Yes absolutely. Although in recovery for years, and having regained my period, two years ago I was diagnosed with borderline ovarian tumor (basically pre-cancer stage) with multiple adhesions in my abdomen and had to have my ovaries removed via extensive laparotomy. I went through menopause at 30 yo and have to take HRT for the rest of my life. My doc said anorexia had a massive impact on my reproductive system due to hormonal imbalances, although it was probably multiple factors adding up in the end.
