Why do my veins stick out of my arms?
2 doctors weighed in across 2 answers
Normal: The larger veins "sit" on top of the muscles, and absent substantial fatty tissue, are visible as you describe. Their size fluctuates with hydration. Their presence is normal and visiblity makes IV & lab draw much easier.

Multiple reasons: Veins return blood back to the heart and can carry a large volume of blood. Depending on many factors including levels of hydration, genetics, outside temperature and even physical activity, the size of the veins will vary. Another important function of the veins is to help control body temperature and this too will affect vein size. Also with aging, veins enlarge as tissue volume decreases.
