The belly takes the longest, I believe. At least that's my own experience and I'm only perimenopausal.
I had a fibroid removed that was big as a grapefruit. Since fibroids are really common for women, I've often wondered if a lot of the bellies of older women were also big giant fibroids. The surgeon said that my big fibroid was actually not the cause of my menstrual problems since it was formed within the walls of the uterus. I had another smaller one that was the cause of my problems. I probably never would have noticed the big one if it hadn't been for the little one and I might still be walking around with a fibroid now as big as a football.
