If you gain weight after taking Chinese medicine, you can generally lose weight by stopping the medicine for 2-3 months and exercising and controlling your diet. Chinese medicine itself will not lead to obesity, but taking Chinese medicine that strengthens the spleen and improves qi and blood can promote the peristalsis of the gastrointestinal tract and increase the absorption of nutrients. The increase in reserves after improving gastrointestinal function through herbs may cause obesity, and its a normal therapeutic effect, so there is no need to worry too much. In addition, due to the change of the patient’s physique, it may lead to an increase in appetite, and if excessive sugar and fatty foods are consumed at this time, it may also lead to weight gain. It is recommended that when patients become obese, they should stop taking the medication according to the treatment effect and the guidance of the TCM physician. Some patients can lose their original weight after stopping the medication for 2-3 months and at the same time exercising appropriately and eating reasonably. Therefore, patients should avoid overeating, eating too much greasy and sugary food, and exercising actively during the period of taking herbal medicines for strengthening the spleen and Qi and replenishing Qi and blood to avoid excessive weight gain.
