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.

ALCOHOLIC HEPATITIS

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 bodyThe 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.

Function Of The Liver In Your Body

Liver is one of our body's major and most essential organs. Liver is situated behind the lower ribs on the right side of your abdomen and it's about the size of a football, weighs 3 to 4 pounds. It performs hundreds of essential functions. Without it, you couldn't digest food and absorb nutrients, get rid of toxic substances from your body or stay alive. Hep Forte offers nutritional support for overall liver health, particularly in cases of : Alcoholism, Hepatic dysfunction due to hepatoxic drugs and liver poisons. Without liver, you couldn't digest food and absorb nutrients, get rid of toxic substances from your body or stay alive.

The liver offer your body with critical functions like filtering blood, reducing toxins and producing factors that help blood clot. It serves as a storage depot for sugar (glucose), which it releases when you need energy. Your liver also works as a chemical factory, producing many substances that perform vital tasks in your body. For examples include bile, a fluid that carries away waste and helps digest fat in the small intestine, and cholesterol, a substance needed by every cell in your body. It deals with many drugs into forms that are easier for the body to use. It also converts sugar into triglycerides (lipids/fats) and glycogen (a form of glucose/sugar stored by the liver) that helps regulates the body's needs.

What can be improper with your liver?

As with all organs of the body, the liver is subject to a range of disorders and diseases. Severe complications may be happens if you develop any liver problem. Some liver problems can't be prevented, such as those that are hereditary, but you can take an active part in preventing other liver problems. The liver's functioning does not really decrease with age so, in the absence of disease, the liver should work optimally right into very old age.

The extensive diseases of the liver are viral hepatitis and alcoholic liver disease.

Viral hepatitis - Viral hepatitis can conduct to serious liver problems and is the most common type of liver disease. Hepatitis causes inflammation of the liver. Hepatitis A, B and C are the most common sources of viral hepatitis. As Hepatitis A is customarily a transient infection, both Hepatitis B and C can be serious and progress to chronic liver disease, even causing liver cirrhosis or liver cancer.

Liver Cirrhosis can be due to any long-term, continuous cause of liver damage. These causes include Hepatitis B and C and inherited liver disease. When the liver is wounded some of the running cells die and are replaced by scar tissue. Once cirrhosis has developed, the process cannot be reversed even if the original cause recovers.

Alcoholic liver disease - Alcoholic liver ailment does not affect each person who drinks alcohol. Though it is dependent on the amount of alcohol consumed over time, some people seem to be more susceptible to the adverse effects of alcoholic beverages. Too much alcohol can make a normal liver swell with fat, causing a condition called fatty liver. If the fat becomes inflamed, it can lead to either alcoholic hepatitis, a liver problem that causes serious but often reversible liver damage, or cirrhosis, which causes irreversible liver damage. Because of extensive scarring, a cirrhotic liver shrinks to a fraction of its normal size.
