Low-grade fever without symptoms

What is subfebrile temperature

When a thermometer detects a steady increase in performance from 37.1 to 38 ° C - it is a subfebrile condition. It develops as a result of inflammatory processes, intoxication, allergies, hormonal disorders, breakdowns of thermoregulation of central genesis, and ionizing effects. A low-grade fever that can last for a week is accompanied by most respiratory infections, much longer it will be observed with inflammation of the digestive and urinary tracts.

When the causes of moderate hyperthermia are clear( for example, influenza, pancreatitis, cystitis, tonsillitis), it is treated in combination with other symptoms and normalizes with recovery. The absence of obvious signs of the disease requires examination, since a long period of subfebrile, unlike temperature 37 without symptoms, cannot be physiological, it will definitely be explained. One cannot limit oneself to observation and expectation of improvement; a convincing argument is the frequent low-grade temperature in oncology, which cannot be started.

Temperature 37 - what to do. Why the temperature lasts 37 for a long time, the reasons for the increase in
. How much does the temperature in a child and an adult.
  • . Normal human body temperatureNormally occurring metabolic processes heat the human body from 35.5 to 37.4 ° C, this range is considered physiological. Thermal control is carried out by the hypothalamic structures of the brain, supplied with thermal receptors. The slightest cooling or overheating of the internal environment of the body causes a signal that causes the thyroid gland to correct hormone production and normalize the basal metabolic rate.

    • How to measure

    correctly Thermometry can be carried out with mercury or electronic thermometers, equally accurate and reliable. The lack of the first - the duration of the measurement( 8-10 minutes), the fragility, the toxicity of the filler( mercury).The measurement is carried out in the armpit, oral cavity, anus. A mercury thermometer must first be shaken off, knocking the bar down to the 35 ° C mark. Electronic thermometers often show inaccurate parameters, because before you trust them, you should check the indicators with those that gives the usual mercury.

    Causes of asymptomatic temperature rise up to 37 degrees

    Physiological fluctuations in thermoregulation are possible with significant physical, emotional, mental stress. The main difference from the disease process is a satisfactory general condition. It is necessary to find out why the temperature holds 37. Sometimes it is reasonable to change the schedule and pace of work, to rethink the attitude to problems. However, minor hyperthermia can manifest terrible diseases that occur hidden, with scanty symptoms - tuberculosis, infections of the genitourinary system, many helminth infections, viral pathology.

    Temperature in children with bronchitis - why it lasts for a long time and how to knock off at homeIf a man or woman is looking for a thermometer - there is a reason. Malaise, fatigue, easy chills, other barely noticeable symptoms will help determine the source of discomfort. The girl will find out that this condition occurs before menstruation or on the day of ovulation, the guy compares hyperthermia with prolonged exercise, muscle pain. These cases are short-term violations, but how to be when the temperature 37 stays a week or a month?

    It is necessary to carefully analyze the previous changes in one's own state, the appearance of hyperthermia( temperature).It is possible that an operation was performed, an injury occurred, the healing processes in the body can be the cause of a prolonged moderate temperature increase. The presence of chronic diseases( symptoms) requires the exclusion of exacerbations, the development of complications, comorbidity. Temperature 37 without symptoms shows hormonal changes in the body.

    In a child

    Mobility, activity, and emotionality with imperfect thermoregulation explain in part why the temperature in a child without symptoms occurs often. Other causes of hyperthermia are excess clothing that contributes to overheating, stuffiness, prolonged exposure to the sun, excessive bathing. When a child is 10 years old, he is able to understand and take into account the instructions, at 6 years old the child is more affected by the influence of external factors, the newborn entirely depends on the care of adults. Ignorance of the features of a small organism is a frequent cause of hyperthermia - temperature rise up to 37.

    Minor hyperthermia is often accompanied by the eruption of a new tooth, the introduction of complementary foods, even excitement on the eve of a significant event for a child. Vaccination, which promotes the development of immunity, increases the temperature - a natural beneficial reaction, although it scares parents. An assessment of the child’s general condition, his sleep, his appetite, his desire to play, and walk will help calm down.

    One should be wary when the temperature( hyperthermia) without other symptoms is retained for a long period - the case requires the advice of a specialist. Flowing hidden disease inhibits the immune system, causes harm to the body gradually, imperceptibly. Often, diseases of the urogenital tract, infections caused by cytomegalovirus, herpes simplex are manifested in a similar way. Without treatment, a sharp aggravation, complicated course of the disease is possible.

    What to do and when it is worth contacting a doctor

    The main task during hyperthermia( temperature) is to avoid the progression of the disease, the development of undesirable symptoms, a further rise in temperature. A thorough examination of the body, analyzes will reveal the hidden signs of pathology, start treatment in a timely manner. After a course of therapy, it is desirable to be observed by a specialist until full recovery. It is better to rejoice at the absence of serious symptoms and disorders than to skip them, so a visit to the doctor at a temperature cannot be superfluous.

    Video about the causes of subfebrile without visible symptoms

    Minor hyperthermia, exceeding the upper index of physiological thermoregulation( 36.9 ° C), but not reaching the lower limit of the subfebrile condition( 37.1 ° C) is a narrow interval of the temperature scale, which is higher than the norm, but lower than the apparent pathology. Prolonged or frequent disruptions of the thermal status of the body should be alerted - they are manifestations of the disease. Short-term temperature of 37 without symptoms will be justified under all sorts of exertion, emotional outbursts, occurs during periods of age-related reorganizations of the body.
