Stomach pain and hiccups are considered to be related to gastric insufficiency caused by gastritis, peptic ulcer and other diseases, stomach cramps and so on. 1. Gastric insufficiency: If the symptoms of stomach pain are mainly bloating, it is mostly considered to be caused by gastritis, peptic ulcer and other diseases caused by gastric insufficiency. When gastric insufficiency, too much food and gas will accumulate in the stomach, resulting in increased pressure in the stomach, and this pressure change will stimulate the gastric mucosa and sensitive nerves in the stomach, thus triggering gastroparesis; the gas in the stomach is restricted in its downward movement, and it is easy to go upward to the throat area and cause hiccups. 2. Stomach cramp: If the stomach pain is paroxysmal, it is considered to be stomach cramp, which is caused by excessive contraction of the smooth muscle of the stomach due to diet and other factors. When the smooth muscle of the stomach contracts in the opposite direction, it will push the gas in the stomach upward and cause hiccups. If you have the above symptoms, you should consult a gastroenterologist in time, who will determine the cause of the disease based on the specific symptoms at the onset of the disease and the results of the appropriate tests.
