Bronchial asthma is a medical condition which causes the airway path of the lungs to swell and narrow.

Bronchial Asthma

Asthma is an inflammatory disease of the airways to the lungs. It makes breathing difficult and can make some physical activities challenging or even impossible. Normally, with every breath you take, air goes through your nose or mouth and down into your throat and into your airways, eventually making it to your lungs.

There are lots of small air passages in your lungs that help deliver oxygen from the air into your bloodstream. Asthma symptoms occur when the lining of your airways swell and the muscles around them tighten. Mucus then fills the airways, further reducing the amount of air that can pass through.

The most common symptom of asthma is wheezing, a squealing or whistling sound made when you breathe. Not everyone with asthma will experience these particular symptoms. There are many different types of asthma. The most common type is bronchial asthma, which affects the bronchi in the lungs.

Additional forms of asthma include childhood asthma and adult-onset asthma. Irritants in the air not related to allergies trigger this type of asthma. These irritants might include:. Exercise-induced bronchoconstriction EIB usually affects people within a few minutes of starting exercise and up to 10—15 minutes after physical activity.

Up to 90 percent of people with asthma also experience EIB, but not everyone with EIB will have other types of asthma. About 9 percent of people with asthma have AIA.

It usually develops suddenly in adults between the ages of 20 and Instead, your doctor will use a variety of criteria to determine if the symptoms are the result of asthma. Instead, they may prescribe asthma medications to your child and wait to see if symptoms improve. If they do, your child likely has asthma. For adults, your doctor may prescribe a bronchodilator or other asthma medication if test results indicate asthma. If symptoms improve with the use of this medication, your doctor will continue to treat your condition as 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:. These exercises can help you get more air into and out of your lungs.

Over time, this may help increase lung capacity and cut down on severe asthma symptoms. Your doctor or an occupational therapist can help you learn these breathing exercises for asthma. These medications should only be used in the event of asthma symptoms or an attack. They provide quick relief to help you breathe again. Bronchodilators work within minutes to relax the tightened muscles around your airwaves.

They can be taken as an inhaler rescue or nebulizer. If you think that someone you know is having an asthma attack, tell them to sit them upright and assist them in using their rescue inhaler or nebulizer. Two to six puffs of medication should help ease their symptoms. If you frequently need to use quick-relief medications, you should ask your doctor about another type of medication for long-term asthma control.

This treatment uses an electrode to heat the airwaves inside the lungs, helping to reduce the size of the muscle and prevent it from tightening. It becomes increasingly difficult to breathe because your airways are swollen and your bronchial tubes have narrowed. Although an exacerbation can end quickly without medication, you should contact your doctor because it can be life threatening. The longer an exacerbation continues, the more it can affect your ability to breathe.

They result in similar symptoms, including wheezing, coughing, and trouble breathing. However, the two conditions are quite different. COPD is an umbrella term used to identify a group of progressive respiratory diseases that include chronic bronchitis and emphysema. These diseases cause reduced airflow due to inflammation in the airways.

The conditions may worsen over time. Asthma can occur at any age, with a majority of diagnoses coming in childhood. Most people with COPD are at least age 45 at the time of their diagnosis. Over 40 percent of people with COPD also have asthma, and the risk for having both conditions increases with age. These triggers can make breathing problems worse.

The most common cause of COPD is smoking. In fact, smoking accounts for up to 9 out of 10 COPD-related deaths. The goal of treatment for both asthma and COPD is to reduce symptoms so you can maintain an active lifestyle. Certain conditions and environments may also trigger symptoms of asthma. The list of possible causes and triggers is extensive. Triggers include:. Your doctor can help you put an asthma action plan in place so that you know which treatments to use and when.

In addition to using maintenance medications, you can take steps each day to help make yourself healthier and reduce your risk for asthma attacks. These include:. Nutrient-rich foods are vital to helping reduce symptoms, but food allergies can trigger asthma symptoms. However, there are many effective treatments that can decrease asthma symptoms.

Lifestyle changes and medications can also help improve your quality of life. You can connect to a physician in your area using the Healthline FindCare tool. The more you know, the more proactive you can be in improving your lung function and how you feel.

Last updated on Sep 8, In fact, roughly This equates to about 7. An asthma attack is exactly that - the muscles around the airways and the lining of the air passages quickly tighten and restrict breathing. The exact reason why people get asthma is not fully known. A family history and the environment seem to play a role for most but not all people. In sensitive people, breathing in allergy-causing substances called "allergens" or "triggers" can start the onset of asthma symptoms.

Asthma is a long-term inflammatory disease of the airways of the lungs. Asthma is thought to be caused by a combination of genetic and environmental factors. There is no cure for asthma. However, its easily treatable.

Asthma is an inflammatory disease of the airways to the lungs. It makes breathing difficult and can make some physical activities challenging or even impossible. Normally, with every breath you take, air goes through your nose or mouth and down into your throat and into your airways, eventually making it to your lungs.

Asthma is a chronic disease that affects your airways. Your airways are tubes that carry air in and out of your lungs. If you have asthma, the inside walls of your airways become sore and swollen. That makes them very sensitive, and they may react strongly to things that you are allergic to or find irritating. When your airways react, they get narrower and your lungs get less air.

 Премного благодарен, приятель! - крикнул тот ему вслед.  - Увидишь Меган, передавай от меня привет! - Но Беккер уже исчез. Двуцветный вздохнул и поплелся к танцующим.
