Blood glucose at 7.1 generally refers to a blood glucose level of 7.1 mmol/L. Whether a blood glucose level of 7.1 mmol/L is high for a 70-year-old depends on the time of measurement. The normal range for fasting blood glucose in healthy adults is 3.9 to 6.1 mmol/L. For a 70-year-old, a fasting blood glucose level of 7.1 mmol/L is higher than the normal range. The normal range for blood glucose one hour after eating for a healthy person is 6.7 to 9.4 mmol/L, generally not exceeding 11.1 mmol/L. If a 70-year-old has a blood glucose level of 7.1 mmol/L one hour after eating, it is within the normal range and not high. The normal blood glucose level for a healthy person two hours after eating should be less than or equal to 7.8 mmol/L. If a 70-year-old has a blood glucose level of 7.1 mmol/L two hours after eating, it is normally not high. If an elderly person has abnormal blood glucose levels outside the normal range, accompanied by symptoms such as dry mouth, polyuria, and polydipsia, they should be vigilant and suspect the possibility of diabetes. The patient needs to intervene in the hospital as soon as possible to clarify the cause.
