What Is Gastroenterology?

Your gastrointestinal system is comprised of a collection of organs responsible for providing you with energy. Together, the following organs move food through your body, digest it, absorb nutrients, and remove the remaining waste:

  • Pharynx
  • Esophagus
  • Stomach
  • Liver
  • Intestines
  • Gallbladder
  • Pancreas
  • Rectum

Classifying Gastrointestinal Disorders

Gastrointestinal system disorders comprise everything from mild heartburn to hepatitis C. Researchers break them down into two types; functional and structural gastrointestinal disorders. Functional gastrointestinal disorders (FGD) are unrelated to a structural or tissue anomaly. In other words, the GI tract looks normal, but the problem stems from its functionality. Meanwhile, structural gastrointestinal disorders (SGD) are caused by a visible abnormality in the system’s structure or tissues. Symptoms of GI system disorders include:

  • Nausea
  • Vomiting
  • Gas and bloating
  • Stomach and/or pains
  • Constipation
  • Diarrhea
  • Difficulty swallowing
  • Unexplained bleeding

Gastrointestinal Conditions We Treat

Led by the expertise and experience of Dr. Peter Heit, M.D., we offer comprehensive evaluations and effective treatment options for a variety of digestive disorders. Common conditions we diagnose and address include the following and more:

  • Abdominal pain: Pain in your abdomen can be caused by a variety of conditions, including constipation, food allergies, food poisoning, viruses, and more.
  • Acid reflux: This common issue brings on burning chest pain, or heartburn, which is the result of stomach acid flowing upward into the esophagus.
  • Celiac disease: This disorder is caused by an abnormal immune response that damages the small intestine in response to the consumption of gluten.
  • Crohn’s disease: This is an inflammatory bowel disease that inflames the digestive tract, leading to pain, fatigue, weight loss, and symptoms of malnutrition.
  • Ulcerative colitis: This illness develops slowly over time and causes inflammation and long-lasting ulcers or sores in the digestive tract.
  • Gastroesophageal reflux disease: Also known as GERD, this is a chronic form of acid reflux.
  • Irritable bowel syndrome: Also called IBS, this common disorder causes weight loss, diarrhea, rectal bleeding, iron deficiencies, unexplained vomiting, and discomfort.
  • Lactose intolerance: This disorder is the result of a deficiency in the lactase enzyme and causes an inability to digest the lactose found in dairy products.
