Speaking about ''Yeh Rishta Kya Kehlata Hai's'' success producer Rajan Shahi said, "Yeh Rishta Kya Kehlata Hai doing well is something we have to strive for each and every day. When a show completes this number of episodes, it becomes a challenge as to how to sustain the show. There are so many topics to choose from and there are so many relationships, so that becomes a major challenge, to keep the freshness alive. Drama, intrigue, etc is just a part of storytelling but to still keep the essence alive that is the challenge, it is always a day to day battle". He also quoted that the elaborate festival celebrations shown is the strength of the series. Speaking about the introduction of transition in the story from Akshara and Naitik to Naira and Kartik, Shahi said, "We were losing out on the young audience when things were going sweet between (original protagonists) Akshara and Naitik. With the introduction of Kartik and Naira -- a couple that is imperfect, makes mistake and learns from the mistakes -- the audience again found a connection with the on-screen characters. That is how our show has stood strong against the test of time". In May 2017 Shahi stated: For his above statement both Khan and Mehra expressed their displeasure where Khan stated: Mehra stated: In May 2022, actress
Pranali Rathod worn a bridal lehenga worth ₹2.5 Lacs approximately for Akshara and Abhimanyu's wedding sequence, the costliest lehenga ever worn by any YRKKH actress. In March 2024, after the termination of

Casting Hina Khan was cast to play Akshara Singhania, making her acting debut. Khan stated that she knew nothing about acting while signing the series quoting, "I didn't learn acting from anywhere. I think it's because of luck that I landed up in TV. Even after that I had to do a lot of hard work. It was more difficult for me when I began acting and straight away I had to perform. I never got to learn".
Karan Tacker was initially roped for the role of Naitik, but was replaced by
Karan Mehra a day before the promo shoot as Tacker became skeptical. Speaking about it producer Rajan Shahi said, "Karan refused to be a part of the show a day and a half prior to shooting the promo. I needed to hunt for a new face on immediate basis. I accidentally met Karan Mehra, a real life replica of my fictitious character Naitik". In June 2016, Mehra quit the show, because of health issues.
