What to Eat After an Upper Endoscopy- Foods to Eat and Avoid

Upper Endoscopy, also known as Gastroscopy, is a medical examination procedure through which a doctor or a Gastroenterologist examines the upper intestinal region of the body, including the duodenum and the esophagus, through an endoscope. As you might be aware, an endoscope is a thin tube with a light and camera attached to it and which is inserted through the mouth for examination purposes. Over the last 15 years, video capsules are used for GI examinations and they do not require insertion of the endoscope. The patient intakes the capsule (that is designed with a small video camera), which is naturally excreted later.

Upper endoscopy is useful for evaluating many different kinds of symptoms. It can easily find out the causes of nausea, vomiting, difficulty in swallowing, and heartburn among other symptoms and may also help in the diagnosis of cancerous lesions, ulcers, and other medical problems.

After the upper endoscopy

As Gastrointestinal Endoscopy (using the tube) is performed under anesthesia, you might feel groggy at the end of the procedure. While some patients who undergo endoscopy might feel a very slight discomfort, others often fall asleep as a sedative is used during the procedure. Patients may feel bloating post procedure and may be monitored for 2 hours, because of the use of a procedure sedative.

What to eat after Gastroscopy or Upper Endoscopy

If the throat has been sprayed with anesthesia during the gastroscopy process, you should not eat anything for at least 1-hour post endoscopy. Once the time period is over and if the doctor has not provided you any special eating or drinking guidelines and instructions, you can:

  • Start to sip clean drinking water, and other kinds of cool liquids.
  • Fresh juice of fruits makes a good choice as well.
  • Other than the soups, you can also try the light and soft food items including eggs and pudding.
  • Avoid eating any kind of heavy meals for 24 to 48 hours.

In case the throat was not sprayed with anesthesia during endoscopy, you can start to eat the light and soft foods immediately after the endoscopy procedure is completed.

Side effects

You may have a sore throat feeling once the endoscopy is completed. It can be overcome by using salt water or saline gargle or (OTC) over-the-counter cough drops available at pharmacies or in the local general stores. A sore throat may for up to 48 hours and will subside naturally.
