Fatty Liver Disease in Depth: Typical Signs and Symptoms, Alcoholic and Non-Alcoholic Causes and Dietary & Medicine Treatments


Fatty liver disease may not receive the widespread attention of larger scale health problems like heart disease and cancer, but liver problems can be highly dangerous and very difficult to pick up on in their early stages if you don’t know what to look for.

While much liver disease is related to alcohol and drug abuse, in many cases there is a strong genetic factor combined with high cholesterol levels and obesity – in other words, it’s often a combination of genetics and diet.

This page will delve into how to pick up on the early warning signs of fatty liver disease, treatments and diets for the disease, how alcohol and liver disease go hand in hand and how the liver can regenerate itself.

Just read on and learn more.

What Is Fatty Liver Disease? – Well, It Starts with too Much Fat

CT scan of a liver with fatty liver disease.As you have probably guessed from the name, fatty liver disease is a condition in which the fat content of your liver grows to an unsafe level.

It is normal for your liver to contain a small amount of fat – just as all your vital organs require fat to function normally (this is why even bodybuilders never get down to 0% body fat – you need that fat to stay alive!).

The problems start occurring when the percentage of your liver made up of fat moves beyond a particular threshold – the safe level can differ based on genetics, but generally if your liver’s fat content goes higher than 10% you are likely to experience some significant problems.

Bear in mind that a high fat content in the liver doesn’t constitute a disease in itself. The disease develops when this excess fat content starts triggering problems such as liver inflammation.

Let’s now look at the symptoms of fatty liver disease so you know what to watch out for.

Typical Symptoms and Signs of Liver Problems

As mentioned, a fatty liver in and of itself is often not particularly problematic – as a result, many people don’t even know they have fatty liver.

It’s the more serious conditions which fatty liver can lead to which are the biggest cause for concern.

This can make catching fatty liver in its early stage troublesome, because the disease itself doesn’t display significant symptoms in most cases.

Liver problems are only noticeable once the damage has reached a more advanced stage.

Watch out for Steatohapatitis – When the Liver Fat Triggers Inflammation

Liver problems such as steatohepatitis may lead to fatigue and problems concentrating.The most common concern is steatohepatitis – when the liver’s fat content triggers inflammation, at which point the signs that something is wrong begin to manifest themselves, often in the form of:

  • Fatigue
  • Difficulty concentrating
  • Confusion
  • Jaundice (yellowing of the skin and whites of the eyes)
  • Swelling and bruising are also common symptoms.

Another major concern is liver cirrhosis, which we will discuss towards the end of this article – but for now let’s look at the differences between fatty liver disease caused by alcohol and the non-alcoholic version of the illness.

The Two Different Versions of Fatty Liver Disease – The Alcoholic and Non-Alcoholic

Alcohol and Liver Disease

Medicine draws a distinction between alcoholic and non-alcoholic fatty liver disease.

While heavy drinkers often tend to be in denial about the extent of their problems and may even tend to ignore physical symptoms rather than face them head on, the medical statistics are fairly shocking when it comes to alcohol consumption and fatty liver disease.

Heavy Drinking almost Always Leads to Fatty Liver Disease in the Long Run

Picture of liver with too much fat from drinking too much alcohol.Almost all heavy drinkers develop fatty liver disease over the long run if they don’t reign in their drinking, and a high percentage (about 20%) of chronic drinkers will also develop more severe liver-related conditions like cirrhosis.

However, research has shown that in drinkers who consume over 60 grams of alcohol on a daily basis, over the long run the development of fatty liver is virtually guaranteed.

Although the incidence of liver disease in alcoholics is extremely high, it is still non-alcoholic fatty liver disease which is more common in the United States and other developed countries today, largely as a result of high-cholesterol, high-saturated-fat diets.

The Good News about an Alcoholic Fatty Liver

Although alcoholic and non-alcoholic fatty liver disease share similar names, they are actually quite different in terms of the bodily processes involved.

Alcohol itself actually directly causes an inflammatory reaction. On the positive side, alcoholic fatty liver is a condition that can be reversed if it’s caught early enough.

Other Fatty Liver Disease Causes:
– Medications, High Cholesterol and High Fat Diet, Malnutrition, Type II Diabetes and Obesity

So far we’ve focused on diet and alcohol as causes of fatty liver disease, and while these two factors (combined with genetics) are the biggest causes of the disease, there are others which should also be taken into consideration.

1) Fat Inducing Medications

Side effects from some types of medications may lead to storing of fat in the liver. Some medications, for example, have unfortunate side effects.

These side effects can affect the liver’s metabolism functions and consequently lead to a build-up of fat in the liver.

Drugs other than alcohol can also damage liver function and cause a build-up of fat in the organ.

2) Unfortunate Genetics

Sometimes, liver disease is simply hereditary – it comes from a person’s genetics and their lifestyle choices have little to do with it.

3) Poor Diets: Eating too much of the Wrong Stuff OR too Little of the Good Stuff

There is also another way in which diet can lead to fatty liver disease.

Not only does a high-cholesterol, high-fat diet put you at greater risk, but there are also risks at the opposite end of the spectrum: not eating enough. Eating disorders, malnutrition and attempts at rapid weight loss can contribute to the development of liver problems.

4) Type II diabetes and obesity

Obesity and fatty liver disease. Picture of Venus from Villendorf.Also, as a final note it’s worth remembering that it is not necessarily diet itself which causes fatty liver disease.

Often it is other diet-related problems such as Type II diabetes and overweight, obesity.

In other words, two people can eat similar diets, but if one is overweight or even obese and the other is at a healthy weight, the obese person is likely to be at higher risk of developing liver disease.

And again, this is the case even if their fat and cholesterol intakes are similar. Unfair, but true

Fatty Liver Disease Treatments: Cut the Alcohol (if You Drink), Change Your Diet and Possibly Get Some Medication

No drinking if you have a fatty liver. Picture of a glass of wine.The treatment which your doctor will recommend will first of all be based on whether you’re suffering from alcoholic or non-alcoholic fatty liver disease.

In the case of alcoholic liver disease, the first step is usually a complete cutting of alcohol from your diet. This is often a battle for people who have a strong addiction to drinking, even though they know continued indulgence in drink can cause them severe long term harm.

Treatments typically revolve around dietary changes, medication, and increases in antioxidant intake, or some combination thereof.

While most doctors focus primarily on diet and medication, there is evidence that supplements such as milk thistle may help the liver regenerate (although the liver regenerates itself naturally under the right conditions).

Healthy Fatty Liver Diet Tips

Now that you’re aware of the major causes of fatty liver disease in most cases, you can probably take some accurate guesses at the best foods to include (and exclude) when putting together a fatty liver diet.

Obviously, cutting alcohol altogether is a great idea – even if you’re not suffering from alcoholic fatty liver. Controlling cholesterol is also a big plus, by ensuring a healthy level of ‘good’ cholesterol while restricting your ‘bad’ cholesterol intake as much as possible.

Obviously, however, risk factors such as diabetes can’t be kept in check by diet alone.

Fatty liver disease is complex, and depending on how advanced your liver problems are you may be at a point where medication is necessary.

No Standard Medicine: Liver Medicine Depends on the Cause of the Fatty Liver

The medication prescribed for you by your doctor will vary depending on exactly what your biggest risk factors are.

For example, if high cholesterol is an issue you may be prescribed medication for lowering triglyceride levels.

Because of the complex nature of fatty liver and the wide variety of causes, there is no standard ‘go-to medicine’ for doctors. Your treatment will be based on your individual requirements after a thorough assessment of the causes of the problem in your own situation.

Liver Repair and Regeneration

The Liver Repairs Itself BUT … only Under the Right Conditions

As mentioned previously, the liver actually regenerates itself under the right conditions which is great news.

However, this knowledge has been used by many alcoholics to justified continued excess drinking, so we need to clarify what those ‘right conditions’ are.

It all Goes Wrong When You Overwhelm Your Liver – Cut Your Liver Some Slack so It Can Rebuild

Fat build-up in the liver occurs, generally speaking, because the metabolic functions the liver normally serve become overwhelmed – in simple terms, the ‘input’ coming into the liver (in the form of alcohol, for example) is greater than the liver’s maximum processing capacity.

In order to repair itself, this ‘input’ needs to be dropped to a level the liver can manage – the liver will then be able to continue with its normal metabolic functions until the system has been ‘cleaned out.’

Liver Cirrhosis – When Scar Tissue Occurs and Your Liver Cannot Repair Itself

The process of fatty liver disesase to cirrhosis.Now, it’s very important to follow up these notes on liver repair and regeneration by touching on liver cirrhosis.

Many heavy drinkers and poor dieters rely on a vague understanding that their liver can ‘heal itself.’

While this is true to a certain extent, there is a limit – when damaged liver cells can’t repair and become replaced by scar tissue.

This tissue is unable to regenerate itself, and as a result leads to permanently impaired liver function.

The process of healthy liver cells being replaced with scar tissue is called liver cirrhosis.
