3. Glycosuria• Glycosuria, or glucosuria, is the excretion of glucose into urine.• In a normal functioning body the kidneys reabsorb all of the glucose and re-integrate it into the bloodstream.• This condition is primarily caused by elevated blood glucose levels which, in turn, is primarily caused by diabetes mellitus.
4. Glycosuria caused by Diabetes Mellitus• Diabetes mellitus is a condition where the pancreas cannot produce a sufficient amount of insulin to counter the glucose in the body. This condition may cause an over abundance of sugar in the bloodstream which then becomes too much for the kidneys to filter out.
5. Excessive thirst: Polydipsia
6. Polydipsia• Excessive thirst is a common symptom of a diabetes insipidus and diabetes mellitus• In diabetes insipidus excessive urination takes place causing excessive dehydration. The hormone ADH is very low, in response very diluted urine is produced causing the person feeling very thirsty.• In diabetes mellitus, if untreated, causes a higher level of glucose in the urine, which then leads to large urine volumes, which then causes the affected person to have a near unquenchable thirst.
7. Polydipsia in the Endocrine System• Diabetes is caused by not having proper balance of glucose in your system. The pancreas produces two hormones called insulin and glucagon.• Insulin lowers glucose levels, glucagon raises glucose levels.• When the balance between glucose and insulin is out of whack it can lead to diabetes, which as seen in prior slides leads to polydipsia, or excessive thirst.
