Overview
Premenstrual dysphoric disorder (PMDD), a severe form of premenstrual syndrome (PMS), is a set of physical or mood-related symptoms that occur before your menstrual period each month. Symptoms begin about 1 to 2 weeks before your period starts and go away in the first few days of your period.
PMDD is related to hormone changes that happen during your menstrual cycle. But doctors don't know why some people have PMDD and others don't.
Symptoms include mood swings, depression, and feeling irritable or anxious. You may also have sore breasts, bloating, or joint or muscle pain.
With PMDD, these symptoms interfere with your life. They may affect your relationships, work, or school.
Home treatments can help you feel better. Regular exercise and healthy eating also can help.
Doctors often prescribe medicines for PMDD. Selective serotonin reuptake inhibitors (SSRIs) and hormonal birth control can relieve symptoms. If these don't help, your doctor may prescribe other medicines.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
