Yes, i know someone that is trans and has had a stroke.
There are a few things that you can check and do to reduce your risk.
Things to quit doing are smoking, eating crap food, eating too much salt, and drinking excessively.
Things to begin doing are monitoring your blood pressure, getting exercise, drinking more water, and eating small, light, healthy meals. Know the symptoms of a TIA and get to a medical facility ASAP if they happen.
HRT elevates the risks of blood clots. A healthy lifestyle helps reduce that risk.
I understand why people self-medicate but you put yourself at great risk of a stroke and other problems if you choose to do so.
Believe me, you don't want a stroke and they often hit with no warning at all.
