PMS vs. PMDD: What's the Difference?

PMS vs. PMDD: What’s the Difference?

PMS and PMDD have similarities, but we’ll go over how they are different. You may dread that time of the month due to the symptoms that occur right before menstruation. PMS and PMDD are groups of symptoms that occur a week or two before your period; however, PMDD is much more severe.

PMS stands for premenstrual syndrome and it refers to both physical and emotional symptoms due to a shift in hormones right before your period. Common symptoms include acne, tender breasts, irritability, mood swings, cramping, bloating, and lack of energy.

PMDD stands for premenstrual dysphoric disorder and it causes severe irritability, depression, or anxiety. It is essentially a severe form of PMS. The causes of PMS and PMDD are unknown, but they may be due to changes in mood chemical levels that occur throughout the menstrual cycle, like serotonin and GABA, due to hormonal fluctuations in the luteal phase. Serotonin is often known as the happy mood chemical, since it contributes to the feeling of wellbeing, therefore, decreased serotonin contributes to symptoms commonly associated with PMS and PMDD.
