Ema, yeah that's my understanding too is that the progesterone is helping to increase aldosterone and blood volume. What would you consider "large amounts"? I started with 50 mg progresterone, then went up to 100mg. Started with cream, but doc switched me to pills (bio identical progesterone). I do
have severe orthostatic problems wtih difficulty being upright at all. My aldosterone strangely shows normal, although my cortisol is quite low. Traditional treatments like adrenal supplmention, hydrocortisone, midodrine, fluorinef either didnt work or had opposite effect (made it even harder to be upright). My blood pressure on recent tilt table test went to 100/36 within 3 minutes, test was called off at 79/51 before he was worried i would faint, although I never have fainted. For me OI feels like overwhelming gravity that forces me to get horizontal or reclined. If this progesterone can help my quality of life I want to give it a try, but I appreciate your caution! Insomnia is my worst symptom to begin with before the progesterone I started. At first it made me sleep much better, then a week later it had the opposite effect. Hard to know what's going on.
