Is a low-grade fever serious?


A low-grade fever is generally not considered serious on its own and may be a normal response to an infection or other medical condition. A fever is defined as a temporary increase in body temperature above the normal range of 97.7-99.5°F (36.5-37.5°C). A low-grade fever is usually defined as a body temperature between 99.5°F (37.5°C) and 100.4°F (38°C).

Low-grade fevers are often caused by viral or bacterial infections, but they can also be caused by other medical conditions such as autoimmune disorders, inflammatory conditions, or reactions to medications. In most cases, a low-grade fever will resolve on its own within a few days without treatment.

However, if a low-grade fever is accompanied by other symptoms such as severe headache, chest pain, difficulty breathing, rash, or confusion, it may be a sign of a more serious medical condition and should be evaluated by a healthcare provider. Additionally, if a fever persists for more than a few days or if it is accompanied by other symptoms such as dehydration, it may require medical attention. It is always a good idea to consult with a healthcare provider if you are concerned about a low-grade fever or any other symptoms you are experiencing.
