Reasons for Undergoing Upper Endoscopy: Symptoms and Indications


Upper endoscopy, which is also known as esophagogastroduodenoscopy (EGD), is a medical treatment that is used to check the upper gastrointestinal tract. This examination includes the esophagus, the stomach, and the first part of the small intestine (the duodenum). Investigation of a wide range of symptoms and illnesses that are associated with the upper digestive tract requires the utilization of this flexible diagnostic instrument. In this extensive guide, we will discuss the reasons for having an upper endoscopy performed, with a particular emphasis on the signs and symptoms that may lead to the need for this surgery.

Acquiring Knowledge of Upper Endoscopy (EGD)

First things first: before we get into the specifics of why an upper endoscopy is necessary, let’s make sure we have a good grasp on what the process entails.

Endoscopy of the upper gastrointestinal tract, often known as EGD, is conducted with the assistance of a long, flexible tube called an endoscope. This particular endoscope features both a camera and a light source, which enables the medical professional to obtain a real-time image of the upper digestive tract while using the device. The process can assist in the diagnosis of a wide variety of diseases and ailments, ranging from simple digestive issues to more complex diseases.

The endoscope is placed through the mouth during the EGD process, and then it is guided down the patient’s throat and into the esophagus, stomach, and duodenum. The images that are acquired by the camera are presented on a monitor, providing the physician with the ability to study the lining of the upper gastrointestinal system, obtain samples, and even perform specific treatments or interventions.

Upper Endoscopy: Symptoms and Indications for the Procedure

The upper endoscope is a helpful instrument for the diagnosis and management of a wide variety of illnesses and symptoms related to the upper gastrointestinal tract. Let’s take a look at some of the most typical signs and symptoms that can point to the need for an upper endoscopy:

Gastroesophageal Reflux Disease (GERD), also referred to simply as Chronic Heartburn: Heartburn, regurgitation, chest pain, and difficulty when swallowing are some of the symptoms that may be experienced.

Indication: An esophagogastroduodenoscopy (EGD) might be helpful in determining the amount of esophageal damage and identifying potential problems such as Barrett’s esophagus or strictures if symptoms are persistent and medicine does not alleviate the condition.

The difficulty swallowing is referred to as dysphagia. Symptoms include pain or difficulty during swallowing, as well as the feeling that food is becoming lodged in the chest or the throat.

An evaluation of the reason of dysphagia, which may be brought on by esophageal narrowing, inflammation, or the presence of an obstruction, can be carried out with the use of an upper endoscopy.

Nausea and Vomiting on a Regular Basis:

Symptoms include nausea and vomiting that cannot be explained, as well as chronic discomfort in the abdomen region.

  • Indication: An EGD can be helpful in identifying the underlying reason of chronic vomiting or nausea, which may include gastritis, ulcers, or other gastrointestinal disorders. This can be done by determining whether or not the patient has had an EGD before: Pain in the Upper Abdomen That Cannot Be Explained:
  • Pain in the upper abdomen that is inexplicable and continues to persist as a symptom. Upper endoscopy is indicated because it has the potential to detect the presence of ulcers, gastritis, or other disorders that could be the source of the pain.

Bleeding from the Gastrointestinal Tract

Symptoms include vomiting blood, having feces that are dark or tarry, or developing anemia for no apparent reason.
Indication: an endogastric duodenoscopy (EGD) is an essential tool for determining the cause of bleeding in the gastrointestinal tract, which may be due to ulcers, varices, or other diseases.
Celiac disease with Symptoms That Are Hard to Diagnose:

In spite of following a gluten-free diet, symptoms include persistent diarrhea, abdominal pain, bloating, and weight loss. Upper endoscopy, in conjunction with a biopsy, is an essential part of the diagnostic process for celiac disease and is used to evaluate the degree of intestinal damage.

Monitoring Patients with Barrett’s Esophagus

Patients who have a history of chronic GERD and are at risk for developing esophageal cancer have the symptoms listed above.

  • Indication: It is advised that regular EGD surveillance be performed in order to monitor the progression of Barrett’s esophagus, a condition that can lead to cancer, and to detect early signs of dysplasia or malignancy.
    Eosinophilic Esophagitis, also referred to as EoE:
  • Symptoms include trouble swallowing, food getting stuck in the throat or esophagus, chest pain, and acid reflux, especially in younger people.
    EGD with a biopsy is indicated for the diagnosis of EoE as well as the evaluation of the extent of esophageal inflammation.

Evaluation of Polyps and Tumors in the Gastrointestinal Tract:

  • Symptoms include being asymptomatic or having symptoms that are connected to the size and location of the polyps or tumors. These symptoms can include bleeding, pain, or blockage. Asymptomatic symptoms are rare.
    Upper endoscopy is indicated for a variety of diagnostic and therapeutic purposes, including the evaluation of tumors and polyps, as well as the determination of the nature of these growths.
    Inflammatory Bowel Disease (often referred to as IBD) and Its Complications:
  • Irritable bowel disease (IBD), also known as Crohn’s disease or ulcerative colitis, is characterized by gastrointestinal symptoms, such as diarrhea, stomach pain, and the presence of blood in the stool.
    It may be necessary to perform an EGD in IBD patients in order to determine whether or not the upper gastrointestinal tract is involved, whether problems have developed, or how well treatment is working.

Evaluation of Anemia That Cannot Be Explained

Symptoms include:

  • Abnormally low hemoglobin levels, however the underlying reason is unclear.
    Indication: EGD can uncover sources of bleeding in the gastrointestinal tract that may be contributing to anemia for which there is no known cause.
    The Initial Steps and the Process
  • Patients need to make preparations for the upper endoscopy operation before they may go through with it. As a standard part of this preparation, patients are instructed to abstain from food and drink starting several hours before the operation. This is done so that they can have clearer visualization throughout the examination.

During the course of the operation :

  • You will be sedated or given anesthetic so that the procedure will be as comfortable and stress-free as possible for you.
  • The endoscope will then be directed down the throat and into the upper gastrointestinal system after it has been gently inserted through the mouth.
  • The lining of the esophagus, stomach, and duodenum will be evaluated by the attending physician, who may also perform biopsies if deemed necessary.
  • The process can take anywhere from ten to thirty minutes, on average. Following the completion of the procedure, you will be observed for the remaining duration of the sedative’s effects. You might have some little pain, such as a sore throat, but it should only last for a short period of time in most cases.

Advantages of Upper endoscopy

When it comes to the diagnosis and treatment of problems in the upper gastrointestinal tract, upper endoscopy offers a number of benefits, including the following:

  1. Accurate Diagnosis Because EGD enables real-time viewing, medical professionals are able to precisely identify and analyze the underlying cause of patients’ complaints.
  2. Capabilities of Biopsy: The method enables the collection of tissue samples, also known as biopsies, which can be extremely helpful in the diagnosis of certain illnesses, such as malignancies and inflammatory disorders.
  3. Early Detection: Early detection with EGD can assist rapid treatment, perhaps avoiding the progression of disorders such as Barrett’s esophagus, esophageal cancer, and gastrointestinal bleeding. This is possible because early diagnosis can facilitate prompt therapy.
  4. Options for Treatment: Endoscopic gastroduodenoscopy (EGD) may be utilized in certain instances in order to carry out therapeutic treatments such as the removal of polyps, the treatment of bleeding lesions, or the dilatation of strictures.


Upper endoscopy, often known as EGD, is an extremely helpful diagnostic procedure that can investigate a wide variety of disorders and symptoms related to the upper gastrointestinal tract. An EGD can assist in determining the underlying reasons of symptoms such as persistent heartburn, unexplained abdominal pain, or a family history of gastrointestinal disorders, which can then direct treatment.

It is critical that you make an appointment with a healthcare provider if you continue to experience symptoms related to your upper gastrointestinal tract. They will assess your condition and decide whether or not an upper endoscopy is required based on their findings. People who struggle with difficulties in their upper gastrointestinal tract stand a better chance of having positive results and an enhanced quality of life if they receive an accurate diagnosis and suitable treatment early on.
