Can other diseases cause bipolar disorder?

The causes of bipolar disorder aren't fully understood. Scientists currently think that people who develop bipolar have a genetic predisposition that is triggered by some environmental factor or life event. How these factors interact is still unknown. 

Many people with bipolar disorder abuse alcohol or drugs, but the reasons for this link are unclear. People with bipolar disorder may try to treat their symptoms with alcohol or drugs. Experts think substance abuse may also trigger or prolong bipolar symptoms.

Bipolar can occur with other mental health conditions, such as anxiety disorders and attention deficit hyperactivity syndrome. Again, the reasons aren't understood. 

People with bipolar disorder also have a higher risk for thyroid disease, migraine headaches, heart disease, diabetes, obesity and other physical illnesses. Some of these illnesses may cause symptoms of mania or depression, while others may be caused by medications used to treat bipolar.
