Sleep apnea is a condition in which airflow is temporarily interrupted for more than 10 seconds due to airway obstruction or damage to the central nervous system. In addition to daytime sleepiness and fatigue upon waking, this condition also has many silent symptoms.

Poor concentration: Sleep apnea affects a person's ability to think clearly during the day. Adequate sleep helps the brain recover, reorganize information, consolidate memories, regulate emotions, and maintain cognitive function. Repeated apnea episodes during the night interrupt sleep, leaving sufferers feeling foggy and unable to concentrate.

Depression: Depression is linked to sleep apnea. Sufferers experience feelings of sadness or dejection, lose interest in previously enjoyed hobbies, and feel guilty about their actions. Low energy and poor concentration can also occur, and some individuals may even have thoughts of self-harm or harming others. Early treatment is crucial to prevent serious consequences.

Uncontrolled high blood pressure: Repeated apnea episodes during sleep lead to decreased blood oxygen levels, sudden increases in heart rate, and elevated blood pressure. If left uncontrolled, this can lead to serious consequences like heart attack and stroke. Treating sleep apnea can help lower high blood pressure.

Frequent nighttime urination (Nocturia): Sleep disorders can disrupt the release of antidiuretic hormone (ADH). This hormone normally prevents frequent nighttime urination. When ADH is not released properly, individuals may need to urinate more often during the night. Nocturia can also stem from drinking too much fluid close to bedtime or using diuretic medications.

Heartburn: Airway collapse during sleep apnea creates pressure in the chest, forcing stomach acid up into the esophagus. This can cause heartburn or acid reflux at night.

Dry mouth: Dry mouth often occurs when nasal passages are blocked, forcing mouth breathing. This can be caused by allergies, a deviated septum, colds, or sleep apnea. Mouth breathing often leads to snoring and contributes to airway narrowing during sleep.

Teeth grinding (Bruxism): Teeth grinding at night can be a sign of sleep apnea. In some people, it occurs unconsciously during sleep to tighten airway muscles and prevent the jaw from being pushed back. Bruxism can damage tooth enamel, cause temporomandibular joint problems, and lead to headaches.
