The GI tract could be a series of hollow organs that type an extended continuous passage from our mouth to our anus. The organs that make up our GI tract are our mouth, esophagus, stomach, small intestine, large intestine, and anus.

The liver is an organ about the size of a football that sits just under your rib cage on the right side of your abdomen. The liver is essential for digesting food and ridding your body of toxic substances. The liver plays an important role in many bodily functions from protein production and blood clotting to cholesterol, glucose (sugar), and iron metabolism, damage to the liver results in scarring (cirrhosis), which can lead to liver failure, a life-threatening condition. Excessive amount of certain drugs causes liver diseases

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 speciality. Gastroenterologists perform a number of diagnostic and therapeutic procedures

Metabolic syndrome is a collection of risk factors that increase the chance of developing heart disease, stroke, and diabetes. Lifestyle changes like losing weight, exercise, and dietary changes can help prevent or reverse metabolic syndrome

Diabetes is a condition that impairs the body's ability to process blood glucose, otherwise known as blood sugar. 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. Insulin is a hormone that comes from a gland situated behind and below the stomach pancreas. The pancreas secretes insulin into the bloodstream. The insulin circulates, enabling sugar to enter your cells. Insulin lowers the amount of sugar in your bloodstream. As your blood sugar level drops, so does the secretion of insulin from your pancreas.

The complexity and magnitude of medical advances in the management of digestive diseases make it ever more challenging for clinicians to apply this tremendous amount of information to their practice. Digestive disorders include the treatment of diseases of the liver and digestive tract, including the stomach, duodenum, gallbladder, biliary tract, pancreas, small intestine and colon. A range of medical professionals could be needed to treat digestive disorders: GPs, dietitians, gastroenterologists, endocrinologists, proctologists, ear- nose- and throat specialists and surgeons. Many digestive disorders have similar symptoms such as nausea, diarrhoea and abdominal pain

The gastrointestinal tract (GIT) consists of a hollow muscular tube starting from the oral cavity, where food enters the mouth, continuing through the pharynx, oesophagus, stomach and intestines to the rectum and anus, where food is expelled. There are various accessory organs that assist the tract by secreting enzymes to help break down food into its component nutrients. Thus the salivary glands, liver, pancreas and gall bladder have important functions in the digestive system. Food is propelled along the length of the GIT by peristaltic movements of the muscular walls

Gastritis is an inflammation, irritation, or erosion of the lining of the stomach. It can occur suddenly (acute) or gradually (chronic). Gastritis can be caused by irritation due to excessive alcohol use, chronic vomiting, stress, or the use of certain medications such as aspirin or other anti-inflammatory drugs

Molecular biology has become an integral part of basic and clinical gastroenterology. A broad spectrum of infectious, inherited and malignant gastrointestinal diseases can now be studied by molecular methods, including polymerase chain reaction, hybridization and DNA sequence analyses. Recent progress in the molecular analysis of Whipple’s disease and colorectal cancer

The pancreas is a large gland behind the stomach and next to the small intestine. The pancreas does two main things it releases powerful digestive enzymes into the small intestine to aid the digestion of food, It releases the hormones insulin and glucagon into the bloodstream. These hormones help the body control how it uses food for energy

Hepato-pancreato-biliary disease refers to any condition that affects the liver, pancreas, gallbladder, and the bile ducts. These diseases commonly share some tell-tale signs or symptoms, such as jaundice, darker urine colour, and lighter stool colour. While some have genetic or hereditary causes, most are due to chronic damage to the tissues of the organs involved. These conditions are treated and managed by hepatologists, hepato-pancreato-biliary oncologists, and transplant specialists

Gastrointestinal surgery is a treatment for diseases of the parts of the body involved in digestion. This includes the esophagus, stomach, small intestine, large intestine, and rectum. It also includes the liver, gallbladder, and pancreas. Surgery may be used to remove a cancerous or noncancerous growth or damaged part of the body, such as the intestine. It may also be used to repair a problem like a hernia. Minor surgical procedures are used to screen and diagnose problems of the digestive system
