Premenstrual syndrome hormones: what they mean

During a menstrual cycle, oestrogen and progesterone rise and fall in a changing pattern. PMS symptoms appear in the later cycle for some people as the brain and body respond to these shifts. Chemical messengers involved in mood, appetite, sleep, fluid balance, and pain may also be affected. That is why PMS can include breast tenderness, bloating, headaches, food cravings, low mood, anxiety, or reduced concentration. A blood test is not usually enough to confirm PMS; the timing and repetition of symptoms are often more informative.

Track symptoms daily alongside cycle dates for at least several cycles, noting how they affect sleep, relationships, and work. Consistent sleep, movement, regular meals, and stress-supporting routines may reduce the overall burden. A clinician can review medicines and discuss options that influence the cycle, including the Combined Pill, if it is safe for you. Do not start hormone products or supplements based only on a hormone result or an online symptom list.

Arrange care when symptoms are severe, appear at other points in the cycle, continue after bleeding, or cause significant impairment. New pelvic pain, unusual bleeding, persistent breast changes, thyroid-like symptoms, or a major change in mood may need a different evaluation. Seek urgent help for suicidal thoughts, fainting, sudden severe pain, or possible pregnancy with pain or bleeding.
