Acid reflux and nausea are often caused by a malfunctioning lower esophageal sphincter, which allows stomach acid to flow into the esophagus. Lifestyle factors such as eating before bed, smoking, and consuming certain foods and medications can also contribute to the problem. A hiatus hernia can also cause these symptoms.
When a person has acid reflux and nausea, the problem commonly stems from the lower esophageal sphincter, which is a ring of muscle that closes off the stomach from the esophagus after food moves from the esophagus into the stomach. If these muscles don’t work as well as they should, acid from the stomach can be allowed to flow up into the esophagus, causing pain and nausea. Sometimes, a hiatus hernia can also cause these symptoms. A host of other factors can contribute to their development, including eating a large meal right before bed, smoking, taking aspirin or ibuprofen, and being overweight or pregnant.
Acid reflux, also called heartburn, is an unpleasant condition in which acids back up from a person’s stomach and flow into the esophagus. Nausea is one of the symptoms of acid reflux; others include bloating, hiccups that last for an extended period, cough and hoarseness, belching, and a bitter taste in the mouth due to regurgitation of stomach contents. When a person has a chronic and severe case of acid reflux, they may also have blood in their vomit or stool.
Normally, an individual’s esophageal sphincter prevents acids from traveling backwards from the stomach into the esophagus, but this is not always the case. This ring of muscle should close soon after food has moved into the stomach. Sometimes, however, the esophageal sphincter stays open too long, doesn’t close completely, or opens when it shouldn’t. If so, a person may experience acid reflux.
Sometimes, the cause of the problem with the esophageal sphincter is a hiatus hernia. This is when the upper stomach and esophageal sphincter are pushed up through the natural hole in the diaphragm. The diaphragm usually helps keep the stomach out of the chest and helps keep the acid in the stomach. However, it is unable to do this when the stomach is on top of it.
A person’s lifestyle or the things they consume often also contribute to acid reflux and nausea. For example, when a person lies down immediately after eating, they may be more likely to experience these symptoms. Eating spicy and acidic foods, consuming fatty foods, and drinking alcoholic and caffeinated beverages can also contribute to the problem. Aspirin, some muscle relaxants, and some other types of medications can also contribute to acid reflux. Also, a person may be more likely to develop acid reflux and its symptoms if they are overweight or smoke. pregnancy may also be a risk factor.
