Hi. I am 25 years old and I have recently noticed a few veins on my face. They are purple, they are not so big but I wonder is it is conected to a heart problem?Any idea?

When in doubt, get a physical. They could just be a few broken capillaries, or depending on where they are they could be just dilated/swollen capillaries due to things like lack of sleep. though if you're worried don't take the risk: call a doc. There is no such thing as a stupid question when it comes to your body.

It cannot be predicted better do some clinical test for confirmation.Do control your food intake and go by doctors advice.
