Overview of Asthma
Asthma is a chronic condition where the airways in the lungs are temporarily inflamed and produces excess mucus. This reduces the volume of oxygen that is carried to the lungs. As a result, the physical activities get hindered, speech becomes difficult, and the person exhibits a characteristic “whistling” sound.
There are many factors that can trigger asthma, these range from allergic substances to viral and bacterial infections. Furthermore, people with asthma have extremely sensitive airways, so minuscule irritants such as pollen, animal dander (which are similar to dandruff in humans) can cause the airways to be inflamed. Even cold, dry weather potentially triggers asthma to flare up.
Asthma symptoms and the frequency of flare-ups (asthma attacks) vary from person to person. Sometimes, a combination of several factors, such as running in cold weather can promptly trigger the onset of asthma.
Characteristic symptoms of asthma include:
- Difficulty in breathing
- A characteristic whistling sound
- Coughs, which gets worse at night
- Trouble falling asleep due to problems in breathing
- Fatigue and tiredness
Precautionary measures prevent asthma flare-ups, these include tracking and avoiding potential triggers, taking long-term preventive medicines etc. In case of a flare-up, quick-relief inhalers can ease the condition right away.
