Premenstrual problems

For most females with premenstrual syndrome (PMS), symptoms such as abdominal bloating, breast tenderness, headache, anxiety, irritability and experiencing the blues are minor and short-lived.

But a small number of females have severe and disabling symptoms that disrupt their studies, jobs, relationships or other areas of their lives. At that point, PMS may cross the line into premenstrual dysphoric disorder (PMDD) — a type of depression that generally requires treatment.

The exact interaction between depression and PMS remains unclear. It's possible that cyclical changes in estrogen, progesterone and other hormones can disrupt the function of brain chemicals such as serotonin that control mood. Inherited traits, life experiences and other factors appear to play a role.
