What are the characteristics of diabetic foot?

First of all, there will be particularly serious lesions, and ** is also relatively dry, at the same time** there will also be tingling or numbness, when walking is like walking on cotton, there will also be muscle atrophy.

1. First of all, the hands and feet will feel numb, and there may be a stinging sensation when ants walk. 2. There may be a certain ** temperature drop and a decrease in perception ability, which is very troublesome after it happens.

Diabetic foot is mainly caused by neurological abnormalities and vascular lesions, and the specific clinical symptoms are as follows:

1. Neurological manifestations: numbness, burning pain, ant walking sensation, loss and abnormality of nerve sensation, mainly bilateral symmetry, and some are also unilateral;

2. Vascular manifestations: decreased skin temperature, weakened or disappeared acral arterial pulses, and even avascular necrosis of the lower limbs and gangrene.

Once gangrene develops, it is very tricky and expensive, and in severe cases, amputation is required.

The basic hair elements of diabetic foot are neuropathy, vascular disease, and infection. These factors work together to lead to tissue necrosis, ulcers, and gangrene.

Neuropathy can manifest in a variety of ways, but the most important neuropathy associated with diabetic foot development is peripheral neuropathy with decreased or absent sensation. For example, the foot that feels normal when washing the foot is generally not burned, but the foot with reduced sensation is susceptible to injury. Dryness, dehiscence, and local arteriovenous short-circuits caused by diabetic autonomic neuropathy can also promote or aggravate the development of diabetic foot.

Peripheral arterial disease is another important factor in the development of diabetic foot. Patients with severe peripheral arterial lesions may have the typical symptoms of intermittent claudication, that is, the muscle soreness in the lower limbs is felt after walking for a short distance, the pain is relieved when the pain is stopped and rested, and the muscle soreness in the lower limbs occurs again after continuing to walk for a certain distance. In this way, the patient needs to walk for a while and rest for a while to complete the longer journey.

The shorter the time from the start of walking to the onset of pain, the more severe the arterial lesion of the lower extremities. However, more patients with severe peripheral arterial lesions may develop foot ulcers without this symptom, or the ischemic lesions may become more severe after the insensible foot has been damaged. For patients with severe peripheral arterial disease, foot ulcers are difficult to heal until measures are taken to improve the peripheral blood supply.

Patients with diabetic foot ulcers are susceptible to co-infection. Infection can also be a factor that aggravates diabetic foot ulcers and even leads to amputation. Diabetic foot ulcers are mostly co-infections with gram-positive and negative bacteria, or even with anaerobic bacteria.

Diabetic foot is one of the serious chronic complications of diabetes, and the main causes are as follows:

1. Diabetic peripheral neuropathy, resulting in weakened or absent sensation in the limbs. It reduces the feeling of pressure, foreign bodies, or heat and cold in the feet, so it is easy to cause trauma, scalds and ulcers.

2. Diabetic vascular disease can lead to a decrease in blood flow to the lower limbs, resulting in a lack of oxygen and nutrition in the feet. Therefore, the lower extremities have decreased skin temperature, pain, intermittent claudication, and ischemia. In severe cases, it can lead to ulcers and gangrene.

3. Improper foot care, such as calluses, corns, ingrown nails and chapped nails, etc., and wearing inappropriate shoes and socks makes the pressure of the feet abnormal, resulting in foot injuries.

1. Diabetic neuropathy: when diabetes mellitus is complicated by vascular disease, it is accompanied by peripheral neuropathy and neurovegetative disease, peripheral nerves lead to sensory and motor nerve disorders, muscle atrophy, bone deformation, weakened or disappeared pain and temperature sensation, and infection by trauma or self-injury tissue destruction. Autonomic neuropathy leads to decreased sweating,** dryness, vasomotor dysfunction, ischemia and brittle dehiscence, and infection and necrosis.

The presence of neuropathy often exposes local tissues of the body to danger, and trauma can lead to acral gangrene, diabetic neuropathy and diabetic vasculopathy interact with each other, and interact with each other to aggravate gangrene infection of local tissues. 2. Diabetic foot infection factors: uncontrolled diabetic patients have weakened body defense mechanisms, and the response to invading microorganisms has been inhibited at all stages, including the neutralization of chemical toxins, the bactericidal effect of phagocytic cells of white blood cells, serum factors and cellular immunity, etc., which are easy to infect, and once infected, the disease will be aggravated.

Due to neuropathy, acral sensory impairment, injury infection. Diabetic microangiopathy makes local tissues hypoxic, which is conducive to the growth of anaerobic bacteria, changes the oxygen-dependent bactericidal effect of leukocytes, and once infected, platelet adhesion ability is enhanced, fibrin activity is increased, fibrinolytic activity is reduced, microthrombosis is formed and aggravation of local tissue ischemia and necrosis.

The factors of diabetes may be due to psychological factors, and daily diet is also related to a certain extent, the factors caused by diabetes are still related to exercise, and the ** caused by diabetes may also be caused by genetic factors.

The causes of diabetic foot include diabetic peripheral neuropathy, diabetic peripheral vascular disease, previous foot ulcers or amputations, metabolic factors, etc.

There are many predisposing factors for diabetic foot, such as thin shoes, crowded feet, and improper toenail trimming

The main causes of diabetic foot disease include peripheral neuropathy, peripheral vascular disease, limited joint mobility, increased local pressure, and infection.

Diabetic foot can be divided into three types: neurological, ischemic, and neuroischemic, of which neuroischemia is also called mixed. The characteristics of different types of diabetic foot are different, and the neurological type of diabetes is enough to have neuropathy in the foot, and the blood circulation is better, so the patient will feel warm, numb, and dry in the foot, but the pain is not too obvious. Ischemic diabetic foot patients are mainly vascular lesions of the feet, and the nerve function is relatively good, so this kind of patients will show symptoms of cold feet, which can be pale or cyanosis, can be manifested as intermittent claudication, and the pulse of the foot arteries is also significantly weakened, which is more difficult and has a higher amputation rate.

Patients with neuroischemic type have foot neuropathy and vascular lesions at the same time, arterial pulses and foot sensation are reduced, when there is ** damage, it is easy to lead to the occurrence of diabetic foot, and the wound damage is easy to infect, difficult to heal, and the risk of amputation is very high if it is not timely.

The manifestations of diabetic foot are definitely different for different types and severities, and you can search for the early symptoms of diabetic foot to see if it is the same. This kind of problem should be prompted, and the delay will only get worse.

Diabetic foot is multifactorial, diabetic neuropathy, peripheral vascular disease and microcirculation disorder are the main factors, which can exist alone or in combination with other factors, and other factors such as foot structural deformity, abnormal gait, or toenail deformity, trauma and infection are also important triggers for the occurrence of diabetic foot.

Diabetic vasculopathy and neuropathy are the basic causes of diabetic foot complications, diabetic people's feet are particularly prone to vascular and neuropathy, diabetic vasculopathy and neuropathy affect each other and cause a series of clinical foot diseases, including toe disease, callosum formation, ** damage and foot ulcers, musculoskeletal lesions lead to foot deformation. Diabetics are susceptible to trauma due to neuropathy, which often leads to loss or reduction of the foot, and minor injuries can quickly lead to ulcers, infections and gangrene, which eventually have to be amputated.

Diabetic foot is one of the most serious chronic complications of diabetic patients and one of the leading causes of amputation in diabetic patients. Its basic ** is caused by the chronic complications of diabetes, in the chronic complications of diabetic peripheral neuropathy, diabetic vasculopathy including macrovascular disease and microangiopathy are the basic causes of diabetic foot, plus the local infection of the foot, ulceration and ulceration. The common causes of infection are corns, athlete's foot, and foot injuries when cutting toenails, as well as the above-mentioned chronic diseases, which can easily lead to the occurrence of diabetic foot.

When diabetic foot occurs, the infection rapidly spreads deep and deep, involving muscle tendons. When diabetic foot occurs, you should go to the hospital for diagnosis and treatment in time, control blood sugar, debridement and dressing change, and comprehensive antibiotic treatment, so that the diabetic foot can develop in a better direction.

1. Genetic factors.

Usually a considerable number of diabetic patients are almost caused by genetic factors, especially those with a family history of diabetes. If both husband and wife are diabetic, there is a half chance that their child will develop diabetes. If one of the parents has diabetes, although the child will not necessarily get diabetes, but will become a carrier of the diabetes gene, then the prevalence of the child born to him will be relatively large.

2. Bad living habits and other factors.

In addition to genetic factors, the causes of diabetes are caused by the patient's usual bad habits and some other life factors. For example, overwork when you are young, resulting in impaired function, or congenital deficiency and acquired imbalance, or premature aging, and obese people, etc., have excessive fat accumulation in the body, which interferes with the heart, kidneys, lungs, liver and blood vessel disorders. These factors lead to pancreatic failure and insufficient insulin secretion, which can lead to the chance of developing diabetes.

Long-term hyperglycemia leads to peripheral neuropathy and lower limb arteriosclerosis causes ischemia and hypoxia, resulting in ischemia and necrosis of muscle and nerve tissue, and diabetic foot is caused by non-healing.

1. Caused.

Peripheral nerves. Chronic peripheral vascular complications in patients with lesional diabetes, this peripheral vascular complication will have a series of clinical manifestations in the early stage, due to the gradual narrowing of the lumen of the blood vessels, a series of clinical manifestations, including numbness, pain, and shorter walking distance of the patient's lower limbs, which we call it.

Intermittent claudication.

Or the patient feels pain, even when sitting still, it is also painful, these are complications of the peripheral blood vessels of diabetic patients.

Early detection of neuropathy is mainly to see if there are symptoms such as pain, numbness, dryness, and tingling. Can be made.

Nylon filament feels checked and.

Electrophysiology studies.

Do the median nerve.

Phalangeal nerve, anterior tibial nerve).

2. Vascular lesions of the lower limbs caused by diabetes.

Chronic peripheral neuropathic complications in diabetic patients, especially sensory complications in diabetic patients, are sensory loss or abnormalities in diabetic patients. For example, numbness in paresthesia at the end of the limbs, especially in the feet, walking as if stepping on cotton, or pins and needles are all peripheral nerve complications in diabetic patients.

If the dorsalis pedis artery.

If the pulsation is weakened or absent (of course, the usual method is to compare the two feet), then he may have a foot lesion caused by diabetes, and he should have a foot color.

B-ultrasound examination. Doppler test.

The diagnosis is made if there is a blockage in the major blood vessels mentioned above and a large plaque has formed.

Diabetic foot. 3. Infection.

On the basis of peripheral vascular and nerve complications, due to weak protective measures, due to inappropriate shoes, socks, nail clipping, etc., there is a breakage, then this series of problems are called diabetic foot.

The early symptoms of diabetic foot mainly include: the patient's foot touch, pain, temperature sensation and other perceptions are gradually weakened, and the foot is itchy, desquamated, cracked, tingling, and cold in the lower limbs.

Diabetic foot is a general term for foot pain, ulcers and gangrene of the lower extremities caused by diabetes, diabetic foot is one of the most serious complications of diabetes, most patients will have foot ulcers or gangrene, severe amputation and even life-threatening. Once the symptoms of diabetic foot are detected, the best way to do this is to go to the hospital as soon as possible to prevent the disease from spreading.

1. Pain. Diabetic foot can cause foot pain that may interfere with daily walking, such as walking for a while, the foot will be very painful and you need to rest for a while before walking.

2. The perception of the feet becomes weaker. Many diabetic patients will feel that their foot perception is weakened, and they cannot detect the wound in time, and the perception of pain temperature will gradually decrease, and they will not feel it when their feet are hot.

3. Abnormal. Diabetic foot patients will find that their feet often have abnormal conditions, such as **, roughness, itching, peeling and other symptoms, at this time it is caused by diabetic foot, and they should go to the hospital for foot examination in time.

4. Wounds on the feet are difficult to heal. Diabetic foot patients often have more difficult to heal when they have foot wounds, are prone to ulceration, and always recur because of the poor blood circulation in the lower limbs of diabetic people.

5. Deformity of foot joints. For diabetic patients, diabetic foot also has a typical feature of the foot joint deformity, mainly because when the blood sugar level in the human body continues to rise, the body's metabolism will be impaired, which will affect the body's blood circulation, and the long-term obstruction of blood flow in the joints of the feet will cause joint deformation and deformity.

For diabetic patients, diabetic foot is a very serious complication, and is not conducive to control and **, when diabetic patients begin to have the above symptoms, we must be vigilant, do a good job in the control and prevention of diabetic foot in a timely manner, and pay attention to foot hygiene to prevent fungal infection and ulceration.
