Narmada Bachao Andolan leader Medha Patkar's health deteriorated on Tuesday, the fifth day of her indefinite fast demanding the rehabilitation of people affected by Sardar Sarovar Project before monsoon.

Patkar vomited, but refused any medical check-up when a government doctor's team met her at the agitation site in front of the Divisional Commissioner's office at Nasik Road, NBA spokesperson Pratibha Shinde said.

The NBA has received a message from former Progressive Democratic Front Minister Bhai Vaidya that Chief Minister Sushilkumar Shinde has invited him and social activist Mrinal Gore to discuss the issue. Nationalist Congress Party leader Vasantrao Pawar was also expected to discuss the matter with Patkar.

Meanwhile, the indefinite 'dharna' (strike) by the NBA activists entered the ninth day on Tuesday. City Police Commissioner Prakash Pawar and his senior colleagues met Patkar on Monday night and urged her to undergo a medical check, which Patkar refused.

Oustees, including those of the Sardar Sarovar Project, have threatened to join the indefinite protest if the meeting convened by the Irrigation Ministry of Maharashtra for discussing the issues pertaining to their displacement and resettlement was not held as per schedule by June five.

Many organisations, including the Naisk city scrap material association have expressed their support to Patkar on the issue.
