Case
� A big and corpulent postpartum woman came to the traditional medical outpatient service to ask for the acupuncture treatment. She said, “Overweight result in my postpartum depression. I really worry about my figure inflicting my happiness. I tried a lot of ways to lose weight, but they have never improved on it. Doctor, I want to know what would be the result to take this therapy. Does it have influence of sequelae? By the way, I persist in the safest way to be a slender lady.”

Am I suitable for acupuncture to
lose weight
There is no sufficient evidence to prove that acupuncture is efficacy
for weight loss. However, acupuncture has minor adverse effect for body.
