Sleep Apnoea Side Effects
Sleep apnoea side effects are numerous and serious.
The first and most obvious symptom of sleep apnoea is when a sufferer wakes choking and / or gasping after an apnoeic event. Another extremely common sleep apnoea symptom is waking tiredness. By rights, a healthy sleeper should wake feeling fully refreshed after their period of deep, restorative sleep. In sleep apnoea patients, the repeated breathing stoppages lead to 'micro arousals', which mean the body wakes sufficiently to start breathing again, but not enough for the sufferer to become aware of waking. As a result, many sleep apnoea sufferers perceive they are getting enough sleep - when, in fact, they are actually getting many short naps. The quality of their sleep is thus disturbed and the true restorative benefits are not enjoyed.
Excessive daytime sleepiness is another common sleep apnoea side effect. In severe cases it is common for sleep apnoea sufferers to fall asleep at the slightest opportunity. This can include while sitting in front of the TV, while sitting at the dinner table, during meetings and, most dangerously, while operating machinery or driving.
Another common side effect of sleep apnoea is nocturia, or frequent nocturnal urination. In a healthy sleeper, most nights should not be interrupted by the need to visit the toilet, whereas in sleep apnoea sufferers it is not uncommon for several trips to the toilet to be needed.
Waking with frontal headaches are an oft-reported side effect of sleep apnoea. These headaches usually pass shortly after waking, but their consistent recurrence is a distinct sleep apnoea side effect.
Hypertension, or consistent high blood pressure, is a common consequence and side effect of sleep apnoea. This is a natural response to the body's constant efforts to breathe while asleep and while the airway is collapsed.
In addition to these side effects of sleep apnoea, there are numerous risk indicators which should also be looked for.
People who are obese or have a high Body Mass Index are at a significantly higher risk of having sleep apnoea. This is primarily because some of the fat deposits are stored in the areas of soft tissue of the upper airway, such as the tongue, soft palate, uvula and pharyngeal wall. This leads to a crowded airway and consequent restriction or obstruction of airflow.
People with Type 2 Diabetes are statistically at a higher risk of having sleep apnoea. The exact cause of this is not know, although a growing body of research suggests that obesity, type 2 diabetes and hypertension is are, in fact, side effects of sleep apnoea.
As a very rough guideline, a person who snores and suffers from any of the other listed conditions is very likely to have sleep apnoea. A person who is obese, hypertensive and type 2 diabetic is almost certainly suffering from a significant form of sleep apnoea.
The only sure way to determine if a person has sleep apnoea is to undergo a diagnostic sleep study. If you wish to conduct a self-assessment prior to undergoing a diagnostic sleep study, try using our free self assessment tool.
