  1. 1. CHAPTER 11 SUFFIXES: ‘DIPSIA’ AND ‘URIA’<br />PRESENTED BY: YASMIN BUTT<br />
  2. 2. SUFFIX: ‘DIPSIA’<br />THE SUFFIX ‘DIPSIA’ MEANS THIRST<br />IT CAN BE COMBINED WITH ‘POLY’ TO FORM THE TERM ‘POLYDIPSIA’<br />
  3. 3. MEANING OF ‘POLYDIPSIA’<br />‘POLY’ MEANS MANY AND ‘DIPSIA’ MEANS THIRST<br />THE COMBINED TERM MEANS EXCESSIVE THIRST<br />‘POLYDIPSIA’ IS USUALLY AN INITIAL SYMPTOM OF DIABETES <br />IT CAN ALSO OCCUR IF DIABETICS FAIL TO TAKE THEIR MEDICATION OR NEED AN INCREASED DOSAGE<br />
  4. 4. DIABETES AND SUGAR METABOLISM<br />DIABETES IS A CONDITION CAUSED WHEN THE PANCREAS ARE NOT ABLE TO PRODUCE SUFFICIENT INSULIN TO METABOLIZE GLUCOSE IN THE BLOOD<br />AS A RESULT, THE BLOOD GLUCOSE LEVELS ARE ELEVATED AND EXCESS GLUCOSE IS EXCRETED THROUGH LARGE AMOUNTS OF URINE LEADING TO FLUID DEPLETION AND EXCESSIVE THIRST.<br />
  5. 5. OTHER CAUSES OF ‘POLYDIPSIA’<br />CHANGE IN OSMOLALITY OF EXTRACELLULAR BODY FLUIDS<br />HYPOKALEMIA( LOW POTASSIUM LEVELS)<br />CONDITION CAUSING HYPOVOLEMIA SUCH AS HEMORRHAGE<br />

  9. 9. ANOTHER CAUSE OF ‘GLYCOSURIA’<br />ANOTHER LESS COMMON CAUSE IS AN INTINSIC PROBLEM WITH GLUCOSE REABSORPTION IN THE KIDNEYS<br />THIS IS TERMED RENAL GLYCOSURIA<br />THIS IS NOT RELATED TO ELEVATED GLUCOSE LEVELS<br />
