Since premenstrual syndrome (PMS) includes a wide range of symptoms, a specific diagnosis may be difficult to make. Therefore, it is necessary to keep a record of your monthly physical and emotional symptoms. This will help your doctor to make an accurate diagnosis. The symptoms will most likely occur 1-2 weeks before you menstruate. When symptoms occur at about the same time each month, PMS is likely the condition.
Your doctor will ask you about your symptoms and medical history. The timing of your symptoms and their impact on daily activities are very important to consider. You may be given a questionnaire or a chart to keep track of your discomforts.
Physical Examination and Tests
A complete physical exam will provide important information. Although there is no single finding that confirms the diagnosis of PMS, your doctor will want to look for signs that may indicate another conditions. Examples include thyroid disorders, diabetes, chronic fatigue syndrome, endometriosis, perimenopause (if you are over 40), or medication side effects.
