Variacose veins have nothing to do with your diet. Typical causes of them are below.
Occupations that involve a lot of standing, such as nurses, hair stylists, teachers, and factory workers
Hormonal influences of pregnancy, puberty, and menopause
The use of birth control pills
Postmenopausal hormonal replacement
A history of blood clots
Conditions that cause increased pressure in the abdomen, such as tumors, constipation, and externally worn garments like girdles.
Other reported causes include trauma or injury to the skin, previous vein surgery, and exposure to ultraviolet rays.
I have some pretty bad variacose veins that run the length of my legs, they started to show up in my 30's. I'm now 41. If they're small purple spider veins then you can have them removed. Once they get to the big blue variacose vein stage and if they're causing pain or swelling then they should be stripped or removed.
