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.
