Scary weight loss help

Hello everyone!

So I have been steadily loosing weight for 3 months now. Had a big flare in may and lost 15 in 1 1/2 weeks, went from 125 to 110. I am a 19 year old female and I am 5'5. I was out on steroids and dropped a few more pounds. Well everything was getting better, my weight was holding steady and I was feeling like a whole new person! I still could not gain any weight though. My GI had me on a 2 month course of Uceris, and then added one more month to make it 3. A the 9 week mark I had a few very very stressful situations, and I started to flare again. My GI had me start Lialda a couple days later. Well, now it's a little over a week since this flare started and I weigh 99lbs. I am very scared, I have never lost this much weight. The flarenis starting to subside, I'm not going to the bathroom that much but for some reason I'm still loosing weight. I eat plenty of food and I have been able to keep it in, so I really don't understand why I'm still loosing weight! Anyone have any tips to gain weight or at least not lose anymore? Any explanation why I'm losing weight? Anyone else experience this? Thank you!

Weight loss can be from a lot of things: not ingesting enough calories, not absorbing enough of what you eat due to small bowel inflammation, or just the extra strain the disease puts on your body, which makes you burn more calories than you otherwise would.

Do you have small bowel disease or just in the colon?

Lialda is not an appropriate medication. It's a UC drug that was never approved for Crohn's disease. Doctors often prescribe it due to wishful thinking ("if it helps UC, and UC and Crohn's are similar, then it will help Crohn's too.") But studies have shown it does NOT help Crohn's.

Have you done any stool tests to see if there is fat or protein in the stool that wasn't digested properly? Do you have any signs of fat or protein malabsorption?

Have you had any recent looks at your small bowel, like an MRI?

This type of weight loss can and does happen sometimes with Crohn's. Often times, stronger, more appropriate medication (like Remicade or similar) can really reverse the unwanted weight loss. Lialda isn't going to cut it at all. Uceris can help with mild to moderate inflammation in the colon, but since digestion primarily occurs in the small bowel - where Uceris doesn't affect - you may need some other treatment if that's your issue.
