Frequent yawning can have various causes, ranging in severity from 'minor' to 'critical'. 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 frequent yawning, we could:
history of birth control pill use
heart attack(s) in father
high uric acid level
rapid pulse rate
major unexplained weight loss
shortness of breath when at rest
hiccups
long-term low-carb dieting
reduced sense of smell
long-term hypertension
heaviness of the legs

| Heart Disease | 90% | Confirm |
| Schizophrenia | 57% | Possible |

Roughly how often do you yawn, on average?
Possible responses:
→ Never / a few times per year perhaps→ I'd say less than average → Average / a few times per day / don't know → Many times during the day → Several times every hour |
Excessive yawning can be caused by a vasovagal reaction and may indicate a heart problem.
It has been observed that schizophrenic patients tend not to yawn often and, conversely, that persons who yawn a lot tend not to have schizophrenia.
