Hi, I was wondering if anyone has lowered their hematocrit using a cpap machine? I am on trt, testosterone cypionate, and take 14mg daily Im. I was just diagnosed with severe sleep apnea and have been using a cpap. My hematocrit is consistently at 53.8 on blood tests and when I donate blood I feel awful afterwards. My blood pressure is always normal and I do not really have sides from my hematocrit being high. Thanks.
