Snoring Problems
Body Weight and Sleep Apnea

There is a clear association of increased body weight to obstructive sleep apnea. Excess body weight is linked with many serious health conditions, including high blood pressure, heart disease, stroke, diabetes, and cancer.  Additionally, it has recently been found that mid-life obesity may contribute to memory problems late in life.  Untreated sleep apnea may worsen obesity-related conditions such as high blood pressure and diabetes.  As little as a 10% drop in body weight can reduce the severity of snoring and sleep apnea in some patients.  Obstructive sleep apnea that is moderate or severe is less likely to be fully cured by typical weight loss efforts.  In such cases, continuous positive airway pressure (CPAP) therapy is the best treatment.  However, losing a few pounds or at least avoiding increases in body weight can prevent worsening of sleep apnea while offering other health benefits.  For patients on CPAP therapy who lose or gain significant weight, reassessment of your CPAP settings by your sleep medicine doctor may be needed.
 

A standard practice in monitoring weight is to calculate the body mass index (BMI), which takes into account both height and weight. See left to connect to the link or go to http://rs6.net/tn.jsp?et=1102598974499&s=730&e=001RtpXIifRWtEz1ABNAZe75eDr98-VALPyKFh8WSSEcwWpqao9AEvIuW8BcSERnRzhMx_UzsT4c7J29cV5zSk-w2pNESxG4S-_GYjql4PrVetIDa3l6P0lMcPCV8dUa2cj8t9EjDywCyQ=.
If your BMI is 30 or more, your health may be at increased risk from body weight issues.  The BMI is a reasonable measure of your body weight status and can be useful in tracking changes over time, but the BMI does not factor in individual differences.   For example, a body builder may have an elevated BMI due to increased muscle, but would not be at risk for weight-related health problems.  For many health conditions, including diabetes and sleep apnea, waist circumference is likely a more sensitive measure to assess the risks.  Men with a waist of more than 40 inches and women with a waist greater than 35 inches are at increased risk for health problems due to body weight. 

Bruxism

Grinding or clenching of teeth in sleep, often quite loud and alarming to a bed partner, is called bruxism.  Chronic bruxism may result in tooth pain and damage, but also may contribute to discomfort and popping with movement of the jaw at the TemporoMandibular Joint (TMJ).  Morning headaches may result.  Should you grind your teeth in sleep, see your dentist about the need for a protective mouthpiece.  
 
Dr. Heath Roberts, DDS  hroberts@sleepmed.com is also available in our Dallas office for assessment and treatment of sleep bruxism.  Bruxism is thought to be made worse by stress and anxiety, but is also linked with other sleep disorders such as sleep apnea.  If bruxism is interfering with your sleep, evaluation by a sleep specialist could be of benefit.

Rate Your Daytime Sleepiness

When you come into our office, we often ask you to complete a rating of daytime sleepiness.  The simplest scale to use is the Epworth Sleepiness Scale (ESS).  Anything that reduces good sleep will cause you to feel sleepier during the day.  Sometimes medications will increase your sleepiness.  A change in your sleep disorder can also increase sleepiness.  If you have an Epworth sleepiness score of 11 or above, your doctor will want to explore reasons for the sleepiness.  This link on our website will take you to the ESS Click Here to Rate Your Daytime Sleepiness.  If your ESS rating is 11 or above, it may be time for you to visit your doctor. 
Sincerely,
