Gastroenteritis is a medical condition characterized by inflammation of the stomach and intestines, commonly caused by infection, producing symptoms like vomiting, diarrhea, and abdominal pain. It’s a multisystem issue primarily affecting the GI tract, often resulting from viral, bacterial, or parasitic agents. The term is used in clinical, public health, and everyday medical contexts.

Glaucoma is a medical condition characterized by increased intraocular pressure that can damage the optic nerve, potentially leading to vision loss. It is typically chronic and requires ongoing monitoring and treatment to prevent progression. The term is used broadly across ophthalmology and patient education, often with emphasis on early detection and management.

Hemangioma is a benign tumor made up of a tangle of small blood vessels. It typically appears as a red or purple lesion on the skin or within organs and is usually present at birth or develops shortly after. Most hemangiomas gradually involute over time, though some may require medical evaluation or intervention depending on location and growth.

Hematology is the branch of medicine that studies blood, its disorders, and blood-forming tissues. It covers laboratory analysis, diagnosis, and treatment of conditions such as anemia, leukemia, and clotting disorders. The term combines Greek roots for blood and study, and is used in medical education, clinical settings, and research to describe this specialized field.

A hematoma is a localized swelling filled with blood outside of a blood vessel, usually caused by injury. It forms when blood leaks from damaged capillaries and collects in surrounding tissues, producing a raised, sometimes discolored lump. The term is used in medical reporting and patient contexts to describe this collection of clotted blood beneath the skin or within organs.

Hemodialysis is a medical procedure that filters waste products and excess fluids from the blood when the kidneys cannot. It involves circulating blood through a dialyzer, a machine that cleanses it, typically via an access point in the circulatory system. This noun names the process used to treat kidney failure or severe kidney dysfunction.

Hepatic is an adjective relating to the liver. In medical contexts it is used to describe structures, conditions, or procedures involving the liver, such as hepatic tissue, hepatic cirrhosis, or hepatic function tests. It appears in clinical writing and anatomical discussions to specify liver-related aspects.

Hepatomegaly is the medical term for an enlarged liver. It is a noun used in clinical contexts to describe hepatomegaly of varying degrees, often indicating underlying hepatic disease or systemic illness. The word combines two Greek-derived elements and is commonly encountered in medical documentation and discussions of liver pathology.

Hernia is a medical condition in which an organ or tissue protrudes through an opening in the surrounding muscular or connective tissue. It commonly refers to abdominal contents pushing through the abdominal wall, but can involve other sites such as the groin or diaphragm. The term is used across clinical contexts and requires precise pronunciation to avoid miscommunication in medical discussions.

Herniation is the act or process of a structure, such as an organ or tissue, protruding through its usual boundary or an opening, often due to weakness or pressure. In medicine, it commonly refers to a portion of tissue (like an intervertebral disc or abdominal organ) pushing through a surrounding membrane or fascia. The term implies displacement rather than normal position, and is frequently used to describe pathological protrusion.

Histology is the branch of biology that studies the microscopic structure of tissues. It involves preparing thin tissue sections, staining them, and examining them under a microscope to understand tissue organization, cellular relationships, and function. The word combines Greek roots related to tissue and science, and it’s a foundational tool in pathology, anatomy, and biomedical research.

Hypertension is a medical condition characterized by persistently elevated blood pressure. It is a chronic risk factor for cardiovascular disease and stroke, requiring monitoring and lifestyle or pharmacological management. The term combines

Hypoglycemia is a medical condition characterized by an abnormally low level of blood glucose. It typically presents with symptoms like dizziness, sweating, and confusion, and requires prompt recognition and treatment. The term comes from Greek roots meaning “under” (hypo) and “sweet” (glycemia).

Hypokalemia is a medical condition characterized by an abnormally low level of potassium in the blood. It can cause muscle weakness, cramps, and arrhythmias, and may result from poor intake, diuretics, or diseases that influence potassium balance. Proper diagnosis relies on血 potassium measurements and clinical context, guiding treatment to restore potassium levels.

Hypotension is a medical condition characterized by blood pressure that's abnormally low. It can cause dizziness, fainting, or fatigue, particularly when standing. The term is commonly used in clinical contexts and research, contrasting with hypertension, and signals a potential risk requiring evaluation of heart rate, volume status, and autonomic function.

Hypothermia is a medical condition characterized by a dangerously low body temperature, typically below 35°C (95°F), caused by prolonged exposure to cold or impaired thermoregulation. It progresses through stages from mild shivering to severe hypothermia, where core temperature falls and vital functions are compromised. Prompt recognition and treatment are essential to prevent organ failure and death.

Hypoxemia is a medical condition characterized by low oxygen levels in the blood, typically measured as reduced arterial oxygen saturation. It can result from respiratory or circulatory dysfunction and may lead to tissue hypoxia if untreated. The term is commonly used in clinical settings and research to describe hypoxemic states.

Ileostomy is a surgical procedure creating an opening in the abdomen to divert the small intestine's contents into an external pouch. The term refers to the artificial ostomy (opening) of the ileum. It is a medical noun used in clinical discussions, patient education, and surgical planning, often described in terms of the stoma and its management.
