How can I prevent dangerously low blood sugar levels (Hypoglycemia) during exercise?

If you take insulin or sugar-lowering medications, check your blood sugar before exercising. If it is below 100 mg/dL, eat a small snack containing carbohydrates (a banana or 2 biscuits) before starting exercise. Always carry glucose tablets or something sweet with you.

Why should people with Diabetic Neuropathy be careful when exercising?

The pain of wounds or blisters on the feet caused by diabetic neuropathy may not be felt well. As this can lead to infection and serious complications, soft shoes and thick socks should be worn when exercising, and feet should be checked every day after exercise.

Can diabetes be completely cured by exercising more?

Type 2 diabetes can be diagnosed in its early stages and normalized without medication through regular exercise and weight control (Diabetes Remission). However, since it is not a completely curable disease, if you return to a sedentary lifestyle, your sugar levels may rise again.

How can busy people get their daily exercise time?

If you don't have time to exercise for 30 minutes at a time, you can break it up into 3 10-minute sessions a day. Research has shown that short bursts of exercise can provide the same level of benefits.

Sunil (age 52), a businessman who runs a small shop, came to my clinic last Thursday. He has been suffering from Type 2 Diabetes for 5 years.

"Dr. Priya, I take my diabetes pills as prescribed. But my sugar levels fluctuate constantly. The latest HbA1c report is 8.2%. Everyone tells me to exercise, but I weigh 92 kilos and have osteoarthritis . I have difficulty walking because my legs hurt. How can I exercise?" Sunil explained his helplessness.

I explained to Sunil: "Sunil, exercising for someone with diabetes is just as important as taking pills. When we exercise, our body's insulin sensitivity increases. This means that even with low levels of the hormone insulin, the body's cells can easily absorb the sugar in the blood. As a solution to your knee pain, you can do simple exercises that do not put pressure on the joints (low-impact exercises). Today, let's talk about how diabetics like you who have joint problems or are overweight can choose exercise safely."

🚨 Red Flags that should stop exercising immediately

Although exercise is very beneficial for diabetics, exercise should be stopped immediately if the following dangerous symptoms occur during exercise:

Severe tightness, squeezing, or pain in the center of the chest (this may be a sign of a heart attack).
Severe difficulty breathing or uncontrollable shaking.
Dizziness, fainting, confusion, or blurred vision.
Symptoms of hypoglycemia (excessive sweating, shakiness, hunger, or slurred speech) caused by a rapid drop in blood sugar levels.

💡 Steps to take:

If any of the above symptoms occur, sit down and rest immediately. If your blood sugar level is below 70 mg/dL, immediately drink a spoonful of sugar or fruit juice. If chest pain persists for more than 5 minutes, go to the nearest hospital immediately.
