High blood sugar not only has the symptoms of “three more and one less”, but also brings a series of changes. Many, many complications of diabetes do not appear quietly, but there are certain signs.
If a person with diabetes has a darkening of the body, be alert to whether the blood sugar has been out of control.
1 The neck turns black
A darkening of the neck in diabetic patients, often seen in obese patients, is called acanthosis nigricans. Acanthosis nigricans is a skin marker of insulin resistance. High concentrations of insulin bind to insulin-like growth factor receptors on the skin’s spinous cells and fibroblasts, which can stimulate the skin’s spinous cells and fibroblasts to overgrow, thickening and darkening the skin on the neck.
It is important to note that acanthosis nigricans causes skin changes that can precede the onset of diabetes long before. Once this kind of problem is found, it is necessary to go to the hospital for consultation and diagnosis as soon as possible, and seize the important opportunity of “reversal” of prediabetes.
2 feet black
If a sugar friend has black feet, there are generally two situations.
The first case is the gradual darkening, which may be caused by the gradual obstruction of blood supply, which belongs to dry gangrene, often without concurrent infection. If the pain is severe, use painkillers, both traditional Chinese medicine and Western medicine.
The second case is sudden blackening. In this case, there is usually pus under the blackening, and it is prone to serious infection within a few days, which belongs to wet gangrene. Wet gangrene must be dealt with quickly when it occurs, it has a very high chance of infection, and surgery should be performed if necessary. Of course, in addition to dealing with black feet in time, it is also necessary to control blood sugar, nutritional status, blood pressure, etc., to maintain a stable state of the whole body and prevent life-threatening.
3 fingers black
If a diabetic patient has darkened fingers or blackened nails, this may be caused by diabetic peripheral nerve lesions and microvascular lesions. In general, continue to strictly control blood sugar, and get in touch with a doctor for treatment if necessary.
4 black tongue
If you find that the tongue is black, especially in the sublingual position, it may be caused by the poor control of blood sugar and blood lipids in diabetics. Pay attention to control blood sugar and blood lipids.
5 darkening of the skin
People with diabetes will also experience dark skin, which may be due to the formation of pigmentation due to blood circulation disorders. Especially in some patients with poor blood sugar control and a long course of diabetes, peripheral vascular lesions often occur, such as the formation of arterial plaques, or even stenosis and poor venous return, and blood circulation will become slow. Pigment in the blood is easily deposited on the skin in large quantities, resulting in darkening and blackening of the skin.
