The broadcasting watchdog confirmed that most of the complaints were regarding the former health secretary's mere presence on the reality show.
Ofcom will assess the complaints against its broadcasting rules before deciding whether to investigate.
According to Ofcom data, around 1,100 people complained about Hancock starring on the show while there were also complaints about how he was treated by other contestants.
The nearly 2,000 complaints were made between 8 and 14 November.
Ofcom said in a statement: “It’s worth being aware that under our rules, in principle – and taking into account freedom of expression – there’s no ban on any particular person taking part in programmes.

"However, if the mere presence of a person is likely to cause offence, we would expect broadcasters to take steps to mitigate or justify that offence. How they do that editorially is up to them.”
Hancock's decision to appear in the jungle had been met with criticism from both the public and his fellow MP's with him being suspended from the Conservative Party.
ITV has defended its decision to put Hancock in the jungle with the show's executive producer Olly Nash saying: “We’ve put in loads of politicians over the years, we also put in people who have had very strong views about certain things, and sometimes it plays out in camp and sometimes it doesn’t."
He added: “It’s not a question of trying to divide camp, we have never been a deliberately divisive camp. It’s up to them to come into the camp and it’s up to them if they want to leave.”
During his time in the jungle, Hancock has faced several bushtucker trials and been elected camp leader.
