When a person's fever rises, it means that there is inflammation in the body - that's what most people think. However, not always the inflammation becomes the reason of a subfebrile condition - also in it the hypothalamus, a hypophysis and vegetative nervous system can be guilty.
Causes of low-grade fever in women
The female body undergoes a lot of changes throughout the cycle-an increase in the content of certain hormones and a decrease in the number of other hormones. This change may be accompanied by a slight increase in temperature during menstruation.
Another reason for the subfebrile condition in women is pregnancy.
Subfebrile temperature after ARI
If after an acute respiratory viral infection the subfebrile temperature remains, it means that the organism has not yet overcome the viruses, and the struggle for health continues even in the absence of symptoms. In this case, you should consult LOR - the specialist will check the condition of the nose and throat, and if necessary, assign an analysis to the microflora of the throat to determine the number of bacteria or viruses. Normally, the temperature in ARVI should not persist for more than 5 days - if it keeps, then it means that complications arose that require detailed diagnosis and quality treatment.
Causes of prolonged subfebrile temperature
The reasons for a constant low-grade fever can be varied - from the stresses experienced to severe violations of thermoregulatory organs.
Subfebrile temperature in case of neurosis
If you believe psychologists and psychiatrists, today very many people suffer from a neurosis of varying severity. This leads to various pathologies, to determine the nature of which is difficult enough - for example, perspiration in the throat can be treated with antiviral medications, and the cause of it will not be a virus, but nerves. Also things are the same with the temperature - if you notice irritability, sleep disturbance, anxiety, and others complain of sharp reactions from your side, and there is a subfebrile temperature, then this speaks in favor of the fact that the subfebrile condition is held against the background of neurosis.
Subfebrile temperature with IRR
If the subfebrile temperature rises in the evenings, then this may indicate an exacerbation of the AVI . This diagnosis includes a wide range of symptoms, and therefore to determine the cause in the form of VSD is possible only after a complete examination of the body.
Subfebrile temperature in case of disruption of the pituitary and hypothalamus
The hypothalamus and pituitary gland are responsible for raising and lowering the temperature. This means that an unreasonable subfebrile condition may indicate that these parts of the brain are not working properly. In such cases, it is necessary to pass tests for hormones, as well as an MRI to exclude tumor diseases.
Subfebrile temperature in chronic infectious diseases
Very often the cause of subfebrile temperature are chronic infections of the throat and urogenital system. If you have chronic tonsillitis or cystitis, then it is likely that the harmful flora has activated, and the bacteria have again led to an exacerbation, which the body tries to fight by raising the temperature.
Subfebrile temperature after pneumonia
After inflammation of the lungs, there may be a subfebrile temperature, o
Treatment of low-grade fever
Treatment of subfebrile temperature depends on what caused it. Temporary increase in temperature in women does not require treatment, and if this is due to chronic diseases, then complex treatment should be performed: for example, cystitis and tonsillitis show antibiotics.
If the temperature rises with a neurosis or VSD, then it is necessary to take antihistamines, and in severe cases - antidepressants or tranquilizers.
