Drug-Induced Weight Gain, Audience Should Know:
• A possible serious side effect of many commonly used drugs used for a variety of disease states
• Leads to exacerbation of co-morbid conditions related to obesity due to associated weight gain
• While some medications are more common than others to cause weight gain, not all individuals gain weight from every drug that has weight gain listed as a side effect
• In many cases if possible, substitute an alternative medication to treat the same condition that is weight neutral or weight negative
