What Is Hepatitis: Know Symptoms and Causes

Hepatitis is an inflammation of the liver that can have various causes, including viral infections, alcohol consumption, or autoimmune diseases. The symptoms of hepatitis can vary depending on the cause and the stage of the disease. Let’s explore what is hepatitis, its symptoms, causes with types and related faqs.

What is Hepatitis?

Hepatitis is a sickness that makes your liver swell up and not work right. Your liver is an important part of your body that helps with digestion and cleaning your blood. Hepatitis can happen because of germs (viruses), too much drinking, or some medicines.

It can make you feel tired, sick to your stomach, and your skin and eyes might turn yellow. Some types of hepatitis can go away on their own, but others need special treatment. It’s important to protect your liver and take care of it to stay healthy.

Symptoms of Hepatitis

Let’s delve into more detail about the common symptoms of hepatitis:

1. Jaundice

Jaundice is a yellowing of the skin, eyes, and mucous membranes. It occurs when the liver is unable to process bilirubin, a yellow pigment produced when red blood cells break down.

In hepatitis, liver inflammation or damage can impair the liver’s ability to metabolize bilirubin, leading to its accumulation in the bloodstream. This buildup causes the characteristic yellow discoloration.

2. Fatigue

Hepatitis can lead to extreme tiredness and fatigue, which can be debilitating. This fatigue is often a result of the body’s immune response to the infection, as well as the liver’s decreased ability to store and release energy.

3. Abdominal Pain

Hepatitis-related abdominal pain typically manifests as a dull ache or discomfort in the upper right side of the abdomen, where the liver is located. The pain can vary in intensity and may be caused by liver inflammation, stretching of the liver capsule, or other related factors.

4. Loss of Appetite

Hepatitis can cause a loss of appetite, which can lead to reduced food intake and subsequent weight loss. This is partly due to the overall feeling of malaise and discomfort associated with the disease.

5. Nausea and Vomiting

Nausea and vomiting are common symptoms of hepatitis. The inflammation in the liver can affect the digestive system, leading to feelings of nausea and, in some cases, vomiting. These symptoms can contribute to a further loss of appetite.

6. Dark Urine

Hepatitis can cause urine to become dark in color, often resembling the color of tea. This darkening occurs because the liver’s impaired function leads to the accumulation of bilirubin in the urine.

7. Pale Stools

Stools may become lighter in color or clay-colored in hepatitis. This change occurs because bilirubin, which gives stool its characteristic brown color, is not properly processed and excreted by the liver.

8. Fever

A low-grade fever is a common symptom of acute hepatitis, especially when it is caused by a viral infection. The fever is a sign of the body’s immune response to the virus.

9. Muscle and Joint Pain

Some individuals with hepatitis may experience muscle and joint aches, similar to flu-like symptoms. These discomforts can be attributed to the body’s immune response to the infection.

10. Itchy Skin

Itchy skin, known as pruritus, can be a symptom of certain types of hepatitis, particularly cholestatic hepatitis. Cholestatic hepatitis is characterized by impaired bile flow, which can lead to the buildup of bile salts in the bloodstream, causing itching.

These symptoms can vary widely among individuals with hepatitis. Some may have only a few mild symptoms, while others may experience more severe.

Causes of Hepatitis

Hepatitis can have various causes, and it is typically classified into several types, each associated with different causes. The most common types of hepatitis are hepatitis A, B, C, D, and E. Here are the primary causes of these hepatitis types:

1. Hepatitis A (HAV)

• Cause: Hepatitis A is caused by the hepatitis A virus (HAV). It is typically contracted by consuming contaminated food or water or through close contact with an infected person.
• Transmission: HAV is transmitted through the fecal-oral route, which means that the virus is present in the feces of infected individuals and can be spread when people ingest contaminated food or water.

2. Hepatitis B (HBV)

• Cause: Hepatitis B is caused by the hepatitis B virus (HBV). It can be transmitted through contact with infected blood, semen, or other bodily fluids.
• Transmission: HBV can be transmitted through unprotected sexual contact, sharing needles or syringes, from an infected mother to her child during childbirth, and through close household contact with an infected person.

3. Hepatitis C (HCV)

• Cause: Hepatitis C is caused by the hepatitis C virus (HCV). It is primarily spread through contact with infected blood, making it a common concern for individuals who use intravenous drugs or receive blood transfusions or organ transplants.
• Transmission: HCV can be transmitted through sharing needles, receiving blood products before 1992 (when blood screening became more stringent), and, in rare cases, through sexual contact or from an infected mother to her child during childbirth.

4. Hepatitis D (HDV)

• Cause: Hepatitis D, also known as delta hepatitis, is caused by the hepatitis D virus (HDV). HDV is unique in that it can only infect individuals who are already infected with hepatitis B.
• Transmission: HDV is primarily transmitted through contact with infected blood or other bodily fluids, similar to HBV. It often co-infects or superinfects individuals with existing HBV infections.

5. Hepatitis E (HEV)

• Cause: Hepatitis E is caused by the hepatitis E virus (HEV). It is most commonly associated with contaminated water supplies and is a significant cause of hepatitis in developing countries.
• Transmission: HEV is transmitted through the fecal-oral route, similar to HAV, and is typically linked to poor sanitation and hygiene practices.

In addition to these viral causes of hepatitis, there are other non-viral causes, including:

• Autoimmune Hepatitis: This occurs when the body’s immune system mistakenly attacks the liver, leading to inflammation and liver damage.
• Alcohol: Excessive alcohol consumption over a prolonged period can lead to alcoholic hepatitis, which can cause liver inflammation and damage.
• Toxic Substances: Exposure to certain toxic substances, such as chemicals and medications, can result in drug-induced hepatitis.

It’s important to note that prevention and management strategies can vary depending on the type and cause of hepatitis. Vaccination is available for hepatitis A and hepatitis B, which can help prevent these infections.

Additionally, effective treatments and antiviral medications are available for hepatitis B and C, but not for hepatitis A and E, which are typically self-limiting and resolve on their own with time. Autoimmune hepatitis may require immunosuppressive medications, and alcoholic hepatitis necessitates alcohol cessation and supportive care.
