Information for Patients
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.

Wounds and Injuries
An injury is damage to your body. It is a general term that refers to harm caused by accidents, falls, hits, weapons, and more. In the U.S., millions of people injure themselves every year. These injuries range from minor to life-threatening. Injuries can happen at work or play, indoors or outdoors, driving a car, or walking across the street.
Wounds are injuries that break the skin or other body tissues. They include cuts, scrapes, scratches, and punctured skin. They often happen because of an accident, but surgery, sutures, and stitches also cause wounds. Minor wounds usually aren't serious, but it is important to clean them. Serious and infected wounds may require first aid followed by a visit to your doctor. You should also seek attention if the wound is deep, you cannot close it yourself, you cannot stop the bleeding or get the dirt out, or it does not heal.
Other common types of injuries include
- Animal bites
- Electrical injuries
- Fractures (broken bones)
- Sprains and strains
