From: MedlinePlus, National Library of Medicine

Hepatitis A is a type of viral hepatitis. It causes an acute, or short-term, infection. This means that people usually get better without treatment after a few weeks.

Thanks to a vaccine, hepatitis A is not very common in the United States.

What causes hepatitis A?

From: MedlinePlus, National Library of Medicine

Hepatitis A is caused by the hepatitis A virus. The virus spreads through contact with an infected person's stool. This can happen if you:

• Eat food made by someone who has the virus and did not properly wash their hands after using the bathroom
• Drink contaminated water or eat foods that were rinsed with contaminated water
• Have close personal contact with someone who has hepatitis A. This could be through certain types of sex (like oral-anal sex), taking care of someone who is ill, or using illegal drugs with others.

Who is at risk for hepatitis A?

From: MedlinePlus, National Library of Medicine

Although anyone can get hepatitis A, you are at higher risk if you:

• Travel to developing countries
• Have sex with someone who has hepatitis A
• Are a man who has sex with men
• Use illegal drugs
• Are experiencing homelessness
• Live with or care for someone who has hepatitis A
• Live with or care for a child recently adopted from a country where hepatitis A is common

What are the symptoms of hepatitis A?

From: MedlinePlus, National Library of Medicine

Not everyone with hepatitis A has symptoms. Adults are more likely to have symptoms than children. If you do have symptoms, they usually start 2 to 7 weeks after infection. They can include:

• Dark yellow urine
• Diarrhea
• Fatigue
• Fever
• Gray- or clay-colored stools
• Joint pain
• Loss of appetite
• Nausea and/or vomiting
• Abdominal pain
• Yellowish eyes and skin, called jaundice

The symptoms usually last less than 2 months, although some people can be ill for as long as 6 months.

You are at a higher risk of getting a more severe infection from hepatitis A if you also have HIV, hepatitis B, or hepatitis C.

What other problems can hepatitis A cause?

From: MedlinePlus, National Library of Medicine

In rare cases, hepatitis A may lead to liver failure. This is more common in adults over age 50 and in people who have another liver.

How is hepatitis A diagnosed?

From: MedlinePlus, National Library of Medicine

To diagnose hepatitis A, your health care provider may use many tools:

• A medical history, which includes asking about your symptoms
• A physical exam
• Blood tests, including tests for viral hepatitis

What are the treatments for hepatitis A?

From: MedlinePlus, National Library of Medicine

There is no specific treatment for hepatitis A. The best way to recover is to rest, drink plenty of liquids, and eat healthy foods. Your provider may also suggest medicines to help relieve symptoms. In more severe cases, you may need care in a hospital.

Can hepatitis A be prevented?

From: MedlinePlus, National Library of Medicine

The best way to prevent hepatitis A is to get the hepatitis A vaccine. It is also important to have good hygiene, especially washing your hands thoroughly after you go to the bathroom.

Understanding terms used in the source

These definitions explain medical words used above. A definition is not evidence that another condition is present, and it does not predict how a symptom will develop. Ask the clinician which terms apply to the actual examination or test result.

Severe infection

A type of infection that is regarded as a sign of a pathological susceptibility to infection because of unusual severity or intensity of the infection.

Abdominal pain

An unpleasant sensation characterized by physical discomfort (such as pricking, throbbing, or aching) and perceived to originate in the abdomen.

Diarrhea

Abnormally increased frequency (usually defined as three or more) loose or watery bowel movements a day.

Jaundice

Yellow pigmentation of the skin due to bilirubin, which in turn is the result of increased bilirubin concentration in the bloodstream.

Vomiting

Forceful ejection of the contents of the stomach through the mouth by means of a series of involuntary spasmic contractions.

Which doctor should you see?

The suggested department for discussing Hepatitis A is Hepatology, with a hepatologist / gastroenterologist as the relevant type of clinician. General physician / Family Medicine; paediatrician for children. Referral depends on symptoms.

This is an editorial referral starting point. The appropriate clinic depends on the person’s age, symptoms, previous diagnosis and local services. The first clinician can decide whether another specialty or a team is needed; a department label does not confirm the diagnosis.

How to prepare for an assessment

Bring a short timeline of the main symptoms: when they first appeared, whether they are constant or episodic, what seems to change them, and how they affect daily activities. Include previous reports, discharge summaries, current medicines and supplements, allergies, and any relevant family history. A dated record is more useful than trying to match every feature in an online article.

Ask the clinician what is already established and what remains uncertain. If a test is suggested, ask what question it answers, what its limitations are and how the result would change the next step. The information here is not an instruction to arrange every possible test. In children, bring growth, developmental and school information if it is relevant to the concern.

• What is known about the cause and extent of liver involvement?
• Which medicines, supplements or exposures should be reviewed?
• What follow-up is appropriate for the specific diagnosis and stage?

Treatment discussions and follow-up

Where the source describes treatments, these are an overview of possible care, not a prescription for an individual. Ask which option applies to the confirmed diagnosis, what benefit is expected, what adverse effects to watch for and how progress will be assessed. Availability, approvals and local practice can differ from the country described in the source.

Before leaving the appointment, clarify the next review date, who will communicate results, and whom to contact if the situation changes. Discuss difficulties with sleep, work, school, mobility, eating or emotional wellbeing when these are relevant. Practical support may require coordination between the treating clinician and other services.

When to seek emergency help

Severe breathing difficulty, collapse, new stroke-like symptoms, a seizure that is prolonged or repeated without recovery, uncontrolled major bleeding, or an immediate risk of self-harm require emergency help. In India, call 112 or reach the nearest emergency department. This is a general, non-exhaustive warning list; it is not a condition-specific triage tool.
