What causes PMDD?
Although the precise cause of PMS and PMDD is unknown, it is believed that these conditions result from the interaction of hormones produced by the ovaries at different stages in the menstrual cycle (such as estrogen and progesterone) with the neurotransmitters (chemicals that serve as messengers) in the brain. While the ovarian hormone levels are normal in women with PMDD, it is likely that the brain's response to these normally-fluctuating hormone levels is abnormal.
Most evidence suggests that PMS and PMDD do not result from any specific personality traits or personality types. While stress clearly is associated with PMS and PMDD, it is not considered to be a cause of PMDD. Rather, the associated stress is more likely to be a result of the PMS or PMDD symptoms. Vitamin or other nutritional deficiencies have not been shown to cause PMS or PMDD.
What are the symptoms of PMDD?
Symptoms of PMS and PMDD can be similar but are more intense and debilitating in PMDD. The symptoms of PMDD also may vary among affected women. Some of the most commonly reported symptoms include:
- mood changes,
- abdominal bloating,
- breast tenderness,
- increased appetite,
- oversensitivity to environmental stimuli,
- hot flashes,
- heart palpitations,
- easy crying,
- difficulty concentrating,
- forgetfulness, and
- gastrointestinal (stomach, bowel) upset.
PMDD symptoms are related to the menstrual cycle, typically occurring in the second half (luteal phase) of the cycle, and resolving within the first few days after the menstrual period has begun.
