Liver Elastography is a noninvasive way to estimate how stiff the liver tissue is. Liver stiffness often changes with liver scarring (fibrosis) and some types of inflammation or congestion. It is commonly used in hepatology clinics to evaluate chronic liver disease without a biopsy. It can be performed with ultrasound-based methods or magnetic resonance imaging (MRI).
Fulminant Hepatitis is a rapidly progressive form of acute liver injury that can lead to acute liver failure. It is commonly discussed in hepatology, emergency medicine, and intensive care because it can deteriorate quickly. In plain terms, it means the liver suddenly stops performing key functions over days to weeks. The term is used to communicate urgency, guide evaluation, and trigger transplant-center level care planning.
Acute Liver Injury is a clinical term for recent liver cell or bile-duct–related damage detected over days to weeks. It is most commonly recognized through abnormal liver blood tests (liver enzymes and bilirubin). It is used in hospitals and clinics to describe a pattern that needs timely evaluation. It is not the same diagnosis as acute liver failure, which implies severe loss of liver function.
Chronic Liver Disease is an umbrella term for long-standing liver injury that persists for months to years. It is commonly used in clinical notes, problem lists, and teaching to describe ongoing liver inflammation, scarring (fibrosis), or impaired liver function. It can range from mild, stable disease to advanced cirrhosis with complications. In practice, the term helps clinicians communicate severity, cause, and monitoring needs.
Post Infectious IBS is a subtype of irritable bowel syndrome (IBS) that begins after an episode of infectious gastroenteritis. It describes ongoing bowel symptoms such as abdominal pain and altered stool pattern after the acute infection has resolved. It is most commonly used in outpatient gastroenterology and primary care to frame a specific clinical history of “IBS after a gut infection.” It is a clinical diagnosis based on symptoms and context rather than a single definitive test.
Functional Constipation is a diagnosis used when constipation symptoms are present without an identifiable structural, metabolic, or medication-related cause. It is defined using symptom-based criteria, most commonly the Rome IV criteria, rather than a single lab test or imaging finding. Clinicians use it in outpatient gastroenterology and primary care to describe chronic constipation patterns and guide evaluation. It is also used in research and clinical documentation to standardize how constipation is described across patients.
Functional Dyspepsia is chronic or recurrent upper abdominal discomfort without an identifiable structural cause on routine evaluation. It is commonly used as a clinical diagnosis in gastroenterology when symptoms suggest stomach or duodenal disease but tests are unrevealing. In plain terms, it describes “indigestion” symptoms that persist even when no ulcer, cancer, or obvious inflammation is found. It is discussed in clinics, endoscopy units, and primary care because it is a frequent reason for upper gastrointestinal (GI) symptom evaluation.
Visceral Hypersensitivity means the internal organs feel pain or discomfort more easily than expected. It describes heightened sensing from the gastrointestinal (GI) tract or other abdominal organs. It is commonly discussed in functional GI disorders, such as irritable bowel syndrome (IBS). Clinicians also use it to interpret symptoms when tests do not show clear structural disease.
Leaky Gut is a nontechnical term that usually refers to increased intestinal permeability. It describes a situation where the gut lining allows more substances to pass from the intestinal lumen into the body than expected. The phrase is common in popular health discussions and also appears in research contexts. In clinical practice, clinicians more often use precise terms like “intestinal barrier dysfunction” rather than Leaky Gut.
Intestinal Permeability describes how easily substances pass from the gut lumen into the body across the intestinal lining. It is a normal physiologic property that supports nutrient and water absorption while limiting harmful exposures. In clinical medicine, the term is commonly used when discussing barrier function, inflammation, infection, and certain GI disorders. It may also refer to how permeability is *measured* in research or selected clinical settings.
