Is fat present in veins? If yes why fat deposits not found in veins.?

Fat deposit in the capillaries cause serious problem. But in veins does the problem arise.
Fat does not deposit in capillaries. I deposits in arteries because the high pressure maintained over time damages the intima and fatty deposits develop. Veins are low pressure and may have blood clots but not atheromatous plaques.
I dont really know, ubt I do knwo that the pressure in arteries is much higher than viens. It probbaly has somthign to do with the fluid mechanics of blood flow . IF the flwo i nthe viens is slow enough, the blood itself might flow in a condition where it acts like a plug. This would make it harder for fat to deposit.
The plaque that causes arterialsclerosis is largely composed of fat, and this is what causes strokes and contributes to heart attacks.
this can be a leader of heart attacks and can even cause a stroke.
can be very painful as well.
and even can cause death.
Correction, the plaque that builds up is calcium deposits,which is arteriosclerosis ( hardening of the arteries). The fatty deposits which build up in the intima of arteries and thereby making the lumen smaller is called atheriosclerosis( too many cheeseburgers and doughnuts).
