Uterine Fibroids Symptom Checker

Uterine fibroids are growths of muscle and fibrous tissue that develop in or on the wall of the uterus (womb). They are very common, and they are almost always noncancerous (benign). Fibroids vary enormously — from too small to feel to large enough to change the shape of the uterus — and a person can have one or many. Many fibroids cause no symptoms at all and are found by chance during a routine pelvic exam or a scan done for another reason. When they do cause symptoms, the most common is heavier or longer periods, along with 'pressure' symptoms as a fibroid grows: pelvic fullness, needing to pee often, constipation, or a firm swelling low in the belly. They are a real, treatable condition — not something you're meant to simply put up with.

The most common symptom is heavy or prolonged menstrual bleeding — periods heavy enough to be a nuisance, passing large clots, or bleeding that lasts more than about a week (which, if heavy, can lead to anemia). Others come from a fibroid pressing on nearby organs as it grows: a feeling of pelvic pressure or fullness, needing to urinate often or trouble emptying the bladder, constipation, and sometimes a firm lump you can feel low in the abdomen. Some people also have pain during sex or lower-back pain, and uncommonly fibroids are linked with difficulty getting pregnant or pregnancy complications. Importantly, many people with fibroids have no symptoms — so their absence doesn't mean you don't have them, and their presence doesn't confirm them either.

Not on its own. This checker reads a symptom pattern, and a match means the pattern is reasonable to discuss with a gynecologist — not that you have fibroids. These symptoms are common and have many possible causes: heavy bleeding can come from hormonal changes, polyps, adenomyosis, a bleeding disorder, or other conditions, and pelvic pressure or pain has its own long list of explanations. Only a clinician can work out which one fits, using your history, a pelvic exam, and imaging. So take a match as a good reason to raise it — and a 'doesn't clearly fit' result as reassuring on this check but never a way to rule fibroids out, since many fibroids cause no symptoms at all.

A gynecologist starts with your symptom history and a pelvic exam, during which they may feel a fibroid as a firm, usually painless lump on the uterus. The main imaging test is a pelvic ultrasound, which is quick and painless and can show the size, number, and location of fibroids. If more detail is needed — for example to plan treatment — a clinician may add an MRI, or look inside the uterus with a hysteroscopy or a saline sonohysterogram, and occasionally a laparoscopy. Because heavy bleeding is such a common symptom, they may also run blood tests to check for anemia. The point is that fibroids are diagnosed and measured by a clinician — a self-checker can only tell you whether the conversation is worth having.

Bleeding heavy enough to soak through a pad or tampon every hour for a few hours in a row, sudden and severe pelvic or abdominal pain, or feeling dizzy, faint, or lightheaded (or your heart racing) are not what this checker is for and should be treated as urgent. Very heavy blood loss can cause dangerous anemia, and sudden severe pain can signal a problem that needs immediate care. If any of those apply, go to urgent care or an emergency room now, or call your local emergency number. This tool is for ongoing, everyday symptoms — not for acute heavy bleeding or severe pain, which always warrant prompt in-person evaluation.
