Contestant Lakshman Ahirwar is reported to have committed suicide after the actress-turned-television host called him "impotent", reports India Today.
Psychologist Sameer Vohra claimed that Sawant was not trained to present this type of show, adding: "Whatever is being said is being watched by millions, and that itself can be perceived by a participant in a very negative way.
"Someone who is just a celebrity and not qualified to handle counselling should not be allowed to handle such complicated real-life issues."
The Main Hoon Na actress has received widespread criticism following the screening of the episode, although the programme producers have denied that the participant killed himself.
"From what we have gathered, Lakshman came back home quite drunk and fell sick shortly afterwards. He was admitted to hospital and passed away soon after," said a spokesperson for Imagine TV.
