About Women's Health
Readers here learn to tell a defined clinical stage from a marketing category, to read a lab result for what it can actually establish, and to weigh treatment options against the evidence that supports them. Start with the linked guides below and follow the path that matches your question.
This section covers the menopausal transition the way it is defined in the clinical literature rather than the way it is described in marketing. You will find what the staging criteria actually say, how long each stage typically lasts, which symptoms are genuinely attributable to changing hormones, and which are commonly attributed to them without good evidence.
