However, for some people, these symptoms are far more severe and disruptive.While both premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD) are related to the menstrual cycle, they are not the same thing \u2014 there are key differences in terms of severity, impact on daily life, and treatment approaches.Learn about the differences between the two and when to speak to a doctor about your symptoms.PMS Meaning vs. PMDD MeaningPremenstrual syndrome (PMS) is a common condition that occurs in the week or two before your period.

While PMS affects 70% to 90% of menstruating people, PMDD affects between 3% to 8% of menstruating people. However, PMDD has more severe emotional symptoms and makes a significant impact on mental and emotional well-being. PMDD symptoms are more intense and can interfere with work, relationships, and overall quality of life.What Are PMS Symptoms?PMS symptoms can be managed without the aid of a doctor, but it is always good to speak with your doctor if you have any concerns.Common PMS symptoms include:Anxiety.Bloating.Breast tenderness.Constipation.Cramps.Diarrhea.Depression.Fatigue.Food cravings or overeating.Headaches.Irritability.Joint or muscle aches.Mood swings.Nausea.Restlessness.Sleep disturbances.Weight gain.What Are PMDD Symptoms?PMDD symptoms are disruptive enough to require the aid of a doctor as they interfere with your everyday life.
