Coughing is an important way to keep your throat and airways clear. However, excessive coughing may mean you have an underlying disease or disorder.Some coughs are dry, while others are considered productive.
|
|
Coughs, those mini-explosions in your throat, are valuable weapons in your body's self-defense arsenal. Their assignment: keep airways clear by quickly expelling intruders from the lower respiratory system -- principally your throat and upper lungs. If dust, fluid, viruses, bacteria or even tumors block any part of this region, your cough reflex takes explosive action.
|
|
Your doctor should evaluate you if you are having symptoms that suggest a more serious cause, such as a bacterial infection, or if your symptoms aren't manageable with over-the-counter remedies or the passing of time.

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.
