Why Does PMS Happen?

Premenstrual Syndrome (PMS) is triggered by the rapid decline of progesterone and estrogen in the 7 to 10 days before your period. This hormonal drop directly impacts brain neurotransmitters, particularly serotonin, leading to mood swings, sugar cravings, and sleep changes.

Top 10 PMS Symptoms

  1. Abdominal Cramping: Caused by inflammatory prostaglandins contracting uterine muscles.
  2. Bloating & Fluid Retention: High aldosterone and progesterone fluctuations.
  3. Breast Tenderness: Estrogen and progesterone stimulation of breast glandular tissue.
  4. Fatigue & Sleep Disruption: Shifts in core body temperature and REM sleep cycles.
  5. Mood Swings & Irritability: Transient serotonin drops.
  6. Sugar & Carb Cravings: Higher caloric baseline needs during the luteal phase.
  7. Headaches & Migraines: Sudden estrogen withdrawal.
  8. Hormonal Acne Breakouts: Androgen ratio rise stimulating sebum production.
  9. Digestive Changes: Prostaglandin impact on intestinal motility.
  10. Joint & Muscle Aches: Systemic inflammatory signaling.
