Snoring is a condition where something in the nose, mouth, throat or lungs blocks breathing while sleeping producing a soft or loud and unpleasant sound. It is a sign or first alarm of OSA (obstructive sleep apnoea).
Sleep Apnoea is where there are one or more pauses in breathing while you sleep. Pauses may last a few seconds to minutes, and as many as 30 times an hour. Breathing usually restarts with a loud snort or choking sound. Sleep apnoea may be obstructive, central or a combination called complex sleep apnoea.
Snoring and Obstructive sleep apnoea- In the nose a crooked nose bone or polyps are common causes, in the throat, throat muscle weakness, loose or tight jaw, fat in the neck, thick tongue, loose low roof of mouth, or tongue falling back while sleeping on the back. Relaxants like alcohol or some medicines also cause this.
Signs and symptoms-
Risk factors- overweight, male, over 50, smoker, high blood pressure, alcoholic, or thick neck collar size over 40 cm. Crooked nose bones, large tonsils, flat chin, allergies and nasal polyps.
Medical- all treatments for snoring and sleep apnoea try to fix the blockage or bypass it. These include special pillows, devices to keep the jaw aligned or the nose open, machines that continuously blow air into the nose and throat to keep them open (CPAP). These are all for mild to moderate cases.
Surgical- Uvulopalatopharyngoplasty (removal of tissues in back of throat), surgery to correct crooked nose bones and remove extra tissues from the nose, removal of tonsils , reducing the size of the tongue, and insertion of stiff materials into the top of the mouth . Hyoid advancement where the bone in the neck to which tongue is attached is pulled up and forward, tongue advancement by moving the tip of the jaw outward, lower jaw advancement, where the entire upper and lower jaw is moved forward by 1.2 cm, and making a hole in the neck called a permanent tracheostomy (for extreme cases).

Sleeping on the side (or ask bed partner to roll you over if you snore), wedge a pillow stuffed with tennis back behind the back to prevent rolling onto the back, elevate the head of the bed by 4 to 6 inches.
