Heavy menstrual bleeding with persistent intermenstrual bleeding and risk factors for endometrial pathology —

HardMenstrual CycleHeavy menstrual bleeding with persistent intermenstrual bleeding and risk factors for endometrial pathologyDFSRH

A 39-year-old nulliparous woman with polycystic ovary syndrome and type 2 diabetes has a BMI of 39 kg/m². She usually menstruates every 8–12 weeks, with each episode lasting 8–10 days and substantially affecting her quality of life. During the past 7 months she has also developed persistent intermenstrual spotting. Tranexamic acid has reduced the volume of her heavier bleeding but not the spotting. Pregnancy testing and vaginal nucleic acid amplification tests for Chlamydia trachomatis and Neisseria gonorrhoeae are negative. Cervical screening is up to date, and speculum examination shows a normal cervix. Bimanual examination identifies a normal-sized, mobile, non-tender uterus with no adnexal mass. Transvaginal ultrasonography performed 6 weeks ago showed no fibroid, polyp or adnexal lesion; the endometrium measured 7 mm. She would like a 52 mg levonorgestrel intrauterine device if clinically appropriate. Which is the most appropriate next management strategy?

Correct answer: C — Arrange outpatient hysteroscopy with endometrial sampling during the procedure

This woman requires outpatient hysteroscopy with endometrial sampling at the same procedure. Persistent intermenstrual bleeding suggests possible intracavitary or endometrial pathology. Her infrequent heavy bleeding, obesity, PCOS and type 2 diabetes further increase concern for endometrial hyperplasia through prolonged periods of limited progestogenic opposition. Her age below 45 years does not negate these symptom-based and metabolic risk factors. A normal transvaginal ultrasound and a 7 mm endometrial measurement do not exclude endometrial pathology in a premenopausal woman; endometrial thickness varies across the cycle and no threshold given here safely replaces histological assessment. NICE recommends outpatient hysteroscopy when heavy menstrual bleeding is accompanied by persistent intermenstrual bleeding or risk factors for endometrial pathology, with biopsy considered during hysteroscopy in high-risk women. Blind biopsy should not be used in this HMB pathway because it may miss focal, potentially treatable lesions. ([nice.org.uk](https://www.nice.org.uk/guidance/ng88/chapter/recommendations?utm_source=openai)) Hysteroscopy without sampling fails to address her hyperplasia risk. Repeat ultrasound based on an arbitrary thickness threshold is insufficient. Immediate LNG-IUD insertion would be reasonable for low-risk HMB without concerning associated features, but investigation should precede empirical treatment in this case. The LNG-IUD can subsequently be considered once the cavity and histology have been appropriately assessed.
