As people age, the walls of veins may become less elastic and more rigid due to changes in the structural proteins within the vein walls. This can cause the veins to narrow or become smaller in diameter. Additionally, the accumulation of fatty deposits or plaques within the veins can contribute to their narrowing.
The superficial veins of the upper extremities are best for cannulation.
