The tuberculosis skin test is based on the fact that infection with M. tuberculosis produces a delayed-type hypersensitivity skin reaction to certain components of the bacterium. The standard recommended tuberculin test is administered by injecting 0.1mL of 5 TU (tuberculin units) PPD into the top layers of skin of the forearm. "Reading" the skin test means detecting a raised, thickened local area of skin reaction, referred to as induration. The area of induration (palpable, raised, hardened area) around the site of injection is the reaction to tuberculin.

A 2017 article in the journal Diabetes Care explains that the goals for dietary change should be “healthful eating patterns emphasizing a variety of nutrient-dense foods in appropriate portion sizes.” Additional goals include achieving a healthy weight; attaining healthy blood sugar, blood pressure, and lipid levels; and reducing complications. The authors emphasize developing an individualized plan based on “personal and cultural preferences, health literacy and numeracy, access to healthful foods, willingness and ability to make behavioral changes, and barriers to change.”
Each month, ASDA issues a Wellness Challenge that asks you to change your behavior in a way that will positively affect your wellness. Each challenge varies in length and activity, but the goal is the same: to get you paying more attention to your well-being and developing good wellness habits. Each challenge will target one (or more) of ASDA’s five dimensions of wellness: emotional, physical, intellectual, occupational and environmental. December's challenge: Brainy expedition. Learn what it takes now.
Diabetes is a disease in which your blood glucose, or blood sugar, levels are too high. Glucose comes from the foods you eat. Insulin is a hormone that helps the glucose get into your cells to give them energy. With type 1 diabetes, your body does not make insulin. With type 2 diabetes, the more common type, your body does not make or use insulin well. Without enough insulin, the glucose stays in your blood. You can also have prediabetes. This means that your blood sugar is higher than normal but not high enough to be called diabetes. Having prediabetes puts you at a higher risk of getting type 2 diabetes.
