What is the Cause of Recurring Fever?

What Causes Recurring Fever?

Recurring fever can have various causes, ranging in severity from 'needs attention' to 'generally fatal'. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.

Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose recurring fever, we could:

Research the topic
Find a doctor with the time
Use a diagnostic computer system.

The process is the same, whichever method is used.

Step 1: List all Possible Causes

We begin by identifying the disease conditions which have "recurring fever" as a symptom. Here are eight of many possibilities (more below):

Hepatitis
Valley Fever (Coccidioidomycosis)
Diverticular Disease
Lyme Disease
Kidney Stones
Ehrlichiosis
AML Leukemia
Gallbladder Disease

Step 2: Build a Symptom Checklist

We then identify all possible symptoms and risk factors of each possible cause, and check the ones that apply:

highly elevated lymphocyte count

non-human estrogen use

significant abdominal distension

very great unexplained weight loss

frequent unexplained nausea

migraine headaches

moderate right hypochondriac pain

insufficient water consumption

high cigarette smoke sensitivity

frequent 'chills'

very weak urine stream

Lyme disease

... and more than 100 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of recurring fever:

Cause	Probability	Status
Hepatitis	91%	Confirm
Diverticular Disease	27%	Unlikely
Kidney Stones	23%	Unlikely
AML Leukemia	2%	Ruled out
Valley Fever (Coccidioidomycosis)	2%	Ruled out
Lyme Disease	1%	Ruled out
Gallbladder Disease	1%	Ruled out
Ehrlichiosis	1%	Ruled out

* This is a simple example to illustrate the process

Arriving at a Correct Diagnosis

The Analyst™ is our online diagnosis tool that learns all about you through a straightforward process of multi-level questioning, providing diagnosis at the end.

In the Metabolic Symptoms section of the questionnaire, The Analyst™ will ask the following question about severity of unexplained recurring fevers:

If you suffer from unexplained recurring fever, how would you rate its average severity?

Possible responses:

→ Not applicable / don't know
→ Very mild, almost nothing
→ Mild - I can function normally with it
→ High - I can function but I would rather be in bed
→ Very high - I'm bedridden

Based on your response to this question, which may indicate mild unexplained fevers, moderate unexplained fevers, unexplained high fevers or unexplained fevers that hit hard, The Analyst™ will consider possibilities such as:

Acute Myelogenous Leukemia (AML)

Babesiosis

Dermatomyositis

Diverticular Disease

Ehrlichiosis

Gallbladder Disease

Hepatitis

Kidney Stones (Urolithiasis)

Lupus, SLE (Systemic Lupus Erythematosus)

Fever of more than 100F (38C) is reported by 90% of lupus patients.

Lyme Disease

Valley Fever (Coccidioidomycosis)
