Elevated blood sugar, can you tell by looking at your feet? These 3 changes in the feet remind you that it is time to reduce blood sugar

Lao Liu, 53 years old, is still in good health, but his legs are not too sharp, and the numbness has lasted for more than 2 years. But Lao Liu was afraid of going to the hospital to spend money, so he endured it all the time.

Recently, an ulcer appeared on the fourth toe of the right leg, and it was still black . It hasn't improved after a week. This made Lao Liu a little scared, so he left for the hospital.

After questioning and palpation, the doctor found that there was vascular occlusion in Lao Liu's right lower extremity, and then performed a CTA examination of the lower extremity, which confirmed this. The bilateral lower extremity arteriosclerosis was occluded, the right superficial femoral artery was completely occluded, and the inferior knee artery was occluded. .

As for Lao Liu's condition, due to his diabetes not being controlled in time, he developed a complication - diabetic foot . Fortunately, after standardized treatment, Lao Liu's condition has improved.

1. One person dies from diabetes every 5 seconds

China has a high incidence of diabetes, but many people still don't pay attention to it. According to relevant data in 2021, there are about 6.7 million adults aged 20 to 79 in the world who die from diabetes or its complications , which means that every 5 seconds someone dies from diabetes lost his life.

At present, at least 300 million to 500 million people in China are pre-diabetic. What does it mean?

That is, the blood sugar level is higher than that of healthy people, but it has not yet reached the diagnostic criteria of diabetes . It can be divided into two situations: one is high fasting blood sugar, the blood sugar is between 6.1-7.0mmol/L; the other is high fasting and postprandial blood sugar, the blood sugar is between 7.8-11.1mmol/L.

At this time, if the blood sugar is not controlled in time, when the fasting blood sugar is ≥7mmol/L, or when the diabetes symptoms plus random blood sugar value is ≥11.1mmol/L, and the 2-hour postprandial blood sugar value is ≥11.1mmol/L, it will be classified as diabetes.

Why does diabetes occur? It is related to heredity, viral infection, bad living and eating habits, and untimely treatment of diseases (such as hypertension, atherosclerosis, hyperlipidemia, etc.).

After the onset, if the blood sugar is not controlled in time, it may cause retinopathy, kidney failure, cardiovascular and cerebrovascular diseases and other multi-organ diseases, and eventually become disabled and dead. Therefore, for diabetes, we need to pay enough attention to it, and treat it in time once it is discovered.

2. These 3 abnormalities in the feet may be due to elevated blood sugar

The most typical symptoms of diabetes are "three excesses and one deficiency", which are polydipsia, polyuria, polyphagia and weight loss .

If not intervened as soon as possible, it can cause various complications such as diabetic eye disease, diabetic neuropathy, diabetic nephropathy, diabetic foot, and erectile dysfunction. Diabetic foot, in particular, is a very serious complication, which not only may cause disability, but also has a high mortality rate .

Therefore, when the following 3 abnormalities appear on the feet, you need to be vigilant.

1. Joint deformation

If the blood sugar does not drop all the time, the nervous system of the foot may suffer from pathological changes, the muscles and bones will change, and eventually the joints will deform .

2. Purple skin on feet

Excessive blood sugar will cause the nerves and blood vessels of the feet to suffer from pathological changes, which will make the blood circulation worse, the blood flow speed will slow down, and the color of the blood will turn purple when it passes through the skin .

3. Intermittent claudication

This is a typical manifestation of diabetes, mainly due to the failure of blood vessels in the feet, resulting in insufficient blood supply to the lower limbs, which affects walking and intermittent claudication.

Therefore, if these abnormalities appear on the feet, one must be alert to high blood sugar, especially when the foot wounds are not healed for a long time or local redness and swelling appear , it is recommended to go to the hospital for a diabetic foot specialist as soon as possible.

3. Rice, noodles or steamed buns, which one is easier to raise blood sugar?

If diabetics want to control their sugar, how to choose a diet is also a critical step.

As a common staple food for Chinese people, rice, noodles and steamed buns are foods with relatively high sugar content. Many diabetics are afraid to eat staple food because they are worried that their blood sugar will rise after a meal. So, which staple food is more likely to raise blood sugar? Let's look at a picture first:

Picture Medical Endocrinology Channel

It can be seen from the figure that if we only look at the ingredients, the glycemic index (GL value) of noodles is the lowest . But the type of ingredients and different cooking methods will also affect the GL value, so if you want to control sugar better, you can't just look at their glycemic index. How to eat the staple food of diabetic patients?

• Eat a little more

Don't just eat the staple food, you can properly mix some miscellaneous grains in the staple food , such as black rice, purple rice, oats, etc., which contain low carbohydrate and starch content, which can help reduce postprandial blood sugar.

• eat slowly

When eating, pay attention to controlling the speed, keep a meal to about 20 minutes , and don't gobble it up, so as to avoid the increase of postprandial blood sugar due to excessive food intake in a short period of time.

• eat lean meat

Diabetics should also eat meat in moderation, because moderate intake of fat can delay the rise in blood sugar after meals , but attention must be paid to controlling the total energy intake, otherwise energy excess and weight gain will reduce the body's sensitivity to insulin, which is not conducive to Blood sugar control.

Therefore, it is recommended to focus on lean meat, especially fish is a good choice. When eating chicken, duck, goose and other poultry meat, pay attention to peeling.

• eat lightly

In order to prevent diabetic complications, we should not only pay attention to blood sugar control, but also pay attention to blood pressure and blood lipids, because many diabetic complications are related to high blood pressure and high blood lipids, so the usual diet should be as light as possible, with less oil (<25-30g/day) Less salt (<5g/day) .

Summary: Diabetes is not only a high incidence, but also very harmful, so we must pay attention to its prevention. Once you suspect that your blood sugar is too high, you should go to the hospital for examination in time, and then intervene in a targeted manner to try to control your blood sugar at a normal level as soon as possible and reduce the risk of diabetes. s damage.
