As modern lives improve, we get to have a huge feast whenever we want; to catch up with our workload amidst endless distractions, we often have to stay up until late night to finish them. Such a lifestyle is no stranger to most people in today’s age, but do you know that it can take a great toll on your liver, the organ that detoxes your body and ensures everything else runs smoothly?

Nonalcoholic fatty liver disease (NAFLD) is increasing rapidly in the Asia-Pacific region, including Malaysia. It is a very common disorder and refers to a group of conditions where there is accumulation of excess fat in the liver of people who drink little or no alcohol. For people who experience liver damage as a result of habitual drinking, another term is used, called alcoholic fatty liver disease.
NAFLD develops in 4 main stages, each with different signs and symptoms, treatment requirement and prognosis (i.e. A forecast of the likely outcome):
The most common form of NAFLD is a non-serious condition called fatty liver. In fatty liver, fat accumulates in the liver cells. As weight gain and obesity become more common, more and more people develop fatty liver. Although having fat in the liver is not normal, by itself it probably does not damage the liver. Most people with fatty liver do not have any symptoms and their liver functions are still considered normal.
However, as fatty liver worsens, some people may go on to develop a more serious form of NAFLD known as non-alcoholic steatohepatitis (NASH). In NASH, fat accumulation can result in liver cell inflammation. The exact causes of NASH is not known yet, but it is more commonly seen in people with metabolic syndromes. More on that later.
Following NASH, the persistent inflammation of liver cells results in different degrees of scarring in the liver tissues and blood vessels. The liver is still able to function properly, but things are not looking good if the condition continues to deteriorate.
Cirrhosis occurs when the liver experiences substantial damage after several years, and the liver cells are gradually replaced by scar tissue, which results in the inability of the liver to work properly. Ultimately, liver failure happens and this damage is permanent. Some patients who develop cirrhosis may eventually require a liver transplant. In some cases, people with severe forms of NASH even go on to develop liver cancer.
The prevailing theory is that fatty liver gets started because of insulin resistance, which is, in turn, frequently a consequence of obesity and excess fat tissue in the abdomen. When people are insulin resistant, their muscle, fat, and liver cells don't respond normally to insulin, so levels of the hormone — and the blood sugar it ushers into cells — build up in the blood. As a result, the risk of developing diabetes and heart disease increases.
But insulin resistance is a complicated metabolic state that also causes another phenomenon: it increases the amount of free fat molecules called fatty acids circulating in the blood. Those fat molecules often ended up in— you guess it— your liver. Your liver cells start to get inflamed when they are wrapped around in fats, and you know the rest of the story. So really, the key to improve your insulin resistance and liver health is to control your body weight.
Most of the time, patients with NAFLD do not have any symptoms. This is why NAFLD is a tricky condition– it is a silent killer that gives no warning signs. Some patients with nonalcoholic NASH (stage 2) may complain of fatigue, general unease, and a vague discomfort in the upper abdomen area. You are likely to discover that you have NAFLD because blood tests revealed an abnormal liver function test or when you have imaging tests of the abdomen for other reasons (such as an ultrasound being done to look for gallstones).
You're at an increased risk of NAFLD if you have:
are obese or overweight – particularly if you have a lot of fat around your waist (a “muffin top” body shape). The International Diabetes Federation 2009 defined obesity as waist ≥94 cm in men or ≥80 cm in women.
have type 2 diabetes
have high blood pressure
have high cholesterol
have metabolic syndrome (a combination of diabetes, high blood pressure and obesity)
are over the age of 50
smoke
But NAFLD has been diagnosed in people without any of these risk factors, including young children.
Unfortunately, there is no cure for non-alcoholic fatty liver disease (NAFLD). However, treatment plans are available to salvage loss.The treatment of NAFLD aims to treat the underlying causes, such as obesity, high blood pressure, high cholesterol, diabetes etc.
As we have emphasized over and over again, overweight and obesity increase the risks of developing fatty liver. The best thing you can do to help your liver is control your body weight, which improves your insulin sensitivity and ward off fatty liver. But we encourage you to take it steadily, as rapid weight loss can actually worsen your liver disease!
You may aim for a loss of 0.5-1kg body weight per week by healthy eating and physical activity. Do work with a healthcare professional such as a nutritionist to come up with a weight loss plan that is safe, healthy and sustainable for you. In morbidly obese cases, you may consult specialist on weight loss medications or bariatric surgery. Do not try any weight loss treatment without consulting a healthcare professional.
If you have any conditions that we mentioned above, such as diabetes, high blood pressure and high blood cholesterol, ensure they are well-controlled by strictly following the treatment plan prescribed by your doctor. Occasionally, doctors may prescribe insulin sensitizers, such as pioglitazone and liraglutide, to people with NAFLD and diabetes. These are medications that improve the action of insulin produced by the body, which in turns improves NAFLD. Vitamin E has also been shown to provide improvements for people with NAFLD, probably due to its antioxidant properties.
A healthy lifestyle includes eating a balanced diet high in fruits, vegetables, protein and carbohydrates, but low in fat, sugar and salt; exercise regularly (aim to do at least 150 minutes of moderate-intensity activity, such as walking or cycling, a week); and stop smoking if you do.
The United States of Centers for Disease Control and Prevention (CDC) recommends that individuals with with chronic liver disease (including, but not limited to, persons with cirrhosis, fatty liver disease, alcoholic liver disease, autoimmune hepatitis, or abnormal liver function test) to receive vaccination against Hepatitis A and B. Check with your doctor to see if you need them.
