It is best to eat a light meal and drink extra liquids following a colonoscopy, according to Colon & Rectal Surgery Associates. In general, it is safe to eat immediately after your procedure.
While it is likely that you are hungry as a result of the highly restrictive pre-colonoscopy diet that is required, a light meal is recommended after the procedure as opposed to foods that are greasy or spicy. This helps to avoid nausea and vomiting that may be caused by the sedation drugs, according to Colon & Rectal Surgery Associates. Alcohol should not be consumed for at least 24 hours after being sedated. Because of the water lost during the procedure, the patient may be asked to drink extra fluids.
During a colonoscopy, it is likely that air will build up in your intestines, which may cause bloating, gas and mild cramping after the procedure, states the American Gastroenterological Association. This, in turn, may affect appetite. These symptoms should disappear within 24 hours, and a normal diet can be resumed.
In the event that the doctor has noticed anything unusual or removed small growths, called polyps, from the digestive tract during the procedure, a clear liquid diet may be recommended for a few additional days until further testing is completed, reports SFGate. The doctor may also request the patient to fast for a few hours and avoid foods that are high in fiber for 24 hours.
