Chronic Liver Disease (Cirrhosis)
What is Chronic Liver Disease (Cirrhosis)?
Chronic liver disease is ongoing damage to your liver that happens over months or years. Your liver is a vital organ that filters toxins, stores nutrients, and makes proteins your body needs. When it's injured repeatedly, scar tissue builds up and replaces healthy tissue. This scarring is called fibrosis.
Cirrhosis is the advanced stage of chronic liver disease. At this point, extensive scar tissue has replaced most healthy liver cells. The scarring is permanent and makes it hard for your liver to do its job. Your liver can still function for a while, but over time it may fail completely.
The good news is that liver disease often develops slowly. Catching it early gives you time to slow or stop the damage. Blood tests can reveal early warning signs before you feel sick. Understanding your risk and getting tested regularly helps you protect your liver before serious damage occurs.
Symptoms
- Fatigue and weakness that doesn't improve with rest
- Easy bruising or bleeding
- Yellowing of skin and eyes, called jaundice
- Swelling in legs, ankles, or abdomen
- Itchy skin
- Dark urine
- Pale or tar-colored stools
- Nausea and loss of appetite
- Confusion or difficulty concentrating
- Spider-like blood vessels on the skin
Many people have no symptoms in the early stages of liver disease. Your liver can lose significant function before you notice anything wrong. This is why regular blood testing is so important, especially if you have risk factors.

Causes and risk factors
The most common causes of chronic liver disease include heavy alcohol use, viral hepatitis, and fatty liver disease. Alcohol damages liver cells directly and causes inflammation over time. Hepatitis B and hepatitis C are viral infections that attack the liver. Nonalcoholic fatty liver disease happens when too much fat builds up in the liver, often linked to obesity, diabetes, and metabolic syndrome.
Other risk factors include certain medications, autoimmune conditions where your immune system attacks the liver, and inherited diseases like hemochromatosis or Wilson disease. Poor nutrition, especially folate deficiency, can worsen liver damage. Some people develop liver disease from a combination of factors. The more risk factors you have, the more important it is to monitor your liver health with regular testing.
How it's diagnosed
Doctors diagnose chronic liver disease using blood tests, imaging studies, and sometimes liver biopsy. Blood tests measure liver enzymes, protein levels, and other markers that show how well your liver is working. Mean Corpuscular Volume, or MCV, measures the size of your red blood cells. Elevated MCV can indicate liver disease because liver damage affects how your body makes red blood cells and stores folate.
Rite Aid offers testing that includes MCV as part of our flagship panel. Our test uses Quest Diagnostics locations nationwide, making it easy to check for early signs of liver problems. Regular testing helps you catch changes before they become serious. If your results show concerning patterns, your doctor may order additional imaging or specialized tests to confirm the diagnosis and stage of liver disease.
Treatment options
- Stop drinking alcohol completely if alcohol contributed to liver damage
- Lose weight through balanced nutrition and regular physical activity if you have fatty liver disease
- Treat underlying conditions like hepatitis with antiviral medications
- Eat a nutrient-rich diet with adequate protein, vitamins, and minerals
- Avoid medications and supplements that can harm the liver
- Get vaccinated against hepatitis A and B if you haven't already
- Manage complications with medications for fluid retention, bleeding risk, or confusion
- Consider liver transplant evaluation if cirrhosis becomes severe
Treatment focuses on stopping further damage and managing symptoms. Many people can slow or halt disease progression with lifestyle changes. Work closely with your doctor to monitor your liver function and adjust treatment as needed. Early intervention gives you the best chance to preserve your liver health.

Frequently asked questions
Chronic liver disease is any ongoing liver damage that lasts months or years. Cirrhosis is the advanced stage where extensive scarring has replaced healthy liver tissue. Not all chronic liver disease progresses to cirrhosis, especially if caught and treated early. Cirrhosis represents irreversible damage, while earlier stages may still be reversible.
You cannot fully reverse cirrhosis because the scarring is permanent. However, you can stop it from getting worse and sometimes improve liver function. Treating the underlying cause, like quitting alcohol or losing weight, can prevent further damage. In some cases, early-stage fibrosis can improve, but advanced cirrhosis requires ongoing management.
Alcohol breaks down into toxic substances that damage liver cells and cause inflammation. Over time, repeated injury leads to scarring. Your liver can regenerate, but constant alcohol use doesn't give it time to heal. The amount and duration of drinking both affect your risk, with heavy daily use causing the most damage.
Elevated MCV means your red blood cells are larger than normal. This can happen with liver disease because liver damage affects how your body makes red blood cells and stores folate. It also reflects changes in cell membrane composition from altered fat metabolism. High MCV is one clue that prompts doctors to look more closely at liver function.
If you have risk factors like heavy alcohol use, obesity, diabetes, or viral hepatitis, get tested at least once a year. Some doctors recommend testing every six months if you already have liver damage. Regular monitoring helps catch changes early. Your doctor can recommend a testing schedule based on your specific situation.
Fatty liver disease happens when fat builds up in your liver even if you drink little or no alcohol. It's called nonalcoholic fatty liver disease and is linked to obesity, diabetes, and metabolic issues. Alcoholic liver disease comes from heavy alcohol use. Both can cause similar damage and progression to cirrhosis, but they have different root causes and treatments.
Focus on vegetables, fruits, whole grains, lean proteins, and healthy fats like those in fish and nuts. Foods rich in antioxidants and fiber support liver function. Limit processed foods, added sugars, and saturated fats. Coffee has been shown to protect the liver in some studies. Staying hydrated and maintaining a healthy weight also help your liver work properly.
Yes, liver disease can cause both weight loss and weight gain. You might lose muscle mass and appetite as liver function declines. However, fluid retention from cirrhosis can cause your abdomen and legs to swell, making you appear to gain weight. Your actual body weight might drop even as fluid accumulates.
See a doctor if you notice yellowing of your skin or eyes, persistent fatigue, abdominal swelling, or easy bruising. Also get checked if you have risk factors like heavy drinking, obesity, diabetes, or known hepatitis infection. Don't wait for symptoms, as early liver disease is often silent. Regular blood testing helps catch problems before you feel sick.
Liver failure means your liver can no longer perform essential functions. You may develop severe confusion, bleeding problems, kidney failure, and fluid buildup. This is a life-threatening condition that requires hospital care. At this stage, liver transplant may be the only treatment option. This is why early detection and management are so critical.
