Abnormal Uterine Bleeding
There are many different causes for abnormal bleeding in women. The typical menstrual cycle in adults is approximately 21 to 35 days. There can be more variability in the first 10 years after the period starts and the 10 years before menopause (average age of menopause in the US is 51.5years). Common causes for abnormal bleeding include hormonal irregularities, concurrent medical conditions such as thyroid disorders, structural abnormalities (fibroids and polyps), the use of certain medications, infection, pregnancy, and neoplasm. The typical work-up for abnormal bleeding includes a complete history and physical. At that time it can be determined whether lab work, ultrasound, or a biopsy needs to be done.
