If you have taken Chinese medicine for spleen deficiency and have stomach distension, you should consider that it is caused by taking too much medicine, taking medicine too quickly, or the medicine is nourishing and greasy. 1. Taking too much medicine: If you take too much Chinese medicine for spleen deficiency, it is easy to burden and stimulate the intestines and stomach, so that the intestinal and gastric transport function decreases, and it is easy to have a bloated stomach. 2. Drinking medicine too quickly: If you drink Chinese medicine for spleen deficiency too quickly, it is easy to bring a lot of air into the stomach, thus resulting in stomach distension. 3. The nature of the medicine is nourishing and greasy: if the Chinese medicine for spleen deficiency is too nourishing and greasy, it will cause the burden of absorption and digestion, thus affecting the transportation and digestion of the spleen and stomach, and the stagnation of qi in the stomach (obstruction of qi’s operation), which will lead to gastric distension. If gastric distension occurs after taking Chinese medicine, it is recommended to stop taking the medicine and consult a doctor.
