Menstrual disorders

Menstrual disorders refer to deviations from a normal menstrual cycle — either the amount of bleeding, the duration, or the length of the cycle changes. The most common symptoms are irregular periods, bleeding that is heavier or lighter than usual, and periods that are absent or occurring more frequently. In young people, menstrual disorders are fairly common because the menstrual cycle often takes time to settle during the first few years. Irregularity is also common around menopause due to hormonal changes in the body.

In Finland, the most common causes of menstrual disorders are problems with ovulation, stress, significant weight loss, heavy exercise, certain conditions (such as thyroid problems or PCOS), and certain medications. Often the cause is benign, but sometimes menstrual disorders can be a sign of an underlying disease.

It is concerning if menstrual bleeding is very heavy, continues for a long time, stops completely without a clear reason, or is associated with severe pain or general symptoms such as fatigue or weight loss. In that case, it is important to seek assessment by a healthcare professional so that any causes requiring treatment can be identified. A professional can also help if menstrual disorders are affecting daily life.
