But in people with a weak sphincter or too much pressure from the stomach, the sphincter opens, allowing stomach contents to back up into the delicate esophagus, causing burning pain. Not surprisingly, heartburn frequently follows a large meal, or even lighter meals if one lies down too soon afterward. The horizontal position makes it easy for acid reflux to occur. Certain foods are believed to weaken the sphincter, causing many people to have trouble after meals high in fat, or after consuming mint, chocolate, alcohol or coffee. Acidic foods such as citrus and tomatoes also are potential troublemakers.
Smokers also tend to have more problems with heartburn.
Fefer believes many patients with mild symptoms can control their heartburn by simply avoiding conditions likely to cause it. Avoid specific foods that trigger heartburn. Don't lie down for three to four hours after eating a meal. Occasional symptoms should be treated with medicines that neutralize stomach acid, says Fefer. These are available in tablet or liquid form.
