Liver testing for diseases is also carried out during pregnancy (ideally at the planning stage), before surgery and a course of treatment involving the administration of potent drugs.
When can an LFT test be required? It is recommended to regularly examine the most important organs and systems of the body for prophylactic purposes. But there are a number of symptoms that signal that verification is required as quickly as possible. Thus, the liver should be examined immediately if you notice the following signs of organ dysfunction:
Discomfort in the lower pair of ribs on the right is one of the first manifestations of liver problems. Barely noticeable nagging pains, tingling may accompany unusual sensations and a feeling of constriction or overcrowding in the area of the liver. Usually, they make themselves felt when laughing, talking loudly or shouting, sneezing, sharp sideways, lifting weights, as well as after eating fatty, smoked, fried or spicy foods. At first, a new feeling may not cause pain or tangible discomfort- in this case; they also say: “I found out where the liver is.” This is a reason to be wary, because even mild symptoms may indicate the initial stage of the serious hepatic disease.
The liver is enlarged. The change in the dimensions of the main gland is accurately recorded by ultrasound, but you can notice the changes yourself. This will indicate a bulging belly without an increase in overall fullness and with virtually no weight gain. The especially noticeable symptom in people with thin physique.
Unpleasant taste in the mouth. Patients with chronic liver problems have a constant dry mouth and bitterness on the tongue, sometimes with a characteristic flavor that is defined as “copper.” At the same time, an astringent feeling is noted in the mouth; taste sensations are reduced. Habitual food can cause rejection, even nausea and the urge to vomit.
Weight loss on the background of the asthenic syndrome. This symptom is largely a consequence of the previous one. Food rejection, loss of taste, nausea lead to a decrease in diet, which leads to weight loss. At the same time, the patient complains of unreasonable irritability, as well as weakness, drowsiness, fatigue, because the body's energy requirements are not met, and the toxic effects of impaired nitrogenous (protein) metabolism greatly increase- with an increased concentration of ammonia in the blood, secondary (hepatic) hyperammonemia occurs.
Jaundice is a common complex of symptoms, which is expressed in the yellowness of the skin, mucous membranes and whites of the eyes, as well as in dark urine, itching, and peeling of the skin, in chills, bone, and joint pain, and is caused by problems with the liver.
What does a liver function test reveal?
- The fact of the disease, its degree, the level of liver failure;
- The presence and degree of histological (cellular) changes in the structure of the liver tissue, such as fibrosis and cirrhosis of the liver;
- Diagnosis of specific liver diseases - viral and autoimmune hepatitis, fatty hepatosis.
