Premenstrual syndrome is a problem that manifests itself, among other things, in abdominal pain, breast tenderness and headaches. In many cases, other problems are also possible, such as irritability, mood swings or sleep disturbances. The condition is encountered in a variety of women - both in perfectly healthy women and in patients who are struggling with a variety of medical conditions. PMS is also experienced by patients with bipolar disorder - interestingly, in such women, premenstrual syndrome can affect the course of BPAD.

Premenstrual syndrome occurs because of cycle-related fluctuations in concentrations of sex hormones. Changes in their concentrations can result in PMS symptoms in women, but also affect the psyche of patients suffering from bipolar disorder. It appears that depressive episodes are more frequent and manic episodes less frequent in BPAD patients who are also struggling with premenstrual syndrome. In these women, the intervals between BPAD episodes may be shorter and the intensity of symptoms may be greater than in patients who do not have PMS along with their bipolar disorder.

Given the above, it seems obvious that BPAD patients should try to lead a lifestyle that minimises the possibility of PMS symptoms. To this end, it is advisable to ensure an adequate amount of sleep, or during the premenstrual period, to avoid caffeine and sweets.
