What causes acid reflux 

There are many things that can cause acid reflux, such as eating certain foods, lying down after eating, and having a hiatal hernia to name a few. When you have acid reflux, the contents of your stomach come back up into your esophagus. This can cause heartburn, which is a burning sensation in your chest. If you have GERD, this can also damage your esophagus over time.

What is GERD (Gastroesophageal Reflux Disease)

GERD is a condition that occurs when stomach acid or other contents of the stomach flow back up into the esophagus repeatedly. This can cause heartburn, chest pain, and other symptoms. GERD is often treated with medication, and incline bed therapy (sleeping with your head raised) but some people may also need surgery.

What is heartburn

Heartburn is a symptom of acid reflux, which is when stomach acid rises up into the esophagus. The most common symptoms are a burning sensation in the chest or throat, nausea, and regurgitation. Heartburn can be treated with over-the-counter antacids, but if it persists, you should see a doctor.

Common symptoms of GERD

Heartburn, also called acid indigestion, is the most common symptom of GERD and usually feels like a burning sensation in the chest, behind the breastbone, or in the middle of the abdomen. The pain often rises in your throat and may include a sour taste.

Treatments for Each

Acid reflux can be treated with over-the-counter antacids or prescription medications. GERD may require prescription medications, such as proton pump inhibitors or H2 blockers. Heartburn can be treated with lifestyle changes, such as avoiding trigger foods and eating smaller meals and sleeping with your head raised. If lifestyle changes don't help, antacids or other medications may be necessary.
