What Are the Common NAFLD Symptoms?

Nonalcoholic fatty liver disease (NAFLD), also known as metabolic dysfunction-associated steatotic liver disease (MASLD), develops when excess fat accumulates in the liver. One of the main challenges with NAFLD is that it can remain unnoticed for a long time. Many people discover the condition only after routine blood tests or imaging performed for another medical concern.

Understanding the possible signs of NAFLD can help patients recognize when further evaluation may be appropriate. Because symptoms may be mild, vague, or completely absent during the early stages, medical assessment is often important for identifying liver changes and determining whether additional testing is needed.

Early NAFLD frequently causes few or no noticeable symptoms. When symptoms do occur, they may be subtle and can easily be confused with signs of other health concerns.

Possible early signs and symptoms may include:

• Persistent fatigue: Feeling unusually tired despite getting adequate rest.
• Low energy: Daily activities may feel more exhausting than usual.
• Upper-right abdominal discomfort: Some people experience mild pressure, fullness, or discomfort beneath the right side of the rib cage.
• General weakness: A person may notice reduced stamina or an overall feeling of low physical energy.
• Abnormal liver tests: Elevated liver enzymes may be discovered during routine laboratory testing.
• Fatty liver found on imaging: An ultrasound, CT scan, or other imaging study may show excess fat in the liver even before symptoms develop.

These symptoms are not specific to NAFLD and can occur with many different conditions. For this reason, our team encourages patients with persistent or unexplained symptoms to seek medical evaluation rather than trying to determine the cause on their own.

Yes. NAFLD can develop without causing any noticeable symptoms, especially during its early stages. This is why fatty liver disease is sometimes considered a silent condition. A person may feel healthy and continue normal daily activities even while excess fat is accumulating within the liver.

Important points to understand include:

• NAFLD may remain unnoticed for several years.
• A lack of symptoms does not necessarily mean the liver is healthy.
• Routine blood tests may provide the first indication of a liver concern.
• Fatty liver may be discovered incidentally during abdominal imaging.
• Symptoms do not always reflect the severity of liver fat or scarring.
• People with metabolic risk factors may benefit from appropriate liver evaluation.

Certain factors, including excess body weight, insulin resistance, type 2 diabetes, high cholesterol, and metabolic syndrome, may increase the likelihood of developing fatty liver disease.

Because NAFLD can remain silent, our team may review a patient’s medical history, laboratory results, metabolic health, and imaging findings when determining whether additional liver testing is appropriate.

NAFLD does not progress at the same rate in every patient. Some people may have fatty liver without significant inflammation or scarring, while others may develop more advanced liver changes over time.

As liver disease becomes more advanced, possible symptoms may include:

• Increasing or ongoing fatigue
• General weakness
• Persistent discomfort in the upper-right abdomen
• Reduced appetite
• Unexplained weight loss
• Yellowing of the skin or eyes
• Swelling in the legs or ankles
• Abdominal swelling caused by fluid accumulation
• Increased bruising or bleeding
• Difficulty concentrating
• Confusion or unusual sleepiness in severe cases

More serious symptoms are generally associated with advanced liver disease rather than uncomplicated early NAFLD. Progressive inflammation and fibrosis can eventually lead to cirrhosis in some individuals.

Advanced liver disease may interfere with the liver’s ability to perform essential functions, making regular monitoring particularly important for patients who have already been diagnosed with fatty liver or liver fibrosis.

Patients should consider medical evaluation when symptoms are persistent, unexplained, or occur alongside known risk factors for fatty liver disease. Because NAFLD may cause no obvious symptoms, patients should not necessarily wait for discomfort before discussing abnormal liver findings with a healthcare professional.

Reasons to schedule an evaluation may include:

• Persistent or unexplained fatigue
• Ongoing discomfort beneath the right side of the ribs
• Abnormal liver enzyme results
• Fatty liver discovered during imaging
• Diabetes or metabolic health concerns
• High cholesterol or triglyceride levels
• Obesity or significant excess body weight
• A previous diagnosis of fatty liver requiring follow-up
• New symptoms in someone with known liver disease

Evaluation may include a detailed medical history, physical examination, blood testing, and imaging studies. In some cases, additional noninvasive tests may be used to evaluate liver stiffness, fat accumulation, or possible fibrosis.

Certain symptoms deserve prompt medical attention, including:

• Yellowing of the skin or eyes
• Significant abdominal swelling
• Vomiting blood
• Black or bloody stools
• Severe confusion
• Sudden worsening of existing liver-related symptoms

These symptoms may indicate advanced liver dysfunction or another serious medical condition and should not be ignored.

At Digestive Disease Care, our board-certified gastroenterologists provide comprehensive evaluation for patients experiencing possible NAFLD symptoms or other concerns related to liver health. Our team understands that fatty liver disease can develop silently, which is why careful assessment is important when blood tests, imaging findings, or metabolic risk factors suggest possible liver changes.

Our team may assess several aspects of a patient’s health, including:

• Current symptoms and their duration
• Previous liver function test results
• Abnormal liver enzyme levels
• Personal and family medical history
• Metabolic health concerns
• Previous abdominal imaging results
• Possible liver fat accumulation
• Signs of fibrosis or liver stiffness
• Changes in liver health over time

Our clinic may recommend additional diagnostic testing when appropriate to better understand the condition of the liver. Noninvasive testing can help evaluate liver fat and stiffness and may provide useful information about the possibility of fibrosis without requiring an invasive procedure in many cases.
