Dr. Shen Yonghua
Gastroscopy is a medical procedure used to examine the inner lining of the stomach. The specific steps are as follows:
1. Preparation before the examination: The patient must fast before the procedure, typically refraining from food and drink for 8 hours prior to the exam.
2. During the examination: The patient will be asked to lie on the examination table. The doctor will slowly insert a long, flexible gastroscope through the mouth into the esophagus and then into the stomach.
3. During the procedure: The patient may experience discomfort or nausea. Local anesthesia or sedatives are usually administered to reduce any discomfort.
4. After the examination: Following the procedure, the patient needs to rest briefly and can resume eating after the effects of the anesthesia have worn off.
If the patient has any specific medical conditions or discomfort prior to the gastroscopy, he or she should inform the doctor for appropriate adjustments.
