Hepatic Steatosis, better known as Fatty liver is a term which describes the condition where fat gets built up in the liver. The liver is the second largest organ in the body and it plays an important function of processing everything we eat or drink and then filter out harmful elements from the blood. This process gets interrupted if there is too much in the liver. We generally call the liver as fatty, when fat accounts for more than 5 to 10 percent of the weight of your liver.

The problem of fatty liver is quite common, affecting around 10 to 20 percent of people living in America without cirrhosis or inflammation. According to the American Liver Foundation, the majority of the cases of fatty liver are detected between ages 40 and 60.

Symptoms of fatty liver
Basically one cannot associate any symptom with fatty liver, though once this situation arises, people might experience fatigue or unusual discomfort in the abdomen.
Excess fat in the liver can lead to its inflammation and in that case, you might come across symptoms such as:

You don t feel like having any food due to poor appetite
One starts to lose weight
You might experience pain in the abdomen, which tends to interfere in your passing of urine.
As there is a loss of appetite, resulting in weight loss, muscles would start feeling weak.
Due to weakness in your muscles, you would easily get tired even when you have not any work that required a lot of exertion.
Causes of fatty liver
The most common reason behind fatty liver is alcohol. On the other hand, fatty liver can also occur among people, who are non-alcoholic.
In those circumstances, the fatty liver gets developed when the body creates too much fat or is unable to metabolize fat fast enough. The excess fat gets stored in the cells of the liver where it gets accumulated to form fatty liver disease.

The common causes for fatty liver, other than alcoholism are:

Obesity: Obesity is a condition when you gained too much bodyweight through accumulation of excess body fat. This becomes a major problem which leads to other problems like fatty liver.
Diabetes: Excess amount of blood sugar in your system, which results in diabetes, raises the risk of developing fatty liver disease.
Genetic Inheritance: If you have someone in your family, father, mother or anyone else, who has suffered from this problem of fatty liver, then it s quite certain that you might also catch up with this disease.
Treatment for fatty liver
You are always at risk if you get diagnosed with the problem of the fatty liver through blood tests, MRI scan and liver biopsy. Though there is no medication or surgery possible for treating this problem a doctor would provide certain recommendations to reduce the risk factors. These include:

Limiting or complete avoidance of alcohol
Keep a check on cholesterol and reduce the intake of sugar and other saturated fatty acids
Make a genuine attempt to lose weight
Control your blood sugar by walking daily and having a restricted diet

Fatty Liver Disease - Ways It Can Be Treated!

The liver is the second largest organ in the human body. Everything that is consumed goes through the liver and gets metabolized. Generally the liver consists of fat accumulation, in the range of 2%, but when it reaches close to 10%, the condition is termed as fatty liver. Progression of fatty liver can lead to cirrhosis and eventually liver failure. The liver has an amazing ability to regenerate itself if a part of it is damaged. 

However, if the damage is cumulative, then the repair becomes difficult. Another point to note is that the liver can be resected in parts to ensure that the non-affected liver continues to be available to take care of the metabolism.

Causes: There are two main types of fatty liver:

Alcoholic fatty liver: This is the most common type and is seen in heavy drinkers.
Non-alcoholic steatohepatitis (NASH): The causes for this type are not clear, but obesity, diabetes, and hyperlipidemia are some causes for NASH.
Symptoms: Fatty liver develops over years, and the symptoms are both vague and appear randomly. These can be attributed to any general illness, and so diagnosis is often delayed.

Unexplained weight loss
Jaundice
Loss of appetite
General malaise
Dull pain in the right upper quadrant of the abdomen
Overall physical weakness
Ascites or fluid accumulation in the abdomen
Increased tendency to bleed
Abnormal liver enzyme levels
Diagnosis: If suspected of fatty liver, the following are done to confirm the diagnosis.

Blood tests to check for liver enzyme levels.
Imaging studies including x-ray, CT and/or MRI scan
Biopsy to confirm the diagnosis
Treatment: Fatty liver is a completely reversible condition. If a person with alcoholic fatty liver quits drinking for about 8 to 10 weeks, the damage can be totally reversed.

If there is no history of alcoholism but obesity, then switching to a non-fatty diet with lots of fresh fruits and vegetables, multigrain, dairy products, etc., can help in controlling fat accumulation and use the stored fat. Increasing the levels of physical activity also helps in burning stored fat.

As noted, the liver is capable of self-repair and self-regeneration, so if further triggers are stopped, it can heal itself.

If fatty liver is not controlled, it can develop into cirrhosis and liver failure. If it reaches liver failure, then survival rates and prognosis look very gloomy.

Prevention: Fatty liver disease can be prevented by controlling alcohol intake, adopting a healthy lifestyle, eating non-fatty and non-sugary products, and maintaining an active and healthy lifestyle.

Monitor health periodically to check on liver function, diabetes, and cholesterol levels.

Fatty Liver - All You Need To Know!

Fatty liver is a condition where excess fat is deposited on this organ. Also called as steatosis, this condition happens when more than 5- 10 percent of the weight of the liver is made up of fat.

Fatty liver is a common condition among people. A study from coastal regions of India found ~ 25% of healthy persons had patients had fatty liver on ultrasound.

It can occur at all ages including childhood, highest prevalence is in 40 50 year age group. Prevalence more in patient who are obese and in diabetic patients.

Types of Fatty Liver

1 Alcoholic fatty liver: This condition occurs when there is a heavy consumption of alcohol. Gastroenterologists recommend abstention from alcohol for this condition to subside. If the patient continues to consume alcohol, then liver cirrhosis may develop.

2 Non alcoholic fatty liver (NAFL): One may develop a fatty liver even if one is not an alcoholic. The liver in some cases is unable to process the fat in cells causing them to build-up on the organ.

When more than 10% of the liver is made of fat then this condition is called Non Alcoholic Fatty Liver (NAFL).

Non alcoholic steatohepatitis (NASH): When fatty liver is associated with inflammation in liver patient is said to be having Non alcoholic steatohepatitis. NASH is a more advanced stage of NAFLD, and has a higher risk of progressing to liver cirrhosis or hepatocellular carcinoma (HCC). These condition display symptoms like jaundice, vomiting, nausea, loss of appetite and abdominal pain. Blood test (LFT) shows raised enzymes level. Approx 5-8% of the Indian population has NASH. Consult a doctor if you are experiencing any of these symptoms.

3 Fatty liver during pregnancy: Occurring mainly in the third trimester, the symptoms of this condition are vomiting, nausea, pain the right part of the abdomen and jaundice.

Symptoms

During the early stages (fatty liver) of the disease, patients usually have no symptoms directly related to liver disease. However, people may experience a vague abdominal discomfort. If their liver is inflamed (NASH) then they may display symptoms of poor appetite, weight loss, pain in the abdomen and disorientation.

What causes fatty liver?

The most common cause of fatty liver is alcoholism. When the human liver is unable to metabolize fat fast enough or when there is an excess accumulation of fat on the liver cells then the liver becomes fatty. However, intake of high-fat foods may not result in a fatty liver.

Predisposing factor:

1 Diabetes mellitus

2 Obesity or being overweight

3 Hyperlipidemia or the condition where there are high levels of fat in the blood

4 Genetic reasons

5 Rapid loss of weight

6 Drugs: Aspirin, steroids, tamoxifen, tetracycline etc. cause side effects which also leads to fatty liver

7 Nutritional status (eg, overnutrition, severe malnutrition, total parenteral nutrition [TPN], or starvation diet)

8 Other health problems (eg, Hepatitis C infection, celiac sprue and Wilson disease)

Know More About Fatty Liver!

The liver is the engine of the human body. It is basically composed of 2 types of cells (a cell is the basic building block of the human body)   hepatocytes (liver cells) and cholangiocytes (bile duct cells). It also has other supporting tissue and their respective cells. The hepatocytes are by far the most numerous cell type, not surprisingly tumours (otherwise called mass or lump.  Tumor  means lump in Latin), of this cell form the majority of abnormal growths in the liver. Abnormal growths can be benign (that is, they do not grow rapidly, spread to other parts of the organ or to other parts of the body) or malignant (grow rapidly, spread to other parts of the organ and to other parts of the body, i.e. cancer). These abnormal growths from liver cells are Focal nodular hyperplasia (FNH), Adenomas (the benign variety) and hepatocellular cancer (otherwise called Hepatoma/HCC, the cancerous type). What we need to recognize is that certain adenomas can turn into HCC, over a period of time. The other type of growths in the liver are those that have originated elsewhere in the body and spread to the liver, for example a growth of the breast spreading to the liver. These are in fact the commonest tumours of the liver. I will discuss these at a later date.

Benign growths of the liver

Common benign growths are Haemangiomas, FNH and Adenoma. Most of these are identified when a scan is performed as investigation for some other problem. Accurate diagnosis of the nature of these lumps is important to determine the type of treatment needed. This can be ascertained by a carefully selected scan like an Ultrasound, CT scan or an MRI. The technology of these scans is continuing to evolve and get better year on year. There are different types of Ultrasound, CT and MRI scans with different applications, based on whether contrast is used or not, the different phases of scanning, the type of MRI scanning sequence etc. Therefore, these scans although commonly available and used very frequently, need to be performed under the supervision of a team involving Liver doctors and radiologist who is well versed in the diagnosis of liver lumps, for accurate diagnosis without the need for unnecessary tests (Box 1).

Haemangiomas are by far the commonest. It is estimated that 5% of the adult population harbor this lump in their livers! They occur in both sexes and at all ages but are commonest between 30 to 50 years in women. Most of them are small, less than 4-5 cms in diameter and are are identified on Ultrasound. MRI and its various applications is the scan of choice for accurate diagnosis. This is crucial as most of them do not need treatment.

Focal Nodular Hyperplasia (FNH) are the second most common liver lumps. They are usually single and small (less than 4 cms) and occur in women between 35   50 years of age. About 2.5-3% of population harbor this lump in their livers. Special MRI techniques using special contrast agents is diagnostic and the findings are quite distinct from haemangiomas. Again treatment is not recommended apart from selected circumstances. Assessment in a dedicated Liver team is recommended for accurate diagnosis and a proper management plan to be formulated.

Hepatic adenomas (Hepatocellular adenoma, HCA) are rare lumps and occur in 0.2 to 0.3% of the population, again occurring mostly in young women during their reproductive period. They are again solitary and most usually 3-4 ms in diameter.

There are a couple characteristics which make this lump different from the previous 2, there is a strong relation between hormones the development of HCA and some of these HCA can turn into the malignant Hepatocellular carcinoma (HCC). Therefore, accurate characterization and diagnosis of these HCA is essential. Sometimes biopsy of the lump, molecular and genetic tests maybe necessary to determine if the HCA has a high chance of progressing to HCC. Imaging tests are generally adequate, contrast MRI Liver and its different techniques is accurate in diagnosing HCA and sub-typing it, however CT and contrast-enhanced Ultrasound is sometimes necessary along with MRI.

Generally, a HCA in a male is recommended for surgical resection. While in women, discontinuation of the OCP pill/ any other such hormone is recommended for a period of 6 months, if the HCA does not have any worrying features and size is less than 5 cms. IF HCA is larger than 5 cms and has features suggestive of a high risk for change to HCC, surgery is advised. Again these decisions have to be made as a part of a Multi-disciplinary team (Box 1)

Malignant growths beginning within the Liver

As mentioned earlier, usually malignant growths which are seen in the liver spread to it from elsewhere in the body. Hepatocellular cancer/Hepatoma (HCC) is the commonest malignant tumour beginning within the liver, as apposed to those that spread to the liver from elsewhere. It occurs between 40-70 years of age and occurs commonly in men. It is estimated that 17000 new patients develop this tumour every year in India. The vast majority (> 80%) of these develop in patients who have chronic liver disease (cirrhosis). Importantly the number of HCC cases is increasing year on year as cirrhosis due to fatty liver disease, Hepatitis B (3% of Indian population carry this virus, ie nearly 40 million individuals) and alcohol are continuing to increase in India. Nearly overall it is the 4th or 5th most common cause of cancer and the second most common cause of cancer-related death. This is continuing to increase too. We do not have a national policy in India to screen and diagnose these lumps in the liver at an early stage. Most patients present at a late stage when effective treatment is not possible.

Hepatitis B is a vaccine-preventable disease, there are good drugs to treat it and decrease the risk of cirrhosis and HCC in HBV patients, therefore it is important to test for this virus infection. The fatty liver disease can cause chronic liver damage and HCC, regular exercise and consuming a balanced diet can reduce the risk of fatty liver disease.

The usual mode of detection of these growths is when a scan is done for some other reason. Occasionally patients can develop pain in the abdomen or jaundice which leads to an investigation. The treatment of HCC depends on the extent of tumour, the extent of the chronic liver disease (the stage of cirrhosis) and the overall condition of the patient. These patients are best seen, assessed and treated in a team (Box 1) which specializes in the treatment of Liver disease.

The best treatment for HCC is surgery. However, this is suitable only for certain carefully selected patients. This can take the form of liver resection (where a portion of the liver with tumour is removed) or liver transplantation (where the whole liver is removed and a donated liver (full or partial) is replaced into the patient. Indeed surgical has excellent survival rates; more than 75% of patients survive for more than 5 years after resection or transplantation making treatment for these cancers one of the most satisfactory.

Other treatments which can be combined with surgery in selected patients or can be combined with patients not suitable for surgery are different types of Interventional radiological therapy   chemotherapy or radiotherapy delivered through fine catheters introduced into the blood vessels of the liver (TACE: Transarterial chemotherapy, TARE: Transarterial radiotherapy) and or heat energy delivered to the tumour area by means of carefully placed needles/probes (RFA: radiofrequency ablation, MWA: microwave ablation).

HCC is unique cancer as its treatment should be tailored to the patient, the treatments are varied and range from catheter-based non-invasive treatment to major surgery and transplantation. This necessitates that HCC patients are best managed in a multidisciplinary team which is highly skilled in and specializes in the management of liver diseases.

Box 1: A liver tumour multidisciplinary team   Integrated Liver Care team

The team should be one with expertise in the management of benign liver lesions and should include a Hepatologist, a Hepatobiliary & Transplant surgeon, Diagnostic and Interventional radiologists, Medical oncologist and a Pathologist.

Each member of the team must hold specific and relevant training, expertise and experience relevant to the management of benign liver lesions.

The team should be one with the skills required not only to appropriately manage these patients but also to manage the rare but known complications of diagnostic or therapeutic interventions.

The Increasing Problem Of Liver Tumours In India!

Sugar is the trigger to most of the diseases an adult faces in present times. Sugar is not only harmful for adults, but can pose severe threats to the health of a child as well, if not administered in monitored proportions. But again, sugar is indispensable when it comes to sweetening your drinks and desserts. In order to prevent yourself from the health hazards of sugar, you should know more about its scope and effects.
1. Sugar can lead to a fatty liver: Fatty liver is a troubling issue faced by many across the globe. It is wrong to think only alcoholics are subjected to this health condition. People who exercise little and consume huge amounts of fructose are also exposed to the threat of this disease. When a person doesn't do enough to burn up the existing amount of glycogen in his or her liver and take in fructose repeatedly, the liver turns that fructose into fat, impairing one's liver capabilities to a great extent.

2. Sugar may make you resistant to Leptin: Leptin is a hormone released by your fat cells. The hormone is particularly necessary as it sends signals to your brain telling it you are full and won't be requiring any more food. Fat people have more number of fat cells and thus additional Leptin too. The Leptin becomes inactive due to the effects of heightened blood triglycerides and insulin, both of which counter its functioning.

3. It is addictive and there lies the key to temptation: Sugar is enormously addictive. If you like sweetened products, you will find it hard to resist your cravings for cakes, cookies or chocolates. Sugar accelerates dopamine secretion; this hormone makes a person feel good. Dopamine is the hormone released on the consumption of drugs such as cocaine.

4. Calories in sugar are not balanced out with any mineral or vitamin: Because of its lack of nutrient value, sugar is said to have empty calories. Food items rich in sugar tend to make a person lethargic and slackened while depriving them of essential minerals and vitamins. It is therefore, best to not allow children to have pastries, chocolates or puddings in excess.

5. Sugar leads to extensive tooth decay: Sugar can accumulate on your teeth if you are having too many sweetened food items. This causes your teeth enamel to wear away, making it more prone to cavities and dental caries.

Why You Should Stay Away From Sugar?

Having some fat in your liver is legit. But, if you have too much of fat say more than 5%-10% of the organ's weight then you are at risk of getting fatty liver disease. At the onset, you can do one important thing to help your liver stop drinking. It causes fatty liver disease.

There are two main types of fatty liver disease

Alcoholic liver disease or ALD
Non-alcoholic fatty liver disease or NAFLD
If you are a woman who is pregnant, you can also get fatty liver disease.
Alcoholic Liver Disease (ALD)

You can get ALD from drinking lots of alcohol. ALD can also present itself after a short period of heavy drinking.
Genetics has a role to play in ALD. Genes can make you hit the bottle and increase your chances of becoming an alcoholic.
Genes can also impact the way your body breaks down the alcohol you drink.
Other root causes of ALD are:

Hep C doesn't cause ALD. it is one of the causes of fatty liver. 
Hep B is also a cause of fatty liver. There are certain medications which may be helpful from person to person besides lifestyle management.
Excess iron in your body
Obesity
Non-alcoholic Fatty Liver Disease (NAFLD)
The cause of NAFLD is not clear, but we know that it tends to run in families.
NAFLD is also more common in the middle-aged and the obese or, those who have high cholesterol and diabetes.

Other risk factors are:

Certain medicines
Viral hepatitis
Auto-immune or inherited liver disease
Gaining weight fast
Malnutrition
Acute Fatty Liver during Pregnancy
Fat can build up in your liver when you're pregnant, causing this kind of fatty liver disease.
It s a serious condition as it can be risky for both you and your baby. It can cause liver or kidney failure in you and your child, both.
Causes are unknown. But, hormones may play a role.
Symptoms of fatty liver disease
This disease can sometimes cause no symptoms for long. But, the things to look out for are-

Feeling tired all the time
Loss of appetite or weight
General weakness
Nausea
Confusion and trouble concentrating
Your liver can become larger
Pain in the centre or right upper part of your belly
In ALD, your symptoms get worse after bouts of heavy drinking. Fatty liver disease is diagnosed during routine exams when your doctor notices your enlarged liver. Ultrasound, blood tests to check for certain enzymes and biopsy of the liver are performed to confirm it.

Treatment

There is no specific treatment for the fatty liver disease.
You can manage it by managing your diabetes and giving up drinking. If you have ALD and you don t quit, you get complications like alcoholic hepatitis or cirrhosis.
Even if you have a non-alcoholic fatty liver disease, alcohol cessation helps.
Losing weight if you are overweight also helps to manage this disease and having a good balanced diet with exercise also shows benefits.
