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
  • Dehydration
  • Salt Need
  • Hypoglycemia
  • Adrenal Fatigue
  • PMS C
  • Chronic Fatigue-Fibromyalgia
  • Mitral Valve Prolapse

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:
severe fatigue after slight exertion
vision disturbances
tongue swelling
being a "night person"
rotten egg burps
occasional confusion/disorientation
history of postpartum depression
poor mental clarity
severe hallucinations
much lower back pain
numb/burning/tingling extremities
cold sores
... and more than 170 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
PMS C 95% Confirm
Salt Need 13% Unlikely
Chronic Fatigue-Fibromyalgia 23% Unlikely
Adrenal Fatigue 1% Ruled out
Mitral Valve Prolapse 0% Ruled out
Hypoglycemia 0% Ruled out
Stress 0% Ruled out
Dehydration 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.
