Low lactate dehydrogenase does not need to be treated as long as it is not too low, the patient has no underlying disease, and no symptoms are present. Lactate dehydrogenase is a glycolytic enzyme, and low lactate dehydrogenase may be a result of errors in the examination process, which needs to be reviewed in time. Then there is endocrine disorder, which may lead to low lactate dehydrogenase; also overwork, lack of sleep, bad mood, etc. can lead to low lactate dehydrogenase. Low lactate dehydrogenase is generally not very serious, and can be recovered after conditioning. Avoid overexertion, good sleep habits and good mood, eat less salt and sugar, avoid spicy and stimulating food, and stop smoking and drinking.
