Diabetes is a disease caused by elevated blood sugar levels, leading to metabolic disorders of proteins and fats within the body.

Early-stage diabetes patients sometimes show no symptoms, while others may experience symptoms such as thirst, frequent drinking, frequent urination, increased appetite, and weight loss. This weight loss manifests as a general decrease in body weight; depending on individual constitution, some may lose 5 kilograms in a month, others may lose 10 kilograms, and in severe cases, some may lose up to 20 kilograms. This is a uniform weight decrease across the whole body, not just slimming of the arms or exclusively losing weight in other specific parts of the body, or just the face.

Therefore, in addition to weight loss, patients may also suffer from fatigue, hunger, and dizziness. It is crucial to promptly test their blood sugar levels, diagnose diabetes as early as possible, and prevent the occurrence of chronic complications.

Is there a difference between gestational diabetes and regular diabetes?

Gestational diabetes and common diabetes, although both types of diabetes, have significant differences between them. First, gestational diabetes is a disease specifically occurring during pregnancy and often only appears during the gestational period. After pregnancy, the majority of women will revert to a normal blood sugar state, so the main focus for gestational diabetes is on screening and intervention during pregnancy; Second, common diabetes is a chronic disease that accompanies an individual throughout their life, requiring long-term management of blood sugar through various methods. Therefore, the main difference between the two lies in the duration of the disease. Pregnant women with common diabetes, if they become pregnant, are referred to as having diabetes compounded by pregnancy, which also requires strict blood sugar management, but its mechanism of occurrence and principles of treatment differ from those of gestational diabetes.

How to Control Gestational Diabetes

During pregnancy, if the pregnant woman has diabetes, it is essential to control blood sugar reasonably. Otherwise, high blood sugar can seriously affect both the fetus and the pregnant woman, and in severe cases, it can cause diabetic ketoacidosis in the pregnant woman and fetal death in utero. Diabetes in pregnant women can be intervened in the following ways: First, through dietary control, eat less sugary foods, such as sweets, pastries, and fruits. Second, it is necessary to be moderately active during pregnancy, taking a walk or maintaining 5,000 to 10,000 steps daily, which helps in the consumption of glucose in the body. Third, if the above two methods are ineffective, insulin should be used to control diabetes.

Gestational diabetes symptoms

During pregnancy, there are two scenarios concerning diabetes: one is where diabetes is diagnosed before pregnancy, referred to as pregestational diabetes combined with pregnancy. The other scenario is where the sugar metabolism is normal before pregnancy, or there is an underlying reduced glucose tolerance, and diabetes appears or is diagnosed during pregnancy, also known as gestational diabetes. Over 80% of diabetic pregnant women have gestational diabetes. Typically, gestational diabetes doesn't show clear symptoms of the classic "three polys and one less" - excessive drinking, eating, urination, and weight loss. Some women with gestational diabetes may experience itching of the vulva, caused by repeated infections with Candida albicans. Additionally, gestational diabetes may lead to conditions like fetal macrosomia and polyhydramnios during pregnancy, and pregnant women with gestational diabetes are more prone to infections.

Diabetes dietary taboo fruits

Many patients have a misconception after being diagnosed with diabetes; they think that fruits are sweet and they should avoid all fruits. This statement is half right—fruits are indeed sweet, but not all fruits are off-limits. Diabetes patients can still consume fruits, provided that they pay attention to the quantity and type of fruit they eat. First, let’s discuss the fruits that should not be eaten by diabetic patients, which are those high in simple sugars. Consuming these fruits can cause a rapid spike in blood sugar levels. Examples include dates, whether dry or fresh, longans, whether dry or fresh, lychees, whether dry or fresh, and bananas, which all have very high sugar content. These fruits are not recommended for diabetic patients; on the other hand, fruits like kiwis, cherries, kumquats, and grapefruits are generally suggested as suitable for diabetic patients.

Causes of Gestational Diabetes

Gestational diabetes refers to the abnormality of blood sugar levels that occurs during pregnancy, at which time it is called gestational diabetes. The reason for the occurrence of gestational diabetes is due to significant changes in the body's endocrine hormones after pregnancy. The body releases many hormones, such as estrogen and progesterone, which can increase insulin resistance. Thus, a much greater amount of insulin is needed to maintain normal blood sugar levels. If the pancreatic beta cells are not sufficient to compensate for the increased insulin secretion needed to meet the normal metabolic requirements caused by these resistance factors, then elevated blood sugar and abnormal glucose metabolism occur, ultimately leading to gestational diabetes.
