Dangerous Disease Asthma


What is Asthma: Asthma is a chronic disease that affects your airways. Simply airways are the tubes to carry air in and out of your lungs. In asthma these airways are swelling. These swelled airways get narrower, and less air flows through to your lung tissue. This causes symptoms like wheezing (a whistling sound when you breathe), coughing, chest tightness, and trouble breathing, especially at night and in the early morning.

Asthma Attack:

In asthma attack, muscles around the airways tighten up, making the airways narrower so less air flows through. Mucus also narrows the airways. These changes make it harder to breathe. Asthma attacks are not all the same—some are worse than others. In some attacks the airways can close so much that not enough oxygen gets to vital organs. In this condition people can die from severe asthma attacks.

Symptoms of Asthma:

Common asthma symptoms include:

  • Coughing: Coughing from asthma is often worse at night or early in the morning, making it hard to sleep.
  • Shortness of breath: Some people say they can't catch their breath, or they feel breathless or out of breath. You may feel like you can't get enough air in or out of your lungs.
  • Faster breathing: Faster breathing or noisy breathing.
  • Wheezing: Wheezing is a whistling or squeaky sound when you breathe.
  • Chest tightness: This can feel like something is squeezing or sitting on your chest.

Some time asthma symptoms change according to person’s health and body structures. Sometimes symptoms can be mildly annoying, other times they can be serious enough to make you stop what you are doing, and sometimes symptoms can be so serious that they are life threatening.

Symptoms also differ in how often they occur. Some people with asthma have symptoms only once every few months, others have symptoms every week, and still other people have symptoms every day. With proper treatment, however, most people with asthma can expect to have few or no symptoms.
