During exercise, which glucose level range requires caution due to potential complications when accompanied by symptoms or ketosis?

• A. 6.0 to 7.0 mmol/L
• B. 3.0 to 4.0 mmol/L
• C. <4.0 mmol/L or >15.0 mmol/L with symptoms or ketosis
• D. 10.0 to 12.0 mmol/L

Answer: (C)

During exercise, the body's need for glucose rises, so extreme levels become risky, especially when there are symptoms or ketones present. The combination of very low glucose (<4.0 mmol/L) or very high glucose (>15.0 mmol/L) with symptoms or ketosis signals potential complications: hypoglycemia can impair brain function and performance during activity, and ketosis with high glucose can indicate diabetic ketoacidosis, a serious condition that requires medical attention. Thus, this range is the one to treat with caution and to act on promptly (recheck after intervention for low values; seek guidance if high values with ketosis or symptoms). The other ranges lack the accompanying signs that flag urgent danger, so they don’t carry the same level of immediate risk in this context.
