Most medical professionals agree a fever by itself is not an illness; it is a symptom of an underlying problem. Fevers actually can be a positive sign the body is fighting an infection. However, a fever can cause discomfort for a child.
|
|
A fever is a way for the body to fight infection. But it may also be a sign of a serious illness, especially in children younger than 3 months and children who haven't been immunized. Know when to seek medical care for your child.

Detailed information on fever, including when to call your physician Fever (also called pyrexia) is defined as body temperature that is higher than normal for each individual.

The best way to take an infant's temperature is rectally with a digital thermometer (never use a glass mercury thermometer). Taking the temperature under the arm, or using an ear thermometer, is less exact.
|
|
Use a digital thermometer to take your child's temperature; never use a glass mercury thermometer. Most children aged three years and older can hold a thermometer under their tongue. If your child is younger than that, or you're having difficulty with the oral method, talk to your doctor about the best way to take his temperature.

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.
|
|
A cough is a forceful release of air from the lungs that can be heard. Coughing protects the respiratory system by clearing it of irritants and secretions.While people can generally cough voluntarily, a cough is usually a reflex triggered when an ...

Chest pain is discomfort or pain that you feel anywhere along the front of your body between your neck and upper abdomen.Many people with chest pain fear a heart attack. However, there are many possible causes of chest pain.
|
|
New onset chest pain always requires evaluation by your doctor. If the pain is severe, you should seek immediate medical care.
|
|
If hospitals become accredited as "chest pain centers," it could make deciding where to go for treatment easier, and also increase recovery rates.
|
|
Doctor-patient communication can improve the treatment outlook for those with chronic chest pain.

Every now and then I get a sudden, sharp pain on the left side of my chest, like a knife. I get a little dizzy, and then it disappears as quickly as it came on. Even though the test results were fine, it still scares me. Should I be concerned about this?

The benefits of chest pain regarding acute coronary events.When it comes to exercise, that old chestnut "No pain, no gain” is passé. But it may still apply to heart attacks. People who have chest pain (angina) with activity in the months or weeks before a heart attack tend to have smaller heart attacks, better survival, fewer heart rhythm problems, and better recovery of heart function than those without chest pain. In May, a team that included cardiologists from Harvard-affiliated Brigham and Women's Hospital reported in the Journal of the American College of Cardiology that angina protects against the muscular remodeling of the left ventricle that can follow a heart attack and lead to heart failure. It didn't seem to help people with diabetes, though.

Shortness of breath, or dyspnea, is a feeling of difficult or labored breathing that is out of proportion to the patient''s level of physical activity. It is a symptom of a variety of different diseases or disorders and may be either acute or chron...
|
|
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.

Shortness of breath may be a warning sign of heart disease.
Chest pain is a near-universal signal of heart disease. Shortness of breath may be an equally valuable tip-off.

I had a quadruple bypass seven years ago. A few months back I found myself taking frequent short breaths when I climbed the stairs. Once I stopped exerting myself, my breathing soon returned to normal. Is this due to a problem with my heart or lungs?
|
|
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. I have experienced difficulties in the past when anesthetized. Is there an effective alternative to heart catheterization? I've read about a new CT scan ? is it recommended?

Loss of appetite is a loss of the desire to eat. Not eating can lead to weight loss. Weight loss can cause weakness and fatigue, which affect your ability to perform normal activities. Proper nutrition also helps your body prevent and fight infection. Weight loss or lack of appetite may be due to the cancer or sometimes to treatments for the cancer.

Your loss of appetite may be because of anxiety or depression, aging, medications or a health concern.
