Height growth failure

I've been diagnosed with crohn when i was 13 yo and i stopped growing for months 😔. My brother which is 1 year younger surpassed me in height at that time and ever since.

I am currently 180 cm at 18 yo and my brother is 188cm at 17 yo which is a big difference. I feel like i was destined to be taller like my brother but now because of that stupid ahh disease i am small 😭.

Did you guys reached a final height below expected (or taller than expected) or do you know someone with crohn smaller than their siblings ? Did you have growth retardation and when did you stop growing ?
