Final answer:
Hysteroscopy with endometrial ablation is undertaken for conditions such as dysfunctional uterine bleeding and uterine fibroids, which cause heavy or irregular menstrual bleeding and pain.
Step-by-step explanation:
Hysteroscopy with endometrial ablation is undertaken for various reasons. One of the reasons is dysfunctional uterine bleeding, which involves abnormal bleeding from the uterus. Another reason is uterine fibroids, which are non-cancerous growths in the uterus. Both of these conditions can cause heavy or irregular menstrual bleeding, pain, and other symptoms, which can be treated through hysteroscopy with endometrial ablation.
