What is COPD?

Chronic Obstructive Pulmonary Disease (COPD) is an umbrella term, used to describe a group of progressive lung diseases, including emphysema, chronic bronchitis, refractory (non-reversible) asthma, and some forms of bronchiectasis. Most people with COPD usually have both emphysema and chronic bronchitis.

COPD causes obstructed airflow from the lungs and results in symptoms such as shortness of breath, chronic cough, and wheezing.

Symptoms may be mild at first, beginning with coughing and shortness of breath. As the disease progresses, it can become increasingly difficult to breathe.

How does COPD occur?

COPD is mainly caused by cigarette smoking. The longer one smokes the greater the risk of contracting COPD. Regular inhaling of second-hand smoke can also cause COPD.
Prolonged exposure to air pollutants, dust, workplace fumes, biomass smoke such as wood smoke too are causes of COPD.

When we breathe in, oxygen-rich air goes down the windpipe and into small bronchial tubes or airways located in the lungs. These bronchial tubes branch off into numerous tinier tubes which are known as bronchioles. At the end of the bronchioles are some small, round air sacs called alveoli, which have tiny blood vessels known as capillaries. When the air enters the alveoli, oxygen travels through the capillaries and then into the bloodstream and carbon dioxide moves into the alveoli so we can breathe it out.

What smoking or air pollutants do is damage the walls between the air sacs so that they become weak over time, and their walls break open. This creates one large air sac, instead of the multiple tiny ones making it more difficult for the capillaries to absorb enough oxygen and for the body to expel the carbon dioxide. As a result, the affected person struggles to breathe.

What are the causes of COPD?

The causes of COPD include:

  • smoking cigarettes
  • exposure to fumes from burning fuel for cooking and heating in poorly ventilated homes
  • prolonged exposure to air pollutants, dust, workplace fumes
  • secondhand smoke
  • Infectious diseases that destroy lung tissue in patients

Who is prone to COPD?

People who are prone to COPD include:

  • those who smoke regularly
  • those who are exposed to secondhand smoke from tobacco
  • injection drug users
  • those who have immune deficiency syndromes
  • those who have connective tissue disorders
  • those who suffer from genetic problems such as Salla disease

What are the symptoms of COPD? How is COPD diagnosed?

The early symptoms of COPD include

  • shortness of breath, especially after exercising
  • recurrent cough with mucus
  • needing to clear your throat often, especially first thing in the morning
  • fatigue

As lungs get more damages the symptoms become more severe:

  • shortness of breath, after even mild exercise such as walking up a flight of stairs
  • wheezing or a whistling or squeaky sound while breathing
  • chest discomfort or tightness
  • chronic cough, with or without mucus
  • need to clear mucus from your lungs every day
  • frequent colds, flu, or other respiratory infections
  • lack of energy

In advanced stage the symptoms of  COPD include:

  • swelling of the feet, ankles, or legs
  • weight loss

Diagnosis

 

A general practitioner can diagnose COPD, however, if your condition is too severe he may refer you to a pulmonologist. The doctor will start the diagnosis by asking you about your habits such as smoking, your lifestyle, i.e., if you are exposed to secondhand smoke, air pollution, dust, and chemicals on a daily basis, and your past medical history. He may suggest you undergo some tests such as:

  • Spirometry to test of how well your lungs work.
  • Chest x-ray which can show emphysema, one of the main causes of COPD and also rule out other lung conditions or heart failure.
  • Arterial blood gas test, which measures the oxygen level in your blood.
  • CT scan of your lungs which can help detect emphysema and determine if you might benefit from surgery for COPD.

What are the complications of COPD?

The complications of COPD include:

What is the treatment of COPD?

Medical Treatment for COPD

If smoking is the cause of COPD, the doctor will ask you to stop smoking immediately. He may then, based on the severity of your condition, prescribe bronchodilators which are to be taken with inhalers. Bronchodilators relax the muscles around your airways, antibiotics, inhaled steroids, and oral steroids. If your condition is very severe, the doctor may further suggest oxygen therapy and pulmonary rehabilitation program. For extreme cases, surgery may be required, which can include lung transplant.

Exercise

It may seem difficult to exercise as you have trouble breathing due to COPD, but exercising regularly can improve your overall strength and endurance and also strengthen your respiratory muscles. It is highly advisable to discuss with your doctor which exercises will be appropriate for you.

Exercises which are usually recommended for COPD patients include walking, cycling, Tai Chi. For people with mild COPD jogging, rowing, skating, water aerobics are some good forms of exercises.

Along with COPD, there is a breathing problem. I would like to discuss about the use of BiPAP machines along with oxygen intake for my situation. should I use BiPAP AVAPS(average volume assured pressure support) or should i just go with BiPAP.

How can you differentiate between asthma and COPD.

Hi. I understand your concern s. Basically whether COPD or asthma it depends on her lung function. She will need to undergo a pulmonary function test to assess her lung functions. If optimum you can decide about surgery. Consult a pulmonologist for the same

Copd mainly in smokers. Usually start after 50 yrs of age. Risk for need of ventilator support after surgery is there
Dr. Namrata Jasani

A pulmonary function test is required to differentiate between asthma and COPD along with clinical history. COPD has to be well controlled before surgery especially if it is under general anaethesia.

Hi. I understand your concern s. It depends on how severe is the COPD . if it is mild then you can use N 95 mask while at work. Better to get assessment of COPD by a pulmonary function test if not done earlier. Consult a pulmonologist for the same.

Many times it is not possible completely to go off the work in many patients though it produces some harmful effects .
Hence it is just the question of how safley the job is done with out causing harmful effects .
So if u feel u can do it that way it is ok.
Also try to use some face mask like protective devices to reduce the dust exposure
