I was 40 when I had my hysterectomy. First, you need to take care of yourself. If they say don't do anything stressful for six weeks, listen to them. My husband was in the military when I had mine, and we were transferring within a month. Because I was working around the house and doing things I should not have done, I developed an infection. Luckily, they caught it, I started taking it easy and all was well. I lost weight after the surgery. I gained a lot of weight later, but I think it would have happened even without the surgery. Track and measure and you'll be fine.
