4. Increased fatigued
Fatigue is a symptom that is commonly associated with several medication conditions. However, if you feel as if you have no energy and like all you want to do is sleep, no matter how much sleep you are getting, and you are also experiencing an increased need to pass urine and are excessively thirsty, then there is a very good chance that you have developed diabetes insipidus.
Your body relies on water for all of its metabolic functions. When water levels are off, you will experience extreme fatigue, as your body is not receiving the hydration that it needs.
