In Traditional Chinese Medicine, the belief is that excessive weight gains are caused mainly by an imbalance in the body. This imbalance can be due to malfunctions of the spleen and liver organ systems. These areas involve the endocrine system and kidneys, and TCM may help treat water retention and stimulate nerve and hormonal rebalance. The spleen and thyroid gland are also targeted and may help with sugar and hormonal rebalancing. Finally, the adrenal and ovary glands are addressed to help treat weight gain due to menopause or premenstrual syndrome (PMS). Some people may notice the effects of acupuncture fairly quickly.
