What causes acid reflux disease?

One common cause of acid reflux disease is a stomach abnormality called a hiatal hernia. This occurs when the upper part of the stomach and LES move above the diaphragm, a muscle that separates your stomach from your chest. Normally, the diaphragm helps keep acid in our stomach. But if you have a hiatal hernia, acid can move up into your esophagus and cause symptoms of acid reflux disease.

These are other common risk factors for acid reflux disease:

• Eating large meals or lying down right after a meal
• Being overweight or obese
• Eating a heavy meal and lying on your back or bending over at the waist
• Snacking close to bedtime
• Eating certain foods, such as citrus, tomato, chocolate, mint, garlic, onions, or spicy or fatty foods
• Drinking certain beverages, such as alcohol, carbonated drinks, coffee, or tea
• Smoking
• Being pregnant
• Taking aspirin, ibuprofen, certain muscle relaxers, or blood pressure medications

What Are the Symptoms of Acid Reflux Disease?

Common symptoms of acid reflux are:

• Heartburn: a burning pain or discomfort that may move from your stomach to your abdomen or chest, or even up into your throat
• Regurgitation: a sour or bitter-tasting acid backing up into your throat or mouth

Other symptoms of acid reflux disease include:

• Bloating
• Bloody or black stools or bloody vomiting
• Burping
• Dysphagia — a narrowing of your esophagus, which creates the sensation of food being stuck in your throat
• Hiccups that don’t let up
• Nausea
• Weight loss for no known reason
• Wheezing, dry cough, hoarseness, or chronic sore throat
