A significant portion of people with obstructive sleep apnea (OSA) have been found to have underlying nutritional deficiencies, sometimes linked to the severity of the condition. Understanding **what deficiency causes apnea** symptoms to worsen is a critical step towards developing a more holistic management plan. While diet alone is not a cure, it can be a vital component of supporting overall sleep health.

A 2019 case study documented a patient whose severe vitamin B12 deficiency led to excessive daytime sleepiness, a common symptom of sleep apnea, which resolved with supplementation. This raises the critical question: **Can B12 deficiency cause apnea?** While typically not a direct cause, the deficiency can significantly impact sleep through its effects on the nervous system and circadian rhythms.
