Asthma

Asthma is a Greek word meaning "panting or shortness of breath."

It is a chronic respiratory disease caracterizadapor difficulty breathing due to narrowing of the bronchi and bronchioles is commonly seen in people with allergies. 
Flare-ups often occur in spring and fall or adverse weather conditions and when there are only a few storms and cold air can cause this evil.
It is sometimes caused also by hyperventilation, certain drugs or chemicals, strenuous exercise, hypoglycemia, respiratory infections (bronchitis) , intense and emotional emotions (panic or anxiety , worries and anxieties), the fur of animals (cats , dogs, rabbits, etc..) snuff smoke, dust in the house or commercial food additives ( metabisulfite, monosodium glutamate, sodium caseinate and calcium).
The most common symptoms of asthma are:
  • Rapid pulse, more than 90 beats per minute.
  • Cough and expectoration.
  • Difficulty breathing.
  • Wheezing when exhaling the air and when inhaled.
  • Disnea o Fatiga
Clearly, asthma should be subject to medical monitoring. However, there are some natural remedies for asthma, used in antiquity, and can be used in a complementary way if the doctor deems appropriate.

Children with asthma who live with smokers

  • have asthma attacks more often
  • are more likely to need to go to a medical emergency department following a flare- grave
  • more missing school because of asthma
  • has to take medication to treat asthma more
  • your asthma is more difficult to control, even with medication.
Even children without asthma have more risk of health problems if their parents smoke. These children are more likely to get infections of the upper respiratory tract and developing lung disorders, including asthma. The mere fact that a child is exposed daily to smoke 10 cigarettes increases your risk of developing asthma, even though previously've never had respiratory problems.
And here's the best reason of all for you to quit smoking: the children of parents Smokers are much more likely to smoke when they grow up.
do not have to try to quit on your own. Ask your doctor to indicate possible strategies, from support groups to medication. If you continue to smoke, never do in your home or car.
If your child has asthma, explain to your friends, family and caring for him to snuff the smoke can trigger an asthma attack . Other ways to keep your child breathe in the smoke of other people who smoke snuff include:
  • Do not allow guests to smoke in your home or car.
  • Avoid restaurants and parties where people smoke. Choose non-smoking area is not enough to protect your child.
  • Ask friends and family not to smoke around your child.
  • Choose not to smoke or babysitters, if they smoke, ask them not to smoke with your child.
  • Encourage other family members to stop the snuff.

Classification of Asthma

There are different guidelines for classifying asthma . In this section we classify asthma into the most universal classifications

The extrinsic allergic asthma

There is talk of extrinsic asthma or allergic when symptoms appear as a result of contact between the organism and environmental elements, such as pollen, mites, fungi, etc.., through inhalation, ingestion or skin contact.
In these cases , is the person's immune system which reacts in an exaggerated, as if it were dangerous, to what actually constitutes no real threat. This overreaction causes the production of a large number of antibodies, immune system cells that try to eliminate the foreign substance molecules. These antibodies cause the chain activation of other cells in this system and the release of mediators of inflamciĆ³n, such as histamine, in what is called "inflammatory cascade". These processes are responsible for the mucus in the bronchi are inflamed and smooth muscle to contract, thus hindering the passage of air.
Often asthma is also accompanied by allergic rhinitis and conjunctivitis , which would be the consequence of similar processes previous action of substances such as histamine into the nasal mucosa and conjunctiva.


Intrinsic Asthma

His name is because you can not associate the symptoms with the presence of any external element, or more exactly, immune sensitization to any specific substance.
At times, it has been suggested that this type of asthma appropriate, Actually, those cases where you can not identify the item before which the body reacts .
It is postulated that the origin of this type of asthma is the presence of high or hyper "sensitivity" of the bronchi , so that react a number of different nonspecific stimuli such as strong odors, cold, dry air, excessive moisture, physical exercise, strong emotions, and so on. This excessive bronchial hyperreactivity would result in an excess of sensitivity of nerve receptors in the bronchial mucosa that result from the contraction or spasm of smooth muscle fairly easily.
Through skin reactivity tests (observing the reaction of the skin against contact with a number potential allergens) and bronchial provocation tests (measuring the extent to which declines in lung function after inhaling a bronchoconstrictor substance) can know the type of asthma that presents a person (allergic or intrinsic), and the degree of bronchial hyperreactivity.

Frequently, both types of asthma occur together . Thus, although initially a person can manifest asthma only in the presence of pollen, for example, progressively and as a result of repeated inflammation of the bronchial mucosa, can produce a sensitization of the bronchi to other nonspecific stimuli such as above (cold, dry air, exercise, strong odors, etc.)..
