Emphysema is a lung-related chronic respiratory illness. It is characterised by the breakdown of the lungs' alveoli (air sacs), which reduces the surface area available for gas exchange and increases air entrapment. As a result, breathing becomes steadily more difficult, and physical activity capacity declines.
We'll talk about emphysema's definition, causes, types,
stages, symptoms, diagnostic standards, investigation, and treatment in this
blog.
Definition:
Emphysema is a chronic respiratory disease characterized
by the progressive destruction of the walls of the alveoli in the lungs,
leading to a decrease in lung function and an increase in air trapping.
Causes:
Emphysema is primarily brought on by repeated exposure to
irritants, mainly cigarette smoke. Air pollution exposure, passive smoking, and
work-related chemical and dust exposure are other risk factors.
Types:
Emphysema comes in two forms:
The respiratory bronchioles, or tiny airways in the
lungs, are impacted by centriacinar
emphysema. The most frequent association with it is smoking cigarettes.
Emphysema of the panacinar
kind affects the alveoli throughout the lungs uniformly. It frequently occurs
in conjunction with the hereditary disorder known as alpha-1 antitrypsin
deficiency.
Stages:
Depending on how severe the disease is, emphysema has
four stages. These are the stages:
Mild - The patient may have light breathlessness and
infrequent coughing at this stage.
Moderate - During this stage, the patient has more
frequent coughing and shortness of breath, and they may find it challenging to
carry out daily tasks.
Severe - At this stage, the patient has severe exhaustion
and shortness of breath, and supplemental oxygen may be needed.
Very severe - The patient is at a high risk of
respiratory failure at this stage and suffers from severe shortness of breath.
Signs
& Symptoms:
The signs and symptoms of emphysema include:
Shortness of breath, particularly during physical
activity
Wheezing
Chronic cough
Chest tightness
Fatigue
Unintentional weight loss
Bluish lips or fingernail beds (cyanosis)
Diagnostic
Criteria:
Emphysema is diagnosed using a combination of pulmonary
function testing, physical exam, and clinical history. For confirmation of the
diagnosis and to rule out other lung disorders, a chest X-ray or CT scan may be
carried out.
Investigation:
In addition to the diagnostic criteria mentioned above,
other investigations may be necessary to determine the severity of emphysema
and the underlying cause. These investigations may include:
Arterial blood gas test
Alpha-1 antitrypsin deficiency test
Pulmonary function tests
CT scan or MRI of the chest
Electrocardiogram (ECG)
Treatment:
Emphysema does not yet have a cure, however there are
therapies that can help manage the symptoms and decrease the disease's progression.
These remedies could consist of:
Putting an end to smoking and staying away from irritants
Bronchodilators, corticosteroids, and antibiotics are
examples of medications.
Oxygen treatment
Rehabilitation of the lungs
In severe circumstances, surgery
Prevention
of emphysema:
Emphysema prevention generally focuses on preventing
exposure to cigarette smoke, which is the disease's main cause. The following
actions can be taken to prevent emphysema:
1. Give up smoking:
The most vital preventive action is giving up smoking. The single most
effective approach to avoid developing emphysema and other lung problems is to
stop smoking if you are a smoker.
2. Prevent being around secondhand smoke: As
dangerous as smoking itself can be, secondhand smoke can also be. By staying
away from smokers or requesting that they not smoke near you, you can reduce
your exposure to secondhand smoke.
3. Avoid air pollution:
Air pollution can irritate the lungs and raise the risk of emphysema both
indoors and outside. As much as you can, try to prevent or reduce exposure to
air pollution.
4. Use protective equipment: To
lower your risk of getting emphysema, use protective equipment, such as a mask
or respirator, if your job exposes you to chemicals or dust.
5. Regularly examine your health
Emphysema and other lung disorders can be identified early through routine
check-ups with your doctor, allowing for early intervention and treatment.
A healthy lifestyle that includes regular exercise, a
well-balanced diet, and enough sleep can also assist to enhance lung function
and lower the chance of developing emphysema.
In conclusion,
emphysema is a chronic respiratory condition that has a negative effect on a
person's quality of life. The disease's progression can be slowed down and
results can be improved with early detection and treatment. It's critical to
get medical care right away if you believe you or a loved one may have
emphysema.
