Answer: Her diagnosis is Diabetes. Having a high blood sugar constantly creates ketones in the blood stream which leaves your body during urination. Having ketones puts the body in shut down mode. The term for this is DKA. Diabetic ketoacidosis. Diabetic keto acidosis causes all body functions to slowly shut down, due to lack of controlled blood sugar, and insulin. This mostly occurs in someone who has no idea their diabetic or someone who does not take care of their diabetes. Her treatment is to follow a doctors recommendation on how much insulin she needs to be injecting her self with. How many times she needs to check her sugar and ketones in her Urine. And most importantly teach her how to complete these steps every day to guarantee health. She can also get a insulin pump, which is a tiny meter like device that is attached to skin. This is used for patients normally with trouble retrieving blood from their finger tips. The education process of Diabetes includes way more than what I mentioned.
Explanation: I actually know all of this because I am a 19 year old diabetic who had most of the same symptoms.
