Heartburn and spiciness may be related to diet, pregnancy, gastric ulcer, gastritis and other reasons. 1. Diet: Eating spicy and irritating food or drinking alcohol for a long time stimulates the gastric mucosa, causing damage to the gastric mucosa, which is prone to stomach pain and leads to heartburn and hotness. 2. pregnancy: estrogen and progesterone levels increase during pregnancy, stimulating the secretion of gastric acid; the uterus enlarges after pregnancy, and the pressure in the abdominal cavity increases, leading to sphincter dysfunction, which makes it easy for acid reflux to occur, leading to heartburn and hot flashes. 3. Gastric ulcer: The gastric mucous membrane is damaged, resulting in ulcers on the inner wall of the stomach, which can cause heartburn and hotness with a burning sensation, loss of appetite and other symptoms. Typical abdominal pain caused by gastric ulcer is mainly manifested by abdominal pain, which can be slightly relieved after eating. Gastroscopy is needed for clarity. Patients with gastric ulcers need to use acid-suppressing drugs and mucosal protectants under the guidance of a doctor to assist treatment. 4. Gastritis: Inflammation of the gastric mucosa caused by bacterial infection, resulting in congestion and edema of the gastric mucosa, causing pain in the stomach, abdominal distension, nausea, loss of appetite, etc., causing heartburn. If you have heartburn, it is recommended that you go to the hospital in time for an examination to clarify the cause of the disease and treat the symptoms, so as to avoid affecting your health.
