1, resulting in dehydrated hypertonic body.
Hyperglycemia in diabetic patients will cause a large amount of glucose to be excreted with urine, causing osmotic diuresis and dehydration. Dehydration will increase the osmotic pressure of extracellular fluid, and the water in cells will be transferred to the outside of cells, resulting in cell dehydration. If brain cells lose water, it may cause brain dysfunction, and patients may be in a coma.
2. Electrolyte disorder
When the patient has hyperglycemia, the urine volume increases obviously, and a large amount of electrolyte in the urine is taken away, leading to electrolyte disorder. Patients with hyperglycemia are prone to diabetic ketoacidosis due to impaired glucose utilization, increased lipolytic ability and ketone body production.
3, the body is thin and the resistance is reduced.
In diabetic patients with hyperglycemia, glucose can not be well absorbed and utilized by the body and is lost with urine excretion. The body provides energy by decomposing protein and fat, which easily leads to emaciation, fatigue and decreased immunity.
4. Vascular and nervous system complications.
Long-term hyperglycemia in diabetic patients easily damages blood vessels and nerves, which leads to the development of chronic complications such as diabetic nephropathy, retinopathy, diabetic foot necrosis, peripheral neuropathy and cardiovascular diseases.
5. Islet failure.
Long-term hyperglycemia will lead to the stimulation of islet β cells and the decrease of insulin secretion, which will cause diabetes and aggravate it.
6, postprandial hyperglycemia is more harmful.
For diabetic patients, postprandial blood glucose can better reflect the level of blood glucose control than fasting blood glucose, and postprandial hyperglycemia is closely related to cardiovascular complications of diabetes. The higher the postprandial blood sugar, the higher the probability of angina pectoris, myocardial infarction and stroke.
7. Recommended diet for lowering blood sugar
1, Mulberry tea: lowering blood sugar and preventing diabetes. Mulberry leaves can not only protect the pancreas and promote the normal secretion of insulin, but also improve hypertension and reduce cholesterol and triglycerides. Therefore, mulberry leaves can effectively prevent diabetes. Mulberry leaf tea can inhibit the increase of blood sugar after meals, but it has no such effect after meals.
2. Taro: Taro contains effective ingredients such as mucin, magnesium, zinc, vitamin B 1, and it also contains galactan, which can effectively lower blood pressure and cholesterol.
3. guava tea: It can prevent blood sugar from rising. Tea contains guava polyphenols, which can inhibit the activation of enzymes that decompose sugar and slow down the absorption of sugar, so that only a small amount of glucose is slowly absorbed.
4. Onion: The most prominent function of onion is to inhibit the rise of blood sugar. Although blood sugar can be suppressed by chemicals, sometimes the effects of chemicals are too strong, which will lead to hypoglycemia. Onions don't have the immediate effect of chemicals, but blood sugar will not drop again after it drops to normal. In addition, quercetin, a unique yellow pigment component of onion, has strong antioxidant capacity, which can effectively inhibit the oxidation caused by blood viscosity and prevent the development of hypertension and arteriosclerosis.
5, yam: the sticky ingredients in yam can wrap other foods in the intestine, so that sugar is slowly absorbed. This effect can inhibit the sharp rise of postprandial blood sugar, and avoid excessive insulin secretion, so that blood sugar can be better regulated. Yam also contains magnesium, zinc and other effective components necessary for insulin secretion, as well as vitamin B 1 and vitamin B2.
