Can I drink fish soup the day after a colonoscopy?

Generally, it is acceptable to drink light fish soup the day after a colonoscopy, but moderation is important. The details are as follows:

A colonoscopy typically involves using a long, flexible medical instrument inserted through the anus into the rectum and then the large intestine, allowing doctors to examine the interior of the colon and detect any intestinal abnormalities. After the procedure, patients may experience mild discomfort such as bloating or abdominal pain. Since fish soup is not a stimulating food, drinking a moderate amount the day after the colonoscopy usually does not irritate the gastrointestinal tract or affect the examination results.

However, when preparing the fish soup, it's best to use minimal oil to avoid increasing the burden on the digestive system, which could lead to symptoms like bloating or abdominal pain. Fish soup is rich in protein; excessive consumption may cause indigestion or an overabundance of a single nutrient. Therefore, intake should be moderate. If biopsy or polyp removal was performed during the colonoscopy, consuming fish soup is not recommended.

After the colonoscopy, patients may start by drinking small amounts of water. If there is no discomfort, they can gradually introduce bland, easily digestible foods such as rice porridge or noodles. By the next day, normal diet can usually resume, but overeating, as well as consuming overly greasy, spicy, or irritating foods, should be avoided. Strenuous exercise and heavy physical labor should also be avoided to allow sufficient time for recovery.
