I am 19 years old. My height is 168 cm. Can I still get taller? I have varicose veins in my legs too. Does it give negative effects? Thank you

A little bit. Varicose veins can have a negative effect on your circulation health, especially if you are developing them at such a young age. Varicose veins increase your risk for blood clots and sores on your legs[ ulcers] that can impact your health. also the vein hurt and cause fatigue. The condition can often be cured. I recommend you see a vein specialist for evaluation with a leg vein ultrasound.
Varicose veins. Varicose veins can have a negative effect on your circulation health, especially if you are developing them at such a young age. I wound recommend that your set up an appointment with a vascular surgeon to examine your legs veins and discuss possible treatment options. The condition can often be cured & they tend to worsen if you leave them untreated. Leg vein ultrasound indicated.
Height. at your age, it extremely unlikely that you will get any taller than this. Your growth plates have closed. For varicose vein, it mostly has cosmetic effect rather any medical problems with them .
