Abnormaluterine bleeding occurs when bleeding differs from the usual menstrual pattern in terms of timing, amount, or duration. Some women may experience heavy bleeding during periods, bleeding between cycles, after intercourse, or even post-menopause.
Abnormal uterine bleeding isn't always indicative of a severe condition. It can be due to hormonal changes, medication use, or various health issues. Persistent or recurrent bleeding warrants medical evaluation to determine the cause and appropriate treatment.
Main Causes of Abnormal Uterine Bleeding:
Hormonal Imbalances
Imbalances between estrogen and progesterone are common culprits for abnormal uterine bleeding, causing irregular menstruation or increased bleeding. These imbalances are frequent during puberty and near menopause.
Uterine Fibroids
Fibroids are non-cancerous growths in or on the uterus that can lead to heavy menstruation, prolonged periods, or inter-cycle bleeding.
Uterine Polyps
Small polyps within the uterine lining may cause abnormal bleeding, particularly after intercourse or between periods.
Endometriosis
Endometriosis can disrupt menstrual cycles, cause severe period pain, and result in abnormal bleeding for some women.
Adenomyosis
This condition involves endometrial tissue growing into the uterine muscle, potentially leading to heavy, prolonged periods and severe menstrual pain.
Pregnancy and Its Complications
Early pregnancy bleeding may relate to implantation, but it can also indicate miscarriage or ectopic pregnancy, requiring urgent medical evaluation.
Polycystic Ovary Syndrome (PCOS)
PCOS can disrupt ovulation, causing irregular menstrual cycles or abnormal bleeding.
Contraceptive Use
Hormonal contraceptives or intrauterine devices might cause irregular bleeding, especially during initial months of use.
Thyroid Disorders
Hyperthyroidism or hypothyroidism can affect menstrual regularity, potentially leading to abnormal bleeding.
Blood Clotting Disorders
Inherited or acquired bleeding disorders may increase menstrual flow or cause abnormal uterine bleeding.
Medications
Blood thinners and some hormonal treatments can alter bleeding quantity or duration.
Endometrial or Cervical Cancer
In some cases, particularly post-menopause, abnormal bleeding may signal endometrial or cervical cancer, necessitating medical attention.
Symptoms Accompanying Abnormal Uterine Bleeding
Abnormal uterine bleeding could be associated with heavy periods, inter-cycle bleeding, post-coital bleeding, post-menopausal bleeding, pelvic pain, severe cramps, fatigue, anemia-related dizziness, or shortness of breath.
Diagnosing Abnormal Uterine Bleeding
Diagnosis involves medical history, physical exams, possibly blood tests, pregnancy tests, ultrasounds, hysteroscopy, or endometrial biopsies to investigate abnormalities.
Treatment for Abnormal Uterine Bleeding
Treatment depends on the root cause and may involve hormonal medications, treatments to reduce bleeding, addressing thyroid disorders, polyp or fibroid removal, surgical interventions, or cancer treatments.
When to Consult a Doctor?
Seek medical attention if bleeding is excessive, requires frequent pad changes, persists long-term, occurs post-menopause, accompanies severe pain or dizziness, occurs during pregnancy, or if it recurs unusually.
