Bulging veins on the back of the hands generally refer to bulging and dilated veins, which generally do not require treatment, but for more severe cases, surgery may be an option to improve venous pressure. For many slim women, bulging and dilated veins can occur on the back of the hands. One reason for this is that the subcutaneous fat on the back of the hands is thinner, and the dilation of the blood vessels becomes more obvious; another reason is that the blood vessels appear dilated due to the reduced elasticity of the individual’s blood vessels. If the bulging veins in the upper limbs and hands are caused by thrombosis in the upper limbs, for example, then timely consultation and treatment in the hospital is required. Women whose veins are not obviously dilated can improve through diet and exercise, and do not need special treatment. Eat collagen-rich foods such as pig’s trotters, Colla Corii Asini, sea cucumber, etc. In severe cases, surgery can be performed to improve venous pressure. Patients are advised to exercise properly in their daily life to enhance their physical fitness and elevate their hands to increase the volume of returned blood.
