Feverishness - what is that?
Subfebrile condition is a physiological sign of mobilizing the body to fight the disease. The temperature range that is covered is considered to be 37.1 oC - 37.9 oC. If there are higher values, above 38 degrees, we will be dealing with a fever. These values, of course, refer to properly carried out measurements taken under the armpit. When measuring the temperature in the oral cavity or anus, we will talk about the subfebrile state when the measured values exceed respectively: 37.5oC and 38, oC.
Let's remember, however, to do it carefully when taking the temperature, for the allotted time and avoid accidental mistakes. Speaking of errors, it should be borne in mind that the temperature of the human body can be influenced by, among others time of day, hot or cold bath, exercise or ambient temperature. To avoid them, try to make measurements to eliminate the impact of these factors, and thus the possibility of adulteration of the measured values.
What can be the causes of a subfebrile condition?
It should be remembered that a low-grade fever is not a disease in itself. It is only a symptom that can occur in the course of many disease states. It accompanies various bacterial and viral infections, hormonal disorders, and sometimes is the first symptom of more serious health problems, e.g. cancer. Among the most common causes of the occurrence of subfebrile condition include:
- Hyperthyroidism- in its course, patients have an elevated body temperature due to the acceleration of metabolism and additionally complain of constant feeling of heat.
- Rhinitis (runny nose) - although it is not always accompanied by a subfebrile condition, if it occurs, it usually lasts up to several days, or it may be a harbinger of a more serious infection and eventually feverish.
- Sinusitis - elevated temperature often coexists with this common ailment and can be a reason for feeling worse.
- Bronchitis - initially body temperature is elevated only within the subfebrile state, but gradually increases, reaching high values attributed to fever.
- lymphomas - in this case, recurrent low-grade fever may be the first and only one symptom of the disease for a long time.
- Lyme disease - in addition to its characteristic symptoms, long-term subfebrile conditions can be observed in its course.
- A brain tumor - elevated temperature may appear suddenly and persist for a long time. Particularly characteristic in this case are the coexisting morning vomiting.
Fever may not only be a sign of infection or other more serious disease, e.g. cancer. It can also occur in the course of physiological processes occurring in the body. In correctly menstruating women, the subfebrile condition occurs every month during ovulation, which is used, among others for determining the so-called "Fertile days."
Should we fight fever?
The subfebrile condition is a physiological process, which means it does not require treatment. However, it is important to regularly monitor the changing temperature values. So that you can react in time if the temperature begins to rise rapidly.
If you exceed 38 degrees, however, you do not need to immediately resort to pharmacological agents. You can as well cope with too high body temperature at home. Cool (but not cold) compresses can be a great way. It can also be helpful. cooling bath. It is worth preparing a bath at a temperature 4 degrees lower than the current body temperature.
However, remember that in cases where we are dealing with a high fever (over 40 degrees) for your own safety seek advice about your own health and how to properly deal with a doctor.
Although the subfebrile condition sometimes makes us feel bad, one should not fight it with pharmacological agents. It is enough to monitor the measured temperature values so that in the event of a fever you can intervene.
