Supplementation standardized patients after surgery consists of a formulation containing various nutrients needed by the body

Survey of patients who underwent bariatric surgery at the Hospital das Clinicas (HC), Unicamp, shows that in 88% of the 36 evaluated protein intake was lower than recommended. Even consuming a standardized supplementation, 61% of them remained zinc deficiency in the body after the procedure and six months, preoperatively, 55% had deficient due to poor nutrition.

These results were presented by nutritionist Renata Cristina Gobato, the Faculty of Medical Sciences (FCM). The weight loss is important to prevent the risk of developing several diseases. On the other hand, we must be aware of nutritional issues for boards to avoid deficiencies. Zinc, for example, is an important nutritional component, as part of the entire metabolism, with important antioxidant function, immune regulating appetite and taste.

The study included the analysis of zinc and copper, as surgical technique that involves restriction of stomach and intestinal bypass used in Unicamp restricts uptake of micronutrients in the body. Rich sources of these micronutrients (beef, oysters, whole grains, nuts for zinc and liver, whole grains, nuts and chocolate for copper) are not recommended after surgery.

Renata insists that food consumption before surgery should also be reinforced because the study disability existed. In the case of copper, it explains that the results were not as significant as in the case of zinc. For the survey, only 8% of patients had postoperative disability.

Supplementation standardized for patients following surgery consists of a formulation containing various nutrients needed by the body, including zinc oxide. However, if before the procedure had the deficiency, the zinc oxide would not be the most appropriate way to reach the normal levels required.

Adequate zinc intake would be between eight and 11 milligrams per day for women and men respectively, so, according to the nutritionist, the ideal would be that supplementation with zinc chelate specific, but it is necessary to buy this supplement separately, as available forms do not show this chemical form of the element. According to nutritionists, it is not feasible for the profile of patients who are treated at HC.
