Gastroenterologists are physicians who specialize in the digestive system, including the esophagus, stomach, and intestines. These doctors diagnose and treat conditions affecting these organs. They complete extensive training to manage a wide range of gastrointestinal disorders. Here is how these specialists diagnose and treat digestive disorders:
Imaging Diagnostics
Medical imaging enables doctors to visualize internal body structures. A specialist may use an abdominal ultrasound to view organs like the liver and gallbladder. This test uses sound waves to create images, so it is a non-invasive procedure. A CT scan provides detailed cross-sectional pictures, and it helps identify inflammation or structural problems. Other standard imaging tests include MRI scans, which produce highly detailed images of soft tissues without the use of radiation.
Endoscopy Procedures
Endoscopy allows for direct visual examination of the digestive tract. An endoscope is a thin, flexible tube with a camera. When the gastroenterologist needs to see the upper GI tract, they will perform an upper endoscopy. The scope enters through the mouth to inspect the esophagus, stomach, and small intestine. A colonoscopy examines the large intestine, and the scope is inserted through the rectum.
During these procedures, physicians may perform biopsies. A biopsy involves taking a small tissue sample for lab analysis. This helps diagnose conditions like celiac disease or cancer. Other actions are possible through the endoscope. A doctor might remove a polyp or stop bleeding. Patients typically receive sedation for comfort during the procedure.
Medication Management
Doctors may prescribe medications to manage digestive disorders. These drugs work in various ways to control symptoms. Some drugs are designed to reduce stomach acid production, and they are used for gastroesophageal reflux disease (GERD). The medication gives the esophagus time to heal, while it also relieves heartburn. Other medications target inflammation within the digestive tract.
Different conditions require specific drug therapies. For inflammatory bowel disease (IBD), doctors might prescribe aminosalicylates or biologics. These drugs help reduce intestinal inflammation. For infections, antibiotics are the standard treatment. A specialist will select a medication based on the specific diagnosis and the patient’s medical condition. The goal is to manage the condition effectively. The medication plan may also involve:
- Antidiarrheals
- Laxatives for constipation
- Antispasmodics to relieve cramping
Surgery Procedures
Sometimes, surgery is a necessary treatment option. A surgeon may perform a procedure when other treatments have not worked. Removing a diseased part of the intestine may be required for severe Crohn’s disease. The operation aims to resolve the immediate problem, and it can provide long-term relief from symptoms.
An appendectomy is the removal of the appendix, and a cholecystectomy is the removal of the gallbladder. Both are standard procedures for inflammation or infection. Laparoscopic techniques may be used for these surgeries. This minimally invasive approach involves small incisions, which allows for a quicker recovery.
Specific procedures correct structural problems in the digestive tract. Fundoplication is a surgery that reinforces the valve between the esophagus and stomach. It is a treatment for severe GERD. Surgeons can also repair hernias or remove tumors found in the digestive system. Surgery is a significant step, and it is reserved for specific medical situations.
