Fever Patterns: What Your Body's Temperature Tells Us
The pattern of your fever is a diagnostic clue that most doctors overlook. We analyze timing, duration, and cycles to identify what standard testing misses.
If you've been experiencing recurring fevers without clear diagnosis, the specific pattern of your fever may hold the answer.
Understanding Fever Patterns
Fever patterns refer to the characteristic temperature curves observed over time in patients with elevated body temperature. Different underlying causes produce distinct fever patterns: intermittent fever (peaks daily with return to normal), remittent fever (elevated without returning to normal), sustained fever (constantly elevated), relapsing fever (episodic with pain-free intervals), and hectic fever (wide swings typical of septic conditions).
Common Misconception
A fever is just a fever—regardless of when or how it occurs.
Medical Reality
Different pathogens and disease processes produce characteristic fever patterns. Malaria produces tertian or quartan patterns based on species; TB often shows evening spikes; lymphoma causes cyclic fever; autoimmune diseases may show relapsing patterns.
Root Cause Matrix
Specific fever patterns are associated with particular underlying conditions.
Malaria (Plasmodium species)
Parasite erythrocytic cycle causes fever spikes every 48-72 hours

Mycobacterial infection typically causes evening/night spikes with drenching sweats

Cyclic fever (Pel-Ebstein) every 1-2 weeks; cytokine production by tumor cells
Learn moreAdult-Onset Still's Disease
Daily spike fever with evanescent rash; high ferritin
