Gestational diabetes indicators
Gestational diabetes refers to the absence of a diabetes history before pregnancy, but during pregnancy screening (Tang screening), blood sugar abnormalities are discovered. At this point, the diagnosis of gestational diabetes is made. The criteria for diagnosing gestational diabetes are based on a diabetes screening test conducted at 24-28 weeks. If the fasting blood glucose is ≥5.1, one-hour blood glucose is ≥10.0, or two-hour blood glucose is ≥8.5, meeting any one of these criteria is sufficient for a gestational diabetes diagnosis.
Symptoms of gestational diabetes
Gestational diabetes refers to abnormal glucose tolerance that occurs during pregnancy. It usually involves only mild, asymptomatic hyperglycemia without the typical symptoms of diabetes such as dry mouth, excessive thirst, frequent urination, and weight loss. However, significant increases in blood sugar can lead to symptoms such as dry mouth, excessive thirst, frequent urination, and weight loss. It is important to be vigilant for gestational diabetes in patients who exhibit symptoms such as excessive amniotic fluid, a large fetus, or recurrent urinary tract infections. Therefore, it is generally recommended for pregnant patients to complete an OGTT (Oral Glucose Tolerance Test) by the 24th week of pregnancy to confirm whether they have gestational diabetes. After childbirth, blood sugar levels in women with gestational diabetes generally return to normal, but the risk of developing Type 2 diabetes in the future significantly increases. Therefore, patients with gestational diabetes should undergo diabetes screening 6 to 12 weeks postpartum and be monitored over the long term.
Type 2 diabetes daily diet
Type II diabetes requires careful daily dietary considerations. First, meals should be regular and moderate in portion; overeating is to be avoided. Second, ideally consume only three meals a day and avoid late-night snacks, which is a habit that many people have but is inadvisable. Third, the amount of carbohydrates per meal should be controlled; about 100 grams of staple food per meal is sufficient for those who perform moderate physical labor and do not engage in heavy physical activities. Fourth, sweet foods like pastries and cakes, which are high in sugar, should be completely avoided. Fifth, foods like porridge and glutinous rice, which have a high glycemic index, are not recommended. Lastly, very sweet fruits such as lychees, longans, durians, grapes, and bananas are too sugary and not suitable for consumption.
Early symptoms of type 2 diabetes
The typical symptoms of type 2 diabetes are referred to as "three excesses and one deficiency." The three excesses include excessive thirst and dry mouth, increased appetite with frequent hunger, and increased urination. The one deficiency refers to weight loss; these are the more typical symptoms. Some patients might often find out about their elevated blood sugar during routine health checks at work. Others may seek medical advice due to issues like skin itchiness or wounds that heal poorly after injury. Some might mainly experience numbness in their hands and feet, or blurred vision among other symptoms.
How to control diet for diabetes
The diet for diabetes mainly involves setting reasonable blood sugar reduction targets. Before achieving these targets, strict dietary control is necessary. All fruits, nuts, fried foods, and barbecued foods must be avoided. Meals should be regular and quantified without any extra meals or snacks. The amount of rice for lunch and dinner should be controlled, approximately a couple of ounces per meal, while intake of sufficient vegetables is encouraged to satiate hunger. However, vegetables like pumpkin should not be eaten. A certain amount of lean meat can be included, but fatty meats are to be avoided. Additionally, dry foods are recommended for diabetics, while liquid diets, like soups and porridges, should be avoided. For breakfast, if blood sugar control is poor, one should temporarily avoid noodles and rice noodles. Instead, consuming some pure milk and an egg, along with buns or dumplings such as steamed dumplings or wontons, is acceptable.
Symptoms of diabetic foot
Diabetic foot is one of the severe chronic complications of diabetes, generally referred to as the abnormalities in the lower limbs caused by diabetic vascular neuropathy. Diabetic foot with gangrene of the extremity due to concurrent infection is referred to as diabetic foot with gangrene of the extremity, representing a serious stage in the progression of diabetic foot. The main symptoms of diabetic foot include: first, subcutaneous fat atrophy, thinning of the skin, common pigmentation spots on the shin, no hair on the feet and toes, and thickening of the toenails often accompanied by fungal infections; second, atrophy of the extremity muscles, malnutrition, poor muscle tone, and susceptibility to injury in joints and ligaments; third, visible sinking of the finger joints, joint bending, weakening or disappearance of foot deformities, and cool, swollen skin at the extremities; fourth, patients often experience extremity pain, numbness, sensory abnormalities, and dull or absent deep and superficial reflexes. In the initial stages of diabetic foot gangrene, blistering, blood blisters, erosion, and infection can gradually develop into ulcers, gangrene, or necrosis. Clinically, this is manifested as localized redness, swelling, increased skin temperature, pain, functional impairment, and the presence of purulent secretions, sometimes accompanied by a foul odor.
Diabetic foot prevention care
First of all, it's important to keep blood sugar under control. It's recommended that people with diabetes check their glycated hemoglobin every three months to see if their blood sugar levels meet the standards. Second, many patients suffer from diabetic foot due to severe diabetic peripheral neuropathy. Injuries such as stepping on a nail or accidental bumps may lead to infections. Therefore, it's suggested that patients with diabetes check their feet daily for any small wounds or ulcers, and if found, they should seek timely treatment from an endocrinology specialist. Third, using warm water for foot baths and treatments like local infrared lamp therapy are advised. It's important to ensure that the temperature is not too high, generally around 40 degrees Celsius, to avoid burning the skin.
Causes of diabetic foot
The main causes of diabetic foot are as follows: The first one is poor blood sugar control in patients. Some patients have long neglected their blood sugar levels, leading to consistently high levels. The second cause is vascular disease in the lower limbs of the patient, including arteriosclerosis, with severe cases leading to occlusion and subsequent ulceration of the feet. The third reason is the presence of diabetic peripheral neuropathy in patients, which results in abnormal sensations or numbness in the feet. Many patients wearing new shoes or stepping on sharp objects inadvertently can lead to diabetic foot. The fourth cause is infection induced by patients who initially neglect minor foot injuries, or who improperly manage such injuries at home, leading to the development of diabetic foot. Therefore, we advise diabetics to maintain good control of their blood sugar and take timely measures to prevent diabetic foot.
Diabetic foot ulcer precursor
Diabetic foot, as we discuss in medical terms, refers to patients with a history of diabetes who, due to poor blood sugar control, experience various complications such as the narrowing of arteries in the lower limbs, insufficient blood and oxygen supply, and neuropathy, which results in insensitivity to temperature and pain, making them prone to burns or other injuries. Additionally, diabetic patients have compromised immune systems, making them susceptible to infections. When these three factors combine, it easily leads to diabetic foot, which is also the precursor to what is colloquially known as "rotten foot" in diabetes.
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.
