Most adults and older children have several respiratory infections each year. Respiratory problems can be as minor as the common cold or as serious as pneumonia. They may affect the upper respiratory system (nose, mouth, sinuses, and throat) or the lower bronchial tubes and lungs.
The upper respiratory system includes the nose, mouth, sinuses, and throat. When you have an upper respiratory infection, you may feel uncomfortable, have a stuffy nose, and sound very congested. Other symptoms include:
The lower respiratory system includes the bronchial tubes and lungs. These types of problems are less common than ones in the upper respiratory system. But their symptoms are usually more severe.
Respiratory problems may have many causes.
Viral infections are the most common cause of upper respiratory symptoms. Symptoms often come on quickly (over hours to a day or two) without prior illness. Common viral illnesses include colds and influenza (flu).
Antibiotics aren't used to treat viral illnesses. They don't change the course of viral infections. Using an antibiotic when you don't need one exposes you to the risks of an allergic reaction and antibiotic side effects. These side effects include nausea, vomiting, diarrhea, rashes, and yeast infections. Antibiotics also may kill helpful bacteria and encourage the growth of dangerous antibiotic-resistant bacteria.
Bacterial infections may develop after a viral illness, such as a cold or influenza. They are less common than viral illnesses. They may affect the upper or lower respiratory system. Symptoms tend to be in one area. In the upper respiratory system, the most common sites of bacterial infections are the sinuses and throat. In the lower respiratory system, the most common site is the lungs (pneumonia).
Bacterial infections are more common in people who smoke, are exposed to secondhand smoke, or have chronic lung disease (such as asthma or chronic obstructive pulmonary disease [COPD]) and other chronic medical problems. Antibiotics work well to treat most bacterial infections.
Allergies, especially hay fever, are another common respiratory problem. Symptoms include sneezing, clear runny drainage from the nose and eyes, itchy eyes or nose, and stuffy (congested) ears and sinuses. The symptoms of allergies often last longer than a typical viral respiratory infection.
Asthma is a chronic disease of the respiratory system. It causes inflammation and narrowing in the tubes that carry air to the lungs (bronchial tubes). The inflammation leads to wheezing, trouble breathing, tightness in the chest, and a cough.
Asthma often starts during childhood. It may last throughout a person's life. The cause isn't clearly known. Asthma is more common in people who also have allergies.

The plan is designed to help keep your diabetes in control even though you are sick. When you have diabetes, even a minor illness can cause problems.
Temperature varies a little depending on how you measure it. For adults and children age 12 and older, these are the ranges for high, moderate, and mild, according to how you took the temperature.
Oral (by mouth) temperature
A forehead (temporal) scanner is usually 0.5°F (0.3°C) to 1°F (0.6°C) lower than an oral temperature.
Armpit (axillary) temperature
Symptoms of a severe allergic reaction (anaphylaxis) may include:
A severe reaction can be life-threatening. If you have had a bad allergic reaction to a substance before and are exposed to it again, treat any symptoms as an emergency. Even if the symptoms are mild at first, they may quickly become very severe.
Symptoms of a heart attack may include:
For men and women, the most common symptom is chest pain or pressure. But women are somewhat more likely than men to have other symptoms, like shortness of breath, nausea, and back or jaw pain.

Based on your answers, you may need care soon. The problem probably will not get better without medical care.

Based on your answers, you may need care right away. The problem is likely to get worse without medical care.

Call 911 or other emergency services now.
Sometimes people don't want to call 911. They may think that their symptoms aren't serious or that they can just get someone else to drive them. Or they might be concerned about the cost. But based on your answers, the safest and quickest way for you to get the care you need is to call 911 for medical transport to the hospital.
After you call 911, the operator may tell you to chew 1 adult-strength (325 mg) or 2 to 4 low-dose (81 mg) aspirin. Wait for an ambulance. Do not try to drive yourself.
Here are some things you can do at home to help you feel more comfortable when you have mild to moderate respiratory symptoms.
Let your symptoms be your guide. If you have a cold, you may be able to stick to your usual routine and just get some extra sleep.
Let yourself cough if you have a cough that brings up mucus from the lungs. Coughing can help prevent bacterial infections. People who have chronic bronchitis or emphysema need to cough to help clear mucus from their lungs.
Try a vaporizer or humidifier to add moisture to the room. Warm or cool mist may help relieve symptoms. Follow all cleaning instructions and precautions for the machine.
Here are some precautions to take when using decongestants.
Call a doctor if any of the following occur during self-care at home:
