You encounter a 22-year-old man who visited you 4 weeks ago with symptoms of bloody diarrhoea and vomiting. He was diagnosed with Campylobacter jejuni after a stool sample test. He believes that he contracted the infection from consuming undercooked chicken at a barbecue 3 days before the onset of his symptoms.

Although he feels much better now, with the cessation of bloody diarrhoea, vomiting, and fever, he still experiences loose stools 3-4 times a day, along with abdominal pain and bloating after eating food. He maintains a regular diet.

What is the most probable diagnosis from the given options?
