Delhi Chief Minister Arvind Kejriwal has been advised not to exert himself and remain silent for a while after he underwent a 5-hour throat surgery in Bengaluru on Tuesday.

Kejriwal underwent the surgery for chronic cough at the Narayana Health City in Bommasandra, Bengaluru. Doctors said that the Delhi CM's tongue was too big for his mouth. they stated that Kejriwal suffered from an "enlarged soft palate and uvula in relation to a slight increase in the volume of the tongue".

"He was operated on Tuesday for persistent cough which has troubled him for over 40 years. The surgery corrected an anatomical abnormality of his oral-pharyngeal (part of the throat) and palatal (top surface of the mouth) that was causing small amounts of saliva to trickle into his air passage whenever his nose-breathing was affected by allergy or other factors," the hospital said in a press release.

Dr Paul C Salins, medical director and vice-president at Mazumdar Shaw Medical Centre, made the initial diagnosis of Kejriwal's throat condition and later operated him too.

"There was a restricted space for the movement of his tongue and an enlarged soft palate and uvula in relation to a slight increase in the volume of the tongue that caused kinematic problems in the function. The surgery involved correction of a significant septal spur and palato-pharyngeal (small muscle at the roof of the mouth) correction. There was repositioning of the tongue-base relationship along with the reorganisation of the chin area. The aim of the correction was functional restoration rather than that of a disease," the release stated.

The doctors said that Kejriwal's recovery will be gradual and he has been advised not to talk for a couple of days.
