Question: I am a 35 yo, white, F, 5'0", 141 lbs, in good general health, + HX of stress related anxiety, only medication is Seasonique. I completed a 6wk course of HCG (bioidentical hormone infused with Vit B12) self injection diet under physician supervision and lost 23lbs. The diet was not as extreme as I have read online. The last injection was mid Sept. Later in Oct. I had a sudden onset of hypertension and tachycardia which continues intermittently still. Other symptoms: palpitations which wake me while sleeping, slight headache off and on, difficulty getting to sleep before 2 am I am just not tired or sleepy, I am either hot or cold, sweating more than usual but not profusely, irritability/quick to anger, face can be radiating heat while my hands may be freezing, increased urge to eat at night while no true hunger during the day. No chest pain or discomfort, no goiter, no weight loss/gain, no hand tremor. My PCP ran a CBC, CMP, TSH and T4 which were all WNL. The TSH was more toward the lower end of normal. T3 was elevated 3 points above the high range and T3 uptake was low just by 1 point below the low range. Resting EKG was normal. + Fam HX of both cardiac and thyroid (hypo not hyper) problems. My PCP wants to refer me to a cardiologist, however, I don't feel that this is cardiac related primarily. I feel there is an underlying condition triggering the sudden hypertension and tachycardia. I realize that stress related anxiety can play havoc on the body but I have suffered way worse stress than currently in my life and never had any of the symptoms I described above. #1 Where should I go from here? #2 Is there any real evidence suggesting that the HCG diet can cause hyperthyroidism? #3 Could I just be experiencing the early start of hyperthyroidism?
