Acid reflux and heartburn have similarities. Heartburn may be part of acid reflux, which may require medical care. Occasional heartburn can be an inconvenience, a painful one in which you have a burning pain in your chest that may occur after eating or at night. You may also feel pain when lying down or bending over. The symptoms may go away with antacids. If the heartburn happens more than twice a week, you might have acid reflux disease. Acid reflux can be treated with over-the-counter or prescription medication. If the symptoms persist, further treatment may be necessary.
Food Pathway
Heartburn and acid reflux occur when the lower esophageal sphincter does not close properly when food passes through, the American Academy of Family Physicians explains. When it does not close all the way, stomach acid gets through the opening and moves back up into the esophagus, causing the reflux. The stomach acid irritates the esophagus, resulting in heartburn.
Misconceptions
Some foods can cause heartburn and acid reflux. It often depends on the individual, but common offenders include fatty and fried foods, tomato-based sauces, onions, caffeine, alcohol, carbonated drinks, chocolate and some citrus fruits. However, a study at Stanford University, published in the May 8, 2006 issue of "Archives of Internal Medicine," found no evidence that spicy foods, coffee, chocolate and other foods caused heartburn. Researchers advised losing weight if you are overweight and raising the head of your bed to cut down on heartburn during the night.
Prevention
Heartburn may also depend on individuals and the way they eat. You should try to lose weight, eat smaller, frequent meals and avoid lying down for at least three hours after eating, advises the National Digestive Diseases Information Clearinghouse. Smoking may also contribute to heartburn.
Hiatal Hernia
Hiatal hernias can cause acid reflux. This happens when part of the stomach pushes up through the diaphragm and into the chest. A doctor may diagnose this problem if acid reflux persists despite medication.
Medications
Antacid tablets and liquids can often relieve symptoms quickly. More powerful over-the-counter products include H2 blockers, which are acid reducers that do not work right away, but last longer by reducing acid production. Proton pump inhibitors, usually available by prescription, are stronger and more effective than H2 blockers.
Surgical Option
If symptoms continue after taking these medications and making dietary changes, visit a doctor. Surgery is an option for severe acid reflux that can damage the esophagus or stomach lining. Surgeons may strengthen the esophageal sphincter to prevent acid reflux.
