Former prime minister Nawaz Sharif is ‘critically unwell’, his doctor said on Tuesday, days after the three-time leader now serving a prison sentence for corruption suffered a minor heart attack. Nawaz Sharif is currently receiving medical treatment at Services Hospital in Lahore. “Former PM #NawazSharif, critically unwell, is fighting the battle for his health & life,” his personal physician, Adnan Khan, tweeted on Tuesday. In addition to the minor heart attack, Sharif has a low platelet count, both of which are being further complicated by ‘deteriorating kidney functions’, Dr Khan said. “Poor blood sugar and blood pressure control is taking its toll … establishing a definitive diagnosis and subsequent management poses considerable risk to #NawazSharif’s fragile and unstable health.” He added. Services Institute of Medical Sciences (SIMS) Principal Dr Mahmood Ayaz, in an informal talk with media, said steroids and injections administered to Nawaz to raise platelet count have created more problems for him as his kidneys are being affected.
