What to expect from a hormonal coil for iron deficiency anaemia

The hormonal coil releases progestogen inside the uterus. This can make the womb lining thinner and reduce menstrual blood loss. Less blood loss may help prevent ongoing iron loss, but it does not replace an assessment of why bleeding is heavy or treatment for an existing iron deficiency.

Bleeding patterns commonly change during the first months after insertion. Spotting or unpredictable bleeding may occur before periods become lighter or less frequent. The coil also provides contraception, but it does not protect against sexually transmitted infections.

Your clinician will review your medical history, pregnancy possibility, bleeding pattern and pelvic health before fitting. During insertion, you may feel pressure or cramping. Rest, heat and a suitable pain reliever may help afterwards if your clinician says it is safe for you. Check how to feel for the threads and when the coil should be reviewed.

Keep taking prescribed iron unless your clinician changes the plan. Attend blood-test follow-up if arranged, and record bleeding, fatigue, dizziness or breathlessness so treatment can be adjusted.

Contact a clinician promptly for severe or worsening pelvic pain, fever, unusual or foul-smelling discharge, very heavy bleeding, or concern that the coil has moved. Seek urgent care for fainting, severe weakness, chest pain or difficulty breathing. If you cannot feel the threads, use additional contraception and ask for advice until the position is checked.

Ask whether the coil suits your bleeding pattern, what examination is needed first, which pain relief is appropriate, when to check iron levels, and what changes should prompt a review.
