A fever is a natural immune response, with your body's thermostat resetting to a higher temperature to fight off invaders. However, when a fever appears to strike without reason, leaving you feeling unwell one moment and fine the next, it can be puzzling and concerning. This is especially true for those asking, 'Why does fever come randomly?'

According to the University of Rochester Medical Center, fevers due to illness typically last three to four days, but a fever that is on and off, or intermittent, may indicate a more persistent issue. Understanding the difference between a normal illness-related fever and a recurring one is crucial for proper management and knowing when to seek medical attention.

Did you know that a person's body temperature can naturally fluctuate throughout the day? However, when your temperature repeatedly climbs back up, the question of **why is my fever rising again** is a valid concern that warrants investigation to properly address the root cause.

While most fevers resolve quickly, an intermittent fever—one that comes and goes—is a signal that your body is actively battling an underlying issue. A variety of conditions can cause this pattern, from common infections to more complex health issues, making it important to understand what is the most common cause of intermittent fever.

Approximately 75% of fevers are caused by viral infections, but when a fever comes and goes, it can be a sign of something more persistent or complex than a common cold. Understanding **what causes a fever to come on and off** is crucial for identifying potential underlying health issues and seeking appropriate care.

According to research, a fever is the body's natural response to fight off infection, but when it returns repeatedly, it signals an underlying health issue. If you're wondering, **What causes a recurring fever?** the answer can range from persistent infections to complex immune system disorders, and seeking a professional diagnosis is crucial.

Recurring fevers, where a person experiences multiple episodes of fever separated by periods of normal temperature, are medically referred to as periodic fever syndromes or systemic autoinflammatory diseases (SAIDs). These fevers are not caused by typical viral or bacterial infections and can indicate an underlying issue with the immune system.

According to research from AFC Urgent Care, intermittent fevers, those that rise and fall over time, can stem from numerous underlying causes. What does it mean if a fever comes and goes? This pattern is your body's clear signal that it is actively engaged in a recurring battle against an infection, inflammation, or another underlying health issue.

According to medical experts, a fever lasting more than a few days could signal an underlying medical condition, not just a passing bug. Understanding **what could be the reason for persistent fever** is a critical first step toward seeking the right diagnosis and treatment from a healthcare professional.
