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.

Diagnose your symptoms now!
  • understand what's happening to your body
  • have a doctor review your case (optional)
  • learn what you should be doing right now

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):
  • Carcinoid Cancer
  • PMS C
  • Hypoglycemia
  • Chronic Fatigue-Fibromyalgia
  • Stress
  • Mitral Valve Prolapse
  • Dehydration
  • Stomach Ulcers

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:
eating during sleep hours
severe upper-right pain after food
slightly tight muscles
much lower back pain
frequent unexplained nausea
reduced mental clarity
recent job/career changes
low diastolic blood pressure
adverse reaction to delayed meals
low energy/stamina
loss of 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
Carcinoid Cancer 92% Confirm
Hypoglycemia 19% Unlikely
Dehydration 14% Unlikely
Mitral Valve Prolapse 0% Ruled out
Chronic Fatigue-Fibromyalgia 0% Ruled out
Stomach Ulcers 0% Ruled out
Stress 0% Ruled out
PMS C 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:
Ectopic Pregnancy

If the ectopic pregnancy has ruptured, profuse bleeding will occur.  This may lead to excess blood loss and symptoms of hypovolemic shock (hemorrhagic shock), including dizziness upon standing.

Gastric/Peptic/Duodenal Ulcers

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