ASTHMA ; Causes And Control.

ASTHMA;
Asthma is a major noncommunicable disease (NCD), affecting both children and adults, and is the most common chronic disease among children.

It is a long-term condition affecting children and adults. The air passages in the lungs become narrow due to inflammation and tightening of the muscles around the small airways.
This causes symptoms such as cough, wheeze, shortness of breath and chest tightness. These symptoms are intermittent and are often worse at night or during exercise.

ASTHMA TIGGERS 

Other common triggers can make asthma symptoms worse. Triggers vary from person to person, but can include viral infections (colds), dust, smoke, fumes, changes in the weather, grass and tree pollen, animal fur and feathers, strong soaps and perfume.

Common signs and symptoms include:

• Shortness of breath
• Cough
• Chest tightness or pain
• Wheeze (a whistling sound when you breathe)
• Waking at night due to the symptoms
• A drop in your peak flow meter reading (if you use one)

Not everyone with this has the same symptoms. You may only have one symptom, or you may have many symptoms.

CAUSES OF ASTHMA.

• Family history
  If you have a parent with asthma, you are three to six times more likely to develop asthma than someone who does not have a parent with it.
• Allergies
  Some people are more likely to develop allergies than others, especially if one of their parents has allergies.
  Certain allergic conditions, such as atopic dermatitis (eczema) or allergic rhinitis (hay fever), are linked to people who get this.
• Viral respiratory infections
  Respiratory problems during infancy and childhood can cause wheezing. Some children who experience viral respiratory infections go on to develop this.
• Occupational exposures
  If you have asthma, exposures to certain elements in the workplace And, for some people, exposure to certain dusts (industrial or wood dusts), chemical fumes and vapors.

Smoking
Cigarette smoke irritates the airways. Smokers have a high risk of asthma. Those whose mothers smoked during pregnancy or who were exposed to secondhand smoke are also more likely to have it.
