Unexplained Daytime Sweating

What Causes Unexplained Sweating During The Day?

Unexplained sweating during the day can have various causes, ranging in severity from 'minor' to 'life-threatening'.  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 unexplained sweating during the day, 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 "unexplained sweating during the day" as a symptom.  Here are eight of many possibilities (more below):
  • Stress
  • High Histamine
  • Low Estrogens
  • Lymphatic Congestion
  • Chronic Fatigue-Fibromyalgia
  • Guillain-Barre Syndrome
  • Kidney Disease
  • Hyperthyroidism

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:
lighter/paler skin color
poor muscular strength
bulging eyes
low lymphocyte count
facial burning/tingling
an average-stress lifestyle
phobias
hyperthyroidism in family members
irritated eyes
severely tight muscles
high systolic blood pressure
very tender muscles
... and more than 160 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of unexplained sweating during the day:
Cause Probability Status
Chronic Fatigue-Fibromyalgia 98% Confirm
Hyperthyroidism 24% Unlikely
Stress 22% Unlikely
Guillain-Barre Syndrome 1% Ruled out
Low Estrogens 0% Ruled out
Kidney Disease 0% Ruled out
Lymphatic Congestion 0% Ruled out
High Histamine 0% 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 unexplained daytime sweating:
Do you experience inappropriate/excessive sweating during the day? Only include sweating that is not explained by a hot/humid climate, physical exertion, or dressing too warmly.

→ Never / rarely / less than once a year
→ Yes, I sweat excessively several times a year
→ Yes, regular/frequent unexplained sweating
→ Yes, regular/frequent unexplained heavy sweating
Based on your response to this question, which may indicate no unexplained daytime sweating, some unexplained daytime sweating, unexplained daytime sweating or heavy unexplained daytime sweating, The Analyst™ will consider possibilities such as:
