You should not eat solid foods for at least three months following gastric sleeve surgery. If you do this, the surgery’s success rate will decrease. You must be fed while under the care of a doctor. Remember that gastric sleeve surgery is ineffective on its own. The nutrition program following the surgery is very important. The purposes of diet and avoiding solid foods are to reduce liver fat and therefore its size due to the fact that the first pounds given are from the liver. In this way, the work of surgeons becomes seriously easier and thus the operation time is shortened. In addition, possible complications are minimum. Each patient’s diet is different. You should only eat foods that are on the doctor’s diet plan. Otherwise, you may be unable to lose weight following surgery and may even gain weight.
