Is your thermometer showing "25 again"?The temperature is elevated again, but not that much – no more than 38 degrees, and it has been there for more than one day? And the reason for such an increase is not exactly known to you? Most likely, you have encountered such a phenomenon as subfebrile temperature. This is the issue we will try to understand in this article. However, before talking specifically about subfebrile temperature, it is necessary to have a clear idea of what conditions characterized by an increase in body temperature are distinguished in medicine. Doctors distinguish three such conditions:
Diagnosis is particularly difficult fordoctors is the fact that there are no symptoms of other diseases, and the increase in body temperature may be within the physiological norm. Below we will talk about adequate assessment and diagnostic methods of subfebrile temperature, both in children and adults. In order to understand the problem of subfebrile temperature, you need to be able to measure the temperature correctly and interpret it. At first glance, there is nothing complicated in measuring body temperature. However, a person should check again whether the body temperature is measured correctly. Firstly, the armpit in which the temperature is measured should be completely dry. If a sick person is sweating, it is necessary to carefully remove the sweat and let the skin dry thoroughly. Only after this can you begin to measure body temperature. In addition, there is another problem, which lies directly in the thermometer itself. Almost all people are accustomed to blindly believing the thermometer readings. However, if you see numbers on your thermometer indicating that your body temperature is elevated, but you do not experience any unusual sensations for your body, such as chills, try changing the thermometer first. Re-measure your temperature with another thermometer, preferably one with a fundamentally different design, for example, replace a mercury thermometer with an electronic one, or vice versa. Sometimes this simple measure allows you to save a lot of nerves, and time spent on visiting a doctor.
What is the temperature norm?
It is also important to remember that body temperatureis not a constant value. Temperature varies in different directions, and this is completely normal. But due to the fact that not every person knows about it, any. Even physiological (within one degree) deviation from the norm towards an increase is regarded by a person as an increase in body temperature. However, this is not true at all. It is widely believed that the normal human body temperature is 36 and 6 degrees. However, this is not true - as numerous studies have proven, and practical observations of a huge number of doctors, the most common average body temperature is 37 degrees. However, this figure can change significantly, fluctuating between 35 and 37.5 degrees. These variations depend on several factors. For example, such as the physiological state of the body of each specific person, the level of his physical activity, the state of the hormonal background, the time of day. In addition, such a factor as the environment - the level of humidity, the air temperature in the room - plays an important role in measuring temperature. For any healthy person, daily temperature fluctuations of about half a degree are normal. As a rule, between 4 and 6 o'clock in the morning, a person has the lowest body temperature of the entire day. This feature is clearly seen in illnesses accompanied by a significant rise in body temperature - even the highest body temperature drops significantly in the early morning. But between 4 and 10 p.m., body temperature reaches its maximum. In addition, remember that a woman's body temperature may increase due to hormonal changes in the body that are associated with the menstrual cycle. As a rule, a woman's highest temperature is observed between the 17th and 25th day of the menstrual cycle. Sometimes the figures can reach 38 and 8 degrees. In addition, very often factors such as severe emotional stress and increased physical activity lead to an increase in body temperature. Moreover, this applies equally to both adults and children. For example, body temperature can rise due to stress caused by problems in family life or work, or due to physical exertion. In children, an increase in body temperature can be caused by prolonged crying or overly active physical play. All of these variations described above are physiological norms and do not require any medical intervention in the human body from doctors.
The causes of subfebrile fever
So, as we have already found out, subfebrileDoctors call a temperature a condition of the human body in which the body temperature remains within 37.5 – 38 degrees for a long time. In other words, the body temperature level is above the physiological norm, but below the true fever. Of course, subfebrile temperature does not appear out of nowhere, out of nowhere. There are a number of diseases that make themselves known for a very long time only by the appearance of subfebrile temperature. However, sooner or later these signs will certainly make themselves known, after which it will be much easier for doctors to correctly diagnose the disease that served as the primary cause of the subfebrile body temperature. Doctors distinguish two main groups of diseases that can cause subfebrile temperature:
Diagnosis of the causes of subfebrile temperature
Due to the fact that the temperature is subfebrilecan be caused by a variety of diseases, there is no specific diagnostic method, and there cannot be. However, unfortunately, sometimes the examination does not give any results at all. And in such cases, doctors are forced to diagnose primary hyperthermia. In any case, in order to find out the cause of the disease, a person must consult a doctor - a therapist. The doctor will prescribe a number of necessary studies - a general and biochemical blood test, urine analysis, ultrasound examination of all internal organs, blood test for hormones. And based on the results of the study, the doctor will prescribe the necessary treatment for the sick person. We recommend reading:
