What should you know about hormonal coil types?

A hormonal coil is a small, flexible device placed through the cervix into the womb. It releases progestogen mainly in the womb, thickening cervical mucus and making the womb lining thinner. This can prevent pregnancy and may reduce menstrual bleeding. Product names, frame size, hormone dose and licensed length of use vary, so the exact device matters.

A coil may also be considered when heavy bleeding occurs with conditions such as uterine fibroids or adenomyosis, or when womb-lining protection is needed during some hormone treatments. It does not treat every cause of pelvic pain, including endometriosis, and it is not suitable for everyone.

A clinician will review pregnancy possibility, bleeding patterns, pelvic symptoms, infection risk, womb shape and relevant medical history before recommending a device. Ask which types are available locally, how long the chosen product is intended to remain in place and whether a smaller frame could make insertion more comfortable.

Cramping and spotting can occur after insertion, and bleeding patterns may change while the body adjusts. Learn how to check for the threads if your clinician advises it, and keep the follow-up plan. The device can be removed by a trained clinician when you want to stop or change methods.

Contact a clinician promptly for worsening pelvic pain, fever, unusual discharge, pain during sex, very heavy bleeding or concern that the coil has moved or come out. A missed period with pain or a positive pregnancy test also needs prompt assessment.

Seek urgent help for severe abdominal pain, fainting, heavy bleeding with weakness or fever with pelvic pain. Do not try to push a displaced device back into place.

Ask which hormonal coil suits your bleeding and contraception goals, how insertion will be managed, what changes to expect and how to recognise infection or displacement. Discuss alternatives if you have uterine fibroids, adenomyosis, endometriosis or a history of anaemia.
