Anxiety: Apprehension of danger, or dread, accompanied by nervous restlessness, tension, increased heart rate, and shortness of breath unrelated to a clearly identifiable stimulus.
Autoimmune Disease: One of a large group of diseases in which the immune system turns against the body's own cells, tissues and organs, leading to chronic and often deadly conditions. Examples include multiple sclerosis, rheumatoid arthritis, systemic lupus, Bright's disease and diabetes.
Candidiasis: Infection of the skin or mucous membrane with any species of candida, usually Candida albicans. The infection is usually localized to the skin, nails, mouth, vagina, bronchi, or lungs, but may invade the bloodstream. It is a common inhabitant of the GI tract, only becoming a problem when it multiplies excessively and invades local tissues. Growth is encouraged by a weakened immune system, as in AIDS, or with the prolonged administration of antibiotics. Vaginal symptoms include itching in the genital area, pain when urinating, and a thick odorless vaginal discharge.
Dopamine: A neurohormone; precursor to norepinephrine which acts as a stimulant to the nervous system.
Enzymes: Specific protein catalysts produced by the cells that are crucial in chemical reactions and in building up or synthesizing most compounds in the body. Each enzyme performs a specific function without itself being consumed. For example, the digestive enzyme amylase acts on carbohydrates in foods to break them down.
Estrogen: One of the female sex hormones produced by the ovaries.
Glucose: A sugar that is the simplest form of carbohydrate. It is commonly referred to as blood sugar. The body breaks down carbohydrates in foods into glucose, which serves as the primary fuel for the muscles and the brain.
Hormones: Chemical substances secreted by a variety of body organs that are carried by the bloodstream and usually influence cells some distance from the source of production. Hormones signal certain enzymes to perform their functions and, in this way, regulate such body functions as blood sugar levels, insulin levels, the menstrual cycle, and growth. These can be prescription, over-the-counter, synthetic or natural agents. Examples include adrenal hormones such as corticosteroids and aldosterone; glucagon, growth hormone, insulin, testosterone, estrogens, progestins, progesterone, DHEA, melatonin, and thyroid hormones such as thyroxine and calcitonin.
Hypothalamus: An important supervisory center in the brain regulating many body functions. Despite its importance in maintaining homeostasis, the hypothalamus in humans accounts for only 1/300 of total brain weight, and is about the size of an almond.
MAO: Abbreviation for a breakdown enzyme monoamine oxidase. A MAO inhibitor blocks the action of monoamine oxidase, thus raising the levels of the monoamine neurotransmitters such as norepinephrine, epinephrine, dopamine, and serotonin - which have significant effects on mood and behavior. Epinephrine, norepinephrine and serotonin are normally deactivated by MAO-A while dopamine and phenylethylamine are normally metabolized by MAO-B.
Noradrenaline: (Norepinephrine): A catecholamine hormone secreted from the adrenal medulla and post-ganglionic adrenergic fibers in response to hypotension or emotional stress.
Premenstrual Syndrome: PMS consists of various physical and/or emotional symptoms that occur in the second half of the menstrual cycle, after ovulation. The symptoms begin about midcycle, are generally the most intense during the last seven days before menstruation and include: acne; backache; bloating; fatigue; headache; sore breasts; changes in sexual desire; depression; difficulty concentrating; difficulty handling stress; irritability; tearfulness.
Serotonin: A phenolic amine neurotransmitter (C10H12N2O) that is a powerful vasoconstrictor and is found especially in the brain, blood serum and gastric membranes of mammals. Considered essential for relaxation, sleep, and concentration.
Serum: The cell-free fluid of the bloodstream. It appears in a test tube after the blood clots and is often used in expressions relating to the levels of certain compounds in the blood stream.
Tryptophan: Essential amino acid. Natural relaxant and sleep aid due to its precursor role in serotonin (a neurotransmitter) synthesis. Along with tyrosine, it is used in the treatment of addictions.
Yeast: A single-cell organism that may cause infection in the mouth, vagina, gastrointestinal tract, and any or all bodily parts. Common yeast infections include candidiasis and thrush.
