The consequences of a hyperviscous state may include:
- mucosal bleeding
- visual disturbances - from distension and tortuosity of retinal veins, with narrowing at arteriovenous crossing, producing a segmented "sausage link" pattern; retinal haemorrhage; rarely, papilloedema
- CNS disturbances - vertigo, convulsions, alterations in mental status
- right sided congestive heart failure
- rheological claudication
- proximal renal tubular acidosis or acute renal failure - due to increased excretion of light chains in certain hyperglobulinaemias
