Amylase generally refers to serum amylase, the normal reference value is between 0-150U/L, if a small amount of high may be physiological reasons, if it is more than twice as high, it may be due to pancreatic disease or mumps, etc., need to be vigilant. 1. Physiological reasons: generally after eating, the serum amylase level in the human body will rise significantly, which belongs to the normal physiological response, if it is only transient and not accompanied by other physical discomfort, generally do not need special treatment. 2. Pathologic causes: (1) Pancreatic diseases: for example, pancreatitis, when the pancreatic fluid discharge is blocked, resulting in amylase reflux into the bloodstream, which will trigger the serum amylase in the body to appear elevated. (2) Purulent parotitis: As the parotid gland secretes saliva, which contains amylase digestive enzymes, when the parotid gland develops purulent inflammation, because the function of the parotid gland is affected, it will lead to amylase entering into the bloodstream, causing elevation of serum amylase. When the serum amylase is abnormal, it is recommended to consult a doctor, follow the doctor’s instructions for further examination, clarify the cause with the help of the doctor, and carry out targeted treatment.
