Gastroscopy, also known as Oesophago-Gastro-Duodenoscopy (OGD), is a safe and effective diagnostic procedure used to visualize the lining of the food pipe, stomach, and the small intestine. This procedure is done using a small and flexible tube known as an endoscope. Endoscopes are equipped with a tiny camera and light source that helps to view the lining of the digestive organs.
Gastroscopy is a common procedure used to diagnose and treat a variety of gastrointestinal issues. It can be used to identify sources of abdominal pain, heartburn, nausea, or other digestive issues. Gastroscopy can also be used to diagnose and treat conditions like ulcers, acid reflux, and hiatal hernia. This procedure can also be used to take biopsies for further diagnostic testing.
When is Gastroscopy Recommended?
Gastroscopy is typically recommended when a person is experiencing certain digestive symptoms and the cause of the symptoms is unknown or cannot be determined with traditional diagnostic tests. Some of the symptoms that may indicate the need for a gastroscopy include:
- Iron deficiency anemia
- Unexplained weight loss
- Upper abdominal discomfort or pain
- Recurrent or persistent vomiting and nausea
- Reflux symptoms such as acidic taste, throat symptoms, and heartburn
- Difficulty swallowing
- Black stool or blood present in the stools
In addition to diagnosing digestive problems, gastroscopy is also used to detect and remove precancerous growths, providing an important means of preventing the development of esophageal and stomach cancers. Patients with a high risk of developing these cancers may be advised to undergo gastroscopy as a preventive measure.
Gastroscopy is generally safe, though some patients may experience mild side effects such as nausea, vomiting, abdominal pain, or bloating. In general, these side effects are short-term and should resolve quickly. However, it is important to consult a doctor if the symptoms worsen or persist for an extended period of time.
How to Prepare for a Gastroscopy
Preparing for a gastroscopy can be daunting. But following a few simple steps can ensure that your procedure goes as smoothly as possible. Here’s what you need to know about preparing for a gastroscopy.
- Fasting: Fasting is a key part of preparing for a gastroscopy. You’ll need to fast for at least 6 hours prior to the procedure. This means no food or drink during that time. Your doctor may suggest that you fast longer, depending on your individual situation.
- Medications: Generally, most medications can be continued up until the procedure. However, you should avoid taking blood thinners or diabetic medications on the day of the procedure.
- Rest: After the procedure, you should rest and avoid strenuous activities. You should also avoid driving or operating machinery for at least 24 hours after the procedure.
These are just a few tips to help you prepare for a gastroscopy. Following these recommendations can help ensure that the procedure is as safe and successful as possible. Of course, it’s always important to consult with your doctor about any questions or concerns you may have about the procedure.
What to Expect During Gastroscopy
During the procedure, you will be given medication to make you relax, and you may be given a local anesthetic spray to numb the area being examined. The procedure usually takes around 10-20 minutes.
Following the procedure, your doctor will discuss the gastroscopy findings and any biopsies taken. Your doctor may also discuss the appropriate management plan and any precautions or possible complications associated with the procedure.
Gastroscopy is generally a safe and effective procedure that can help diagnose and treat a variety of stomach issues. If you have any questions or concerns, it’s important to discuss them with your doctor before the procedure.
Gastroscopy is an important diagnostic tool for identifying digestive problems and ensuring early detection and treatment of any serious underlying issues. If you are experiencing any of the aforementioned symptoms, it is important to speak to your doctor about whether or not gastroscopy is the best option for you.
