Gastroesophageal reflux is a condition in which the acidic contents of the stomach flow back into the esophagus. According to the National Digestive Diseases Information Clearinghouse, if reflux is persistent, occurring more than twice in a week, it is a sign of gastroesophageal reflux disease, or GERD. One of the most effective medicines used to treat GERD contains calcium.
Causes of Acid Reflux
The main cause of gastroesophageal reflux is weakness of the lower esophageal sphincter. This round mass of muscle opens to allow food into the stomach and closes tightly to prevent acid from flowing back out. When this muscle weakens, acid from the stomach flows unobstructed into the esophagus, leading to the symptoms of gastroesophageal reflux disease. The contents of diets can also predispose you to reflux. Acidic foods such as citrus fruits, spicy foods and caffeine-containing beverages and medicines can increase the chances of developing reflux.
Symptoms of Acid Reflux
According to the University of Maryland Medical Center, the main symptom of gastroesophageal reflux disease is heartburn. This is a burning sensation that goes from the abdomen up to the chest. Other symptoms of reflux include dyspepsia, a feeling of fullness accompanied by nausea, and regurgitation, in which the acid reaches the back of the throat.
Calcium antacids
Calcium is one of the components of over-the-counter antacid medications. Antacids work by neutralizing the acidity of the stomach contents. Even though they do not stop reflux, it makes the stomach contents less acidic, therefore preventing some of the harmful effect and the symptoms of reflux disease. The most common form of calcium for reflux is calcium carbonate. It may come in tablets, chewable tables, liquid form or in capsules.
Side Effects and Precautions
If you have a kidney condition, you should not take calcium-containing antacids without first consulting your doctor. Also, you should avoid these medicines if you have had an allergic reaction to them. According to MedlinePlus, calcium carbonate can decrease the effectiveness of certain medications, including digoxin, a heart medicine, and dilantin, a seizure medicine. You should not take calcium antacids within an hour or two of taking these medicines. Side effects of calcium carbonate include upset stomach, vomiting, constipation and dry mouth.
