Fasting blood glucose 5.9mmol / L hunger fast is normal, but also need to be 2 hours after the meal blood glucose or random blood glucose or glycated hemoglobin and other related indicators to determine the synthesis.
Typical symptoms of diabetes are “three more and one less”, i.e., drinking more, urinating more, eating more and losing weight. The normal range of fasting blood glucose is between 3.9mmol/L and 6.1mmol/L. Fasting blood glucose of 5.9mmol/L is in the normal range, and fast hunger may be related to less food and more activity, but diabetes can not be ruled out completely.
If you have the typical “three more and one less” symptoms of diabetes, you can be diagnosed with diabetes if you have a fasting blood glucose of 7 ≥ mmol/l, or a 2-hour postprandial blood glucose of ≥ 11.1 mmol/l, or a random blood glucose of ≥ 11.1 mmol/l, or a glycosylated hemoglobin of ≥ 6.5%.
If there are no symptoms of diabetes, two intravenous glucose doses meeting these criteria are required to confirm the diagnosis.
Diabetes mellitus is a disorder of glucose utilization by peripheral tissues, with increased lipolysis and a negative balance of protein metabolism, which can cause symptoms of easy hunger. In addition, hyperinsulinemia, in which insulin levels exceed normal due to abnormal insulin secretion, can also cause symptoms of fast hunger as well as hypoglycemia.
Therefore, when the phenomenon of fast hunger occurs, it is necessary to go to the hospital for further investigation, whether it is caused by diabetes itself or other reasons.
It is recommended to adopt a habitual lifestyle, appropriate exercise, regular medical checkups, and treatment under the guidance of a doctor if any abnormality occurs.
