Many of you have probably heard of it
Blood sugar is high
There will be various discomforts in the body
For example, dry mouth, polyphagia, weight loss, fatigue, etc
But often these symptoms are not noticeable
So a lot of friends
It can't be judged directly
Whether you have diabetes
But luckily
Our body actually has its own "blood glucose meter"
That's our legs and feet
Today
Let's learn together
How to do this by observing the changes in the legs and feet
to prevent and control blood sugar
Why legs and feet can be called
"Walking blood glucose meter"?
When blood sugar is exceeded, blood vessels are often the first to be damaged, especially small ones.
In an environment of persistent high blood sugar, the inner layer of blood vessels is damaged, and glycoprotein deposition causes thickening of the blood vessel walls and affecting blood flow.
Once the blood sugar in the body is constantly rising, it will lead to an increase in blood viscosity and affect blood circulation, and the legs and feet are located at the far end of the body and are more sensitive to changes in blood circulation. When the lumen of the blood vessel becomes smaller, the symptoms of ischemia will become more pronounced, thus releasing a series of warning signs.
In addition, in a hyperglycemic environment, it will accelerate the damage of blood vessels, especially the small blood vessels in the legs and feet, and the damage of these blood vessels will lead to peripheral neuropathy and local tissue ischemia, which can easily cause peripheral nerve inflammation and lead to abnormal symptoms in the feet.
Be wary of these five symptoms!
It may be a warning that your blood sugar is out of control
01 Wounds do not heal easily
High blood sugar can affect wound healing because the wound is not adequately nourished and the skin's ability to repair itself is reduced. If skin lesions do occur, they may not heal. This is because when blood sugar rises, bacteria in the body tend to overgrow, and inflammation is not easy to recover.
Moreover, people with high blood sugar have poor microcirculation, especially cutaneous microcirculation, and capillary embolism reduces local blood flow, and the ability of cells to transport nutrients to tissues is reduced, making it difficult for nutrients to reach the wound and making it difficult for the wound to heal.
02 Itching:
For patients with high blood sugar, bacterial or fungal infections are easy to grow on their skin, and skin infections can also cause itching symptoms in patients.
Skin itching caused by diabetes, usually manifested as persistent itching, is mostly due to dry skin and diabetic peripheral neuropathy, resulting in itchy skin, which looks relatively smooth and has no obvious pigmentation or changes specific to skin diseases such as macules and pimples. Especially in the hands and feet, sometimes accompanied by an "ant walking sensation", the symptoms may be more pronounced at night.
03 "Sugar spots":
Well-defined brown patches appear on the front of the lower legs, which are skin lesions specific to diabetes.
Diabetic patients due to persistent hyperglycemia, resulting in vascular endothelial cell dysfunction and capillary hypertension, coupled with protein metabolism disorders, resulting in insufficient blood flow and malnutrition in the skin, and a slight trauma stimulates the tibia of both lower limbs, sugar plaques can occur.
Sugar spots are more common in male diabetic patients, occurring on the front side of the calf, skin erythema, blisters, purpura, erosion or ulcers can occur at the beginning, and then gradually form a variable number of brown spots of different shapes, which are not painful or itchy, and are specific skin lesions of diabetes.
04 Chapped skin:
If the patient has severe hyperglycemia and high glucose content in the blood, the superficial tissue fluid of the skin may be in a hypertonic state, and the water of epidermal cells will diffuse to the tissue fluid and plasma, dehydrating the epidermal cells, and then causing dry and peeling skin.
In addition, diabetic patients generally have poor peripheral circulation, poor nutrition of nerves and blood vessels, and symptoms such as dryness and chapped skin.
05 Numbness in the legs and feet:
Long-term high blood sugar can damage the nervous system, causing numbness or tingling in the legs and feet, which is a sign of blocked blood circulation.
How to control blood sugar scientifically?
Meals have protein, and low carbon is very important
Protein-rich foods can help lower postprandial blood sugar throughout meals when eaten with staple foods. Therefore, there should be one or two protein-rich foods at every meal.
To manage blood sugar, especially to reduce blood sugar after meals, it is necessary to reduce the intake of refined staple foods and increase the proportion of coarse grains to achieve moderate low-carbon. The normal standard is to consume 250~300 grams of carbohydrates per day, and the moderate low-carbon standard is to consume 120~200 grams of carbohydrates per day, that is, to reduce the amount of staple foods by 40%~50%.
Diet management and treatment are at the heart of glycemic control in people with diabetes. The guidelines suggest that diabetic patients should follow the principle of a balanced diet, so that the food is diverse, the staple food is quantitative, the vegetables, fruits, milk beans are abundant, less oil, less salt, and less sugar, and at the same time, the daily energy is appropriate and the nutrient intake is sufficient.
5 ingredients per meal, change the order of eating
In real life, many diabetics dare not eat this or that, thinking that the simpler and less they eat, the lower their blood sugar will be. This is not the case. Eating two buns alone or eating a bowl of noodles has higher blood sugar after a meal because monotonous food digests quickly and does not carry hunger.
Diabetic patients should not only pay attention to food diversity, but also pay attention to the order of meals, and have a lot of knowledge about what to eat first and what to eat later. The Chinese Nutrition Society's "Dietary Guidelines for Type 2 Diabetes in China" suggests that the order of eating vegetables, meat, and staple foods should be followed to reduce postprandial blood sugar fluctuations, and long-term adherence can also significantly reduce the postprandial blood sugar and glycosylated hemoglobin levels of diabetic patients.
Less sit-quiet, more active
In addition to eating, "moving" is also important for diabetics. Diabetics should try to move their bodies as much as possible after meals and do not sit still. Exercise has many benefits for people with diabetes, including blood sugar control, weight maintenance, improved insulin sensitivity, inflammation control, cardiovascular complications, and mental health.
People with diabetes should be active (exercise) as part of their treatment and stick to it for a long time. About 30 minutes after eating, do low-to-moderate intensity aerobic exercise, such as walking, jogging, cycling, dancing, skipping rope (slow), swimming, aerobics, tai chi, etc. Daily physical activities include climbing stairs, cycling, doing household chores, etc. It should be noted that diabetic patients should not exercise for too long at a time, and should also pay attention to their physical condition during activities (exercise) to avoid hypoglycemia.
