COPD

What is COPD?

COPD narrows the airways and leaves the air sacs less able to move air, so breathing takes more effort than it used to. The name is short for chronic obstructive pulmonary disease, and two patterns of damage sit under that one label: emphysema, which damages the air sacs, and chronic bronchitis, which inflames the airways, as NICE guideline NG115 sets out.

Most people who develop it are middle-aged or older, and either smoke now or have in the past. Years of exposure to harmful dust or fumes can also cause it, the NHS guidance on COPD notes. Chronic obstructive pulmonary disease treatment in Dubai starts with the same question: is this COPD, or is something else causing the breathlessness?

There is no cure, and the damage already in the lungs cannot be reversed. Care aims to slow the disease and to control the symptoms, as NHS COPD treatment guidance describes. It is one of the lung conditions we treat.

What are the symptoms?

Symptoms build over months and years. A cough that keeps returning, or a flight of stairs that now needs a pause at the top, usually gets blamed on smoking, age or a chest infection that never fully cleared.

When COPD is the cause, several of these usually appear together. They are the symptoms that NICE's COPD recommendations list for anyone over 35 who smokes or has smoked.

• Breathlessness when you walk, climb stairs or go up a slight hill.
• A cough that hangs on, or returns every winter.
• Phlegm in the chest, often worse in the morning.
• Wheeze, a whistling sound when you breathe out.
• Tiredness, or tiring sooner than you used to on the same walk.
• Chest infections that keep on returning.

Breathlessness when you are active is usually the first to show. A morning cough and phlegm get written off for years.

If that sounds familiar, ask for a breathing test instead of another course of antibiotics. The guide to breathlessness that needs a specialist covers the other causes worth ruling out first.

How is COPD assessed?

The appointment runs in a set order, and each result decides the next test.

1. Your history: how long the breathlessness has been there, whether you smoke or smoked, and what you have breathed at work.
2. An examination of your chest, and questions about weight loss, ankle swelling, waking breathless or coughing up blood.
3. Your oxygen level, from a clip on the finger. Pulse oximetry shows how severe it is, and it does not make the diagnosis on its own.
4. Spirometry, once and again after an inhaler that opens the airways. You blow into a machine that records how much air you push out and how quickly, and the guide to what spirometry measures explains what to expect.
5. A review of any X-rays, scans or reports you already have. NICE's COPD recommendations also ask for a BMI, a full blood count and a chest X-ray at this first assessment.
6. Further testing when spirometry leaves a question open: pulmonary function tests measure lung volumes and how well gas crosses into the blood, and home peak flow recorded over a few weeks helps separate COPD from asthma.

The after-inhaler result confirms COPD: NICE's COPD recommendations set the ratio at FEV1 over FVC, with a value under 0.7 meaning obstructed airflow, and grade breathlessness from 1 to 5 on the Medical Research Council scale, from breathless only on strenuous exercise to too breathless to leave the house. That grade shapes the plan, and no single result is decisive: history, examination and the after-inhaler figure are read together.

How is COPD managed?

Care is planned person by person, and it usually combines several things that work together.

Inhalers are the usual treatment when COPD affects your breathing. Taken as prescribed, they can make breathing easier and help prevent bad flare-ups, as the NHS guidance on living with COPD explains.

If you smoke, stopping is the step that matters most. The NHS COPD treatment guidance puts it plainly: for someone with COPD who smokes, stopping is "the most important thing you can do".

Pulmonary rehabilitation is a supervised course of exercise and education. It can improve how far you walk before breathlessness stops you, and how you feel day to day.

Vaccination belongs in the plan too. Everyone with COPD is encouraged to have the yearly flu jab and the one-off pneumococcal vaccine.

Ask for that plan in writing, with what to do when your breathing worsens, which medicine to take first and when to call the clinic. Bring it to each review.

If the symptoms above sound like yours, you can book an appointment for a review in Dubai or by video, and no referral is needed to ask.

When to get help urgently

A flare-up means the breathlessness, the cough or the phlegm gets worse than usual, enough to need more than the regular inhalers. The plan agreed with you should say what to do first and who to call.

Some signs mean an ambulance instead of the next clinic appointment. In the UAE, the ambulance number is 998, according to the UAE Government portal.

Call it, or go to the nearest emergency department, if you are severely breathless or your breathing gets worse over hours, if your lips or fingertips look blue or grey, if you become confused or unusually drowsy, or if you have chest pain.

Do not wait for a scheduled review when any of those appear. Breathlessness that is worse than usual, but not severe, is still worth a call. The plan can then be adjusted before the next flare-up.
