Weight gain after medication

Weight gain is listed as a possible side effect of many types of pills. I'm curious to know if this effect is always the result of either increasing the appetite or decreasing the activity or is there another mechanism which causes it.

Good question I think its mostly due to the metabolism effect on what it does to the body.

I usually don't eat during the day, just drink cordials or black tea. But when I take my night time meds which includes an added appetite, anti depressant, but also sleepers, seditives, morphine, buprenorphine, then I eat what ever I can while still asleep or very drowsy, it gets so bad that I once woke up with a Stanley blade in my mouth that I thankfully couldn't swallow, I dispise the night, I hate sleeping, too much monkey mind.

Hello 

Different human bodies react differently to the same medicines due to variation in the immune system, medicine tolerance capacity of the body, age, gender and lifestyle. Possibilities are there that one medicine that you have used may result in side effects but when used by some other suffers absolutely no such effects at all. So, it varies! Instead of using chemical-based medicine, why do not you try some natural weight loss supplement that is safe to use? 

Of course. And increased appetite and drowsiness.
