Although nausea and vomiting can make you feel miserable, it's important to remember that these are not diseases, but rather symptoms of many illnesses.
|

Vomiting is very common in babies. Sometimes it can be entirely normal, like when babies spit up mouthfuls of breastmilk or formula after eating. Sometimes it can be a sign of illness or a blockage somewhere in the intestines. Less commonly, it can even be a sign of accidental poisoning or be caused by a bad bump to the head.

Dyspnea is the technical word for difficulty breathing. It's a common symptom in people who have lung cancer or have cancer that has spread to the lungs. People who experience dyspnea describe it as difficulty in breathing or shortness of breath. They often compare it to feeling like they are suffocating or being smothered. In many cases, patients may develop anxiety or panic if they feel they cannot breathe. Often their anxiety and fears can make the dyspnea worse. By panicking, patients can become more breathless and begin a cycle that is hard to stop.

Detailed information on the most common breathing problems in a newborn Babies breathe much faster than older children and adults. A newborn's normal breathing rate is about 40 times each minute. This may slow to 20 to 40 times per minute when the baby is sleeping. The pattern of breathing in a baby may also be different. A baby may breathe fast several times, then have a brief rest for less than 10 seconds, than breathe again. This is often called periodic breathing and is a normal occurrence. Babies normally use their diaphragm (the large muscle below the lungs) for breathing.
|
|
Severe shortness of breath and shortness of breath accompanied by certain symptoms requires immediate medical attention.
|
|
If your child cannot seem to get enough breath in his lungs (shortness of breath) or is having a hard time breathing, he probably has a medical condition that needs treatment. If your child is old enough to talk, he can tell you that he is having difficulty breathing. If your child is younger, you may notice that he is breathing harder or faster than usual, isn't feeding well, or is cranky.

For the past two months I have experienced increased shortness of breath. I have chronic asthma, but there's concern the shortness of breath could be caused by a blockage in heart.

Detailed information on hearing loss in babies According to the National Institutes of Health (NIH), nearly 12,000 babies are born each year in the United States with a hearing impairment. It is estimated that serious hearing loss occurs in about one to three of every 1,000 healthy newborns, and in two to four of every 100 babies in newborn intensive care units. Without screening or testing, hearing loss may not be noticed until the baby is more than 1 year old. If hearing loss is not detected until later years, there will not be stimulation of the brain's hearing centers. This can affect the maturation and development of hearing, and can delay speech and language. Social and emotional development and success in school may also be affected.
|
|
As you age, some hearing loss is normal. You lose more than the ability to hear how loud a sound is. You also lose the ability to hear certain types of sounds. For example, you might not be able to hear some of the high-pitched sounds of a child's voice.

People who are tone deaf, or amusic, are unable to distinguish differences in pitch, and may have a similar difficulty with rhythm. Research suggests this may be due to weak connections between the parts of the brain responsible for processing music.

Detailed information on noise-induced hearing loss When the ears are exposed to extremely loud noises, or to prolonged loud noises, inner ear structures can be damaged, leading to noise-induced hearing loss. Noise-induced hearing loss is quite common, affecting about one-third of the nearly 30 million Americans who suffer from hearing loss.
