Digestive Health at Ascension St. Vincent involves gastroenterologists and nurses specializing in endoscopic and gastroenterology procedures, including colonoscopy. These specialists treat all types of upper and lower GI conditions including colorectal cancer. If you are over 50 years of age, ask your primary care doctor about having a baseline colonoscopy. This minimally invasive procedure can significantly reduce the risk of developing colon cancer.

Heartburn, acid reflux and GERD

Chronic acid reflux disease is also known as gastroesophageal reflux disease (GERD). If you have heartburn twice a week or more, you may have GERD. Heartburn is the most common symptom, but you may also experience:

  • Hoarseness or sore throat
  • Frequent swallowing
  • Asthma or asthma-like symptoms
  • Pain or discomfort in the chest
  • Sleep disruption (unable to sleep lying down)
  • Bloating
  • Excessive clearing of the throat
  • Persistent cough
  • Burning in the mouth or throat
  • Intolerance of certain foods
  • Dental erosions or therapy-resistant gum disease or inflammation

Normally, after swallowing, a valve between the esophagus and stomach opens to allow food to pass, then it closes to prevent stomach contents from “refluxing” back into the esophagus, causing a burning sensation in the chest. For people who suffer from GERD, the valve is dysfunctional and unable to prevent acid from refluxing into the esophagus.
