Question
I'm an eighteen-year-old girl who is about 5'4" tall and weighs close to 110 pounds. I'm interested in water fasting, and have already completed a few two to three day water fasts in the past. Now I'd like to embark on a longer one. How long can I fast on water unsupervised without experiencing consequences that would require medical attention?

Answer
It is not suggested to fast unsupervised as a rule ever. I would never go more than 3 days with only water. Blood sugar and many other health issues need to be considered. Always let someone know you are doing this. I full check-up is suggested before any type of fast. Blood sugar levels should always be checked and heat issues should be considered as many parts of the country are very hot right now. Also electrolytes can easily become unbalanced in the heat which can promote fainting, low blood sugar and pressure and dizzyness.
