What causes sunken veins?

* Dehydration: When you are dehydrated, your body does not have enough fluids to fill your veins, causing them to appear sunken.

* Low blood pressure: Low blood pressure can also cause your veins to appear sunken. This can be caused by several factors, including heart problems, certain medications, and dehydration.

* Weight loss: When you lose weight, you lose fat, which can cushion your veins and make them appear less visible.

* Aging: As you age, your skin loses elasticity and becomes thinner, causing your veins to appear more prominent.

* Family history: If you have a family history of sunken veins, you are more likely to develop them yourself.

Certain medical conditions can also cause sunken veins, such as:

* Deep vein thrombosis (DVT): DVT is a condition in which a blood clot forms in a deep vein, usually in the leg. This can cause swelling, pain, and discolouration in the affected area and can also lead to sunken veins.

* Varicose veins: Varicose veins are swollen, twisted veins that often appear on the legs. They can be caused by several factors, including obesity, pregnancy, and ageing.

* Peripheral artery disease (PAD): PAD is a condition in which the arteries in the legs become narrowed or blocked, reducing blood flow to the lower extremities. This can cause pain, numbness, and weakness in the affected legs and can also lead to sunken veins.
