About NDI – "I could drink all the water in the world, and still feel thirsty"
A normal person couldn’t survive 3-5 days without water, but for some this severe dehydration happens in hours. What if your body could not use the water you drank and every drop you took in just came right out? What if your urine has never darkened to tell you that your body is becoming dehydrated?
This condition is called Diabetes Insipidus.
“ Depending on how many fluids are consumed over the course of the day, a person with diabetes insipidus may expel over 20 liters of urine over the course of 24 hours.
