Fever in Adults: What to Know

What is Fever in Adults?

Fever in adults means your body temperature is higher than normal. Usually, a normal body temperature is about 98.6°F (37°C). However, it can vary a little from person to person. If your temperature goes above 100.4°F (38°C), it is considered a fever. Often, fever is a sign that your body is fighting an infection. Sometimes, it can be caused by other health problems. Because fever in adults can have many causes, it is important to know when to seek help.

Common Symptoms of Fever

Besides a high temperature, fever in adults can cause other symptoms. For example, you may feel tired or weak. In addition, you might notice changes in how you feel throughout the day. Here are some common signs:

  • Chills or shivering
  • Sweating
  • Headache
  • Muscle aches
  • Loss of appetite
  • Feeling very tired
  • Dehydration (dry mouth, less urine)
  • Sometimes, you may also have a cough, sore throat, or stomach pain. These can help your doctor find the cause of your fever.

    Causes of Fever in Adults

    Many things can cause fever in adults. Most often, it is due to an infection. However, there are other reasons as well. Here are some common causes:

  • Viral infections (like the flu or COVID-19)
  • Bacterial infections (such as urinary tract infections or pneumonia)
  • Heat exhaustion
  • Inflammatory conditions (like arthritis)
  • Side effects of medicines
  • Vaccines
  • Sometimes, fever can be a sign of a more serious illness. Therefore, it is important to watch for other symptoms.

    How is Fever Diagnosed?

    Doctors usually check your temperature with a thermometer. They may also ask about your symptoms and recent activities. For example, they might ask if you have traveled or been around sick people. In some cases, your doctor may order blood tests or urine tests. These tests can help find the cause of your fever. If needed, they may also do a chest X-ray or other scans.

    Treatment Options for Fever

    Most fevers in adults go away on their own. However, treatment can help you feel better. Here are some common options:

  • Drinking plenty of fluids
  • Resting as much as possible
  • Taking fever-reducing medicines like acetaminophen or ibuprofen
  • Sometimes, you may need antibiotics if you have a bacterial infection. But, antibiotics do not work for viral infections. Always follow your doctor’s advice before taking any medicine.

    There are simple steps you can take at home to manage fever. For instance, you can:
