Why you should NEVER exercise with elevated blood sugar! (This is why you can’t stick to any exercise routine and always feel tired)

Exercising with high blood sugar levels can potentially cause your blood sugar levels to rise even further due to various reasons:

  1. **Insulin Resistance:**
    When blood sugar levels are elevated, your cells may become increasingly resistant to the effects of insulin. Insulin is the hormone responsible for transporting glucose from the bloodstream into cells to be used for energy. When insulin resistance occurs, glucose remains in the bloodstream at higher levels, leading to persistent high blood sugar levels. Exercising when insulin resistance is present may not effectively lower blood sugar levels as expected.
     
  2. **Decreased Exercise Performance:**
    High blood sugar levels can affect your exercise performance and lead to feelings of fatigue, weakness, or lethargy. This can make it difficult to engage in physical activity effectively and may increase the risk of injury.
     
  3. **Limited Glycogen Storage:**
    With type 2 diabetes, insulin is not effectively signalling cells to take up glucose for energy due to high blood sugar levels, your body may have limited capacity to store glucose as glycogen in the muscles and liver. This can hinder the ability of exercise to lower blood sugar levels, potentially causing them to remain elevated or even increase.

  4. **Delayed Impact of Exercise:**
    While exercise is generally beneficial for improving insulin sensitivity and lowering blood sugar levels in the long term, the immediate impact of physical activity on blood sugar levels might not be as significant when starting with high blood sugar levels.
    It may take time for regular exercise to have a more pronounced effect on blood sugar management.

  5. **Dehydration:**
    Elevated blood sugar levels can contribute to increased urination and dehydration. Exercising with high blood sugar levels can exacerbate dehydration, as you may be losing fluids through sweat while already being dehydrated. This can further strain your body and potentially lead to complications.

Exercise is great for diabetics, however, if you have persistently elevated blood sugar levels, it is important to manage your blood glucose levels effectively through medication, healthy eating, and lifestyle changes.

Before starting any exercise regimen, consult with your healthcare provider or a diabetes educator to develop a safe and effective plan that takes your blood sugar levels into consideration. Monitoring your blood sugar levels regularly, especially before and after exercise, can help you understand how physical activity impacts your diabetes management.
