Unexplained Daytime Sweating

What Causes Unexplained Sweating During The Day?

Unexplained sweating during the day can have various causes, ranging in severity from 'worrying' to 'very serious'.  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 six possibilities:
  • Guillain-Barre Syndrome
  • Hyperthyroidism
  • Stress
  • Chronic Fatigue-Fibromyalgia
  • Hypoglycemia
  • Low Estrogens

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:
abnormal taste in mouth
strong-smelling urine
increased emotional instability
poor concentration during cycle
poor recovery from exertion
an average-stress lifestyle
having trouble concentrating
fatigue slightly reduced by eating
poor tolerance of sugars
history of CFS diagnosis
heaviness of the legs
facial burning/tingling
... and more than 140 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
Low Estrogens 92% Confirm
Guillain-Barre Syndrome 58% Possible
Stress 29% Unlikely
Hypoglycemia 3% Ruled out
Chronic Fatigue-Fibromyalgia 2% Ruled out
Hyperthyroidism 0% Ruled out
* This is a simple example to illustrate the process
