Selenium Recommendation After Bariatric Surgery

Plant foods are the major sources of selenium and it varies tremendously according to its concentrations in soil which varies regionally. Animals that eat grains or plants that were grown in selenium rich soil have higher levels of selenium in their muscle and is widely distributed in all tissues. Selenium is present in foods like brazil nuts, walnuts, almonds, peanuts, cashew nuts, pistachios, pine nuts, hazelnuts, sunflower seeds, grains (wheat germ, barley, brown rice, oats), fresh water and salt water fish (tuna, halibut, sardines, flounder, salmon), shellfish (oysters, mussels, shrimp, clams, scallops), meat (beef, lamb, pork, liver), poultry (chicken, turkey), eggs and mushroom (button, crimini, shiitake) [45].

A prospective pilot study (n=39) showed that RYGB and laparoscopic adjustable gastric banding (LAGB) procedures increase the risk for disturbances of selenium and GTP homeostasis and suggested that consideration of selenium supplementation at higher levels of current RDA (i.e. 55 mcg) during the first 3 months and perhaps longer may be needed [26].

However, there is insufficient evidence for routine selenium screening or supplementation but patients with malabsorptive bariatric surgeries who have unexplained anemia or fatigue, persistent diarrhea, cardiomyopathy or bone metabolic diseases, selenium levels should be checked.
