    Certain medical conditions such as varicose veins and cancers

    Sitting or lying for long periods of time e.g. being immobile after surgery or serious injury, going on a long journey (> 4 hours) by plane, car or train

    Using oral contraceptive pill or hormone replacement therapy containing oestrogen

    Being pregnant or if you delivered a baby in the previous 6 weeks
