Ive been noticing the veins in my arms becoming more prominent. Darker blue, longer, more branching. Im 28 and i just started working out on a beginners, easy level. I have tetrology of fallot(repaired) and as a heart patient when I notice these sorts of things I become concerned. Any idea what it may be caused by? Should I be worried?
Hi this may be due to variation in blood supply. Darker and more branching are due to increase in blood supply to the tissues. This type of prominence in vessels are normal in the initiation of working as the vessels dilate for increase blood supply. No need to worry for now. But if you develop any signs of cyanosis, ischemia then consult your doctor for further management. Hope this helps you. Regards
