When you read those articles...this might help you understand them better:
(1)steato or lipids means fat
(2)hepat or hepato means liver
(3)itis at the end of the word...means inflammation
(4)cirrhosis is the scarring of the liver
NASH means nonalcoholic steatohepatitis or using the words above...it means a fatty liver with inflammation not caused by alcohol consumption.
NAFLD means nonalcoholic fatty liver disease
Steatosis liver or also known as simple fatty liver
There is fatty liver where the fat accumulates on the "outside" of the liver. To me this is steatosis liver or simple fatty liver.
This doesn't usually cause a problem with the liver cells. It doesn't go on to cause damage either.
There is a fatty liver where fat accumulates in the liver, between the liver cells. This is when a problem occurs. That fat can push against the cells and also block nourishment and oxygen to the cells. This is definitely a problem. A person who loses weight, in this case, may decrease the amount of fat and help the cells to heal. However, if the fat is there for a long period of time...then our immune system steps in and causing inflammation to occur. This just adds to the problem...as the liver may start to swell from the inflammation and cause the cells more damage from the pressure against them.
There is also the problem with people who consume alcohol. The fat comes from the constant intake of this alcohol. By stopping drinking, this can sometimes be reversed.
Inflammation inside the liver caused by alcohol, being overweight, and other things can be treated with medications and the
stopping of consumption of certain things.
However, if the inflammation stays there...it can lead to death of the liver cells...which shows up as fibrosis and then scar tissue.
When the liver cells die and this scar tissue is formed inside the liver....it also does damage. As it also blocks blood flow and communication between the cells and basically, it starves the cells of nourishment and oxygen and those once healthy cells that were left, die off also and it keeps progressing as more scar tissue develops inside the liver. This is known as cirrhosis.
I've mentioned alcohol, being over weight,
but there are other things that can cause a fatty liver:
(1) from having viral hepatitis or ,in other
words, liver inflammation caused by a virus
that a person developed.
(2) autoimmune hepatitis...this is where the body own immune system attacks the liver causing inflammation.
(3) an over accumulation of copper in the body.
(4) a metabolism problem where the body has difficulty breaking down the fats we eat.
(5) certain drugs can contribute to it...like prednisone which is a steriod, if it is taken in high amounts for long periods.
(6) genetic defects
(7) diabetes,insulin resistance.
If you have this disease, it all depends on how much damage it has done to the liver to develop symptoms. What I list below may or may not pertain to every patient.
(1) right upper quadrant abdominal pain.
This may be due to the stretching of the
outward stretching of the membrane that surrounds the liver.
(2) if the inflammation isn't reduced, then the liver cells may lose there functions and then symptoms like jaundice, which is the yellowing of the whites of the eyes and skin will occur. There may also be loss of appetite, fatigue, nausea, vomiting and confusion.
(3) if cirrhosis should develop where the cells of the liver die...which isn't always the case in people who have fatty livers but can occur: then they may have an abdominal enlargement caused by the lack of a protein that usually holds liquid in our vessels but now it seeps into the abdomen...this is known as Ascites They may also have difficulty with their memory and become easily confused, because the toxins that the liver once handled is now entering the blood and going pass the blood brain barrier and into the brain...this is known as encephalopathy. There are a number of things that occur as symptoms with patients who have cirrhosis. Cirrhosis is also caused by many different things and not just a fatty liver.
I hope this helps you know more about this disease
