Is Hysterectomy Advisable For Enlarged Uterus?

I am a healthy, 36 year old mother of 3. I had three 3c-sections, the last one requiring a vertical incision. I am scheduled to have a tummy tuck with umbilical hernia repair in three months. I was recently examined by my GYN and she recommended getting a hysterectomy due to complications from an enlarged uterus. Is this too much surgery to do at once?
