Menstrual irregularities
Disease Information
In-Depth
What are the symptoms of menstrual irregularities?
If your daughter has dysfunctional uterine bleeding, she may notice:
- bleeding or spotting from the vagina occurs between periods
- menstrual periods may be less than 28 days, or more than 35 days apart
- the time between each cycle changes each time
- the need to change her pad or tampon during the night or every few hours
- bleeding that lasts for more than seven days
What causes menstrual irregularities?
Conditions that cause a lack of ovulation could be the culprit of menstrual irregularities or dysfunctional uterine bleeding. Common causes include:
- eating disorders
- weight changes
- athletic competition
- chronic illnesses
- drug abuse
- endocrine disorders
- Polycystic ovary syndrome (PCOS)
If your daughter has a vertical or complete vaginal septum, she has two openings to her vagina, and this may prevent one tampon from stopping the flow of blood.
