I. Dietary principles
(A) Dietary progress and eating speed
1. Dietary progress should be made in progressive stages, in the following order.
Clear flow → liquid → soft → solid food
2.Eating speed should be slowed down, each meal eating time for half an hour.
3. Eat small amounts of food and chew slowly (at least 25 times) to prevent gastric outlet obstruction and vomiting.
(B) The appropriate intake of food and supplements
1.It is advisable to take small-sized food for three main meals every day, and take two snacks.
2. Drink at least 6-8 cups (1500-2000cc) of water daily to prevent dehydration and constipation.
3.Take daily multivitamins and minerals, and follow the doctor’s instructions to take them regularly.
(C) Food that should not be consumed
1.Avoid concentrated sweets (e.g. sugar, cola, cakes, ices, etc.), which may cause “dumping syndrome”.
2.Avoid foods high in oil, which can prevent vomiting and weight gain.
3.When eating, avoid drinking water and soup, and take in water between meals or 30-45 minutes after meals.
4.Ice water, coffee, tea, alcohol and other stimulants should not be consumed within three months after surgery.
(D) Other precautions
1.After surgery, the initial stomach can only hold a small amount of capacity, and finally only half a cup to a cup (120cc-240cc) of capacity. If the stomach feels uncomfortable and vomiting occurs, you should avoid eating again.
2.If maladjustment occurs in the food you eat, you can temporarily return to the food you ate in the previous stage, such as clear liquid or fluid or soft food. The period is about one week.
II. Principles of dietary progress
(A) Clear liquid diet
1. Food choices: plain water, filtered broth, sports drink (diluted 1:1 with water), filtered unsweetened juice (diluted 1:1 with water), honey water, and de-oiled chicken soup and fish soup after the third day.
