You will be able to resume your diet and take your routine medication after you leave the endoscopy area, unless otherwise instructed. Your surgeon will usually inform you of your test results on the day of the procedure, unless biopsy samples were taken. These results take several days to return. The effects of sedation may make you forget what you were told and you should call your surgeon's office for follow-up or instructions, if you were not given any. Gastroscopy and biopsy are generally safe when performed by surgeons who have had special training and are experienced in these endoscopic procedures.
Complications are rare.
Blood transfusions are rarely required. A reaction to the sedatives can occur. Irritation to the vein that medications were given is uncommon, but may cause a tender lump lasting a few weeks. Warm, moist towels will help relieve this discomfort. It is important for you to recognize the early signs of possible complications and to contact your surgeon if you notice symptoms of difficulty swallowing, worsening throat pain, chest pains, severe abdominal pain, fevers, chills or rectal bleeding of more than one-half cup.
