Absent or irregular periods causes
PCOS and Absent or Irregular Periods
PCOS is a common reason for absent, very infrequent, or widely spaced periods. We diagnose it by your symptoms and a small set of tests.
What this usually means
- Periods may be irregular, far apart, or absent for months.
- Some people notice acne, increased facial/body hair, or scalp hair thinning.
- Testing confirms PCOS and checks for other causes that can look similar.
How this is assessed
Assessment usually includes cycle history, symptom review, targeted blood tests, and a pelvic scan when helpful.
Treatment approach
Treatment is tailored to your goals and may include cycle support, help for acne or unwanted hair, and fertility planning where relevant.
Next step: if your periods are absent or very irregular, assessment helps us choose the right pathway for your situation.
