Is the uterine ablation a risky thing to do?

Nope. In good hands, no. Endometrial ablations are done in the or or office, with different types of systems, and your doc will review how the procedure works and what you can expect during and after. Like any procedure, make sure you understand your options, make sure your doc is qualified, and most important - you have to be comfortable with all of it. Good luck.
Low risk. Uterine or endometrial ablation is a procedure where an instrument (several types available) is placed through the cervix and the uterine lining is burned off. After the period will be very light or none at all. The biggest risk is putting a hole in the uterus at the time of the procedure. This can injure the bowel or surrounding pelvic organs. This happens rarely. Choose an experienced doc.
