Module 21 reads Stina’s years of abnormal uterine bleeding and her infertility not as bad luck but as two forces of her disease: pelvic adhesions from recurrent FMF peritonitis, and chronic inflammation disrupting the hormonal rhythm of the cycle.

ARRIVED HERE FROM A SEARCH?

If you were looking up one of these, you’re in the right place.

This page belongs to a teaching case built around familial Mediterranean fever (FMF), an IL-1β-driven autoinflammatory disease. If you found it searching one of these findings, it is a valid, evidence-anchored starting point.

What this case is

Looking back, Stina’s reproductive history carried the same fingerprints: years of abnormal uterine bleeding no one tied to anything systemic, and infertility when she and her partner tried to conceive. ‘Heavy periods and trouble conceiving — that’s just bad luck, or stress.’ Module 21 reads two forces at work. Stina is me.

Why the logic holds

FMF is associated with infertility/subfertility, and recurrent peritonitis leaves pelvic and tubal adhesions as a documented mechanism.1,2,3 Chronic inflammatory cytokines also suppress the hypothalamic-pituitary-gonadal axis and disturb cycling5 (general, flagged). And the reassuring, current evidence: colchicine is safe for fertility, pregnancy, and lactation — controlling FMF is part of protecting fertility, not a threat to it.4

Why it’s useful

If you reached this page searching infertility or abnormal bleeding with recurrent pelvic pain, or whether colchicine is safe in pregnancy, that is the page doing its job: treat the inflammation, and keep the colchicine.

Each step of the case, and the literature behind it

Bleeding & infertility

CHART CLUE #19

Abnormal uterine bleeding and infertility in a woman with recurrent pelvic peritonitis are adhesions plus inflammation-disrupted cycling — not unexplained bad luck.

SUPPORTING EVIDENCE

Trouble conceiving

ADHESIONS

FMF-associated infertility is documented; adhesions from recurrent peritonitis distorting the tubes are a key mechanism.

SUPPORTING EVIDENCE

Disrupted cycle

HPG AXIS

Chronic inflammatory cytokines suppress the hypothalamic-pituitary-gonadal axis and disturb menstrual cycling.

SUPPORTING EVIDENCE

Can she take colchicine?

PREGNANCY

Colchicine is safe for fertility, pregnancy, and lactation; controlling FMF protects rather than harms fertility.

SUPPORTING EVIDENCE

A NOTE FROM THE AUTHOR

Stina is not a composite. Stina is me. The heavy bleeding and the years of trying to conceive were mine, and ‘just bad luck, or stress’ never once asked whether the disease that scarred the rest of me had reached here too.

This page holds both truths at once. The lived experience is real; the research support is what earns the case a place in a science course, and the HPG-axis mechanism is flagged as general. If you are a clinician who arrived from a patient, treat this as a validated starting point that respects the patient’s experience and then hands you the literature — and reassure them that colchicine is safe in pregnancy.
