Liver
Cirrhosis Overview
Cirrhosis
is a prognosis of various liver diseases and it is the final stage of
liver fibrosis. However, not all chronic liver diseases will advance to
cirrhosis. For example, only about 20 to 25% of chronic hepatitis C
patients will advance to the cirrhosis stage and it usually takes many
years to do so. This article will provide a general overview of what
happens when a liver disease does develop into the cirrhosis stage.
Cirrhosis
results in liver cell necrosis and fiber (scar) tissue overgrowth. A
healthy, normal functioning liver is made up of trillions of liver cells,
aligned in liver cell plates, which form the functional lobes. In a normal
cell’s life cycle, apoptosis (normal cell death) occurs at a certain point and new
cells replace the dead cells. This cycle maintains the structure and
functionality of the liver. However, if cell death is caused by viral
hepatitis, alcohol, or any other pathological causes, the normal cell
replacement cycle is disrupted and can compromise the structure of the
liver itself. Pathological disorders like hepatitis cause continuous and
abnormally large numbers of cells to die, which eventually results in
collapses of the liver’s reticular-fiber framework. As this happens,
newly regenerated cells lose their normal alignment and form abnormal
lobes. These lobes are non-functional. At the same time, scarring
(fibrosis) occurs to repair the damaged structure of the liver and the
amount of fiber tissue increases greatly. Over time, the culmination of
these changes in the liver eventually leads to cirrhosis.
When
liver cirrhosis progresses, the liver itself becomes hardened and it will
shrink in size while the surface becomes uneven. Liver function
deterioration and portal vein hypertension are the main causes of
pathogenesis. Clinically, there are two stages in liver cirrhosis,
compensated and de-compensated. In the compensated stage, disease
progression is stealthy and shows very few noticeable symptoms. Liver
function tests may show normal enzyme readings and without a biopsy, it is
difficult to identify clinically. During this stage, the most common
symptoms could be fatigue, anorexia, over-frequent thirst, thick coating
on the tongue, nausea, stomach broadness, and dull pains in the liver
area. As liver functions
further deteriorates and the portal vein pressure increases, these
symptoms may worsen. New symptoms and physical signs such as spider moles,
liver palms, liver shrinkage, jaundice, edema, ascites, and low grad fever
could start to show and at this point, the cirrhosis starts to enter the
de-compensated stage.
The de-compensated stage of cirrhosis is the late stage of the chronic
liver diseases and many complications may arise. The most serious
complications are ascites, gastric bleeding, spontaneous peritonitis,
hepatic-renal dysfunction, encephalopathy, and hepatocellular carcinoma
For
patients with cirrhosis, the purpose of Chinese medicinal herbal treatment
is to sustain the stability of the compensated condition and prevent
progression into the de-compensated stage. For those already in the
de-compensated condition, herbal treatment can deal with the various
complications and try to reverse the de-compensated stage back to the
compensated stage. Many patients with cirrhosis are also candidates for a
liver transplant. The waiting period can be long and Chinese herbal
treatment can ensure that the patient is in the best condition possible
before undergoing this major surgical procedure. Patients who are not
suitable for a transplant can maximize their quality of life with an
herbal protocol. In the de-compensated stage, the patient needs many
different types of medical care and we are going to discuss specific areas
of these complications in the coming articles.
