If you sweat when you eat, you need to consider the problem from both Chinese medicine and psychology. From the Chinese medicine point of view, this is a serious deficiency, and sweating after eating is caused by spleen and kidney deficiency. From a psychological point of view, there are usually several factors: first, the most common factor is hyperthyroidism, hyperadrenocorticism, etc., resulting in the rapid decomposition and metabolism of heat in the body after eating, resulting in the clinical symptoms of sweating after eating. Secondly, in the case of diabetes, there is a transient increase in blood sugar after eating when the blood sugar is not well controlled, resulting in a state of hyperdegradation and metabolism that leads to sweating immediately after eating. Third, infectious diseases, such as tuberculosis, rheumatism, and connective tissue disease, may also have clinical symptoms of sweating immediately after eating.
