Son is 17 and recently began having toilet problems

For the last 3 weeks our son has been holding onto his poo. He was toilet trained around 4 years old but now refuses to let his no2's go it go as he thinks he might die. He says this started when he struggled to go one day. We've explained the danger if this but he says "you're lying". We are getting desperate to stop this behaviour. Anyone faced this before,

  • What does he eat in a typical day, if that isn't too nosy a question?

    I ask because diet is one of my special interests. Some foods affect people in different ways so it's possible there are one or two foods he's eating that are causing constipation. Another possibility is something he's eating is making having a poo painful or uncomfortable as it could be something that doesn't agree with his digestive system.
