Why can 0 1 alanine aminotransferase represent liver health?
Alanine aminotransferase (ALT) can preliminarily detect the health status of liver because it is one of the essential physiological substances in liver cells.
In other words, all liver cells have alanine aminotransferase. If our liver is healthy and normal, and the liver cells are intact, alanine aminotransferase naturally cannot enter the human environment through the wall of liver cells. Therefore, the content of alanine aminotransferase in normal people is very low at the time of examination.
However, if a large number of liver cells are necrotic due to some external factors, alanine aminotransferase can easily enter the human environment through the cell wall. The increase of alanine aminotransferase in the body during examination may also indicate that there are too many liver cells necrotic and there may be liver abnormalities.
But then again, although the increase of transaminase can predict the abnormal situation of liver, whether it can confirm the existence of liver disease in this group of people remains to be discussed.
I once met a case in which a young man came for a physical examination. His height is 179 and his weight is 72kg, which should be a very well-proportioned figure standard.
But at the time of examination, the level of transaminase in the young man was as high as 1 10. Does this result really mean that the young man has liver disease?
02 transaminase is as high as 1 10, does it mean that there must be liver disease?
Here, the doctor will share with you the health standard of transaminase level:
Under normal circumstances, a healthy transaminase numerical index should be below 40, between 30 and 40.
And this young man's transaminase has reached 1 10, and there are some physical problems more or less. Let's analyze them one by one.
If transaminase rises, there may be common pathological reasons:
① There may be hepatitis B symptoms.
I believe everyone is familiar with hepatitis B. After hepatitis B virus invades the human body, it will not attack in a short time. When the virus replicates completely and accumulates too much, it will stimulate the liver, cause hepatocyte necrosis, and then cause various liver diseases.
It is also the characteristic that hepatitis B virus can kill liver cells, which leads to the loss of a large number of transaminase into the body environment, and the transaminase value of patients with hepatitis B is often very high. It is also used as a standard for the initial diagnosis of hepatitis B.
Fusang bean-the "nemesis" of hepatitis B.
According to Zhang Zhongjing's Qian Jin Fang, Fusang bean is extracted from Ginseng, Rosa roxburghii, Lycium barbarum, Cordyceps militaris, Crataegus pinnatifida, Ginseng, Concha Canadensis, Hippophae rhamnoides, Inulin and Kudingcha, which has the functions of protecting liver, promoting gallbladder function (lowering enzymes), calming the nerves, helping sleep and strengthening the spleen and stomach, and can also help prolong life if taken for a long time.
Modern research has found that it is rich in selenium, polysaccharide and saponin active substances, which can not only improve human immunity and repair damaged liver cells in a short time, but also effectively prevent alcoholic hepatitis and fatty liver, inhibit liver fibrosis and cirrhosis, and have a good therapeutic effect on hepatitis A, hepatitis B and chronic hepatitis.
② There may be hidden dangers of fatty liver.
The function of the liver in the body, in addition to storing blood and maintaining blood circulation, is also responsible for the metabolic function of fat in the body.
If you have fatty liver, it means that the liver's ability to metabolize fat is insufficient. Over time, a large amount of fat gathered around the liver, which stimulated the liver to produce inflammation, and also led to the death of some liver cells, which in turn increased the level of transaminase in the body environment.
On the other hand, we see that this young man, with a figure of 179/72, has a very low probability of suffering from fatty liver. After a simple hepatitis B antigen test in the hospital, no symptoms of hepatitis B were found.
It is enough to see from here that even if the body's transaminase level rises, it is not necessarily a hidden danger of liver disease. There are also objective reasons.
What are the common objective reasons for the elevation of transaminase?
(1) The behavior of staying up late before physical examination.
When we sleep, the organs of the body will enter a state of self-repair. If you stay up late rashly, the time for self-repair will be shortened, and the organs may be uncomfortable.
This is particularly evident in the liver. As a daily metabolic organ, the liver often contains residual fat and toxins, which is very necessary for sleep self-healing. If you stay up late for a long time, the liver will not regulate itself and toxins will accumulate, which will threaten the health of some liver cells.
Because of this, if you stay up late before the physical examination and consume too many liver cells, it will also lead to an increase in transaminase.
② Take medicine before physical examination.
Most drugs are toxic, and the reason why they are harmless to our health is that the liver can carry out toxic metabolism of drugs and eliminate the hidden dangers that may be brought to the body by taking drugs.
So when we take medicine, the liver metabolizes toxins, which will inevitably consume some liver cells. When the transaminase in these liver cells flows out, there will be a deviation in the healthy value of transaminase.
There are other objective factors, such as overeating and lack of exercise, which may lead to a temporary increase in transaminase, and then there will be numerical deviation in physical examination. This is why doctors always ask for fasting or not taking medicine before physical examination.
Generally speaking, as long as the alanine aminotransferase level does not exceed twice the normal value, that is, 120u/l, and there are no obvious symptoms in the body, it is impossible to be 100% sure that there is liver disease. It is not comprehensive to judge whether there are symptoms of liver disease only by the increase of transaminase. Before making a thorough diagnosis, further examination is needed to find out the definite liver lesions.
But then again, if the transaminase is high during the physical examination, it proves that there are some problems in life and health, and it is necessary to adjust the living habits in time.
Friends with high transaminase, if you adjust your daily habits to nourish and protect your liver?
Doctor's advice: Remember "Three Don 'ts".
1) Don't stay up late. Staying up late will disturb the metabolism of the body and shorten the repair time of the liver. Over time, liver toxins will accumulate and the probability of natural liver disease will increase.
2) Don't smoke and drink. Smoking and drinking will increase the burden of metabolic toxins in the liver. After a long time, the working ability of the liver will decline, the health level will weaken, and it is more prone to disease problems.
3) Don't get angry often. Long-term negative emotions will also affect the cellular activity of the liver, reduce the working efficiency of the liver, and then lead to the long-term accumulation of toxins, threatening the health of the liver. Therefore, it is very important to learn to regulate self-emotion in daily life.
