When an adult has a fever without symptoms, it is always a concern, because the temperature as one of the body's reactions does not arise from scratch.However, the absence of any symptoms is frightening, since it is impossible to immediately determine the cause of such a condition.
The optimum temperature index of normally occurring processes in the human body is 36.6 ° C. However, there are times when the temperature is elevated for no reason.
On the one hand, for some people this is the norm: there are people who always have 36, and there are those who have a normal temperature of 37.4 ° C. On the other hand, if a person normally has a normal temperature of 36.6 ° C, a high fever without symptoms in the adult means any disturbance.
Why does elevated temperature occur?
In all other situations, a rise in body temperature above normal indicates that the body is trying to fight something. In most cases, these are foreign agents in the body - bacteria, viruses, protozoa or the consequence of physical effects on the body (burn, frostbite, foreign body). At an elevated temperature, the existence of agents in the body becomes difficult, infections, for example, die at a temperature of about 38 ° C.
All fevers are divided into three groups:
- Subfebrile fever, at which the temperature rises from 37 to 38 degrees;
- Febrile fever- the temperature rises from 38 to 39 degrees;
- Hectic fever- increase in temperature from 40 degrees and above.
But any organism, like the mechanism, is not perfect and can fail. In the case of temperature, we can observe this when the body, due to the individual characteristics of the immune system too violently reacts to various infections, and the temperature rises too high, for most people this is 38.5 ° C.
Causes of high fever in adults without symptoms
A fever or fever is observed in almost all acute infectious diseases, as well as during the exacerbation of certain chronic diseases. And in the absence of catarrhal symptoms, doctors can to establish by isolating the pathogen either directly from a local foci of infection, or from the blood.
It is much more difficult to determine the cause of the temperature without signs of a cold, if the disease has occurred due to exposure to the organism of conditionally pathogenic microbes (bacteria, fungi, mycoplasma) - against the background of a decrease in general or local immunity. Then it is necessary to conduct a detailed laboratory study of not only blood, but also urine, bile, sputum and mucus.
The causes of temperature without symptoms can be associated with the following diseases:
- Endocrine diseases, for example, thyrotoxicosis;
- Systemic inflammation: Crohn's disease, rheumatism, polyarthritis, nodular periarthritis, etc .;
- Oncological diseases: tumors of the stomach, liver, kidneys, bronchi or lungs, lymphoma, leukemia;
- Diseases of fungal, parasitic or viral etiology: syphilis, toxoplasmosis, candidiasis, malaria;
- Infectious diseases: HIV infection, Lyme disease, recurrent and typhus, tuberculosis;
- Inflammatory diseases of bacterial origin: sepsis, inflammation of the uterine appendages, prostatitis, meningitis, sinusitis, tonsillitis, pneumonia, endocarditis, etc.
In all situations, an increase in temperature without signs of cold indicates that the body is trying to fight something. For example, the so-called subfebrile fever, often accompanies anemia - a low level of hemoglobin in the blood.
Is it necessary to bring down the temperature?
It is generally believed that an increase in temperature is a favorable factor, indicating the confrontation of the body with destructive effects. If the thermometer is read to 38.5 ° C, do not panic.
If its growth is observed, then it is necessary to bring down the temperature using antipyretic drugs - Paracetamol, Aspirin... also it is possible to use NSAIDs - Ibuprofen, Nurofen. For children, Nurofen, in the form of a sweet syrup, is best for children, but Aspirin can not be given to a child.
At 42 ° C there are irreversible changes in the cerebral cortex and possibly the onset of a lethal outcome. But this happens rarely.
Temperature 37 without symptoms: possible causes
Runny nose, fever, sore throat are all common symptoms of a common cold. But what to do if the temperature is 37 without symptoms? For whatever reasons this arises and how to deal with it, let's figure it out.
Causes of fever without visible symptoms:
- The onset of pregnancy (in women);
- Weakened immunity;
- Presence of any sluggish infection in the body;
- Pre-catarrhal condition;
- Depletion of human energy reserves;
- General fatigue, depressive or post-stress condition;
- Venereal diseases (syphilis, AIDS, etc.)
Basically, the temperature of 37 without symptoms in an adult is due to the fact that there is some reason that caused such a condition, but she did not completely overcome the defensive powers of man.
Temperature 38 without symptoms: possible causes
A temperature of 38 without symptoms can occur frequently enough. And not always the reasons for this temperature are the same. This temperature can signal that lacunar or follicular angina begins (in catarrhal angina, the temperature rises slightly).
If the temperature above 38 degrees without symptoms lasts 3 or more days, this can be a manifestation:
- Rheumatism;
- Infarction;
- Inflammation of the kidneys (with a strong stitching pain in the lower back);
- Vegetosovascular dystonia accompanied by irregular blood pressure;
- Pneumonia.
The most unpleasant syndrome is the persistence of fever for several weeks and even months. This is most likely:
- Sign of development in the body of a tumor;
- Serious endocrine disorders;
- Leukemia;
- Diffuse changes in the liver or lungs.
The only thing that unites all these cases is that in any case, the increase in temperature is due to the resistance of the body, which means that the immune system is fighting.
Temperature 39 without symptoms: possible causes
If the temperature of 39 without symptoms in an adult does not appear the first time, then this is a clear sign of a pathological decrease in immunity and the development of a chronic inflammatory process. The phenomenon may be accompanied by loss of consciousness, febrile convulsions, shortness of breath or further increase. In this case, you must always go to a medical institution.
A high body temperature of 39-39.5 ° without obvious symptoms may be a signal about the following diseases:
- ARVI;
- The presence of a tumor process;
- Development of catarrhal angina;
- Manifestation of an allergic reaction;
- Chronic pyelonephritis;
- Manifestation of hypothalamic syndrome;
- The presence of viral endocarditis;
- The appearance of meningococcal infection.
Clarifying the reasons for raising the temperature to 39 ° C in adults is a difficult task even for experienced specialists, since to establish the cause it is necessary to isolate the causative agent from the blood or foci of infection.
What to do?
First of all, go to the reception to your therapist. Very often we simply can not notice these or other symptoms, and the doctor can easily identify them and can diagnose the disease. It is also necessary to pass tests, they will help to identify many diseases that do not manifest themselves externally. Sometimes a doctor can prescribe a sputum culture, urine or blood, an x-ray or ultrasound.
It is not recommended to abuse febrifugal. Removing the symptom, you can delay the examination for a long time and start the disease, which, of course, causes harm to health.
If the temperature is very high, it is worthwhile to call an ambulance team, so that the doctors render emergency help and decide the question of hospitalization. In any case, the heat is a "cry" of the body for help, and it should be noted.
