Diabetes is afflicting people all around the world, particularly type 2 diabetes, which accounts for over 90% of all cases. The pathogenesis of type 2 diabetes is quite complex, involving genetic predispositions and environmental factors, as well as factors like insulin resistance and defects in the function of beta cells in the islets of Langerhans. Therefore, type 2 diabetes arises under the combined effects of genetic susceptibility and environmental factors, where the patient experiences a decrease in insulin sensitivity that worsens over time, leading to compensatory hyperinsulinemia and impaired insulin secretion. As the condition worsens and progresses, the function of the pancreatic beta cells deteriorates further and becomes inadequate, leading to the onset of type 2 diabetes. Thus, defects in the function of the beta cells are crucial to the development of type 2 diabetes.

What is gestational diabetes like?

Gestational diabetes refers to diabetes that appears during pregnancy, or is detected during pregnancy, or is an abnormal glucose tolerance of any degree. Gestational diabetes affects both the pregnant mother and the fetus. Although the mortality rate of pregnant women with gestational diabetes has significantly decreased, complications are still quite common. It may increase the rate of spontaneous miscarriages and preterm births for fetuses. Secondly, it can cause fetal or neonatal death, and intrauterine growth retardation. Thirdly, it leads to excessive amniotic fluid and macrosomia, and may result in neonatal polycythemia, fetal malformations, neonatal respiratory distress syndrome, neonatal hypoglycemia, as well as neonatal hypocalcemia and hypomagnesemia. For the mother, it can lead to pregnancy-induced hypertension syndrome, infections during pregnancy or childbirth, and in severe cases, diabetic ketoacidosis.

Care of diabetic foot

The care of diabetic foot is very important. In our daily life, we need to do the following aspects. First, regularly wash and check both feet. During washing, the water temperature should not be too high. Also, keep the skin moist to prevent it from drying and cracking. Second, choose suitable shoes and socks, preferably loose-fitting to avoid tightness. Third, be careful when trimming toenails, making sure not to damage the skin of the feet. If there are any sores, go to the hospital immediately for treatment. Fourth, avoid using corrosive chemicals on the feet.

What to eat for diabetic foot

For patients with diabetic foot ulcers, first, their diet should control blood sugar. Foods with a high glycemic index like porridge, glutinous rice, and rice noodle rolls should be avoided. Additionally, sweet foods are also off-limits; it's important for meals to be regular and measured. Second, as patients with diabetic foot ulcers need nutrients for wound healing, they can eat foods high in protein such as eggs, fish, fish soup, and lean meats to promote wound healing. Third, if the patient also has high blood lipids, it's advisable to maintain a light diet and avoid greasy foods.

incidence of gestational diabetes

Gestational diabetes refers to diabetes that appears or is diagnosed during pregnancy, or any degree of glucose tolerance abnormality, which is classified as an independent type of diabetes. Diabetes combined with pregnancy or gestational diabetes can pose serious risks to the health of both mother and child. Before national screening of blood sugar levels during pregnancy was initiated, the detection rate of gestational diabetes was not very high, only 0.24%. However, with the widespread implementation of blood sugar screening during pregnancy, the current incidence rate of gestational diabetes is approximately 1% to 5%.

How to test for diabetes?

The examination for diabetes primarily involves assessment based on symptoms and measuring blood glucose levels through a venous sample. Typical clinical symptoms of diabetes include "three more and one less"; where "three more" refers to dry mouth, increased thirst, and frequent urination, and "one less" refers to weight loss. Thus, generally, when these symptoms are observed, there is an awareness of the possibility of diabetes. Subsequently, one should consult a hospital for further tests, which usually include urine testing and venous blood extraction. For diabetic patients, the glucose level in routine urine tests will significantly increase. Another measure is the direct measurement of blood glucose through venous blood. A fasting blood glucose level of ≥7.0 mmol/L, or a two-hour glucose level of ≥11.1 mmol/L post-OGTT, or a random blood glucose level of ≥11.1 mmol/L, meeting any one of these conditions, combined with the symptoms of diabetes, can diagnose the disease.
