Exercise and Chronic Disease: Get the Facts
From the Mayo Clinic
If you have a chronic disease — such as heart disease, diabetes, asthma, or back or joint pain — exercise can have important health benefits. However, it's crucial to talk to your doctor before starting an exercise routine. He or she might have advice on what exercises are safe and any precautions you might need to take while exercising.
How can exercise improve a chronic condition?
Regular exercise can help you manage symptoms and improve your health. For example:
Heart disease. Strength training can improve muscle strength and endurance, make it easier to do daily activities, and slow down disease-related declines in muscle strength.
Diabetes. Regular exercise can help insulin more effectively lower your blood sugar level. Physical activity can also help you control your weight and boost your energy.
Asthma. Often, exercise can help control the frequency and severity of asthma attacks.
Back pain. Regular low-impact aerobic activities can increase strength and endurance in your back and improve muscle function. Abdominal and back muscle exercises (core-strengthening exercises) help reduce symptoms by strengthening the muscles around your spine.
Arthritis. Exercise can reduce pain, help maintain muscle strength in affected joints and reduce joint stiffness.
What exercises are safe?
Your doctor might recommend specific exercises to reduce pain or build strength. Depending on your condition, you might also need to avoid certain exercises altogether or during flare-ups. In some cases, you might need to consult a physical or occupational therapist before starting to exercise.
If you have low back pain, for example, you might choose low-impact aerobic activities, such as walking and swimming. These types of activities won't strain or jolt your back.
If you have arthritis, the exercises that are best for you will depend on the type of arthritis and which joints are involved. Work with your doctor or a physical therapist to create an exercise plan that will give you the most benefit with the least aggravation on your joints.
How often, how much and at what intensity can I safely exercise?
Before starting an exercise routine, it's important to talk to your doctor about how long your exercise sessions can be and what level of intensity is safe for you.
If you haven't been active for a while, start slowly and build up gradually. Ask your doctor what kind of exercise goals you can safely set for yourself as you progress.
Do I need to take special steps before getting started?
Depending on your condition, your doctor might recommend certain precautions before exercising.
If you have diabetes, for example, keep in mind that physical activity lowers blood sugar. Check your blood sugar level before any activity. If you take insulin or diabetes medications that lower blood sugar, you might need to eat a snack before exercising to help prevent low blood sugar.
