Is 38.5 degrees a fever in an adult?

Fever is a common symptom that can be caused by many different reasons, such as infections, inflammations or other diseases. In adults, fever is usually defined as a body temperature above 37.5-38.0 degrees. But what does it mean if an adult has a fever of 38.5 degrees? Is that a cause for concern? In this article, we will discuss this question in more detail.

What is fever?

Fever is the body’s natural reaction to help fight infections. It is a sign that the immune system is working and trying to fight pathogens such as viruses and bacteria. During a fever, the body temperature rises, which makes the environment unfavorable for many pathogens.

Definition of fever in adults

In adults, fever is usually defined as follows:

  • Low-grade fever: 37.5-38.0 degrees
  • Moderate fever: 38.1-39.0 degrees
  • High fever: over 39.0 degrees

A fever of 38.5 degrees in an adult therefore belongs to the moderate fever category. This is not necessarily a reason to panic, but it can be a sign that there is an infection or inflammation in the body.

When to see a doctor?

Although a fever of 38.5 degrees is usually not dangerous, there are some situations in which you should see a doctor:

  1. The fever lasts more than three days.
  2. Fever is accompanied by other serious symptoms, such as chest pain, breathing difficulties, severe headache, stiff neck or rash.
  3. You are pregnant or have a chronic illness such as diabetes or heart disease.
  4. You have recently traveled to an area where serious infections such as malaria or dengue have occurred.

Fever treatment

The treatment of fever usually includes rest, adequate hydration and, if necessary, the use of fever-reducing medicines such as paracetamol or ibuprofen. It is also important to monitor body temperature regularly and take care of general well-being.

Summary

A fever of 38.5 degrees in an adult is a moderate fever, which can be a sign of infection or inflammation. Although it is usually not dangerous, it is important to monitor the symptoms and see a doctor if necessary. Treatment for fever includes rest, hydration and, if necessary, fever-reducing medicines.
