Digestive diseases

Digestive diseases are disorders of the digestive tract, which is sometimes called the gastrointestinal (GI) tract.

In digestion, food and drink are broken down into small parts (called nutrients) that the body can absorb and use as energy and building blocks for cells.

The digestive tract is made up of the esophagus (food tube), stomach, large and small intestines, liver, pancreas, and the gallbladder.

A digestive disease is any health problem that occurs in the digestive tract. Conditions may range from mild to serious. Some common problems include heartburn, cancer, irritable bowel syndrome, and lactose intolerance.

Tests for digestive problems can include colonoscopy, upper GI endoscopy, capsule endoscopy, endoscopic retrograde cholangiopancreatography (ERCP), and endoscopic ultrasound.

Many surgical procedures are performed on the digestive tract. These include procedures done using endoscopy, laparoscopy, and open surgery. Organ transplants can be performed on the liver, pancreas, and small intestine.

Many health care providers can help diagnose and treat digestive problems. A gastroenterologist is a physician specialist who has received extra training in the diagnosis and treatment of the digestive disorders. Other providers involved in the treatment of digestive diseases include:

  • Nurse practitioners (NPs) or physician assistants (PAs)
  • Nutritionists or dietitians
