Fatty liver disease: causes, diagnosis, treatment and what to do next

Fatty liver disease is a common but often silent condition in which excess fat builds up in the liver. I will explain what it is, who is at risk, how it is diagnosed, and practical steps you can take to prevent or reverse it. If you suspect you have fatty liver disease, this article will help you understand next steps and when to get an ultrasound or specialist referral.

What is fatty liver disease and why it matters

Fatty liver disease describes the accumulation of fat inside liver cells. In many people this causes no symptoms, but if fat triggers inflammation it can progress to scarring (fibrosis) and, over years, to cirrhosis or liver failure. The term covers a spectrum from simple fat without damage to metabolic-associated steatotic liver disease with inflammation.

Early detection matters because lifestyle changes can stop or reverse the process before serious damage occurs. Identifying fatty liver disease also highlights broader health risks such as type 2 diabetes, high blood pressure, and heart disease.

Common causes and risk factors

Fatty liver disease most often results from metabolic factors rather than alcohol. Key risk factors include:

  • Overweight and obesity. Excess body fat, especially around the waist, increases liver fat.
  • Type 2 diabetes and insulin resistance. These impair fat handling and raise liver fat levels.
  • High cholesterol and high triglycerides. Abnormal blood lipids promote liver fat storage.
  • Metabolic syndrome. A combination of elevated blood sugar, blood pressure, lipids, and abdominal obesity.
  • Certain medications and rapid weight loss. Some drugs and extreme dieting can worsen liver fat.

Alcohol can cause a separate but related condition. If alcohol intake is modest and metabolic risk factors are present, the diagnosis is commonly metabolic fatty liver disease.

Symptoms and signs to watch for

Many people with fatty liver disease have no symptoms. When symptoms occur they are often vague, such as:

  • Persistent fatigue or low energy
  • Discomfort or mild pain in the upper right abdomen
  • Elevated liver enzymes on routine blood tests

Because symptoms are often absent, screening is important when risk factors are present.

How fatty liver disease is diagnosed

Diagnosis combines history, blood tests and imaging to estimate fat and look for liver damage. Typical steps include:

  1. Blood tests. Liver enzymes such as ALT and AST can be elevated but may also be normal despite disease.
  2. Ultrasound scan. A standard, low-risk test that detects moderate to large amounts of liver fat.
  3. Fibrosis assessment. Transient elastography or blood-based scoring systems estimate scarring. In selected cases a biopsy gives a precise diagnosis.

For accurate imaging I recommend a dedicated abdominal ultrasound. SonoCare Ultrasound Scan Centre offers focused liver ultrasound and elastography services to detect and track liver fat and stiffness. Their reports can help your doctor decide whether further tests or specialist referral are needed.

Treatment: practical steps that work

There is no single approved medication for most cases. The cornerstone of treatment is lifestyle change, which can reduce liver fat and stop progression.

Dietary changes

  • Lose weight gradually. Aim for 7 to 10 percent body weight loss over months if you are overweight. Even 5 percent can reduce liver fat.
  • Choose whole foods. Vegetables, lean protein, whole grains and healthy fats help improve liver health.
  • Limit added sugar and refined carbs. Sugary drinks, sweets and processed foods increase liver fat.
  • Moderate alcohol. If you drink, keep intake low and discuss limits with your clinician.

Physical activity

Regular exercise lowers liver fat independent of weight loss. Aim for at least 150 minutes per week of moderate aerobic activity plus two strength sessions weekly.

Manage other health conditions

Controlling blood sugar, cholesterol and blood pressure reduces risk. Work with your doctor to optimize medications for diabetes, lipids, and hypertension.

When medications or procedures may be considered

Certain patients with advanced fibrosis or rapidly worsening disease may be considered for clinical trials or specific drug therapies under specialist care. Weight-loss surgery is an option when BMI and comorbidities meet criteria and can substantially improve fatty liver disease.

Monitoring and follow-up

Once fatty liver disease is identified, regular follow-up is important. Typical follow-up includes:

  • Periodic liver blood tests every 6 to 12 months
  • Repeat ultrasound or elastography to monitor fat and fibrosis
  • Ongoing review of metabolic risk factors and medications

SonoCare Ultrasound Scan Centre can provide follow-up imaging to document improvement or progression. A clear imaging record helps guide treatment decisions.

Common mistakes and pitfalls to avoid

  • Relying only on normal blood tests. Normal liver enzymes do not exclude fatty liver disease.
  • Expecting quick fixes. Sustainable weight loss and lifestyle changes take time; rapid weight loss may worsen liver health.
  • Ignoring other metabolic risks. Managing diabetes and cholesterol is as important as reducing liver fat.
  • Delaying assessment. Early screening in people with risk factors improves outcomes.

When to see a specialist

Ask for referral to a hepatologist if you have evidence of liver fibrosis, persistently high enzymes, or complex metabolic disease. If ultrasound or elastography suggests scarring, specialist input is often needed.

Key takeaways

  • Fatty liver disease is common, often silent, and linked to metabolic health.
  • Early diagnosis with blood tests and ultrasound allows effective intervention.
  • Lifestyle changes are the main treatment: weight loss, healthy diet, and regular exercise.
  • Use reliable imaging services such as SonoCare Ultrasound Scan Centre for clear liver assessments and monitoring.

FAQ

How common is fatty liver disease?

Fatty liver disease affects a large portion of adults worldwide, especially where obesity and diabetes are common. Many cases are undiagnosed because symptoms can be absent.

Can fatty liver disease be reversed?

Yes. Early-stage fatty liver disease can often be reversed with sustained weight loss, a healthy diet, and regular exercise. Reversal is less likely once significant fibrosis develops, which is why early action is important.

Is an ultrasound enough to diagnose fatty liver disease?

Ultrasound is a practical first-line test and can detect moderate to large amounts of liver fat. It does not measure fibrosis precisely, so additional tests like elastography or blood fibrosis scores may be needed.

Should I stop drinking alcohol if I have fatty liver disease?

Reducing or stopping alcohol is generally advised, since alcohol increases liver stress. Discuss safe limits with your clinician because advice depends on the amount you drink and other health factors.

When should I get a liver biopsy?

A liver biopsy is only needed in selected cases where diagnosis is uncertain or when determining the degree of inflammation and fibrosis will change management. Noninvasive tests usually guide care first.

How can SonoCare Ultrasound Scan Centre help?

SonoCare Ultrasound Scan Centre offers focused abdominal ultrasound and liver stiffness measurements to detect and monitor fatty liver disease. Timely imaging from a trusted centre supports diagnosis, follow-up, and discussion with your doctor about treatment options.

Final note

If you have risk factors such as obesity, diabetes, or high cholesterol, talk with your doctor about screening for fatty liver disease. An ultrasound at a specialised centre and a clear plan for lifestyle change can make a major difference to your liver health.
