Gastric cramps are a manifestation of the contraction of the gastric mucosa and lumen of the stomach afterwards. The patient may feel like something is pulling up the stomach and even have contraction-like pain, the same as colic, like wringing a towel. Stomach cramps are analyzed for diseases elsewhere besides gastrointestinal diseases. That is, diseases caused by the stomach, do not only look for the causes of the stomach, other causes are specifically as follows: 1, because stomach cramps are often related to heart disease, at first heart disease patients will feel stomach cramps, feel colic, in fact, for the patient, he is not quite clear what is colic, what is stabbing pain; 2, with the type of food has some relationship, such as eating cold food will cause cramps, that is, in cold weather drink some mineral water, may all feel pain; 3, some people riding electric bikes in winter will get cold and chill. Especially when riding electric bikes or bicycles at a faster speed, it can also cause transient spasms, where the patient shows a painful state and is in a bent posture; 4. Stomach spasms are also related to duodenal bulb ulcers, because the stomach acid will stimulate the gastric mucosa and cause local contraction after more acid. So stomach cramps, in addition to focusing on stomach diseases, should also be focused on other places, including mainly heart diseases. Because the stomach and the heart are neighbors, many heart diseases, including very serious myocardial infarction, also show symptoms of gastric cramps, sometimes as a first symptom. Therefore, it is most important for the patient or the gastroenterologist to identify whether it is a stomach disease or caused by a heart disease, which must be eliminated so that it can be handled more easily.
