In my book series, there is a small planet called Eaglypt. On this planet, there is a huge famine because an evil space overlord named Tate magically summoned a sandstorm that choked up the oasis (and thus the rivers fed by it) that Eaglypt uses to irrigate its crops in the harsh global desert. Anyway, the entire population eventually starves and dies. However, the royal family possesses a one-man escape pod (the only spaceship on Eaglypt that Tate didn't have his army destroy). Using this escape pod, Taftenkhamun (the heir to the Eaglyptian throne) escapes to live a life on a faraway planet as the last of his kind. However, Taftenkhamun was absolutely starving by the time he arrived (due to both Eaglypt's famine and the fact that his pod had no food on it).
What side effects would Taftenkhamun be likely to suffer from for the rest of his life as a result of being starved to near-death?
