    The Pill versus The Device

    March 27th, 2012 by DrLowrance | ShareThis

    What if you could take a pill that relieves all the symptoms of erectile dysfuncdtion, diabetes, high blood pressure, obesity, memory problems and more?  Sounds great? Would you buy the pills even if they didn’t treat the “cause”?

    A company listed on the stock exchange has such a pill in clinical testing.

    Now let me offer you another option.  What if you could purchase a “device” that treats the cause of erectile dysfunction, diabetes, high blood pressure, obesity, memory problems and more?  You get the benefit of treating the symptoms and with the bonus of treating the cause without taking expensive pills with side effects.

    Is treating the Symptoms as wise a choice as treating the Cause?

    What is this miracle device?  It is a removable Oral Appliance that is comfortable, effective and much easier to sleep with than a CPAP.  No hoses, no humidifiers, no masks, no straps, no noise, no need for an electrical outlet and definitely not “butt ugly”.

    The FDA (Food and Drug Administration) has approved over 50 different oral appliances to treat Sleep Apnea whick is the cause or aggravating factor in all the diseases I have listed.  SomnoMed Flex, Herbst, SAUD, TAPIII and many others have already been clinically tested and in use for several years treat Sleep Apnea and its symptoms.

    If you wear a CPAP and want to know how to switch to an Oral Device or if you have one or more of the symptoms listed above, contact my office at (210) 294-5111.  I can help you.

    Can Tonsils in Childen increase Heart Disease Risks

    March 27th, 2012 by DrLowrance | ShareThis

    A new study just published in the Dec. issue of Otolaryngology Journal (the journal for ENT specialist) suggest that there is enough evidence to warrant concern and more research in this area.  It is well established that children with Sleep Apnea have an increased risk for heart disease.  What this research paper described is the possible relationship between enlarged tonsils and adneoids and the reduced levels of two particular blood markers that are associated with heart disease and inflammation.

    Sleep Disordered Breathing, as a result of enlarged tonsils and adenoids, is a common indication for removal of tonsils and adenoids.  The participants in the study were between the ages of 3 and 13 and all had enlarged tonsils and adenoids and had obstructive sleep apnea due to the large tonsils and adenoids.  Blood markers for CRP and ET-1 (a protein know to increase blood pressure) were measured before and after.

    The study concluded that there were indeed improvement in the quality of life of the children and reduction in the heart disease associated blood markers.  The research suggest that more studies with larger patient pools need to be done to firmly establish this link.

    In the mean time, children with enlarged tonsils need to be screen for removal of the tonsils and adenoids if breathing and physical thriving are affected by them.  The secondary benefit may be reduced incidence of cardiovascular disease as they age.

    Don’t Blame the Mattress! Bad Sleep May Be Due to Sleep Apnea

    February 3rd, 2012 by blogger | ShareThis

    Ideally, sleep should be relaxing and refreshing, allowing the body to rejuvenate itself. While we sleep, the body continues working, as hormone levels are rebalanced. We all hope for sleep that lasts for hours and allows us to wake up feeling ready for the day ahead; however, if you’re anything like a good portion of the rest of society, you probably don’t always get that perfect sleep you aim for. We’ve all had days where we wake up still feeling tire. In efforts to improve sleep quality, some will take sleeping pills; others will focus on relaxation techniques to ease the mind; and still others will choose to replace their mattresses. While some of these efforts may be successful for some; others find that they still fall short of a good night’s sleep.

    Consider The Factors

    Before any patient can truly experience and enjoy quality sleep, it’s important to understand that sleeping problems aren’t always caused by just one single issue. Some patients may sleep poorly due to their sleeping position, while others may wake up tired on a daily basis because of an underlying and untreated sleep disorder, such as sleep apnea. There are plenty of factors that can interrupt the sleep cycle and pinpointing the problem is a patient-by-patient requirement.

    If you toss and turn at night and find that your nights are more restless than restful, it never hurts to change things up, such as your mattress or your nightly routine to see if any change is experienced; however, it’s important to remember that such changes will not help a patient with an undiagnosed sleep disorder. Sleep apnea can only be treated with effective sleep apnea treatment.

    Don’t let tired days and restless nights keep you from living a happy life. If you suffer from the common symptoms of sleep apnea, now is the time to undergo a physician-run sleep study for proper diagnosis. If you are diagnosed with sleep apnea, consult with Dr. Lowrance to learn more about sleep apnea treatment and what method is most suitable for you.

    Diagnosis By Computers?

    January 25th, 2012 by blogger | ShareThis

    Star Trek fan or not, you probably have heard or known something about Dr. McCoy’s tricorder, which he often used to determine the medical and chemical components of mysterious objects. Such a device fit the futuristic theme and setting of the show; but who would have imagined that, years later, a medical device similar to the tricorder is in the works and may one day be used in the medical and dental world. Though it seems a bit far-fetched, today’s advanced technology has made a tricorder-like device possible.

    In fact, the X Prize-Foundation is hosting a competition, with the award of $10 million, for inventors to create, a medical device that is designed and programmed to be able to successfully diagnose 15 different medical conditions in just 3 days. The diagnosis of each medical condition must be done without the intervention or assistance of a health care professional, such as a doctor, nurse, or dentist. The contest is said to begin sometime in 2012; and though competition rules aren’t explicitly listed just yet, the X Prize-Foundation’s senior director has mentioned that the device will need to be able to diagnose sleep apnea, hypertension, and other medical conditions.

    Technology Has It’s Downfalls

    While the benefits of such devices and the advancements behind them are nothing short of amazing, these instruments may do more harm than good. Diagnoses devices put much more power and choice into patients’ hands, while at the same time leaving patients clueless as to what’s next. Not all patients will know what to do once they are diagnosed with a certain condition. Some may never follow up with a medical professional at all, which could put the patient’s health and life at risk. A diagnosis is only the first step towards properly dealing with a dangerous medical condition, such as sleep apnea. When patients are diagnosed with serious health problems, they need advice, help, and information from a healthcare professional.

    Sleep apnea is usually diagnosed through a sleep physician-provided sleep study. During this time, a diagnosis is given and further information, such as treatment options, is often provided. A device similar to the tricorder wouldn’t be able to provide such information.

    Though modern technology continues to spread into all facets of society, modern devices shouldn’t be seen as a way to replace the traditional health-care professional. Instead, technology should be used alongside a medical professional to make diagnosis as quick and accurate as possible.

    If you suspect that you may be suffering from sleep apnea, don’t hesitate to schedule an appointment with Dr. Lowrance. He can refer you to a sleep center to undergo a sleep study. If you receive a positive diagnosis, Dr. Lowrance will work with you to provide the information you need regarding sleep apnea treatment. To get started, call or email our office today.

    Sleep Apnea a Real Problem in the Bedroom

    January 18th, 2012 by blogger | ShareThis

    More than an average of 12 million Americans suffer from sleep apnea. These same 12 million-plus are at risk of suffering from a variety of health problems, including heart disease, obesity, diabetes, insomnia, and many more. Recent studies have found that – not only does sleep apnea negatively impact the cardiovascular system along with sleeping schedules – it also reduces the libido in both men and women, usually due to a lack of sleep or a lack of quality sleep.

    Both men and women who have untreated sleep apnea are at a higher risk of suffering from sexual dysfunction. In men, erectile dysfunction (ED) is often caused or worsened by constantly disrupted sleep. In fact, a 2009 German study found that, out of all of the tested male subjects, 70 percent who suffered from sleep apnea also suffered from ED.

    Problems In The Bedroom Are Treatable

    How can interrupted breathing and an obstructed airway lead to sexual dysfunction? While sleep apnea is commonly linked to daytime sleepiness and loud snoring, the consequences of the condition go far beyond these two problems. Sleep apnea can cause sexual dysfunction, such as ED, because during periods of non-breathing, the blood oxygen levels deplete. When the amount of oxygen within the blood decreases, it throws off hormone production and balance, which then negatively impacts sexual activity and function.

    In men, sleep apnea can cause ED and other bedroom problems due to the fact that the male hormone, testosterone, is created and regulated during sleep. When sleep is inconsistent and of poor quality, the body isn’t able to properly produce or regulate testosterone, which then leads to low testosterone levels.

    To prevent or undo this potential problem, a reliable sleep apnea treatment is your best course of action. For help choosing a suitable sleep apnea treatment that’s just right for you, contact Dr. Lowrance’s office by phone or through email to schedule an appointment. With the right treatment plan, you’ll feel better, sleep better; and your night life will most definitely improve.
