Bipolar disorder is a mental health condition that causes extreme mood swings that include highs (mania or hypomania)- may feel euphoric, full of energy, need less sleep and unusually irritable; and lows (depression)- may feel sad or hopeless and lose interest or pleasure in most activities. Episodes of mood swings may occur rarely or multiple times a year. While most people will experience some emotional symptoms between episodes, some may not experience any. Although bipolar disorder is a lifelong condition, it can be managed by a holistic treatment plan.
