Total Bilirubin
Liver Function marker
Bilirubin
Total Bilirubin
Category: Liver Function
Unit: umol/L
Waste product from red blood cell breakdown. Elevated in liver disease or Gilbert's syndrome.
PED Notes
Usually not significantly affected by AAS alone. Elevation alongside elevated liver enzymes suggests more serious liver stress. Gilbert's syndrome (benign) is common and causes chronically mild elevation.
Understanding Bilirubin:
- Mild elevation (20-35 umol/L) with normal liver enzymes → likely Gilbert's syndrome (affects ~5-10% of population, benign)
- Elevation with elevated ALT/AST/GGT → liver stress — address hepatotoxic compounds
- Very high bilirubin (>50 umol/L) with jaundice → urgent medical evaluation required
Supplements:
- NAC -- 600-1200mg/day (supports glutathione and liver detoxification pathways)
- TUDCA -- 500mg/day (if liver-related elevation, improves bile flow)
- Milk Thistle (Silymarin) -- 200-400mg/day (antioxidant liver support)
Lifestyle:
- Stay well hydrated (bilirubin clearance improves with hydration)
- If Gilbert's syndrome: fasting and dehydration worsen elevation — eat before blood draws
- Avoid combining multiple hepatotoxic compounds (oral AAS + alcohol + NSAIDs)
- Monitor trend: stable mild elevation = likely benign; rising trend with enzyme elevation = investigate
