Why does periods have heavy bleeding?

There are several reasons why someone may experience heavy bleeding during their period. Some common causes include:

- Hormonal imbalance: Fluctuating levels of estrogen and progesterone, the hormones that regulate the menstrual cycle, can sometimes lead to heavy bleeding. This is especially common in the first few months after starting a new hormonal contraceptive or during perimenopause.

- Uterine fibroids: Fibroids are non-cancerous growths that can develop in the wall of the uterus. They can sometimes cause heavy bleeding and other menstrual irregularities.

- Adenomyosis: This condition occurs when the tissue that lines the uterus (the endometrium) grows into the muscle of the uterus. It can cause heavy bleeding, pain, and other symptoms.

- Endometriosis: Endometriosis is a condition in which the endometrium grows outside of the uterus, usually in other parts of the pelvic region. It can cause heavy bleeding, pain, and other symptoms.

- Pregnancy complications: Certain pregnancy complications, such as miscarriage, ectopic pregnancy, and gestational trophoblastic disease, can cause heavy bleeding.

- Cancer: In rare cases, heavy bleeding can be a symptom of uterine or cervical cancer.

If you are experiencing heavy bleeding during your period, it is important to see a healthcare provider to determine the cause and get appropriate treatment.
