Taking Control of Asthma


control of asthma

Asthma is a disease of airways. Airways are the pipe/tube-like structures through which you breathe. In asthma, airways get swollen and secrete a sticky substance called as mucus. Thus, the airway becomes narrow and you find it difficult to breathe. 1

Asthma is generally hereditary, which means it is passes through families. It does not spread from one person to other. it has nothing to do with how you were raised or your relationships or your social status. Asthma is treatable and you can keep symptoms well under control. This booklet helps you to understand asthma and its management in detail.  1

What happens when you have asthma?

cause of asthma

Normal airways are not swollen and the air can pass easily through them.2

In asthma, the airways are swollen and narrowed, so breathing is not easy. Thus, patients develop episodes of coughing, shortness of breath, and wheezing.2

In asthma attack, wind pipes are swollen, narrowed, and full of mucus, which makes airways tight, and air gets trapped in the alveoli. Thus, there is wheeze, cough, and difficulty in breathing.2

Asthma: Causes and Triggering Factors

Causes :

Exact cause of asthma is not known. It is more common if there is a family member with asthma or allergy. Symptoms of asthma may develop at any age. The difficulty with asthma symptoms varies depending on the age at which asthma develops.3

Most asthma patients have mild symptoms and they do not have long-term effect on the body. If the asthma is there for long-term, it may affect lung function. When asthma is there for long-term, it may bring in emotions such as anger, fear, inferiority, depression and guilt. However, you should know that asthma is not an illness which you should be guilty of of scared of; if you take treatment as suggested, you should be OK.3

Triggering Factors for Asthma 

  • Allergens: Some substances like pollen from flowers, animal dander, hair of pets like cat and dog, etc. can trigger asthma 4
  • Dust: Dust and dust mite are important risk factors 4>
  • Paint: Inhaling chemicals present in paints can trigger asthma in some people 5
  • Exposure to cigarette smoke: Cigarette smoke is an important trigger to asthma. Cigarette smoke can not only directly increase risk of asthma but can also make a person more prone to viral infections and make airways more sensitive 4
  • Occupational factors: Exposure to things like grains, flours, cleaning agents, metals, irritants, woods, etc. at work place may trigger asthma 4
  • Overweight and obesity: Incidence of asthma is higher among patients who are overweight 5
  • Pesticides: Exposure to pesticides and insecticides is associated with increased risk of asthma5
  • Viral infections: Some viral infections which cause common cold can trigger asthma4
  • GERD: GERD/gastroesophageal reflux disorder – a disease in which there is possibility of regurgitation of stomach ingredients into wind pipe can trigger asthma5
  • Other triggers: Other triggering factors include stress, exercise and air pollution4

Asthma: Symptoms and Feelings1

Symptoms of Asthma

Symptoms of asthma vary from patient-to-patient. In addition, the severity of symptoms may vary from patient-to-patient or depending on the severity of disease pathology. Everyones feeling about his condition or disease are different, they depend on their threshold of addressing challenges. Many patients describe their breathing as “breathing from the straw”.

  • Can you do any physical activity of your choosing
  • Can attend school or work more or less every day
  • Have fewer asthma attacks
  • Have no or minimal medicine related side-effects

Some Rules

To keep your asthma under control, you have to follow some rules. Here are a few of them:

  • Discuss with your doctor about asthma and how to keep it under control. Educate yourself about the conditions.
  • Make a plan for your asthma control in discussion with your doctor.

Management of Asthma

Lifestyle Changes

Lifestyle changes are very useful in keeping asthma under control. Here are some do’s and don’ts with regards to lifestyle in asthma.

asthma diet do's and donts


Here are some dietary changes that are helpful in asthma management:

Have food rich in vitamin A and Vitamin D. Vitamin A and D make lung tissue stronger and thus helps to fight inflammation and allergy, which are characteristic of asthma. The foods rich in vitamin A include carrots, lettuce, sweet potatoes, fish, milk products, egg, etc. Fish and milk are rich in vitamin D. Vitamin D is also produced by our body on exposure to sunlight.15,16

Have diet rich in Vitamin E. Vitamin E is an antioxidant which helps to fight inflammation.17 It is abundant in food like seeds, nuts and vegetables.18

Have polyunsaturated (very) long-chain fatty acids such as omega-3 PUFAs linolenic acid, eicosapentaenic acid (EPA) and docohexaenoic acid (DHA), and the omega-6 PUFAs are found to have beneficial effects in asthma.17 These are mainly found in sea food.19

Avoid saturated fatty acids such as meat, cheese, ice cream and dairy fat. They can trigger asthma and inflammation.15

Avoid food with medium-chain fatty acids such as coconut oil, palm oil, etc. they are found to trigger asthma.16

Exercise in Asthma

Breathing exercises, especially those which involve holding breath are very helpful in asthma. Breathing exercises are done to decrease rate and volume of breathing, to increase use of lower abdominal muscles, to improve chest movements, to use nose for breathing and to induce relaxation. Breathing exercise benefits you by decreasing over-breathing, decreasing breathlessness, decreasing inflammation, decreasing changes in pattern of breathing and decreasing anxiety.20 Commonly used breath retaining exercises are as follows:

  • Pursed-lip breathing21
  • Diaphragmatic breathing21
  • Inspiratory muscle training (IMT)17

Pursed Lip Breathing: Sit upright, breathe in through nose and slowly breathe out by making pursed lip (like how you make your lips to blow a candle). Duration of breathing out should be at least twice as breathing in. The technique helps you to decrease number of breaths taken in and keeps the airways open for longer duration.22

pursed lip breathing

Diaphragmatic breathing: Lie-down on your back; keep your body relaxed; gently place your hands on your belly; breathe in slowly and breathe out slowly; breathe using your belly instead of chest; observe raise and fall of belly as you breathe in and breathe out. Remember you should only use your belly to breath; so, keep your shoulders, chest and neck relaxed while doing this exercise.22

Diaphragmatic breathing

Inspiratory muscle training (IMT): Inspiratory muscle training is aimed at increasing the strength and stamina of accessory respiratory muscles and diaphragm. It usually involves breathing through a device. IMT helps to decrease oxygen consumption and to increase strength of respiratory muscles. Please consult a therapist to learn this exercise.17

Yoga for Asthma

Yoga is useful in various ways to improve asthma. Here are 8 yoga poses that are helpful in asthma management.23

Monitoring Asthma

Peak Flow Meter

peak flow meter

Peak expiratory flow (PEF) is the measure of how forcefully you can blow from your lungs. PEF helps to evaluates the extent of the airway obstruction. Peak flow meter is measured using simple instrument useful in measuring the functioning of your lung. The device has a mouth piece, a cursor and a measuring scale. PEF is useful in asthma diagnosis, to evaluate improvement, to evaluate how asthma medicines are working and to adjust the medication by your doctor. PEF is useful for the following purposes.24

  • For day-to-day recording of asthma severity
  • To evaluate progress of asthma
  • During an asthma attack
  • After taking asthma drug

Measuring PEFR

To measure Peak Expiratory Flow Rate (PEFR), you have to do the following steps:24

Step 1: Set the cursor to 0

Step 2: Stand up and take a deep inhalation. Close your lips tightly around the mouth piece to ensure there is no leak.

Step 3: Breathe out as hard and forcefully as you can.

Step 3: Notice and record the reading (indicated by cursor) on the measuring scale.

Step 4: Repeat step 1 to 3 for 2 more times to take best of the 3 readings.

You have to maintain the values in a book or paper. Your doctor will interpret and tell you the findings of PEF.

Asthma diary

Maintaining an asthma diary helps you to keep track of your asthma control and medicines that you are taking. You can download an asthma diary from internet, take printout and maintain it.25

Myths and Facts about Asthma

Unfortunately in our country, many consider asthma as a taboo and the patients get stigmatised and guilty about the condition. There are several myths about asthma, which you should not believe. Here are some myths and facts.
