What causes raised veins on hands?

Raised veins on the hands can have various causes, including:

1. Aging: As people age, the skin loses its elasticity and becomes thinner. This can make the veins more visible.

2. Genetics: Some people are more likely to have visible veins due to their genes.

3. Hormonal changes: Certain hormonal changes, such as those that occur during pregnancy or menopause, can cause the veins to become more prominent.

4. Weight loss: Rapid weight loss can cause the skin to become loose and saggy, which can make the veins more visible.

5. Sun exposure: Excessive sun exposure can damage the skin and make the veins more visible.

6. Certain medical conditions: Certain medical conditions, such as liver disease, heart failure, and kidney disease, can cause the veins to become raised.

7. Medications: Certain medications, such as steroids, can cause the veins to become more prominent.

8. Dehydration: Dehydration can cause the veins to become more visible.

9. Intravenous drug use: Intravenous drug use can damage the veins and cause them to become raised.

10. Physical exertion: Strenuous physical activity can cause the veins to become more visible.

If you have raised veins on your hands and are concerned about their appearance or potential health implications, it's important to consult with a healthcare provider for an evaluation. They can determine the underlying cause and recommend any necessary treatment options.
