Feeling Dizzy When Standing Up

What Causes Dizziness When Standing Up?

Dizziness when standing up 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 dizziness when standing up, 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 "dizziness when standing up" as a symptom.  Here are eight of many possibilities (more below):
  • Stress
  • Stomach Ulcers
  • Hypotension
  • Chronic Fatigue-Fibromyalgia
  • Mitral Valve Prolapse
  • PMS C
  • Hypoglycemia
  • Adrenal Fatigue

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:
unusual vaginal bleeding
abdominal pain reduced by eating
having trouble concentrating
recently going through divorce
chronic fatigue in family members
heart racing/palpitations
very tender muscles
moderately tight muscles
red palms/fingertips
abnormal taste in mouth
tender muscles
very strong appetite
... 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 dizziness when standing up:
Cause Probability Status
Hypotension 91% Confirm
Adrenal Fatigue 24% Unlikely
Stomach Ulcers 16% Unlikely
Stress 5% Ruled out
PMS C 4% Ruled out
Hypoglycemia 4% Ruled out
Mitral Valve Prolapse 1% Ruled out
Chronic Fatigue-Fibromyalgia 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 General Symptoms section of the questionnaire, The Analyst™ will ask the following question about feeling dizzy when standing up:
Do you ever feel dizzy / faint / lightheaded when standing up or sitting up suddenly?
Possible responses:
→ Don't know
→ Never / very rarely
→ Occasionally - several times per year
→ Often - several times per month
→ Always or almost always
Based on your response to this question, which may indicate either no dizziness when standing up or dizziness when standing up, The Analyst™ will consider possibilities such as:
Gastric/Peptic/Duodenal Ulcers

Patients with a bleeding ulcer may report a sense of passing out upon standing called orthostatic syncope.
