Feeling nauseous after having a gastroscopy

In general, feeling nauseous after undergoing a gastroscopy may be caused by factors such as anesthesia stimulation, neurological reactions, or gastritis. A detailed analysis is as follows:

1. Effects of Anesthetic Medication

During gastroscopy, anesthetic medications are commonly used to reduce discomfort and help the patient relax. Certain anesthetics may trigger nausea and a sensation of vomiting. This condition usually resolves on its own once the effects of the medication wear off. Symptoms typically improve with appropriate rest.

2. Neurological Reaction

Gastroscopy may cause tension and anxiety, leading to a neurological response such as nausea and vomiting. It is recommended to inform the doctor about any concerns or discomfort prior to the procedure. The physician may administer sedatives or other soothing measures to help the patient relax and reduce anxiety.

3. Gastritis

If a patient already has gastritis, this may also lead to feelings of nausea and vomiting following gastroscopy. Under medical guidance, patients can take medications such as bismuth potassium citrate tablets or colloidal pectin bismuth capsules for treatment.

Besides the above common causes, nausea and vomiting after gastroscopy could also result from conditions such as gastric ulcers, gastroesophageal reflux, or enteritis. It is advisable to seek timely medical evaluation at a hospital to determine the underlying cause and receive targeted treatment accordingly.
