Abnormal uterine bleeding (AUB) is a common gynecological concern that affects women at different stages of life, from adolescence to menopause. It refers to bleeding from the uterus that differs from a normal menstrual cycle in timing, duration, or amount. While occasional changes in menstruation can occur, persistent or heavy bleeding should never be ignored. Understanding the causes, diagnostic process, and treatment options is essential for protecting reproductive health and preventing complications.

What Is Abnormal Uterine Bleeding?

Abnormal uterine bleeding is defined as any vaginal bleeding that deviates from normal menstrual patterns. This may include excessively heavy periods, bleeding between cycles, prolonged menstruation, or bleeding after menopause. AUB is a symptom rather than a disease and can result from hormonal imbalances, structural abnormalities, or underlying medical conditions. Identifying the pattern and frequency of bleeding helps doctors determine whether the bleeding is abnormal and requires further evaluation.

Common Symptoms of Abnormal Uterine Bleeding

Symptoms of abnormal uterine bleeding vary depending on the cause but often include unusually heavy menstrual flow that requires frequent pad or tampon changes. Some women experience periods lasting longer than seven days or bleeding between periods. Spotting after intercourse or postmenopausal bleeding are also concerning signs. Additional symptoms such as fatigue, dizziness, or shortness of breath may occur due to anemia caused by chronic blood loss. Any sudden or severe bleeding should be evaluated promptly.

Causes of Abnormal Uterine Bleeding

Abnormal uterine bleeding can occur due to a wide range of causes. Hormonal imbalances are among the most common, particularly during puberty, postpartum periods, or perimenopause. Structural issues such as uterine fibroids, polyps, or adenomyosis can also lead to irregular bleeding. Other causes include polycystic ovary syndrome (PCOS), infections, blood clotting disorders, thyroid problems, and certain medications. In some cases, pregnancy-related complications may also result in abnormal bleeding.

Hormonal Imbalance and Ovulatory Disorders

Hormonal imbalance plays a major role in abnormal uterine bleeding, especially when ovulation does not occur regularly. Without ovulation, estrogen continues to thicken the uterine lining without progesterone balance, leading to unpredictable shedding and heavy bleeding. This is common in teenagers, women with PCOS, and those approaching menopause. Stress, weight changes, excessive exercise, and certain medical conditions can further disrupt hormonal regulation, contributing to irregular menstrual cycles and abnormal bleeding patterns.

Structural Abnormalities of the Uterus

Structural problems within the uterus are another frequent cause of abnormal uterine bleeding. Uterine fibroids are noncancerous growths that can cause heavy or prolonged periods. Endometrial polyps may lead to spotting between periods or after intercourse. Adenomyosis occurs when uterine lining tissue grows into the uterine wall, causing painful and heavy periods. These conditions are usually diagnosed through imaging studies and may require medical or surgical treatment depending on severity.

How Abnormal Uterine Bleeding Is Diagnosed

Diagnosing abnormal uterine bleeding involves a detailed medical history, physical examination, and diagnostic testing. A gynecologist will assess menstrual patterns, pregnancy history, and associated symptoms. Blood tests may be ordered to check hormone levels, anemia, or clotting disorders. Imaging studies such as ultrasound help identify fibroids or polyps. In some cases, endometrial biopsy or hysteroscopy is required to rule out serious conditions, including endometrial cancer, especially in older women.

Treatment Options for Abnormal Uterine Bleeding

Treatment for abnormal uterine bleeding depends on the underlying cause, severity of symptoms, and patient’s age and reproductive goals. Hormonal treatments such as oral contraceptives, progesterone therapy, or hormonal IUDs are commonly used to regulate cycles and reduce bleeding. Non-hormonal medications may help control heavy bleeding. In cases where medical treatment is ineffective, surgical options such as polyp removal, fibroid treatment, or endometrial ablation may be recommended. Individualized treatment ensures optimal outcomes.

Complications of Untreated Abnormal Uterine Bleeding

If left untreated, abnormal uterine bleeding can lead to serious health issues. Chronic blood loss may cause iron-deficiency anemia, resulting in fatigue, weakness, and reduced concentration. Persistent bleeding can also affect emotional well-being, daily activities, and quality of life. In some cases, AUB may be a sign of underlying conditions such as hormonal disorders or malignancy. Early diagnosis and appropriate treatment significantly reduce the risk of long-term complications.
