After a month-long electioneering and review of performance of various departments after the polls, Karnataka chief minister BS Yeddyurappa is undergoing body rejuvenation treatment at a Naturopathy Institute, on the city outskirts here.

Yeddyurappa (66), who had been planning for a few days rest and treatment got admitted into the Jindal Naturopathy institute on Sunday, according to his media advisor, RP Jagadeesha.

"The chief minister will be under treatment till May 14 according to tentative programme," he said.

Yeddyurappa, heading the first ever saffron party government in Karnataka, criss crossed all the 28 Lok Sabha constituencies to campaign for the party nominees.

Soon after the second phase of polling ended on April 30, Yeddyurappa sought the EC permission to hold official review meetings.

During last week, he reviewed the working and progress of works in several departments and also chaired a cabinet meeting.
