I've been working on a dozen case studies for my Anatomy class and there's only one giving me problems. I just don't think there's enough symptoms to go on, but here it is: A young athlete is admitted to the hospital with diarrhea, vomiting, bone and joint pain, hyperglycemia, and tingling sensations. What is the problem? Is it a case of untreated diabetes, maybe Diabetic ketacidosis?
