When Bleeding Changes, The Reason Matters
Heavy periods, prolonged bleeding, bleeding between periods, or unexpected changes in your usual cycle can have many possible causes. A thoughtful AUB evaluation looks beyond the bleeding itself — to understand the pattern, identify possible causes, and choose treatment appropriate to your symptoms, health, and reproductive stage.
“What Kind of Bleeding Are You Experiencing?”
Heavy
Much heavier than usualLong
Lasts unusually longFrequent
Periods coming too oftenInfrequent
Periods arriving far apartBetween
Bleeding between periodsUnexpected
After sex or unexpected timingNew
Sudden change from usual patternHeavy
Bleeding that’s noticeably heavier than your usual — soaking through protection quickly, passing large clots, or feeling like it’s “taking over.” Possible causes range from fibroids and adenomyosis to ovulatory dysfunction and bleeding disorders. Treatment depends entirely on which is behind it.AUB Can Involve Six Dimensions
Amount
How much bleeding occurs
Duration
How long it continues
Frequency
How often it occurs
Regularity
Is the pattern predictable?
Timing
Unexpected occurrence?
Impact
Affecting health or daily life?
“Abnormal” Does Not Mean “Dangerous”
The term “abnormal uterine bleeding” describes a bleeding pattern that is outside the expected menstrual pattern — or otherwise clinically noteworthy. It does not automatically mean:
AUB Is a Description, Not a Diagnosis
AUB tells us what the bleeding pattern looks like. The next clinical question is always the same:
Why is it happening?
AUB itself branches into several broad categories of possible cause:

A structured framework doctors use to classify the possible causes of abnormal uterine bleeding. Click each letter to explore.
Polyps
Adenomyosis
Leiomyoma
Malignancy & Hyperplasia
Coagulopathy
Ovulatory Dysfunction
Endometrial
Iatrogenic
Not Otherwise Classified
P — Polyps
Endometrial or cervical polyps — small growths that can contribute to irregular bleeding or spotting, particularly bleeding between periods.
Heavy Is Not Just About Counting Pads
Clinical assessment considers real-life impact, not just a number.
Structural & Related Causes
The most common structural and clinical conditions associated with abnormal bleeding.
Fibroids (Leiomyoma)
Structural growths of the uterine muscle. Symptoms depend heavily on location — submucosal, intramural, or subserosal.
Polyps
Small endometrial or cervical growths that can cause spotting, irregular bleeding, intermenstrual bleeding, or postmenopausal bleeding.
Adenomyosis
Tissue similar to the uterine lining growing within the uterine muscle wall, associated with heavy periods, painful periods, and pelvic discomfort.
Endometriosis
Distinct from AUB itself, but pelvic pain and menstrual symptoms can overlap. Not every painful period means endometriosis, but persistent pain deserves evaluation.
PCOS / Ovulatory Dysfunction
PCOS can lead to irregular ovulation and irregular menstrual patterns.
“If Pregnancy Is Possible, It Changes the Evaluation”
Pregnancy-Related Bleeding
Abnormal bleeding in someone who may be pregnant can have different causes and may require different assessment — this is why pregnancy possibility is one of the very first things discussed in an AUB consultation.
Medications & Contraception
Bleeding patterns can change with hormonal contraception, intrauterine devices, anticoagulants, and other medicines.
Bleeding Disorders
Some people with heavy menstrual bleeding may have an underlying bleeding disorder. Possible clues include:
When Periods Change in the Years Before Menopause
Not Every Abnormal Bleeding Pattern in Perimenopause Should Simply Be Labelled “Hormonal.”
What has changed?
How heavy is the bleeding?
Is it persistent or recurrent?
Are there other symptoms?
Bleeding After Menopause Is Different
This Should Always Be Evaluated.
Bleeding after menopause should be medically evaluated rather than automatically attributed to hormonal fluctuation. Potential causes range from benign conditions to conditions that require urgent exclusion — this is a clinically prominent priority, not something to “wait and see” about.

Six Steps From Bleeding to Treatment
Tests Should Answer Questions
Organized by what they’re actually trying to find out — not ordered as a routine maximal panel.
Pregnancy Testing
Excludes or considers pregnancy as part of the clinical picture.
Blood Tests
CBC, iron studies, thyroid testing, coagulation testing, and selected hormone tests as relevant.
Ultrasound
Assesses uterine structure, endometrial thickness, and ovarian findings.
Endometrial Sampling
May be indicated in specific circumstances, particularly for certain age groups or risk factors.
Not Everyone Needs Every Test. Investigations Are Chosen Based on Risk Factors, Age, and Clinical Presentation.
Treatment Should Match the Cause
| Cause Category | Treatment Direction |
|---|---|
| Ovulatory dysfunction | Hormonal regulation, address underlying cause |
| Fibroids | Medical or procedural, depending on symptoms and goals |
| Polyps | Removal when appropriate |
| Adenomyosis | Symptom management ± other options depending on severity |
| Bleeding disorders | Coordinated management with haematology when needed |
| Medication-related | Review and adjustment with prescribing clinician |
| Anaemia from AUB | Address bleeding + iron management when appropriate |
| Postmenopausal bleeding | Prompt evaluation to determine appropriate next steps |
What Hormonal Treatment Can Do
What It May Do
- Regulate bleeding patterns
- Reduce menstrual blood loss
- Suppress ovulation in selected circumstances
- Support endometrial stability
What It Does NOT Necessarily Mean
Being prescribed hormonal treatment for AUB doesn’t automatically mean something is seriously wrong — it’s a common, well-established management tool.
When Medicines Aren’t the Whole Answer
Procedures may be considered when structural causes are present, symptoms are significant, medical treatment hasn’t worked, or a tissue diagnosis is needed.
Hysteroscopic Procedures
Diagnostic or therapeutic procedures performed through the vagina and cervix, without external incisions.
Endometrial Ablation
A procedure that reduces the endometrial lining, considered in selected patients not planning future pregnancy.
Myomectomy
Fibroid removal while preserving the uterus, when fibroids are the identified cause.
Hysterectomy
A definitive but irreversible option, typically discussed when other treatments haven’t controlled symptoms or fertility isn’t a priority.
Surgery Is Never Presented as the Automatic First Step.
When Bleeding Needs Urgent Attention
Very heavy bleeding
Feeling faint or fainting
Severe pelvic pain
Rapidly worsening symptoms

Your questions
Let’s Separate Fact From Fear
Click or tap each card.
“Abnormal bleeding always means cancer.”
Most causes of AUB are benign — cancer is one possibility among many, and is specifically why appropriate evaluation matters.
“Irregular bleeding in perimenopause is always just hormones.”
While hormonal shifts are common, persistent or unusual bleeding in perimenopause still deserves individual evaluation.
“Heavy bleeding is just something women have to live with.”
Persistent or significant heavy bleeding is a medical symptom that deserves evaluation and treatment — not silent endurance.
“You only need an ultrasound if bleeding is really severe.”
Investigations are chosen based on risk factors, age, and presentation — not severity alone.
“Postmenopausal spotting is nothing to worry about.”
Any bleeding after menopause should be evaluated — it’s never something to dismiss, whatever the eventual cause turns out to be.
“Hormonal treatment for AUB means something is seriously wrong.”
Hormonal treatment is a common, well-established, safe tool for regulating bleeding — not a marker of severe disease.
