First seen May 01, 2026 · Last updated May 14, 2026 · Updated 5 times

Summary

This study compares two blood-thinning injections, tinzaparin and enoxaparin, to see which better prevents dangerous blood clots after weight loss surgery. About 180 adults having laparoscopic sleeve gastrectomy or gastric bypass will be randomly assigned to one of the two drugs. A single extra blood test on the second day after surgery will measure whether the drug is working properly, and patients will be followed for 30 days to check for clots or bleeding.
