Comorbidities in people with mental illness means they have another disorder in addition to their mental illness. This is quite common. I, for example, have bipolar disorder and chronic migraine.
Comorbidities do not have to be a mental disorder paired with a physical disorder. They can also be two or more mental disorders or two or more physical disorders.
Having more than one disorder has its challenges. For example, a person with both multiple sclerosis and depression would be treated for both conditions, but it would be important to take into consideration the overlap between medications that would be prescribed by different doctors.
For this reason, people with comorbid disorders should take good notes of their symptoms, medications and their side effects, and anything they and their doctors discuss at each appointment so that unwanted interactions are avoided. It is also important to have excellent communication with all providers so that everyone knows what everyone else is doing.
If you have comorbidities, you must be a persistent advocate for yourself to get the proper treatment plan in place to treat all of your disorders so that you can reach and maintain optimal health, both physically and mentally. By following the aforementioned suggestions you can be on your way to better health no matter how many comorbidities you have.
