Low alachlor aminotransferase and creatinine are generally not clinically significant and may be due to insufficient protein intake; regular review is recommended. The presence of low GAT and creatinine in a patient during a checkup does not usually indicate a disease, but may be due to insufficient protein intake. Protein will be broken down into amino acids in the body, and GATT will be involved in the metabolism of amino acids, and the end product of protein metabolism will be creatinine, which will be excreted by the kidneys. If the patient’s protein intake is insufficient, the phenomenon of low ghrelin and creatinine will occur. It is recommended that patients add protein-rich foods, such as eggs, beef, fish, chicken, tofu, milk, etc., into their daily diet in moderation to ensure balanced nutritional intake. Patients should consume fresh vegetables in moderation, such as bok choy, celery and winter melon. Patients with low glutamic transaminase and creatinine are generally due to low protein intake, patients should adjust their diet, review on time, and consult the hospital when discomfort occurs.
