What causes glomerulomegaly?

Congenital cyanotic heart disease
Cor pulmonale
Obesity and Sleep apnea
Sickle cell disease
Polycythemia vera
Alcoholism
Hepatic steatosis
Cystic fibrosis

What is the most common physiological abnormality in all of the above

Hypoxemia! Perhaps a combination of metabolic demands of some of these illnesses, hypertrophy of the erythropoietin producing cells, passive congestion causes in the systemic circulation and increased viscosity all might be leading to glomerular damage and proteinuria as a result.

What does glomerulomegaly mean on pathology?

There is going to be focal and diffuse hypercellularity, segmental or global sclerosis, mesangial thickening
Vessels:- capillary congestion, hyalinization of afferent and efferent arterioles
Tubular atrophy
Interstitial Fibrosis
