Question 47:
A decrease in the concentration of serum albumin leads to which of the following conditions?
The correct answer is (A) Chronic liver disease.
A decrease in serum albumin concentration, known as hypoalbuminemia, directly results from impaired liver synthesis, as the liver produces nearly all of the body’s albumin.
Option Breakdown
(A) Chronic Liver Disease
Chronic liver diseases like hepatitis or fatty liver damage hepatocytes, reducing albumin production and causing low serum levels (typically <3.5 g/dL). This leads to edema due to decreased oncotic pressure.
(B) Hemochromatosis
This iron overload disorder causes liver damage and fibrosis, but hypoalbuminemia occurs only in advanced stages as a secondary effect, not the primary condition.
(C) Wilson Disease
A genetic copper accumulation disorder affecting the liver, it can lower albumin in cirrhosis stages, but the decrease stems from end-stage liver failure, not the disease itself.
(D) Cirrhosis
Cirrhosis, an end-stage scarring of the liver from chronic damage, features low albumin due to synthetic failure, but it’s a specific outcome rather than the broad category of chronic liver disease.
Introduction to Decrease Serum Albumin Concentration
A decrease serum albumin concentration below 3.5 g/dL often indicates chronic liver issues, where reduced hepatic synthesis disrupts fluid balance. Essential for GATE Life Sciences prep, it differentiates from metal storage disorders.
Causes of Low Serum Albumin
Liver impairment from chronic inflammation halts albumin production, while losses via kidneys or gut contribute less commonly. Symptoms include swelling and fatigue from low oncotic pressure.
Normal levels range 3.5-5.0 g/dL; chronic drops signal progression.
Conditions Comparison Table
| Condition | Primary Mechanism | Albumin Decrease Role | Key Feature |
|---|---|---|---|
| Chronic Liver Disease | Impaired synthesis | Direct cause | Hepatitis, fatty liver |
| Hemochromatosis | Iron overload damage | Secondary in late stages | Bronze diabetes |
| Wilson Disease | Copper buildup | Late liver failure | Kayser-Fleischer rings |
| Cirrhosis | Scarring/synthetic failure | End-stage result | Ascites, varices |
This clarifies decrease serum albumin concentration for competitive exams.
Implications for Life Sciences Students
Recognizing low albumin as a chronic liver disease marker sharpens biochemistry and pathology knowledge, aiding PYQ solving in exams.
