The capillaries on the feet are very visible and are actually caused by poor venous return. The principle is the same as that of varicose veins and can be considered as an early manifestation of varicose veins or a precursor of varicose veins. This dilatation of capillaries is formed by the aggregation of capillaries less than 1mm in diameter, also known as reticular varicose veins or spider veins. The capillaries on the feet are apparent because the feet are distal to the limb and venous return needs to overcome gravity back to the heart. Therefore, the most distal end is the most likely to form a return obstruction, and the capillaries on the feet are the most likely to develop this dilated change. On the other hand, it is due to the weakness of the skin and subcutaneous tissues on the feet that once there is a slight venous return, there is a significant dilatation of the blood vessels on the feet, which is revealed and creates a significant capillary on the feet. This condition also needs to be treated according to the condition and according to the principles of varicose veins and if necessary, it also needs to be treated in a hospital.
