With the popularity of bariatric surgery, this effective treatment for obesity and its complications has become a new treatment option for many morbidly obese and diabetic patients, and sleeve gastrectomy is one of the more common ones. A sleeve gastrectomy is a procedure in which a portion of the stomach is removed to reduce the amount of food eaten by the patient. This procedure generally involves the removal of a large portion of the stomach along the long axis of the stomach, leaving a residual volume of about 60-80 ml, while preserving 2-6 cm of the sinus above the pylorus in the direction of the greater curvature of the stomach. Relatively speaking, sleeve gastrectomy has fewer complications and minimal impact on life, and some hospitals can also perform single-port sleeve gastrectomy, so this procedure has become the choice of many people. However, some patients who have undergone the surgery also find that after the sleeve gastrectomy, although the amount of food they eat each time is greatly reduced, they are also easily hungry, which makes them a little worried. It is normal to be hungry easily after sleeve gastrectomy. After sleeve gastrectomy, the patient’s stomach volume has become smaller, and the amount of food eaten each time is much less than before, and with the change of hormone secretion in the stomach, the gastric emptying speed is faster than before the surgery, so it is easier to be hungry. This change is actually beneficial to patients, because eating too little at a time, if they still eat only three times a day, this will prevent those who consume too much energy from getting enough replenishment, which will easily cause malnutrition. The accelerated gastric emptying rate can increase the number of times you eat, thus replenishing energy. For people with less physical exertion, consider eating some low-calorie but easy-to-fill snacks in between meals, which can also effectively prevent regained weight.
