I have written several blogs on the possible complications of using HCG for dieting. Of the problems HCG could cause I included excess facial and body hair, acne, oily skin, ovarian cysts and now I add unwanted pregnancy. It is important to remember that HCG has, for many years, been an important hormone in fertility treatments. During fertility treatments HCG is injected at a precise moment to cause release of the ripened egg, the process called ovulation. A similar effect of HCG treatment could cause women who normally dont ovulate to suddenly and unexpectedly release an egg. In essence, women on HCG injections for dieting are actually participating in their own fertility treatments. I came to this conclusion because this past week I became aware of an actual case of this occurring. A woman in her late 40s who was in early menopause without menstrual cycles for about 6 months, participated in two consecutive HCG diet programs each lasting 6 weeks.
