Nutritional guidance post-surgery

diet after bariatric surgeryAs the obesity levels remain unabated, the popularity for bariatric surgery also finds new heights. To optimize long-term health after bariatric surgery, it is essential to recognize symptoms of nutritional deficiency, and get a nutrition rich diet plan with supplements (if needed) for any deficit of nutrients that may come up post-surgery.

A post bariatric surgery diet specifies what type and how much food you can eat in each meal. Closely following your diet can help you lose weight safely. “We would advise a daily intake of macronutrients (carbohydrate, protein, fat) post-surgery but the micronutrient (iron, iodine, manganese, zinc etc.,) intake is what remains at a worryingly low-level and it is essential that nutritional guidance is provided to patients following their bariatric surgery,” said Dr. Nandakishore Dukkipati, Chief Surgeon at LivLife Hospitals.

Dr. Dukkipati believes that nutritional deficiency is sadly becoming a recurrent issue with many bariatric patients. His assumptions are supported by the researchers from Leuven University College, University Hospitals, Belgium who have drawn to the conclusion that bariatric surgery is associated with nutritional deficiencies too. Their study sought to evaluate the dietary intake of macro- and micronutrients in patients before and after Roux-en-Y gastric bypass (RYGB).

It was found to have decreased phenomenally for patients on their first month after RYGB. At three months post-surgery, the intake of macronutrient increases (Table 1) but the micronutrient intake remains low (Table 2).The results are as follows:-
