Gastric cramps after eating may be caused by physiological factors such as improper diet, or pathological factors such as gastric diseases and food intolerance. 1. Physiological factors: If the patient eats too much cold, spicy and other stimulating food or fried and other indigestible food, it will stimulate the gastrointestinal tract, leading to gastrointestinal spasm and gastric cramps, which will lead to gastric cramps after eating. Certain bad eating habits, such as overeating, eating too fast, and exercising strenuously for a short period of time after meals, can also lead to stomach cramps after eating. 2. Stomach diseases: such as peptic ulcer, gastroenteritis, gastric cancer and other diseases, the patient’s gastric mucosa will have a certain degree of damage, after eating will produce stimulation of the gastric mucosa, resulting in colic after eating. If the patient’s postprandial gastric colic is severe and cannot be relieved, the possibility of peptic ulcer perforation can be considered, and then the patient can feel a sharp pain like a knife cut, and need to consult a doctor in time. 3. Food intolerance: If patients eat certain intolerable food during meals, it will lead to allergic reactions to food in the gastrointestinal tract, causing patients to experience abdominal pain and bloating, nausea, diarrhea and other symptoms after meals. If the patient has long-term or recurrent symptoms of gastric cramps after eating, it is recommended to consult a doctor in time to identify the cause of the disease and carry out targeted treatment to avoid delaying the condition.
