Causes of fever with temperature fluctuations
If you are not free of fever at any time, but your body temperature fluctuates up to 2° Celsius during the day, then the medical term for this is a remitting fever. Usually the temperature is lower in the morning after waking up and reaches its peak in the evening. The causes can be varied, for example, remittent fever occurs in the case of influenza or blood poisoning (sepsis). An infection with bacteria or viruses often leads to a remitting fever.
Causes of fever with no fever
You have been to the tropics? In Africa? And now you have a fever?
If you are free of fever for 1-2 days, you must always suspect malaria. If it is one day without fever, this indicates a malaria tertiana, if it is 2 days without fever, it could be malaria quartana. The dreaded Malaria tropica does not have a typical fever course and is usually characterized by an irregular fever spread.
Other tropical diseases can also lead to fever, which should be taken into account if you have been in a risk area. High fever is also a symptom of the deadly disease Ebola. Malaria and Ebola are life-threatening infectious diseases.
If you have the slightest suspicion of an infection, you should visit a doctor immediately. Malaria and Ebola are life-threatening infectious diseases. If you have the slightest suspicion of an infection, you should see a doctor immediately.
Measuring fever correctly
The most accurate temperature can be measured in the ear or rectally
How does fever develop?
The mechanism by which fever develops is very complex and will only be described here in a simplified form. In a region of the brain called the hypothalamus, there are nerves that are about 30% heat-sensitive; one part is insensitive to temperature and one part is sensitive to cold. All nerves are in contact with each other and thus set the standard value of the body temperature.
This equilibrium can be upset by so-called pyogenes, resulting in an increase in temperature. If there is an increase in temperature, the heat-sensitive nerves fire faster and a further increase in temperature occurs.Pyogens are therefore fever-inducing substances or substances of various kinds. Foreign bodies and externally supplied pathogens (viruses, bacteria, particles) as well as substances produced in the body (various inflammatory messengers that are released by the body in the event of an inflammation) are among these pyogens. If these substances are released, the body temperature (fever) is raised very soon through various biochemical intermediate steps.
