Defining characteristics include increase level of sugar in the blood and high concentration of ketones in body fluids. The signs and symptoms are vomiting excessive loss of body fluid‚ decrease in the level of consciousness and sometimes rapid breathing pattern. One of the provoking factors is noncompliance to insulin therapy in diagnosed patients. Diabetic ketoacidosis

condition back to its normal state; this is the most common way that the body regulates itself. Examples of negative feedback: (1) when blood pressure rises‚ the heart slows down; (2) when glucose levels in the blood are too high‚ the pancreas secretes insulin to stimulate the absorption of glucose and the conversion of glucose into glycogen. In positive feedback‚ the body reacts to a change from the normal state by causing an even greater change. Examples of positive feedback: (1) when constrictions in

treatment options‚ this disease is controllable and in some cases‚ may even be prevented. Diabetes and who it Affects Most Diabetes mellitus (DM)‚ more commonly known as diabetes‚ is the result of insufficient insulin production or the body’s inability to respond to insulin (Forth & Jude‚ 2011). Diabetes is a disease that affects how the body uses blood glucose‚ or blood sugar. Blood glucose is vital to health because it is an essential source of energy for cells of the muscles and
Premium Blood sugar Diabetes mellitus Insulin
Diabetes mellitus is a disorder in which blood levels of glucose are abnormally high because the body does not release or use insulin adequately (Merck 1999‚ p.788). There are two types of diabetes mellitus‚ which are type 1 diabetes and type 2 diabetes. A hormone called insulin‚ released by the pancreas‚ is the primary substance responsible for maintaining appropriate blood sugar levels. Blood sugar levels vary throughout the day‚ rising after a meal and returning to normal within two hours. Blood

levels of blood acids called ketones. Diabetic ketoacidosis develops when your body is unable to produce enough insulin and an increase in insulin counter-regulatory hormones (catecholamines‚ cortisol‚ glucagon and growth hormone). Insulin normally plays a key role in helping sugar (glucose) — a major source of energy for your muscles and other tissues — enter your cells. Without enough insulin‚ your body begins to break down fat as an alternate fuel. This process produces a build-up of toxic acids in
