Many of the symptoms of PMDD are the same as those of PMS, such as weight gain or bloating, breast swelling or tenderness, lack of energy, and changes in appetite or eating habits. But if these symptoms are present along with irritability, depression, anxiety, or affective lability (or sudden shifts in mood), then you may have had PMDD. You may also experience a loss of interest in activities you once enjoyed, difficulty sleeping, or inability to concentrate. All these symptoms must also interfere with your daily functioning such as at work or socially.
