Acid reflux how does it happen

A hole in the diaphragm allows the upper part of the stomach to enter the chest cavity, sometimes leading to GERD. Other risk factors are more easily controlled:. A recent study suggests that dietary choices may be as effective as using proton pump inhibitors PPIs in treating acid reflux.

PPIs and H2 blockers decrease acid production and reduce the potential for damage caused by acid reflux. These medications are generally safe and effective, but like any prescription drug, they are not appropriate for all people with reflux disease and can cause side effects. For instance, they can cause problems absorbing nutrients. This can lead to malnutrition. For people who experience heartburn or indigestion infrequently, perhaps in association with occasional food and drink triggers, OTC treatments to reduce the acidity of the stomach contents are available.

These liquid and tablet formulations are called antacids, and there are dozens of brands available, all with similar effectiveness.

They may not work for everyone, and any need for regular use should be discussed with a doctor. They contain chemical compounds such as calcium carbonate, sodium bicarbonate, aluminum, and magnesium hydroxide. They can also inhibit nutrient absorption, leading to deficiencies over time. Gaviscon is probably the best-known heartburn therapy. It has a different mode of action than antacid drugs. Alginate drugs such as Gaviscon vary slightly in composition, but they usually contain an antacid.

The alginic acid works by creating a mechanical barrier against the stomach acid, forming a foamy gel that sits at the top of the gastric pool itself. Any reflux is then relatively harmless as it consists of alginic acid and not damaging stomach acid. If you want to buy Gaviscon, then there is an excellent selection available online. If GERD is severe and unresponsive to medical treatment, a surgical intervention known as fundoplication may be needed. Acid reflux usually produces heartburn, whether it is due to a single episode of overeating or persistent GERD.

Heartburn is an uncomfortable burning sensation that occurs in the esophagus and is felt behind the breastbone area. It tends to get worse when lying down or bending over. It can last for several hours and often worsens after eating food. The pain of heartburn may move up toward the neck and throat. Stomach fluid can reach the back of the throat in some cases, producing a bitter or sour taste.

Without treatment, GERD can lead to serious complications in the long term, including an increased risk of cancer. Show references Kahrilas PJ. Clinical manifestations and diagnosis of gastroesophageal reflux in adults. Accessed Jan. Feldman M, et al. Gastroesophageal reflux disease.
