1. Supplement vitamins to ensure you are receiving nutrition. Keeping up a regimen of multivitamins will ensure you remain healthy while eating the reduced amounts of food post op. This will be something you will need to do for the rest of your life, so start as soon as possible and you will get into a routine of taking them.
2. Drink at least 1.5 to 2 litres of water every day. This can be hard because of the reduced stomach size. However, your body needs this water and without it you will most likely suffer complications such as hair loss, eyesight problems, dry skin, etc.
3. Stay away from anything high in sugar and fat. Foods high in sugar and fat are also very high in calories and you will be required to consume very few calories post-op. High sugar and fatty foods can also bring about dumping syndrome, which causes vomiting and abdominal cramps almost immediately after consuming.
4. Never drink large amounts before a meal. It is crucial that your stomach gets filled with nutrient-rich foods at meal time, not liquids. You should not drink anything for at least 40 minutes before a meal and 20-30 minutes after eating.
5. Never drink any alcoholic or carbonated drinks. Alcohol and soda are full of empty calories and will upset your stomach. They are also not recommended because of the way your new stomach and small intestine have been structured. Your doctor will explain in detail the consequences of drinking these items and the complications they can cause.
