Having a smaller stomach helps you feel fuller sooner and eat less food. Gastric bypass surgery also triggers powerful hormone changes that help you control hunger. After surgery, some of the nutrients that your body normally would absorb will be limited and you'll also eat less food overall. Taking vitamin and mineral supplements everyday can help prevent any nutritional deficiencies.

Although the procedure causes enormous weight loss, it also significantly affects the normal digestion process. Bypassing the first part of the intestine interferes with normal absorption of critical nutrients and causes complications related to vitamin and mineral deficiencies, like anemia (iron deficiency) and metabolic bone disease (calcium and vitamin D deficiency).
