    • Making proteins that help in blood clotting

  • Colonoscopy

    Colonoscopy is a procedure used to view the large intestine (colon and rectum) using an instrument called a colonoscope, a flexible tube with a small camera and light source attached to its tip. Colonoscopy can be performed for screening or diagnostic purposes. While diagnostic colonoscopy is performed to confirm the presence of colorectal cancer or colorectal polyps from a person showing symptoms (blood in stools, anemia, etc.), screening colonoscopy is performed on an asymptomatic person without any prior history of the two conditions.

  • Acid Reflux

    Gastroesophageal reflux disease (GERD) is a condition where the stomach acid leaks into your food pipe (esophagus) causing a burning sensation in your chest and other associated symptoms.

    Everyone experiences acid reflux once in a while after a heavy meal or when lying down. However, people with GERD experience acid reflux on a regular basis, often more than twice a week, and it could lead to serious health concerns and negatively impact quality of life.

  • Hemorrhoids

    Hemorrhoids may be external or internal. If they develop inside the rectum, they are called internal hemorrhoids. External hemorrhoids develop around the anus just below the skin. Some of the external hemorrhoids develop blood clots and are quite painful. They are called thrombosed hemorrhoids. Another type of piles is so large that they often protrude during defaecation. They are called prolapsing piles.

  • Celiac Disease

    Celiac disease is a condition characterized by inflammation of the lining of the small intestine due to an autoimmune reaction (body’s immune system mistakenly attacks own healthy tissues) against gluten, a protein found in foods such as oats, wheat, rye, and barley. Intake of such foods may lead to gastrointestinal and malabsorptive problems.

  • Endoscopy

    Upper GI endoscopy is usually performed on an outpatient basis. The endoscope is a long, thin, flexible tube with a tiny video camera and light on the end. By adjusting the various controls on the endoscope, the endoscopist can safely guide the instrument to carefully examine the inside lining of the upper digestive system. Upper GI Endoscopy The high-quality picture from the endoscope is shown on a TV monitor; it gives a clear, detailed view. In many cases, upper GI endoscopy is a more precise examination than X-ray studies.

  • Colon Cancer

    Colon cancer is the growth of rapidly dividing cells in the large intestine. Cancer of the colon develops from polyps, the small and non-cancerous growths of tissues. Colon cancer usually begins in glands lining the colon and rectum. Colon cancer initially begins as a non-cancerous tumor and gradually develops into cancer which spreads to other tissues.

  • Inflammatory
    Bowel Disease

    Inflammatory bowel disease (IBD), as the name implies, refers to an inflammatory condition of the bowel or gastrointestinal (GI) tract. It is a group of disorders characterized by inflammation of the bowel or any part of the GI tract. Though the exact cause of the condition remains unknown, the genetic and non-genetic or environmental factors are thought to play a part. All these factors may impair the normal functioning of the immune system and the body's defence mechanism attacks the body's own tissue causing inflammation of the mucosal lining.

  • GERD/Heartburn

    Gastroesophageal reflux disease (GERD) is a condition where the stomach acid leaks into your food pipe (esophagus) causing a burning sensation in your chest and other associated symptoms.

    Everyone experiences acid reflux once in a while after a heavy meal or when lying down. However, people with GERD experience acid reflux on a regular basis, often more than twice a week, and it could lead to serious health concerns and negatively impact quality of life.

  • Diverticulitis

    The intestine is divided into the large and small intestine. The large intestine absorbs nutrients from the food that you eat and pushes the remaining undigested waste towards the anus. High fibrous foods like fruits and vegetables soften the undigested material and help in easy movement of stools. However, low-fiber foods can produce small and hard stools that are expelled with increased strain while passing. This straining can create weak spots in the wall of the intestine leading to diverticular diseases, conditions that cause the development of small sacs or pouches. The conditions include diverticulosis, diverticular bleeding, and diverticulitis.
