This is also a good opportunity to discuss important travel health issues including safe food and water, accidents, sun exposure and insect bites. Many of the problems experienced by travellers cannot be prevented by vaccinations and other preventive measures need to be taken.
Age and genetics. As you get older, the veins in your hands may become more visible. Additionally, some peopleâs veins are naturally more visible. This could be due to skin pigmentation, body fat distribution, or a variety of other genetic factors. In most cases visible veins in hands are not a sign of a medical condition, or of any other problems.
For most people, it is a cosmetic issue, but for some people varicose veins may cause pain. In some cases serious complications, such as phlebitis (inflammation of the veins), skin ulcers, and blood clots, can happen. Veins move blood from your body to your heart. When the one-way valves in your veins get weak, they may allow blood to flow backward and pool in your veins. That causes your veins to get bigger. Varicose veins usually show up in the legs and feet, because standing and walking increases the pressure on these veins.
