Cervical Cauterisation
Also known as: cervical diathermy, cervical coagulation, or cervical ablation
Cervical cauterisation is a medical procedure to remove abnormal tissue from the cervix. It involves applying heat, cold or chemicals to remove or destroy the affected tissue.
What is cervical cauterisation?
Cervical cauterisation involves applying heat, cold or chemicals to remove the affected tissue. It is most commonly performed to destroy abnormal or precancerous cervical cells, helping to prevent cervical cancer. It can also be used to treat benign conditions such as cervical ectropion when they cause troublesome symptoms.
What is cervical ectropion?
Cervical ectropion, also known as cervical erosion, occurs when the glandular cells from the inside of the cervical canal are exposed on the outside of the cervix. This condition can be caused by hormonal changes, especially related to oestrogen. Common symptoms of cervical ectropion include unusual vaginal discharge or bleeding. It’s a generally benign condition and often resolves on its own; however, treatments are available for cervical ectropion if it’s causing symptoms.
Cervix anatomy
The cervix is the lower part of the uterus that opens into the vagina. It’s made up of two types of cells: the delicate, thin cells lining the cervical canal and the thicker cells on the outside. Cervical ectropion occurs when the inner glandular cells are exposed, making the cervix appear red and inflamed.
Causes and risk factors
Several factors can increase the risk of cervical ectropion:
- Hormonal changes – fluctuations in hormone levels during pregnancy or menstruation can cause the condition.
- Oral combined contraceptive pill – using this contraceptive method means higher oestrogen levels, which can cause cervical ectropion.
- Young age – younger women are more susceptible, as they have higher hormone levels.
- Previous cervical surgery or biopsy – procedures on the cervix can increase the risk of ectropion.
- Infection or inflammation – conditions that cause inflammation of the cervix can also be a contributing factor.

Ways to payBefore the procedure
Initial consultation
The initial consultation is the first step before cervical cauterisation. During this appointment, a consultant gynaecologist will go through your symptoms, medical history and any previous investigations you’ve had, such as biopsies, smear or swabs. This thorough assessment will help determine if cervical cauterisation is the proper treatment for you. Your gynaecologist will also explain the procedure in detail, including the different types of cauterisation available, such as diathermy, cryocautery or chemical cautery and explain the benefits and risks. They will address any concerns you may have about pain, recovery time or impact on future pregnancy outcomes.
Preparation for surgery
Your consultant will provide you with specific instructions on how to prepare for the surgery, which may include fasting for a particular period before the procedure and arranging for someone to drive you home afterwards.
During the procedure
Types of cauterisation
Subsequent steps depend on the type of procedure performed. There are several types of cauterisation, each with its method and benefits. The most commonly performed are:
Diathermy
Diathermy is a medical procedure that uses high-frequency electric currents to generate heat within body tissues. This heat can be used to cut, coagulate or destroy abnormal tissues. Diathermy is performed in a gynaecologist’s office and can be done with minimal discomfort to the patient.
Cryocautery
Cryocautery, also known as cryotherapy, is a procedure that uses extreme cold to destroy abnormal tissues. An instrument called a cryoprobe is used to apply the cold temperature directly to the affected area. The procedure is quick and can be done in an outpatient setting.
After the procedure
Immediate aftercare
After cervical treatments such as diathermy or cryocautery, you will need to follow specific aftercare instructions to ensure proper healing and recovery. You might experience some period-like pains or discomfort after the procedure. You can use standard pain relief options such as paracetamol or ibuprofen to manage these symptoms.
It is also common to experience increased vaginal discharge post-treatment. Monitoring for any abnormal changes in the discharge is crucial, as it could indicate an infection.
Follow-up appointments are essential to ensure you are recovering properly and to assess the outcome of the treatment.
Long-term recovery
Long-term recovery after cervical ectropion treatment involves abstinence from sexual intercourse and using sanitary pads instead of tampons for a period specified by your gynaecologist. This helps prevent complications such as improper healing, moisture-related issues and risk of infection.
Appointment and Treatment Plan
Initial Consultation
Your gynaecologist reviews your symptoms, history, and test results. They’ll explain the types of cauterisation (diathermy, cryocautery, or chemical), and answer questions about pain, recovery, or fertility impact.
Pre-procedure Preparation
You may be asked to fast before the procedure and arrange transport home. Follow all instructions from your consultant carefully.
Procedure
Depending on your case, your gynaecologist may use:
-
Diathermy – Heat from electric current to treat tissue.
-
Cryocautery – Extreme cold applied via a cryoprobe to remove abnormal cells.
Both are quick and usually done in the clinic with minimal discomfort.
Immediate Aftercare
Mild cramping and increased discharge are normal. Use pain relief like paracetamol or ibuprofen if needed. Watch for signs of infection and attend your follow-up.
Long-term Recovery
Avoid sex and tampons until your doctor says it’s safe. Stick to pads and keep the area clean to support healing and prevent complications.

FAQs
Cervical cauterisation is done to treat various conditions affecting the cervix, such as cervical ectropion, chronic cervicitis or precancerous cervical cells. The procedure removes abnormal tissue, reduces symptoms like bleeding or discharge and prevents progression of cervical abnormalities. It’s an effective treatment for women who are experiencing discomfort or complications from these cervical conditions and want to improve their reproductive health.
Healing after cervical cauterisation takes a few weeks. During this time, you may experience some vaginal discharge, spotting or period-like pain, which are normal as the cervix heals. You should follow post-procedure care instructions, including avoiding sexual intercourse and using sanitary pads instead of tampons, to ensure proper healing. Follow-up appointments with a consultant gynaecologist are essential to monitor recovery and address any concerns.
