Abdominal pain, blood in stools,

Severe abdominal pain, blood in stools. I've been taking the treatment for the same from past 1.5 yrs, I'm on mesacol od tab. I got admitted twice last year and for the third time in march 2021. I had very frequent visits to the hospital. But the same hasn't been reducing. Iam vomiting everytime I eat, I lost 13kgs of weight recently as well. pain isn't reducing so is the bleeding.

And had my endoscopy done 4-5 times which had gastritis grade c .
