Diuresis is a physiological condition characterized by increased urine production. It results from pharmacological agents, certain diseases, or hormonal imbalances that promote diuresis. Clinically, it’s identified by elevated urine volume and can be temporary or chronic depending on the underlying cause.

Dysarthria is a motor-speech disorder characterized by impaired articulation caused by neurological weakness or incoordination. It affects the precision, speed, and clarity of spoken words, often producing slurred or mrop-tongue-like speech. The term covers various motor-imprecision patterns, stemming from brain or nerve problems, and is used in clinical and academic contexts to describe speech-intelligibility difficulties.

Dysplasia is a medical term referring to abnormal growth or development of tissue or organs, often indicating a deviation from the normal structure. It is not cancer in itself, but it can be associated with an increased risk of malignant change in some contexts. The word is used across anatomy, orthopedics, and pathology to describe irregular cellular organization.

Dyspnea is a medical noun meaning difficult or labored breathing. It is used to describe sensations of shortness of breath, often in clinical contexts. The term is technical and precise, typically found in healthcare discussions and patient notes rather than casual conversation.

Dystonia is a neurological movement disorder characterized by sustained or intermittent muscle contractions, causing twisting, repetitive movements, or abnormal postures. It can affect a single muscle group or multiple areas and may be painful or disabling, with symptoms that wax and wane. The term encompasses various focal and generalized forms and is diagnosed through clinical assessment and symptom patterns.

Edema is a medical term describing swelling caused by fluid accumulation in body tissues, often visible in extremities or dependent areas. It results from various conditions affecting circulation or lymphatic drainage. In medical contexts, edema is evaluated by location, cause, and severity, and may require treatment or monitoring.

Embolism is the blockage of a blood vessel by an embolus, such as a clot or air bubble, leading to impaired blood flow and potential tissue damage. It is a medical term used to describe obstruction that originates away from the site and travels to a narrower vessel. The word appears in clinical discussions of stroke, pulmonary embolism, and related vascular events.

Encephalitis is an inflammation of the brain tissue, usually due to infection or autoimmune processes. It can cause fever, headache, seizures, and altered mental status, sometimes with long-term neurologic effects. The term combines Greek roots for brain and inflammation, and it is used in clinical, academic, and research contexts.

Encephalopathy is a broad medical condition characterized by diffuse brain dysfunction or disease, not due to a focal structural issue. It reflects altered mental status, cognitive changes, and sometimes altered consciousness arising from metabolic, toxic, or infectious insults. The term is used across neurology and critical care to describe various acquired brain disorders.

Endarterectomy is a surgical procedure to remove a buildup of cholesterol or other material from an artery to restore normal blood flow. It is commonly performed on the carotid artery to prevent stroke. The term combines a prefix meaning within or interior artery with terms meaning removing. It is a specialized medical noun used in surgical contexts and medical communication.

Endocrinology is the branch of medicine and physiology concerned with the endocrine system and its hormones. It studies glands such as the pituitary, thyroid, and adrenals, how hormones are regulated, and how hormonal imbalances affect health. Professionals in this field diagnose, treat, and research disorders related to hormonal function.

Endometriosis is a chronic condition in which tissue similar to the lining of the uterus grows outside the uterine cavity, causing pain and potential fertility issues. It is not cancer, but it can lead to significant symptoms and complications. The term designates the disease process and location of abnormal endometrial-like tissue throughout the pelvis and beyond.

Endoscopy is a medical procedure that uses an endoscope to examine the interior surfaces of an organ or cavity. It involves inserting a flexible or rigid tube with a camera and light to visualize anatomy, obtain biopsies, or treat lesions. The term combines the Latin roots for inside (endo) and view (scopy).

Endothelium refers to the thin layer of cells that lines interior surfaces of blood vessels and lymphatic vessels. It forms a barrier between the circulating blood or lymph and the vessel wall, participates in vascular tone, coagulation, and immune responses. The term combines Greek roots for 'within' and 'skin,' and the suffix '-um' indicating a tissue or part.

Enteritis is a medical condition characterized by inflammation of the small intestine or, more broadly, the intestinal tract. It typically presents with symptoms like abdominal pain, diarrhea, and vomiting. Understanding the exact site and cause—infectious, inflammatory, or chemical—guides treatment and prognosis. The term combines Latin roots for intestine and inflammation, used mainly in clinical or academic contexts.

enterocele is a medical condition where part of the small intestine protrudes into the vaginal canal due to pelvic floor weakness. The term is used in clinical contexts and anatomy discussions, often described in exams and case studies. It is a specialized word that combines Greek roots for 'intestine' and 'hernial protrusion,' typically encountered by healthcare professionals.

Enterostomy is a surgical procedure that creates a stoma by opening a segment of the intestine or enteric tract to the abdominal wall. It allows drainage or diversion of intestinal contents. The term combines 'entero-' (intestine) with '-stomy' (mouth, opening).

Epiglottis is a small leaf-shaped flap of cartilage located behind the tongue that folds down to cover the windpipe during swallowing, helping to direct food toward the esophagus and away from the airway. It plays a crucial role in protecting respiration and guiding the larynx during swallowing. The term comes from Greek roots and is used in medical contexts and anatomy discussions.
