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

Old Liu, 53 years old, his body is still healthy, but his legs are not too neat, 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.

Recently, an ulcer appeared on the fourth toe of the right leg, and it was still black . It has not improved after a week. This made Lao Liu a little scared, so he went to the hospital.

After consultation and palpation, the doctor found that there was vascular occlusion in Lao Liu's right lower extremity. Later, a lower extremity CTA examination was performed to confirm this. The bilateral lower extremity arteriosclerosis was occluded, the right superficial femoral artery was completely occluded, and the sub-knee artery was occluded. .

In the case of Lao Liu, a complication—diabetic foot appeared due to the lack of timely control of diabetes . Fortunately, after standardized treatment, Lao Liu’s condition improved.

1. Every 5 seconds, 1 person dies of diabetes

There is a high incidence of diabetes in China, but many people still do not pay attention. According to relevant data in 2021, there are about 6.7 million adults aged 20 to 79 in the world who die due to diabetes or its complications , which means that every 5 seconds, someone suffers from it. Lost life.

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

That is, the blood sugar level is higher than that of healthy people, but it does not meet the diagnostic criteria for diabetes . It is divided into two situations: one is high fasting blood sugar, blood sugar is between 6.1~7.0mmol/L; the other is fasting and postprandial blood sugar are both high, 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 diabetic symptoms plus random blood sugar value is ≥11.1mmol/L, and the blood glucose value 2 hours after a meal is ≥11.1mmol/L, it is classified as diabetes.

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

After the onset of the disease, if the blood sugar is not controlled in time, it may lead to retinopathy, kidney failure, cardiovascular and cerebrovascular diseases, and eventually disability and death. Therefore, for diabetes, we need to pay enough attention, once found, timely treatment.

2. These 3 abnormalities in the feet may be caused by elevated blood sugar

The most typical symptoms of diabetes are "three more and one less", 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 may not only cause disability, but also have a high mortality rate .

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

1. Joint deformation

If the blood sugar cannot be lowered, the nervous system of the foot may suffer from lesions, the muscles and bones will change, and eventually the joints will deform .

2. The skin of the feet is purple

The blood sugar has been exceeding the standard, which will lead to lesions of the nerves and blood vessels in the feet, which will make the blood circulation worse, the blood flow rate will slow down, and the color of the blood will turn purple through the skin .

3. Intermittent claudication

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

Therefore, if these abnormalities occur in the feet, you should be alert to high blood sugar, especially when the foot wounds persist for a long time or local redness and swelling occur , it is recommended to go to the hospital for a look at a diabetic foot specialist as soon as possible.

3. Rice, noodles and steamed bread, which one is easy to raise blood sugar?

Diabetic patients want to control sugar, how to choose a diet is also a critical step.

As the common staple food of Chinese people, rice, noodles and steamed bread are foods with relatively high sugar content. Many diabetic patients are worried that their blood sugar will rise after meals and dare not eat the staple food. So, which staple food is more likely to raise blood sugar? Let's look at a picture first:

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

• eat miscellaneous

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

• eat slower

When eating, pay attention to control the speed, control a meal in about 20 minutes , do not gobble it, so as to avoid eating too much food in a short time and increase postprandial blood sugar.

• eat lean meat

Diabetic patients should also eat meat in moderation, because moderate intake of fat can delay the rise in blood sugar after meals , but pay attention to the total energy intake must be well controlled, otherwise the energy exceeds the standard 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, which is a good choice. When eating poultry such as chicken, duck, and goose, you should pay attention to peeling.

• eat lightly

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

Summary: Diabetes is not only high-incidence, but also dangerous, 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 inspection in time, and then intervene in a targeted manner, so as to control your blood sugar to a normal level as soon as possible and reduce the risk of diabetes. s damage.
