Among women who discontinue intrauterine device (IUD) use within the first year in India, what is the most common reason for discontinuation?

Explanation

## Most Common Reason for IUD Discontinuation in First Year **Key Point:** Excessive menstrual bleeding and dysmenorrhea account for approximately 40–50% of all IUD discontinuations within the first year in India, making it the single most common reason for method failure and user dissatisfaction. ### Epidemiology of IUD Discontinuation Discontinuation rates vary by reason: | Reason for Discontinuation | Frequency (%) | Timing | Mechanism | | --- | --- | --- | --- | | Menorrhagia & dysmenorrhea | 40–50 | 3–6 months | Copper-induced endometrial inflammation | | Expulsion | 5–10 | 3–12 months | Uterine contractions, nulliparity | | Desire for pregnancy | 10–15 | Variable | Planned pregnancy | | Perforation | <1 | Insertion/early | Operator error or uterine anomaly | | Infection/PID | 2–5 | 3–12 months | Ascending infection | **High-Yield:** Menorrhagia and dysmenorrhea are the leading medical reasons for discontinuation. This is NOT a device failure but a side effect that drives user dissatisfaction and non-continuation. ### Mechanism of Menorrhagia with Copper IUD 1. Copper ions trigger local endometrial inflammation 2. Increased prostaglandin production (PGE~2~, PGF~2α~) 3. Enhanced myometrial contractility → dysmenorrhea 4. Increased endometrial vascularity → menorrhagia (30–50% increase in menstrual flow) 5. User perceives bleeding as excessive → discontinuation ### Clinical Pearl **Warning:** Do not confuse discontinuation *reasons* with device *failures*: - **Discontinuation** = user stops using the method (often due to side effects) - **Device failure** = unintended pregnancy while in situ (rare, <1%) Menorrhagia is a **side effect-driven discontinuation**, not a mechanical failure. Expulsion and perforation are mechanical failures but occur at much lower rates. ### Management Strategy To reduce discontinuation due to menorrhagia: - Counsel women preemptively about expected increase in menstrual flow - Offer NSAIDs (mefenamic acid 500 mg TDS during menses) to reduce bleeding and pain - Consider levonorgestrel IUD (Mirena) as alternative if copper IUD side effects are intolerable - Reassure that bleeding typically stabilizes by 3–6 months **Mnemonic:** **MEDIC** for common IUD discontinuation reasons: - **M**enorrhagia & dysmenorrhea (most common) - **E**xpulsion - **D**esire for pregnancy - **I**nfection/PID - **C**omplication (perforation, rare) [cite:Park 26e Ch 6]
