According to Radar Online, the reality TV star was rushed to a Miami hospital and treated for suspected alcohol poisoning.
"She was so drunk that she had to be carried out of the nightclub Dream by the show's producers," a source said.
However, the programme's bosses apparently decided to cut the alleged incident from last Thursday's episode.
The insider added: "Snooki was out of commission for about two days and was left in pain after undergoing the hospital treatment."
MTV and Polizzi have yet to comment about the reported hospital stay.
Polizzi was fined $500 (£315) and ordered to serve community service earlier this month for drunk and disorderly conduct on a beach.
