Bipolar Disorder Meds Increase Risk of Metabolic Syndrome and Type 2 Diabetes
Bipolar Disorder Meds Increase Risk of Metabolic Syndrome and Type 2 Diabetes

Metabolic syndrome is a collection of conditions, including insulin resistance, that can often lead to a diagnosis of type 2 diabetes if it is not reversed with diet and exercise. But sometimes factors beyond our control may cause metabolic syndrome.

Bipolar disorder is a medical condition with symptoms that include extremes of mood known as depression and mania. Many of the medications prescribed for bipolar disorder can place people at risk for developing metabolic syndrome.

According to the online journal, Bipolar Disorders:

"The prevalence of the metabolic syndrome in patients with bipolar disorder is alarmingly high, as it is for the general population. The prevalence of obesity is even higher than the already very high prevalence that has been estimated for the US general population."
Many of the medications used to manage bipolar disorder are thought to contribute to the risk of developing metabolic syndrome and type 2 diabetes. Not all medications used for bipolar disorder cause metabolic symptoms but the medications listed here are more prone to causing weight gain, insulin resistance, hyperglycemia (high blood glucose levels) and other signs associated with metabolic syndrome.

Olanzapine (Zyprexa) - weight gain, hyperglycemia
Sodium valproate and valproic acid (Depakote) - weight gain
Clozapine (clozaril) - weight gain, hyperglycemia
Quetiapine (Seroquel) - weight gain, hyperglycemia
Risperidone (Risperdal) - weight gain, hyperglycemia
Lithium - transient hyperglycemia
Many physicians have become aware of the implications of bipolar disorder and the accompanying medications on the development of metabolic syndrome and diabetes. According to the online journal, Psychiatric Times, of January 2007:

"Considering the emerging recognition of the true enormity of the metabolic consequences of bipolar disorder, drugs with an advantageous metabolic profile should be considered as first-line therapy in the long-term management of this condition."
In other words, medications that don't cause the symptoms of metabolic syndrome should be prescribed first. Only if those drugs are ineffective in treating bipolar disorder, then should the drugs that are likely to cause metabolic syndrome be prescribed. Also if patients are on those drugs, they should be monitored for weight gain, high cholesterol and insulin resistance and glucose intolerance
