Asthma in Adults (Nigeria Guide)
Breathlessness, wheeze, and chest tightness โ achieving asthma control in Nigeria
Asthma is a chronic inflammatory airway disease characterised by episodic breathlessness, wheeze, chest tightness, and cough โ typically worse at night or early morning. It affects approximately 6โ8% of Nigerian adults. In Nigeria, asthma is frequently undertreated โ many patients rely only on short-acting reliever inhalers (salbutamol/Ventolin) without the anti-inflammatory preventer therapy that controls underlying inflammation. This leads to preventable attacks, hospitalisations, and deaths. Well-controlled asthma means living a fully active life.
Signs and Symptoms
โ Recurrent episodes of breathlessness, wheeze (high-pitched whistling sound when breathing), chest tightness, and cough
โ Symptoms worse at night or early morning
โ Symptoms triggered by cold air, exercise, dust, smoke, respiratory infections, strong emotions
โ Symptoms that vary from day to day โ 'good days' and 'bad days'
โ Rapid relief with a salbutamol (blue) inhaler confirms the diagnosis
โ Persistent dry cough as the only symptom in some โ 'cough-variant asthma'
When to Seek Help
Emergency โ call 112Severe breathlessness at rest, unable to speak in sentences, blue lips or fingertips (cyanosis), peak flow <50% of best, not improving with repeated reliever inhaler โ acute severe or life-threatening asthma
Same dayAsthma attack requiring reliever inhaler more than every 4 hours, or night waking with breathlessness
Within 1 weekUsing reliever inhaler more than 2 days per week โ asthma not controlled, preventer therapy needs review
RoutineAsthma review every 6โ12 months โ check inhaler technique, step up or down treatment, assess control
SoonNew onset breathlessness and wheeze in an adult over 40 with smoking history โ must exclude COPD and cardiac causes
Tests & Diagnosis
๐งช Peak expiratory flow (PEF)
Simple bedside test โ patient blows as hard and fast as possible into a peak flow meter. Reduced and variable PEF supports asthma. Morning dipping (lowest PEF in the morning) is characteristic. Every asthma patient should have a peak flow meter
๐งช Spirometry
FEV1/FVC ratio <0.7 = airflow obstruction. Significant reversibility (โฅ12% and โฅ200 ml increase in FEV1 after salbutamol) confirms asthma. Available at most tertiary hospitals in Nigeria
๐งช Bronchial challenge test
Methacholine or mannitol challenge โ for suspected asthma with normal spirometry. Rarely available in Nigeria
๐งช Chest X-ray
Normal in asthma โ used to exclude other causes (pneumothorax, pneumonia, heart failure)
๐งช Total IgE and blood eosinophil count
Elevated in atopic (allergic) asthma โ guides biologic therapy decisions in severe asthma
๐งช FeNO (fractional exhaled nitric oxide)
Measures airway inflammation โ high FeNO suggests steroid-responsive eosinophilic inflammation. Not widely available in Nigeria yet
Frequently Asked Questions
Can I use my blue inhaler every time I'm breathless?
The blue (salbutamol) inhaler relieves breathlessness but does not treat the underlying inflammation. Using it more than 2 days per week means your asthma is not controlled โ you need a preventer (brown, red, or purple) inhaler. Relying only on the blue inhaler without a preventer is a major cause of asthma attacks and death.
Is it safe to exercise with asthma?
Yes โ exercise is beneficial for asthma. Exercise-induced bronchoconstriction (wheeze during exercise) is preventable: take 2 puffs of salbutamol 15 minutes before exercise. Warm up slowly. Swimming is particularly good for asthma as the warm, humid air is less irritating to airways.
Can asthma be cured?
Asthma cannot currently be cured, but it can be completely controlled. With appropriate preventer treatment, most people with asthma have no symptoms, no limitations on activity, and no attacks. 'Controlled asthma' means no night waking, no reliever use (or <2 days/week), normal activity, and normal lung function.
Does asthma get worse with age?
It varies. Some children 'grow out' of asthma (though it often returns in adulthood). Some adults develop new asthma. With good treatment, asthma does not inevitably worsen. Poorly controlled asthma causes progressive airway remodelling (permanent lung changes) โ another reason for consistent preventer therapy.
