Abnormal menstrual bleeding can result due to a number of conditions such as uterine fibroids, polyps, adenomyosis of the womb, thickening of the womb lining or, rarely, endometrial or cervical cancer. How can you know whether your irregular or heavy periods are a symptom of something more serious?
An excellent article written in plain English by Consultant Gynaecologist, Mr Ertan Saridogan, 
describes the causes of abnormal vaginal bleeding and the additional symptoms they cause. The heavy periods discussed by Mr Saridogan include von Willebrand Disease, hormonal disorders and problems with blood clotting or blood thinning medication.
