Chronic Obstructive Pulmonary Disease (COPD) is becoming a growing health concern among South African women because of misdiagnoses and inappropriate treatment. This is according to Chief Scientific Officer & Medical Director, Southern Africa at Novartis South Africa, Dr Nicola Lister.
There is still a lack of awareness around the risk factors and symptoms of COPD among South African women, and we find that in many cases, women with COPD are incorrectly diagnosed and treated for upper respiratory infections or asthma, instead of COPD. Both primary physicians and women in South Africa need a greater awareness of the risks, diagnosis and treatment of COPD in women.
COPD, which includes a range of progressive lung diseases including emphysema and chronic bronchitis, typically develops slowly and usually becomes apparent after 40 or 50 years of age. The most common symptoms of COPD are breathlessness (or a “need for air”), chronic cough, and sputum (mucous) production, reports the World Health Organisation (WHO). Daily activities, such as walking up a short flight of stairs or carrying a suitcase, and even daily routine activities can become very difficult as the condition gradually worsens.
A chronic issue
COPD is a major cause of illness and death around the world and is predicted to become the fourth leading cause of death by the year 2030. It is estimated to affect over 329 million people and, although it is often perceived as a disease of the elderly, around 50% of patients are estimated to be below 65 years of age. Up to 70% of people living with COPD are also at increased risk of death and disability due to cardiovascular disease.
In South Africa’s urban areas, growing numbers of women are smoking, increasing the likelihood that women with respiratory symptoms have COPD. While the main cause of COPD is exposure to tobacco smoke (either active smoking or secondhand smoke), other risk factors include exposure to indoor and outdoor air pollution.
Smoke from biomass fuel is another risk factor for COPD, particularly among women who spend several hours a day cooking in poorly ventilated kitchens. Across Africa, where millions of people still cook over open fires, the risk of COPD may be higher than average. Studies in South Africa, Nigeria, Malawi and Cape Verde have indicated the prevalence of COPD may be as high as 24.8%, with men and women equally affected, even though women across much of Africa were less likely to smoke than men were.
Occupational factors can also increase COPD risk, particularly in cottage industries where employees are exposed to dust and fumes, such as brick-making, leather working, fish smoking and tobacco curing, plastics manufacturing or spray painting.
A women’s issue
Unfortunately, women are less likely to be correctly diagnosed with COPD than men even though co-morbid asthma, anxiety, depression and osteoporosis are more common in women than men with COPD, and women experience around 17% more exacerbations than men. Exacerbations are serious episodes of increased breathlessness, cough and sputum production that last from several days to a few weeks. These episodes can be seriously disabling and result in a need for urgent medical care or hospitalisation, and can sometimes lead to death.
Risk avoidance, such as stopping smoking, is the most important step to take to reduce the chance of developing COPD and to lessen the symptoms of those who already have COPD. It is also important that women are made aware of the symptoms of COPD and consult their doctors if they develop these symptoms.
Correct diagnosis is crucial to avoid potentially unnecessary treatment with antibiotics or inhaled steroids, which may have adverse side effects and offer little benefit for the COPD patient. While COPD is not curable, appropriate treatment can relieve symptoms, improve quality of life and reduce the risk of death.
Greater awareness is also needed in the healthcare community of the increasing burden of COPD in women to improve disease diagnosis and treatment. With the correct diagnosis and appropriate medication and management programmes, the patient’s outcomes can be improved.
To support patients living with COPD, Novartis hosts a patient information site ‘COPD: Life is Calling’ with advice on healthy living and managing the symptoms of COPD, and inspiring stories about people living with COPD.
