Has anyone noticed weight gain while using Stelara?

Yes!

In fact, did anyone else initially lose quite a bit of weight with their IBD diagnosis (too much weight loss, unhealthy BMI)? Over the past year with Stelara I have been thankful to be able to eat a more normal diet again and gain 20+ pounds so am back in a more normal range. Anyone else?

OMG. YES!!! Crazy. Was on Humira first. Had antibodies working against it. Started Stelara in May. Supposed to take my next shot today. Not doing it. I have gained 20 pounds and I’ve changed nothing in my lifestyle!! Going to Gastro today. I’m stopping this.

I lost 10 pounds while I was quite sick with IBD, over 1 year. Once on the shot, I gained back 10 pounds in 3 weeks, then continued to gain another 25 extra pounds over next 4 months.

I can only say, I was always 210 - 215 pounds. At 6 feet and muscular. Which was 15 pounds overweight for me. But being 55, I got it. Now I am holding steady at 239 - 241 pounds. Not happy. Still working outside. I need to retire so I can x-ski more, and swim more. I will win this in the end.

I had my infusion and now my second injection. I hadn't noticed a weight problem, but lots of tiredness. After my second injection, I have gained 8 pounds in two weeks. This is unusual for
me.

I started Stelara a month ago and I have gained 10 pounds despite no changes in my eating habits and going to the gym 5 days a week.

I have never been one to gain or loose weight intentionally or otherwise in what some might consider a short period of time. I have been the same 15-20 pounds overweight for many years. Not a problem for me. At the end of the first six months taking Stelara I had gained thirty five pounds over my norm.

YES... The weight gain was slow after the first long dose; however, after getting my first injection I gained 10 in two weeks. I am freaking out. Everyday I get on the scale and I have gained more weight. I do yoga and cycle at least 5x a week. I am careful with what I eat, and I am still gaining weight. I don't think I will take my next dose in November

Sorry, weight gain is not a reported side effect of Stelara.
