You will need to make sure you are getting enough protein, vitamins, and minerals while you are losing weight quickly. Eating mostly protein, fruits, vegetables, and whole grains will help your body get the nutrients it needs.
Protein may be the most important of these foods early after surgery. Your body needs protein to build muscles and other body tissues, and to heal well after surgery. Low-fat protein choices include skinless chicken, lean beef or pork, fish, whole eggs or egg whites, beans, and dairy products. These include low-fat or nonfat hard cheeses, cottage cheese, milk, and yogurt.
After gastric bypass surgery, your body will not absorb some important vitamins and minerals. You will need to take these vitamins and minerals for the rest of your life:
- Multivitamin with iron
- Vitamin B 12
- Calcium (1,200 mg per day) and vitamin D. Your body can absorb only about 500 mg of calcium at a time. Divide your calcium into 2 or 3 doses during the day. Calcium must be taken in the "citrate" form.
You may need to take other supplements also.
You will need to have regular checkups with your doctor to keep track of your weight and to make sure you are eating well. These visits are a good time to talk with your doctor about any problems you are having with your diet, or about other issues related to your surgery and recovery.
