Asthma is a disease affecting the airways that carry air to and from your lungs. People who suffer from this chronic condition (long-lasting or recurrent) are said to be asthmatic.

The inside walls of an asthmatic’s airways are swollen or inflamed. This swelling or inflammation makes the airways extremely sensitive to irritations and increases your susceptibility to an allergic reaction. As inflammation causes the airways to become narrower, less air can pass through them, both to and from the lungs. Symptoms of the narrowing include wheezing (a hissing sound while breathing), chest tightness, breathing problems, and coughing. Asthmatics usually experience these symptoms most frequently during the night and the early morning.

According to recent estimates, asthma affects 300 million people in the world. Although people of all ages suffer from the disease, it most often starts in childhood. Asthma kills about 255,000 people worldwide every year.

Children at Risk
Asthma is the most common chronic disease among children – especially children who have low birth weight, are exposed to tobacco smoke, are black, and are raised in a low-income environment. Most children first present symptoms around 5 years of age, generally beginning as frequent episodes of wheezing with respiratory infections. Additional risk factors for children include having allergies, the allergic skin condition eczema, or parents with asthma.

Young boys are more likely to develop asthma than young girls, but this trend reverses during adulthood. Researchers hypothesize that this is due to the smaller size of a young male’s airway compared to a young female’s airway, leading to a higher risk of wheezing after a viral infection.

Allergies
Almost all asthma sufferers have allergies. In fact, over 25% of people who have hay fever (allergic rhinitis) also develop asthma. Allergic reactions triggered by antibodies in the blood often lead to the airway inflammation that is associated with asthma.
Common sources of indoor allergens include animal proteins (mostly cat and dog allergens), dust mites, cockroaches, and fungi. It is possible that the push towards energy-efficient homes has increased exposure to these causes of asthma.

Tobacco Smoke
Tobacco smoke has been linked to a higher risk of asthma as well as a higher risk of death due to asthma, wheezing, and respiratory infections. In addition, children of mothers who smoke – and other people exposed to secondhand smoke – have a higher risk of asthma prevalence. Adolescent smoking has also been associated with increases in asthma risk.

Environmental Factors
Allergic reactions and asthma symptoms are often the result of indoor air pollution from mold or noxious fumes from household cleaners and paints. Other indoor environmental factors associated with asthma include nitrogen oxide from gas stoves. In fact, people who cook with gas are more likely to have symptoms such as wheezing, breathlessness, asthma attacks, and hay fever.
Pollution, sulfur dioxide, nitrogen oxide, ozone, cold temperatures, and high humidity have all been shown to trigger asthma in some individuals.

During periods of heavy air pollution, there tend to be increases in 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 airways.

Weather changes have also been known to stimulate asthma attacks. Cold air can lead to airway congestion, bronchoconstriction (airways constriction), secretions, and decreased mucociliary clearance (another type of airway inefficiency). In some populations, humidity causes breathing difficulties as well.

Obesity
Overweight adults – those with a body mass index (BMI) between 25 and 30 – are 38% more likely to have asthma compared to adults who are not overweight. Obese adults – those with a BMI of 30 or greater – have twice the risk of asthma. According to some researchers, the risk may be greater for nonallergic asthma than allergic asthma.

Pregnancy
The way you enter the world seems to impact your susceptibility to asthma. Babies born by Caesarean sections have a 20% increase in asthma prevalence compared to babies born by vaginal birth. It is possible that immune system-modifying infections from bacterial exposure during Cesarean sections are responsible for this difference.
When mothers smoke during pregnancy, their children have lower pulmonary function. This may pose additional asthma risks. Research has also shown that premature birth is a risk factor for developing asthma.

Stress
People who undergo stress have higher asthma rates. Part of this may be explained by increases in asthma-related behaviors such as smoking that are encouraged by stress. However, recent research has suggested that the immune system is modified by stress as well.

Airway Hyperreactivity
Researchers are not sure why airway hyperreactivity is another risk factor for asthma, but allergens or cold air may trigger hyperreactive airways to become inflamed. Some people do not develop asthma from airway hyperreactivity, but hyperreactivity still appears to increase the risk of asthma.

Atopy
Atopy – such as eczema (atopic dermatitis), allergic rhinitis (hay fever), allergic conjunctivitis (an eye condition) – is a general class of allergic hypersensitivity that affects different parts of the body that do not come in contact with allergens. Atopy is a risk factor for developing asthma.

Some 40% to 50% of children with atopic dermatitis also develop asthma, and it is probable that children with atopic dermatitis have more severe and persistent asthma as adults.

Asthma is Incurable
Asthma is an incurable illness. However, with good treatment and management using swissgarde herbal supplements there is no reason why a person with asthma cannot live a normal and active life.

What is an Asthma Episode/Attack?
An asthma episode, or an asthma attack, is when symptoms are worse than usual. They can come on suddenly and can be mild, moderate or severe.

What happens during an asthma attack?
The muscles around your airways tighten up, narrowing the airway.Less air is able to flow through the airway.Inflammation of the airways increases, further narrowing the airway.More mucus is produced in the airways, undermining the flow of air even more.

Asthma Attacks Vary
In some asthma attacks, the airways are blocked such that oxygen fails to enter the lungs. This also prevents oxygen from entering the bloodstream and traveling to the body’s vital organs. Asthma attacks of this type can be fatal, and the patient may require urgent hospitalization.

Asthma attacks can be mild, moderate, severe and very severe. At onset, an asthma attack does allow enough air to get into the lungs, but it does not let the carbon dioxide leave the lungs at a fast enough rate. Carbon dioxide – poisonous if not expelled – can build up in the lungs during a prolonged attack, lowering the amount of oxygen getting into your bloodstream.

With experience you will learn to keep away from things that irritate your airways, know when to take your medication, and better control your asthma using Swissgarde herbal supplements. Effective asthma control allows you to take part in normal everyday activities.

Menstrual Cycle Affects Asthma Severity
A woman’s respiratory symptoms, including those of asthma, tend to worsen between day 10 to 22 of her menstrual cycle.
Wheezing symptom severity dipped during ovulation (days 14 to 16). Patients with asthma, regular smokers and those with a BMI (body mass index) of more than 23 tend to experience more coughs immediately after ovulation.
