PMS & Menstrual Health

Reviewed by the Nimbera editorial team · Last updated May 2026

Premenstrual syndrome (PMS) affects up to 75% of menstruating women, causing physical symptoms such as bloating, breast tenderness, and cramps, alongside mood changes like irritability and low mood in the 1-2 weeks before menstruation. Dysmenorrhea (painful periods) is the most common gynecological complaint worldwide.

When to see a doctor

Consult a doctor if symptoms significantly disrupt daily life or relationships, if you experience severe depression or thoughts of self-harm premenstrually (possible PMDD), if pain is disabling and unresponsive to OTC treatments, or if symptoms have changed significantly - this may indicate endometriosis or fibroids.
