Drug Classes That Cause Obesity

Though it is mentioned surprisingly little, many over-the-counter and prescription medications cause weight gain. Some of them cause massive weight gain. These 'obesigenic' medications are so common that nearly every American has been exposed to them and many of us take them regularly. It is not my intention here to cause panic and it is certainly not my intention to cause a reader to stop taking a necessary medication. Rather, I simply want to make people aware that there really are a lot of drugs that can make you fat.
