Genetic Factors
Family history plays a significant role. If your parents have thread veins, you're more likely to develop them.

Lifestyle Factors
Prolonged standing or sitting, lack of exercise, obesity, and sun exposure can contribute to their development.
Medical Conditions
Certain conditions like rosacea, liver disease, or connective tissue disorders may increase risk.
External Factors
