I went into hospital expecting to have a hysterectomy performed and my ovaries removed, when I was 69 - three years ago.
As it transpired, only my ovaries needed to be removed, as what had looked like a massive fibroid inside my uterus was actually a benign growth on the one ovary which had pushed it downwards in front of my uterus.
I am mentioning this to say that even the best ultrasound scans are apparently not totally reliable, and Ihope you will be as fortunate.
I assume your consultant knows you are a diabetic and that he/she is not unduly concerned that this will slow down the rate you heal at, or cause other complications, so please do not worry about this.
I bleed too heavily, due to a certain disability to absorb Vitamin K which is responsible for helping our blood to clot, which concerned me, but the surgeon knew of this and assured me I would be given any and all treatment necessary during and after the op.
Even although I had not had a full hysterectomy done, I tireded easily for some time afterwards - about six weeks. It was easily for me to tell when I had done a little too much, as I felt queasy and sick.
Do please rest and obey instructions not to lift or carry anything heavy - my surgeon told me not even to carry a full litre carton of milk, or to pour my own coffee it was made in a family sized pot. This may seem over-cautious, but I am glad I followed his advice, and the advice to rest frequently during the day, and to roll over onto my side, and swing my lower legs over the side of the bed, before attempting to get out of bed, or off a sofa. This last trick took some getting used to, but the precautions have paid off.
Six months after the op. I noticed to my surprise that I was physically stronger than I had been for three or four years.
Another perk is that I no longer have to wee so frequently as I was doing prior to the op.
I hope and trust you will be as happy with the results of your op as I am with mine.
