Sleep Apnea

Sleep apnea is a common disorder that causes your breathing to stop or get very shallow. Breathing pauses can last from a few seconds to minutes. They may occur 30 times or more an hour.

The most common type is obstructive sleep apnea. It causes your airway to collapse or become blocked during sleep. Normal breathing starts again with a snort or choking sound. People with sleep apnea often snore loudly. However, not everyone who snores has sleep apnea.

You are more at risk for sleep apnea if you are overweight, male, or have a family history or small airways. Children with enlarged tonsils or adenoids may also get it.

Doctors diagnose sleep apnea based on medical and family histories, a physical exam, and sleep study results.

When your sleep is interrupted throughout the night, you can be drowsy during the day. People with sleep apnea are at higher risk for car crashes, work-related accidents, and other medical problems. If you have it, it is important to get treatment. Lifestyle changes, mouthpieces, surgery, and breathing devices can treat sleep apnea in many people.

Smokeless Tobacco

Many people who chew tobacco or dip snuff think it's safer than smoking. But you don't have to smoke tobacco for it to be dangerous. Chewing or dipping carries risks like:

• Cancer of the mouth
• Decay of exposed tooth roots
• Pulling away of the gums from the teeth
• White patches or red sores in the mouth that can turn to cancer

Recent research shows the dangers of smokeless tobacco may go beyond the mouth. It might also play a role in other cancers, heart disease and stroke.

Smokeless tobacco contains more nicotine than cigarettes. Nicotine is a highly addictive drug that makes it hard to stop using tobacco once you start. Having a quit date and a quitting plan can help you stop successfully.

Smoking

What are the health effects of smoking?

There's no way around it; smoking is bad for your health. It harms nearly every organ of the body, even some that you would not expect. Cigarette smoking causes many cancers and other health problems. It is also the cause of nearly one in five deaths in the United States.

Some of the many health problems that smoking can cause include:

• Cancers. Smoking is the most common cause of lung and oral cancers. But it can also cause cancer in many other parts of your body, such as in your larynx (voice box), esophagus, throat, bladder, kidney, liver, stomach, pancreas, colon and rectum, and cervix. It can also cause acute myeloid leukemia (AML).
• Lung diseases. Smoking is the most common cause of COPD. It can also worsen asthma and raise your risk of pneumonia.
• Cardiovascular diseases. Smoking can damage your blood vessels and make them thicken and grow narrower. This makes your heart beat faster and raises your blood pressure. Smoking also increases your risk of blood clots and stroke.
• Vision problems. Smoking can raise your risk of cataracts and cause macular degeneration (AMD).

You have a greater chance of certain pregnancy problems if you smoke while pregnant. Your baby is also at higher risk of dying of sudden infant death syndrome (SIDS).

Smoking also causes addiction to nicotine, a stimulant drug that is in tobacco. Nicotine addiction makes it much harder for people to quit smoking.

Your smoke is also bad for other people. If they breathe in your secondhand smoke, they can get many of the same problems as smokers do. These problems can include heart disease and lung cancer. Children exposed to secondhand smoke have a higher risk of ear infections, colds, pneumonia, bronchitis, and more severe asthma. If you breathe secondhand smoke while pregnant, you're more likely to have preterm labor and a baby with low birth weight.

Besides cigarettes, there are several other forms of tobacco. Some people smoke tobacco in cigars and water pipes (hookahs). These forms of tobacco also contain harmful chemicals and nicotine. Some cigars contain as much tobacco as an entire pack of cigarettes.

E-cigarettes often look like cigarettes, but they work differently. They are battery-operated smoking devices. Using an e-cigarette is called vaping. Researchers still have a lot to learn about the health effects of using e-cigarettes. We do know that they contain nicotine, which is highly addictive and a health danger to you and your fetus if you are pregnant, children, and teens. And e-cigarettes also expose non-smokers to secondhand aerosols (rather than secondhand smoke), which contain harmful chemicals.

Smokeless tobacco, such as chewing tobacco and snuff, is also bad for your health. Smokeless tobacco can cause certain cancers, including oral cancer. It also increases your risk of getting heart disease, gum disease, and oral lesions.

Remember, there is no safe level of tobacco use. Smoking even just one cigarette per day over a lifetime can cause smoking-related cancers and premature death. Quitting smoking can reduce your risk of health problems and add years to your life. The earlier you quit, the greater the benefit. Some immediate benefits of quitting include:

• Lower heart rate and blood pressure
• Less carbon monoxide in the blood (carbon monoxide reduces the blood's ability to carry oxygen)
• Better circulation
• Less coughing and wheezing

Quitting smoking can be challenging, but it is so important for your health. Contact your health care provider if you need help quitting.

Speech and Communication Disorders

Many disorders can affect our ability to speak and communicate. They range from saying sounds incorrectly to being completely unable to speak or understand speech. Causes include:

• Hearing disorders and deafness
• Voice problems, such as dysphonia or those caused by cleft lip or palate
• Speech problems like stuttering
• Developmental disabilities
• Learning disabilities
• Autism spectrum disorder
• Brain injury
• Stroke

Some speech and communication problems may be genetic. Often, no one knows the causes. By first grade, about 5% of children have noticeable speech disorders. Speech and language therapy can help.

Spinal Cord Diseases

Your spinal cord is a bundle of nerves that runs down the middle of your back. It carries signals back and forth between your body and your brain. It is protected by your vertebrae, which are the bone disks that make up your spine. If you have an accident that damages the vertebrae or other parts of the spine, this can also injure the spinal cord. Other spinal cord problems include:

• Tumors
• Infections such as meningitis and polio
• Inflammatory diseases
• Autoimmune diseases
• Degenerative diseases such as amyotrophic lateral sclerosis and spinal muscular atrophy

Symptoms vary but might include pain, numbness, loss of sensation and muscle weakness. These symptoms can occur around the spinal cord, and also in other areas such as your arms and legs. Treatments often include medicines and surgery.
