What is premature ovarian insufficiency?
Premature ovarian insufficiency (POI) refers to a decline or loss of ovarian function before the age of 40. It is characterized notably by irregular or absent menstrual cycles, accompanied by hormonal changes.
Unlike natural menopause, ovarian activity may fluctuate in some women with POI. Indeed, the term "insufficiency" is now preferred over "ovarian failure" because it better reflects this variability.
What are the possible signs?
Symptoms can vary from woman to woman. Changes in the menstrual cycle are often among the first signs. Other symptoms linked to reduced estrogen levels may also appear, such as hot flashes, night sweats, sleep disturbances, vaginal dryness, or decreased libido. Difficulty conceiving can also lead to a diagnosis.
Causes and associated factors
The causes of POI are diverse. They may be genetic or chromosomal in origin, autoimmune, or result from certain medical or surgical treatments. However, in a significant number of cases, no specific cause is identified.
Why is early diagnosis important?
POI affects more than just fertility. The early decline in ovarian activity and estrogen levels can also have long-term consequences, particularly for bone and cardiovascular health, as well as for sexual health and psychological well-being. Appropriate medical management and follow-up are therefore important.
Lifestyle and nutritional balance
A balanced diet, regular physical activity, quitting smoking, and maintaining a healthy weight are all part of a lifestyle that supports overall health. For women with POI, particular attention should also be paid to bone and cardiovascular health.
What about fertility?
POI can reduce the chances of spontaneous pregnancy, though ovarian function may sometimes be intermittent. If pregnancy is desired, a specialist consultation allows for an assessment of the individual situation and a discussion of the various management options.
In conclusion
Persistent menstrual irregularity or the absence of periods before the age of 40 warrants a medical evaluation. Early diagnosis makes it possible not only to address fertility-related issues but also to implement appropriate monitoring to preserve long-term health and quality of life.
