The new 2017 edition of the Type 2 Diabetes Prevention and Control Guidelines are very clear on postoperative management of metabolic surgery for diabetes, which is critical for recovery, health, and long-term outcomes. Let’s take a look at what the guidelines have to offer in terms of criteria, and then my opinion. 1. Restrict total calories and use a gradual phase diet with clear liquids for about 1 week and liquids, soft, and solid foods for about 1 month. Slow down the speed of eating, about 30 min per meal; eat less and more, chew and swallow slowly to prevent gastric outlet obstruction and vomiting; achieve the daily recommended total calories in a gradual manner. 2. Postoperative dietary contraindications. Avoid concentrated sweets, including drinks and snacks, to prevent dumping syndrome; avoid fried and indigestible foods; avoid soup and water during meals, and may ingest soup between 2 meals or 45 min after meals; avoid intake of iced water, coffee, tea, alcohol and other stimulants within 3 months. 3.Ensure protein intake, at least 60-120 g protein per day, especially high-quality protein, such as fish, chicken, pork, sheep, cattle and other meat, tofu, soybean flower, milk (low-fat or non-fat), eggs, etc. 4.Replenish water, drink 1,500-2,000 ml of water daily. 5.Supplement vitamins and micronutrients, it is recommended to supplement vitamin D 3,000 U, calcium 1,200-1,500 mg, iron 150-200 mg, folic acid 400 μg, vitamin B12 1,000 mg, and other micronutrients daily. 6. Adhere to exercise after surgery to improve weight loss efficacy and health-related quality of life. Exercise at least 30 min per day. My opinion is that the guidelines are only for us to do as the general standard and direction on the line, in the actual clinical practice or different cases, we also need to develop individualized management plans for different patients, multi-departmental collaboration, and not all of them can adopt the same standard. It is important to have post-operative follow-up, where the physician actively pays attention to the patient’s recovery and makes appropriate adjustments when appropriate.
