Can your tubes come untied if you lose a lot of weight?

Losing a significant amount of weight does not cause previously tied fallopian tubes to untie. Tubal ligation is a surgical procedure that permanently blocks or seals the fallopian tubes to prevent pregnancy. While weight loss can impact overall reproductive health and hormone levels, it does not reverse the effects of tubal ligation. If you have concerns about fertility after weight loss, it's best to consult a healthcare professional for personalized advice.
