Diabetes is a condition that requires you check yourself 24/7 - for the rest of your life. You need to log every gram of carbs you eat and supply your body the insulin it needs, usually with needles. Diabetics have to wake up 2-4 times a night to balance their blood sugar, or otherwise risk to die in their sleep. What it´s really like to have T1 diabetes is beautifully explained by one of the inventors of the Artificial Pancreas, Dana Lewis. The invention of "closed or hybrid loop systems" is one of the most profound revolutions for diabetics in the 21st century.
