Diabetes Mellitus
Syndrome causing altered carbohydrate, protein and fat metabolism, characterized by hyperglycemia
Diabetes Mellitus
Type I
Insulin Dependent Diabetes
Mellitus (IDDM)
Abrupt onset of symptoms
Insulin Dependent
Etiology: autoimmune basis,
genetic predisposition, viral
ONSET: ANYTIME of life
Pathophysiology of Type I DM
Diabetes Mellitus
Type II
Non Insulin Dependent Diabetes (NIDDM)
* More prevalence in adults
Onset at anytime in life
Slow onset
Pathophysiology of DM type 2
Combination of 2 factors:
* Defective insulin secretion by the pancreatic beta cells
* Inability to respond appropriately to the insulin (insulin resistance)
Type II Diabetes Mellitus
Clinical Manifestations:
Polyuria,Polydipsia,Polyphagia
Parathesia and fatigue
Gestational Diabetes
Pregnancy complication in
which women develop chronic hyperglycemia during gestation
Occurs during 2nd/3rd
trimester
Gestational Diabetes
Risk factors:
* Women with a history of
diabetes
* Previous History of stillbirth or spontaneous abortion
* Obesity
* Advanced Maternal age (>35 is considered geriatric
pregnancy)
* 5 or more pregnancies
Diabetes Insipidus
Related to an
insufficiency of ADH
leading to polyuria and
polydipsia
Complications of
Diabetes
Hypoglycemia
Diabetic Ketoacidosis
Hyperosmolar
Hyperglycemia State
Chronic Complications
Diabetic KetoAcidosis
Typically found in patients with Type I Diabetes
Mellitus
Caused by lack of insulin and not allowing the body to use glucose for energy.
Patho of Ketoacidosis
Liver breaks down fat for
fuel- acids called ketones are the end product
Clinical manifestations of DKA
Hyperosmolar
Hyperglycemic State
Characterized by hyperglycemia, hyperosmolarity
with dehydration, the absence of ketoacidosis, and depression of the sensorium
Cortisol
Addisons Disease
Deficiency of glucocorticoids and mineral corticoids
Most commonly caused by autoimmune reactions.
Clinical Manifestations:
of Addisons Disease
Cushing Syndrome
Excessive amounts of glucocorticoids
Caused by pituitary tumor,adrenal cortex tumor or iatrogenic
Clinical manifestations of cushings syndrome
Supressed immune response and atrophy of lymphoid system
Hypertension
Goiter
Enlargement of thyroid gland, caused by thyroid disorders and iodine deficiency
Hyperthyroidism
Excess secretion by the
thyroid gland (clinical
term thyrotoxicosis)
Increased thyroid
hormones effects
Hyperthyroidism- Causes
Graves disease (an autoimmune disorder,most common cause)
Toxic goiter
Thyroid crisis
Hyperthyroidism manifestations
Heat intolerance
Hair loss
Tachycardia
Protruding eyes
Weight loss
