"Sushma Swaraj's condition is constantly improving and there is nothing to worry. She will be released soon but we can't say exactly when," said Amit Gupta, spokesperson of the All India Institute of Medical Sciences.
Asked if Sushma Swaraj had developed any problems during treatment, Mr Gupta said: "Nothing major. She is already a cardiac patient, so there is fluctuation in her health condition. But she is stable now."
Sushma Swaraj was admitted to the AIIMS last week over problems of chest congestion, fever and arthritis.
Prime Minister Narendra Modi, Congress vice president Rahul Gandhi and Madhya Pradesh Chief Minister Shivraj Singh Chouhan visited her to enquire about her health.
