Bollywood actors often work on tight schedules and have irregular work hours. This results into major health problems for most of them. Recently, actress Vidya Balan had to be hospitalised while she was busy shooting for her ambitious project ‘The Dirty Picture’. A source said, “Vidya has been taking her role in ‘The Dirty Picture’ very seriously. With constant shoots and the stress it obviously entails, Vidya started feeling rather dizzy and restless about ten days back. Her parents took her to the doctor who advised immediate hospitalisation.” Vidya was admitted and kept under observation for three days. The actress underwent several tests and the results indicated that her hemoglobin level was too low. Vidya was immediately put on drip. “Even though she has been discharged, the doctors have given Vidya strict instructions to rest for the next week,” added the source. Due to Vidya’s health condition, the filming of ‘TDP’ has been put on hold for a while.
