Occupational Lung Disease in Sharjah
Medically reviewed by Dar Al Kamal Team
What is occupational lung disease?
Occupational lung disease covers any breathing condition linked to the air a person breathes at work. It falls into three broad groups, each behaving differently.
- Work-related asthma. Either new asthma caused by a substance at work, or existing asthma made worse by the workplace. Common triggers include flour and grain dust, wood dust, isocyanates in spray paints and foams, cleaning chemicals, hair-salon products, latex and welding fumes.
- Dust diseases. Scarring of the lung from mineral dust built up over years. Silicosis follows exposure to crystalline silica from cutting, grinding and polishing stone, quartz worktops, concrete and tiles. Asbestosis and pleural thickening follow asbestos exposure, often decades earlier. Some metal dusts and fumes, including hard metal and beryllium, cause their own patterns.
- Hypersensitivity pneumonitis. An immune reaction in the small air sacs to organic material such as mould in stored crops or contaminated air-handling systems, bird proteins, or metalworking fluids.
A specific point few people expect: in work-related asthma, symptoms often improve on days off and on holiday and return within days of going back. That weekly and seasonal pattern is often the strongest clue to the cause.
Who needs it
This assessment suits adults whose cough, wheeze, chest tightness or breathlessness began or worsened after starting a job, and those who notice their breathing eases away from work. It also suits workers with years of dust exposure who want their lungs checked, people referred with a chest X-ray or CT showing changes suggestive of dust, and anyone with a runny nose and itchy eyes at work, which often comes before occupational asthma.
In the UAE, the jobs most worth mentioning are construction, stone and marble cutting, quartz worktop fabrication, sandblasting, tunnelling, welding, spray painting, bakeries, cleaning, hairdressing, carpentry, farming and poultry work. Heat and heavy physical work increase breathing rate, so more dust reaches the lungs during a shift. Smoking, including shisha, dokha and vaping, adds to workplace damage and makes the picture harder to read. The wider range of breathing symptoms is described on the Pulmonology page.
What happens
Your pulmonologist at Dar Al Kamal Hospital, Sharjah begins with a full work history: every job from your first employment, the tasks you did, the materials handled, whether dust was visible, how ventilation and extraction worked, what respiratory protection you wore, and whether colleagues have similar symptoms. Hobbies, birds and home conditions are also covered.
Tests are chosen to answer the question at hand:
- A peak-flow diary at work and away. You are given a small handheld meter and record your best of three blows about four times a day, on working days and days off, over a set period agreed with your doctor. A clear drop on working days that recovers on rest days strongly supports work-related asthma.
- Spirometry and full pulmonary function testing, measuring airflow, lung volumes and gas transfer.
- Chest imaging, through X-ray, CT scan and chest imaging, to look for dust-related scarring, nodules or pleural plaques.
- Bronchoscopy in selected cases, to sample the airways.
Where a dust disease or hypersensitivity pneumonitis is found, longer-term care follows on the interstitial lung disease page, and asthma care is described under asthma treatment. Pulmonary rehabilitation and a thoracic surgeon are available by referral when needed.
Preparing for it
Write out your job history with dates, employers, tasks and materials. Bring safety data sheets for chemicals you use, if your workplace provides them, and photographs of your work area or protective equipment. Bring all previous chest X-rays, including residence-visa screening films or reports, and any workplace health-surveillance results.
Bring your inhalers in the devices you use. For lung function tests, wear loose clothing and avoid smoking on the day.
Afterwards
Your pulmonologist explains whether the findings point to a work cause and what that means for your health. Reducing exposure is the central step: better extraction, wet cutting methods for stone, and a properly fitted respirator rather than a loose paper mask. Fit-testing matters, since a beard or a poor seal lets dust pass around the edges. Some people move to a different task or workplace.
If your employer requests a medical letter on fitness for work, your pulmonologist can discuss what can be provided.
Call the hospital on 06 599 7777 if your breathing worsens over days, your reliever inhaler is needed more often, or you develop fever with cough.
Call emergency services or go to the nearest emergency department if you are breathless at rest, cannot speak in full sentences, your lips turn blue, or you have chest pain.
Cost and insurance
Most UAE insurance plans cover pulmonology consultations, spirometry and chest X-ray requested for symptoms. CT, full lung function testing and bronchoscopy often need insurance pre-approval, and some employers arrange occupational assessments separately.

Frequently asked questions
How do I know if my asthma is caused by work?
Asthma is likely to be linked to work when symptoms improve on days off or holidays and return after going back. A peak-flow diary kept on working and rest days, reviewed by a pulmonologist, is the most practical way to show the pattern.
Can working with stone or quartz worktops damage the lungs?
Cutting, grinding and polishing stone, concrete and engineered quartz releases fine crystalline silica, which can scar the lungs and cause silicosis. Wet cutting, dust extraction and a fitted respirator reduce exposure, and anyone with years of such work and a cough or breathlessness should have lung function tests and a chest X-ray.
Is a paper dust mask enough protection?
A loose paper mask gives little protection against fine silica or chemical fumes, because dust passes around the edges. A properly rated respirator that has been fit-tested on your face, combined with extraction and wet methods at source, gives far better protection.
What are the risks and limitations of occupational lung disease tests?
The tests carry few risks: spirometry can cause brief light-headedness, chest X-ray and CT involve a small radiation dose, and bronchoscopy can cause a sore throat, cough or occasionally bleeding. The main limitation is that a peak-flow diary depends on regular, honest readings, and early dust disease may not show on a chest X-ray.
My chest X-ray for residence was normal — does that mean my lungs are fine?
A normal screening chest X-ray is reassuring but does not measure how well the lungs work, and early dust disease or work-related asthma can be present with a normal film. Lung function testing and a work history give a fuller picture if you have symptoms.
Can I keep working if I have occupational asthma?
Many people with occupational asthma continue working once exposure to the trigger is removed or controlled, sometimes by moving to a different task. Your pulmonologist discusses the options, since continued exposure to the cause can make asthma persistent.
Does shisha or vaping make work-related lung disease worse?
Smoking shisha, dokha or cigarettes and vaping all irritate and damage the airways, adding to the harm from workplace dust and fumes. Stopping reduces the total load on the lungs and makes test results easier to interpret.
Is an occupational lung assessment covered by insurance?
Most UAE insurance plans cover a pulmonology consultation, spirometry and chest X-ray for symptoms, while CT, full lung function tests and bronchoscopy often need pre-approval. Confirm your cover with Dar Al Kamal Hospital, Sharjah on 06 599 7777.
