Medications and supplements

Taking medications

Some medications may need to be changed to liquid or a crushable format and this will be reviewed with you prior to surgery so you may follow-up with your physician if any medication changes are required.  For gastric banding patients, most pills or capsules are small enough to pass through the new stomach pouch. Initially, for gastric bypass and sleeve patients, your doctor may suggest that medications be taken in liquid form or crushed. The Bariatric Center of Michigan staff will help you determine how to take the medications so they are absorbed properly. (Back to Top)

Medication changes

Your primary care provider will make determinations regarding your medications for blood pressure, diabetes, etc., as you lose weight and these conditions are improved. Some can be discontinued when the conditions for which they are taken improve or resolve after weight loss surgery. For medications that need to be continued, the vast majority can be swallowed, absorbed and work the same as before weight loss surgery. Usually no change in dose is required. (Back to Top)

Nutritional supplements

You will have to take a multivitamins. Depending on age, you may need to take an iron supplement. This is especially true for women that are still menstruating on a monthly basis. Many young women despite their weight are anemic (low blood count) prior to undergoing gastric bariatric surgery.  A calcium citrate supplement is also extremely important, especially in women.  A calcium citrate supplement should also contain Vitamin D, a necessary component for the absorption of calcium.

Dietary Information

Dietary restrictions following bariatric surgery

Following surgery, you will need to follow specific eating guidelines. Registered dietitians work directly with bariatric surgery patients to provide dietary education before and after surgery. Dietary guidelines will differ according to the type of surgery you have had.

Most surgeons recommend a period of four weeks or more without solid foods after surgery. A liquid diet, followed by semi-solid foods or pureed foods, may be recommended for a period of time until adequate healing has occurred. Your surgeon will provide you with specific dietary guidelines for the best post-surgical outcome.

A high water intake protects you and helps your body to rid itself of waste products efficiently, promoting better weight loss. If you feel a desire to eat between meals, it may be because you did not drink enough water. After the operation some patients will be quite fatigued. It is not uncommon that the cause is from dehydration. its very important to stay well hydrated. (Back to Top)

Answers to questions about general eating habits

Why can’t I eat red meat after surgery?

Red meats contain a high level of meat fibers making it difficult to break down with chewing. This can result in a blockage. (Back to Top)

Can I have milk products?

This varies among patients. Milk contains lactose (milk sugar), which is not well digested. This sugar passes through undigested until bacteria in the lower bowel act on it, producing gas. Depending on individual tolerance, some persons find even the smallest amount of milk can cause cramps, gas and diarrhea. Also, milk has a moderate amount of sugar that makes for high calorie intake.

What are the best choices of protein?

Chicken, turkey, lean fish, low-fat cheeses and cottage cheeses, seafood (not fried) and egg whites are recommended. (Back to Top)
