Sweating profusely after eating may be caused by physiological factors, but also by pathological factors such as qi deficiency and gastric heat. 1. Physiological factors: In daily life, consuming too hot or too spicy food may lead to sweating while eating, which is normal and no need to worry. 2. Qi deficiency: the patient’s body has a deficiency of qi, which leads to a weakening of the solidification (consolidation) function, and when there is movement during meals, it will lead to the leakage of fluids, thus resulting in the appearance of a full head of sweat. 3. Stomach heat: If there is solid heat in the stomach, the heat will vaporize upwards, forcing the fluid to go out, which may lead to the performance of sweating profusely when eating. The patient should go to the hospital to clarify the specific cause of the disease, and then follow the instructions for treatment.
