If you have insulin-resistant (type 2) diabetes, you can benefit from exercise, but exercise caution. Extremes in blood sugar levels and certain neurological or eye conditions can pose unanticipated dangers.
Liver/Glucose Connection
To supply muscles with additional glucose during exercise, the liver releases more glucose. However, if you lack sufficient insulin to handle that glucose in your bloodstream, your blood sugar level might rise after exercising.
Hyperglycemia
Because of this connection, the Joslin Diabetic Clinic recommends not exercising during periods of hyperglycemia when blood sugar levels exceed 250 mg/dl and ketones are present, or when blood sugar alone exceeds 400.
Hypoglycemia
Similarly, low blood sugar levels or hypoglycemia can lead to insulin reactions after exercise. As a result, exercise at least an hour after eating. Carry glucose tablets, drink enough liquids, and wear comfortable shoes.
Neuropathy
Nerve damage in the extremities, or neuropathy, could pose a danger because your feet lack sensation, according to Web MD. Without sensation, you might trip or fall.
Eye Damage
Similarly, if you have a severe eye problem related to diabetes, exercise may exacerbate that condition. For these reasons, consult your physician before beginning an exercise program.
