YOGYAKARTA - The cause of fatty liver in people who do not drink alcohol is a health problem that is increasingly encountered in modern society. This condition, known as Non-Alcoholic Fatty Liver Disease (NAFLD) or Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD), occurs due to the accumulation of excess fat in liver cells without any relationship with alcohol consumption.

If not treated, this condition can develop into inflammation, fibrosis, cirrhosis, and liver cancer. The following is a complete explanation of the causes of fatty liver in people who do not drink alcohol and how to overcome it.

Understanding the Condition of Non-Alcoholic Fatty Liver

A healthy liver functions to process nutrients, store energy, and filter harmful substances. However, in non-alcoholic fatty liver disease, more than 5% of liver cells are filled with fat. This condition often does not cause symptoms in the early stages, so many cases are detected accidentally through ultrasound examinations or blood tests. The prevalence of NAFLD continues to increase along with sedentary lifestyles and high-calorie diets.

The Main Causes of Fatty Liver in People Who Do Not Drink Alcohol

Experts do not know the exact single cause, but the cause of fatty liver in people who do not drink alcohol is closely related to metabolic disorders in the body. Here are the main causes:

Obesity and Abdominal Fat Excess Obesity, especially visceral fat around the abdomen, is the most dominant cause. Excess body fat releases free fatty acids into the bloodstream which are then stored in the liver. The higher the Body Mass Index (BMI), the higher the risk. Insulin Resistance and Type 2 Diabetes Insulin resistance makes it difficult for the body's cells to use glucose, so the liver produces and stores more fat. People with prediabetes or type 2 diabetes have a much higher risk. Metabolic Syndrome The combination of obesity, hypertension, high blood sugar levels, and high cholesterol and triglycerides form the metabolic syndrome which is the main driver of liver fat accumulation. Unhealthy Eating Patterns Excessive consumption of added sugar (especially fructose from sugary drinks), processed carbohydrates, and saturated fats causes excess calories to be converted into fat in the liver. A diet high in junk food and low in fiber exacerbates this condition.

Lack of Physical Activity Sedentary lifestyle (less movement) decreases the body's ability to burn fat and worsens insulin resistance.

Additional Risk Factors

In addition, the causes of fatty liver in people who do not drink alcohol are also influenced by:

Genetic factors (e.g., PNPLA3 gene variants). Conditions such as hypothyroidism, PCOS, and sleep apnea. Use of certain medications (corticosteroids, tamoxifen). Too rapid weight loss.

Symptoms to Watch Out For

In the initial stage, it is usually asymptomatic. Subsequent symptoms include chronic fatigue, pain in the upper right abdomen, and liver enlargement. If it progresses to NASH (steatohepatitis), the risk of permanent liver damage increases dramatically.

Effective Prevention and Treatment

The good news is that this condition can be prevented and even reversed with lifestyle changes:

Lose weight gradually by at least 5-10%. Apply a healthy diet (lots of vegetables, fruits, lean protein, and fiber). Regular exercise at least 150 minutes per week. Control sugar, cholesterol, and blood pressure. Avoid sugary drinks and processed foods.

Consult a doctor for regular check-ups and proper treatment. There is no specific medicine that cures completely, so the main focus is on addressing the root cause.

The cause of fatty liver in people who do not drink alcohol is mostly from daily lifestyle choices. With early awareness and commitment to maintaining health, you can protect optimal liver function. Don't hesitate to check yourself if you have the above risk factors. Liver health is a long-term investment for better quality of life.
