It seems work has been taking its toll of Gauhar Khan. The model-turned-actress, who is seen on the small screen with her sister in UTV Bindass' "The Khan Sisters", has been diagnosed with typhoid.

She has been advised complete bed rest.

"Gauhar has been ignoring her health lately due to her hectic travel schedule as she shuttles from shooting for reality show 'The Khan Sisters" to her stage show Zangoora to her upcoming movie, " said a source close to her.

But the crew of "The Khan Sisters", which records her daily routine, continues to follow her without any break.
