Information for Patients
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.

Small Intestine Disorders
Your small intestine is the longest part of your digestive system - about twenty feet long! It connects your stomach to your large intestine (or colon) and folds many times to fit inside your abdomen. Your small intestine does most of the digesting of the foods you eat. It has three areas called the duodenum, the ileum, and the jejunum.
Problems with the small intestine can include:
- Celiac disease
- Crohn's disease
- Intestinal cancer
- Intestinal obstruction
- Irritable bowel syndrome
- Ulcers, such as peptic ulcer
Treatment of disorders of the small intestine depends on the cause.
