Impact of Smoking, Alcohol Use and Exercise on Underweight after Gastrectomy: A Nationwide Cohort Study of Gastric Cancer Patients in Korea

This research investigates how smoking, alcohol use, and exercise influence the risk of underweight after gastrectomy in gastric cancer patients.
Analyzed data from a nationwide cohort of gastric cancer patients
Assessed the impact of smoking cessation, alcohol use, and exercise on weight status post-surgery
Utilized statistical analyses to determine associations between lifestyle factors and underweight outcomes.
Smoking cessation is linked to a reduced risk of postoperative underweight
Regular exercise shows a protective effect against underweight in these patients
Alcohol use does not significantly affect the risk of postoperative underweight.

Smoking cessation and regular exercise are associated with a reduced risk of postoperative underweight in GC patients following gastrectomy.
