Anxiety: A feeling of apprehension and fear, characterized by physical symptoms such as palpitations, sweating, and feelings of stress.

Artery: A vessel that carries blood high in oxygen content away from the heart to the farthest reaches of the body. Since blood in arteries is usually full of oxygen, the hemoglobin in the red blood cells is oxygenated. The resultant form of hemoglobin (oxyhemoglobin) is what makes arterial blood look bright red.

Asthma: A common lung disorder in which inflammation causes the bronchi to swell and narrow the airways, creating breathing difficulties that may range from mild to life-threatening. Symptoms include shortness of breath, cough, wheezing, and chest tightness. The diagnosis of asthma is based on evidence of wheezing and is confirmed with breathing tests. Many allergens and irritants can precipitate attacks of asthma. Avoidance of precipitating factors can be helpful. Treatment may include lifestyle changes, activity reduction, allergy shots, and medications to prevent or reverse the bronchospasm.

Atropine: A drug, made from the belladonna plant, that is administered via injection, eye drops, or in oral form to relax muscles by inhibiting nerve responses.

Blurred vision: Lack of sharpness of vision with, as a result, the inability to see fine detail. Blurred vision can occur when a person who wears corrective lens is without them. Blurred vision can also be an important clue to eye disease.

Breathing: The process of respiration, during which air is inhaled into the lungs through the mouth or nose due to muscle contraction and then exhaled due to muscle relaxation.

Constipation: Infrequent and frequently incomplete bowel movements. Constipation is the opposite of diarrhea and is commonly caused by irritable bowel syndrome (IBS), diverticulosis, and medications. Paradoxically, constipation can also be caused by overuse of laxatives. Colon cancer can also narrow the colon and thereby cause constipation. A high-fiber diet can frequently relieve constipation. If the diet is not helpful, medical evaluation is warranted.

Coronary artery disease: Impedance or blockage of one or more arteries that supply blood to the heart, usually due to atherosclerosis (hardening of the arteries). Abbreviated CAD. A major cause of illness and death, CAD begins when hard cholesterol substances (plaques) are deposited within a coronary artery. The plaques in the coronary arteries can lead to the formation of tiny clots that can obstruct the flow of blood to the heart muscle, producing symptoms and signs of CAD, including chest pain (angina pectoris), heart attack (myocardial infarction), and sudden death. Treatment for CAD includes bypass surgery, balloon angioplasty, and the use of stents.

Diarrhea: A common condition that involves unusually frequent and liquid bowel movements. The opposite of constipation. There are many infectious and noninfectious causes of diarrhea. Persistent diarrhea is both uncomfortable and dangerous to the health because it can indicate an underlying infection and may mean that the body is not able to absorb some nutrients due to a problem in the bowels. Treatment includes drinking plenty of fluids to prevent dehydration and taking over-the-counter remedies. People with diarrhea that persists for more than a couple days, particularly small children or elderly people, should seek medical attention.

Dizziness: Painless head discomfort with many possible causes including disturbances of vision, the brain, balance (vestibular) system of the inner ear, and gastrointestinal system. Dizziness is a medically indistinct term which laypersons use to describe a variety of conditions ranging from lightheadedness, unsteadiness to vertigo.

Drain: A device for removing fluid from a cavity or wound. A drain is typically a tube or wick. As a verb, to allow fluid to be released from a confined area.

FDA: Food and Drug Administration.

Flush: (1) A redness of the skin, typically over the cheeks or neck. A flush is usually temporary and brought on by excitement, exercise, fever, or embarrassment. Flushing is an involuntary (uncontrollable) response of the nervous system leading to widening of the capillaries of the involved skin. Also referred to as a blush (or, as a verb, to blush). Flushing may also be caused by medications or other substances that cause widening of the capillaries, such as niacin. (2) Flush also means to wash out a wound or body area.

Generic: 1. The chemical name of a drug. 2. A term referring to the chemical makeup of a drug rather than to the advertised brand name under which the drug may be sold. 3.A term referring to any drug marketed under its chemical name without advertising.

Heart: The muscle that pumps blood received from veins into arteries throughout the body. The heart is positioned in the chest behind the sternum (breastbone); in front of the trachea, esophagus, and aorta; and above the diaphragm. A normal heart is about the size of a closed fist and weighs about 298 grams or 10.5 ounces. It is cone-shaped, with the point of the cone pointing down to the left. Two-thirds of the heart lies in the left side of the chest, with the balance in the right side of the chest. The heart is composed of specialized cardiac muscle, and it is four-chambered, with a right atrium and ventricle, and an anatomically separate left atrium and ventricle. The blood flows from the systemic veins into the right atrium, thence to the right ventricle, from which it is pumped to the lungs and then returned into the left atrium, thence to the left ventricle, from which it is driven into the systemic arteries. The heart is thus functionally composed of two hearts: the right heart and the left heart. The right heart consists of the right atrium, which receives deoxygenated blood from the body, and the right ventricle, which pumps the deoxygenated blood to the lungs under low pressure; and the left heart, which consists of the left atrium, which receives oxygenated blood from the lung, and the left ventricle, which pumps the oxygenated blood out to the body under high pressure.

Heart disease: Any disorder that affects the heart. Sometimes the term "heart disease" is used narrowly and incorrectly as a synonym for coronary artery disease. Heart disease is synonymous with cardiac disease but not with cardiovascular disease which is any disease of the heart or blood vessels. Among the many types of heart disease, see, for example: Angina; Arrhythmia; Congenital heart disease; Coronary artery disease (CAD); Dilated cardiomyopathy; Heart attack (myocardial infarction); Heart failure; Hypertrophic cardiomyopathy; Mitral regurgitation; Mitral valve prolapse; and Pulmonary stenosis.

Itching: An uncomfortable sensation in the skin that feels as if something is crawling on the skin and makes the person want to scratch the affected area. Itching is medically known as pruritis; something that is itchy is pruritic.

Medical history: 1. In clinical medicine, the patient's past and present which may contain relevant information bearing on their health past, present, and future. The medical history, being an account of all medical events and problems a person has experienced is an important tool in the management of the patient.
2. The history of medicine.

MedicAlert: A nonprofit emergency medical information service, known for its MedicAlert jewelry, particularly the bracelet, and its 24-hour emergency response center.

Megacolon: An abnormally enlarged colon. Megacolon can arise as a serious congenital problem in the newborn, caused by abnormal innervation of the colon and frequently requiring surgery.

Mouth: 1. The upper opening of the digestive tract, beginning with the lips and containing the teeth, gums, and tongue. Foodstuffs are broken down mechanically in the mouth by chewing and saliva is added as a lubricant. Saliva contains amylase, an enzyme that digests starch. 2. Any opening or aperture in the body. The mouth in both senses of the word is also called the os, the Latin word for an opening, or mouth. The o in os is pronounced as in hope. The genitive form of os is oris from which comes the word oral.

Muscle: Muscle is the tissue of the body which primarily functions as a source of power. There are three types of muscle in the body. Muscle which is responsible for moving extremities and external areas of the body is called "skeletal muscle." Heart muscle is called "cardiac muscle." Muscle that is in the walls of arteries and bowel is called "smooth muscle."

Myasthenia gravis: An autoimmune neuromuscular disorder that is characterized by fatigue and exhaustion of muscles. Abbreviated MG. MG is caused by a mistaken immune response to the body's own nicotinic acetylcholine receptors, which are found in junctions between muscles and the nervous system. The body produces antibodies that attack these receptors, preventing signals from reaching the muscles. A number of treatments are available that help, including steroids and other immunosuppressive medications and anticholinergic medications.

Nausea: Stomach queasiness, the urge to vomit. Nausea can be brought on by many causes, including systemic illnesses (such as influenza), medications, pain, and inner ear disease.

Nerve: A bundle of fibers that uses electrical and chemical signals to transmit sensory and motor information from one body part to another. The fibrous portions of a nerve are covered by a sheath called myelin and/or a membrane called neurilemma. (Note that entries for specific nerves can be found under the names of the particular nerves. For example, the optic nerve is not under 'nerve, optic' but rather under 'optic nerve.')

Panic: A sudden strong feeling of fear that prevents reasonable thought or action. The word comes from the name of the Greek woodland god Pan, who was a frightening figure'part human, part goat'and whose pet caprice was to terrify people who ventured into rural areas.

Parkinson's disease: A slowly progressive neurologic disease that is characterized by a fixed inexpressive face, tremor at rest, slowing of voluntary movements, gait with short accelerating steps, peculiar posture and muscle weakness (caused by degeneration of an area of the brain called the basal ganglia), and low production of the neurotransmitter dopamine. Most patients are over 50, but at least 10 percent are under 40. Treatment involves use of medication, such as levodopa (brand name: Larodopa) and carbidopa (brand name: Sinemet). A surgical procedure known as deep brain stimulation, in which externally controlled electrodes are implanted into the brain, has also been shown to be helpful. There are no blood or laboratory tests to diagnose the condition. Although it is a chronic and progressive disease, the degree of disability varies among affected persons. Also known as paralysis agitans and shaking palsy.

Pharmacist: A professional who fills prescriptions and, in the case of a compounding pharmacist, makes them. Pharmacists are very familiar with medication ingredients, interactions, and cautions.

Poison: Any substance that can cause severe organ damage or death if ingested, breathed in, or absorbed through the skin. Many substances that normally cause no problems, including water and most vitamins, can be poisonous if taken in excessive quantity. Poison treatment depends on the 'substance.

Poison control center: A special information center set up to inform people about how to respond to potential poisoning. These centers maintain databases of poisons and appropriate emergency treatment. Local poison control centers should be listed with other community-service numbers in the front of the telephone book, and they can also be reached immediately through any telephone operator.

Pregnancy: The state of carrying a developing embryo or fetus within the female body. This condition can be indicated by positive results on an over-the-counter urine test, and confirmed through a blood test, ultrasound, detection of fetal heartbeat, or an X-ray. Pregnancy lasts for about nine months, measured from the date of the woman's last menstrual period (LMP). It is conventionally divided into three trimesters, each roughly three months long.

Prescription: A physician's order for the preparation and administration of a drug or device for a patient. A prescription has several parts. They include the superscription or heading with the symbol "R" or "Rx", which stands for the word recipe (meaning, in Latin, to take); the inscription, which contains the names and quantities of the ingredients; the subscription or directions for compounding the drug; and the signature which is often preceded by the sign "s" standing for signa (Latin for mark), giving the directions to be marked on the container.

Pupil: The opening of the iris. The pupil may appear to open (dilate) and close (constrict), but it is really the iris that is the prime mover; the pupil is merely the absence of iris. The pupil determines how much light is let into the eye. Both pupils are usually of equal size. If they are not, the condition is called anisocoria.

Rash: Breaking out (eruption) of the skin. A rash can be caused by an underlying medical condition, hormonal cycles, allergies, or contact with irritating substances. Treatment depends on the underlying cause of the rash. Medically, a rash is referred to as an exanthem.

Saliva: a watery secretion in the mouth produced by the salivary glands that aids in the digestion of food. Saliva also serves to moisten and cleanse the mouth, including the tongue and teeth, and contains substances that can play a role in the prevention of infection. Saliva aids digestion by moistening food and contains enzymes that begin the digestion process. Also known as spit.

Substance: 1. Material with particular features.
2. The material that makes up an organ or structure. Also known in medicine as the substantia.

Surgery: The branch of medicine that employs operations in the treatment of disease or injury. Surgery can involve cutting, abrading, suturing, or otherwise physically changing body tissues and organs.

Sweating: The act of secreting fluid from the skin by the sweat (sudoriferous) glands. These are small tubular glands situated within and under the skin (in the subcutaneous tissue). They discharge by tiny openings in the surface of the skin.
See the entire definition of Sweating

Therapy: The treatment of disease. Therapy is synonymous with treatment.

Thyroid: 1. The thyroid gland. Also, pertaining to the thyroid gland. 2. A preparation of the thyroid gland used to treat hypothyroidism. 3. Shaped like a shield. (The thyroid gland was so-named by Thomas Wharton in 1656 because it was shaped like an ancient Greek shield.)
See the entire definition of Thyroid

Tired: A feeling of a lessened capacity for work and reduced efficiency of accomplishment, usually accompanied by a sense of weariness and fatigue.
See the entire definition of Tired

Ulcer: A lesion that is eroding away the skin or mucous membrane. Ulcers can have various causes, depending on their location. Ulcers on the skin are usually due to irritation, as in the case of bedsores, and may become inflamed and/or infected as they grow. Ulcers in the gastrointestinal tract were once attributed to stress, but most are now believed to be due to infection with the bacterium Helicobacter pylori. GI ulcers, however, are often made worse by stress, smoking, and other noninfectious factors.

Urinary: Having to do with the function or anatomy of the kidneys, ureters, bladder, or urethra. For example, the urinary tract is the collection of organs of the body that produce, store, and discharge urine.
