The condition of jailed Rashtriya Janata Dal chief Lalu Prasad is not stable as his both kidneys are not functioning properly and blood sugar and blood pressure are fluctuating a senior doctor attending to him said.

Prasad, 71, is undergoing treatment at the Rajendra Institute of Medical Sciences in Ranchi. He has been in jail since 2017 after his conviction in fodder scam cases.

“His kidneys are not functioning properly. The GFR (glomerular filtration rate) has dropped. His blood sugar and blood pressure are also fluctuating,” Dr. Umesh Prasad, one of the attending doctors, told PTI. “His diet has also decreased compared with earlier. We are giving him medicines now,” he said.
