Liver and Liver Disease

Uncategorized

Hepatitis is kind of disease that infects your liver. This caused by viruses, toxins and drugs. We know hepatitis A and hepatitis B as liver diseases. Hepatitis A is contagious through food and saliva, hepatitis B is contagious through injection needles, blood transfusions, mother to fetus, etc. we can heal these diseases completely by good medication and the right therapies. With the latest  diagnostic testing facilities we can observe the symptoms and determine the best diet to prevent these diseases when the diseases is at the minimum level. The medium-high level of these diseases is liver cancer, that is really not an easy situation at all and it’s  hard thing to overcome.

The early prevention is to have a appropriate diet for your liver. Start in an easy way, try to have fruit juice as your daily menus. Carrots and grapes are good for your liver. Remember that medical therapies are more exhausting than this. We have to start protecting ourselves than try to make money and we waste it for repairing our precious bodies. Hospital is the best option to cure diseases, and stay healthy is our priority.

The liver is a vital organ present in vertebrates and some other animals; it has a wide range of functions, a few of which are detoxification, protein synthesis, and production of biochemicals necessary for digestion. The liver is necessary for survival; there is currently no way to compensate for the absence of liver function. The liverplays a major role in metabolism and has a number of functions in the body, including glycogen storage, decomposition of red blood cells, plasma protein synthesis, hormone production, and detoxification. The liver is also the largest gland in the human body. It lies below the diaphragm in the thoracic region of the abdomen. It produces bile, an alkaline compound which aids in digestion, via the emulsification of lipids. It also performs and regulates a wide variety of high-volume biochemical reactions requiring highly specialized tissues.

Medical terms related to the liver often start in hepato- or hepatic from the Greek word for liver,

Liver Anatomy

An adult human liver normally weighs between 1.4-1.6 kg (3.1-3.5 lb), and is a soft, pinkish-brown, triangular organ. Averaging about the size of an American football in adults, it is both the largest internal organ and the largest gland in the human body (not considering the skin).

It is located in the right upper quadrant of the abdominal cavity, resting just below the diaphragm. The liver lies to the right of the stomach and overlies the gallbladder.

Liver Blood Flow

The liver receives a dual blood supply consisting of the hepatic portal vein and hepatic arteries. Supplying approximately 75% of the liver’s blood supply, the hepatic portal vein carries venous blood drained from the spleen, gastrointestinal tract, and its associated organs. The hepatic arteries supply arterial blood to the liver, accounting for the remainder of its blood flow. Oxygen is provided from both sources; approximately half of the liver’s oxygen demand is met by the hepatic portal vein, and half is met by the hepatic arteries.
Blood flows through the sinusoids and empties into the central vein of each lobule. The central veins coalesce into hepatic veins, which leave the liver and empty into the inferior vena cava. it occupies most of the right+ hypochondriac region,epigastric region and left hypochondriac region

Liver Biliary Flow

The bile produced in the liver is collected in bile canaliculi, which merge to form bile ducts. Within the liver, these ducts are called intrahepatic bile ducts, and once they exit the liver they are considered extrahepatic. The extrahepatic ducts eventually drain into the right and left hepatic ducts, which in turn merge to form the common hepatic duct. The cystic duct from the gallbladder joins with the common hepatic duct to form the common bile duct. The term biliary tree is derived from the arboreal branches of the bile ducts. The intrahepatic bile ducts form the most distant branches of this tree.

Bile can either drain directly into the duodenum via the common bile duct or be temporarily stored in the gallbladder via the cystic duct. The common bile duct and the pancreatic duct enter the duodenum together at the ampulla of Vater.

Liver Surface Anatomy

Peritoneal Ligaments
Apart from a patch where it connects to the diaphragm (the so-called “bare area”), the liver is covered entirely by visceral peritoneum, a thin, double-layered membrane that reduces friction against other organs. The peritoneum folds back on itself to form the falciform ligament and the right and left triangular ligaments.

These “ligaments” are in no way related to the true anatomic ligaments in joints, and have essentially no functional importance, but they are easily recognizable surface landmarks.

Liver Lobes
Traditional gross anatomy divided the liver into four lobes based on surface features. The falciform ligament is visible on the front (anterior side) of the liver. This divides the liver into a left anatomical lobe, and a right anatomical lobe.

If the liver flipped over, to look at it from behind (the visceral surface), there are two additional lobes between the right and left. These are the caudate lobe (the more superior), and below this the quadrate lobe.

From behind, the lobes are divided up by the ligamentum venosum and ligamentum teres (anything left of these is the left lobe), the transverse fissure (or porta hepatis) divides the caudate from the quadrate lobe, and the right sagittal fossa, which the inferior vena cava runs over, separates these two lobes from the right lobe.

Liver Functional Anatomy

The central area where the common bile duct, hepatic portal vein, and hepatic artery proper enter is the hilum or “porta hepatis”. The duct, vein, and artery divide into left and right branches, and the portions of the liver supplied by these branches constitute the functional left and right lobes.

The functional lobes are separated by an imaginary plane joining the gallbladder fossa to the inferior vena cava. The plane separates the liver into the true right and left lobes. The middle hepatic vein also demarcates the true right and left lobes. The right lobe is further divided into an anterior and posterior segment by the right hepatic vein. The left lobe is divided into the medial and lateral segments by the left hepatic vein. The fissure for the ligamentum teres also separates the medial and lateral segments. The medial segment is also called the quadrate lobe. In the widely used Couinaud (or “French”) system, the functional lobes are further divided into a total of eight subsegments based on a transverse plane through the bifurcation of the main portal vein. The caudate lobe is a separate structure which receives blood flow from both the right- and left-sided vascular branches. Saving for your health care with payday advance

Liver disease may not show any symptoms at first, as symptoms can be vague. This includes weakness and loss of energy.

Other symptoms include jaundice that is a disease of the gall bladder. Jaundice is one of the main symptoms of liver disease. Jaundice can turn the skin color to yellow. Another symptom is related to digestion and appetite. Poor appetite is a very common symptom. It leads to loss of weight and anemia. Along with this vomiting, nausea or diarrhea can also manifest.

Another important symptom is light colored stool. Due to the lack of bile production, the stool will appear light and can be gray colored or pale.

Distention and bloating can be considered as another symptoms to watch out for and can cause a pain during breathing.

Polyuria or excess urination and polydypsia or excess thirst are the other symptoms typical of the liver disease.

Liver cancer has symptoms that include weight loss and loss of appetite. Abdominal pain, nausea and vomiting, fatigue, accumulation of fluid in the abdomen, enlarged liver, change of color (yellowing) of the skin and the whites of the eyes are also noticed. Bile duct obstruction has symptoms like pale stools, dark urine, abdominal pain, jaundice, vomiting, nausea and fever.

Portal hypertension that is a high blood pressure in the portal veins has no symptoms. But complications due to this disease can result in bloody vomiting and black, loose stools from varices, ascites; and signs of brain disease called encephalopathy.

Alcoholic liver disease has symptoms like loss of appetite, nausea, swollen abdomen, jaundice, abdominal pain, ascites, weight gain, mental confusion, excessive thirst, dry mouth and fatigue. Additional symptoms include vomiting blood or black, paleness, light-headedness or fainting, fluctuating mood and altered level of consciousness. saving monet with fast cash for your health in the future.

There are many different types of liver disease. But no matter what type you have, the damage to your liver is likely to progress in a similar way.
Whether your liver is infected with a virus, injured by chemicals, or under attack from your own immune system, the basic danger is the same – that your liver will become so damaged that it can no longer work to keep you alive. Anything that keeps your liver from doing its job may put your life in danger.

The Healthy Liver

Your liver helps fight infections and cleans your blood. It also helps digest food and stores energy for when you need it. A healthy liver has the amazing ability to grow back, or regenerate, when it is damaged. Anything that keeps your liver from doing its job – or from growing back after injury – may put your life in danger.

Liver Inflammation

In the early stage of any liver disease, your liver may become inflamed. It may become tender and enlarged. Inflammation shows that your body is trying to fight an infection or heal an injury. But if the inflammation continues over time, it can start to hurt your liver permanently.
When most other parts of your body become inflamed, you can feel it – the area becomes hot and painful. But an inflamed liver may cause you no discomfort at all. If your liver disease is diagnosed and treated successfully at this stage, the inflammation may go away.

Liver Fibrosis

If left untreated, the inflamed liver will start to scar. As excess scar tissue grows, it replaces healthy liver tissue. This process is called fibrosis. (Scar tissue is a kind of fibrous tissue.)

Scar tissue cannot do the work that healthy liver tissue can. Moreover, scar tissue can keep blood from flowing through your liver. As more scar tissue builds up, your liver may not work as well as it once did. Or, the healthy part of your liver has to work harder to make up for the scarred part. If your liver disease is diagnosed and treated successfully at this stage, there’s still a chance that your liver can heal itself over time.

Liver Cirrhosis

But if left untreated, your liver may become so seriously scarred that it can no longer heal itself. This stage – when the damage cannot be reversed – is calledcirrhosis. Cirrhosis can lead to a number of complications, including liver cancer. In some people, the symptoms of cirrhosis may be the first signs of liver disease.

  • You may bleed or bruise easily.
  • Water may build up in your legs and/or abdomen.
  • Your skin and eyes may take on a yellow color, a condition called jaundice.
  • Your skin may itch intensely.
  • In blood vessels leading to your liver, the blood may back up because of blockage. These blood vessels may burst.
  • You may become more sensitive to medications and their side effects.
  • You may develop insulin resistance and type-2 diabetes.
  • Toxins may build up in your brain, causing problems with concentration, memory, sleeping, or other mental functions.

Once you’ve been diagnosed with cirrhosis, treatment will focus on keeping your condition from getting worse. It may be possible to stop or slow the liver damage. It is important to protect the healthy liver tissue you have left.

Liver Failure

Liver failure means that your liver is losing or has lost all of its function. It is a life-threatening condition that demands urgent medical care.
The first symptoms of liver failure are often nausea, loss of appetite, fatigue, and diarrhea. Because these symptoms can have any number of causes, it may be hard to tell that the liver is failing.

But as liver failure progresses, the symptoms become more serious. The patient may become confused and disoriented, and extremely sleepy. There is a risk of coma and death. Immediate treatment is needed. The medical team will try to save whatever part of the liver that still works. If this is not possible, the only option may be a liver transplant. When liver failure occurs as a result of cirrhosis, it usually means that the liver has been failing gradually for some time, possibly for years. This is called chronic liver failure.  Chronic liver failure can also be caused by malnutrition. More rarely, liver failure can occur suddenly, in as little as 48 hours. This is called acute liver failure and is usually a reaction to poisoning or a medication overdose.

Cirrhosis, liver cancer, and liver failure are serious conditions that can threaten your life. Once you have reached these stages of liver disease, your treatment options may be very limited.

That’s why it’s important to catch liver disease early, in the inflammation and fibrosis stages. If you are treated successfully at these stages, your liver may have a chance to heal itself and recover.
