Cold Coagulation

Cold Coagulation


    The aim of the treatment is to destroy all the abnormal cells in your cervix without affecting too much normal skin.

    Cold coagulation is a quick heat-based treatment.

    A local anaesthetic is given to freeze the area. There may be slight discomfort but it should not be painful. The whole procedure takes only 5-10 minutes.

    Sometimes this treatment can be used to treat bleeding between periods and bleeding after sex. If you have had cold coagulation as a treatment for bleeding you should continue to have your cervical smears as normal.

    What Should I Expect After My Treatment?


    You may experience some bleeding. If excessive, for example soaking through sanitary towels, contact NHS 24 or your local A&E. Do not use tampons for the bleeding as it can make the bleeding last longer.



    You may experience abdominal cramps for a couple of days. Take simple pain-killers like ibuprofen or paracetamol if required.



    You may experience a watery, blood-stained discharge for 4-6 weeks until the treated area of the cervix has healed. A foul-smelling discharge is not normal. Please contact the Colposcopy Clinic or your GP for advice.


    Hygiene / Hot Bath

    Avoid taking a hot bath tonight. A shower or lukewarm bath should be fine.



    Avoid sexual intercourse until the bleeding and discharge have settled, due to the risk of infection and potential discomfort. After that your sex life should be completely unaffected.

    You may feel tired, upset or weepy for a couple of days after your treatment. This is quite normal and can be a natural reaction to the worry of having this minor operation.

    Follow Up

    Treatment of your cervix is very effective. We know that over 95% of women have no further problem after treatment for pre-cancerous cells of the cervix.


    It is important for you to attend your follow-up visit in 6 months time, and to have your smears done more frequently as advised by your doctor.


    Do not hesitate to phone if you experience any unexpected or severe side-effects.
