A Guide to Nonalcoholic Fatty Liver Disease and Clinical Trials


It’s estimated that 25% of adults in the United States have fatty liver disease, a common condition that occurs when extra fat is stored in the liver. Although most of these people exhibit no noticeable symptoms, the disease can lead to serious liver damage and health concerns in the future. 

A healthy liver should contain a small amount of fat, usually under 5%. When that number grows, fatty liver disease (also known as steatosis) can occur. 

This can then eventually affect the body’s ability to:

  • Produce bile
  • Create proteins
  • Store iron
  • Convert nutrients into energy
  • Make immune factors and remove bacteria/toxins

What Are the Forms of Fatty Liver Disease?

Fatty liver disease is becoming increasingly common around the world, especially in Western nations. In the United States, it is now considered to be one of the most common forms of chronic liver disease. 

Fatty liver disease cases fall into two categories: 

1) Alcoholic Liver Disease

Fat can accumulate in the liver as a result of heavy drinking. It’s estimated that about 5% of Americans have alcoholic liver disease, and if drinking continues, serious damage or liver failure can occur. This is especially common in female heavy drinkers, have obesity, or possess certain genetic mutations. 

2) Nonalcoholic Fatty Liver Disease

Nonalcoholic fatty liver disease (NAFLD) occurs in people who do not drink heavily, sometimes early in life. Although certain factors do increase individuals’ risk, researchers have not identified an exact cause behind NAFLD. 

Because NAFLD is often symptom-free, especially in its early stages, many people are unaware of their condition for years at a time. As the disease progresses, some patients then develop nonalcoholic steatohepatitis (NASH), a more aggressive form of fatty liver disease. 

This can result in: 

  • Increased liver damage
  • Inflammation 
  • Scarring that can progress to cirrhosis
  • And in serious cases, liver failure 

The Symptoms of NAFLD & NASH

Because NAFLD does not usually trigger noticeable symptoms, it can be difficult to identify and diagnose. In the rare event that it does produce some signs upfront, individuals may notice:

  • Red palms
  • Yellowing of the skin and eyes (jaundice)
  • Feelings of fatigue
  • Discomfort in the upper right abdomen
  • Abdominal swelling (ascites)
  • Enlarged blood vessels beneath the skin’s surface

If NFALD progresses and the patient develops NASH or advanced scarring, the symptoms may worsen. Many NASH patients report the symptoms listed above, as well as:   

  • Nausea or weight loss 
  • Swollen legs 
  • Extreme tiredness
  • Mental confusion 
  • Physical weakness 

What Causes Fatty Liver Disease?

Scientists have yet to identify the exact cause of NAFLD. However, researchers have identified some environmental and genetic risk factors that can contribute to fat accumulation in the liver. 

Both NAFLD and NASH are highly linked to: 

Although obesity does not always equate to health problems like fatty liver disease, a poor diet, a lack of exercise, and other detrimental habits can increase the risk of NAFLD. Research has indicated that losing weight can help liver enzymes normalize and improve inflammation concerns.

Recent studies indicate there is a complex link between NAFLD and type two diabetes mellitus. It’s estimated that at least half of those with type 2 diabetes face fatty liver disease, as well as increased risks of liver cancer and other serious diseases.

The liver is a key determinant of metabolic abnormalities, including heart disease, stroke, and type 2 diabetes. All of these conditions fall under the umbrella label of “metabolic syndrome” and can cause people to hold excess body fat around the waist, increasing the risk of NAFLD and NASH.

Several drugs have been implicated in the causation of fatty liver disease, including: 

  • Corticosteroids
  • Tamoxifen
  • Antipsychotic medications
  • Antidepressants 

More research is required to understand if NAFLD is a direct result of the medication on the liver or a consequence of the weight gain the medications trigger. Either way, it is believed that some medications could significantly increase the risk of fatty liver disease.

How is Fatty Liver Disease Diagnosed?

Because there are few noticeable symptoms associated with the early stages of NAFLD, it’s a difficult disease to diagnose. However, if the disease causes the patient to develop nonalcoholic steatohepatitis eventually, the symptoms may be easier for medical professionals to use in diagnosis. 

Doctors can also order blood tests to assess liver enzymes for a diagnosis. Some experts may also call for ultrasounds, CT scans, liver biopsies, or other specialized scans.

Treating Fatty Liver Disease

There is no medication specifically created to battle fatty liver disease. When most patients are diagnosed with NAFLD or NASH, doctors primarily focus on controlling the factors that contribute to the disease. 

This often involves making nutritional and lifestyle changes such as:

Patients with fatty liver disease should likely not drink alcohol, even in moderate amounts. This is especially true for patients that have already experienced liver scarring or damage.

Fatty liver disease is significantly impacted by weight loss and physical activity. Most doctors place patients on diet and exercise plans to improve the liver’s functioning and promote long-term health. 

In serious NASH scarring situations, treatment is more challenging. Still, cutting down on excess body weight is one of the most recommended ways to stall the condition’s progression.

Some medical professionals may advise patients with fatty liver disease to take supplements such as vitamin E, probiotics, or fish oil to promote a healthier lifestyle. Because diet does play a role in the risk of fatty liver disease, using the right supplements can prevent the condition from worsening. 

In many cases, fatty liver disease is an early warning sign that occurs prior to liver failure, cancer, or cirrhosis. The sooner patients can seek treatment and correct the problem, the better.

NASH Clinical Trials

If you have been diagnosed with fatty liver disease, you have the opportunity to participate in clinical studies and help researchers obtain valuable information – both for your benefit and for the future care of others. 

Researchers are currently studying many aspects of nonalcoholic fatty liver disease (NAFLD), nonalcoholic fatty liver (NAFL), and nonalcoholic steatohepatitis (NASH). This includes the assessment of: 

  • New treatments for NASH
  • How genes and environmental factors increase the risk of NAFLD
  • How liver diseases develop and progress 

These clinical trials are carried out in reputable hospitals, universities, and research centers. If you’re interested in participating, reach out to learn about clinical trials in your area. 

Helping Friends or Family With Fatty Liver Disease

Has your loved one been diagnosed with fatty liver disease? Whether they have NAFLD or NASH, there are things you can do to assist them on their healing journey.

Offer Emotional Support

Because treatment often involves serious life changes, emotional support is crucial to fatty liver disease patients. Listen to their complaints and encourage them when things get tough.

If appropriate, offer to attend doctor’s appointments with them. It always helps to have someone in your corner when facing a health challenge. 

Exercise together

Exercise Together

A combination of healthy eating and increased activity is often the first line of defense against fatty liver disease. Therefore, one of the best ways to support individuals with NAFLD or NASH is to accompany them on their exercise journey. Offer to sign up for a workout class together or keep them company on their daily walks.
