Information for Patients


After Surgery

After any operation, you'll have some side effects. There is usually some pain with surgery. There may also be swelling and soreness around the area that the surgeon cut. Your surgeon can tell you which side effects to expect.

There can also be complications. These are unplanned events linked to the operation. Some complications are infection, too much bleeding, reaction to anesthesia, or accidental injury. Some people have a greater risk of complications because of other medical conditions.

Your surgeon can tell you how you might feel and what you will be able to do - or not do - the first few days, weeks, or months after surgery. Some other questions to ask are

  • How long you will be in the hospital
  • What kind of supplies, equipment, and help you might need when you go home
  • When you can go back to work
  • When it is ok to start exercising again
  • Are they any other restrictions in your activities

Following your surgeon's advice can help you recover as soon as possible.

Malabsorption Syndromes

Your small intestine does most of the digesting of the foods you eat. If you have a malabsorption syndrome, your small intestine cannot absorb nutrients from foods.

Causes of malabsorption syndromes include

  • Celiac disease
  • Lactose intolerance
  • Short bowel syndrome. This happens after surgery to remove half or more of the small intestine. You might need the surgery if you have a problem with the small intestine from a disease, injury, or birth defect.
  • Whipple disease, a rare bacterial infection
  • Genetic diseases
  • Certain medicines

Symptoms of different malabsorption syndromes can vary. They often include chronic diarrhea, abnormal stools, weight loss, and gas. Your doctor may use lab, imaging, or other tests to make a diagnosis.

Treatment of malabsorption syndromes depends on the cause.
