The following are health and medical definitions of terms that appear in the multivitamins (includes prenatal vitamins)-effervescent tablets article.
Absorption: Uptake. For example, intestinal absorption is the uptake of food (or other substances) from the digestive tract.
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.
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.
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.
Nursing: 1) Profession concerned with the provision of services essential to the maintenance and restoration of health by attending the needs of sick persons. 2) Feeding a infant at the breast.
Nutrition: 1) The science or practice of taking in and utilizing foods. 2) A nourishing substance, such as nutritional solutions delivered to hospitalized patients via an IV or IG tube.
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.
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.
Pregnant: The state of carrying a developing fetus within the body.
Prenatal: Occurring or existing before birth.
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.
Stomach: The digestive organ that is located in the upper abdomen, under the ribs. The upper part of the stomach connects to the esophagus, and the lower part leads into the small intestine. When food enters the stomach, muscles in the stomach wall create a rippling motion (peristalsis) that mixes and mashes the food. At the same time, juices made by glands in the lining of the stomach help digest the food. After about 3 hours, the food becomes a liquid and moves into the small intestine, where digestion continues.
Taste: A perception that results from stimulation of a gustatory nerve. Taste belongs to the chemical sensing system. Tasting begins when molecules stimulate special cells in the mouth or throat. These special cells transmit messages through nerves to the brain, where specific tastes are identified. Gustatory, or taste, cells react to food and beverages. The taste cells are clustered in the taste buds of the mouth and throat. Many of the small bumps that can be seen on the tongue contain taste buds. Smell contributes to the sense of taste, as does another chemosensory mechanism, called the common chemical sense. In this system, thousands of nerve endings'especially on the moist surfaces of the eyes, nose, mouth, and throat'give rise to sensations such as the sting of ammonia, the coolness of menthol, and the irritation of chili peppers. People can commonly identify four basic taste sensations: sweet, sour, bitter, and salty. In the mouth, these tastes, along with texture, temperature, and the sensations from the common chemical sense, combine with odors to produce the perception of flavor. Flavors are recognized mainly through the sense of smell. If a person holds his or her nose while eating chocolate, for example, the person will have trouble identifying the chocolate flavor'even though he or she can distinguish the food's sweetness or bitterness. That is because the familiar flavor of chocolate is sensed largely by odor.
Vitamins: The word "vitamin" was coined in 1911 by the Warsaw-born biochemist Casimir Funk (1884-1967). At the Lister Institute in London, Funk isolated a substance that prevented nerve inflammation (neuritis) in chickens raised on a diet deficient in that substance. He named the substance "vitamine" because he believed it was necessary to life and it was a chemical amine. The "e" at the end was later removed when it was recognized that vitamins need not be amines.
