GERD, also known as acid reflux, is an acronym that stands for gastroesophageal reflux disease. It is a chronic illness that affects 5-7% of the world population and is associated with serious medical complications if untreated. GERD is the 3rd most common gastrointestinal disorder in the U.S. Most patients with GERD also experience nighttime heartburn, which is more bothersome. And according to the 2001 NSF Sleep in America poll, adults in America who experience nighttime heartburn are more likely to report having symptoms of sleep problems/disorders such as insomnia, sleep apnea , daytime sleepiness and restless legs syndrome than those who don’t have nighttime heartburn.
GERD describes a backflow of acid from the stomach into the esophagus. Most patients with GERD experience an increase in the severity of symptoms (usually heartburn or coughing and choking) while sleeping or attempting to sleep. If the acid backs up as far as the throat and larynx, the sleeper will wake up coughing and choking. If the acid only backs up as far as the esophagus the symptom is usually experienced as heartburn.
Most people refer to GERD as heartburn, although you can have it without heartburn. Sometimes GERD can cause serious complications including inflammation of the esophagus from stomach acid that causes bleeding or ulcers. In a relatively small number of patients, GERD has been reported to result in a condition called Barrett's esophagus, which over time can lead to cancer. Also, studies have shown that asthma, chronic cough, and pulmonary fibrosis may be aggravated or even caused by GERD.
GERD is common and may be frequently overlooked in children. It can cause repeated vomiting, coughing, and other respiratory problems. Talk to your child's doctor if the problem occurs regularly and causes discomfort.
