I started Stelara (Ustekinumab) about a year ago because I had a flare up. I've been noticing that I continue to gain weight even though I exercise 5 times a week. I also eat really healthy. I'm not at a place where I need to gain weight or have recently lost weight. I'm actually working on losing a few pounds that I gained while being very sedentary during my flare up. I've reached a healthy weight but it just continues to climb for no apparent reason.. Has anyone else experienced weight gain with Stelara?
