Prevention

Washing the hands frequently can help to prevent strep throat.

Exposure to infected people should also be avoided. In order to prevent transmission of the disease within households, consult a doctor if any family member suddenly develops a sore throat (especially if it is accompanied by fever).

Boosting the immune system is also important to help prevent the development of strep throat. Vitamin C and zinc are often recommended for this purpose, as are goldenseal, echinacea, and garlic.

Definition

Stress is an individual’s physical and mental reaction to environmental demands or pressures.

Description

When stress was first studied, the term was used to denote both the causes and the experienced effects of these pressures. More recently, however, the word stressor has been used for the stimulus that provokes a stress response. One recurrent disagreement among researchers concerns the definition of stress in humans. Is it primarily an external response that can be measured by changes in glandular secretions, skin reactions, and other physical functions, or is it an internal interpretation of, or reaction to, a stressor; or is it both?

Definition

Probiotics, as defined by the Food and Agricultural Organization of the United Nations (FAO), are “live microorganisms administered in adequate amounts which confer a beneficial health effect on the host.” The microorganisms referred to in this definition are non-pathogenic bacteria (small, single celled organisms which do not promote or cause disease), and one yeast, Saccharomyces.

Definition

Psoriasis is a chronic, non-contagious disease characterized by inflamed hyperproliferative lesions covered with silvery-white scabs of dead skin.

Description

Psoriasis, which affects at least four million Americans, is slightly more common in women than in men. Although the disease can develop at any time, 10–15% of all cases are diagnosed in children under 10, and the average age at the onset of symptoms is 28 years of age. Psoriasis is most common in fair-skinned people and relatively rare in dark-skinned individuals, although the rate among African Americans appears to be slowly rising.

Definition

Diverticulitis refers to the development of inflammation and infection in one or more diverticula. Diverticula are outpouchings or bulges which occur when the inner, lining layer of the large intestine (colon) bulges out (herniates) through the outer, muscular layer. The presence of diverticula indicates a condition called diverticulosis.
