CLINICAL FEATURES
and complications
OfDiabetes Mellitus
Vajja Swathi8th Sem
Diabetes mellitus is a metabolic disorder characterized by chronic hyperglycemia with disturbances in metabolism of
Carbohydrates, Fats ,Proteins
resulting from defects ofInsulin secretion, Insulin action (or)Both

Type I Diabetes:
Have little or no insulin secretory capacity.
Depend on exogenous insulin to prevent metabolic decompensation and death.
Symptoms are ACUTE and appear relatively abruptly (i.e. Over days or Weeks)

Complications
Clinical presentation of Diabetes is heterogeneous ranging from asymptomatic type to life threatening diabetic ketoacidosis.
TYPE I DIABETESOSMOTIC SYMPTOMS :
Thirst and frequent drinking (POLYDIPSIA)
More frequent urination, (POLYURIA)
Excessive hunger (POLYPHAGIA)
Unexplained weight loss
Fatigue and Lassitude
ASSOCIATED SYMPTOMS:Muscular Cramps
Blurred vision
Cutaneous and Oro genital fungal or bacterial infections.

Complications
Type II Diabetes:Insulin resistance
Body tissues do not respond to insulin Results in hyperglycemia
Decreased (but not absent) endogenous insulin secretory capacity. Not dependent on insulin
for immediate survival
Require insulin therapy for optimal glycemic control over time
Clinical features of type 2 diabetes can be insidious
TYPE II DIABETESASYMPTOMATIC
Undetected hyperglycemia for many years (asymptomatic phase)
OSMOTIC SYMPTOMS :
Classic symptoms may be quite mild
Thirst and frequent drinking (POLYDIPSIA)
More frequent urination (POLYURIA), Nocturia
Excessive hunger (POLYPHAGIA)
Weight Gain

Develops during pregnancy.
Detected at 24 to 28 weeks of gestation.
