Plan ahead and organise your shopping trips. Avoid carrying heavy bags and only buy what you can carry without getting overly breathless. Consider getting a wheeled shopping trolley.
Friends and family can also help by getting heavier shopping such as washing powder, cleaning products and tinned food. You may wish to think about ordering shopping on line for home delivery, most supermarkets provide this service. This can also be useful if the weather is bad in winter or if you have allergies, when pollen levels are high and your asthma symptoms are worse.
Some of the larger shopping centres hire mobility scooters to help you get around. See the Shopmobility directory for mobility scooters in your area.
If there are times you can’t get out to do your own shopping (for example when you have a chest infection) ask family members to help get perishable foods like milk and bread.
