The most frequent symptom of sleep apnea is tiredness during the day. Other symptoms may include: dry mouth in the mornings, excessive perspiration, frequent urination at night, memory loss, headaches, exhaustion, nightmares, sexual dysfunction, irritability, aggression, loss of concentration, depression.
Sleep apnoea can cause not only a drop in quality of life but also a shorter life expectancy due to secondary diseases. If untreated the condition can cause cardiac disrhythmia, cardiac insufficiency, seizure (stroke), cardiac arrest, apoplectic seizure (stroke), cardiac arrest, and psychological problems. Medical studies have shown that 50% – 70% of people with sleep apnoea suffer from high blood pressure, compared to only 10% – 20% of the population at large. Unfortunately sleep apnoea is not usually identified as a cause of these symptoms and so they are treated but not solved.
