Predisposing factor: Precipitating factor:

Age Activities Increase Glucose in the Blood

Sex Genetic

Lifestyle Diet

Extracellular hyperglycemia

Loss of uid from plasma through osmosis Blood glucose reach renal threshold

Plasma !ecomes hyperosmotic Blood "ltered !y nephrons

Shift of uid from the interstitial uid to plasma Blood o#s to arteriole

Increase interstitial uid osmolality Glomerulus

$luid moves from intracellular to the extracellular uid $iltrate #as produces includingglucose

Decrease in E%$ and I%$ volume $iltrate passes through the proximal tu!ule

Increase in osmolality of E%$ and I%$

Glucose is rea!sor!ed from the "ltrate across the

tu!ular epithelium into the !loodstream

Dehydration of cell

Glucose level exceeds a!out &'()&*( mg+dl, proximal tu!ule

Begins to excrete glucose in the urine

Glucosuria

-smotic diuresis Glucose cause additional #ater to come into urine

Increase urine output

Potassium Needed for proper fluid balance, nervetransmission, and muscle contraction

Calcium Important for healthy bones and teeth; helpsmuscles relax and contract; important innerve functioning, blood clotting, bloodpressure regulation, immune system health

Milk and milk products; canned fish

(broccoli, mustard greens); legumes

Phosphorus Important for healthy bones and teeth;found in every cell; part of the system that

maintains acidbase balance

Bicar!onate is a maor element in our !ody6 Secreted !y the

stomach, it is necessary for digestion6 9hen ingested, for

example, #ith mineral #ater, it helps !u8er lactic acid generated

during exercise and also reduces the acidity of dietarycomponents6 $inally, it has a prevention e8ect on dental cavities6
