Israeli agent Jonathan Pollard was hospitalized on Wednesday after a deterioration of his medical condition, and underwent surgery that was apparently related to his intestines, sources close to him said Thursday night.Pollard, 59 had been suffering from various medical ailments and extreme pain for an extended period. His health has deteriorated over the nearly 28-and-a-half years he has been in prison.“He had surgery to fix multiple serious complications in his digestive system,” Esther Pollard said of her husband. “His condition is worrisome. He is worn out. I’ll only know more details when he is well enough to tell me.”The long list of ailments from which he has suffered over the years includes diabetes, nausea, dizziness, blackouts, and ongoing issues with his gall bladder, kidneys, sinuses, eyes and feet.He also suffers from Meniere’s disease, which causes him to lose consciousness and fall without warning.A rally took place outside the US Embassy in Tel Aviv Thursday night asking for US President Barack Obama to commute Pollard’s life sentence to time served. Pollard’s wife prayed for his health and freedom Thursday at the Western Wall.
