| Cause | Details |
|---|---|
| Dehydration | Most common cause in young/healthy people - not drinking enough water |
| Medications | Blood pressure drugs, diuretics, antidepressants, alpha-blockers all cause OH |
| Anemia | Low red blood cells = less oxygen to brain on standing |
| Prolonged bed rest / inactivity | Deconditioning weakens the reflex |
| Heat / summer weather | Blood vessels dilate, less reserve |
| Autonomic nervous system issue | Nerves that control BP don't respond fast enough |
| POTS | Heart rate jumps >30 bpm on standing with lightheadedness - more common in young women |
Heart rate increases ≥30 beats/min on standing with symptoms: lightheadedness, palpitations, fatigue, blurred vision, exercise intolerance - without a major blood pressure drop.

Iron deficiency - the most common nutrient deficiency in the world - causes fatigue, dizziness, exertional shortness of breath, pale skin. When you stand, an already oxygen-thin blood supply to the brain drops further.
POTS is defined by a heart rate increase of ≥30 beats/min within 10 minutes of standing, with symptoms of lightheadedness, dizziness, palpitations, fatigue, and blurred vision.
| Most Likely Cause | Fix |
|---|---|
| Dehydration | Drink more water + electrolytes |
| Iron deficiency | Blood test, then iron supplements |
| POTS | Exercise, hydration, salt; doctor if heart races on standing |
| Low baseline BP | Lifestyle adjustments |
| Irregular eating | Regular meals, don't skip breakfast |
