Current guidelines for diagnosing PMS or PMDD require patients to complete a three month symptom log prior to diagnosis. A pattern of cyclical symptoms that begin after ovulation and end when menstruation starts can signal that a diagnosis of PMS or PMDD is correct.

The Symptoms of PMDD
Because the symptoms associated with menstrual cycle disorders often mimic the signs and symptoms of other diseases or conditions, getting a correct diagnosis is imperative. Diagnosing the cause of menstrual cycle disorders is often a process of elimination and ruling out other diseases such as clinical depression, anxiety disorders, endocrine system disorders such as thyroid diseases or polycystic ovary syndrome (PCOS), and pelvic health diseases.

Blood and lab work including a pregnancy test in premenopausal women is normally the first diagnostic tool ordered by your physician. Other diagnostic tools and procedures that your doctor can utilize include endometrial biopsy, diagnostic hysteroscopy, and ultrasounds. Which diagnostic measure your physician chooses depends on your age, symptoms, and medical history.
