ABSTRACT
<p><b>OBJECTIVE</b>To observe the clinical effificacy of treatment with catgut implantation at acupoints on simple obesity.</p><p><b>METHODS</b>Following the theory of Chinese medicine (CM), pattern identification (PI) and treatment was based on the patient's symptoms and signs. Patients were observed during three courses and one year following treatment through self-comparison before and after six or seven acupoints catgut implantation. Obesity was divided into fifive types based on PI: (1) Stomach (Wei) and Intestine excess-heat, (2) Spleen (Pi) defificiency and phlegmwet stagnancy, (3) Liver (Gan)-qi stagnation, (4) Spleen-Kidney (Shen) yang deficiency, and (5) Liver-Kidney yin defificiency. Changes in the following measurements were recorded in 820 patients: body weight, body girth, skinfold thickness, body mass index (BMI), fat percentage (F%) and waist/hip ratio (WHR) and in the following blood values: leptin (LP), insulin (INS), blood lipids, fasting blood sugar (FBS), and insulin sensitive index (ISI) before and after the treatment. Values were compared with those of healthy controls (normal group).</p><p><b>RESULTS</b>Catgut implantation showed effificacy with all fifive types of obesity. Effificacy was greater in males than in females. There was no signifificant difference between the different types by Kruskal-Wallis H test, but the effect was best and of the highest number in patients with Stomach and Intestine excess-heat. Skin-fold thickness, body weight, waist circumference, F%, BMI, and WHR in all 820 cases decreased after treatment (at 90 days and one year), with signifificant differences before and after treatment (P<0.01). Improved metabolism of blood lipids was also seen. Following treatment, LP, INS, and FBS decreased signifificantly (P<0.01) and ISI increased signifificantly (P<0.05).</p><p><b>CONCLUSION</b>Catgut implantation at acupoints provided effective and persistent results, convenience, safety, painlessness, and prolonged effect with no side effects, resulting in reduced body weight and fat and improvement in body shape.</p>
