Gallstones - Causes, Symptoms, Laboratory Examinations, Therapy, Diet

Cholestasis is a condition in which the secretion of bile into the duodenum is inhibited or reduced through various mechanisms. Bile components are also retained in liver cells, and these changes are accompanied by an enlargement of the bile ducts. Bile stasis can be a standalone disease, but also a symptom of a severe liver disorder. It is worth noting that cholestasis can cause jaundice, but cholestasis should not be confused with jaundice – jaundice is only one of the potential symptoms of cholestasis.

Hepatological pathologies related to bile secretion obstruction are classified as those that involve anatomical or functional difficulties in the development of bile, or secondary to hepatocyte (liver cells) damage. Cholesterol causes various factors that may otherwise be grouped into mechanical, chemical, and genetic factors. Mechanical-based disease is divided into intra-yellow or peripheral diseases. The classification is also based on the location of the bile ducts. Whole-cell partial blockage of the flow of amino acids into the bile and bile duct can cause bile vomiting in the bile. The flow can be blocked, for example, by the growth of a tumor. In addition, a bile stasis that is located outside the liver can be caused by non-passage of the bile ducts. The most commonly affected is the common bile duct, where the cause for the condition may be, for example, bile stones or pressure from outside, originating from a tumor. Chemical causes of cholestasis include disorders related to the excretion of regulatory substances such as hormones, inflammatory mediators, and bile acids. Some medications may also exhibit cholestatic activity. Genetic causes of cholestasis may be caused by errors in the synthesis of bile acids. However, the diagnosis of cholestasis can sometimes be complicated if there are disorders related to the hepatic clearance of bile acids from the blood. Among the causes of cholestasis are also various disorders related to the metabolism of amino acids, carbohydrates, or lipids.

The most characteristic symptom of biliary tract inflammation is jaundice, which indicates an increased concentration of yellow pigments in the blood. The rise in these pigments is due to the lack of bile flow from the liver to the duodenum, causing them to infiltrate other tissues. If jaundice persists for a prolonged period, the skin may develop a grayish-green tinge. This occurs due to the conversion of bilirubin into biliverdin, which is a metabolite of bilirubin and imparts a characteristic color. Unfortunately, deposited bile acids have a toxic effect on hepatocytes. A concurrent symptom is persistent itching of the skin caused by the irritation of nerve fibers responsible for pain sensation. Furthermore, there are disturbances in the digestion and absorption of lipids in the gastrointestinal tract and fat-soluble vitamins, primarily A, D, and K. Symptoms may also involve the kidneys and cardiovascular system. There is also often a discoloration of stool accompanied by a darker tint in urine. Rare symptoms of cholestasis include the formation of jaundice nodules - clustered lumps on the skin.

In cholestasis, elevated levels of certain blood components used for bile production under normal conditions are observed. These include bile acids - bilirubin and alkaline phosphatase (base, ALP), although the latter does not allow for differentiation between bile retention and other diseases. The increased concentration also affects transaminases (AspAT, AIAT), the enzyme GGTP (gamma-glutamyltransferase), but also cholesterol and copper. Imaging studies may show an enlarged liver, and in some cases, also an enlarged spleen.

Cholesterol diagnosed during pregnancy is a condition that typically resolves on its own after the birth of the child. Its development may have various causes, and researchers emphasize the significant role of genetic predispositions and other factors such as ethnic background (more common in women of Latin American descent, for example) or co-occurring nutritional deficiencies. A symptom that usually accompanies the diagnosis of cholesterol is itchy skin that begins in the third trimester for most expectant mothers. This symptom typically occurs in the evening and at night, which can affect sleep quality. The itch usually develops gradually, initially affecting the skin on the hands and feet, and in severe cases, the entire body may be affected. Unfortunately, these symptoms often lead to scratching and other skin changes in patients. Diarrhea is a rare occurrence in the course of pregnancy cholesterol. Although the described condition is usually not life-threatening for the woman, it can be dangerous for the developing fetus. Excess bile acids accompanying pregnancy cholesterol may contribute to premature birth, heart problems in the fetus, and even fetal death. In the case of pregnancy cholesterol, the occurrence of the condition itself increases the risk of recurrence of the disease in subsequent pregnancies, and more severe symptoms are observed upon re-diagnosis.

There is no universal method for treating cholestasis, as the approach depends on the cause of the bile stasis. Early initiation of treatment is particularly crucial, especially in newborns and small infants. Unfortunately, cholestasis can rapidly lead to irreversible damage to the liver and bile ducts in this age group. Metabolic disorders can be the underlying cause of the bile stasis, and if not dealt with appropriately, can lead to psychomotor retardation in children. Therefore, swift diagnostic intervention and appropriate action are necessary to avoid such consequences. There are about thirty units of diet-dependent diseases arising from improper nutrition and lack of physical activity.

The cholesterol diet should be properly balanced and easily digestible. In the case of cholesterol stasis, adequate supply of fat-soluble vitamins A, D, E and K is necessary. If, despite proper dietary balancing, the supply of these components is not adequate, the supplementation of oral supplements should be taken into consideration. Although vitamin A in excess demonstrates the necessary performance, an adequate intake of fat-soluble vitamins is required. If the dose of these components does not reach a satisfactory level despite proper dietary balancing, the supplementation of oral supplements should be taken into consideration. Due to lipid absorption disorders in cholesterol stasis, fatty diarrhea may occur. In this state, it is necessary to reduce the fat intake in the diet. However, it is important to choose the amount of fat properly with other macronutrients to reduce the risk of undernutrition. The use of oils in the raw state and the preparation of easily digestible dishes are also recommended. These are better tolerated and can be a source of NNKT (non-saturated fatty acids). Preparations containing MCT (medium chain triglycerides) are especially recommended for children. These are absorbed in the digestive tract without the participation of bile acids. Research also provides information on the positive effect of essential phospholipids (EPL). Liver diseases usually require special attention to the quality and caloric intake of the diet, as diseases of this organ often lead to weight loss and even pose a risk of undernutrition. An important aspect is also alcohol consumption. If it is one of the factors that caused the primary disease - the cause of cholesterol stasis, it should be abandoned (even in small amounts generally considered safe). Separate dietary recommendations will apply to children with metabolic diseases diagnosed as the cause of cholesterol stasis. In such cases, the introduction of appropriate elimination diets may be necessary. Cholesterol stasis is a state in which correct diagnosis is of the utmost importance. It is essential to determine the cause of the bile stasis in order to implement appropriate treatment.
