He has a headache or his eyes hurt.
According to dyslexia.com, dyslexic children struggle with seeing the letters upside down or backwards, such as instead of seeing the word dog, they read god. Dyslexic children often have the tendency to confuse letters that look similar like e and c, or letters that appear similar but are opposites like b and d and q and p. Some children say that the words jump around on the page or that they appear to closely bunched together, both of which makes it difficult for them to read the words. When dyslexic children read a story, they remember very little about what they just read, and these children often complain that reading makes them feel physically ill with headaches, stomach aches, and dizziness.

He fears he’ll have to read out loud and other will laugh at him.
For me dyslexia caused me to distrust my intelligence which in turn resulted in a lack of faith in my opinion. Not having confidence in my judgement left me open to negative people and influences. This meant my self-esteem was constantly being lowered.
My lack of trust in my judgement came from a fear of making mistakes. The only way to trust your judgement is to have faith in your intelligence. (Low Self-esteem: The Importance of maintaining Confidence in Your Judgement)
He will get tested on what he reads and fail.
What many people do not know is that fear of failure blocks the brain in its operation and thus worsens the dyslexia itself considerably. Sometimes it is even so that 50% to 75% of the problems that have dyslexics with language, is caused by the fear of failure. This has to do with their different way of thinking. Once dyslexics are under severe stress or anxiety during an exam, presentation or job interview, when following a new training or having to write a report or assignment, the language in their brain is shut off!
Fear of failure leads to reduced self-confidence and is often the cause of dyslexics in performing worse than they really can and frequently well below their level of intelligence in work or study. (Move Forward With Dyslexia)
He gets lost and can’t remember what he just read.
Learning to read relies on working memory. We have to match each letter with the correct sound, put it together, and remember it for future use.The process of keeping multiple sounds and letters active is often too difficult for most dyslexics because their have poor auditory working memory. This means that they struggle to hold all the sound units in their head, which makes it hard for them to read. (Tracy Packiam Alloway, PhD)
