Medical weight reduction is dependable and safe. Everybody is familiar with the use of acupuncture for weight loss and cosmetic purposes. Acupoint fiber insertion is a refinement and extension of acupuncture. The advantages of acupoint fiber insertion are that the treatments are convenient, and stimulation of the point is continuous. Most acupuncture treatments last about 20 minutes. However the subcutaneous insertion of fibers from sheep intestine provides continuous point stimulation until the fiber is absorbed by the body in about 2 weeks. Two days after insertion a daily pressing of the point will increase its effects. The disadvantages are an added danger of infection if not taken care of properly or if it is not compatible with the person's constitution. Proper attention is needed to prevent infection and inflammation. Similar to acupuncture acupoint fiber insertion has a two way regulatory effect on the body. If the body is in an excited state the subcutaneous fiber induces an inhibitory effect and vice versa. The strength of stimulation depends on the thickness of the fiber and the method of insertion. Those who have difficulty losing weight and those who regain weight easily can use traditional needling along with subcutaneous fibers to strengthen the effects.
