Dear patient, the clinical uses of HCG(human chorionic gonadotropin) in allopathic medicine includes following 1. Its detection in urine of a women complaining of missed periods for more than two weeks signifies a positive pregnancy test 2. it is used as a tumour marker for certain types of cancers like seminoma, choriocarcinoma, germ cell tumours, hydatidform mole, teratoma with elements of choriocarcinoma, ise let cell tumours and testicular cancers 3. To treate female infertility due to anovulation by inducing ovulation and male infertility due to hypogonadism Side effects of HCG injections include 1. Allergic reaction causing heaves, breathing difficulty, swelling of lips, face ,tongue and throat which is called angioneurotic edema 2. Overian hyperstimulation syndrome characterised by severe pelvic pain, stomach pain, shortness of breath ,nausea,vomiting and diarrhoea, decreased urine output ,severe head ache and dizziness,confussion,pain,redness, warmthness, tingling and numbness of hands and feet. Both these side effecte i.e angioneurotic edema and overian hyperstimulation syndrome are life threatning conditions. Besides these two other less severe side effects of HCG include pain,swelling and redness at injection site, depression and irritability and breast tenderness and swelling Use of HCG for weight reduction in obesity was proposed by British endocrinologist Albert T W Simeons as an adjunct to ultra low calorie weight loss diet ( less than 500 calories) but his results were not reproduced by other researchers and FDA (FOOD AND DRUD ADMINSTRATION) has clearly disapproved its use for this purpose.FDA has mantained that there is no substantial evidence that HCG increases weight loss beyound that resulting from caloric restruction, that it causes more attractive and normal distribution of fat or that it decreases the hunger and discomfort associated with calorie restricted diet. FDA clearly considers HCG diet products as fraudulent and neither effective nor safe for weight reduction. Now considering the symptomatology of the side effects that you perceived it seems that probably you were experiencing overian hyperstimulation syndrome which is considered as a life threatning condition and you were lucky to fare it well and also considering the role of HCG for weight reduction it seems me appropriate that you better stop it compleatly and don t use it again as it is said that life is so beautiful, it is better to enjoy it as an obese or over weight person than to die of some unknown poison
