Hepatitis: Types, Symptoms, Causes, Treatment & Prevention

When it comes to liver health, we often do not pay it much attention and only worry about it when something goes wrong. If you or someone you know has just been diagnosed with hepatitis or just wants to learn more about the disease, then you're in the right place. Hepatitis is one of the most prevalent and misinterpreted liver diseases in the world, and understanding the facts can save lives.

In the gastroenterology and liver unit at Mahatma Gandhi Hospital, our liver doctors and hepatologists treat patients with hepatitis every day. This guide contains all the information you need to know about hepatitis disease, including what it is and how it is diagnosed, treated, and prevented. If you have concerns about the symptoms of hepatitis, or you're concerned about a family member having hepatitis, you might be wondering about the hepatitis vaccine, or you might be asking if hepatitis can be cured; read on.

What Is Hepatitis?

So, what is hepatitis, exactly? Hepatitis basically means inflammation of the liver. The term itself is derived from the Greek words "hepar," meaning "liver," and "itis," meaning "inflammation. An inflamed liver cannot perform its normal functions, which include filtering out toxins from the blood, making bile for food digestion, storing energy, and helping the immune system.

What is hepatitis in a broader sense? It can sometimes last for a short period of time and be mild, or it may be a chronic, long-term condition that may result in other serious complications such as liver failure or liver cancer. It occurs in people of all ages, backgrounds, and walks of life and is much more prevalent than most people imagine.

The WHO estimates more than 300 million people worldwide are infected with both chronic hepatitis B and C. Viral hepatitis is one of the main causes of liver disease in India, and the burden of hepatitis is more significant in India than in any other country.

Types of Hepatitis

The first thing to note is that there are different types of hepatitis, and they act very differently. Let's dive in and see what the most common and leading types and causes of hepatitis are.

Viral Hepatitis (Types A, B, C, D and E)

Viral hepatitis is the result of infection by a family of viruses that specifically affect the liver. There are 5 main hepatitis viruses called A, B, C, D, and E, which each have their own ways of transmission, severity, and approach to their treatment.

Hepatitis A virus (HAV) causes the disease and is usually transmitted by contaminated food and water. It has been classified as an acute hepatitis infection; that is, it typically resolves without long-term consequences within several weeks to months. Common in areas of poor sanitation, and there is a trustworthy hepatitis immunization.

The hepatitis B virus (HBV) causes hepatitis B, which can be transmitted by contact with blood, sexual activity, or from a mother to her child at birth. Can be either acute or chronic. If left untreated, chronic hepatitis B may result in cirrhosis and liver cancer. Thankfully, there is a safe and effective hepatitis injection (vaccine) available that can protect people from getting hepatitis B at all.

Hepatitis C is a viral hepatitis infection caused by HCV, which is usually transmitted through blood-to-blood contact, mainly through the sharing of needles or other drug equipment. There is no vaccine available for hepatitis C, whereas the current antiviral medications have a high success rate for curing hepatitis C.

Hepatitis D is only found in those who also have hepatitis B. Sometimes referred to as a co-infection, it can worsen the disease.

Hepatitis E is like hepatitis A, which is spread by contaminated water. It is generally not severe but can be quite hazardous in pregnant women.

Alcoholic Hepatitis

Alcoholic hepatitis is a direct result of prolonged heavy drinking leading to inflammation of the liver. It's one of the most preventable forms of liver hepatitis, and yet it's shockingly prevalent. The signs and symptoms of alcoholic hepatitis may be vague and may be experienced over a period of time, such as jaundice, abdominal pain, nausea, and confusion. Alcoholic hepatitis can rapidly develop into liver failure in difficult situations.

Total and permanent abstinence from alcohol is the first and foremost treatment of alcoholic hepatitis. If alcoholic hepatitis is severe, hospitalization and specialized medical treatment are necessary. At Mahatma Gandhi Hospital, our team offers you help in a compassionate and evidence-based way and helps you through this difficult time with treatments for alcoholic hepatitis.

Autoimmune Hepatitis

Autoimmune hepatitis is the body's immune system attacking the liver, as if it were an invader. This may lead to considerable damage to the liver and eventual scarring. It's more prevalent in women and needs to be maintained with long-term immunosuppressive treatment.

Drug-Induced and Toxic Hepatitis

The liver's reaction to drugs and poisons. Liver response to medicines and harmful substances.

Some drugs, herbal remedies, and toxic chemicals can lead to liver inflammation. This form of hepatitis is treated by eliminating the source of the problem, but for some, the damage may be extensive.

Hepatitis Symptoms: What Exactly is Hepatitis Like?

This is an important part of this guide, as many people with hepatitis are not ill whatsoever, particularly when they are in the early stages. In particular, viral hepatitis can be silent for several years, and the virus quietly attacks the liver. That's why hepatitis is sometimes referred to as the "silent epidemic.

If the symptoms of hepatitis do occur, the most common are:

Early and common hepatitis symptoms:

• Ongoing tiredness and weakness that doesn't get better when you rest
• Loss of appetite and unexpected weight loss (UWL)
• Nausea and vomiting
• Abdominal pain, which is mild to moderate, particularly in the upper right part of the abdomen where the liver is located
• Low-grade fever
• Aches or pains in the muscles and joints

Signs and symptoms of hepatitis as it progresses:

• Hepatitis A, B, and E or other types of liver failure
• Dark, tea-coloured urine
• Clay-colored or pale stools
• Itchy skin
• Swelling in the abdomen due to fluid build-up (ascites)

If you experience any of these symptoms of hepatitis, please don't delay. Early diagnosis of liver diseases can help a lot, and at Mahatma Gandhi Hospital, we are providing liver function tests and hepatitis screening that will help you get answers promptly!

Causes of Hepatitis: How Do You Get It?

Knowledge of the cause of hepatitis is a good first step toward self- and family protection. There are five types of hepatitis, and they differ in their causes:

Viral causes: Infected blood, sexual contact with an infected person, sharing of needles, contaminated food/water, and mother-to-child transmission at birth.

Alcohol: Heavy consumption over time causes damage to the cells of the liver and leads to inflammation, which results in alcoholic hepatitis.

Medications and Toxins: Overuse of some over-the-counter painkillers (especially paracetamol), prescription drugs, industrial chemicals, and some herbal products.

Autoimmune Response: Immune system attack on liver tissue that has no apparent source.

Non-alcoholic fatty liver disease (NAFLD): When there is an excess of fat in the liver, which may be linked to obesity, type 2 diabetes, and metabolic syndrome, it can cause a type of infection called hepatitis NASH.

Acute Hepatitis vs. Chronic Hepatitis: What is the difference?

Doctors usually speak of hepatitis in terms of length of time.

Acute hepatitis is inflammation of the liver, which occurs for a period of less than six months. Most cases of hepatitis A and hepatitis E infections, as well as most cases of acute hepatitis, are treated with supportive care and rest and will resolve spontaneously. In a few acute cases, however, it may progress to fulminant hepatic failure, a medical emergency.

Chronic hepatitis is when liver inflammation persists for more than six months. The most common causes for chronic hepatitis are hepatitis B, C, and D. If untreated, chronic hepatitis disease can quietly progress over many years to cirrhosis (scarring of the liver) and eventually hepatic failure. For that reason, early screening is important.

Hepatic Encephalopathy: A Serious Complication You Should Know About

Hepatic encephalopathy is a condition that develops due to advanced liver disease and severe hepatitis. If the liver is not functioning properly, the toxins in the blood cannot be filtered out, and this can interfere with the brain's ability to function, particularly ammonia. This results in a range of symptoms from mild confusion and forgetfulness to severe disorientation, personality changes, tremors, extreme cases of loss of consciousness, and coma.

Stages of hepatic encephalopathy are usually defined as mild (Grade 1, subtle personality changes) to moderate (Grade 2, mental slowing) to severe (Grade 4, deep coma). It's important to recognize the early signs, as early treatment can help stop the condition from getting worse and becoming life-threatening.

One of the most severe complications of hepatitis is hepatic failure, which is a medical emergency. Mahatma Gandhi Hospital's specialists can recognize and treat hepatic encephalopathy at any stage.

Complications of Hepatitis: Why Treatment Cannot Wait

If hepatitis is not treated, it can cause a variety of serious and even permanent complications of hepatitis:

• Cirrhosis: The progressive scarring of the liver, which involves the loss of liver function and the replacement of healthy liver tissue.
• Hepatocellular carcinoma of the liver (liver cancer): Special risk due to chronic hepatitis B and C.
• Hepatic failure: If the liver becomes so impaired that it can no longer provide life-sustaining functions.
• Hepatic encephalopathy: As mentioned above, this affects brain function.
• Portal hypertension: The raised pressure in the blood vessels that bring blood to the liver.
• Kidney failure: Sometimes associated with kidney failure.

Fortunately, most of these complications are avoidable if hepatitis is diagnosed and treated early.

Hepatitis Treatment

Treatment for hepatitis varies based on the type, cause, and stage of disease.

• Hepatitis A Treatment: No specific antiviral treatments are available. Usually, rest, fluids, and avoiding alcohol and some drugs are enough. Most people make a full recovery in 2-4 months.
• Hepatitis B Treatment: Most people with acute hepatitis B recover spontaneously. Chronic hepatitis B is treated with drugs such as tenofovir or entecavir, which inhibit hepatitis B and help to prevent liver damage. Hepatitis B is not always a disease that can be cured, but it can be well controlled.
• Hepatitis C Treatment: One of the great medical success stories of the last few decades. Direct-acting antiviral agents are available that can cure hepatitis C in more than 95% of patients in 8 to 12 weeks. In the search for a cure for hepatitis, the most significant advances in medicine have occurred with hepatitis C. Many also wonder, is there a more general cure for hepatitis? It all depends on the type, but results have never been more positive.

The most crucial measure in alcohol-related hepatitis treatment is to stop drinking alcohol. Alcoholic hepatitis treatment includes nutritional support, corticosteroids, and, if necessary, hospitalization with intensive medical care.

• Autoimmune hepatitis treatment: Corticosteroids (such as prednisolone) and immunosuppressants (such as azathioprine) are used to reduce the immune response, which is long-term.
• Hepatic encephalopathy treatment: Lactulose to decrease ammonia absorption, dietary protein control, treatment of underlying causes, and rifaximin antibiotics for recurrent cases.

Liver transplantation might be a life-saving option in more severe instances when the liver damage is extensive.

Hepatitis Vaccine: Your Best Defence

When it comes to prevention versus cure, there's no better public health tool than the hepatitis vaccine.

• Hepatitis A vaccine: Very effective, two doses 6 months apart, recommended for children, travelers, and high-risk situations.
• Hepatitis B vaccine: Offered in three doses (see the hepatitis vaccination schedule), it is usually given from birth onwards. This is a combination vaccine against hepatitis B (HBV) and hepatitis D (HDV).

Currently, there is no approved vaccine for any of these types of hepatitis, except for hepatitis B, and so it is especially important to avoid risk factors for these types.

Hepatitis Prevention: Practical Tips You Can Take Today

Hepatitis prevention is 100% possible as long as the right habits and awareness are followed. These are the key steps to hepatitis prevention:

For viral hepatitis:

• Ensure appropriate immunisation against Hepatitis A and B (if not already immunised)
• Always practice safe sex and use protection.
• Never share needles/syringes or any personal items that might be contaminated with blood.
• Wash hands properly before preparing/consuming food and after using the toilet.
• Use only clean, safe water, particularly when traveling.
• Avoid tattoos and piercings and use sterile equipment.

For alcoholic hepatitis:

• Drink within the recommended limits for alcohol.
• If you have a drinking problem, don't hesitate to get assistance early.

For drug-induced hepatitis:

• Never give more than the recommended amount of any medicine!
• Let your doctor know what you're taking, including medication, supplements, and herbal or natural products.
• If taking medication for a long period of time, have regular liver function tests.

For all types:

• See regular health checks, particularly if there are any health risk factors.
• If pregnant, test for Hepatitis B, as the baby can catch this virus at birth if the mother is infected.

Hepatitis Diet Chart: The Food to Take for the Health of Your Liver!

Food actually affects the liver, particularly for those who have or are recovering from hepatitis. With proper design, a hepatitis diet plan can help to minimize inflammation, assist in healing the liver, and prevent complications.

Here are some foods to add to a diet with hepatitis:

• Lots of fresh fruits and vegetables, particularly leafy greens, berries, and cruciferous vegetables such as broccoli and cauliflower.
• Whole grain products like whole grain breads, whole grain crackers, oats, brown rice, and whole grain cereals.
• Lean proteins like chicken, fish, eggs, and legumes.
• Methods to manage heat loss, such as drinking extra fluids or taking a cold pack to help the body cool down. How to prevent heat loss: drink extra fluids or carry a cold pack to help cool the body.
• Garlic and turmeric that have natural anti-inflammatory properties.

Foods and drinks that should be avoided:

• Even though you have active hepatitis, do not drink alcohol, even in small amounts!
• Foods that are high in fat and fried.
• Convenience foods with added sodium and other ingredients that are processed and packaged.
• Raw shellfish, particularly shellfish contaminated with hepatitis A or E.
• Too much sugar and refined carbs.
• Iron supplements (except as prescribed), as excessive iron can aggravate liver inflammation.

If you have been diagnosed with hepatitis, consult with your doctor or clinical dietitian to create a personalized diet plan for your disease type and stage. We can refer you to nutritional support as part of your care at Mahatma Gandhi Hospital.
