Why do certain medications increase you appetite and increase weight gain?

Question

I was on a few medications last year and gained a significant amount of weight even though I didn’t necessarily feel more hungry. What causes this?

Side note: if someone could explain why I get the munchies after smoking weed as well, that would be great.

Answer 1

For THC, it triggers the same areas of your body that get triggered when you’re hungry. So, your body thinks it’s hungry without the usual trigger, so you are willing to eat more despite not actually needing food.

This might work slightly differently per medication, but it’s the same principle for most of them.
