NO RELATION BETWEEN WEIGHT INCREASE AND CONSTIPATION SHOWN AFTER SMOKING CESSATION, AND SMALL INTESTINE MOVEMENT.

It is known that smokers experience temporary body weight (BW) increase or constipation after they stop smoking. Despite various studies on its mechanism being done, it still remains unknown. We conducted a before-after smoking cessation test with those smokers who agreed to stop smoking and examined how their body measurements including weight and small-intestinal transit time measured by breath hydrogen test change after receiving the treatment of smoking cessation. This study also involves the difference between smokers and non-smokers, which is shown by body measurements including weight and breath hydrogen test conducted for those non-smokers agreed. This shows that there is an obvious increase in body weight after the cessation of smoking (before BW 71.7±15.3Kg, after BW 72.7±15.6Kg, p=0.003), while no obvious change was seen in the movement of small intestine(before . t1/2ex1)：12.72±18.17, after t1/2ex:23.1±59.8, p>0.05). This indicates that the presence and the absence of smoking have little influence on the movement of small intestine. As a result of this study, it was confirmed that there is no relation between weight increase and constipation shown after smoking cessation, and small intestine movement. 1) Ghoos YF, Maes BD, Geypens BJ, et al.
