General

Major cardiovascular risk factor.
Many subtypes.
- Most common: DM type 2 -- strongly associated with obesity.

Diagnosis

Based on biochemistry, specifically:

Fasting blood glucose >=7.0 mmol/L.
Two-hour glucose tolerance test >=11.1 mmol/L.

Classic complications

Family medicine - mnemonic HELP:

H - HbA1c, hypertension.
E - eye.
L - lipids.
P - podiatry, proteinuria, Pneumococcus vaccine.

Emergency room presentations

Ketoacidosis - DM type 1.
Hyperosmotic non-ketotic (HONK) coma - DM type 2.

Subspecialty specific findings

Dermatopathology

Other:

Fibroepithelial polyp.

Gastrointestinal pathology

Microscopic colitis - generally assoc. with autoimmune disorders.
Pancreatic amyloid deposition - in DM type 2.^[1]
Centrilobular macrovescicular steatosis of the liver.
Pancreatic islet cell hyperplasia - in the fetus of a mother with diabetes.

Breast pathology

Diabetic mastopathy.

Genitourinary pathology

Placental pathology

Cardiovascular pathology

Atherosclerosis.
Arterial hyaline - in both afferent and efferent arteriole of the kidney.

Neuropathology

Idiopathic inflammatory myositis.^[4]

Forensic pathology

Diabetic coma (preceding death) at autopsy - may be demonstrated with an elevated glucose in the vitreous fluid.^[5]
