An overview of common disorders and diseases of the digestive system, including inflammatory bowel disease, ulcers, and liver and pancreatic disorders.
Mouth and Teeth Anatomy: This topic covers the parts of the mouth and teeth and their functions in the digestive system.
Esophagus Anatomy: The esophagus is the muscular tube that connects the mouth to the stomach. This topic covers its functions and the structures that make it up.
Stomach Anatomy: The stomach is a muscular sac that stores and mixes food with digestive enzymes. This topic covers its anatomy and functions.
Small Intestine Anatomy: The small intestine is where most of the nutrients in food are absorbed. This topic covers its structure, anatomy, and functions.
Large Intestine Anatomy: The large intestine is where water is absorbed from the remaining food, and waste is prepared for elimination. This topic covers its anatomy and functions.
Liver Anatomy and Functions: The liver is an important organ that plays various functions in the digestive system, including producing bile, detoxifying the body, and storing glucose.
Pancreas Anatomy and Functions: The pancreas secretes digestive enzymes and hormones that regulate blood sugar levels.
Digestive Enzymes: Digestive enzymes play crucial roles in breaking down food into smaller molecules that can be absorbed by the body.
Nutrient Absorption: Nutrient absorption occurs in the small intestine and is the process by which nutrients from food are absorbed into the bloodstream.
Gastrointestinal Motility: Gastrointestinal motility refers to the movement of food through the digestive system, which is essential for proper digestion and elimination.
Hormones Involved in Digestion: Various hormones play critical roles in regulating digestive processes, including insulin, glucagon, and cholecystokinin.
Dysphagia: Dysphagia is a condition in which an individual has difficulty swallowing food or liquids, and it can cause complications such as malnutrition and dehydration.
Gastroesophageal Reflux Disease (GERD): GERD is a chronic condition in which stomach acid flows back into the esophagus, causing discomfort and damage.
Peptic Ulcers: Peptic ulcers are sores that develop in the lining of the stomach or small intestine and can cause bleeding, pain, and other complications.
Irritable Bowel Syndrome (IBS): IBS is a common disorder that affects the large intestine, causing symptoms such as abdominal pain, gas, and diarrhea or constipation.
Inflammatory Bowel Disease (IBD): IBD is a term used to describe several chronic conditions that cause inflammation in the digestive system, including Crohn's disease and ulcerative colitis.
Celiac Disease: Celiac disease is an autoimmune disorder in which the body reacts to gluten, a protein found in wheat, barley, and rye. It can lead to damage to the small intestine and malabsorption of nutrients.
Gallstones: Gallstones are hard deposits that form in the gallbladder and can cause various digestive problems, including abdominal pain and jaundice.
Pancreatitis: Pancreatitis is inflammation of the pancreas, which can cause severe pain and digestive problems.
Colorectal Cancer: Colorectal cancer is cancer that develops in the colon or rectum, and it is one of the most common types of cancer.
Gastroesophageal reflux disease (GERD): A condition that affects the muscles at the end of the esophagus, causing stomach acid to flow back into the esophagus, irritating the lining and causing heartburn.
Constipation: A condition in which bowel movements are infrequent, difficult or incomplete.
Diarrhea: A condition in which bowel movements are frequently loose and watery.
Irritable bowel syndrome (IBS): A chronic disorder that affects the large intestine, causing abdominal pain, bloating, constipation and diarrhea.
Celiac disease: A condition in which the small intestine becomes damaged in reaction to consuming gluten, a protein found in wheat, barley and rye.
Ulcerative colitis: A chronic disease that causes inflammation and sores (ulcers) in the lining of the large intestine and rectum.
Crohn's disease: A chronic inflammatory condition that can affect any part of the digestive tract, from the mouth to the anus.
Hemorrhoids: A condition in which the veins in the anus and rectum become swollen and inflamed.
Gallstones: Small, hard deposits that form in the gallbladder or bile ducts, causing abdominal pain and other symptoms.
Pancreatitis: Inflammation of the pancreas, which can lead to abdominal pain, nausea and vomiting.
Peptic ulcer disease: A condition in which sores develop on the lining of the stomach or small intestine, causing pain and discomfort.
Gastroparesis: A condition in which the muscles in the stomach don't work properly, causing delayed emptying of the stomach.
Diverticulitis: A condition in which small pouches (diverticula) in the wall of the colon become inflamed or infected.
Lactose intolerance: A condition in which the body is unable to digest lactose, a type of sugar found in milk and dairy products.
Gastroenteritis: Inflammation of the stomach and intestines, which can cause diarrhea, vomiting and other symptoms.
