The diagnosis of PMS at the Pope Paul VI Institute includes the following list of symptoms: irritability, breast tenderness, bloating, weight gain, carbohydrate craving, crying easily, depression, headaches, fatigue and insomnia. The important aspect of diagnosis is that these symptoms must begin at least four days prior to the onset of menses. If they occur within three days of the onset of menses, they are considered to be normal premenstrual molimina. In addition to these 10 core symptoms, other symptoms have also been documented in this group of patients.
