Belching: A normal process to relieve distention from the air that accumulates in the stomach. The upper abdominal discomfort associated with excessive swallowed air may extend into the lower chest, producing symptoms suggesting heart or lung 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.

Bronchitis: Inflammation and swelling of the bronchi. Bronchitis can be acute or chronic.

Cure: 1. To heal, to make well, to restore to good health. Cures are easy to claim and, all too often, difficult to confirm.
2. A time without recurrence of a disease so that the risk of recurrence is small, as in the 5-year cure rate for malignant melanoma.
3. Particularly in the past, a course of treatment. For example, take a cure at a spa.

Drip: In medical usage, a drip is not a dull, unattractive person but a device for administering a fluid drop-by-drop into a vein. It is an intravenous (IV) fluid dripping into a vein, an intravenous fluid drip, a solution (usually a balanced electrolyte solution) administered directly into the venous circulation. It is, for short, an IV.

Dry mouth: The condition of not having enough saliva to keep the mouth wet. This is due to inadequate function of the salivary glands. Everyone has dry mouth once in a while when they are nervous, upset or under stress. But if someone has a dry mouth most all of the time, it can be uncomfortable and lead to serious health problems.

Exacerbate: To make worse. For example, smoking may exacerbate systemic lupus erythematosus.

Family history: The family structure and relationships within the family, including information about diseases in family members.
See the entire definition of Family history

Fever: Although a fever technically is any body temperature above the normal of 98.6 degrees F. (37 degrees C.), in practice a person is usually not considered to have a significant fever until the temperature is above 100.4 degrees F (38 degrees C.).

Fluoride: A compound of fluorine with another element or radical. Fluoride compounds are present in drinking water and some foods. Fluoride ions replace hydroxyl ions in hydroxyapatite in teeth, forming fluorapatite, which leads to fewer cavities. Fluoride compounds are therefore added to some toothpastes and dentists may also give a yearly fluoride treatment. It is generally recommended that fluorides be added to water supplies in which the natural level is less than 0.7 ppm in water to increase the concentration to 0.7-1.2 ppm. The addition of fluoride to water systems is one of the major achievements in public health in the 20th century. Fluoride, in combination with calcium and vitamin D, also increases bone mass and lowers the risk of backbone fractures associated with osteoporosis. The only accepted adverse effect of fluoridation is dental fluorosis. See also: Water fluoridation.

Garlic: A perennial herb of the lily family cultivated for its pungent, edible bulbs. Garlic has been used with the intention of lowering blood pressure and cholesterol.

Gastroesophageal: Pertaining to both the stomach and the esophagus, as in the gastroesophageal junction, the place where the esophagus connects to the stomach.

Gastroesophageal reflux: The return of stomach contents back up into the esophagus This frequently causes heartburn because of irritation of the esophagus by stomach acid.
See the entire definition of Gastroesophageal reflux

Gastrointestinal: Adjective referring collectively to the stomach and small and large intestines.
See the entire definition of Gastrointestinal

GERD: Stands for Gastroesophageal Reflux Disease, a disorder in which there is recurrent return of stomach contents back up into the esophagus, frequently causing heartburn, a symptom of irritation of the esophagus by stomach acid. This can lead to scarring and stricture of the esophagus, which can require stretching (dilating).

Gland: 1. A group of cells that secrete a substance for use in the body. For example, the thyroid gland. 2. A group of cells that removes materials from the circulation. For example, a lymph gland.

Gum disease: Inflammation of the soft tissue (gingiva) and abnormal loss of bone that surrounds the teeth and holds them in place. Gum disease is caused by toxins secreted by bacteria in "plaque" that accumulate over time along the gum line. This plaque is a mixture of food, saliva, and bacteria. Early symptoms of gum disease include gum bleeding without pain. Pain is a symptom of more advanced gum disease as the loss of bone around the teeth leads to the formation of gum pockets. Bacteria in these pockets cause gum infection, swelling, pain, and further bone destruction. Advanced gum disease can cause loss of otherwise healthy teeth.

Halitosis: bad breath. Causes of halitosis include dietary factors, poor oral hygiene, tobacco use, certain chronic medical conditions, or dry mouth (as a side effect of medications, from mouth breathing, or from problems with the salivary glands leading to decreased production of saliva).

Hygiene: The science of preventive medicine and the preservation of health. From the name of Hygeia, the daughter of Asklepios, the Greek god of medicine (whose staff with entwined snake is the symbol of medicine). Asklepios (known to the Romans as Aesculapius) had a number of children including not only Hygeia but also Panaceia, the patroness of clinical medicine. Hygeia also followed her father into medicine. As the patroness of health, Hygeia was charged with providing a healthy environment to prevent illness. In Greek, "hygieia" means health.

Infant: A child up to 2 years (24 months) of age.

Infection: The growth of a parasitic organism within the body. (A parasitic organism is one that lives on or in another organism and draws its nourishment therefrom.) A person with an infection has another organism (a "germ") growing within him, drawing its nourishment from the person.
See the entire definition of Infection

Kidney: One of a pair of organs located in the right and left side of the abdomen which clear "poisons" from the blood, regulate acid concentration and maintain water balance in the body by excreting urine. The kidneys are part of the urinary tract. The urine then passes through connecting tubes called "ureters" into the bladder. The bladder stores the urine until it is released during urination.

Lactose: The sugar found in milk. Lactose is a large sugar molecule that is made up of two smaller sugar molecules, glucose and galactose. In order for lactose to be absorbed from the intestine and into the body, it must first be split into glucose and galactose. The glucose and galactose are then absorbed by the cells lining the small intestine. The enzyme that splits lactose into glucose and galactose is called lactase, and it is located on the surface of the cells lining the small intestine.
See the entire definition of Lactose

Lactose intolerance: Inability to digest lactose, a component of milk and most other dairy products. Lactose is sometimes also used as an ingredient in other foods, so those with a lactase deficiency should check labels carefully.
See the entire definition of Lactose intolerance

Liver: An organ in the upper abdomen that aids in digestion and removes waste products and worn-out cells from the blood. The liver is the largest solid organ in the body. The liver weighs about three and a half pounds (1.6 kilograms). It measures about 8 inches (20 cm) horizontally (across) and 6.5 inches (17 cm) vertically (down) and is 4.5 inches (12 cm) thick.

Lungs: The lungs are a pair of breathing organs located with the chest which remove carbon dioxide from and bring oxygen to the blood. There is a right and left lung.

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.

Pain: An unpleasant sensation that can range from mild, localized discomfort to agony. Pain has both physical and emotional components. The physical part of pain results from nerve stimulation. Pain may be contained to a discrete area, as in an injury, or it can be more diffuse, as in disorders like fibromyalgia. Pain is mediated by specific nerve fibers that carry the pain impulses to the brain where their conscious appreciation may be modified by many factors.

Periodontal: The word "periodontal" literally means "around the tooth." Periodontal diseases are bacterial infections that destroy the attachment fibers and supporting bone that hold the teeth in the mouth. Left untreated, these diseases can lead to tooth loss. The main cause of periodontal disease is a bacterial plaque, a sticky, colorless film that constantly forms on teeth.

Post-nasal drip: Mucous accumulation in the back of the nose and throat leading to or giving the sensation of mucus dripping downward from the back of the nose.

Reflux: The term used when liquid backs up into the esophagus from the stomach.

Respiratory: Having to do with respiration, the exchange of oxygen and carbon dioxide. From the Latin re- (again) + spirare (to breathe) = to breathe again.

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.

Salivary gland: One of the glands in the mouth that produce saliva. There are 3 major salivary glands. They are the parotid, submandibular, and sublingual glands. Each of these glands is paired; there is one parotid gland on each side of the head, etc. The parotid glands are located in front of the ears; the submandibular glands are under the mandible (the lower jaw); and the sublingual glands are under the tongue. Most of the mucosal surfaces within the mouth also contain many minor mucus-secreting salivary glands.

Surgery: The word "surgery" has multiple meanings. It is the branch of medicine concerned with diseases and conditions which require or are amenable to operative procedures. Surgery is the work done by a surgeon. By analogy, the work of an editor wielding his pen as a scalpel is s form of surgery. A surgery in England (and some other countries) is a physician's or dentist's office.

Taste: Taste belongs to our chemical sensing system, or the chemosenses. The complicated process of tasting begins when molecules released by the substances stimulate special cells in the mouth or throat. These special sensory cells transmit messages through nerves to the brain where specific tastes are identified.
See the entire definition of Taste

Throat: The throat is the anterior (front) portion of the neck beginning at the back of the mouth, consisting anatomically of the pharynx and larynx. The throat contains the trachea and a portion of the esophagus.

Tobacco: A South American herb, formally known as Nicotiana tabacum, whose leaves contain 2-8% nicotine and serve as the source of smoking and smokeless tobacco.
See the entire definition of Tobacco

Tongue: The tongue is a strong muscle anchored to the floor of the mouth. It is covered by the lingual membrane which has special areas to detect tastes.

Tonsillitis: Inflammation of the of a tonsil, typically as a result of infection by either a virus or bacteria.

Tonsils: Small masses of lymphoid tissue at the back of the throat, on either side of the throat.

Tooth: The structures within the mouth that allow for biting and chewing. Teeth have different shapes, depending on their purpose. The sharp canine and frontal teeth allow for biting, while the flattened, thick molars in the back of the mouth provide grinding surfaces for masticating food. All teeth have essentially the same structure: a hard crown above the gum line, which is attached to two or four roots by a portion called the neck. The roots are covered with a very thin layer of bone, and keep the tooth embedded in the bones of the jaw. The exposed exterior of the tooth is covered with tough enamel. Under the enamel is a thick layer of dentin, and in the center is the pulp. Blood vessels and nerves are found within the pulp.

Vital: Necessary to maintain life. Breathing is a vital function.

Xerostomia: Dry mouth. The condition of not having enough saliva to keep the mouth wet due to inadequate function of the salivary glands. Everyone has a dry mouth once in a while when they are nervous, upset or under stress. But if someone has a dry mouth all or most of the time, it can be uncomfortable and can lead to serious health problems. Dry mouth can cause difficulties in tasting, chewing, swallowing, and speaking. If it goes untreated, severe dry mouth can also lead to increased levels of tooth decay and infections of the mouth such as thrush.
