Hello,
Diabetes and high blood pressure are not a “bad combination” for exercise. Regular activity can improve insulin sensitivity, glucose control, blood pressure, fitness and weight management.
Walking is an excellent starting activity, but it is not the only suitable exercise. Combining aerobic and resistance training may provide greater glucose benefits than either type alone.
See our guide to diabetes and exercise.
A moderate pace generally means you can speak in short sentences but cannot comfortably sing. Warm up and cool down for several minutes.
During resistance exercise, exhale while lifting or pushing and inhale while returning. Holding the breath can cause a sharp blood-pressure rise.
Stop exercising for chest pressure, severe shortness of breath, fainting, new neurological symptoms or an unusual severe headache. Blood pressure above 180/120 mmHg with chest pain, breathing difficulty, weakness, numbness, vision change or difficulty speaking is an emergency.
Exercise often lowers glucose during activity and for hours afterward. Insulin, sulfonylureas and meglitinides can increase exercise-related hypoglycemia risk.
Glucose can sometimes rise after intense activity. See why blood sugar may rise after exercise.
Drink enough water to avoid dehydration, with additional fluid during heat, heavy sweating or prolonged activity. Do not force excessive amounts.
Water does not create glucose, replace exercise energy or prevent hypoglycemia. People at risk of low glucose need an individualized food and medication plan.
Obtain guidance before vigorous exercise or heavy resistance work if you have uncontrolled hypertension, chest symptoms, cardiovascular disease, advanced eye disease, kidney disease, severe neuropathy, a foot ulcer, frequent hypoglycemia, dizziness or fainting.
Severe retinopathy may require avoiding vigorous lifting, breath-holding, jumping and jarring activity. With neuropathy or foot problems, use well-fitting footwear, inspect the feet and consider cycling, swimming or seated exercise.
Review our diabetic foot-care guidance.
Adjust the plan to fitness, blood pressure, glucose medicines and complications. Consistency is more useful than beginning with a long, exhausting workout.
Start with moderate aerobic activity, then add correctly performed resistance exercise. Heavy maximal lifting is unnecessary, but strength exercise should not be prohibited solely because someone has diabetes and hypertension.
Monitor blood pressure and glucose responses, breathe continuously, stay appropriately hydrated and increase activity gradually. Ask your healthcare team for an individualized plan when either condition is poorly controlled.
Hope this helps.
