What causes Enlarged Blood Vessels?
Enlarged blood vessels can occur from many contributing factors. Most commonly it is from heredity however, standing or sitting for long periods of time, obesity, hormonal replacement therapy, sun damage and even auto immune diseases can contribute. There are many types of enlarged blood vessels. Some such as vasculitis and large varicose veins should be treated by a vein specialist. However, others such as spider veins or telangiectasia are small dilated blood vessels that can usually be treated outpatient by a dermatologist.
Treatment options by a dermatologist will usually include laser (VBeam Perfecta) or intensed pulse light (IPL). This treatment involves the light being absorbed by the hemoglobin in the blood vessels which cause a heated reaction. In turn the blood will coagulate and cause the walls of the capillary to collapse. This can take several treatments over time to help fade the appearance.
Treatment for these are cosmetic and the patient should be followed closely by a dermatologist.
