If you are a post-operative patient who has undergone bariatric or diabetic surgery, the following advice is important to read carefully as you return to a healthy life and prevent long-term complications in the future. First, it is important to maintain long-term contact with your primary care physician after surgery. It is important to have at least three outpatient follow-up visits during the first year after surgery, as well as additional follow-up visits by phone or other means. These visits will include blood glucose, glycosylated hemoglobin, insulin, C-peptide, as well as your weight, nutritional status, and mental status. After that, you are expected to visit the hospital where you had your surgery once a year for a complete checkup. The purpose of the follow-up visit is to facilitate the doctor to grasp the control of your obesity, whether you still need diet or medication, and to monitor whether there are any complications related to obesity and whether there is any improvement after the surgery. At the same time, to monitor whether there are any complications of surgery and whether there are any deficiencies of nutrients, vitamins or minerals, so that timely adjustments in treatment can be made. Secondly, it is important for patients undergoing surgery to recognize that dietary guidance is a crucial part of ensuring the effectiveness of surgical treatment, avoiding long-term postoperative complications, and improving various postoperative discomforts for patients. The aim is to form a new diet to promote and maintain improved glucose metabolism while replenishing essential nutrients and avoiding discomfort. The main measures are to drink sufficient amount of fluids, eat enough protein, and supplement essential vitamins and minerals. (1) Eat a low-sugar, low-fat, low-calorie diet; (2) Avoid overeating; (3) Eat slowly, about 20-30 minutes per meal; (4) Chew and swallow slowly, avoiding foods that are too hard or large; (5) Eat protein-rich foods first, avoiding high-calorie foods; (6) Depending on the type of surgery, some require daily supplementation of essential vitamins and, according to instructions, minerals; (7) Ensure that essential vitamins and minerals are supplemented. (7) Ensure adequate daily fluid intake and avoid carbonated beverages; (8) Avoid spicy and stimulating foods such as chili peppers, tea, coffee, tobacco and alcohol. Third, for some discomfort, necessary medication and psychological counseling are also required. If you have long-term heartburn and acid reflux, you can be given appropriate drugs to inhibit stomach acid and protect the gastric mucosa; if vomiting occurs after eating, then first you should reflect on whether you eat too fast, too much, or eat some indigestible food. In addition, some patients may have an increased number of bowel movements or more gas after surgery, which is a normal condition after the reconstruction of the digestive tract after gastric diversion surgery. With the extension of time, this situation will slowly ease in some patients and will not affect your life too much. Fourthly, you need to pay attention to vitamin supplementation. Due to the reconstruction of the digestive tract, the absorption of certain vitamins may be reduced. Although there are few reports of these complications in China, we recommend that you take the necessary supplements in order to prevent the resulting adverse consequences. In the early postoperative period, you can start supplementing with SunCure tablets (the main ingredient is a multivitamin and some trace elements). This medication is already consumed by many normal people as a health supplement, so it is generally not harmful to your health. After this, you will need to take Vit B12, iron, Vit B complex, folic acid and calcium according to your doctor’s test results. Fifth, if you need to have abdominal surgery in the future due to some other medical condition, we strongly recommend that your surgeon contact us before the surgery. This is because for some doctors, it is very important to communicate with us before surgery in order to avoid some unnecessary side effects. It is important to emphasize that metabolic surgery is a double-edged sword and there is a price to be paid for the benefits you receive. But overall, the benefits of sleeve gastrectomy far outweigh the harms for obese patients, and as long as you follow the post-surgical instructions and stay in close contact with your surgeon, we are confident that you will have a satisfactory outcome.
