The simple idea (no memorising)
A fibroid (leiomyoma) is a firm, non‑cancerous knot growing from the womb's muscular wall. They're very common in the reproductive years and tend to grow while estrogen is around (and shrink after menopause).
Location is everything:
A small submucosal fibroid (poking into the cavity) can cause heavy bleeding and fertility trouble, while a large subserosal one (bulging outward) may cause almost nothing. So: location beats size.
Common symptoms
Most fibroids are silent. When they speak, the classic complaint is heavy menstrual bleeding (sometimes with anaemia from blood loss). Large ones can press on neighbours — causing a feeling of pressure, constipation, or needing to pass urine often.
One special exam favourite
In pregnancy, a fibroid can outgrow its blood supply and undergo red degeneration — sudden localised pain, sometimes with a low fever. Remember: pregnant + painful fibroid → red degeneration.
How they're managed
- No symptoms → often just watch.
- Symptoms → medicines to control bleeding, or a procedure.
- Wants future fertility → lean toward myomectomy (remove the fibroid, keep the womb).
- Family complete and symptoms severe → hysterectomy may be an option.
The real choice depends on age, symptoms, number, size, location and her wishes — never on age alone.
Why it matters
Fibroids are one of the most common reasons for heavy periods and gynaecological surgery. The single most useful insight — symptoms track location, not size — prevents a lot of wrong assumptions.
