Cause Fibroids
Can FIBROIDS cause heavy periods?
Abnormal uterine bleeding, heavy menstruation or menorrhagia is usually the result of a hormonal imbalance in adolescents during the years following the onset of menstruation, or in women who are approaching menopause.
Menstruation is often irregular or heavy during these times because, depending on hormonal levels, the ovaries may or may not release an egg. Another common cause of abnormal uterine bleeding is fibroid tumors.
Other causes of excessive bleeding that your doctor should consider include:
* Fibroids
* Endometriosis
* Cervical or endometrial polyps
* Lupus
* Pelvic inflammatory disease (PID)
* Cervical cancer
* Endometrial cancer.
Women using intrauterine devices (IUDs) for birth control, may also experience excessive or prolonged periods. If you experience menorrhagia while using an IUD, the IUD should be removed and replaced with an alternative birth control method.
I would recommend consulting with your doctor/gynaecologist for further evaluation. They will need to run some tests in order to properly diagnose you with what could be the cause of this.
Good luck
