Cold hypersensitivity is excessive sensitivity of each body part, particularly limbs and low backs, but sometimes it affects upper abdomen region in G-I trouble patients. We conducted this research on 69 patients who came and took the both exam of gastroscopy and D.I.T.I. in Kangnam korean hospital Kyung Hee university. So, we researched the significance of temperature deviations on upper abdomen which was studied separately by gastritis group, digestive function group and H. pylori group. The result was : 1. The temperature deviation of Zhongwan(Ren12)-Danzhong(Ren17) of gastritis group was significant, it means that patients with severe gastritis have more significant cold hypersensitivity in upper abdomen than the patients who has not gastritis(p<0.005). 2. The temperature deviation of Zhongwan(Ren12)-Danzhong(Ren17) of indigestive patients in digestive function group was significant(p<0.05) 3. The temperature deviation of Zhongwan(Ren12)-Danzhong(Ren17) of H.pylori positive patients in H.pylori group was not significant. 4. The clinical relationship or tendency was not found both between H.pylori group and gastritis group and between H.pylori group and digestive function group.
