Alcoholic Hepatitis: Causes, Symptoms, and Treatment

Harmful alcohol use causes about 3.3 million deaths each year, making up nearly 6% of all deaths worldwide. Alcoholic hepatitis is a liver disorder that develops when excessive or long-term alcohol consumption causes inflammation. It most often develops in people who drink heavily for many years. Not everyone who drinks heavily develops hepatitis, and the condition can also affect those who consume alcohol in moderation. Your liver is the largest organ in your body. It processes alcohol into various byproducts. These byproducts produce toxins that cause damage to the liver. Liver cells can die and be replaced by scar tissue, which may progress to fibrosis, and eventually cirrhosis or liver cancer.

Causes

Alcoholic hepatitis is mainly caused by heavy drinking over time. As the liver processes alcohol, it produces toxins that harm liver cells and trigger inflammation. The immune system attempts to fix the damage, but this response can sometimes worsen the inflammation.

Alcohol can also weaken the gut lining, allowing bacteria and toxins to enter the liver and increase injury. Over time, fat builds up in the liver, and damaged areas may form scar tissue (fibrosis). If scarring becomes severe, it leads to cirrhosis, which is permanent.

Certain factors can increase the risk or make the condition worse, such as:

• Other liver diseases (like hepatitis C)
• Poor nutrition
• Genetics
• Obesity
• Being female

In rare cases, some medicines or toxins can also damage the liver, but alcoholic hepatitis is specifically caused by alcohol use.

Symptoms

• Jaundice – yellow eyes and skin
• Poor appetite
• Fever
• Fatigue
• Nausea, vomiting
• Swelling over the legs and abdomen
• Confusion, drowsiness
• Anxiety, tremors

Risk Factors

Alcohol does not affect every person in the same way. People who drink heavily may never develop the condition, while people who drink occasionally may develop it. Heavy episodic drinking is defined as consumption of more than 60 g of pure alcohol on one occasion, and generally, people who binge drink, which is defined as men who have five or more drinks and women who have four or more drinks within a few hours, are at risk of damaging their liver.

Treatment Options

The first step is to quit drinking. If your liver damage is minimal, it will likely reverse the damage. The treatment plan includes the following.

• Steroids are used to reduce swelling of the liver after confirmation of the diagnosis through liver biopsy.
• Antibiotics to fight bacterial infections, if any
• Diet change, with a high protein diet to +/- a low-sodium diet
• Diuretics may be used to reduce water retention if kidney function tests are standard.
• Vitamin supplements to boost the immune system.

If the damage is extensive and treatment is not effective, your liver may go into failure and may require a liver transplant.

Complications

Alcoholic hepatitis can cause serious health problems, especially when the liver becomes scarred or turns into cirrhosis. Common complications include:

• Ascites: Fluid buildup in the belly that can get infected.
• Cirrhosis and liver failure: Permanent scarring stops the liver from working.
• Hepatic encephalopathy: Toxins affect the brain, causing confusion, sleepiness, or coma.
• Infections: A weakened immune system raises the risk of severe infections.
• Kidney failure (hepatorenal syndrome): Reduced blood flow to the kidneys leads to organ failure.
• Liver cancer: Long-term liver damage raises cancer risk.
• Malnutrition: Poor diet and a weak liver reduce nutrient absorption.
• Varices and internal bleeding: Swollen veins in the esophagus or stomach may burst and cause life-threatening bleeding.
• Death: Severe cases have a high risk of death, especially with complications.

When to Seek Immediate Medical Attention?

If you have alcoholic hepatitis and suddenly develop any of the symptoms, rush to the hospital.

• Sever jaundice
• Mental confusion
• Pass the black tarry stool
• Vomit blood
• Fever with chills
• Fluid buildup in the abdomen

Prevention

You can lower the risk of alcoholic hepatitis by making healthy choices:

1. Limit or avoid alcohol

The safest choice is to completely avoid alcohol. If you choose to drink, do so in moderation. Even moderate drinking can sometimes harm the liver, so be careful and know your limits.

2. Get tested for hepatitis C

Hepatitis C can damage the liver and increase the risk of cirrhosis. Adults should get screened, and if you have hepatitis C, avoid alcohol completely.

3. Be careful with medicines

Some medicines, like acetaminophen (Tylenol), can be harmful to the liver, especially when combined with alcohol. Always read labels and ask your doctor or pharmacist before mixing medicines with alcohol.

4. Talk to your healthcare provider

If you already have liver problems or a history of heavy drinking, speak with your doctor before taking any over-the-counter or prescription medicines.

By limiting alcohol, protecting your liver, and using medicines safely, you can greatly reduce the risk of alcoholic hepatitis.
