It’s definitely important to treat bipolar disorder, as if it’s left untreated, it can lead to other serious problems that can affect every area and aspect of your life. These other problems can be: - Relationship problems - Poor performance at work or school - Financial problems or even legal problems - Drug/alcohol misuse or abuse - Suicidal thoughts or attempts (Please, if you feel suicidal or you know someone who you believe could be suicidal, call 911 or the National Suicide Prevention Lifeline at 1-800-SUICIDE) Also, it’s possible to have another health condition that co-occurs with bipolar disorder and makes it worse. If this other condition is left untreated too, there could be further complications. A co-occurring condition may be: - An anxiety disorder - An eating disorder - Alcohol/drug abuse - ADHD (attention-deficit/hyperactivity disorder) - Physical health conditions like a thyroid problem
