Do your periods come too frequently, last longer than usual, or involve unusually heavy bleeding? Have you experienced bleeding between periods, after intercourse, or even after menopause? If yes, you may be experiencing Abnormal Uterine Bleeding (AUB).
Many women consider these symptoms to be a normal part of life and delay seeking medical advice. However, abnormal uterine bleeding can sometimes indicate an underlying health condition that requires timely diagnosis and treatment.
This article explains the causes, symptoms, diagnosis, and treatment options for abnormal uterine bleeding.
What is Abnormal Uterine Bleeding (AUB)?
A normal menstrual cycle typically occurs every 21 to 35 days, with bleeding lasting 2 to 7 days and a moderate amount of blood loss.
Abnormal uterine bleeding occurs when this normal pattern changes. It may include:
- Heavy menstrual bleeding
- Periods lasting longer than 7 days
- Bleeding between periods (intermenstrual bleeding)
- Bleeding after sexual intercourse
- Bleeding after menopause
- Frequent periods occurring less than 21 days apart
- Infrequent periods occurring more than 35 days apart
If you notice any of these symptoms, it is important to consult a gynecologist for evaluation.
Common Causes of Abnormal Uterine Bleeding
Several medical conditions can lead to abnormal uterine bleeding.
1. Hormonal Imbalance
Hormonal imbalance is one of the most common causes of AUB.
The hormones estrogen and progesterone regulate the menstrual cycle. When these hormones become imbalanced, periods may become:
- Heavy
- Irregular
- Prolonged
Hormonal imbalance is commonly seen:
- During adolescence
- In women approaching menopause
- In women with irregular ovulation
2. PCOS (Polycystic Ovary Syndrome)
Women with PCOS often do not ovulate regularly.
Without regular ovulation, the uterine lining continues to build up and eventually sheds irregularly, causing:
- Heavy bleeding
- Prolonged periods
- Irregular menstrual cycles
3. Uterine Fibroids
Fibroids are non-cancerous growths that develop inside the uterus.
Depending on their size and location, they may cause:
- Heavy menstrual bleeding
- Longer periods
- Pelvic pressure or pain
- Anemia due to excessive blood loss
4. Adenomyosis
Adenomyosis occurs when the tissue lining the uterus grows into the muscular wall of the uterus.
Common symptoms include:
- Heavy menstrual flow
- Severe menstrual cramps
- Enlarged uterus
- Chronic pelvic pain
5. Thyroid Disorders
Both hypothyroidism and hyperthyroidism can affect hormone balance and disrupt the menstrual cycle, resulting in:
- Irregular periods
- Heavy bleeding
- Longer menstrual cycles
6. Endometrial Polyps
Endometrial polyps are growths inside the uterine cavity.
They may cause:
- Heavy periods
- Spotting between periods
- Bleeding after intercourse
7. Bleeding During Pregnancy
Any vaginal bleeding during pregnancy should always be evaluated by a doctor.
Possible causes include:
- Threatened miscarriage
- Ectopic pregnancy
- Placental abnormalities
Pregnant women experiencing bleeding should seek immediate medical attention.
8. Endometrial Hyperplasia or Endometrial Cancer
Although less common, these are important causes of abnormal uterine bleeding.
The risk is higher in women who:
- Are over 45 years of age
- Have obesity
- Have PCOS
- Experience bleeding after menopause
Early diagnosis plays a crucial role in successful treatment.
9. Medications
Certain medications can also contribute to abnormal bleeding, including:
- Hormonal therapies
- Blood-thinning medications (anticoagulants)
If you notice changes in your menstrual cycle after starting a new medication, discuss it with your doctor.
When Should You Consult a Doctor?
Do not ignore abnormal bleeding. Consult your gynecologist if you experience:
- Heavy menstrual bleeding
- Bleeding lasting more than 7 days
- Bleeding between periods
- Bleeding after menopause
- Bleeding after intercourse
- Very frequent or infrequent periods
- Any unusual change in your normal menstrual pattern
Early evaluation can help identify the underlying cause before complications develop.
How is Abnormal Uterine Bleeding Diagnosed?
Your doctor will begin with a detailed medical and menstrual history, followed by a physical examination.
Further investigations may include:
Blood Tests
These may include:
- Hemoglobin levels to check for anemia
- Thyroid function tests
- Other hormone tests if needed
Pelvic Ultrasound
Ultrasound helps detect conditions such as:
- Fibroids
- Adenomyosis
- Endometrial polyps
Pap Smear
A Pap smear may be recommended to screen for cervical abnormalities, depending on your age and symptoms.
Endometrial Biopsy
An endometrial biopsy helps rule out:
- Endometrial hyperplasia
- Endometrial cancer
This test is especially important for women with risk factors or persistent abnormal bleeding.
Treatment Options for Abnormal Uterine Bleeding
Treatment depends on the underlying cause, age, future pregnancy plans, and severity of symptoms.
Medications
Medical treatment may include:
- Medicines to reduce menstrual bleeding
- Hormonal therapy
- Progesterone treatment
- Oral contraceptive pills
- Iron supplements to treat anemia
Minimally Invasive Procedures
Some women may benefit from procedures such as:
- Hysteroscopy
- Polyp removal
- Endometrial biopsy
These procedures help diagnose and treat many causes of abnormal bleeding with minimal recovery time.
Surgical Treatment
Surgery may be recommended for women with:
- Large fibroids
- Severe adenomyosis
- Persistent symptoms despite medication
- Structural abnormalities requiring correction
Your gynecologist will recommend the most appropriate treatment based on your condition.
Why Early Diagnosis Matters
Abnormal uterine bleeding is not a disease by itself, it is a symptom that may indicate an underlying medical condition.
Ignoring heavy or irregular bleeding can lead to:
- Anemia
- Chronic fatigue
- Reduced quality of life
- Delayed diagnosis of serious conditions
Early consultation allows timely treatment and helps prevent complications.
Final Thoughts
Changes in your menstrual cycle should never be ignored. Whether it’s heavy bleeding, prolonged periods, spotting between cycles, or bleeding after menopause, abnormal uterine bleeding deserves proper medical evaluation.
Fortunately, most causes of AUB are treatable with medications, minimally invasive procedures, or surgery when necessary. Seeking medical care early can help identify the cause, relieve symptoms, and protect your long-term reproductive health.
If you’re experiencing abnormal uterine bleeding, consult your gynecologist for a thorough evaluation and personalized treatment plan. Early diagnosis is the key to better health and peace of mind.
