Physician Yaroslav Ashikhmin said Saturday that test results he received from Navalny''s family show him with sharply elevated levels of potassium, which can bring on cardiac arrest, and heightened creatinine levels that indicate impaired kidneys.
“Our patient could die at any moment,” he said in a Facebook post.
Anastasia Vasilyeva, head of the Navalny-backed Alliance of Doctors union, said on Twitter that “action must be taken immediately.”Navalny is Russian President Vladimir Putin''s most visible and adamant opponent.
His personal physicians have not been allowed to see him in prison. He went on hunger strike to protest the refusal to let them visit when he began experiencing severe back pain and a loss of feeling in his legs. Russia''s state penitentiary service has said that Navalny is receiving all the medical help he needs.
Navalny was arrested on Jan. 17 when he returned to Russia from Germany, where had spent five months recovering from Soviet nerve-agent poisoning that he blames on the Kremlin. Russian officials have denied any involvement and even questioned whether Navalny was poisoned, which was confirmed by several European laboratories.
He was ordered to serve 2 1/2 years in prison on the grounds that his long recovery in Germany violated a suspended sentence he had been given for a fraud conviction in a case that Navalny says was politically motivated.
