How do the liver and LFTs change during pregnancy?

• A. Liver size increases; blood flow decreases; fibrinogen decreases; albumin increases; metabolic enzymes speed up
• B. Liver size does not change; blood flow increases; fibrinogen increases 50%; plasma albumin decreases; enzymatic processes can slow down delaying drug metabolism
• C. Liver enlarges with increased metabolism; LFTs decrease
• D. Liver shrinkage; bilirubin increases

Answer: (B)

During pregnancy the liver doesn’t usually enlarge; what changes are largely hemodynamic and synthetic. Hepatic blood flow increases to support the greater metabolic demands of both mother and fetus. At the same time the liver increases production of coagulation factors, so fibrinogen rises—about a 50% increase is typical—helping create the hypercoagulable state of pregnancy. Plasma albumin, the main protein in blood, decreases due to hemodilution, which can affect colloid osmotic pressure and drug binding. LFTs themselves are not expected to consistently drop; they usually remain within normal limits, though drug-metabolizing activity can be altered. Some enzymes and pathways may slow down for certain drugs, leading to changes in drug metabolism. Taken together, this description matches the physiological pattern of increased blood flow and coagulation factor production with lowered albumin, rather than changes in liver size or straightforward decreases in enzyme activity across the board.
