How to Successfully Combat a Fatty Liver

Fatty liver is a special condition which is characterized by the build-up of fat on the underlying tissues of the liver, which becomes a health concern and risk. This build-up of fat occurs gradually, but seems to proceed rather quickly in obese individuals or people with abnormal weight.

In most cases, the build-up is unnoticeable and without symptoms, but later the manifestation of the condition becomes evident after symptoms start emerging. This condition can be managed effectively if early diagnosis is made and treatment follows immediately.

Cirrhosis: Risk of Liver Damage

Liver is one of the very important organs of body that participates in carrying out many important functions to sustain life of an individual. It can be affected with any disease or disorder and one of the commonest one includes cirrhosis.

Cirrhosis is a type of chronic liver disease where the liver tissue is being replaced by fibrosis, scar tissue and regenerative nodules that result in loss of proper functioning of this vital organ.

Alcoholism, fatty liver, hepatitis B and C are the major factors that are responsible for this chronic liver disease but other factors may also play minor role for example, viral infection, accumulation of toxic metals like iron and copper due to genetic disease and autoimmune disease.

Some idiopathic factors also contribute to liver cirrhosis.

Poor quality of life with increased risk of infection is basically responsible for the appearance of one of the most common complication of this disease identified as ascites. Hepatic encephalopathy and esophageal varices are other complications associated with cirrhosis. This chronic condition is generally irreversible and in advanced cases liver transplant is the only solution.

The term cirrhosis actually originated from a Greek word meaning diseased liver. René Laennec gave the term cirrhosis in 1819 while carrying out his work.

 

Liver is a very essential organ of human body as it carries out many critical functions out of which two are very important for example, it participates in the clotting of proteins in order to stop bleeding and it also aids in the removal of toxic materials like drugs that may be harmful for the human body.

It also partakes in regulating the regular supply of body fuels namely glucose and lipids. In order to perform these essential functions the liver cells must work properly and must be able establish a close connection with blood so that substances can be easily transported as well as removed from blood via liver. The relationship of liver with blood is a unique one. Arteries supply a very small amount of blood to the liver.

Major blood supply of liver actually comes from the intestinal veins as the blood returns to heart. The main vein that returns to heart from intestine is the portal vein. As this portal vein passes through liver it breaks up into smaller and smaller veins. The smallest veins are in close intimacy with the liver cells. This close relationship between the liver cells and the veins helps in addition as well as removal of materials from blood.

The liver cells also line up along the whole length of the sinusoids and when the blood passes through these sinusoids blood is collected in larger veins that collectively combine and form a larger single vain known as the hepatic vein that in turn finally returns to the heart.

 

In liver cirrhosis this intimate relationship between liver cells and blood is destroyed. The liver cells that survive or are newly formed may be able to add or remove substances to blood but their normal functioning is hampered so they no longer are able to maintain the close relationship with blood.

Formation of scars also hampers the regular blood flow from liver to the liver cells as result the pressure in the portal vein increases and the condition is known as portal hypertension. The second major problem caused by cirrhosis is disturbance in the relationship between the liver cells and the channels through which the bile flows. Bile is a fluid that is produced by the liver cells and it has two important functions for example, it helps in digestion as well as removal and elimination of toxic substances.

The bile produced by the liver cells is secreted into very tiny channels that run between the liver cells and also line the sinusoids known as canaliculi. These canaliculi empty into smaller ducts that open into larger ducts. Finally all these ducts open into a single duct that opens in the intestine. So in this way the bile entering the intestine aids in digestion.

At the same time the toxic substances present in the bile also enter intestine and are eliminated out from the body through feces. In cirrhosis, the canaliculi become abnormal and the relationship between the liver cells and these canaliculi is destroyed so the liver cells are not able to eliminate the toxic substance out from the body and they keep on accumulating inside the body. Digestion of food in the intestine is affected but on minor scale.

 

The symptoms of cirrhosis either develop due to the chronic liver disease or are the result of complications of cirrhosis. Many symptoms crop up which have no relation with cirrhosis. The chief symptoms include spider angiomata where vascular lesions develop that can be identified by a central arteriole surrounding many smaller vessels. This condition crops up because of higher secretion of estradiol.

Palmer erythrema is another symptom where altered sex hormone metabolism results in speckled mottling of palm. Changes in the nail structure also appear for example, Muehrcke’s lines identified by paired horizontal lines that are separated by normal color and this condition crops up due to hypoalbuminemia. Apart from this symptom the proximal two-thirds of the nail plates become white with one third portion red in color and this is also due to hypoalbuminemia.

This condition is known as Terry’s nails. Clubbing nails may also result where the angle between the nail plate and the proximal nail fold is greater than 180. Chronic proliferative periostitis of the long bones result in severe pain and the clinical condition is given the term hypertrophic osteoarthropathy. Dupuytren’s contracture can be characterized by thickening and shortening of the palmar facia resulting in the deformities of fingers.

This symptom is very common in 33% patients of liver cirrhosis. Benign proliferation of the tissue male of male breasts can also occur due to excessive secretion of estradiol known as gynecomastia and is common in 66% cases.

Hypogonadism characterized by impotence, infertility, loss of sexual drive and testicular atrophy may also occur due to suppression of the pituitary function. Liver may be enlarged, normal or shrunken.

Portal hypertension results in splenomegaly where the size of spleen is becomes very large than the normal. Accumulation of fluid in the peritoneal cavity results in the formation of ascites. In the portal hypertension the umbilical vein may be open and abnormality may result in a condition known as caput medusa.

Liver Damage Symptoms and Liver Function Tests

The Liver

 

The liver is a very tolerant organ and there is little evidence to suggest that it has an ageing problem such that, without disease, it can function properly into old age. However because most liver disease does not show symptoms and, when it does, the symptoms are often vague, many people with varying degrees of liver damage remain unaware of their liver problems.

 

There are over one hundred types of liver disease and collectively they affect some two million people in the UK. (Of course, this figure may be much higher as many cases of disease remain undiagnosed.) The liver, being so resourceful, is often able to work well enough even when it may be damaged. This means that you may not necessarily display obvious symptoms, or signs of liver disease or illness.

 

What the liver does

 

The liver is situated on the right hand side of your body just below the rib cage. It is the largest gland, and the largest solid organ in the body, weighing some 1.8 kgs in men and 1.3 kgs in women. It holds approximately 13% (about one pint or 0.57 litres) of your total blood supply.

 

The liver is dark reddish-brown in colour and is divided into two main lobes. About 60% of the liver is made up of liver cells called hepatocytes which absorb nutrients and detoxify and remove harmful substances from the blood. The liver is a hard working organ and carries out 1000s of functions per day, including:

 

Cleansing the blood

Helping regulate blood sugar

Metabolising fats

Synthesizing Vitamin A

Breaking down toxic substances.

Storing iron for the body

The Liver and Alcohol

Most people think that alcohol is fairly harmless and something to be enjoyed. Other than a few ill effects the next day, and maybe putting on a bit of weight, alcohol may not seem to have any long lasting effects, but it can.

Alcohol is the major cause of death in the UK and recent research suggests that drinking even slightly more than the recommended amount can cause significant liver damage.

 

Types of Liver Disease

 

Drinking too much alcohol can lead to three types of liver conditions – fatty liver, hepatitis, and cirrhosis. Any, or all, of these conditions can occur at the same time in the same person.

 

A build-up of fat occurs within liver cells in most people who regularly drink heavily. In itself, fatty liver is not usually serious and does not cause symptoms. Fatty liver will usually reverse if you stop drinking heavily.

 

Hepatitis means inflammation of the liver. The inflammation can range from mild to severe.

 

Mild hepatitis may not cause any symptoms. The only indication of inflammation may be an abnormal level of liver enzymes in the blood which can be detected by a blood test.

 

A more severe hepatitis tends to cause symptoms such as feeling sick, jaundice (yellowing of the skin caused by a high level of bilirubin – a chemical normally metabolised in the liver), generally feeling unwell, and sometimes pain over the liver.

 

A very severe bout of alcoholic hepatitis can quickly lead to liver failure.

 

Cirrhosis is a condition where normal liver tissue is replaced by scar tissue (fibrosis). The scarring tends to be a gradual process. The scar tissue affects the normal structure and re-growth of liver cells.

Liver cells become damaged and die as scar tissue gradually develops. So, the liver gradually loses its ability to function well. The scar tissue can also affect the blood flow through the liver which can cause ‘back pressure’ in the blood vessels which bring blood to the liver.

 

Liver Function Tests

 

A liver function test tests for damage to liver cells by testing for two enzymes, ALT and AST. Normally these enzymes are largely present inside liver cells. However, damage to the liver can cause more ALT and AST to leak into the blood. Therefore, raised levels of these enzymes can be an important indicator of liver damage.

 

A liver function test is also suitable for anyone that is concerned about their alcohol consumption, overweight, or on long term medication.

 

The test is an easy to use, finger prick blood test which is confidential too as it can be taken in the comfort of your home.

 

By using a mail order postal service there is no need to visit a specialist or laboratory.

 

Reputable suppliers of liver function tests offer clinically validated liver enzyme tests with laboratory test results.
