I was just posting about this on face book. Many will have toxins excrete out the skin instead of the urine and fail to stop fasting. Then their blood pressure drops and they get nauseated and they think it is normal. What happens is they have organ failure as you stated. He could have been treating a disease not known here and the ultimate cause was the disease. Prolonged dry fasting is not recommended unless under doctor supervision. The way we fast is day on and day off. I will have to look for his messages. I know if you search this forum you will see he was looking for a fasting partner as he planned a long dry fast.
