No. It is a range that mixes a confirmed diagnosis and a provisional estimate. Reilly et al. (2024) separate the two.

Does 1.6% apply to everyone seeking care?

That figure comes from community samples in which the diagnosis was confirmed with prospective records. It is not an estimate for a clinic waiting room or an online group.

Does the app tell me how often this happens to me?

No. The app does not diagnose. A clinician does that, using the pattern over at least two cycles.

How common PMDD is when the diagnosis is confirmed

How common PMDD is depends on how the diagnosis was made. A 2024 meta-analysis makes that difference visible in the numbers. The figure of 3–8% stays on this site, because it mixes the two ways of counting.

What a confirmed diagnosis counts

A 2024 meta-analysis looked at 44 studies with 50,659 participants (Reilly et al., 2024). With a confirmed diagnosis, meaning prospective records, the pooled prevalence was 3.2% (95% confidence interval 1.7–5.9%). In community samples with that confirmed diagnosis it was 1.6% (1.0–2.5%).

What a provisional estimate counts

With a provisional estimate, without two cycles of records, it was 7.7% (5.3–11.0%). Questionnaires that rely on memory count more people than studies that confirm the pattern over two cycles.

Why 3–8% keeps appearing

The figure of 3–8% that is often quoted sits across those ranges. The older figure is a mix of two ways of counting. On this site, 3–8% stays as that familiar range, with this explanation beside it. Why the pattern does not show on a blood test is on hormone sensitivity.
