Anemic patients with hypoglycemia should be treated promptly because anemia is more likely to induce cardiovascular and cerebrovascular diseases and even life-threatening if hypoglycemia occurs. If the blood sugar is lower than 2.8 mmol/L without diabetes, it is considered as hypoglycemia and should be treated as hypoglycemia in time regardless of whether it is anemia or not. If you are awake, you can immediately take sweet drinks, sugar cubes and other things that immediately raise blood sugar, and if you are already in a fuzzy state of consciousness at this time, check your blood sugar immediately. If the blood sugar is lower than 2.8mmol/L, you can supplement glucose intravenously, and while supplementing glucose, you should pay attention to monitor the change of blood sugar, and adjust the treatment according to the blood sugar value in time. If diabetes with anemia also appears hypoglycemia, lower than 3.9mmol/L is called hypoglycemia, and the disposal method is the same as above.
