Sleep apnea is a disorder that prevents the body from getting a sufficient amount of oxygen during sleep. During times of sleep, the sleep apnea victim or patient literally stops breathing for small periods of time, creating an extremely dangerous situation. Over 12 million Americans have been diagnosed with sleep apnea and that figure includes women, men, and children though most of victims are older male adults. Sleep apnea is also known as obstructive sleep apnea and it’s the most common form. Throat blockage, mostly from the tongue or palate, is what gives obstructive sleep apnea its name – but it’s only one form. Two other forms are central sleep apnea and mixed sleep apnea.

CAUSES OF SLEEP APNEA

There are several causes, however tongue or palate blockage is the main culprit. Basically, anything that prevents the lungs from getting enough air to the brain is at fault, thus almost all breathing problems have been blamed. From smoking and asthma to being overweight to snoring, sleep apnea is now thought to play a role in developing diabetes, heart attacks, and even death. According to a recent study, 30% of sleep apnea victims dies within four to five years after being diagnosed with one of its most severe forms.

SLEEP APENEA TREATMENT

Most treatments for sleep apnea involve the CPAP machine (continuous positive airway pressure). This machine works to supply the body (lungs and brain) with enough oxygen while the patient is sleeping. Some machines use nasal masks that cover the mouth and nose to send air, while others use a tube-connected mouth or nose piece to deliver air. The idea with either method is to keep the airway open so that a patient gets sufficient air through regular breathing.

Since the CPAP machine is a medical device, it requires a prescription from a neurologist and an polysomnogram (sleep study) examination.

Depending on the severity of the sleep apnea, a CPAP machine may not be needed. Some people have found relieve through natural methods simply by losing weight, cutting out certain foods from a diet, reducing alcohol consumption, or even avoiding certain medications under a doctor’s advice. Others have found help from the intake of specific vitamins and minerals.

Ingesting vitamins and minerals without doctor consent can be dangerous however since a recent report disclosed that taking too many supplements (or the wrong ones) can cause problems rather than relieve them. The best supplements to ask a doctor about are the ones that stimulate circulation, reduce cholesterol, regulate metabolism.

Herbal remedies should be avoided because they may interfere with medications that a patient may already take. Herbs are a form of medication themselves, and mixing them with prescribed medications without proper knowledge of their effects is extremely dangerous. Under no circumstance, should a patient take a sleeping aid as a way to thwart sleep apnea. Sleeping aids are designed to deepen sleep, while sleep apnea treatments are designed to increase airflow. Both treatments solve completely different problems.

Renal Disease and Hypertension

A patient with hypertension has an increased risk of developing renal disease. In stage I renal disease, the patient has a diminished renal reserve but no symptoms of renal disease. If untreated, the condition may progress to stage II renal disease, in which the patient experiences renal insufficiency. He’ll have lost over 75% of his glomerular function and will begin to experience the effects of renal disease, such as anemia and mild hyperkalemia. Further uncontrolled hypertension can lead to stage III, end-stage renal disease, in which the patient may develop chronic renal failure. How it occur

In hypertension, increased vascular resistance of the sclerosed vessels causes blood to enter the glomerulus under high pressure, damaging the glomerular membrane. The impaired membrane loses its ability to filter selectively, leading to necrosis of the tubules.

Hypertension also interferes with the renin­angiotensin-aldosterone system, resulting in ischemia and reduced blood volume to the kidneys. Water and sodium reabsorption are increased in an attempt to increase the glomerular filtration rate, resulting in volume overload and higher vascular pressure, which cause sclerosis of the glomeruli.

Noninvasive tests for peripheral vascular disease include segmental pressure measurements, anklebrachial indexes, and pulse volume recordings.

For a segmental pressure measurement, blood pressure cuffs are placed at four sites: on the thigh, directly above the knee, directly below the knee, and at the ankle. Then, the pressure cuffs are inflated sequentially. If systolic pressure decreases by 15% or more from one site to another, the patient may have significant lesions.

A physician may order an exercise stress test along with an anklebrachial index and pulse volume recording. During the test, the patient exercises until he develops significant claudication. Then an anklebrachial index is performed by taking systolic blood pressures in the ankle and arm simultaneously. Severe claudication causes a significant difference between the ankle and brachial blood pressures during low-level exercise.

Pulse volume recordings are obtained at the same time as the anklebrachial index. If the patient has significant occlusions, the volume’s amplitude will be reduced, and the height of its contour will be decreased.

Two invasive diagnostic tests, color flow Doppler ultrasonography and angiography, also can detect peripheral vascular disease. These procedures are performed to pinpoint the area of the lesion when surgery or angioplasty is planned. Color flow Doppler ultrasonography allows direct visualization of the major vessels and blood flow. Angiography provides information on the location and extent of the atherosclerotic disease.

A smile can make a major difference to your appearance and change the way people perceive you. A beautiful smile is a big advantage for any individual and it is only natural that we should take all precautions to ensure that our smile remains attractive.

One wearing such braces can easily continue with their social life without people finding out that they are undergoing a dental treatment.

However, even if you opt to wear clear braces you must know that before wearing them you need to wear the metal braces for atleast two weeks. The advantage of the braces are manifolds because you can take them off from time to time without visiting your dentist like for cleaning your teeth and even while eating food. Although some people find this to be a bother if you need to take off the braces time and again. Also, the time taken for rectifying the problem of misaligned teeth is a little longer in case of the transparent braces because they are taken off from time to time.

Clear braces can therefore, solve the dental problem of any individual having misaligned teeth without causing any embarrassment to the patient. All you need to do is find a competent dentist who can provide proper care and guidance and help you in caring for your teeth in the proper manner. It is important to remember that even oral hygiene and care plays an important role in keeping our teeth clean and free from any kind of diseases. Maintain a regular dental care program and visit your dentist regularly to have sparkling, healthy teeth always. It is said that prevention is better than cure and in the case of our teeth this holds very true. In spite of your best intentions if you still face some dental problems then a competent dentist and restorative dentistry procedure can cure you of your tooth and gum ailments easily.
