Hormones and cycles · For ages 13–17
PMOS
PMOS is a condition that may affect hormones, periods, skin, hair growth, metabolism and mental wellbeing.
PMOS stands for polyendocrine metabolic ovarian syndrome. You may also encounter the name PCOS, which is still used in much international research and information.
More than just the ovaries
PMOS affects several systems in the body. The condition is therefore about more than cysts or ovaries.
Periods may become irregular
Some people with PMOS have infrequent, irregular or absent periods.
Skin and hair may change
Some people develop increased facial or body hair, acne or other skin changes.
Body size does not determine the diagnosis
You can have PMOS at any body size. The condition can look different from one person to another.
How is it assessed?
A doctor asks about your periods, skin, hair growth, medicines and other health factors, and considers relevant tests. Several conditions can cause similar symptoms. PMOS, previously called PCOS, is therefore not diagnosed on the basis of a single spot, body size or one test result.
In adolescents, an individual assessment of persistent menstrual irregularities and signs of increased androgen activity is required after other causes have been considered. Androgens are a group of hormones that everyone has. Which cycle changes are relevant depends partly on how long it has been since your first period.
Puberty must be considered when assessing teenagers
Both acne and irregular periods are common during puberty. Different diagnostic considerations are therefore used for teenagers than for adults. Ovarian appearance on ultrasound and an AMH blood test are not recommended as diagnostic criteria for this condition in adolescents.
If the findings are unclear, a doctor can arrange follow-up rather than diagnose the condition immediately. You can receive help with troublesome symptoms while your development is monitored. Ask for a plan that also addresses how you are feeling, without focusing solely on weight or appearance.
What next?
One change alone does not mean you have PMOS
Irregular periods, acne or hair growth can have several explanations. If several changes happen together or worry you, you can seek an assessment.
