Drug allergies are a group of symptoms caused by allergic reaction to a drug (medication).
|
|
|
Drug interactions are changes in the effect of one drug due to the effect of either another drug taken at the same time (drug-drug interactions) or food consumed while the drug is being taken (drug-food interactions). Some drugs are deliberately combined for administration because there are beneficial effects to be derived.
|
|
A drug allergy is an adverse reaction to a medication, often an antibiotic, that is mediated by the body ' s immune system. A drug sensitivity is an unusual reaction to a drug that does not involve the immune system.
|
|
Drug metabolism is the process by which the body breaks down and converts medication into active chemical substances. Precautions Drugs can interact with other drugs, foods, and beverages.

AIDS (Acquired Immune Deficiency Syndrome) is the final and most serious stage of HIV disease , which causes severe damage to the immune system. According to the Centers for Disease Control and Prevention, AIDS begins when a person with HIV infection has a CD4 cell count below 200. (CD4 is also called "T-cell", a type of immune cell.) AIDS is also defined by numerous opportunistic infections and cancers that occur in the presence of HIV infection.

Acquired immunodeficiency syndrome, or AIDS, is the final, life-threatening stage of infection with any of the human immunodeficiency viruses (HIV-1, its many subtypes, or HIV-2), which are transmitted from person to person sexually (including via anal, oral, and vaginal intercourse, both heterosexually and homosexually), through contact with blood (mainly via equipment used to inject illicit drugs and, rarely, via medical uses of blood), and perinatally (from mother to fetus or newborn during pregnancy, labor, and delivery, or after birth through breast-feeding). ORIGIN AND HISTORY HIV-1 and HIV-2 both appear to have been transmitted to humans from primates in Central and West Africa, probably to hunters or processors of carcasses of primates consumed as food (referred to as " bush meat " ).

HIV (human immunodeficiency virus) was identified in 1983 by the French scientist Luc Montagier and his staff at the Pasteur Institute in Paris. Ever since that discovery, scientists have been searching for ways to treat those infected with HIV, and to produce a vaccine to prevent its spread.

Diabetes is a life-long disease marked by high levels of sugar in the blood. It can be caused by too little insulin (a hormone produced by the pancreas to regulate blood sugar), resistance to insulin, or both.
|
|
|
If you have diabetes, you are two to four times more likely to have heart disease than someone without diabetes. You can control your health risks by making some changes in your life.

Carbohydrates are your body’s main source of glucose, a special kind of sugar. Your dietitian will probably recommend that 55 to 60 percent of your calories come from carbohydrates. There are two types of carbohydrates: complex and simple.
|
|
Type 1 diabetes can be controlled by taking insulin, eating a proper diet, and being active. These help your child’s body keep healthy blood sugar levels.

Diabetes mellitus is a common metabolic disorder resulting from defects in insulin action, insulin production, or both. Insulin, a hormone secreted by the pancreas, helps the body use and store glucose produced during the digestion of food.
|
|
|
Diabetes mellitus is a condition that occurs when either the pancreas does not produce enough insulin or the body ' s cells stop responding to the insulin that is produced. In either case, glucose in the blood cannot be absorbed or used by the cells of the body.

|
|
Diabetes is the Greek term for " passing through, " a phrase used to describe multiple diseases characterized by excessive urination. There are multiple forms of diabetes.
|
|
|
Diabetes mellitus is a chronic disease in which the body is not able to correctly process glucose for cell energy due to either an insufficient amount of the hormone insulin or a physical resistance to the insulin the body does produce. Without proper treatment through medication and/or lifestyle changes, the high blood glucose (or blood sugar) levels caused by diabetes can cause long-term damage to organ systems throughout the body.
|
|
A serious disorder caused by an absence of or insufficient amount of insulin in the bloodstream. Insulin is a hormone produced by the pancreas in varying amounts, depending on the concentration of glucose (sugar).
|
|
|
Diabetes mellitus describes a group of diseases in which there is an elevated level of the sugar glucose, the body's main source of energy for cellular functions, in the blood. The level of glucose, as well as other "fuel" molecules, is increased due to a disorder in the production or function of the hormone insulin.

Guillain-Barre syndrome is a serious disorder that occurs when the body's defense (immune) system mistakenly attacks part of the nervous system. This leads to nerve inflammation that causes muscle weakness , which continues to get worse.
|

Guillain-Barr e syndrome (GBS) causes progressive muscle weakness and paralysis (the complete inability to use a particular muscle or muscle group), which develops over days or up to four weeks, and lasts several weeks or even months. The classic scenario in GBS involves a patient who has just recovered from a typical, seemingly uncomplicated viral infection.
|
|
Guillain-Barr e syndrome (GBS) is an inflammation of the covering that surrounds nerve cells of the brain and spinal cord. The basis of the inflammation is not conclusively known, but is generally considered to arise from a malfunctioning immune system that recognizes host tissues as being foreign.
