Respiratory Problems, Age 11 and Younger
Topic Overview
Most babies and older children have several mild infections of the
Reference respiratory system Opens New Window Reference
Opens New Window each year.
Upper respiratory system
The upper respiratory system includes the nose, mouth, sinuses, and throat. A child with an upper respiratory infection may feel uncomfortable and sound very congested. Other symptoms of an upper respiratory infection include:
- A Reference runny or stuffy nose. This may lead to blockage of the nasal passages, causing the child to breathe through his or her mouth.
- Irritability, restlessness, poor appetite, and decreased activity level.
- Coughing, especially when lying down.
- Fever that occurs suddenly and may reach 105°F (41°C).
Lower respiratory system
The lower respiratory system includes the bronchial tubes and lungs. Respiratory problems are less common in the lower respiratory system than in the upper respiratory system.
Symptoms of a lower respiratory (bronchial tubes and lungs) problem usually are more severe than symptoms of an upper respiratory (mouth, nose, sinuses, and throat) problem. A child with a lower respiratory problem is more likely to require a visit to a doctor than a child with an upper respiratory problem.
Symptoms of lower respiratory system infections include:
- Shallow coughing, which continues throughout the day and night.
- Fever, which may be high with some lower respiratory system infections, such as pneumonia.
- Irritability, restlessness, poor appetite, and decreased activity level.
-
Reference Difficulty breathing Opens New Window. You may notice:
- Reference Rapid breathing.
- Grunting, which is heard during the breathing out (exhaling) phase of breathing. Most babies grunt occasionally when they sleep. But grunting that occurs with rapid, shallow breathing may mean lower respiratory system infection.
- Reference Wheezing Opens New Window (which is a different sound than Reference croup Opens New Window).
- Flaring the nostrils and using the neck, chest, and abdominal muscles to breathe, causing a "sucking in" between or under the ribs (Reference retractions).
Respiratory problems may have many causes.
Viral infections
Viral infections cause most upper respiratory infections. Sore throats, colds, croup, and Reference influenza (flu) Opens New Window are common viral illnesses in babies and older children. These infections are usually mild and go away in 4 to 10 days, but they can sometimes be severe. For more information, see the topics Reference Croup and Reference Influenza (Seasonal Flu).
Home treatment can help relieve the child's symptoms. The infection usually improves on its own within a week and is gone within 14 days.
Antibiotics are not used to treat viral illnesses and do not alter the course of viral infections. Unnecessary use of an antibiotic exposes your child to the risks of an Reference allergic reaction Opens New Window and antibiotic side effects, such as nausea, vomiting, diarrhea, rashes, and yeast infections. Antibiotics also may kill beneficial bacteria and encourage the development of dangerous Reference antibiotic-resistant Opens New Window bacteria.
Viral lower respiratory system infections may be mild, similar to upper respiratory system infections. An example of a possibly serious viral infection is Reference bronchiolitis Opens New Window. Up to 10% of babies and children with viral infections of the lower respiratory system, such as those caused by Reference respiratory syncytial virus Opens New Window (RSV), may develop severe blockage of the air passages and require hospitalization for treatment. For more information, see the topics Reference Acute Bronchitis, Reference Pneumonia, and Reference Respiratory Syncytial Virus (RSV) Infection.
Bacterial infections
The most common sites for bacterial infections in the upper respiratory system are the sinuses and throat. A Reference sinus infection Opens New Window is an example of an upper respiratory bacterial infection.
Bacterial Reference pneumonia may follow a viral illness as a Reference secondary infection Opens New Window or appear as the first sign of a lower respiratory infection. In babies and small children, the first sign of infection often is rapid breathing, irritability, decreased activity, and poor feeding. Antibiotics are effective against bacterial infections.
Reference Tuberculosis Opens New Window is a less common bacterial infection of the lower respiratory system.
Allergies
Allergies are a common cause of respiratory problems. Allergy symptoms in children include:
- Clear, runny drainage from the nose or a stuffy nose. Children often rub their noses by pushing the tip upward with the palm of the hand ("allergic salute").
- Sneezing and watery eyes. Often there are dark circles under the eyes ("allergic shiners").
- Irritability and loss of appetite.
Asthma
Babies and small children usually do not have Reference asthma Opens New Window. But the number of new cases of asthma increases with age.
- In babies and small children, a hacking cough may be the only symptom of mild asthma.
- If asthma worsens, symptoms may include wheezing and shortness of breath after exercise or at nighttime.
- In severe asthma, difficulty breathing (using the neck, chest, and abdominal muscles to breathe) and a high-pitched sound when breathing (wheezing) are the most common symptoms.
- Allergies and asthma often occur together. For more information, see the topic Reference Asthma in Children.
Other causes
Besides asthma, allergies, and infection, other possible causes of respiratory problems in children include:
- Exposure to cigarette smoke. Tobacco smoke impairs lung growth and development. Children who are exposed to tobacco smoke, even before birth (prenatal), are more likely to have asthma and other respiratory problems.
- Blockage of the airway by an Reference inhaled object, such as food, a piece of a balloon, or a small toy. For more information, see the topic Reference Swallowed or Inhaled Objects.
- Problems that have been present from birth (genetic causes), such as Reference cystic fibrosis Opens New Window.
Babies and children younger than age 3 may have more symptoms with respiratory problems than older children, and they may become more ill. For this reason, younger children need to be watched more closely. The type and severity of the symptoms helps determine whether your child needs to see a doctor.
Reference Check your child's symptoms to decide if and when your child should see a doctor.
