As lifestyle choices also play a huge part in the development of varicose veins, in mild cases it might be enough to change bad habits:
Moderate alcohol consumption, quitting smoking and losing the excess weight can work wonders. Being overweight is especially hard on our body and veins, as more weight means more burden.
You should avoid lifting heavy objects and standing still for a long period of time, because these activities put an increased strain on our legs. When your job requires to stand for a long time try to exercise your legs often.
It’s recommended not to wear heels, tight clothing or to have long hot baths.
However if your condition is severe, surgery is the option you want to choose. This eliminates the risks for complications like thrombosis, pulmonary embolism or leg ulcers. Nowadays there are different surgeries (stripping or laser) available from which your doctor chooses the one that suits you most.
You should use compression stocking in every case of varicose veins. This supports the walls of your veins.
Beside all this you can do a lot for the health of your veins with some exercise. You can do some of them even when at work: draw circles in the air with bending your ankles, imitate the movements of cycling, stand up on your tiptoes and stand back etc.
