Asthma signs and symptoms

 Asthma is a common chronic inflammatory disease of the pathway that is characterized by variable and recurrent symptoms, reversible respiratory obstruction and bronchospasm. Common symptoms include wheezing, cough, chest tightness, and respiratory problems.

Asthma is thought to be a combination of genetic and environmental factors. The diagnosis is usually based on the pattern of symptoms, response to treatment over time, and spirometry. It is clinically classified based on frequency of symptoms, forced expiratory volume (FEV1) and peak expiratory flow rate in one second. The disease is also classified as atopic (external) or non-atopic (inner) where Atopy has been referred to as pre-adapted to the development of type 1 hypersensitivity reactions.

Severe symptoms are usually treated with an inhaled short-acting beta-2 agonist (such as salbutamol) and oral corticosteroids. Intravenous corticosteroids, magnesium sulfate, and hospitalization may be necessary in each severe case. Symptoms can be prevented by protecting against allergens and irritants such as catalysts and by the use of corticosteroids. Corticosteroids inhaled to long-term active obstructive beta (LABA) or leukotriene antagonists may be used if asthma symptoms remain uncontrolled. The symptoms of asthma have increased significantly since the 1970s. As of 2011, 235–300 million people worldwide were affected, including approximately 2,50,000 deaths.

Signs and symptoms

Asthma is characterized by frequent wheezing, shortness of breath, chest tightness, and cough. Cough may arise from the lungs due to cough but it is very difficult to bring it out. When recovering from a seizure, it may look like pus that is caused by high levels of white blood cells called snowflakes, usually at night and early in the morning or because of the reaction to exercise and cold air. Some people with asthma usually experience symptoms rarely in response to catalysts, while others show and persist.

Related conditions

Many other health conditions occur more frequently in people with asthma, including: gastro-esophageal reflex disease (GERD), rhinosinusitis, and obstructive sleep apnea. Psychological disorders are also quite common, of which anxiety disorder occurs in 16–52% of people and mood disorder in 14–41% of people. However, it is not yet known whether asthma causes psychological problems or psychological problems are the cause of asthma.

reason

Asthma is caused by a combination of complex and insufficiently understood environmental and gene interactions. These factors affect its severity and response to treatment. It is believed that the recent increase in asthma rate is due to changing epigenetic (paternal factors other than those related to DNA sequence) and the changing environment.

Environmental

Many environmental factors have been associated with the development and spread of asthma, including allergens, air pollution, and other environmental chemicals. Smoking during pregnancy and subsequent smoking is associated with a severe risk of asthma-like symptoms. Low air quality or high ozone levels due to traffic pollution are associated with the development of asthma and its increased severity. Volatile organic compounds indoors can be catalysts for asthma; For example, formaldehyde exposure has a positive relationship. Also, the pethfallets present in PVC are related to asthma in children and adults, and so is the endotoxin exposure.

Asthma is related to exposure with allergens present indoors. Common household allergens include dust mites, cockroaches, animal dandruff and mold. Efforts to reduce dust mites have been found to be ineffective. Certain types of virus-induced respiratory infections may increase the risk of developing asthma, especially when acquired in childhood as respiratory syncytial virus and rhinovirus. However some other types of infections may reduce the risk.

Hygiene hypothesis

The hygiene hypothesis is a theory that attempts to explain the increased rate of asthma worldwide as a direct and unintentional consequence of decreased exposure during childhood to non-infectious bacteria and viruses. The assumption is that the reason for the decrease in exposure to bacteria and viruses is, in part, the increased hygiene and reduced family size in modern societies. Evidence supporting the hygiene hypothesis includes reduced asthma rates in domestic and farm animals.

Antibiotic use in early life is associated with the development of asthma. Also, caesarean birth is related to an increased risk of asthma (about 20 to 80%) - this increased risk is due to the lack of a swarm of healthy bacteria that the newborn will ingest via the placenta. There is a correlation between the rate of prosperity.

Genetic

Family history is a risk factor for asthma in which various genes have been included. If one of the identical twins is affected then the other is likely to be affected.
