The excess immunoglobulins increase the thickness (viscosity) of the blood and cause it to move slowly through the blood vessels. Hyperviscosity syndrome limits blood flow to the skin, fingers, toes, nose, and brain. The blood vessels become overfilled with blood and may leak, causing discoloration of the skin.
diÂ·alÂ·yÂ·sis. Use dialysis in a sentence. pl. -Â·sesÂ·. Chem. any process in which the smaller dissolved molecules in a solution separate from the larger molecules by diffusing through a semipermeable membrane.
Dialysis is the artificial process of eliminating waste (diffusion) and unwanted water (ultrafiltration) from the blood. Our kidneys do this naturally. Some people, however, may have failed or damaged kidneys which cannot carry out the function properly-they may need dialysis.eople whose kidneys either do not work properly or not at all experience a buildup of waste in their blood. Without dialysis the amount of waste products in the blood would increase and eventually reach levels that would cause coma and death. Dialysis is also used to rapidly remove toxins or drugs from the blood.
