What Does a Gastroenterologist Do?

Your digestive system involves a lot of organs that work together to process food. Common annoyances like bloating or diarrhea are sometimes signs that something has gone wrong in that process. That’s when it’s time to see a gastroenterologist at Cochise Oncology!

What is Gastroenterology?

Gastroenterology is the branch of medicine that focuses on the digestive system and its disorders. This includes diagnosing, treating, and preventing diseases and conditions affecting the esophagus, stomach, small intestine, colon, rectum, pancreas, gallbladder, and liver. The digestive system plays a crucial role in the body’s overall health and well-being, as it is responsible for the breakdown, absorption, and elimination of food and waste. 

Gastrointestinal disorders can range from mild conditions like acid reflux and constipation to more serious conditions such as inflammatory bowel disease, ulcerative colitis, and cancer. Gastroenterologists are medical doctors who specialize in diagnosing and treating these disorders.

What Do Gastroenterologists Treat?

Gastroenterologists are highly trained in treating a wide range of gastrointestinal (GI) disorders that affect the esophagus, stomach, small and large intestines, rectum, liver, pancreas, and gallbladder. Some of the common GI disorders that gastroenterologists treat include:

  • Gastroesophageal reflux disease (GERD), or chronic acid reflux and heartburn.
  • Inflammatory bowel disease (IBD)
  • Irritable bowel syndrome (IBS)
  • Peptic ulcer disease
  • Pancreatitis
  • Hepatitis or inflammation of the liver

Gastroenterologists also perform endoscopies, colonoscopies, and imaging tests to diagnose and treat GI disorders. Overall, gastroenterology is a crucial field of medicine that helps improve patients’ digestive health and quality of life. That’s why Cochise Oncology offers gastroenterology in addition to our services in medical and radiation oncology.

Digestive Diagnostics in Gastroenterology 

Gastroenterologists use various diagnostic tools, including endoscopies and imaging tests, to identify and treat GI conditions. During your appointment, your gastroenterologist will ask questions about your symptoms, evaluate your medical history, and may perform a physical examination. This will help them determine what further testing is needed. 

We may test blood samples to check for things like anemia or fecal samples to assess the bacteria in your digestive system. Your gastroenterologist will use the results of these tests to determine your condition and create a treatment plan. Treatment options may include medication, lifestyle changes, or surgery, depending on the severity and type of the disorder.
