laktátszintje

Laktátszintje refers to the concentration of lactate in the blood. Lactate is a molecule produced by the body during anaerobic metabolism, which occurs when cells do not receive enough oxygen to produce energy through aerobic respiration. This typically happens during intense physical activity, but can also be a sign of various medical conditions.

Under normal resting conditions, blood lactate levels are usually low, typically between 0.5 and 2.2 millimoles per liter (mmol/L). When a person engages in strenuous exercise, the muscles begin to produce more lactate as they work harder and their oxygen supply becomes limited. This leads to a temporary increase in blood lactate levels. As exercise intensity decreases, the body's oxygen supply improves, and the liver can convert lactate back into glucose, bringing the levels down.

Elevated laktátszintje, also known as hyperlactatemia, can indicate underlying health problems. Conditions such as sepsis, shock, certain medications, liver disease, and some genetic disorders can impair lactate metabolism or lead to excessive production, resulting in higher-than-normal blood lactate concentrations. Measuring laktátszintje is a common diagnostic tool in clinical settings to assess tissue oxygenation and evaluate the severity of certain diseases. Persistently high levels often require further medical investigation to determine the cause.
