Chronic Liver Disease: An Expert Guide on Causes, Symptoms and Treatment
Verified by: Dr. Divya Cadabam
The progression of chronic liver disease is insidious, yet it can result in significant and permanent damage.
This guide aims to enhance your understanding of the most common forms of liver disease by outlining their aetiology, signs and symptoms, stages, and therapeutic approaches so that you are equipped to act early if needed.
What is Chronic Liver Disease?
Chronic liver disease is more common in regions with low and middle-income populations due to having lifestyle-based risk factors like obesity. CLD (Chronic liver disease) is very problematic on a global scale because of its high dependency rates.
The disease starts developing because of an inflamed liver, which injures it over time. Failing to take swift action will result in cirrhosis, liver failure or severe complications.
Overview of Chronic Liver Disease
The liver is responsible for breaking down and purifying blood, maintaining the body’s metabolism, and aiding digestion. If fibrosis is left untreated, it slowly over time becomes worse.
Treatment is essential; without intervention, the damage can reach a stage that is beyond no return, because it cripples the person’s lifestyle.
Difference Between Acute and Chronic Liver Disease
Acute liver disease has a sudden onset, with the potential to clear up if treated properly. This contrasts with Chronic liver disease, which has a gradual deterioration of liver health. Acute forms of the disease often go unnoticed during the initial scarring stage, ultimately leading to the chronic form going mis-diagnosed.
The ICD-10 classification code for chronic liver disease is K76.9, which is often utilised in different documentation of the disease.
Epidemiology of Chronic Liver Disease
CLD (Chronic liver disease) has an increasing incidence, especially in low- and middle-income countries. These, along with a few other factors, put chronic liver disease at risk for public health systems. This along with lifestyle changes and succumbing to obesity,
CLD is extremely problematic in countries like India. CLD continues to remain one of the top causes of death around the globe, slowly creeping up the hierarchy of doom, ranking in the top ten greatest contributors to disability.
Global Prevalence of Chronic Liver Disease
Approximately 1.5 billion people struggle from chronic liver disease in the world, and around 2 million deaths take place each year.
The impact is increasing globally, particularly due to the rise of cirrhosis and liver cancer in metabolic and alcohol-induced cases. There is a necessity for screening and awareness so that this toll can be reduced.
Prevalence by Region and Population
This area of study is focused on the regions due to their trends. In Asia and Africa, viral hepatitis dominates, while in the Western nations, alcoholic and metabolic disorders take priority when it comes to chronic liver disease. Regional data also show great differences in the availability of treatment.
Influence of Race, Ethnicity, and Socioeconomic Factors
Social determinants contribute to this disorder. Minority ethnic groups and lower socioeconomic groups have been shown to have greater exposure to the risk factors while having minimal access to early detection and treatment through screening.
Cultural norms and stigma surrounding the illness could also postpone seeking healthcare services.
Risk Factors and Who is at the Most Risk for Chronic Liver Disease
There are several medical and genetic conditions, as well as lifestyle choices, which increase the likelihood of getting chronic liver disease.
This understanding can assist in preventive care in the future, especially in addressing vulnerable populations. Early identification of risks helps in providing timely corrective measures before complications arise.
Major Risk Factors for Chronic Liver Disease
Risk factors include lifestyle habits, infections, and environmental exposures.
- Excessive Alcohol Consumption: Considered the greatest driver of liver inflammation and cirrhosis.
- Metabolic Syndrome Encompasses obesity, insulin resistance, and increased hypertension.
- Viral Hepatitis B & C: May cause chronic inflammation and fibrosis over time.
- Genetic Liver Disorders: Conditions such as hemochromatosis and Wilson’s disease disrupt metal metabolism.
- Autoimmunology: The body’s defence system erroneously targets liver tissues.
- Exposure to Industrial Chemicals, Drugs, and Dietary Supplements: Such as herbal medicines harms hepatocytes.
- Nutritional: Diets rich in sugars and fats contribute to steatosis.
Populations at Increased Risk for Chronic Liver Disease
Some populations are particularly targeted owing to biological or sociocultural factors.
- People with Metabolic Syndrome: Their hepatic steatosis is more pronounced.
- Chronic Alcohol Users: Women may experience a more rapid progression because of certain physiological factors.
- Individuals with Chronic Viral Hepatitis: Especially in the absence of antiviral therapy.
- Carriers of Genetic Disorders: Inherited liver diseases are frequently asymptomatic until significant damage occurs.
- Social Economic Risk Groups: Poor health care access disproportionately increases risk and worsens these outcomes.
- Elderly (50+ Years): Advanced age diminishes these factors.
Causes of Chronic Liver Disease
The underlying contributors to CLD are multifactorial. Understanding the underlying contributory factors is essential for developing a treatment strategy, planning interventions to slow progression, and timely shifting care levels. Each factor leads to specific changes in the liver that are injurious over time.
Viral Hepatitis
CLD is one of the most prevalent complications of both Hepatitis B and C infections. Due to cascading liver inflammation, the infected individual faces a risk of cirrhosis and hepatocellular carcinoma. Available vaccines, along with antiviral therapies, have been successful in curtailing fresh infections.
Alcoholic Liver Disease
The condition stems from powerful sociocultural implications. Advanced stages lead to persistent depletion of liver tissues that are permeable to scarring. Moderation in alcohol consumption serves as the foremost therapeutic strategy.
Metabolic Dysfunction–Associated Steatosis Liver Disease (MASLD)
MASLD is utilised to designate a syndrome previously referred to as NAFLD and outlines a more expansive classification. The surge in CLD around the world is attributed to climbing rates of obesity and diabetes. Single-handedly, the syndrome tends to remain unresponsive to concealment until it gets quite advanced.
Autoimmune Hepatitis
As the name suggests, the condition stems from attacking one’s liver, leading to gradual fibrosis and cirrhosis over time. Medical therapy can improve outcomes if proper immunosuppressive treatments are initiated early.
Genetic Liver Disorders (Hemochromatosis & Wilson’s Disease)
These hereditary disorders lead to the abnormal deposition of iron or copper in the liver. If left untreated, the deposits may harm the liver considerably. Genetic testing, alongside complex treatments that often span a lifetime, is needed.
Non-Viral Infections & Parasitic Diseases (Schistosomiasis)
Schistosomiasis is an example of a parasitic infection that can lead to liver fibrosis. High rates can be found in regions with low sanitation and water quality. Long-lasting infection results in portal hypertension and damage to other organs.
Drug-Induced Liver Disease
Herbal medicines, dietary supplements, and some drugs can result in liver damage. The risk is even greater with high dosages, chronic use, or with other concomitant liver diseases. Regular liver function tests provide safety monitoring.
Primary Biliary Cholangitis (PBC)
This is an autoimmune disease that progressively and slowly damages intrahepatic bile ducts. Bile accumulates and then slowly transforms into scarred liver. PBC is one of the most frequently diagnosed forms of cholesterol gallstone disease in women. Ursodeoxycholic acid is a treatment commonly used for this disease.
Primary Sclerosing Cholangitis (PSC)
The central feature of this condition is progressive inflammation and scarring of the bile ducts. This condition is often associated with inflammatory bowel disease, and it increases the risk of cancer. Although rare, the disease is relentless, and individuals usually require a liver transplant.
Toxin Exposure & Industrial Chemicals
Industrial Chemicals containing vinyl chloride may potentially lead to malignant liver damage. Protective actions and policies should be given higher emphasis. Workers in particular fields should be screened regularly for liver health.
Right-Sided Heart Failure & Congestive Hepatopathy
In right-sided heart failure, liver damage can occur due to congestion when blood backs up the body. This results in congestion and impairment, which may culminate in fibrosis. Haptic symptoms markedly improve when the cardiac condition is managed, so treating the primary diagnosis is crucial.
Symptoms of Chronic Liver Disease
Symptom monitoring is critical for the prevention of acute complications. The early signs require attention, as they're often subtle and deceiving, while the latter stages depict serious liver decompensation.
Early Symptoms of Chronic Liver Disease
Chronic diseases manifest vague symptoms like mild abdominal discomfort, peripheral fatigue, anorexia, and malaise. Such signs are often dismissed or attributed to overwork. Proactive assessment can increase the chances of early intervention.
Advanced Symptoms of Chronic Liver Disease
Decompensated CLD manifests with encephalopathy, ascites/jaundice, increased bruising/bleeding, and impaired liver synthesis. These almost always indicate some degree of decompensation, and urgent intervention is required. Very often, at this point, the intervention shifts to complication control and maintenance of liver function.
Stages of Chronic Liver Disease
Like most diseases, chronic liver diseases are progressive: they begin with a specific set of pathophysiological changes, and over time, these changes increase in severity and risk. These processes may be altered to slower progress or even reversed if addressed early on. Different stages clarify the goals and enhance predictors of prognosis.
Fibrosis
The liver still works well, although ongoing damage can push it toward cirrhosis. Fibrosis is the early stage of liver scarring—inflammation starts to replace healthy liver tissue with scar tissue—and is still reversible with lifestyle and medical intervention. With cirrhosis, liver function and damage increase.
Cirrhosis
This stage represents advanced and partially irreversible scarring, with persisting elevation of scar tissue disrupting liver architecture and hepatoportal vascular flow. At this stage, some degree of liver function impairment and clinical symptoms may begin to manifest. While fully reversible cirrhosis does not exist, its progression can be arrested with effective management.
Decompensated Cirrhosis
This is the end stage of liver disease with complete loss of liver function. The common symptoms of this stage include jaundice, ascites, confusion, and various bleeding complications. This stage often results in hospitalisation and evaluation for a possible liver transplant.
Diagnosis of Chronic Liver Disease
CLD diagnosis is done through a comprehensive panel combining blood work, imaging, and sometimes even biopsy to determine the scope of damage inflicted on the liver. Early diagnosis has a notable impact on the outcome. For early diagnosis and tailored management, Cadabam's Diagnostics provides integrated testing services.
Laboratory Tests
Liver function tests, including ALT, AST, and bilirubin, assess the liver’s detoxification and bile production functions. Coagulation profiles offer a window into blood-clotting complications resulting from liver disease. These tests are routine initial procedures in troubleshooting liver distress.
Imaging Studies
Ultrasound evaluates the liver’s texture, size, and fat content. Nodules and tumours, as well as more advanced cirrhosis, can be detected using CT scans and MRIS. Imaging assists in the evaluation of disease and in determining further treatment intervention.
Treatment Options for Chronic Liver Disease
Disease Management of CLD focuses on treating the underlying cause, preventing further damage, and improving quality of life. Relieving symptoms alongside some combination of lifestyle changes, medications, and in some cases, surgical options is considered most useful. Treatment can stop or reverse liver function deterioration if provided early.
Lifestyle Modifications
Making small changes to everyday habits may greatly assist in slowing the progression of liver disease.
- Alcohol Cessation: Stopping alcohol altogether prevents further damage in alcoholic liver disease.
- Employee by a Weight Loss Plan: Aids in decreasing liver fat and enhancing insulin sensitivity.
- Quit Smoking: Smokers struggle with less oxidative stress to the liver.
- Better Management of Stress & Improved Sleeping Patterns: Enhance immune function, neuroendocrine function, recovery and overall healing.
Medications
- Medications are specifically designed based on the causes and symptoms of CLD.
- Antiviral Therapy for Hepatitis B & C: Lessens the viral presence and inflammation in the liver tissues.
- Medications for NAFLD & NASH: Comprises insulin sensitisers and vitamin E.
- Diuretics for Ascites & Oedema: Alleviates fluid accumulation within the abdominal cavity.
- Liver Transplantation: Recommended for end-stage liver disease where other interventions have not succeeded.
Prevention Strategies for Chronic Liver Disease
Informed and healthy living habits form the foundation for preventing chronic liver diseases (CLD). Minimisation of risk factors alongside routine monitoring can postpone or circumvent the onset of the disease. High-risk communities require education and accessible healthcare.
Healthy Eating Habits
Maintaining liver health necessitates good nutrition.
- Implementing a Mediterranean Diet: Promotes the consumption of olive oil, vegetables, and lean meats.
- Reducing Sugar & Processed Foods: Aids in decreasing liver fat.
- Increasing Antioxidants & Fibre: Enhances detoxification and digestion.
- Avoiding Excess Salt & Reducing Alcohol Consumption: Decreases inflammation and strain on the liver.
Regular Physical Activity
Physical activity diminishes liver fat and enhances liver metabolism.
Fat Metabolism Aerobic Exercises: 30 minutes of daily walking, cycling, or swimming.
Resistance Training improves insulin sensitivity by increasing muscle mass and enhancing glucose control.
Yoga and stress relief bolster emotional and hormonal equilibrium, aiding overall wellness.
Physical Activity Guidelines by Disease Stage: Adjust intensity based on liver function, fatigue, and overall wellness.
Preventive Measures for High-Risk Individuals
People who have risk factors need special protection and regular check-ups.
Though Alcohol moderation can control CLD, Regular Exercise, a healthy diet, and Alcohol moderation are preventive measures.
High-risk individuals must take the hepatitis B vaccine. Cadabam’s performs assessments every six months for check-ups and liver function tests. The liver damage is treated at the onset.
