A low-grade fever is a mild fever, which is usually defined as a temperature of 100.4°F (38°C) or above, but below 102°F (38.9°C). Low-grade fevers are generally considered to be short-lived and are common with colds, flu, and other viral illnesses. They are often accompanied by other symptoms such as body aches, chills, headaches, stuffy nose, and fatigue.
Low-grade fevers are usually not serious and can be treated with home remedies such as drinking plenty of fluids, getting rest, and taking over-the-counter medications such as ibuprofen or acetaminophen for pain and fever relief. In most cases, a low-grade fever will resolve on its own within a few days. However, if the fever persists or is accompanied by severe symptoms, it is important to see a doctor for further evaluation.
In some cases, a low-grade fever may be a sign of a more serious underlying condition such as an infection, autoimmune disorder, or cancer. Therefore, it is important to be aware of any changes in your temperature and to contact your doctor if the fever persists or if other symptoms develop.
