💧 German architect Marc Wübbenhorst has to drink at least 20 liters of water a day or risk dying from dehydration. The 35-year-old suffers from the rare metabolic disease Diabetes insipidus, which causes intense thirst and the frequent excretion of large amounts of diluted urine. If Wübbenhorst stops drinking water, his body starts to dry out, and he can die of thirst in a matter of hours.⁠
⁠
Constant thirst has been a part of Marc Wübbenhorst’s life for as long as he can remember. It’s nothing like the thirst a normal person experiences because it doesn’t go away after drinking a glass or two of water. His body can’t hold any water, as his kidneys eliminate the fluids almost as fast as he ingests them. Marc can never ignore his thirst for more than an hour, because he starts to experience severe symptoms of dehydration, like cracked lips, dizziness, and confusion. These are symptoms that most adults experience after two or three days of fluid deprivation.⁠

🧬 Although Diabetes insipidus can develop at any point in life, Wübbenhorst was born with the condition. As a child, he managed his condition relatively well, he had lots of friends and tried to live a normal life, but at one point it got too much, and he fell into a deep depression.⁠
“I had a kind of exhaustion depression,” Marc told Neue Westfälische. “I did not want to go to kindergarten, paint anymore, or see the lantern parade.”⁠
⁠
Each day in Marc Wübbenhorst’s life begins with a big bottle of water to fill him up, but it doesn’t last long, as he soon has to go to the bathroom. It’s even harder at night, and the 35-year-old admits that he has never slept for more than two hours at a time in his whole life. He constantly has to get up, hydrate, and then go to the bathroom to excrete all the fluids. In total, he visits the toilet up to 50 times in 24 hours.⁠
