Asthma

Symptoms

• coughing, especially at night, when laughing, or during exercise
• wheezing or whistling sound made when breathing
• tightness in the chest
• shortness of breath
• fatigue

Doctors might avoid using the terms “totalis” and “universalis” because some people may experience something between the two. It’s possible to lose all hair on the arms, legs and scalp, but not the chest, for example.

Cause of Asthma

No single cause has been identified for asthma. Instead, researchers believe that the breathing condition is caused by a variety of factors. These factors include:

• Genetics. If a parent has asthma, you’re more likely to develop it.
• History of viral infections. People with a history of viral infections during childhood are more likely to develop the condition.
• Early allergen exposure. Frequent contact with possible allergens and irritants may increase your risk for developing asthma.

Asthma triggers

Certain conditions and environments may also trigger symptoms of asthma. These triggers include:

• Illness. Respiratory illnesses such as the flu and pneumonia can trigger asthma attacks.
• Exercise. Increased movement may make breathing more difficult.
• Irritants in the air. People with asthma may be sensitive to irritants such as chemical fumes, strong odors, and smoke.
• Allergens. Animal dander, dust mites, and pollen are just a few examples of allergens that can trigger symptoms.
• Extreme weather conditions. Conditions such as very high humidity or low temperatures may trigger asthma.
• Emotions. Shouting, laughing, and crying may trigger an attack.

Treatment of Asthma

Treatments for asthma fall into three primary categories:

• breathing exercises.
• rescue or first aid treatments, and.
• long-term asthma control medications.
