Chronic liver disease and its management
Know your Liver
The liver is a large, reddish-brown organ located in the upper right side of the abdomen, just below the diaphragm. It is the body's largest internal organ and performs essential functions such as filtering toxins from the blood, producing bile for digestion, storing energy in the form of glycogen, and helping in the metabolism of nutrients, medications, and hormones.

The liver is on the right side of your body, just below your rib cage
The liver has tiny tubes called bile ducts that carry bile (a yellow-green liquid) to the gallbladder, where it's stored until your body needs it to digest fats. It's closely connected to the stomach, intestines, and gallbladder, as they all work together for digestion.
The liver is super important because it acts as the body's chemical factory, storage unit, and waste manager—all rolled into one!
The liver is an essential organ in your body that performs many important jobs, such as:
- 1. Filtering Blood: It cleans your blood by removing toxins and waste products.
- 2. Producing Bile: This helps digest fats in your food.
- 3. Storing Energy: It stores sugar in the form of glycogen to give you energy when you need it.
What is Chronic Liver Disease ?
Chronic liver disease is a long-term condition where the liver gets damaged over time. This can happen due to various reasons, like alcohol use, infections like viral hepatitis (B, C), fatty liver disease (NAFLD/NASH), autoimmune diseases, certain medications and others.
The damage makes it hard for the liver to do its important jobs, such as filtering toxins, producing bile, storing energy and synthesizing proteins and clotting factors.
Progression of Chronic Liver Disease
- 1. Healthy Liver:
- The liver is functioning well, with no damage. It looks smooth, reddish-brown, and performs its tasks without issues. Refer figure 1 given below.
- 2. Fatty Liver (Steatosis):
- Too much fat builds up in the liver due to poor diet, obesity, or alcohol. The liver may still work normally, but it’s under stress.
- 3. Inflammation (Hepatitis):
- The liver gets swollen and irritated, usually due to infections (like hepatitis B or C), alcohol, or fat build-up. This is a warning sign of trouble.
- 4. Fibrosis:
- Scar tissue forms as the liver tries to heal itself. The scarring is patchy at this stage, and some parts of the liver still work.
- 5. Cirrhosis:
- Severe scarring spreads across the liver. It becomes smaller, hard, and struggles to function. Symptoms like yellow skin (jaundice), swelling, and fatigue may appear.

Figure 1 Progression of Chronic Liver Disease
What is Cirrhosis?
- Cirrhosis is the scarring of the liver caused by long-term damage.
- In cirrhosis, healthy liver tissue is replaced by scar tissue results in impaired liver function.
Effects of cirrhosis:
-
Ascites: Portal hypertension leads to increased hydrostatic pressure, causing fluid to accumulate in the peritoneal cavity. Hypoalbuminemia (deficiency of protein in blood) further decreases oncotic pressure.
-
Variceal Bleeding: Increased portal pressure causes dilation of collateral veins (Esophageal and gastric varices), which can rupture and bleed due to increased tension.
-
Hepatic Encephalopathy (HE): Impaired liver detoxification leads to ammonia accumulation, crossing the blood-brain barrier and causing neurological dysfunction.
-
Jaundice: Impaired bilirubin metabolism results in its build-up in the blood, leading to yellowing of the skin and eyes.
-
Coagulopathy: Decreased synthesis of clotting factors by the liver leads to bleeding tendencies.
-
Hepatorenal Syndrome: Severe vasoconstriction in the renal circulation due to systemic vasodilation and reduced renal perfusion.
-
Spontaneous Bacterial Peritonitis (SBP): Bacterial translocation from the gut into ascitic fluid due to immune dysfunction and gut permeability.
Symptoms and Signs:
- Jaundice (yellowing of the skin/eyes), fatigue, swelling in the abdomen and legs (ascites), easy bruising, confusion (hepatic encephalopathy), and variceal bleeding (bleeding from veins in the esophagus or stomach).
- Cirrhosis can progress from compensated (mild) to decompensated (severe), where complications like ascites, variceal bleeding, and hepatic encephalopathy occur.
Why Cirrhosis Needs to Be Managed?
- Without proper treatment and lifestyle changes, cirrhosis can lead to liver failure and other life-threatening complications.
Management of Chronic Liver Disease
Chronic liver disease means that the liver has been damaged over a long period of time. Although the damage may not be completely reversible, proper management can slow disease progression, prevent complications, and improve quality of life.
-
1. Healthy Lifestyle Changes
Balanced Diet- Eat fresh fruits, vegetables, whole grains, and pulses
- Include adequate protein (unless advised otherwise by the doctor)
- Avoid fried, fatty, and junk foods
- Reduce salt intake, especially if there is swelling or fluid in the abdomen
- Drink safe and clean water
A healthy diet helps reduce stress on the liver and supports healing.
Complete Avoidance of Alcohol- Alcohol further damages the liver and speeds up disease progression
- Stopping alcohol completely is the most important step in management
- Seek help from counseling or de-addiction program at AUD clinic at ILBS
-
2. Regular Medical Care
Follow-Up Visits- Attend regular check-ups with your healthcare provider
- Do not miss appointments even if you feel well
Medicines as Prescribed
- Take medications exactly as advised
- Do not stop or change medicines without consulting your doctor
- Avoid over-the-counter drugs and herbal medicines unless approved
Some medicines can harm the liver if taken without guidance.
-
3. Preventing Infections
Vaccinations- Get vaccinated against Hepatitis A and Hepatitis B
- Stay updated on other recommended vaccines
Personal Hygiene
- Wash hands before eating and after using the toilet
- Avoid sharing razors, toothbrushes, or needles
-
4. Monitoring for Complications
Patients with chronic liver disease should watch for warning signs or worsening of symptoms:
- Yellowing of eyes or skin (jaundice)
- Swelling of legs or abdomen
- Easy bleeding or bruising
- Black stools or vomiting blood
- Confusion, drowsiness, or memory problems
Report these symptoms immediately to the doctor.
-
5. Fluid and Salt Management
- Limit salt intake to prevent fluid buildup. Follow the doctor’s or the dietician’s advice for fluid and salt intake.
- Daily measure weight if advised
- Follow fluid restriction if prescribed
-
6. Physical Activity and Rest
- Engage in light to moderate physical activity like walking
- Avoid heavy lifting or strenuous exercise
- Take adequate rest and sleep
-
7. Mental and Emotional Well-Being
- Living with chronic illness can cause stress or anxiety
- Talk openly with family members and healthcare providers
- Seek psychological support or counseling if needed.
-
8. Avoid Harmful Substances
- Do not smoke or chew tobacco
- Avoid exposure to chemicals or toxins
- Use painkillers like paracetamol only in safe doses
Chronic liver disease can be managed successfully with regular care, healthy habits, and early treatment of complications. Active participation in your care is the key to living a better and longer life.
In some patients with advance disease, certain advance treatment modalities may be prescribed by the hepatologists. These are explained in the following sections.
Transjugular Intrahepatic Portosystemic Shunt (TIPS) Procedure
What is TIPS procedure?
TIPS is a procedure used to treat portal hypertension which is common complication of cirrhosis, where high pressure in the portal vein can lead to complications like variceal bleeding or ascites.
How TIPS Works:
The procedure involves creating a shunt (channel) between the portal vein and the hepatic vein in the liver, reducing the pressure in the portal vein and improving blood flow.
Indications for TIPS:
Refractory/recurrent ascites that cannot be controlled with medications.
Recurrent variceal bleeding that cannot be managed with endoscopic treatments.
Other complications of portal hypertension.
Procedure Overview:
Performed under local anaesthesia and sedation.
A catheter is inserted through the jugular vein in the neck, guided to the liver, and a shunt is placed to connect the portal vein to the hepatic vein.
It is typically done in a hospital setting and within 1 hour 30 minutes (approximately)
Preparation
-
1. Medical Evaluation and Risk Assessment
- Comprehensive evaluation of liver function (LFTs), kidney function, and coagulation profile.
- Cardiac evaluation if required, especially in patients with a history of heart disease.
-
2. Informed Consent and Education
-
3. Fasting and Medication Adjustments
- Instruct the patient to fast (avoid food and drink) for at least 6-8 hours before the procedure.
-
4. Adjust medications:
- Stop anticoagulants and antiplatelet drugs under medical guidance to reduce bleeding risk.
- Continue essential medications (e.g., for hypertension or diabetes) as directed by the doctor.
-
5. Physical Preparation
- Ensure the patient wears loose, comfortable clothing and removes all jewellery before arriving at the hospital.
- Place an intravenous (IV) line for hydration and medication administration.
Benefits of TIPS Over Pharmacological Treatment Only
-
1. Better Control of Portal Hypertension
- TIPS significantly reduces portal pressure gradient (PPG) compared to drugs alone.
-
2. Lower Risk of Recurrent Variceal Bleeding
- TIPS reduces re-bleeding rates more effectively than beta-blockers and endoscopic therapy in high risk bleeders ( CTP B with active bleeding on endoscopy and CTP C <13).
- Provides immediate control of active bleeding.
-
3. Improved Management of Refractory Ascites
- Enhances fluid reabsorption, reducing the need for large-volume paracentesis (LVP).
- More effective than diuretics in patients with severe ascites.
-
4. Lower Risk of Renal involvement
- Improves renal perfusion, decreasing the risk of kidney failure.
- Pharmacologic therapy alone may worsen renal function due to excessive diuresis.
-
5. Better Nutritional Status and Quality of Life
- Reduces abdominal distension and discomfort from ascites.
- Improves appetite, mobility, and exercise tolerance.
-
6. Potential Survival Benefit
- In selected patients, TIPS may offer long-term survival advantages.
- More effective than drugs alone in severe portal hypertension cases.
What to Expect After the Procedure:
Immediate Self-Care in the Hospital After a TIPS Procedure
- 1. Rest in Bed: Stay under observation while your body begins to recover.
- 2. Vital Monitoring: Nurses and doctors will check your blood pressure, heart rate, and oxygen levels frequently. Any increase of fall in BP is immediately addressed. Report any breathing difficulty
- 3. Pain Management: Inform staff about any pain or discomfort; medications will be provided if needed.
- 4. Monitoring Fluid intake and output: Adequate urine output
- 5. Dietary Guidance: You'll start with fluids or a soft diet, transitioning to regular meals based on your recovery. Most patients are able to start taking oral fluids by four hours and soft diet by -------
- 6. Prevent Infections: Medical staff will maintain sterile conditions; notify them of any fever or chills.
- 7. Medication Administration:
- 8. Education for Discharge: Staff will provide instructions on managing symptoms, medications, and follow-up care before you leave
- 9. Recovery: Most patients recover in the hospital in a few days, with follow-up imaging to check the shunt's patency.
- 10. Monitoring for complications: Look for fever, bleeding, liver function, heart function, kidney function.

Liver Transplantation
Liver transplantation is a surgical procedure in which a diseased or failing liver is replaced with a healthy liver from a donor. It is considered the definitive treatment for patients with end-stage liver disease, acute liver failure, or certain liver cancers when other therapies are no longer effective.
Indications for Liver Transplantation
- End-stage liver disease (decompensated cirrhosis with complications such as ascites, variceal bleeding, hepatic encephalopathy, or jaundice).
- Acute liver failure (e.g., from viral hepatitis, drug toxicity such as acetaminophen overdose).
- Hepatocellular carcinoma (HCC) within transplant criteria (e.g., Milan criteria).
Procedure Overview
- Performed under general anesthesia in a specialized transplant center.
- The diseased liver is surgically removed and replaced with a donor liver (either from a deceased donor or a living donor).
- Blood vessels and bile ducts are reconnected to restore liver function.
- Surgery typically takes 6–12 hours, followed by intensive care monitoring.
Preparation for Liver Transplantation
-
1. Comprehensive Medical Evaluation
- Assessment of liver function, kidney function, heart and lung status.
- Screening for infections, cancers, and overall physical fitness.
-
2. Psychological and Social Evaluation
- Assessing patient’s ability to adhere to post-transplant medications and follow-up.
- Evaluating social support and lifestyle factors (e.g., alcohol abstinence).
-
3. Placement on the Transplant Waiting List
- Patients are listed based on MELD score (Model for End-Stage Liver Disease), which prioritizes the sickest patients.
-
4. Informed Consent and Patient Education
- Discussion of risks, benefits, and lifelong commitment to medical care after transplantation.
Benefits of Liver Transplantation
-
1. Definitive Treatment for Liver Failure
- Restores normal liver function and resolves life-threatening complications.
-
2. Improved Survival
- Many patients experience long-term survival with good quality of life after transplant.
-
3. Potential for Cure
- For some conditions (e.g., acute liver failure, metabolic disorders), transplantation offers a complete cure.
Risks of Liver Transplantation
- Surgical Risks: bleeding, infection, bile duct complications.
- Rejection: the immune system may attack the new liver, requiring immunosuppressive therapy.
- Infections: immunosuppressants increase susceptibility to infections.
- Side Effects of Long-Term Medications: weight gain, high blood pressure, diabetes, kidney problems.
- Cancer Risk: higher risk of certain cancers due to immunosuppression.
Lifestyle and Self-Management After Transplantation
