Types of Hepatitis

Hepatitis caused by viruses comes in five different forms. Hepatitis A, Hepatitis B, Hepatitis C, Hepatitis D, and Hepatitis E are the five types of hepatitis. Hepatitis A is always an acute, short-term infection, whereas hepatitis B, C, and D have a higher chance of becoming chronic and persistent. 

Hepatitis A

An infection with the hepatitis A virus causes hepatitis A. (HAV). Eating or drinking food or water contaminated with hepatitis A-infected faeces is the most prevalent way to develop this type of hepatitis.

Hepatitis A

Hepatitis B

Hepatitis B is a liver disease-causing virus. Hepatitis B is transferred through contact with infectious body fluids such as blood, vaginal secretions, or sperm that contain the hepatitis B virus (HBV). Injecting narcotics, having sex with an infected partner, or sharing razors with an infected person are all ways to transfer hepatitis B.

Hepatitis B

Hepatitis C

Hepatitis C

Hepatitis C is spread through direct contact with tainted bodily fluids, such as injectable drugs and sexual interaction.

Hepatitis D

Hepatitis D

The hepatitis D virus causes hepatitis D, often known as delta hepatitis, a life-threatening liver disease (HDV). Coming into contact with infected blood spreads HDV. Hepatitis D is a rare kind of hepatitis that exclusively occurs in the presence of hepatitis B. Hepatitis D cannot spread unless hepatitis B is also present.

Hepatitis E

The hepatitis E virus causes hepatitis E, which is a liver infection. Hepatitis E is primarily spread through feces-contaminated water. Jaundice, a loss of appetite, and nausea are some of the symptoms. In rarest of rare cases it can lead to liver failure. Hepatitis E usually clears up in four to six weeks on its own. Supportive care, rehydration, and rest are the mainstays of treatment.

Toxins 

Excessive alcohol use can harm and inflame the liver. Alcoholic hepatitis is the medical term for this illness. The alcohol damages your liver cells immediately. Over time, it can cause liver failure and cirrhosis, which is the thickening and scarring of the liver. Overuse or overdose of drugs, as well as exposure to chemicals, are other hazardous causes of hepatitis.

Response of the Autoimmune System

In rare situations, the immune system misidentifies the liver as a threat and attacks it.It causes chronic inflammation that can range from mild to severe, and in many cases, it impairs liver function. Women are more prone to this than men.

Symptoms of Hepatitis

[Click Here for Sample Questions]

If you have chronic infectious hepatitis, such as hepatitis B or C, you may not notice any symptoms at first. It's possible that symptoms won't show up until the damage has a negative impact on liver function.

Acute hepatitis symptoms and signs arise quickly. They are as follows:

• flu-like symptoms fatigue
• abdominal pain, dark urine, pale stool
• Jaundice symptoms include a loss of appetite, unexplained weight loss, and yellow skin and eyes.
• Because chronic hepatitis progresses slowly, these signs and symptoms may go unnoticed.

Prevention of Hepatitis

Hepatitis can be prevented in two ways they are as follows:

Hygiene

The most important way to avoid the disease of Hepatitis A and E is that one should maintain absolute hygiene. One should avoid the following when visiting a developing country:

• Ice
• Shellfish and oysters that are uncooked or undercooked
• Raw fruits and vegetables.

Hepatitis B, C, and D, which is transmitted through the contaminated blood, the following precautions must be taken in order to avoid the disease:

• not sharing needles for drugs
• not sharing razors
• not using another person's toothbrush
• avoiding coming into contact with blood that has already been spilt

Vaccines

The utilization of immunizations is a significant key to forestalling hepatitis. Immunizations are accessible to forestall the improvement of hepatitis A and B. Specialists are right now creating immunizations against hepatitis C.

Treatment of Hepatitis

Hepatitis A

Since hepatitis A is a short-term infection, it usually does not necessitate treatment. If your symptoms are causing you a lot of pain, bed rest may be prescribed. If you have vomiting or diarrhoea, follow your doctor's hydration and nutrition recommendations. The hepatitis A vaccine can help avoid this infection.

Hepatitis B

For chronic Hepatitis B antiviral medications are recommended for the treatment.

Because this type of treatment must be continued for several months or years, it can be pricey. Regular medical tests and monitoring are also required for chronic hepatitis B treatment to determine if the virus is responding to treatment. Vaccination helps in the treatment of Hepatitis B.

Hepatitis C

Hepatitis C is treated with antiviral medicines in both acute and chronic forms. Chronic hepatitis C is often treated with a combination of antiviral medicines.. They may also require more tests to decide the best course of action. People who develop cirrhosis (liver scarring) or liver disease as a result of chronic hepatitis C may be candidates for a liver transplant.

Hepatitis D

Hepatitis D can be avoided by having the hepatitis B vaccine, as infection with hepatitis B is required for the development of hepatitis D.

Hepatitis E

Hepatitis E is currently treated with no specific medicinal therapy. Because it is so common, the ailment normally fades away on its own. When dealing with this type of infection, it's common advice to get plenty of rest, drink lots of fluids, eat plenty of nutritious foods, and avoid alcohol.
