Has anyone had problems with weighloss after a hysterectomy?

I had my 3rd child, and started having probelms with poly cystic ovarian syndrome, then had endometriosis, and gained weight. I never lost the weight until I stayed completely away from carbs. and then after a year, I finally gave up on staying away from carbs. and gained weight back and probably then some. I had a full hysterectomy and after my hysterectomy I lost weight again then gained it back and more. Usually my weight has stayed the same never more or less, but since I've had the hysterectomy, I've gained a lot. Some women from work told me after about 4 years of having a hysterectomy I will start loosing the weight because my body is adjusting to a hysterectomy. They all 4 said they had a full hysterectomy and after 4 years they started loosing a tremendous amount of weight without dieting and being on hormones. Does anyone know if this is true or not? Has anyone had a full hysterectomy before? Please give me any experiences with weight problems? Also, how do I get the motivation to loose weight again? I want to stay away from carbs. again because that seemed like the only thing I could do in order to loose weight. I tried cutting back calories and watching what I eat, but it never worked. When I completely stayed away from carbs. and drunk lots of water is when I noticed a huge difference with weight loss.
