Relationship between Diabetes and Fitness

If you’re going to exercise, you need to see how it affects your blood sugar. If you have diabetes or prediabetes, try this simple experiment. Check your blood sugar values before you exercise, and then take it again afterwards to see and understand what exercise does to your blood sugar. During exercise, insulin needs to be available to help sugar get into your cells, but must also keep a low profile because a high level of insulin in the blood tells the liver not to release glucose, which you need to keep your energy up. So lets learn some basics on the relationship between diabetes and exercise and see how you can use this to your advantage.

‍Exercise and Blood Glucose 

Diabetes is of two types - one where the insulin is not secreted in a sufficient quantity and second where your body cannot use the insulin that is secreted in sufficient quantity. The latter is also known as insulin resistance. Either way, the result is high levels of blood sugar. When you exercise, your muscles take up the glucose from your blood for energy. Thus regulating your blood glucose levels. Even if you are insulin resistant, exercising improves the effect of insulin, meaning it can also correct insulin resistance with time.

Several different factors play a role in lowering or raising the blood sugar levels in one’s body. Some of the major aspects would be – diet, stress, sleep cycle, exercise, etc. Yes, all of these things and a lot more can play a huge role in the overall sugar levels. One of the major things each doctor emphasizes when a person is diagnosed with diabetes is the importance of diabetes fitness. However, this exercise would also need to be well-planned and curated specifically to the needs of each person and how their bodies might respond to particular workout regimes. That being said, each day, before a workout, the blood sugar levels might be different, this might also alter the plans in the schedule and type of exercises. 

Here is how exercise can affect blood sugar levels:

1. The effect of any physical activity like walking, running, or even hardcore strength training can play a role in blood sugars as the muscles use all the extra glucose in the body in the form of energy during exercises. These activities can lower blood sugar levels for up to 24 hours, making the body more sensitive to insulin. 
2. Being active regularly can provide long-term health benefits to a person with diabetes as it helps lower the overall HbA1c levels. 

Type 2 Diabetes and Exercising

In Type 2 diabetes, the insulin that is secreted is not effective and fails to regulate blood sugar levels. The risk of type 2 diabetes is greater in overweight individuals. It is also harder to control weight gain in individuals who have type 2 diabetes. It is proven that losing weight and maintaining a healthy weight helps in regulating blood sugar levels. Exercising, as mentioned earlier, can help regulate your blood glucose levels. It can also help you to maintain a healthy weight by increasing your muscle mass.

Many times, when a person with diabetes has hyperglycemia, they are advised to drink a lot of water and maybe go take a walk. Of course, this is subjective to the person, and the exact blood sugar reading on the glucometer. However, the benefits of exercise for a person with diabetes cannot be overstated as exercise and blood glucose are highly connected. There are several obvious and even underlying advantages to working out as it helps in lowering the blood sugars but also in several other ways like – improving cholesterol levels, strengthening muscles and bones, reducing stress with the release of endorphins, etc. It also improves the body’s sensitivity to insulin. 

Other benefits of exercising for a person with diabetes could be:

1. A lower HbA1c by almost 0.7 percentage points in different people. 
2. Increased activity by the heart resulting in lesser cardiovascular diseases. 
3. Lowering the bad cholesterol levels in the body
4. Using the excess sugars present in the bloodstream, thus reducing the need for insulin, etc

These are a few of the exercises that you can be engaging in if you have diabetes:

1. Cardio exercises like – aerobics, jogging, walking, dancing, Zumba, etc are known to be beneficial in lowering the blood sugars among people with diabetes. Check your sugar levels before any hardcore cardio exercises to ensure to not drop significantly low.
2. Strength training – combined with cardio, these exercises can prove to be highly beneficial for the muscles 
3. Resistance training – this form of workout particularly helps to reduce abdominal obesity and insulin resistance. In tandem with cardio, these work best.
4. Walking – if you are not too much into working out, walking in the park or on the terrace may also help. Walking is associated with lower levels of heart disease.

The 15-15 Rule

There are a few simple steps to this rule

1. Check your blood sugar levels
2. For a reading lower than 100 mg/dL, take about 15-20 grams of carbs to raise it

• 4 glucose tablets (4gms per tablet)
• 15 grams of glucose gel
• ½ cup of juice or soda
• 1 tablespoon sugar or honey

3. Check sugar levels after 15 minutes. If it is still below 100 mg/dL, repeat the intake of 15grams of carbs. 
4. This process should be conducted every 15 minutes until the blood sugar levels rise up to at least 100mg/dL

This process is important because low sugar spells are often known to be fatal as a person can lose consciousness. This is why it becomes important to treat them as soon as the level falls down below a certain benchmark. Additionally, especially before working out, this process becomes vital as exercising with low blood sugar can also result in severe complications. Ensure that your sugar levels are high enough to be able to work out with the strength, energy, and adequate support from your body.

FAQs

Does walking lower blood sugar immediately?

Walking is a good way to burn extra calories and use the muscles of the body. The biggest muscle groups – the legs are used which take up a lot of the extra sugars floating within the bloodstream. This results in lowering the blood sugars. While it may not be immediate, it does happen pretty quickly.

What is the best time for diabetics to exercise?

By calculation, the best time to exercise would be 2-3 hours post meals when the blood sugars are on the higher side. This would lead to a lesser risk of hypoglycemia. Mornings, after a snack as decided with your dietician might also be a good idea. Read more about the type 2 diabetes exercise.

What is the importance of warm up before exercise?

Warming up is an important step that should not be skipped before any form of exercise as it helps to heat up the muscles to an extent that they do not lock up or freeze while working out. Loosen up the rigid muscle groups within the body before you begin something extensive and help the oxygen flow freely all throughout. Read more about why warm up is important before any exercise.
