The most important signs of infection after colposcopy include a foul or fishy smelling vaginal discharge, worsening rather than settling pelvic pain, a temperature above 38C, feeling generally unwell or shivery, and heavy bleeding that soaks a pad within an hour. Infection after a colposcopy is uncommon, and most women recover with nothing more than a few days of light spotting and mild cramping, but recognising the warning signs early means treatment can be started promptly. This guide, informed by the clinical experience of Mr Saurabh Phadnis, explains what is normal, what is not, and when to pick up the phone.
Mr Saurabh Phadnis (MBBS, MRCOG) is a Consultant Gynaecologist and Gynaecological Oncology Surgeon in London, with more than 15 years of experience as a colposcopist and BSCCP accredited trainer status. He holds an NHS consultant post at The Royal London Hospital (Barts Health NHS Trust) alongside private practice across London, caring for women with abnormal smear results, cervical changes and gynaecological cancers. His approach is holistic and individualised, with clear explanations at every stage of diagnosis, treatment and follow up.
A colposcopy is a detailed examination of the cervix, usually arranged after an abnormal cervical screening result. A small biopsy or a treatment such as LLETZ (large loop excision of the transformation zone) may be carried out at the same visit, which leaves a small raw area on the cervix while it heals. Because the vagina is not a sterile environment, that healing surface can occasionally become infected.
The signs of infection after colposcopy tend to develop between three and ten days after the procedure, often just as you expect to be feeling better. Watch for:
One symptom on its own does not confirm infection. However, a combination such as smelly discharge plus increasing pain, or fever plus heavier bleeding, should always prompt a call to the colposcopy clinic, your consultant’s secretary, your GP or NHS 111.
Understanding normal healing makes the abnormal easier to spot. According to NHS guidance on colposcopy, most women can return to their usual activities the same day or the day after, particularly if only an examination was performed.
A watery discharge alone, even if it is fairly heavy, is a normal part of cervical healing. It is the smell, the fever and the direction of travel of your pain that distinguish genuine signs of infection after colposcopy from ordinary recovery. Further background on cervical assessment is available on the colposcopy service page.
Infection is a recognised but infrequent complication, and it is not a sign that anything was done incorrectly. The cervix heals from the outside in, and during that time bacteria that normally live harmlessly in the vagina can overgrow.
The Royal College of Obstetricians and Gynaecologists and the British Society for Colposcopy and Cervical Pathology both emphasise that colposcopy is a safe outpatient procedure, with serious complications being rare. Sensible aftercare reduces the small risk further.
Most infections respond well to a short course of antibiotics, so the aim is simply to be seen without delay rather than to worry. Timing your response to the severity of symptoms is the practical approach.
Sepsis is a rare but serious complication of any infection. The National Institute for Health and Care Excellence recommends urgent assessment for anyone with a suspected infection who becomes acutely unwell. If in doubt, attend your nearest emergency department or call 999.
Assessment is usually quick and does not normally mean repeating the colposcopy itself.
Treatment depends on the cause and severity. A course of oral antibiotics is the usual approach for a localised cervical or vaginal infection, and symptoms often begin to settle within 48 hours. Pelvic inflammatory disease may require a combination of antibiotics and closer follow up, while a rare severe infection may need intravenous treatment in hospital. Simple analgesia, rest and adequate fluids support recovery. Your clinician will discuss which option is appropriate for you, and antibiotics are prescribed only where genuinely indicated, in line with antimicrobial stewardship principles.
Importantly, an infection treated promptly does not usually affect the accuracy of your biopsy result or your future fertility. Your smear or biopsy findings will still be discussed with you as planned, and any onward management of conditions such as CIN, HPV persistence or other gynaecological conditions continues as normal.
Prevention is straightforward, and following aftercare advice for two to four weeks is the single most effective step.
The earliest signs of infection after colposcopy are usually a change in the smell of your discharge and pain that starts to worsen instead of easing, typically three to ten days afterwards. A raised temperature, chills or heavier bleeding often follow. Contact your clinic promptly if these appear.
Not usually. A dark brown, gritty discharge commonly reflects the healing paste applied to the cervix to stop bleeding and can last several days. It becomes concerning only if it develops a strong offensive odour or is accompanied by fever or increasing pelvic pain.
A small punch biopsy usually heals within one to two weeks, while an excisional treatment such as LLETZ can take up to four to six weeks. Watery or blood tinged discharge during this period is normal, provided it is not offensive smelling.
Showering is preferable to bathing in the first week or two, and swimming pools, hot tubs and saunas are best avoided until bleeding and discharge have stopped. This reduces the chance of bacteria reaching the healing cervix and lowers the risk of infection.
A treated infection does not normally alter your biopsy results, which are examined in the laboratory independently. Fertility is not usually affected. If you have had a large or repeated excision, your clinician will discuss any implications for future pregnancy with you individually.
Contact the colposcopy clinic that performed your procedure, your GP or NHS 111 for same day advice. Private assessment is also available in London, including at clinics where Mr Saurabh Phadnis consults, for women who want a prompt specialist review.
Colposcopy is a safe, well established outpatient examination, and infection is uncommon. Knowing the difference between normal healing and the true signs of infection after colposcopy, chiefly offensive discharge, worsening pain, fever and heavier bleeding, allows you to act early and recover quickly. Never feel that you are making a fuss by asking; colposcopy teams expect and welcome these calls.
If you are concerned about symptoms after a colposcopy, need clarification of an abnormal smear result, or would like a specialist opinion on your cervical health, you can explore the full range of gynaecology treatments in London or book a consultation with Mr Saurabh Phadnis, Consultant Gynaecologist and Gynaecological Oncology Surgeon, for an individualised assessment and clear, calm guidance on your next steps.
