Introduction
If rectal and oral temperatures consistently remain at 37.2°C without any other discomfort, it is usually caused by normal physiological factors. However, if axillary temperature consistently remains at 37.2°C, it may be due to pathological causes such as upper respiratory tract infection or hyperthyroidism. In such cases, patients can take medications like moxifloxacin hydrochloride tablets or nimesulide granules under the guidance of a physician.
If the rectal and oral temperatures consistently remain at 37.2°C without any other discomfort symptoms, it is usually caused by normal physiological factors. However, if the axillary (underarm) temperature consistently remains at 37.2°C, it may be due to pathological causes, such as upper respiratory tract infection or hyperthyroidism. Specific details are analyzed below:
1. Physiological Factors
The normal range for rectal temperature is 36.9–37.9°C, while the normal oral temperature range is 36.3–37.2°C. Therefore, if the temperature measured rectally or orally consistently reads 37.2°C and no other symptoms are present, this is typically a normal physiological phenomenon that does not require special treatment.
2. Pathological Factors
1) Upper Respiratory Tract Infection
The normal axillary temperature range is 36.1–37°C. A consistent axillary temperature of 37.2°C indicates slightly elevated body temperature, possibly suggesting underlying inflammation. If the patient is overly fatigued or exposed to cold, their immune system may weaken, allowing pathogens to invade and trigger an upper respiratory tract infection. This condition may manifest in such mild fever during the early stages. It is recommended that patients follow medical advice and take medications such as moxifloxacin hydrochloride tablets or nimesulide granules for treatment.
2) Hyperthyroidism
If a patient has abnormal overactivity of the thyroid gland, excessive production of thyroid hormones can accelerate metabolism and increase blood flow, leading to elevated body temperature. This may result in persistently higher readings such as 37.2°C. It is recommended to follow a doctor's instructions and use medications such as metoprolol tartrate tablets or methimazole tablets for treatment.
Besides the above conditions, persistent low-grade fever could also be caused by systemic lupus erythematosus, leukemia, lung cancer, or other diseases. It is advisable to consume more fresh vegetables and fruits in daily life and engage in moderate physical activity to enhance immunity. If additional symptoms develop, prompt medical evaluation is recommended, followed by appropriate diagnosis and treatment under medical supervision.
