Running deals with diabetes on a multi-faceted level because it boosts insulin sensitivity, controls blood sugar, aids with weight control, and diminishes the chances of cardiovascular disease, maintaining the diabetes care triad. If on insulin or other glucose-lowering medicines, it's imperative to pre-fuel with 15-30 g of carbs like bananas or toast with nut butter. Ketones present alongside blood sugars north of 250 mg/dL means running is unsafe and should be skipped. Ensuring hydration is important because lack of it increases the risk of elevated glucose levels. Post-run, a balanced snack containing 15-30 g of carbs and 10-15 g protein to help replenish muscle glycogen while staving off delayed hypoglycemia is recommended within half an hour. Skipping foot care is not an option. Pre- and post-foot checks have to be performed for blisters, cuts, or irritation along with regular sock and shoe checks. Solid running shoes should be complemented with moisture-wicking socks, and barefoot movement around the house should be avoided to decrease the risk of injury or infection from poorly clipped toenails. Blood sugar should be checked pre-exercise, during (after 45 minutes or more), and post-exercise, as running is safe within a range of 100-250 mg/dL. When it's under 100 mg/dL, intake food prior to starting the activity. If over 250 mg/dL, check for the presence of ketones; refrain from running if any are found. If shaky, dizzy, sweaty, disoriented, or feeling excessive fatigue, stop running right away. Always have fast-acting carbs on hand such as glucose tablets or fruit juice. Diabetes can be managed through running, but only when combined with proper planning, continuous foot care, and meticulous glucose assessment.
Hey, I'm Jabe Brown, MSc (Nutrition & Functional Medicine), BHSc, BComm, AFMCP, founder of Melbourne Functional Medicine. I work with people living with diabetes who want better glucose control through lifestyle strategies. 1. Why running helps Meeting the ADA target of 150 min moderate or 75 min vigorous activity each week trims HbA1c by almost 0.7 percentage points and improves blood pressure. Moreso, the insulin-sensitising effect of a 30 min run lasts up to 48 h, giving runners a larger post-exercise "glucose window". 2. Fuel You want to check capillary or CGM glucose 15-30 min pre-run. Safe zone: 120-200 mg/dL. If < 100 mg/dL and you use insulin, take 15-20 g of fast carbohydrates (e.g. banana), re-test in 15 min, then start the run. For runs > 45 min: sip 15 g carbohydrate every 25 to 30 minutes. Make sure to monitor frequently (if possible). After the run aim for a mean that hits your recovery target (within 60 min) of 0.8 g carbohydrates per kg of body weight and 0.3 g protein. This can limit late hypoglycemia. 3. This is rather easy. Inspect bare feet before and after every run--check skin colour, blisters, nail edges. Wear seamless socks and a shoe with > 1 cm toe room; replace shoes every 500 km. In addition, bi-yearly podiatry reviews are a good call (earlier if callus, fissure or reduced sensation are experienced) 4. Monitor every 30 min during sessions > 45 mins. Stop and carb up if glucose hits < 75 mg/dL or if tremor, sudden fatigue, or confusion appear. Take 15 g of fast carbs (gel etc.), re-check after 15 min. Best regards, Jabe Brown, MSc https://mfm.au
Running is a great way of cardiovascular exercise that lets you manage your blood sugars even better. While running, muscles use glucose for energy, which in turn reduces the blood sugar even during and after workout. With time, a regular run promotes the potential improvement of insulin sensitivity, meaning the body does not have to work as hard keeping low levels of blood sugar. Heart health, weight management, and mental well-being-all increasingly critical in people with diabetes-are all gotten with running beyond its advantage. Before a run, its advisable to ingest small-sized meal that has highly digestible carbohydrates with a little protein in it. For instance, slice of whole grain bread with peanut butter or keep a banana and little yogurt without provoking blood sugar too high. After running comes refueling energy lost through glycogen with muscle recovery support-from the balanced meal after running; grilled chicken with brown rice and vegetables or smoothie with fruit and protein powder. Timing plays a significant role; eating within 30-60 minutes of your workout optimal recovery and blood sugar balance will take place. Foot care is important for diabetics when running. This is because diabetes reduces the circulation and sensation of nerves in the system, increasing the chances of blisters, sorest, or infections. I also recommend using a well-fitted running shoe because they have good arch support and, to prevent friction, use breathable running socks. It is also advised to do daily inspection especially after runs and look for signs of redness, blistering or cuts. Minor foot injuries can also turn serious if they aren't treated early, so do not ignore the discomfort or changes you notice. It's best to check your blood sugar before your run, especially if you are on insulin or other glucose-lowering medications. You may require a little carb-rich pre-run snack if your blood sugar is less than 100 mg/dL. For long runs, it may also be necessary to check your blood sugar levels while on the run or carry some fast-acting carbohydrates in case of a drop. Check your blood sugar again after the run to see how your body reacted. If you feel shaky, dizzy, confused, or excessively tired, it is a red flag and a sign of hypoglycemia, and you should stop running, sit down, and treat your low blood sugar. Always listen to your body; being proactive helps keep you safe while still enjoying the benefits of running.
Protecting Your Feet While Running with Diabetes Foot care is vital for diabetics, particularly those who run, as diminished circulation and nerve damage heighten the risk of injury. Even tiny blisters or sores can turn serious without timely attention. Always wear well-fitting cushioned running shoes, and check your feet every day for redness, swelling, or cuts. Moisturize to deter cracking, but do not put lotion between your toes, where moisture can lead to fungal problems. Get regularly scheduled foot exams with a podiatrist and consider orthotic inserts if you have foot deformities or high-pressure areas. If all else fails, listen to your body, and don't ignore discomfort. Taking care of yourself early on can prevent complications later on.
