Elevated hematocrit is a possibility, but these symptoms alone cannot establish the cause. February’s results also cannot tell you where your levels are now. Contact your TRT prescriber promptly about the recurring headaches and arrange a complete blood count, including hemoglobin and hematocrit, alongside a review of your testosterone levels.

The advice to “drink more water and donate blood” needs qualification. Staying adequately hydrated is sensible, but blood donation should not be the automatic treatment for an unexplained headache. Someone feeling better after donating does not prove that elevated hematocrit caused their symptoms.
If hematocrit is significantly elevated, your clinician should address the cause and review your TRT treatment. The Endocrine Society guideline recommends intervention when hematocrit exceeds 54%, including temporarily withholding testosterone under medical supervision, assessing for low oxygen levels or sleep apnea, and restarting at a reduced dose when appropriate. Therapeutic phlebotomy may also be considered. academic.oup.com
