Safdarjung Hospital said Sonam Wangchuk was admitted after a 20-day fast, with tests showing dehydration, low potassium levels and metabolic changes associated with prolonged fasting.
The hospital stated that Wangchuk has refused intravenous fluids, oral rehydration solution and medication, and is being continuously monitored and counselled by a multidisciplinary medical team.
The medical report was released after Wangchuk's wife alleged that his potassium levels were not shared in writing, while the hospital maintained that the information had been included in the patient summary provided to the family.
