When this increased sensitivity causes a reaction, the muscles that control the airways tighten. In doing so, they might restrict the airways even further and trigger an overproduction of mucus. The set of inflammatory events in the respiratory system can lead to the severe symptoms of an asthma attack. Worldwide, around , people die every year as a result of asthma. Asthma attacks occur when symptoms are at their peak. They might begin suddenly and can range from mild to severe. In some asthma attacks, swelling in the airways can completely prevent oxygen from reaching the lungs, which also stops it entering the bloodstream and traveling to vital organs.
At the start of an asthma attack, the airways allow enough air into the lungs, but it does not let the carbon dioxide leave the lungs at a fast enough rate. Carbon dioxide is poisonous if the body does not expel the gas, and a prolonged asthma attack might lead to a build-up of the gas in the lungs. People with clear symptoms of asthma should visit a doctor. They will provide treatments and advise on management techniques, as well as identifying potential triggers for asthma symptoms and how to avoid them.
The doctor will also prescribe medications to help reduce the frequency of attacks asthma. As many different factors come together to cause asthma, there are many different types of the disease, separated by age and severity. Adults and children share the same triggers for symptoms that set off an allergic response in the airways, including airborne pollutants, mold, mildew, and cigarette smoke. Children are more likely to have an intermittent form of asthma that presents in severe attacks.
Some children might experience daily symptoms, but the common characteristic among children with asthma is a heightened sensitivity to substances that cause allergy. Second-hand tobacco smoke causes severe problems for children with asthma.

Between , and 1 million children experience worsening asthma symptoms as a result of second-hand smoke, according to the American Lung Association. The Centers for Disease Control and Prevention CDC advise that children experience more emergency visits and admissions for asthma than adults. Mild asthma might resolve without treatment during childhood.
However, there is still a risk that the condition might return later on, especially if symptoms are moderate or severe. Asthma in adults is often persistent and requires the daily management of flare-ups and preventing symptoms. Asthma can begin at any age. Allergies lead to at least 30 percent of adult presentations of asthma. Obesity is a strong risk factor for adult-onset asthma, and women are more likely to develop the condition after the age of 20 years. People over 65 years of age make up a large number of deaths from asthma.
Symptoms will become apparent after attending a particular workplace.
Industries with regular associations to occupational asthma include baking, laboratory work, or manufacturing. In this type, the work environment leads to the return of childhood asthma or the start of adult-onset asthma. These types involve consistent, debilitating asthma symptoms and breathing difficulties. Around 12 percent of people with asthma have difficult-to-control or severe asthma. With the correct medication and effective trigger avoidance, those in this category can bring asthma symptoms back under control.
Roughly 5 percent of people with asthma do not see improvements after using the standard asthma medications. These people have severe asthma, and there are several types of severe asthma depending on the cause. Newer medications are becoming available to address the different forms of severe asthma, such as eosinophilic asthma that does not link to any allergic reactions.https://wordhokabiwa.ga
This type occurs in response to allergens that are only in the surrounding environment at certain times of year, such as cold air in the winter or pollen during hay fever season. Many different aspects of a person's environment and genetic makeup can contribute to the development of asthma. Asthma is the most common chronic disease among children. The first symptoms become clear at around 5 years of age in the form of wheezing and regular infections in the respiratory tracts.
One study in the Annals of Asthma, Allergy, and Immunology suggests that over 65 percent of adults with asthma over the age of 55 years also have an allergy, and the figure is closer to 75 percent for adults between the ages of 20 and 40 years. Common sources of indoor allergens include animal proteins, mostly from cat and dog dander, dust mites, cockroaches, and fungi.
Research has linked tobacco smoke to an increased risk of asthma , wheezing, respiratory infections, and death from asthma. In addition, the children of parents who smoke have a higher risk of developing asthma.

Smoking makes the effects of asthma on the airways worse by adding coughing and breathlessness to its symptoms, as well as increasing the risk of infections from the overproduction of mucus. Allergic reactions and asthma symptoms often occur because of indoor air pollution from mold or noxious fumes from household cleaners and paints. Heavy air pollution tends to cause a higher recurrence of asthma symptoms and hospital admissions.
Smoggy conditions release the destructive ingredient known as ozone, causing coughing, shortness of breath, and even chest pain. These same conditions emit sulfur dioxide, which also results in asthma attacks by constricting the airways. Changes in the weather might also stimulate attacks.
Cold air can lead to airway congestion, constricted airway, extra secretions of mucus, and a reduced ability to clear that mucus. Some studies, such as this report from , suggest a link between obesity and asthma, although the American Academy of Asthma, Allergies, and Immunology does not recognize obesity as a formal risk factor for asthma. However, the report in question suggests that the inflammatory mechanisms that drive asthma also link to obesity.
