DEAR DOCTOR K: I always assumed my premenstrual mood swings were normal. But then I talked to some friends whose emotional symptoms are much less severe than mine. A quick Internet search turned up "PMDD." Can you tell me more about this?
DEAR READER: The physical symptoms of premenstrual dysmorphic disorder (PMDD) and premenstrual syndrome (PMS) are the same. They include fatigue, swollen breasts, backache, headache, food cravings, bloating, constipation and diarrhea. But the emotional symptoms of PMDD, compared to PMS, are much more severe.
