Nutritional deficiencies that may develop after partial removal of the stomach include deficiencies in vitamin B12, iron, calcium, and fat-soluble vitamins (A, D, E, K) due to malabsorption. The surgery can lead to decreased gastric surface area and alterations in digestion and absorption processes.

After partial gastrectomy, patients may experience malabsorption syndromes that can result in specific nutritional deficiencies. The removal of part of the stomach can reduce the absorption of vitamin B12, which is dependent on intrinsic factor produced in the stomach. Additionally, deficiencies in iron and calcium can occur due to reduced gastric acid secretion, which is necessary for their absorption. Fat-soluble vitamins (A, D, E, K) may also be poorly absorbed due to bile salt deficiencies that can arise from alterations in the digestive process following surgery.
