When encountering itchy skin, rashes, long bubbles, etc., many people will take it for granted that "it doesn't matter, it will be fine after a while." ”
One truth is: the skin is a mirror of the health of the whole body, and the appearance of itching, rashes and other signals may be that the body is reminding you that blood sugar is out of control.

High blood sugar can cause various conditions on the skin
Healthy people can control fasting blood sugar below 6.1 mmol/L through the neuroendocrine system. Once the blood sugar exceeds the standard, the glycogen content of the skin tissue increases, which will stimulate the skin to cause various problems.
1
Itching
Elevated blood sugar stimulates peripheral nerves in the skin, which can cause itchy skin. In addition, high blood sugar can also damage the autonomic nerves, making the skin abnormally dry due to reduced sweating.
2
Darkening of the folds of the skin
Velvety pigmentation appears in the folds of the skin, most commonly on the neck, armpits, and groin.
This change is often a sign of prediabetes and may be the first warning sign of diabetes.
3
Skin tags
Stimulated by high blood sugar and insulin, keratinocytes proliferate excessively, and skin tags form.
Skin tags often appear on the neck, armpits, eyelids and other parts, and a thin "pedicle" grows on the skin tags, with a "meat ball" hanging on it, most of which are not uncomfortable, and can be removed by laser if you feel that it affects the beauty.
4
Spots on the front of the calves
It is characterized by a well-circumscribed brown patch on the front of the calf, and is usually a painless, small, flat, well-circumscribed dark red rash at first.
5
Blisters appear
Blood sugar is out of control, and scald-like blisters may appear on the hands, feet, legs, and other areas. The outer wall of the blister is thin, contains serous, there is no red halo around, it can heal itself within 2~6 weeks, and there is pigmentation on the skin after subsiding.
6
infect
Hyperglycemia can inhibit the adhesion and phagocytosis of white blood cells, thereby reducing the body's resistance. At the same time, high blood sugar also favors bacterial reproduction.
The skin may appear red, swollen or rashed, and sometimes small blisters, dry scales, or produce a white discharge that looks like cheese.
7
Annular papules
It is more common on the dorsum of the foot, hands, and joints, and presents as smooth papules and plaques, usually without discomfort.
In the above situation, do not simply think that it is just a skin problem, it is best to check blood sugar, it is likely that blood sugar has exceeded the standard but do not know it; If you already have diabetes, you can talk to your doctor about treatment options to control your condition.
If the blood sugar is high, there is a chance to reverse it
There are 141 million diabetics on the mainland. That's equivalent to 1 in 10 adults around us, there are 1 diabetics.
There are more than 100 complications of diabetes, and when left unchecked, organs and tissues are like soaking in high concentrations of sugar water.
When someone gets the medical examination report, they may be happy: although the blood sugar is above the normal value, it is not diagnosed with diabetes, which means that I am healthy. At this time, these people are already in prediabetes (prediabetes), just one step away from diabetes. The Global Diabetes Map shows that there are nearly 200 million people with prediabetes on the mainland.
If the blood sugar is high, there is a chance to reverse it. The best time to reverse it is "prediabetes" or "when diabetes has just been diagnosed".
Life interventions in pre-sugar can bypass diabetes in half of the population; The other half of the population, even if they develop diabetes, can reduce cardiovascular events by about 30%.
When diabetes is first diagnosed, the toxic effect of hyperglycemia is not long, and after timely removal of toxicity, the function of existing islet cells may return to normal.
Sugar friends who meet the three conditions of overweight, high C-peptide level and no antibody within 5 years of the course of the disease also have a great chance of reversal, with a reversal rate of about 70%.
A good lifestyle is a good antidote for lowering blood sugar
Overall, dietary interventions and exercise interventions are important reversal tools as well as important prevention tools.
1
Breakfast is served no later than 8:30
Medical studies have shown that eating breakfast before 8:30 is associated with lower blood sugar levels and insulin resistance. Breakfast should have more than 2 kinds of meat, eggs, milk, beans, nuts, vegetables, and fruits, and should not eat only staple foods.
2
Reduce carb water to 30%~50%
For people with excessive blood sugar, the amount of staple food can be reduced to 30%~50% of the total amount of food, of which coarse grains account for half of the staple food. Replace the main consumption of vegetables, meat, eggs, milk, nuts.
3
Adjust the order of meals
The meal order of "fiber→ protein/fat →carb" is more friendly to postprandial blood sugar.
4
Slowly
The slower you eat, the easier it is to feel full, and the slower your sugar rises. A meal should preferably not be less than 20 minutes.
5
More coarse and less fine
The finer and softer the food, the faster the sugar rises; And those foods that are not soft enough and need to be chewed carefully are more conducive to stabilizing blood sugar.
6
Cooking is simpler
The simpler the cooking method, the slower the sugar rises, for example, the GI of ready-to-eat oats is 83, and the GI of oatmeal that traditionally needs to be cooked by yourself is only 59.
7
Have dinner early
Research published in the American journal "Nutrients" shows that eating dinner early, recommended around 18:00, can improve blood sugar levels for 24 hours.
8
Adjust your diet
Dietary structures that reduce the risk of type 2 diabetes include the Mediterranean diet, DASH diet, semi-vegetarian and vegan diets, etc.
9
Turn exercise into a habit
Exercise can not only lower blood sugar, but also improve the body's response to insulin, and a combination of aerobic and resistance exercise is recommended.
10
drug therapy
For people with type 2 diabetes and impaired glucose tolerance, acarbose can delay gastric emptying, reduce the overstimulation of glucose to insulin, increase satiety, and relieve hunger after meals. ▲
