Overview
Abnormal uterine bleeding (AUB) is vaginal bleeding that differs from your usual menstrual cycle in terms of timing, frequency, length, or quantity. It can develop at any age, from puberty to menopause. While some changes in menstrual bleeding may be temporary, persistent or unusual bleeding should be evaluated by a healthcare professional.
AUB can have a range of causes, including hormonal changes, pregnancy-related illnesses, uterine abnormalities, and underlying medical conditions. Although many of the causes are not serious, some require prompt diagnosis and clinical management. This article covers abnormal uterine bleeding, its potential causes, how it is identified, available management options, and when to seek medical attention.
What is abnormal uterine bleeding?
Abnormal uterine bleeding refers to vaginal bleeding that differs from your usual monthly cycle. This includes changes in the amount of bleeding, how often periods occur, how long they continue, or bleeding outside of your normal menstrual cycle.
Most individuals experience a regular menstrual cycle every 21 to 35 days, with bleeding lasting up to 7 days. However, cycle duration and flow might differ across individuals.
There are several types of abnormal uterine bleeding, including:
- Heavy menstrual bleeding
- Bleeding between periods
- Irregular menstrual periods
- Frequent menstruation (cycles less than 21 days)
- Infrequent periods (cycles lasting more than 35 days)
- Bleeding following sexual intercourse
- Bleeding following menopause

Common causes of abnormal uterine bleeding
| Possible cause | Examples |
|---|---|
| Hormonal changes | Puberty, perimenopause, polycystic ovary syndrome (PCOS), thyroid disorders |
| Pregnancy-related conditions | Early pregnancy bleeding, miscarriage, ectopic pregnancy |
| Uterine conditions | Fibroids, adenomyosis, endometrial polyps |
| Ovulation disorders | Irregular or absent ovulation |
| Medications | Hormonal contraception, anticoagulants, hormone therapy |
| Infections | Pelvic inflammatory disease or infections affecting the reproductive tract |
| Bleeding disorders | Conditions affecting normal blood clotting |
| Cancer or precancerous changes | Endometrial, cervical, or, less commonly, other gynaecological cancers, particularly after menopause |
Signs and Symptoms
Symptoms depend on the underlying cause, but may include:
- Heavy menstrual bleeding
- Bleeding between periods
- Periods lasting more than 7 days
- Passing large blood clots.
- Bleeding following sexual intercourse
- Bleeding following menopause
- Pelvic discomfort or cramps
- Fatigue, weakness, dizziness, or other signs of anaemia
How is abnormal uterine bleeding diagnosed?
Your doctor will analyse your symptoms to figure out the underlying cause and the best management pathway.
- Medical history: Your doctor will enquire about your current health, medications, previous pregnancies, medical issues, and family history.
- Menstrual history: You will be asked questions about your menstrual cycle, including when the bleeding began, how heavy it is, how long it lasts, and if it occurs between periods or after intercourse.
- Pregnancy test: A pregnancy test is routinely used in women of reproductive age to rule out pregnancy-related causes of bleeding.
- Blood tests: Blood tests can assess:
- Iron levels and symptoms of anaemia
- Thyroid function
- Hormone levels
- Blood clotting where appropriate
- Pelvic ultrasound: Pelvic ultrasounds can detect fibroids, polyps, ovarian cysts, adenomyosis, and other structural problems.
- Cervical screening (if applicable): Your doctor may recommend cervical screening in accordance with current guidelines if you show symptoms relating to cervical illness.
- Endometrial biopsy (in specific situations): A small sample of the uterine lining may be collected to check for abnormal cells, particularly in women who experience chronic bleeding or bleeding after menopause.
- Hysteroscopy (if recommended): A hysteroscopy allows a doctor to examine the inside of the uterus using a thin camera and may be recommended if further assessment is needed.

Management options
Treatment depends on the cause of the bleeding, your age, whether you are planning pregnancy, and how severe your symptoms are.
| Management | When it may be recommended |
|---|---|
| Hormonal medicines | For hormonal imbalance, management of irregular periods, or heavy menstrual bleeding |
| Non-hormonal medicines | To reduce heavy bleeding or relieve pain |
| Iron supplements | If heavy bleeding has caused iron deficiency or anaemia |
| Management of underlying conditions | Such as thyroid disease, infections, or bleeding disorders |
| Minimally invasive procedures | For polyps or selected uterine conditions |
| Surgery | For fibroids, severe bleeding, or when other management options have not been effective |
| Specialist care | When complex investigations or advanced treatments are required |

Can lifestyle changes help?
Lifestyle changes improve your general health and manage certain symptoms, but they cannot replace clinical management for underlying medical conditions causing irregular uterine bleeding. Here are some helpful strategies:
- Maintain a healthy weight, as weight fluctuations can disrupt hormonal equilibrium.
- If you are bleeding heavily, you need an iron-rich diet to lower your risk of iron deficiency. Good sources include lean meat, lentils, leafy green vegetables, and iron-fortified cereals.
- Stay hydrated.
- Monitor your menstrual cycle and symptoms using a journal or app.
- Take medicines exactly as prescribed by your doctor.
- Attend regular follow-up sessions to assess your condition and modify treatment as required.
When should you see a doctor?
Arrange a medical evaluation if you encounter any of the following:
- Heavy bleeding that interrupts your regular activities
- Bleeding between periods
- Bleeding following menopause
- Bleeding following sexual intercourse
- Periods lasting more than seven days
- Anaemia symptoms include weariness, dizziness, and weakness
- Chronic pelvic pain or severe cramps
- Irregular bleeding that lasts for months
When is it an emergency?
Seek urgent medical attention immediately if you experience:
- Excessive bleeding, such as soaking through a pad or tampon every hour for several hours
- Severe abdominal or pelvic pain
- Fainting, collapse, or loss of consciousness
- Heavy bleeding during pregnancy or suspected pregnancy
- Symptoms of severe anaemia include shortness of breath, chest discomfort, disorientation, and significant weakness.
If you experience severe, worsening, or life-threatening symptoms, call 000 immediately or attend your nearest Emergency Department (ED). Examples include excessive bleeding (soaking a pad every hour), severe pelvic pain, or loss of consciousness.
Can telehealth help?
Telehealth is a convenient option for appropriate healthcare needs and can complement in-person healthcare. It is not a replacement for face-to-face care. Some health concerns, such as those requiring a physical examination, pregnancy-related complications, or severe bleeding, require an in-person assessment or emergency care.
An online doctor might help with:
- Reviewing your menstruation symptoms and bleeding pattern.
- Assessing potential causes based on your medical history.
- Recommending blood tests or imaging referrals when clinically indicated.
- Prescribing medications where clinically appropriate.
- Referring you to a gynaecologist if additional evaluation is needed.
- Monitoring your symptoms and ongoing treatment through follow-up consultations.
Severe bleeding, potential pregnancy problems, or symptoms needing a physical examination will require a quick in-person evaluation.
