A pain in the stomach is often referred to as colic, which is more common in daily life. The most common cause is gastritis and intestinal spasms due to unhygienic eating or large amounts of colder foods. If this is the cause, the patient can take appropriate antibiotics and spasm-relieving drugs, such as belladonna tablets. If the pain is accompanied by nausea, vomiting, bloating and diarrhea in addition to pain, it may be a lesion of other organs in the abdominal cavity. It is recommended to go to the hospital for a detailed examination in time to clarify the cause and treat the cause accordingly to avoid delaying the condition.
