What is Alcoholic Liver Disease (ALD)?
Alcoholic liver disease refers to liver damage caused by chronic and excessive alcohol consumption. It progresses silently from fatty liver (steatosis) to alcoholic hepatitis and finally cirrhosis—often leading to liver failure or cancer if unchecked.
ALD is entirely preventable but often goes undetected until advanced stages. That's why recognizing symptoms early—using a memory aid like DAMP PAGES—can be life-saving.
What Causes Alcoholic Liver Disease?
- Chronic intake of >40g alcohol/day (men) or >20g/day (women) over years
- Binge drinking
- Malnutrition
- Genetic predisposition (e.g., PNPLA3 gene)
- Hepatitis C coinfection
Even moderate alcohol use in genetically vulnerable individuals can lead to liver damage.
Stages of ALD: Steatosis, Hepatitis, Cirrhosis
| Stage | Description | Reversibility |
|---|---|---|
| Fatty liver (steatosis) | Fat accumulation in liver | ✅ Yes |
| Alcoholic hepatitis | Inflammatory liver injury | 🟡 Sometimes |
| Cirrhosis | Permanent scarring of the liver | ❌ No |
Symptoms of ALD: Mnemonic DAMP PAGES
This handy mnemonic helps recall the key signs of alcoholic liver disease:
- D – Discomfort in abdomen
- A – Ascites / Alcohol toxicity
- M – Muscle wasting
- P – Palmer erythema / Portal HTN / Polyneuropathy
- P – Prolonged Prothrombin time
- A – Abdominal pain & low Albumin
- G – Gynaecomastia
- E – Elevated AST and ALT
- S – Spider angiomata
Let’s explore each in detail.
D – Discomfort in Abdomen
- Usually dull, persistent pain in right upper quadrant
- Due to liver enlargement, inflammation, or capsular stretching
- Common in early steatosis and hepatitis
A – Ascites & Alcohol Toxicity
- Ascites: Fluid accumulation in abdomen due to portal hypertension
- Alcohol toxicity: Damages liver cells directly; triggers inflammation
Signs:
- Abdominal distension
- Fluid wave on percussion
- Difficulty breathing (in massive ascites)
M – Muscle Wasting
- Due to malnutrition and catabolic state of liver failure
- Also worsened by hypoalbuminemia
- Appears as thin arms/legs with protuberant abdomen
P – Palmer Erythema, Portal Hypertension, Polyneuropathy
- Palmar erythema: Red palms from estrogen imbalance
- Portal hypertension: High portal venous pressure → varices, splenomegaly
- Polyneuropathy: Nerve damage → numbness, tingling, unsteady gait
P – Prolonged Prothrombin Time
- Reflects liver’s inability to make clotting factors
- Risk of spontaneous bleeding, bruising
- Monitored via INR (International Normalized Ratio)
A – Abdominal Pain & Low Albumin
Low albumin causes:
- Edema
- Ascites
- Poor wound healing
G – Gynaecomastia
Male breast enlargement due to:
- Estrogen buildup
- Hypogonadism (common in cirrhosis)
E – Elevated AST and ALT
Liver enzymes rise due to hepatocyte injury
In ALD:
- AST > ALT
- AST:ALT ratio > 2:1 is classic finding
S – Spider Angiomata
- Small, red, spider-like vascular lesions on skin
- Common on face, upper chest
- Indicator of estrogen excess in liver failure
How ALD is Diagnosed: Labs, Imaging, Biopsy
Blood Tests:
- LFTs (AST, ALT, GGT, ALP)
- Bilirubin
- Albumin, PT/INR
- CBC (macrocytic anemia common)
Imaging:
- Ultrasound: Fatty liver, nodularity
- Fibroscan: Liver stiffness
- CT/MRI for complications
Liver Biopsy:
- Definitive but rarely needed unless diagnosis unclear
Complications of Alcoholic Liver Disease
- Gastroesophageal varices → bleeding
- Hepatic encephalopathy → altered mental status
- Hepatorenal syndrome → kidney failure
- Liver cancer (Hepatocellular carcinoma)
Alcohol Cessation: Why It’s Life-Saving
Stopping alcohol is the single most effective treatment. Benefits include:
- Reversal of fatty liver
- Reduced progression to cirrhosis
- Improved life expectancy
- Lower risk of liver cancer
Tools:
- Support groups (e.g., AA)
- Behavioral therapy
- Medications: Naltrexone, Acamprosate
Treatment and Management of ALD
| Component | Example / Goal |
|---|---|
| Alcohol abstinence | Cornerstone of treatment |
| Nutritional support | High protein, vitamin B1, zinc |
| Medications | Steroids (for alcoholic hepatitis), diuretics (ascites) |
| Infection prevention | Vaccinate for Hep A/B |
| Surveillance | Ultrasound + AFP every 6 months |
Liver Transplant Criteria for ALD
- MELD score > 15
- No alcohol for 6 months minimum (some centers may relax this)
- Psychosocial evaluation for relapse risk
DAMP PAGES Mnemonic Summary Chart
| Letter | Symptom |
|---|---|
| D | Discomfort in abdomen |
| A | Ascites / Alcohol toxicity |
| M | Muscle wasting |
| P | Palmer erythema, Portal HTN |
| P | Prolonged PT |
| A | Abdominal pain, ↓ Albumin |
| G | Gynaecomastia |
| E | Elevated AST, ALT |
| S | Spider angiomata |
Prevention Tips: Nutrition, Vaccines, and Abstinence
- Drink <2 drinks/day (men), <1 (women), ideally none
- Avoid hepatotoxic drugs
- Get vaccinated for Hep A, B
- Maintain healthy BMI
- Regular liver screening if past alcohol history
Final Thoughts and Recap
Alcoholic liver disease progresses silently but dangerously. The DAMP PAGES mnemonic makes clinical features easy to remember and recognize. Early intervention—especially alcohol cessation—can reverse or delay damage.
FAQs on Alcoholic Liver Disease
Q1. Is alcoholic liver disease reversible?
Only the fatty liver stage is reversible. Later stages may be slowed but not fully reversed.
Q2. What is the most important test for ALD?
Liver function tests (AST, ALT), but diagnosis is mainly clinical.
Q3. Can ALD cause liver cancer?
Yes, cirrhosis from ALD significantly raises the risk of hepatocellular carcinoma.
