Pruritus

Topical ACV resolves itching relatively quickly. Standard skin-itch treatments may fail because they do not address bile salt deposition in the dermis. When itching is chronic or has no obvious external cause, internal conditions such as liver, gallbladder, kidney, parathyroid, and blood disorders should be investigated. Itching arises when superficial nerve endings in the skin are irritated, and the source can be systemic, metabolic, or neurological rather than topical. Scratching temporarily relieves itching by stimulating the release of serotonin and dopamine. Intense skin itching in liver disease results from disruption of bile salt production and regulation. Intense generalized itching without a rash can result directly from bile duct obstruction. Blocked bile drainage can cause bile salts to accumulate in skin tissue and activate itch receptors. Liver disease pruritus results from bile salts accumulating in systemic circulation and irritating sensory nerves in the skin. The itching from liver-related pruritus has no skin-surface cause; it originates from internal bile salt dysregulation. Bile salts back up into systemic circulation and reach the skin, where they irritate sen…
