If you have symptoms of a digestive disorder, your primary care physician may refer you to a gastroenterologist for further evaluation and treatment. At United Medical, our gastroenterologists have experience in identifying many gastrointestinal (GI) problems, which can be very difficult to do given that symptoms are often intermittent and unpredictable. To aid in a diagnosis, our doctors may perform an abdominal ultrasound or endoscopic procedure, such as a gastroscopy or colonoscopy.

Some of the most common signs of a GI disorder include abdominal pain, bloating, and gas, rectal bleeding, irregular or altered bowel habits, and hemorrhoids.

Our gastroenterologists commonly diagnose and treat:

Diagnosing and Treating GI Disorders

An endoscopy is an examination of the organs in the body using an endoscope, a flexible tube with a camera on the end that can examine and investigate inside the organs for any problems or damage. At United Medical, we offer two endoscopic examinations: gastroscopy and colonoscopy.


Gastroscopy is an examination of the inside of the esophagus, stomach, and duodenum. It is performed by using an endoscope, a thin, flexible fiber-optic instrument that is passed through the mouth and allows the doctor to see whether there is any damage to the lining of the esophagus (gullet) or stomach, and whether there are any ulcers in the stomach or duodenum.

Gastroscopy is suggested in diagnosing and treating problems such as:

  • Abdominal pain
  • Bleeding from the digestive tract
  • Cancers of the stomach or esophagus
  • Esophageal strictures
  • Gastritis, or stomach inflammation
  • Hiatal hernia
  • Removal of swallowed objects
  • Treatment of the "ulcer bacteria"
  • Ulcers of the esophagus, stomach, or duodenum

Gastroscopy is painless and is usually done under a light sedative as an outpatient procedure. When sedation is used, you will still be conscious and aware throughout the procedure. A nurse will lay you on your left side and the endoscopist will gently place the endoscope into your mouth and ask you to swallow.


Colonoscopy is an examination of the colon and distal part of the small bowel. The procedure requires an endoscope, a flexible tube camera inserted through the anus. This allows the doctor to examine and look for any problems or damages.

Colonoscopy is suggested to diagnose and treat problems such as:

Once you schedule a colonoscopy, the doctor will instruct you to be on a strict diet one to two days prior to the procedure. You will be given a laxative and a powder/liquid beverage to cleanse and flush the colon of any solid matter. During the procedure you may be lightly sedated. The whole procedure begins from examining the function of the sphincter and using the endoscope to examine the rectum and colon.

Managing Symptoms with Diet and Lifestyle

Many GI conditions can be prevented or managed successfully with the right diet. Common guidelines for a healthier digestive system include eliminating red meat, saturated fats, processed foods, and preservatives from your diet, and eating more plant-based foods that are high in fiber, as well as fish and lean meats.

If you have been diagnosed with an allergy to gluten (wheat), dairy, or something else, you should change your diet to eliminate or reduce those foods. By doing so, you will feel better and see an improvement in your symptoms.

Unhealthy lifestyle habits, like smoking, too much stress, and not exercising can have a major impact on your digestive health. Try increasing your activity, stop smoking, and eat a balanced diet, and you will be well on your way to better health overall.
