Lactic acidosis is a pathological condition characterized by a significant accumulation of lactic acid in the body, which leads to metabolic acidosis. This condition can be caused by various factors, including hypoxia, infectious processes, heavy physical exertion, and metabolic disorders. Lactic acidosis is characterized by an increase in the concentration of lactic acid in the blood, which can lead to a violation of the acid-base balance and cause serious complications, including cardiovascular disorders, headache, confusion, and in severe cases, coma and death. Effective management of this condition requires timely diagnosis and a comprehensive approach to treatment.
History of the disease and interesting historical facts
The history of lactic acidosis research goes back to the early 20th century, when the role of lactic acid in human and animal metabolism was first described. In 1923, physician and biochemist Hans Creville, studying the main metabolic processes, drew attention to the accumulation of lactic acid in the blood under certain pathological conditions. Later studies continued to develop this topic, and in the 1960s, lactic acidosis became a recognized clinical syndrome. Modern advances in medical biochemistry and physiology have allowed a deeper understanding of the mechanisms of lactic acidosis development and its relationship with other conditions, which is important for timely diagnosis and treatment.
Epidemiology
According to various epidemiological studies, the overall prevalence of lactic acidosis (particularly extrabacterial) ranges from 2% to 10% among hospitalized patients. In intensive care units, this figure can reach 20-30%. Lactic acidosis is more common in patients with cardiovascular diseases, diabetes, renal failure, and severe infectious processes. Most often, this condition is observed in older patients, which is associated with multiple concomitant diseases and age-related changes in metabolism.
Genetic predisposition to this disease
To date, there is limited research on the genetic predisposition to lactic acidosis. However, there is evidence that certain genetic mutations may influence the risk of developing this condition. For example, abnormalities in genes involved in lactate metabolism, such as LCT (the gene encoding lactase) and other genes involved in carbohydrate and acid metabolism, may predispose to the development of lactic acidosis. In addition, in cases of hereditary lactic acidemia, the condition may worsen in family members with similar genetic features.
Risk factors for the development of this disease
Risk factors for the development of lactic acidosis include:
- Use of alcohol and drugs.
- Heavy physical exertion or depletion of the body's resources during prolonged exertion.
- Uncontrolled diabetes mellitus, especially in case of ketoacidosis.
- Infectious diseases such as pneumonia, sepsis or meningitis.
- Cardiovascular failure and shock of various origins.
- Chronic renal failure and other metabolic disorders.
Diagnosis of this disease
Diagnosis of lactic acidosis begins with a thorough clinical examination and history taking. The main symptoms to look out for include:
- Weakness and fatigue.
- Fever and hypotension.
- Confusion or changes in behavior.
- Chest pain and difficulty breathing.
Laboratory tests needed for diagnosis include measurement of blood lactate levels, blood pH, and electrolytes. Radiologic tests may be ordered to identify possible causes of lactic acidosis, such as pneumonia or thromboembolism. The differential diagnosis includes ruling out other causes of metabolic acidosis, such as ketoacidosis, renal failure, and other conditions that cause similar changes in acid-base balance.
Treatment
Treatment of lactic acidosis requires a comprehensive approach and depends on its cause. Initially, it is important to stabilize the patient's condition, which includes restoring fluid volume and normalizing metabolic processes. Pharmacological treatment may include the use of sodium bicarbonate to correct the acid-base balance in severe acidosis. In some cases, emergency surgery may be required if lactic acidosis is caused by mechanical factors, such as vascular occlusion. The use of antibacterial agents is necessary in infectious processes.
List of medications used to treat this disease
- Sodium bicarbonate - to correct acidosis.
- Antibiotics - in case of infectious genesis.
- Insulin - for diabetic ketoacidosis.
- Medicines for the correction of electrolyte disturbances.
- Drugs to support cardiovascular function.
Disease monitoring
Monitoring a patient with lactic acidosis involves regular monitoring of lactate levels, blood pH, and other metabolic parameters. The prognosis depends on the cause of lactic acidosis, the speed of its diagnosis, and the initiation of treatment. With timely intervention, most patients recover without serious consequences. However, long-term lactic acidosis can lead to serious complications such as renal failure, cardiovascular disorders, and sepsis.
Age-related features of the disease
Lactic acidosis in elderly patients may be more complex, due to the presence of concomitant diseases and decreased organ function. In children, lactic acidosis often occurs as a result of congenital metabolic disorders, as well as severe infectious diseases. In young people, the condition may be associated with excessive physical activity or alcohol abuse, which often leads to rapid diagnosis and treatment.
Questions and Answers
- What causes lactic acidosis? Lactic acidosis can be caused by a variety of factors, including infections, metabolic disorders, strenuous exercise, and alcohol intoxication.

- How is lactic acidosis diagnosed? Diagnostics include checking lactate levels, blood pH, and assessing the condition of internal organs through laboratory and radiological studies.
- How is lactic acidosis treated? Treatment includes fluid replacement, correction of acid-base balance, and treatment of the underlying disease that caused lactic acidosis.
- What is the prognosis for patients with lactic acidosis? The prognosis depends on the cause and severity of lactic acidosis. With timely diagnosis and treatment, most patients recover.
Advice from Dr. Oleg Korzhikov
Lactic acidosis can be a serious condition, and prevention is key and requires little effort. Key recommendations include:
- It is important to monitor your exercise levels and avoid becoming overly exhausted.
- Check blood sugar levels regularly for diabetics and take prescribed medications.
- Avoid alcohol and drug abuse.
- Maintain water balance, especially in hot conditions or during intense physical activity.
By taking care of your health, you can avoid serious complications associated with lactic acidosis and other diseases.
