This test is used for people of any age who may have liver problems or need to monitor known liver conditions.

When to see a doctor

See a doctor urgently if:

• If you have any of the emergency symptoms listed above, call your local emergency number right away.

Book a routine appointment if:

• If you experience ongoing symptoms like fatigue, mild jaundice, or discomfort in your belly area, make an appointment with your healthcare provider to discuss whether a liver ultrasound is appropriate.

Diagnosis

Your doctor will first review your symptoms and medical history. If they suspect a liver problem, they may order a liver ultrasound as the first imaging test.

Tests that may be done

• Liver ultrasound
• Blood tests to check liver function
• Sometimes a CT scan or MRI if the ultrasound shows something unusual

What to expect at your appointment

During the ultrasound, you will lie on an exam table. A specially trained technician (sonographer) will apply a clear gel to your abdomen and move a small handheld device (transducer) over your skin. The device sends sound waves that create pictures of your liver on a screen. You may be asked to hold your breath for a few seconds. The test is painless and takes about 30 to 60 minutes. You can go home right after and continue normal activities.

Treatment

Treatment depends on what the ultrasound finds. If the liver appears healthy, no treatment is needed. If there is a condition, your doctor will discuss the best plan for you, which may include lifestyle changes, medications, or further tests.

Self-care at home

• Limit or avoid alcohol
• Eat a healthy diet low in fat and sugar
• Exercise regularly to maintain a healthy weight
• Follow your doctor’s advice about any medicines you take

Medical treatments

Depending on the diagnosis, your doctor may prescribe medicines to treat infections like viral hepatitis, reduce inflammation, or manage complications. Always take medications exactly as prescribed and discuss any side effects with your doctor.

When is surgery considered?

Surgery might be needed for certain conditions found on ultrasound, such as large liver cysts, benign tumors that cause symptoms, or for liver cancer. In severe cases, a liver transplant may be considered. Your healthcare team will explain all options if surgery is a possibility.

Living with this condition

If a liver condition is found, you will likely need regular follow-ups, including repeat ultrasounds and blood tests, to monitor your liver health. Staying informed and working with your healthcare team is key.

Lifestyle tips

• Avoid alcohol completely if you have liver disease
• Maintain a healthy weight through diet and exercise
• Get vaccinated against hepatitis A and B if recommended
• Be careful with over-the-counter medications; always check with your pharmacist or doctor

Diet and exercise

A balanced diet rich in fruits, vegetables, whole grains, and lean protein supports liver health. Limit sugary drinks and fatty foods. Physical activity such as walking for 30 minutes most days helps maintain a healthy weight and reduces liver fat.

Mental health and emotional wellbeing

Living with a liver condition can cause worry or stress. It is important to talk about your feelings with family, friends, or a mental health professional. Remember, you are not alone, and support is available.

Prevention

You can reduce your risk of liver problems by avoiding heavy alcohol use, maintaining a healthy weight, getting vaccinated against hepatitis B, and practicing safe behavior to avoid viral hepatitis.

Vaccines

Vaccines are available for hepatitis A and hepatitis B. Ask your doctor if they are right for you.

Screening programmes

If you are at high risk for liver disease (for example, due to family history or chronic viral hepatitis), your doctor may recommend regular ultrasounds and blood tests to catch problems early.

Complications

If left untreated

• Chronic liver disease can lead to cirrhosis (scarring of the liver)
• Liver failure (when the liver stops working properly)
• Increased risk of liver cancer
• Serious bleeding from enlarged veins in the esophagus (varices)

Long-term outlook

If a liver condition is found early, there are many effective treatments available. Even for more advanced disease, medical care can help manage symptoms and improve quality of life. Always follow your healthcare provider’s advice for the best outcome.
