Fatty Liver: Symptoms and Causes

The liver is the largest gland of the body. It performs many crucial functions like digestion, detoxification, protein synthesis and is the only organ that can regenerate. Fatty liver disease is a common condition resulting from the accumulation of extra fat in the liver. Let’s know what causes fatty liver and its symptoms in this blog.

What Causes Fatty Liver?

Many people link fatty liver to heavy alcohol drinking. But nowadays it is becoming common in people who don’t drink any alcohol at all. This is because of changing dietary and lifestyle habits.

Unhealthy Diet

Hectic lifestyle and easy availability of ready to eat food make more people eat more junk foods and high-calorie foods like sweets, meats. Consumption of carbonated drinks, packed juices, and energy drinks is also on the rise.

These may lead to more fat absorption and increases the workload on the liver. Eventually liver fails to process and break down this extra fat. This excess fat builds up in the liver cells developing the fatty liver.


Just like overeating, malnutrition is also one of the causes of fatty liver. Protein-calorie malnutrition affects liver cells, causes liver enzyme imbalances and mitochondrial changes that can lead to NAFLD.

Poor Lifestyle

A sedentary lifestyle, physical inactivity, chronic alcohol drinking, and smoking are associated with high rates of fatty liver. Many studies suggest that individuals who do not engage in moderate or vigorous physical activities have increased incidence and severity of the non-alcoholic fatty liver disease.
