Acid reflux, a heart attack and gallstones are three conditions that cause belching and chest pain together, according to Healthline. A heart attack typically causes other symptoms, such as shortness of breath and dizziness in conjunction with chest pain and vomiting, and it requires immediate medical attention.
Heart attacks occur when a blood clot in a coronary artery leads to a blockage, notes the Cleveland Clinic. When a blockage happens, the heart muscle does not receive enough oxygen and becomes damaged. A major cause of heart attacks is coronary artery disease, which is due to the buildup of fatty deposits in artery walls. The buildup of fatty deposits narrows arteries, leading to reduced blood flow to the heart muscle and blood clot formation.
Acid reflux occurs when stomach acids leak into the esophagus, explains the Cleveland Clinic. Symptoms of acid reflux include trouble swallowing, chest pain, bad breath and acid regurgitation. If the symptoms of acid reflux occur more than twice a week, then the cause of the condition may be due to gastroesophageal reflux disease, which leads to serious complications. Doctors do not know the exact cause of GERD, but factors that contribute to its development include a hiatal hernia, smoking, alcohol use and pregnancy.
Gallstones form in the gallbladder as hard deposits, and they can be made of cholesterol or bilirubin, according to MedlinePlus. Factors that make patients more at risk for developing gallstones include a genetic predisposition, diabetes, liver cirrhosis and rapid weight loss. Patients with gallstones experience pain in the upper abdomen, fever, nausea, vomiting and clay-colored stools.
