Intoxication of the liver

человеческая печень The liver performs a large number of functions in the body. One of them is protective. The digestive gland acts as a filter. She passes through her blood, cleaning her from toxins. But what happens to poisons in the body?

Toxins of blood, lingering in the liver, amaze her. Some iron substances neutralize, but with a large dose and strong or regular effects - liver cells die. The harmful effects can be exerted by toxins from various groups. Symptoms of intoxication are very similar. Then how to distinguish between the liver and liver? And, most importantly, how to help a person in this situation?

Causes of liver intoxication

Intoxication of the liver can occur accidentally, during a professional activity or intentionally. Hepatotoxic substances are also called hepatic poisons. How do they get into the human body? The main way is food. There is also a variant of ingestion of poisons through the respiratory system. In this case, they are absorbed into the blood from the lungs. Almost all hepatic poisons cause the death of hepatocytes (liver cells). There are two mechanisms of action of toxins on the liver.

  1. Direct effects on hepatocytes and their death.
  2. Violation of blood circulation in the liver vessels, resulting in cells do not get oxygen, nutrition and die.

What can cause liver poisoning? There are the following hepatic poisons:

  • medications;
  • industrial substances;
  • alcohol;
  • vegetable poisons.

They cause various pathological processes in the liver, but differ in a similar clinical picture.

Drug intoxication of the liver

Medicines, if they are taken in a dose by a certain doctor, have a slight toxic effect. But if the dosage has been greatly exceeded, toxic hepatitis develops.

интоксикация от лекарств The intoxication of the liver with medicines may occur because of the admission:

  • sulfanilamides (Biseptol, Sulfamethoxazole, Sulfasalazine, Sulfacetamide, etc.);
  • antiviral drugs (interferons, Amantadine);
  • drugs for fighting tuberculosis (Rifampicin, Isoniazid, Nevirapine, tetracyclines, Oxacillin);
  • anti-inflammatory and antipyretic agents (Nimesulide, Celecoxib, Sulindac, acetylsalicylic acid, Analgin, Paracetamol);
  • medicines widely used in cardiology (Amiodarone, statins, Labetalol, Methyldopa, Pelentan);
  • drugs for weight loss (Orlistat);
  • antidepressants ("Fluoxetine", "Carbamazepine", "Phenytoin");
  • antifungal drugs (fluconazole, ketoconazole);
  • hormones (anabolic steroids, androgens, estrogens);
  • antitumor agents.

The insidiousness of these poisons is that they can cause both acute poisoning due to taking a large dose of the drug, and hidden as a result of the cumulative effect. A person learns about this already at the stage of fatty degeneration, cirrhosis or massive liver necrosis.

Medicines have different mechanisms of liver damage. Some cause necrosis (death) of hepatocytes, others affect the bile ducts, blocking them, the third - on the vessels, disrupting the trophism (nutrition) of the organ.

Alcohol intoxication of the liver

действие алкоголя на печень

Toxic alcohol poisoning of the liver occurs with excessive consumption of alcohol-containing beverages. It is chronic. That is, a long time is formed. There is also acute massive necrosis of the liver, but it is rare, when consuming very large doses of alcohol at the same time.

Alcohol itself can cause liver poisoning in a dose exceeding 20-30 grams per day. But modern alcoholic products in addition to ethanol and water contain a lot of impurities, which are more dangerous than alcohol itself. It is low-quality alcohol is a frequent cause of liver damage.

Initially, alcohol intoxication is still reversible, and with the cessation of abuse, the function of the liver will gradually recover almost completely. But if people continue to abuse alcohol, then in the body there are irreversible changes.

The fact is that all the alcohol that has entered the blood passes through the liver, where it is converted by the action of the enzyme alcohol dehydrogenase to acetaldehyde. Acetaldehyde has a much greater toxicity than ethanol itself. It not only kills hepatocytes, but also disrupts fat metabolism, causing accumulation of fat in healthy cells. There is fatty degeneration of the liver, and it can not normally perform its functions.

People working in production often encounter substances that have a toxic effect on the liver.

Industrial hepatotropic poisons include:

  • arsenic and its compounds (metallurgy);
  • phosphorus (metallurgical industry, production and use of agricultural fertilizers);
  • pesticides, insecticides (agriculture);
  • oil refining products;
  • aldehydes (chemical, medical industry);
  • phenols (production and use of antiseptics).

Perhaps both acute and chronic liver damage. Chronic intoxication when exposed to small doses happens more often.

Vegetable poisons are represented by alkaloids of the following plants and fungi:

  • heliotrope;
  • the cross;
  • gorchak pink;
  • death cap.

Plant toxins, affecting the digestive gland, cause acute damage.

Symptoms of liver intoxication

The clinical picture of liver intoxication depends on the nature of the poisoning course. There is acute, chronic course and massive necrosis of hepatocytes.

How does liver intoxication manifest?

  1. With chronic poisoning, there may be a lack or minor signs. Liver insufficiency progresses slowly, turning into cirrhosis, and after a few months jaundice, hemorrhages, vascular sprouts, signs of brain damage (impaired memory, attention, decreased mental capacity), ascites (fluid in the abdominal cavity), "jellyfish head" ( expansion of the subcutaneous veins around the navel).
  2. Acute intoxication begins to manifest after 2-3 days. There are cases when it is asymptomatic. It depends on the type of poison and the severity of the poisoning.

Signs of acute liver intoxication:

  • pain in the liver (right hypochondrium);
  • fever to 38-39 ° C, headache, weakness, malaise, joint and muscle pain;
  • nausea, vomiting;
  • bleeding (from the nose, gums when brushing teeth), minor skin hemorrhages, hematomas;
  • encephalopathy (signs of brain damage - excitation or inhibition, impaired coordination, orientation, trembling limbs and head);
  • желтушность склер у человека
    icteric sclera

    icterus of skin and sclera, feces bleached, urine of dark beer color;

  • when palpating the liver, it is felt enlarged, dense, tense and painful.

There is a kind of acute hepatic poisoning - acute massive necrosis of hepatocytes. It is characterized by lightning current, severe symptoms, rapid lethal outcome. Encephalopathy is more pronounced in this pathology, cerebral edema, hypoglycemia, a sharp decrease in blood pressure can develop. Acute massive necrosis of hepatocytes can lead to death within a few days.

Treatment of toxic liver damage

In case of acute hepatic poisoning, you urgently need to seek medical help and be treated exclusively in a hospital. The patient is shown bed rest, special food, detoxification of the liver, use of antidotes, medicines that protect the liver and accelerate regeneration, cholagogue preparations, vitamin therapy.

  5. To drink cholagogue preparations or a collection.

To drugs for detoxification of the liver include: vitamins C, B, "Heptral", "Essentiale", "Holosas", "Holenzyme", "Enterosorb", "Lactofiltrum." If necessary, plasmapheresis, hemosorption, hemodialysis.

Diet with liver intoxication should be observed from the very beginning of the disease and for several months. It is forbidden to drink alcohol, smoke, it is necessary to eat often and in a fractional manner. It is necessary to exclude from the diet:

  • fatty foods;

The liver takes the main blow in the fight against poisons that enter our body. And, although everyone knows that it regenerates and it restores its functionality even with great damage, poisoning can still lead to serious consequences. Symptoms of toxic damage to the main digestive gland are similar for various poisoning factors. Pain in the right upper quadrant, jaundice, nausea, vomiting, fever, hemorrhages - these are the signs of acute hepatitis due to toxins.

Treatment of intoxication is a long process. It should be comprehensive and under the supervision of a doctor. You can use both traditional and folk methods.
