What are the key differences between a colonoscopy and an endoscopy?

Hello,

Glad to have you at icliniq.com.

I am here to extend a helping hand to you.

Both procedures are indicated in your case. Endoscopy is recommended for bloating, gas, and dyspepsia, especially if you are over 50 years old. A screening colonoscopy is also advised at least once if you are over 50.

The procedures differ:

1. Endoscopy, also known as gastroscopy, requires six to eight hours of fasting and is typically done with light anesthesia through the mouth. The procedure lasts around ten minutes and is generally safe for diagnostic purposes.
2. A colonoscopy focuses on the large intestine. Preparation involves a clear liquid diet without solid food for 24 to 36 hours, coupled with laxatives to induce diarrhea and clean the gut before the procedure. It is performed with mild anesthesia via the rectum and usually takes 15 to 30 minutes. This, too, is considered a safe procedure.
3. Risk factors are minimal, with rare occurrences of anesthesia reactions or procedure-related complications, typically happening in about one in thousands.

I hope this information has clarified your query. Feel free to reach out if you have more queries.

Thank you.
