Hepatitis: Types, Symptoms, Causes

Hepatitis is an inflammation of the liver, an essential organ involved in many vital processes, including protein synthesis, detoxification, and the synthesis of biochemicals required for digestion. Numerous things can cause this inflammation, which can result in various types of hepatitis.

Infectious and non-infectious agents can cause hepatitis. The most prevalent cause of hepatitis is viral infections, but it can also result from other causes such as toxins, alcohol misuse, autoimmune disorders, and certain medications.

It is essential to learn about hepatitis to prevent and treat it effectively. Even those who are impacted by this disease can lead healthy lives with the right information and medical attention. In this article, we will talk about the different types, symptoms, and underlying causes of hepatitis.

Types of Hepatitis

There are five primary types of hepatitis, each caused by a different virus:

Hepatitis A

The Hepatitis A virus (HAV) is the cause of the highly contagious liver infection known as hepatitis A. It is more prevalent in areas with inadequate sanitation because it is mainly transmitted by the consumption of food or water polluted with waste products from an infected individual. The symptoms include fatigue, nausea, vomiting, abdominal pain, appetite loss, low-grade fever, dark urine, pale stool, and jaundice.

Hepatitis A, compared to other forms, does not result in chronic liver disease and frequently goes away on its own with supportive care, such as rest and enough food and fluid intake.  For adults and children at high risk, the Hepatitis A vaccine is highly recommended as it effectively lowers the infection’s impact and growth.

Hepatitis B

The Hepatitis B virus (HBV) causes a dangerous liver infection known as hepatitis B. It is spread by coming into contact with infectious bodily fluids, like blood, semen, and vaginal secretions. It can be transmitted through sharing needles, sexuality, or mother-to-child transmission during childbirth. 

Hepatitis B symptoms can vary in severity and include jaundice, dark urine, pale stool, fatigue, fever, nausea, and vomiting, along with abdominal pain. Some people recover from the infection quickly, but others get chronic Hepatitis B, which can cause serious liver problems like liver cancer and cirrhosis.

Hepatitis C

Hepatitis C is caused due to the Hepatitis C virus (HCV). It mainly spreads through blood contact, often through sharing needles or other injecting equipment. It can also be passed from mother to child during childbirth, through sexual contact, and through organ transplants and blood donations. 

It can take decades for many people with Hepatitis C to show symptoms before there is serious liver damage. Fatigue, fever, nausea, abdominal pain, dark urine, pale stool, and jaundice are some of the symptoms that may appear. Severe liver disorders like cirrhosis, liver cancer, and liver failure can result from chronic Hepatitis C.

Hepatitis D

Hepatitis D, also called delta hepatitis, is caused by the Hepatitis D virus (HDV). As opposed to other forms of hepatitis, the Hepatitis D virus (HDV) requires the presence of the Hepatitis B virus (HBV) to replicate. As a result, it can only spread to people who already have HBV. 

Like HBV, transmission happens through sharing surgical instruments., but it also occurs through contact with infected blood or other parts of the body. 

Hepatitis D can cause symptoms such as fatigue, jaundice, abdominal pain, nausea, and vomiting, which are similar to those of hepatitis B. On the other hand, HDV infection is frequently more severe and can increase the risk of cirrhosis and liver failure.

Hepatitis E

The liver infection Hepatitis E is caused by the Hepatitis E virus (HEV). It is primarily spread by contaminated food or water consumption, especially in areas with inadequate sanitation. 

Direct contact with an infected person’s excrement can also spread it. Hepatitis E infections are most prevalent in developing nations with poor access to sanitary facilities and clean water. Like other forms of hepatitis, hepatitis E can cause fatigue, nausea, vomiting, abdominal pain, fever, dark urine, pale stools, and jaundice. 

Hepatitis E can cause severe consequences in pregnant women, such as liver failure and even death.

Symptoms of Hepatitis

The common symptoms of hepatitis may include:


Hepatitis often manifests as extreme fatigue and low energy, which can have a major negative influence on everyday activities and quality of life. It could be extremely exhausting, making it difficult to perform daily duties or engage in activities.


Jaundice, or the yellowing of the skin and eyes, is a well-known sign of hepatitis. This yellow discolouration is caused by high blood bilirubin levels, which are created when red blood cells break down.

Abdominal Pain

Hepatitis can cause pain or discomfort in the liver, which is located in the upper right side of the abdomen. This pain in the stomach can be intermittent or continuous, and its intensity can range from minor discomfort to severe cramps.

Nausea and Vomiting

Hepatitis usually gives rise to digestive symptoms like nausea and vomiting, especially after eating or when the liver is under stress. These symptoms can be annoying and may be a factor in continued reduced appetite and weight loss.

Dark Urine

Urine that is darkened, from amber to brownish, is a concerning sign of hepatitis. Increased blood levels of bilirubin, which is released by the kidneys into the urine, cause this discolouration. When the liver cannot properly eliminate bilirubin, it builds up in the body and gives urine a dark colour.

Pale Stools

Hepatitis is also identified by the lightning of the stools, which can have a clay-like or pale appearance. The change in the colour of stool is caused by the liver’s decreased bile production.

Joint Pain

Hepatitis can result in joint pain and discomfort, which frequently resembles arthritis-like symptoms. Arthritis is a term for this type of joint pain that can range in intensity from minor to fatal and affect several joints in the body.

Causes of Hepatitis

The causes of hepatitis include:

Alcohol Misuse

Alcoholic hepatitis is a condition identified by inflammation and liver damage caused by excessive alcohol consumption. Increased alcohol consumption can raise the risk of liver cancer and cause liver cirrhosis.


Hepatitis can also result from exposure to specific toxins, including pharmaceuticals, industrial chemicals, and environmental pollutants, which can harm the liver. Aflatoxin exposure from tainted food, acetaminophen overdose, and carbon tetrachloride exposure are a few examples.


Drug-induced hepatitis is an adverse effect of some medications, especially those that are metabolised by the liver. Over-the-counter drugs, prescription medications, and herbal supplements can cause this issue.

Autoimmune Diseases

The immune system of the body accidentally targets the liver in autoimmune hepatitis, causing inflammation and liver damage. Although the precise cause of autoimmune hepatitis is unknown, a combination of immunological, environmental, and genetic factors are probably involved.


In conclusion, a variety of hepatitis types, symptoms, and causes make it an extremely dangerous disease. Preventive measures and vaccinations are crucial in reducing the risk of infection, so their significance cannot be emphasised enough. With immediate interventions, hepatitis patients can effectively manage their disease and prevent the development of long-term destructive complications, protecting their general health and well-being.
