Blood-loss dominant phenotype
Start with Modules 1, 3, and 5 when heavy flow, clots, flooding, and exhaustion are the main problem and immediate blood-loss control matters most.
Quick Start
Choose the bleeding phenotype in front of you
This course works best when it helps sort the consult by dominant management problem: blood loss burden, pain-plus-bleeding overlap, adenomyosis suspicion, or treatment failure.
Pain-plus-heavy-bleeding phenotype
Start with Modules 2, 4, and 5 when significant dysmenorrhea and bulky/tender uterus features raise adenomyosis suspicion alongside heavy bleeding.
Endometriosis and adenomyosis overlap concern
Start with Modules 2, 4, and 6 when pelvic pain, endometriosis history, and heavy bleeding are coexisting and the issue is joined-up pathway clarity.
Treatment failure or escalation consult
Start with Modules 5 and 6 when first-line treatment has not helped enough, symptoms remain severe, or the next question is specialist referral or surgical discussion.
Clinical Shortcut
Heavy bleeding should be organized around quality-of-life impact and anemia risk first.
NICE defines heavy menstrual bleeding by interference with quality of life. That framing helps prevent undertreatment when patients have normalized a highly disruptive pattern.
Module 1
Heavy Bleeding Phenotype Framing
The key first move is to characterize the bleeding burden properly: duration, flow, flooding, clotting, nocturnal impact, functional impairment, and related pain symptoms.
Bleeding burden
Prolonged bleeding, soaking through products, large clots, frequent night changes, or needing multiple products simultaneously all matter.
Functional burden
Missed work, exercise restriction, travel limitation, sleep disruption, and menstrual anxiety often make the severity clearer than volume language alone.
Pain burden
Significant dysmenorrhea should not be sidelined in the heavy bleeding consult because it may shift the differential toward adenomyosis or endometriosis overlap.
Questions that sharpen the phenotype
- How many days of bleeding, and which days are heaviest?
- Flooding, clotting, night changes, or double protection use?
- How severe is dysmenorrhea and how is it evolving?
- How much does the patient’s function collapse around menses?
Common traps
- Focusing on pain while under-recognizing blood-loss burden.
- Focusing on bleeding while missing the pain phenotype.
- Assuming adaptation means the bleeding is tolerable.
- Using “normal ultrasound” to end the conversation too early.
Module 2
Adenomyosis Suspicion and Differential Thinking
NICE advises transvaginal ultrasound when heavy bleeding coexists with significant dysmenorrhea or a bulky, tender uterus suggesting adenomyosis. The differential still includes fibroids, endometrial pathology, ovulatory causes, bleeding disorders, and endometriosis.
Adenomyosis-clue pattern
Heavy bleeding plus painful periods, pressure, and bulky/tender uterine findings form the classic suspicion pattern.
Endometriosis overlap
When pelvic pain, dyspareunia, bowel or bladder symptoms, or known endometriosis exist, the clinician should keep endometriosis in the pain frame even if adenomyosis is suspected.
Do not over-collapse the labels
Adenomyosis is not covered as a subtype of endometriosis in ESHRE 2022, so overlap should be treated as a practical coexistence problem rather than a terminology shortcut.
Guardrail
Adenomyosis suspicion should widen the pathway, not narrow it prematurely.
The useful move is to improve imaging and treatment specificity, not to erase other contributors such as fibroids, bleeding disorders, or endometriosis-related pain.
Module 3
Iron Loss and Safety
NICE recommends full blood count for all women with heavy menstrual bleeding, in parallel with treatment. Iron loss and anemia risk should be assumed relevant until addressed.
FBC belongs early
Blood loss burden and physiologic burden should be assessed together, not sequentially.
Symptoms that matter
Dizziness, exertional breathlessness, marked fatigue, headaches, palpitations, and poor recovery between cycles.
Why this changes urgency
Significant anemia risk may justify more urgent stabilization of bleeding or faster treatment escalation.
Module 4
Imaging and Investigation Strategy
Investigation should be matched to the history and examination. NICE prefers transvaginal ultrasound for suspected adenomyosis and uses hysteroscopy when cavity pathology is more likely.
Use transvaginal ultrasound when
- Heavy bleeding coexists with significant dysmenorrhea.
- Examination suggests a bulky, tender uterus.
- Adenomyosis is part of the active differential.
Keep other pathways in mind when
- Intermenstrual bleeding suggests cavity pathology.
- Fibroids or uterine mass are suspected.
- Bleeding disorder history or endocrine causes remain plausible.
- Pain features suggest parallel endometriosis assessment is needed.
Module 5
Treatment Sequencing
NICE recommends considering LNG-IUS as first treatment for heavy menstrual bleeding in women with suspected or diagnosed adenomyosis. If unsuitable or declined, move to other pharmacological options.
First-line anchor
LNG-IUS when appropriate, especially when the treatment goal is lighter bleeding with a longer-acting hormonal option.
Alternatives if not suitable
Tranexamic acid, NSAIDs, combined hormonal contraception, and cyclical oral progestogens are the main NICE-listed alternatives for this pathway.
Specialist referral
If treatment fails, is declined, or symptoms remain severe, specialist care may be needed to revisit diagnosis and discuss further pharmacological or surgical options.
Guardrail
The “best” treatment is the one that matches the current dominant goal.
Some patients mainly need bleeding reduction. Others need pain improvement, anemia recovery, contraception, uterine preservation, or more definitive escalation planning.
Module 6
Review Triggers and Workflow
Good heavy bleeding management notes make the plan and the review point visible from the start, especially when pain and fatigue are also major burdens.
What to document clearly
- Bleeding duration, flooding, clots, and night burden.
- Pain severity and whether adenomyosis or endometriosis overlap is suspected.
- FBC and any anemia-risk symptoms.
- Chosen treatment and its intended goal.
- When and how treatment success will be judged.
Signals to reopen the pathway
- Heavy bleeding remains highly disruptive despite first-line treatment.
- Fatigue, dizziness, or functional collapse persist.
- Imaging and symptoms do not line up cleanly and the plan has become vague.
- Pain burden suggests untreated overlap pathology.
