Hypoglycemia when you are hungry may be diabetes. The first symptom that appears in some patients is hypoglycemia, which is instead a more common manifestation of diabetes, especially in people who are slightly fatter, or who have parents with genetic disorders in the family, or siblings who are more likely to get diabetes. An early manifestation is hypoglycemia when hungry. It is almost time to eat, such as at 10-12 o’clock, and some patients are also prone to hypoglycemia at 4-5 o’clock in the afternoon. If a person has frequent hypoglycemia, it is likely to be diabetes. But some people like young people also have hypoglycemia symptoms, but its not necessarily that the blood sugar is really low. Some people are sympathetically excited, such as when they are about to eat noon meal, or when they are about to eat afternoon meal, and when they usually play chess or cards and move their brains more, they will have panic and discomfort, and they may get better when they eat something. Therefore when the above symptoms appear, you need to do a glucose tolerance test to clarify the diagnosis
