Heavy menstrual bleeding, also known as menorrhagia, is a common concern for many women. Several factors can contribute to unusually heavy periods. One key reason is hormonal imbalances. Specifically, a lack of sufficient progesterone can lead to heavier bleeding. Progesterone is crucial for regulating the menstrual cycle. If your body doesn't release an egg (ovulation), it may not produce enough progesterone, resulting in a thicker uterine lining that sheds more heavily during your period. [Source: Usually, the release of an egg from the ovaries signals the body to make progesterone. Progesterone is the hormone most responsible for keeping periods regular. If no egg is released, the body does not make enough progesterone. This can result in heavy menstrual bleeding or unexpected bleeding between periods. 30-Aug-2023]
Other potential causes include:
- Hormonal imbalances: Fluctuations in estrogen and other hormones can affect the thickness of the uterine lining, leading to heavier bleeding. [Source: If your hormone levels aren't balanced, your body can make the lining too thick, which leads to heavy bleeding when you shed the thicker lining. Feb 13, 2024]
- Uterine fibroids: These noncancerous growths in the uterus can cause heavier and longer periods. [Source: Menorrhagia is heavy or prolonged bleeding during your period. It can be caused by hormone problems or problems with the uterus.]
- Uterine polyps: Similar to fibroids, polyps are small growths that can lead to heavier bleeding. [Source: Menorrhagia is heavy or prolonged bleeding during your period. It can be caused by hormone problems or problems with the uterus.]
- Thyroid problems: An underactive thyroid (hypothyroidism) can disrupt hormone balance and result in heavier or irregular periods. [Source: An underactive thyroid gland (hypothyroidism) may also cause heavy or irregular bleeding.]
- Blood clotting disorders: Certain conditions affecting blood clotting can lead to prolonged or heavier bleeding. [Sources: Mayo Clinic, Cleveland Clinic, CDC]
It's important to note that heavy bleeding can also be a symptom of other underlying medical conditions. If you experience unusually heavy menstrual bleeding, it's essential to consult a healthcare professional for proper diagnosis and treatment. They can help determine the underlying cause and recommend appropriate management strategies.
