Pain and Discomfort: Abdominal surgeries, in particular, can result in pain and discomfort, making eating uncomfortable and distressing for the patient.

Swelling and Inflammation: Surgeries can lead to swelling and inflammation in the affected areas. This swelling might impair the functioning of the digestive tract and make eating solid foods difficult.

Bowel Rest: Following certain surgical procedure (especially those involving the digestive system), doctors may recommend a period of "nowel rest" during which the intestines are allowed to heal and recover. During this time, clear liquid and a gradual transition to soft foods are introduce to minimize any additional irritation to the digestive system.
