Fever is the temporary increase in body temperature and occurs as a defense mechanism of the body to protect itself from bacteria or viruses responsible for the presence of an infection or disease. Therefore, although fever is a symptom that generates general malaise, chills and headaches, it is considered to be a kind of battle that the body is fighting in our favor and not against us.

The causes of fever can be many , but among the most common are respiratory infections (bronchitis or pneumonia), urinary tract infections, flu, gastroenteritis, and sinusitis. Although these conditions do not pose a greater risk to health when properly treated, it is necessary to monitor temperature levels to prevent fever from turning the outlook into a major complication. For this reason, in this FastlyHealarticle we focus on telling you when to go to the emergency room for fever in adults so that you know how to recognize those situations in which this symptom is dangerous.

When is fever in adults?

The first thing to know when to go to the doctor for a fever is to recognize which are the elevated temperature levels that indicate that a person has a fever.

Fever in adults occurs when the body temperature, measured in the armpit, oscillates around 38ºC and is considered a mild fever. Between 37ºC and 37.5ºC it is considered a low-grade fever, the tenths that alert us that the body is beginning to combat a threat.

However, it must be taken into account that as the day passes and night falls, the body temperature usually rises one degree, so the diagnosis of fever can vary depending on the time of day. Also, when a woman is in the second phase of the menstrual cycle, her body temperature is normally one degree higher than usual. Physical activity and emotions such as stress, fear and anxiety can also produce normal variations in temperature that should not be considered a fever.
