The aim of this study is to explore the correlation of laboratory data, hormone peptides, and quality of life with different traditional Chinese medicine (TCM) syndrome groups in type 2 diabetes patients. Of 513 registered patients, 179 subjects aged between 20 and 65 years and having type 2 diabetes mellitus (T2DM) for more than 1 year were enrolled in the study. All the participants were asked to fill out a questionnaire on diabetic TCM syndrome groups, which was designed by professional TCM doctors, and two questionnaires on the quality of life (QOL), WHOQOL-BREF Taiwan version and Medical Outcomes Study (MOS) Short Form-12 (SF-12). The biochemical characteristics and hormone peptide levels were collected at the same time. The patients in any one of the six TCM syndrome groups had the trend to have worse QOL. Especially, patients with qi deficiency had worse life quality on every aspect compared to those without qi deficiency and were fatter than others. We also found that the subjects who had qi deficiency, qi stagnation, and yin deficiency at the same time had worsened condition. We consider that patients with qi deficiency may also be at a higher risk of developing other complications. They need more advanced health care than others. This self-reported questionnaire will be a reference for health care workers screening those T2DM patients who have a higher possibility of developing other complications. Especially in remote areas, where there is a lack of medical resources, an easy-to-use tool such as the one in the present study for detecting and evaluating disease conditions is needed.
