Colonoscopy Test in Delhi

What is a Colonoscopy?

A colonoscopy is a procedure by which a doctor will closely look into your large intestine, known as the colon, and your rectum. It is done using a long, thin, flexible tube called a colonoscope, with a tiny camera and light at its tip. As the tube moves gently through the bowel, the camera sends clear images to a monitor to help the doctor find everything that looks unusual, such as polyps, swelling, bleeding, or early signs of cancer.

Why is Colonoscopy Done?

  • Persistent Heartburn or Acid Reflux (GERD): If one frequently experiences the feeling of some food or liquid getting stuck while swallowing, endoscopy helps in locating narrowing, strictures, or growths in the esophagus that might cause this problem. The doctor may treat minor narrowing during this procedure.
  • Difficulty Swallowing (Dysphagia): Chronic upper abdominal pain, discomfort, or bloating may point to ulcers, gastritis, or functional digestive disorders. The method of endoscopy provides a look directly into the stomach lining, helping to find the exact cause of pain.
  • Unexplained Stomach Pain or Bloating: When patients suddenly lose weight or have a loss of appetite for no apparent reason, endoscopy can rule out underlying causes such as tumors, inflammation, or digestive blockages.
  • Gastrointestinal (GI) Bleeding: This test is usually performed under mild sedation, therefore painless and comfortable for most patients. It provides important information unavailable through X-rays or scans, and aids in the diagnosis and early treatment of digestive disorders.
  • Weight Loss: When patients experience a sudden drop in weight or a decrease in appetite without clear reason, endoscopy helps rule out underlying causes such as tumors, inflammation, or digestive blockages.
