• Gastroenterology

    Gastroenterology is the branch of medicine focused on the digestive system and its disorders. Diseases affecting the gastrointestinal tract, which include the organs from mouth into anus, along the alimentary canal, are the focus of this specialty. Physicians practicing in this field are called gastroenterologists.

  • Pediatric Gastroenterology

    Pediatric gastroenterology developed as a sub-specialty of pediatrics and gastroenterology. It is concerned with treating the gastrointestinal tract, liver and pancreas of children from infancy until age eighteen.

  • Digestive Disorders

    Digestive diseases are disorders of the digestive tract, which is sometimes called the gastrointestinal (GI) tract. In digestion, food and drink are broken down into small parts (called nutrients) that the body can absorb and use as energy and building blocks for cells. The digestive tract is made up of the esophagus (food tube), stomach, large and small intestines, liver, pancreas, and the gallbladder.

  • Microbiota and diseases

    The human gut microbiome has been associated with many health factors but variability between studies limits exploration of effects between them. Describing several novel associations, highlight associations common across multiple diseases, and determine which diseases and medications have the greatest association with the gut microbiota.

  • Gastrointestinal Bleeding

    Gastrointestinal bleeding (GI bleed), also known as gastrointestinal hemorrhage, is all forms of bleeding in the gastrointestinal tract, from the mouth to the rectum. When there is significant blood loss over a short time, symptoms may include vomiting red blood, vomiting black blood, bloody stool, or black stool. 

  • Gastrointestinal Oncology

    Gastrointestinal cancers are among the most challenging cancers to treat. Patients not only have access to surgery, chemotherapy and radiation therapy, but also to innovative options, such as cryoablation, biological therapies and even supportive care services to help improve their quality of life. Possible spectrum of treatment options include Endoscopic, laparoscopic and minimally invasive surgery; Novel chemotherapy drugs; Interventional radiology; Functional imaging; Molecular therapies and immunotherapies; Pain management; Risk assessment, screening, early detection and prevention method.

  • Gallbladder and biliary tract Diseases

    Gallbladder diseases considered here include gallstones, tumors, and acute acalculous cholecystitis. Gallbladder stones are an extremely common disorder and are usually asymptomatic. Some patients experience biliary colic, an intermittent and often severe pain in the epigastrium or right upper quadrant, and at times between the scapula because of temporary obstruction of the cystic duct with a gallstone. If the cystic duct obstruction persists, the gallbladder becomes inflamed and the patient develops cholecystitis, an acute inflammation and infection of the gallbladder.

  • Liver Diseases & Hepatitis

    Parasites and viruses can infect the liver, causing inflammation that reduces liver function. The viruses that cause liver damage can be spread through blood or semen, contaminated food or water, or close contact with a person who is infected. The most common types of liver infection are hepatitis viruses, including: Hepatitis A; Hepatitis B; Hepatitis C. 

  • Diabetics

    Diabetes mellitus refers to a group of diseases that affect how your body uses blood sugar (glucose). Glucose is vital to your health because it's an important source of energy for the cells that make up your muscles and tissues. It's also your brain's main source of fuel. The underlying cause of diabetes varies by type. But, no matter what type of diabetes you have, it can lead to excess sugar in your blood. Too much sugar in your blood can lead to serious health problems. Chronic diabetes conditions include type 1 diabetes and type 2 diabetes. Potentially reversible diabetes conditions include prediabetes — when your blood sugar levels are higher than normal, but not high enough to be classified as diabetes — and gestational diabetes, which occurs during pregnancy but may resolve after the baby is delivered.

  • Esophageal disease

    Barrett's esophagus is a serious complication of GERD, which stands for gastroesophageal reflux disease. In Barrett's esophagus, normal tissue lining the esophagus -- the tube that carries food from the mouth to the stomach -- changes to tissue that resembles the lining of the intestine.

  • Pancreatic Diseases

    There are a variety of disorders of the pancreas including acute pancreatitis, chronic pancreatitis, hereditary pancreatitis, and pancreatic cancer. The evaluation of pancreatic diseases can be difficult due to the inaccessibility of the pancreas. There are multiple methods to evaluate the pancreas. Initial tests of the pancreas include a physical examination, which is difficult since the pancreas is deep in the abdomen near the spine. Blood tests are often helpful in determining whether the pancreas is involved in a specific symptom but may be misleading. The best radiographic tests to evaluate the structure of the pancreas include CAT (computed tomography) scan, endoscopic ultrasound, and MRI (magnetic resonance imaging). Tests to evaluate the pancreatic ducts include ERCP (endoscopic retrograde cholangiopancreatography) and MRCP(magnetic resonance cholangiopancreatography). There are also instances in which surgical exploration is the only way to confirm the diagnosis of pancreatic disease.

  • Gastrointestinal immunology

    Gastrointestinal Immunology mainly focus on differentiation of gut-associated lymphoid tissue, regulation of innate and adaptive immune cell differentiation and function, genetic and epigenetic factors regulating immune responses and inflammation. It also gives idea about the clinical research, clinical trials and epidemiology studies on gastrointestinal inflammatory diseases including but not limited to gluten-sensitive enteropathy, inflammatory bowel disease, and gastritis, malabsorption syndromes, diarrhea, gastric and duodenal ulcers and disease of the salivary glands excluding cystic fibrosis.

  • Neurogastroenterology

    Neurogastroenterology is a subspecialty of gastroenterology that overlaps with neurology. The enteric nervous system is a collection of neurones that can function independently of the central nervous system (CNS). This article discusses the neurologic manifestations of gastroenterological disorders as well as significant gastroenterological manifestations of neurologic disorders. The CNS plays a role in the pathogenesis of some gastrointestinal disorders. Management depends on the individual disorder. Some general approaches to treatment of various gastrointestinal manifestations of neurologic disease are outlined in this article. Among the specialized procedures in development, transplantation of neural stem cells is a promising therapeutic approach for disorders of the enteric nervous system.

  • Gastrointestinal Pathology

    The main purpose of the gastrointestinal tract is the transport of food and the absorption of nutrients. Many pathologic conditions of the gastrointestinal tract impair either or both of these functions. The gastrointestinal tract, and especially the colon, is a common site of malignancy. The two main symptoms related to pathology of the gastrointestinal tract are abdominal pain and gastrointestinal hemorrhage.

  • Clinical Gastroenterology

  • Gastrointestinal Endoscopy

    Upper endoscopy, also referred to as oesophagogastroduodenoscopy (OGD), is a procedure that allows a doctor to examine the state of the upper gastrointestinal tract (i.e. the oesophagus, stomach and duodenum). The procedure will usually be performed by a gastroenterologist or upper gastrointestinal general surgeon. It involves the insertion of an endoscope (a long flexible tube with a camera at the end) into the gastrointestinal tract through the mouth. It can be done with the patient alert or under general anesthesia. Other techniques includes Capsule endoscopy, Endoscopic Retrograde Cholangiopancreatography (ERCP), Colonoscopy, Flexible sigmoidoscopy. 

  • Gastrointestinal Radiology

    Gastroenterologists often order radiographic tests to help diagnose diseases of the gastrointestinal tract. Common complaints that may lead to such testing include abdominal pain, nausea, vomiting, heartburn, diarrhea, and constipation, blood in the stool, bloating, weight loss, and abnormal laboratory tests. Fluoroscopy is an imaging technique that uses X-rays to obtain real-time moving images of the internal structures of a patient through the use of a fluoroscope allowing the images to be recorded and played on a monitor. Barium Sulfate is commonly used to allow for better visualization of gastrointestinal organs. Barium sulfate is a harmless chalky, water-insoluble compound that does not permit x-rays to pass through it. Taken before or during an examination, it causes the intestinal tract to stand out in silhouette when viewed through a fluoroscope or seen on an x-ray film. It is important to evacuate the barium completely following the study; a mild laxative is usually prescribed for this purpose.

  •  Bariatric Surgery

    Bariatric surgical procedures cause weight loss by restricting the amount of food the stomach can hold, causing malabsorption of nutrients, or by a combination of both gastric restriction and malabsorption. Bariatric procedures also often cause hormonal changes. Most weight loss surgeries today are performed using minimally invasive techniques (laparoscopic surgery). The most common bariatric surgery procedures are gastric bypass, sleeve gastrectomy, adjustable gastric band, and biliopancreatic diversion with duodenal switch. Each surgery has its own advantages and disadvantages.

  • Recent Advances in Gastroenterology

    In recent years, there have been incredible advancements in the gastrointestinal and hepatology space. These include innovations in colorectal cancer screening, capsule endoscopy, cures for hepatitis C and new biologic therapies, among many others. While these developments have been exciting and moved the field forward, the way we deliver care has remained largely unchanged. Today's healthcare delivery model centers around the 15 to 30 minute clinic visit, yet patients spend 99.9 percent of their lives outside of the clinic either at home, at work or at play. Having so few touchpoints can make it untenable for providers to gather months’ worth of information from the patient, make an assessment, and have an informed discussion all in the span of a short clinic visit. This is where digital health innovations, particularly smartphone apps, have the potential to change (and hopefully improve) the way we deliver care by tapping into the lives of patients when they are outside of the clinic.
