Auntie Liu has recently been tested for fasting blood sugar 6.1mmol/L, although it does not reach the standard of diabetes, but has exceeded the normal indicators, the doctor said it is pre-diabetes, Auntie Liu is confused, this pre-diabetes to treat it? Is it necessary to restrict the diet like diabetes? Blood sugar exceeds the normal range but does not reach the standard of diabetes, called pre-diabetes. The deputy chief physician of the endocrinology department of the hospital said that the normal blood sugar level is below 6.1 mmol/L in fasting and below 7.8 mmol/L 2 hours after meal; the diagnostic criteria of diabetes is when there are symptoms of diabetes, plasma glucose level ≥ 11.1 mmol/l (200mg/dl) at any time or fasting plasma glucose level ≥ 7.0 mmol/l ( 126mg/dl), or no diabetic symptoms, but 2hPG level ≥11.1mmol/l (200mg/dl) in oral glucose tolerance test twice can also be diagnosed as diabetes mellitus. The condition in between normal and diabetes is medically called impaired glucose regulation, also known as prediabetes. If a patient’s fasting blood sugar is between 6.1 and 7.0 mmol/l, it is called “impaired fasting glucose”; similarly, a 2-hour postprandial blood sugar between 7.8 and 11.1 mmol/l is called “impaired glucose tolerance”. If left unattended, these two groups of people will easily progress to diabetes, but if treated positively and with reasonable diet control and exercise, they can return to normal levels. The director pointed out that pre-diabetes is mostly seen in patients with obesity and fatty liver. Fatty liver and diabetes are a pair of “difficult brothers”, fatty liver is a risk factor in the early stages of diabetes, because after having fatty liver, fat droplets in liver cells become larger, making the surface insulin receptors less sensitive, resulting in a weakening of the role of insulin, the conversion of excessive blood sugar into liver glycogen storage is also weakened. And the liver sugar output increases during fasting, and the blood sugar will exceed the normal range. Obesity, mainly abdominal obesity, is often inseparable from fatty liver, which also becomes a risk factor for hyperglycemia. Therefore, patients with fatty liver and obesity should have their fasting and two-hour postprandial glucose and glucose tolerance checked regularly for early detection of impaired glucose regulation and early intervention. Pre-diabetes can also have complications As we know, diabetes itself is not terrible, what is terrible is the complications, and many diabetic patients end up with reduced quality of life or even life-threatening conditions because of various complications.
