Someone more knowledgeable than myself please explain. Thanks!
I'm not familiar with the medications listed above, but I do know that many antidepressants and antipsychotics are associated with weight gain. The exact mechanism is uncertain, though there is some supposition that they trigger cravings for carbs. They may also make you hungrier (like steroids, so you eat more...although steroids also have some effect on glucose and can increase fat stores, I believe). Also, with the antidepressants, lack of appetite is a frequent symptom of depression, so when the meds kick in and one is less depressed, eating increases. It's also been speculated that the meds affect metabolism in a negative way. Additionally, some of these medicines can cause fatigue, making a higher level of activity more likely. So, in reality, the medications make it more likely to do what results in weight gain...take in more calories than you expend.
Good luck, Lori; I hope you get it figured out. You're in the right place, with all the tools and support here
