Is it ok to eat chocolate after tonsillectomy?

No, it is not recommended.

Eating chocolate, along with other types of sweets, can put you at risk of infection as the bacteria causing it thrives on sugar. Additionally, chocolate may cause irritation and inflammation which could impede the healing process. Also, chocolate contains caffeine that may prevent blood clots from forming and prolong the bleeding.

During the early days of recovery, a soft, bland diet is usually advised by doctors to avoid disrupting the healing process.
