Treatment frequency and the number of sessions required depend on several factors, including your constitution, mental state, the severity and duration of the health condition, lifestyle habits, and the quantity and quality of your Qi. Acupuncturists believe that health determinants are unique to each individual. Typically, some change is noticed within 5 or 6 treatments, although occasionally 1 or 2 treatments may suffice. Chronic conditions typically require more time to resolve than acute ones.
