There are several key factors that increase a persons risk of developing obstructive sleep apnea.
Sex- The risk of developing obstructive sleep apnoea is notable greater in men or people born male. The risk for females and those female at birth is highest in the post menopausal stage of life.
Age- Age is a consistent and rising factor.
BMI- Body Mass Index is based measured on a persons height and age. The likelihood of developing obstructive sleep apnoea rises with your BMI
Family history of obstructive sleep apnea.
Alcohol consumption
Pre-existing medical conditions-  TMJ, TMD, Hyperthyroidism, Asthma, Diabetes and Hypertension are all associated with increased risk of obstructive sleep apnoea.
Enlarged tonsils- particularly prevalent in children suffering with obstructive sleep apnoea .
Facial configurations – a large neck circumference or small lower jaw.
The management of obstructive sleep apnoea once diagnosed by a team of the appropriate  medical practitioners is largely dependent on the factors that contributed to that diagnosis.
