How do you get your dog to gain weight?

I'm a cancer patience in remission, i wanted to know can i take diet pills to help me with weight gain

I have had Abnormal weight gain Fatigue and many other symptoms, I workout everyday and eat nothing but vegies fish and chicken.

I have been told that wellbutrin can cause weight loss or has no weight gainside effects, but i have been gaining weight. i was doing okay on zoloft i was taking 100mg but dr felt a switch to 100mg wellbutrin...

I didnt start gaining weight until i had sex for the first time...jus found that kinda weird anywho im nt pregnant i knw for a fact can you help me!

I lost 40 lbs last year and i started to the gym last week. Why would I be weighing heavier today? My arms ache and my hands and fingers are tight. I was on the treadmill for 35 min and 2 miles last night....
