Stomach pain and vomiting a lot of acid and bitter water may be due to gastroesophageal reflux disease, bile reflux gastritis, peptic ulcer and other diseases.
1. Gastroesophageal reflux disease (GERD): a chronic disease in which the lower esophageal sphincter relaxes due to a variety of causes, leading to the reflux of gastric contents. Typical symptoms of GERD are acid reflux, burning pain behind the sternum after eating, and sometimes accompanied by nausea and vomiting.
2. Bile reflux gastritis: it is a disease caused by the reflux of bile-containing duodenal contents into the stomach. The bile enters the stomach and violates the gastric mucosa, leading to gastric spasm, which triggers pain in the stomach, and also causes nausea and vomiting when there is an increase in the intragastric pressure, and the vomitus is bitter due to the presence of bile.
3. Peptic ulcer: it is a disease in which the gastric acid and pepsin in the gastric juice cause damage to the mucous membrane of the digestive tract; if the gastric acid secretion is excessive, it will cause nausea and vomiting of acid.
If the symptoms of stomach pain and vomiting a lot of acid and bitter water, it is recommended to consult a doctor in a timely manner, under the guidance of a professional doctor treatment and medication, so as not to delay the condition.
