*Welcome to the OutUK series looking at gay men and their health brought to you in association with the NHS* website.**
	Each week we'll tackle a different topic in our A to Z of Gay Health. We'll have features and advice on everything from relationships, sexual health, mental and physical conditions and how to stay fit. You can follow any of links provided below for more information direct from the NHS website, or see this week's feature O: Orthodontics.

Complications

Varicose veins can cause complications because they stop your blood flowing properly.

Most people who have varicose veins will not develop complications. If they do, it's usually several years after varicose veins first appear.

Bleeding

Varicose veins near the surface of your skin can sometimes bleed if you cut or bump your leg. The bleeding may be difficult to stop.

You should lie down, raise your leg and apply direct pressure to the wound. Seek immediate medical advice if this does not stop the bleeding.

If blood clots form in veins located just under the surface of your skin (superficial veins), it could lead to conditions such as:

thrombophlebitis - swelling (inflammation) of the veins in your leg
deep vein thrombosis - which can cause pain and swelling in the leg, and may lead to serious complications like pulmonary embolism
