This varies from person to person and one cannot be guided by the experience of other patients. Much depends on the severity of the disease, how long the patient has suffered from it, as well as the lifestyle and other factors contributing to it. Typically, treatments are given once per week for the first six to eight weeks. As the patient improves, visits are reduced to once every ten days, two weeks, once a month, and so on. As classical acupuncture is a preventative system of medicine, as well as curative, it is advisable for healthy patients to come in periodically for checkups and maintenance, as the pulses can reveal if anything is going wrong in the body long before it manifests itself as a visible symptom. Most of us don't wait for our cars to break down before taking them in to be checked. We should not pay less attention to our bodies!
