Liver Disease: Symptoms, Causes, and Treatment Options

Liver Disease: Learn about the symptoms, causes, risk factors, and available treatment options for various liver conditions, including hepatitis, cirrhosis, and liver cancer.

Liver disease is a serious issue that affects many worldwide. The liver manages crucial functions, such as filtering toxins from the blood.1 Yet, this role exposes it to harm. When overwhelmed, the liver can sustain lasting damage. This leads to conditions like chronic liver disease.1

To understand liver disease, it’s helpful to know its stages. These include hepatitis, fibrosis, cirrhosis, and eventually, liver failure.1 Knowing these stages is key to find it early, manage well, and maybe find treatment. Doctors use tests like blood work and biopsies to check liver health and find the cause of the disease.2

Liver disease’s impact is big, in the U.S. and worldwide.1 Around 1.8% of U.S. adults, or 4.5 million people, have liver disease.1 Sadly, it causes about 57,000 U.S. deaths yearly.1 The global effect is even worse, with about 2 million deaths each year. This is 4% of all deaths.1

Key Takeaways

  • Liver disease is a chronic condition that can lead to progressive damage and liver failure if left untreated.
  • The liver plays a vital role in filtering toxins from the body, making it vulnerable to the very substances it processes.
  • Liver disease affects an estimated 1.8% of U.S. adults and is a leading cause of death globally.
  • Diagnostic tools like blood tests, imaging scans, and liver biopsies can help identify the underlying causes of liver disease.
  • Treatment options for liver disease range from lifestyle modifications to medications and, in severe cases, liver transplantation.

What is Liver Disease?

The liver is a vital organ that does many jobs, like cleaning the blood from toxins.1 But if the liver faces too many toxins, it might not work well. This could lead to liver disease.1

Understanding the Liver’s Functions

The liver is key to keeping us healthy. It helps with blood sugar, bile, and deals with hormones and drugs.3 If it gets hurt, it affects the whole body.

Stages of Chronic Liver Disease

Chronic liver disease has four main stages: hepatitis, fibrosis, cirrhosis, and liver failure.1 Hepatitis is where the liver swells. It can then lead to fibrosis, where scar tissue starts forming. With more damage, this scarring can become permanent in cirrhosis. After cirrhosis, the liver can’t heal enough, causing it to fail.1

Prevalence of Liver Disease

Liver disease greatly affects public health in the U.S. and around the world. About 4.5 million adults in the U.S. have it, which is 1.8% of all U.S. adults.4 It causes some 57,000 deaths in the U.S. yearly.4 Globally, it leads to about 2 million deaths annually.4

Statistics on Liver Disease in the United States

In the U.S., liver disease affects men much more than women. Men and those assigned male at birth are twice as likely to suffer from it.4 This big gap shows the importance of special programs to help different groups.

Global Impact of Liver Disease

Worldwide, liver disease is a major health issue. It often leads to severe illness and death. Each year, about 2 million people die from it around the globe.4 This highlights the urgent need for global efforts. These efforts focus on preventing and treating liver disease.

Liver Disease Prevalence

Symptoms of Liver Disease

Early stages of liver disease may not show clear symptoms. But as it gets worse, you may notice several signs.5 One common sign is jaundice, which turns the skin and eyes yellow. This happens when there’s too much bilirubin in the blood.5 If the flow of bile is blocked, it can also cause jaundice. You might see dark urine and pale stools then.5 Feeling full or having pain in the stomach can be linked to liver enlargement.

Early Warning Signs

Feeling tired, stomach pain, and skin or eye color changes can be early signs of liver issues.5 Other early symptoms include feeling sick, not wanting to eat, and spotting blood in the stool.6

Advanced Symptoms

Later, more severe symptoms can happen with liver disease.5 Problems like high blood pressure in the portal vein can lead to a swollen belly (ascites) and esophageal varices.5 These varices are blood vessels in the esophagus that may make you spit up blood, have black stools, or feel weak.5 Fluid in the stomach (ascites) can occur with serious liver conditions, too.5 If the liver builds up toxins and can’t work well, this can affect the brain. You might get confused, have trouble thinking, or even have a seizure.5 Severe liver failure brings jaundice, bruising easily, and a general feeling of being unwell.5

Causes of Liver Disease

Chronic liver disease can come from viral infections, toxic poisoning, and specific metabolic issues.3 Key causes of liver failure are viral hepatitis, alcoholic liver disease, and non-alcoholic fatty liver disease.

Viral Hepatitis

Hepatitis B and C viruses cause viral hepatitis.3 They can lead to ongoing liver inflammation and scarring if not treated. Viral infections are one of the main drivers of liver disease.

Alcoholic Liver Disease

Too much alcohol can harm liver cells and cause cirrhosis.3 Drinking a lot or even moderately increases the risk of getting this liver disease.

Non-Alcoholic Fatty Liver Disease

Fatty liver disease without alcohol links to being overweight, diabetes, and metabolic problems.3 It can turn into cirrhosis. Keeping a healthy weight and managing metabolic issues is key to avoid liver problems.

Causes of Liver Disease

Risk Factors for Liver Disease

While we don’t always know the exact causes of liver disease, there are clear risk factors.7 These can come from our genes and the way we live. Understanding these risks is key to preventing and catching liver disease early.7

Genetic Factors

Doctors often ask about your family’s health when diagnosing liver issues. This means genetic factors might make you more likely to get liver disease.7 If liver disease runs in your family, you might be at higher risk for certain types.8

Lifestyle Factors

How we live also matters. For example, drinking a lot or being very overweight can up your risk of liver troubles.9 Just a few drinks a day can kickstart a problem like alcoholic fatty liver disease.8

Being overweight or having diabetes can lead to non-alcoholic fatty liver disease. This could eventually cause serious liver issues, like cirrhosis.8 Plus, too many toxins can be bad for your liver.8

Knowing about these risks allows you to make smart choices. This can help keep your liver healthy and avoid serious liver disease.89

Diagnosing Liver Disease

Diagnosing liver disease involves many tests.10 These can include blood, imaging, and liver biopsy tests.

Blood Tests

Liver function tests are key in spotting liver damage and issues.10 They look at enzymes and proteins in the blood.10 This helps check liver health and see how treatments are working.

Imaging Tests

Tests like ultrasounds and MRIs show the liver’s structure.10 They can also check liver stiffness and fibrosis.10 But, they aren’t great for fatty liver or NASH diagnosis.

Liver Biopsy

Sometimes, a liver biopsy is needed for a precise diagnosis.10 It means taking a small liver sample for testing.10 There are different ways to do this.

Before a biopsy, blood tests rule out clotting problems.10 There are some risks, like bleeding or infection.10

Using all these methods together helps doctors make a clear diagnosis. This leads to the best treatment decisions for patients.

Treatment Options for Liver Disease

The way we treat Liver Disease changes with its cause and how advanced it is.1 Certain liver issues can get better by changing your lifestyle. This includes things like shedding extra pounds, cutting back on drinks, and eating well.2 Changing how you live by losing weight and lessening alcohol can boost your liver’s health.2

Lifestyle Modifications

Getting into healthier routines is key for dealing with liver disease.2 Making lifestyle changes can enhance your liver’s condition.2 It helps a lot to eat well, work out often, and keep your weight in check.1 Around 1.8% of adults in the U.S. (that’s 4.5 million people) have liver disease. For them, tweaking how they live is a good way to handle the illness.


2 Healthcare providers might also use medicines to treat different liver problems or their signs. The right meds can deal with the root cause of liver disease, like viral hepatitis or autoimmune issues.11 Acetaminophen is okay to use for pain if you have cirrhosis, but not more than two grams a day. People with cirrhosis should also keep their salt intake under two grams per day.

Surgical Interventions

If liver disease gets really bad and causes total failure,2 you might need a liver transplant.2 But bear in mind, cirrhosis sometimes can’t be totally fixed. Staying away from alcohol, losing weight, and using certain antiviral medicines for hepatitis C can slow down or even fix some liver damage.

2 It’s vital to steer clear of certain supplements and meds that could harm the liver.2 Vitamin A, Ma-huang, Germander, and a few other natural remedies can be bad for your liver. Always talk with your healthcare provider before you take any alternative treatments.

Liver Disease and Liver Failure

Liver failure happens when the liver can’t keep up with the body’s needs.12 The liver gets to a point where it can’t heal itself from damage and losing cells. This is called “decompensated cirrhosis.”13 People with Liver Failure start having symptoms all over.13 Over time, Chronic liver failure gets worse. Without a liver transplant, it can be deadly since the liver is crucial for life.12

Long-term liver damage leads to Chronic liver failure.12 On the other hand, Acute liver failure happens fast, within days or weeks. It doesn’t need a previous liver problem.12 Things like too much acetaminophen, hepatitis, and bad reactions to meds can cause acute liver failure.12 But, Chronic liver failure often comes from hepatitis B and C, drinking a lot over the years, and hemochromatosis.12

There are four stages of liver disease: inflammation, scarring, cirrhosis, and end-stage liver failure/disease.12 Doctors use blood tests, ultrasounds, and biopsies to diagnose Liver Failure and liver problems.12 Ways to treat Liver Failure include meds, supportive care, and sometimes a liver transplant.12

Stopping Liver Failure means avoiding cirrhosis or hepatitis. Get vaccinated, eat well, keep a healthy weight, don’t drink too much, stay clean, and avoid sharing needles.12 It’s also key to act early and manage the problem to prevent it from getting life-threatening.

Managing Liver Disease

If you have liver disease, changing how you live is key to taking care of your liver.2 The second source gives tips on what to eat and how to exercise to keep your liver in good shape and stop more harm.

Dietary Recommendations

Eating right is crucial for anyone with liver disease. The second source recommends a diet full of fruits, veggies, and whole grains.2 It also says to cut back on sugar, fructose, and bad fats. Keeping to this diet helps your liver work better and lessen its load.

Exercise and Weight Management

Staying at a healthy weight and being active matter a lot for liver disease.2 The second source warns that being too heavy and not moving enough can make liver issues worse. This is especially true for a disease like non-alcoholic fatty liver disease.14

Adding exercise to your day and aiming for a good weight can boost your liver and make you feel better. It’s a big part of handling liver disease.

Changing how you live can really help if you have liver disease.2 A mix of good eating, staying active, and watching your weight is a strong way to take care of your liver and slow disease down.

Liver Transplantation

A liver transplant can become the only hope for someone with severe liver disease. This disease often ends up in liver failure.15 Cirrhosis is a key reason for needing a new liver. It is mostly caused by hepatitis B and C, and by alcohol or fat building up in the liver. Other reasons include genetic issues and problems with bile ducts. Biliary atresia is a common reason kids might need a liver transplant.15

Eligibility Criteria

To be considered for a liver transplant, patients are checked by healthcare teams. They look at how bad the liver disease is, the patient’s general health, and if the transplant will likely work well.16 There could be problems after the surgery, like the body rejecting the new liver. Patients then have to take medicine for this all their lives.16 Also, some liver diseases might come back after a transplant and need to be treated right off.16

Transplant Process

Getting a new liver is a big operation that keeps the patient in the hospital for a while. It varies from person to person. Everyone has to stay in the ICU at first, often needing help to breathe until they can do it on their own.16 Doctors will keep a close eye on the patient’s blood to make sure the new liver and the body’s systems are working right.16 But, the medicine to prevent the body rejecting the new liver can make patients more likely to get sick.16 So, patients might catch things like yeast infections in their mouth, herpes, or viruses that affect breathing. Signs the body might be rejecting the new liver include fever, yellowing skin or eyes, dark pee, feeling itchy, and being very tired.16 It’s important for patients to stay away from sick people at first. They need to tell their doctor right away if they feel like the surgery’s gone wrong, or if they think they’re getting sick.16

Liver Disease Prevention

It’s important to keep our liver healthy because it does many key tasks in our body. For example, it cleans the blood by removing harmful substances.3 But, the liver can get sick from the very things it’s trying to clean. This can cause serious problems like liver disease.3

Vaccination for Hepatitis

Vaccines are very good at preventing liver disease, especially from hepatitis B and C.14 These are serious viral infections that can damage the liver. Getting vaccinated is a crucial step in avoiding these risks.3

Alcohol Moderation

Limiting how much alcohol we drink is also key to avoiding liver diseases.14 Alcoholic liver disease is a big worry for heavy drinkers. It can lead to dangerous liver conditions like cirrhosis.3

Maintaining a Healthy Weight

Staying at a healthy weight and tackling health issues like obesity and diabetes can prevent liver problems.14 Being overweight can cause a type of liver disease. This is now known as metabolic-associated steatotic liver disease.3

To keep your liver in good shape, it’s vital to get the right vaccines, not drink too much, and stay at a healthy weight. Doing these things can lower your chances of long-term liver diseases and their serious effects.314

Liver Disease: Symptoms, Causes, and Treatment Options

Liver disease is a big worry for many people worldwide and in the United States.1 About 4.5 million U.S. adults deal with liver disease. This leads to approximately 57,000 deaths yearly in the U.S.1 Across the globe, liver disease is behind roughly 2 million deaths every year, making up about 4% of all deaths.1 The liver is a vital organ, working hard to process toxins from our blood.3 But, it faces risks because it filters these toxins. If there are too many toxins, it can cause the liver to become ill.

Liver disease starts gradually and can take different forms. Initially, there’s inflammation (hepatitis), which can worsen to scarring (fibrosis and cirrhosis), and finally, complete liver failure.1 Conditions like fatty liver disease and cirrhosis can bring on jaundice, swelling, itchy skin, and fatigue.3 There are many causes of liver disease, ranging from viral infections to toxic poisoning and certain metabolic issues.13 Things like too much alcohol, obesity, and diabetes can also put you at risk.3

There are different treatments for liver disease, depending on the cause and how severe it is.3 Changing your lifestyle, like losing weight and cutting back on alcohol, can help manage the problem.3 Sometimes, doctors use medications to treat liver issues or their symptoms. In serious cases of liver failure, a liver transplant might be needed.3

The best way to deal with liver disease is to prevent it. This means getting vaccinated against hepatitis, limiting alcohol, staying at a healthy weight, and being careful with drugs that can hurt your liver.3 Knowing the signs, causes, and treatment options can help you keep your liver healthy. This way, you can lower your chances of getting a serious liver disease.

Emerging Treatments for Liver Disease

The number of liver disease cases is going up worldwide. This has led researchers and doctors to look for new treatments to help patients. Stem cell therapy and gene therapy are two such treatments. They are showing great potential in improving how we deal with liver diseases.17

Stem Cell Therapy

Stem cell therapy offers hope in treating liver disease. Scientists are learning how to use stem cells to make different types of liver cells. When these stem cells are placed in the liver, they encourage the growth of new, healthy liver tissue. This can help the liver work better.17

One study found that a drug called HRX215 could boost liver regrowth. Even after removing most of an animal’s liver, HRX215 made new liver cells grow. This is good news for people with liver failure. It means that a drug like HRX215 could help their livers heal.17

Gene Therapy

Gene therapy is also becoming more important in liver disease treatment. By changing the liver’s genes, researchers hope to target the causes of liver diseases. This could fix the liver issues at their source.18

For example, Rezdiffra is a drug for a specific liver condition called MASH. It’s for people whose livers are damaged and close to cirrhosis. Rezdiffra aims to help these patients. But, like any drug, it might cause side effects such as diarrhea and nausea.18

The work on these new treatments is still ongoing. Organizations like the Mayo Clinic are leading these efforts. They aim to make life better for those with liver disease. It’s a promising time for liver disease research and treatment thanks to their hard work.17

Living with Liver Disease

Living with liver disease brings its own set of hurdles. Yet, with the right support and strategies, people can manage and lead fulfilling lives.19

Support Groups

It’s invaluable to connect with others facing similar challenges, especially if you have [Living with Liver Disease]. Being part of a support group, either local or online, offers a community, emotional help, and practical advice. This comes from those who truly understand what it’s like.19

There are many support groups available through hospitals, clinics, and organizations focused on liver diseases. These are great for sharing experiences, gaining insight from others, and discovering new coping methods for the physical and emotional struggles of [Liver Disease Support Groups].19

Coping Strategies

Finding good [Coping with Liver Disease] strategies is key for those with liver issues. This might mean choosing a healthy way of life. For example, one could focus on eating well, staying active, and steering clear of alcohol and specific drugs that harm the liver.1920

Making mental and emotional health a priority also helps. Things like managing stress, counseling, and support systems are beneficial for navigating the challenges. Keeping up good communication with healthcare teams and active involvement in managing the condition can give patients a sense of control over [Living with Liver Disease].19

By using support groups and effective coping strategies, those with liver disease have the potential for better well-being and life quality. This is even in the face of the difficulties they encounter.19


Liver disease is a big issue in the U.S. and worldwide. About 4.5 million U.S. adults have it. It takes about 41,473 lives in the U.S. yearly.21 This disease is a common cause of death globally, especially in developing countries.21

This article also discussed what causes liver disease. Some main causes are viral hepatitis and alcohol-related problems.21 To diagnose it, doctors use blood tests, imaging, and sometimes liver biopsy.22 Treatment includes changing your lifestyle, taking medications, or even having a liver transplant.23

Liver disease research is ongoing. New approaches in genomics are helping us understand and treat it better.23 By spreading awareness and pushing for better prevention and healthcare, we can make a difference.212322
