Why Would I Need a Gastroscopy?

If you’ve ever experienced digestive issues or persistent discomfort in your upper abdomen, you may have heard of a procedure called gastroscopy. Also known as an upper endoscopy, this medical examination allows healthcare professionals to closely inspect the upper gastrointestinal tract.

In this article, we will explore the reasons why you might need a gastroscopy and how it can provide valuable insights into your digestive health. If you’re in the Toronto area, Canadian Place Endoscopy is a trusted gastroscopy clinic where you can receive this procedure.

Gastroscopy is a versatile and crucial diagnostic tool used by gastroenterologists to evaluate and diagnose various conditions of the upper digestive system, which includes the esophagus, stomach, and the first part of the small intestine (duodenum). Here are some common reasons why you might be recommended for a gastroscopy:

    • Unexplained Upper Abdominal Discomfort:

If you frequently experience pain, burning sensations, or discomfort in your upper abdomen and the cause remains unknown, a gastroscopy can help identify the underlying issue. This procedure can diagnose and assess conditions such as gastritis, peptic ulcers, or gastroesophageal reflux disease (GERD).

    • Difficulty Swallowing:

Dysphagia, or difficulty swallowing, can be caused by a variety of factors, including the narrowing of the esophagus, the presence of abnormal growths (such as tumors or strictures), or inflammation. A gastroscopy can provide insights into the cause of your swallowing difficulties.

    • Chronic Heartburn:

Gastroesophageal reflux disease (GERD) is a common condition that can lead to chronic heartburn, regurgitation, and other symptoms. A gastroscopy can help determine the extent of esophageal damage and guide treatment options.

    • Evaluation of Gastrointestinal Bleeding:

If you have been experiencing gastrointestinal bleeding, a gastroscopy can help pinpoint the source of the bleeding, whether it’s from ulcers, inflammation, or other lesions. This information is crucial for determining the appropriate treatment plan.

    • Screening for Cancer:

In some cases, a gastroscopy is performed as a preventive measure to screen for esophageal or stomach cancer, especially if you have risk factors like a family history of these diseases or long-standing conditions such as Barrett’s esophagus.

    • Biopsy and Tissue Sampling:

During a gastroscopy, the gastroenterologist can take tissue samples (biopsies) for analysis. This is essential for diagnosing conditions like celiac disease, certain infections, or early stages of esophageal cancer.

    • Treatment Procedures:

In addition to diagnosis, a gastroscopy can be used to perform various therapeutic procedures. For instance, if we detect a polyp or abnormal growth, we can remove it during the same procedure, avoiding the need for additional surgeries.

When considering a gastroscopy, it’s important to choose a reputable medical facility, such as the Gastroscopy clinic in Toronto. They have a team of experienced gastroenterologists and state-of-the-art equipment to ensure a thorough and accurate examination. It’s crucial to have confidence in the professionals conducting the procedure, as they can provide you with precise results and guide you toward the most appropriate treatment options.

The gastroscopy procedure itself is relatively straightforward. Typically, it takes around 15-30 minutes, during which we will comfortably sedate you to minimize any discomfort. Gently insert a thin, flexible tube called an endoscope through the mouth and guide it through the upper digestive tract. The endoscope contains a camera that provides real-time imaging on a monitor, allowing the gastroenterologist to closely examine the lining of the esophagus, stomach, and duodenum.

After the procedure, you may experience mild throat discomfort and bloating, but these side effects typically subside within a few hours. It’s important to follow your healthcare provider’s instructions regarding fasting and post-procedure care.


Gastroscopy diagnoses various upper GI issues, from pain to cancer screening, making it a valuable diagnostic tool.
