Do you have a thermometer again 25? Again the temperature is raised, but not too much - no more than 38 degrees, and it is holding on far not the first day? And the reason for such an increase is not known for certain? Most likely, you are faced with such a phenomenon as subfebrile temperature. It is in this issue and try to understand this article. However, before telling about the subfebrile temperature, it is necessary to have a precise idea of which states characterized by an increase in body temperature are distinguished in medicine. Such conditions the doctors distinguish three:
Particular difficulty in diagnosing forphysicians represent the fact that the symptoms of other diseases are absent, and an increase in body temperature may be within the physiological norm. Below we will talk about an adequate assessment and methods for diagnosing subfebrile temperature, both in children and in adults. In order to understand the problem of subfebrile temperature, it is necessary to be able to correctly measure the temperature and interpret it. At first glance, there is nothing difficult in measuring body temperature. However, a person should check again whether the body temperature is measured correctly. First, the axilla in which the temperature is measured should be completely dry. If the sick person sweats, carefully remove sweat and allow the skin to dry properly. Only after this, you can begin to measure body temperature. In addition, there is another problem, enclosed directly in the thermometer itself. Almost all people are accustomed to believe the thermometer indefinitely. However, if you see figures on your thermometer that the body temperature is increased, and you do not experience any unusual sensations such as chills, try to change the thermometer first. Measure the temperature with another thermometer, and preferably with a fundamentally different design, for example, replace the mercury thermometer with an electronic thermometer, or vice versa. Sometimes this simple measure allows you to save a lot of nerves, and even the time spent on visiting a doctor.
What is the temperature norm?
It must also be remembered that body temperature is notis a constant. The temperature varies in different directions, and this is perfectly normal. But due to the fact that not everyone knows about this, any. Even physiological (within one degree) deviation from the norm in the direction of increase is regarded by a person as an increase in body temperature. However, this is not so. It is widely believed that the normal temperature of the human body is 36 and 6 degrees. However, this is not the case-as numerous studies have proved, and even practical observations of a huge number of physicians, the most common average body temperature is 37 degrees. However, this figure can change significantly, ranging from 35 to 37.5 degrees. These variations depend on several factors. For example, such as the physiological state of the organism of each individual person, the level of his physical load, the state of the hormonal background, time of day. In addition, the factor that plays a significant role in temperature measurement is the environment - the humidity level, the air temperature in the room. In any healthy person, diurnal 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 for all days. This feature is well traced in a disease accompanied by a significant rise in body temperature - even the highest body temperature is greatly reduced in the early morning. But in the interval 16 - 22 hours the body temperature level reaches its maximum. In addition, remember that a woman's body temperature increase is possible because of those hormonal changes in the body that are associated with the course of the menstrual cycle. Typically, the highest temperature in a woman is noted between the 17th and 25th day of the menstrual cycle. Sometimes the numbers can reach 38 and 8 degrees. In addition, very often, such factors as strong emotional stress, increased physical activity lead to an increase in body temperature. And 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, due to physical stress. In children, the increase in body temperature can be caused by prolonged crying or overly active physical games. All these above-described variations are the physiological norm, and do not require any medical intervention in the human body by physicians.
The causes of subfebrile fever
So, as we have already explained, subfebriletemperature doctors call such a state of the human body, in which the body temperature for a long time is kept within 37, 5 - 38 degrees. In other words, the body temperature level is more physiological norm, but below the true fever. Of course, subfebrile temperature does not arise from nowhere, from scratch. There are a number of diseases that for a very long time only occur after the appearance of subfebrile temperature. However, sooner or later, these signs will certainly make themselves felt, after which it will be much easier for physicians to correctly diagnose the disease, which was the primary cause of 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 subfebrile temperaturecan be caused by a variety of diseases, there is no specific diagnostic method, and it can not be. However, unfortunately, sometimes the survey does not give any results. 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 should consult a therapist. The doctor will appoint a number of necessary studies - a general and biochemical blood test, urinalysis, ultrasound examination of all internal organs, a blood test for hormones. And based on the results of the study, the doctor will appoint the patient the necessary treatment. We advise you to read:
