Glengarry Private Hospital

Premenstrual syndrome (PMS) or premenstrual tension (PMT refers to physical and emotional symptoms occurring 1 to 2 weeks before the period starts. PMS | PMT can be very severe. The probable cause is a drop in hormones or a change in hormone ratios before the period starts. A lot is still unknown about the condition.



Symptoms of PMS | PMT include: acne, anxiety, back pain, bloating, change in appetite, clumsiness, constipation, depression, diarrhoea, dizziness, headache, irritability, joint pain, lethargy, low libido, mood swings, nervousness, sleep problems, swelling, tender breasts,  and tiredness.


It’s very important to rule out other causes of premenstrual symptoms. For instance, endometriosis can cause discomfort, bloating and other symptoms before menstruation. Thyroid disorders can mimic the other symptoms, as can depression. Your GP can consider these diagnoses. Endometriosis can be ruled out by performing a laparoscopy.
