1. Numb and foot pain
Numb and foot pain is a clear warning sign of hyperglycemia. Due to the occasional symptoms of numbness and pain in our feet in our daily life, many patients with hyperglycemia think this is a small problem, and this symptom is too hidden and easily overlooked by us. But if we often experience numbness and pain in our feet, we should pay attention, it may be that our blood sugar is rising.
The reason for this is that when the blood sugar level in the body is too high, it affects the blood vessels and also affects the nervous system. When some patients with high blood sugar develop diabetes, the symptoms of numbness and pain in the feet will be more obvious. The main reason is that the weight of our whole body rests on our feet every day, so the pressure on the feet is high, including the blood vessels.
At the same time, coupled with the influence of diabetes on nerves and blood vessels, neuropathy and vascular disease caused by diabetes have caused diseases in some blood vessels. For example, when a blood vessel is narrowed or blocked, our feet will experience severe pain. Therefore, when we have the above symptoms, we must pay attention to go to the hospital for relevant examinations to avoid the disease becoming more serious due to high blood sugar.
In addition, when our body’s blood sugar levels are too high, our feet will also experience other symptoms. This also provides an effective protective measure for predicting whether our blood sugar level is normal.
2. Discoloration of feet
Discoloration of feet is an important manifestation of human hyperglycemia. Many patients with hyperglycemia will have symptoms of discoloration of the feet. If we have similar symptoms in our daily life, after excluding external interference factors, this may be because the blood sugar level has increased.
When there is high blood sugar, the main manifestation of the feet is that the toes will turn black and purple. The reason for this symptom is that the blood circulation in the feet is blocked. In other words, high blood sugar is one of the primary culprits of poor blood circulation.
High blood sugar can cause vascular disease and neuropathy. To a large extent, high blood sugar will lead to an increase in blood viscosity, which will weaken blood circulation. Then the blood circulation system will be affected. This leads to the symptoms of insufficient blood supply to the feet, and the feet are nerve endings in the blood circulation. Once the blood circulation is not smooth, it will be reflected in the first time, and the main manifestation is the appearance of black and purple.
3. Foot wounds are difficult to heal
If there is a contusion on the foot in daily life, it is easy for normal people to heal of. But for patients with high blood sugar, foot wounds are difficult to heal. Therefore, this symptom should also be paid attention to. It is a more obvious manifestation than the above two symptoms.
There are generally three factors that cause this symptom. The first is the infection factor. The foot wound of patients with high blood sugar is easy to breed bacteria after infection, and it is especially prone to the accumulation of various bacteria. At this time, it is difficult for the wound to heal.
Secondly, it is caused by insufficient blood supply and poor nutrition. Patients with high blood sugar also have nutritional problems, such as poor blood supply or neurotrophy, which will affect wound healing. Because we mentioned above that high blood sugar can lead to lesions leading to diabetes, and diabetic patients will have vascular disease and neuropathy, which will also make foot wounds difficult to heal.
Finally, the factors of the wound on the foot make it difficult for the wound to heal. For patients with high blood sugar, the wound does not heal, but also pay attention to the situation of the wound surface of the foot. The edges of some wound surfaces are relatively dry, or the edges of the wound surface are composed of many calluses, which can also cause the wounds of patients with high blood sugar on the feet to be difficult to heal.
