Liver failure edema often flares at what time of day?

• A. Midday and Midnight
• B. Morning
• C. Evening
• D. Afternoon

Answer: (A)

In liver failure, edema comes from low albumin levels lowering the blood’s ability to hold fluid in the vessels, combined with portal hypertension pushing fluid into interstitial spaces. Fluid balance in the body also changes over the day with posture and circadian hormone patterns, so swelling isn’t constant but tends to appear more at certain times. When you’re upright and active, gravity shifts fluid into the legs and other dependent areas, making edema more noticeable around the middle of the day. Later, during recumbency at night, fluid can redistribute and hormonal factors that promote water retention can further contribute to edema, so swelling can flare again then. So saying that edema often shows up around midday and again at night aligns with how posture and circadian fluid regulation influence edema in liver failure.
