Walt Breidigan starts out with flu-like symptoms, but soon becomes dizzy from hypotension. He develops pain in his legs and even gains a hundred pounds in just one day. At first, Walt thinks he is all better after taking diuretics to drain excess fluid in his body, but two years later, his symptoms return. Finally, he finds out that he has a rare capillary disorder called systemic capillary leak syndrome. Young Ashley has been a healthy little girl until shortly after her fourth birthday, when she becomes constantly thirsty. Along with the incessant thirst, she also has to deal with constant trips to the bathroom, double vision, and headaches. It turns out that Ashley has a tumor in her brain called a pineal germinoma.
