What does the body's blue veins warn about health?

Prominent veins on the hands and feet indicate health problems.

Veins are a clever system of one-way valves that perform the vital function of transporting dark, oxygen-poor blood back to the heart, where it is then re-oxygenated and continues its journey to nourish the body.

Veins are the blue blood vessels that appear on the skin. However, some people have skin with clearly visible blue veins, while others do not.

- By nature:In people with pale skin, the veins are also more prominent and easily recognizable. In addition, thin skin also makes the veins appear more easily, especially in older people. In some cases, the veins are born too close to the skin surface, making the limbs easily visible.

- Too much exercise:When you exercise at a high intensity, the veins in your arms and legs will appear, or this is most obvious in cyclists. According to medical expert Bradley Launikonis from the Faculty of Medicine at the University of Queensland (Australia), the reason is because a large amount of blood flows to the legs during exercise and stays there.

The blood vessels are thus enlarged, causing the veins to appear prominently. However, this is only a temporary phenomenon; when resting, the muscles will relax, and the blood vessels will gradually fade away.

- Pregnant women: To nourish the fetus, blood flow in the body of pregnant women is always higher than normal people, and because of that, the veins are inflated and appear on the skin.

- Have low body fat:Similar to people with thin skin, low body fat levels can also cause veins to appear. Low body fat also means that the subcutaneous fat layer is thin, and cannot completely cover up the veins hidden underneath.

- Varicose veins or phlebitis:If your skin suddenly becomes veiny, along with symptoms such as chest tightness, difficulty breathing, ulcers, or painful swelling... you should consider seeing a doctor. This could be a sign of more serious conditions, such as varicose veins or phlebitis.
