Drowsiness can have various causes, ranging in severity from 'troubling' to 'serious'. 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 drowsiness, we could:
|Lack Of Sleep||21%||Unlikely|
|Progesterone Excess||4%||Ruled out|
|Metal Toxicity||0%||Ruled out|
General drowsiness. Roughly how often do you find yourself falling asleep in situations such as boring meetings, watching TV or while driving? Do not include drowsiness that occurs 1-3 hours after eating a meal.
Possible responses:→ Never / rarely / only after a meal / don't know
→ Once a month or less
→ Once a week or less
→ A few times per week
→ At least daily
Some patients suffering from OSA fall asleep in a nonstimulating environment, such as while reading something uninteresting or in a quiet room. Others may fall asleep in a stimulating environment, such as during business meetings, while eating, and even while having sex.
So-called "drowsy driver syndrome", which some believe is responsible for many automobile accidents, may result from OSA. Drivers may fall asleep at the wheel or suffer from a lack of alertness because of sleep deprivation. Decreased alertness places the person at risk in a variety of potentially hazardous situations.
