Does Constipation Cause Weight Gain?

Constipation itself does not directly lead to weight gain, but long-term constipation may contribute to it. People who suffer from constipation often have slower metabolisms. When bowel movements are infrequent—either difficult to pass daily or occurring only every few days—the body may retain waste instead of expelling it efficiently. This build-up can potentially lead to weight gain, especially around the abdominal area. Chronic constipation can also cause additional issues such as bad breath, irritability, and sleep disturbances.

If weight gain is linked to constipation, addressing the underlying digestive issue should be the first step. Traditional approaches focus on improving the function of the spleen and stomach. For those with a "damp-heat" constitution, herbal remedies like Scutellaria (Huang Qin) and Capillary Wormwood (Yin Chen) can help clear heat and reduce dampness. Adding spleen-strengthening herbs such as Poria (Fu Ling) and Atractylodes (Bai Zhu) may further support digestion and waste elimination.

In cases of deficiency-type constipation, where the intestines lack sufficient moisture to pass stool effectively, nourishing the body's fluids becomes essential. Herbs like Lily Bulb (Bai He), Adenophora (Sha Shen), and Ophiopogon (Mai Dong) can help hydrate the digestive tract and promote smoother bowel movements. In addition to herbal therapy, gentle physical techniques like abdominal massage can be effective. Massaging the abdomen in a clockwise direction about 100 times before bed and upon waking can stimulate digestion and aid regularity.

For individuals who have experienced prolonged constipation accompanied by noticeable weight gain, consulting a qualified healthcare provider at a specialized clinic is recommended. A professional evaluation can determine whether there are deeper health concerns contributing to both symptoms. Addressing these root causes through personalized treatment plans can improve overall well-being and help manage weight more effectively.
