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.

When should parents be concerned about their child vomiting? If the child, age 5 and a bit overweight, has what the parents think is a stomach bug that causes vomiting, and this happens for a couple days at least every two months or sometimes shorter periods in between, should they have tests done or should they just assume its a virus?

Diarrhea can occur in cancer patients for a number of reasons. The tumor itself can bring on this side effect, as can changes in diet or an infection in the intestine. The most common cause of diarrhea in cancer patients, however, is cancer treatment. Chemotherapy, radiation, and surgery can all cause diarrhea, and it may arise at any time during treatment.

Detailed information on pain management and itching and burn care Most children with burns have pain. The amount of pain depends on the severity and location of the burn. Severe pain can make your child's stay in the hospital very scary. Your child will be given pain medication through an intravenous (IV) line or by mouth before wound care and as needed. Many parents worry that their child may become addicted to pain medication. This is very rare, because children are given such small amounts of pain medication for short time periods. If you have more questions about pain medication, please ask your child's nurse or physician.

It used to be that having asthma meant choosing between breathing problems and side effects of asthma medicine. But today's asthma treatments have freed people from that choice. You can now breathe easier thanks to highly effective medications with few or no side effects. For people with more than occasional, mild symptoms, today's standard of care calls for consistent, daily use of asthma medications even when you feel well. And with the help of updated asthma guidelines, described in this report, you and your doctor can choose the most effective drugs and dosages to control your asthma while keeping your medication levels as low as possible.

|
|
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.

Detailed information on choking, choking prevention, and the Heimlick maneuver Choking, which is caused by food or another foreign object becoming lodged in the throat, or airway, accounts for nearly 4,300 deaths each year. Choking prevents oxygen from getting to the lungs and the brain. Lack of oxygen to the brain for more than four minutes may result in brain damage or death. It is important for all persons to recognize and know how to handle choking both in the home and in restaurants and other public places. The Heimlich maneuver, an emergency procedure used to treat choking victims, is responsible for saving thousands of lives each year.

|
If a person who is choking is still able to speak, their airway does not have a significant obstruction, so the Heimlich maneuver should not be performed.
