Prolonged Menstrual Bleeding: Causes and Solutions - Obstetrics and Gynecology

Prolonged menstrual bleeding, also known as menorrhagia, can be a concerning issue for many women. It is defined as menstrual bleeding that lasts longer than seven days or is excessively heavy. The causes of prolonged menstrual bleeding can vary widely and may include hormonal imbalances, uterine abnormalities, certain medical conditions, or even lifestyle factors.

One common cause of prolonged menstrual bleeding is hormonal imbalance. Hormones such as estrogen and progesterone regulate the menstrual cycle, and any disruption in their levels can lead to irregularities in bleeding. Conditions such as polycystic ovary syndrome (PCOS) or thyroid disorders can contribute to these hormonal imbalances.

Uterine abnormalities, such as fibroids or polyps, can also lead to prolonged bleeding. These growths can cause the uterus to shed its lining more frequently or heavily than normal. Although you mentioned that a recent ultrasound showed no unusual tumors, it is still possible for smaller fibroids or polyps to go undetected, especially if they are not causing significant symptoms.

Another potential cause of prolonged menstrual bleeding is a bleeding disorder. Conditions such as von Willebrand disease or platelet function disorders can affect the blood's ability to clot, leading to heavier and prolonged menstrual bleeding. If you have a family history of bleeding disorders or have experienced easy bruising or prolonged bleeding from minor cuts, it may be worth discussing this possibility with your healthcare provider.

Infections or inflammation of the reproductive organs, such as pelvic inflammatory disease (PID), can also lead to abnormal bleeding. If you have experienced any unusual discharge, fever, or pelvic pain, it is essential to seek medical attention.

Lifestyle factors, including stress, significant weight changes, or excessive exercise, can also impact menstrual cycles. Stress can affect hormone levels, while significant weight loss or gain can lead to changes in the menstrual cycle.

Given that your menstrual bleeding has persisted for over a month, it is crucial to consult with a healthcare provider. They may recommend further testing, such as blood tests to check for anemia or hormonal levels, or additional imaging studies to evaluate for any underlying conditions that may not have been detected in the previous ultrasound.

In terms of management, treatment options will depend on the underlying cause of the prolonged bleeding. Hormonal therapies, such as birth control pills, can help regulate the menstrual cycle and reduce bleeding. In some cases, medications like tranexamic acid may be prescribed to help reduce heavy bleeding. If structural issues like fibroids or polyps are identified, surgical options may be considered.

In the meantime, it is essential to monitor your symptoms closely. Keep track of the amount of bleeding, any associated symptoms (such as pain or fatigue), and any changes in your menstrual cycle. This information can be valuable for your healthcare provider in determining the best course of action.

In summary, prolonged menstrual bleeding can have various causes, ranging from hormonal imbalances to structural abnormalities. It is essential to consult with a healthcare provider to determine the underlying cause and appropriate treatment. Keeping a detailed record of your symptoms can aid in the diagnostic process and help guide effective management strategies.
