Causes of hand numbness, common causes of hand numbness

1. Nerve entrapment can cause hand numbness: 1. Numbness and pain in the thumb, index and middle finger, often with a history of awakening at night, which is caused by the compression of the median nerve in the wrist, and the activity can be improved after waking up. In severe cases, it may be accompanied by atrophy of hand muscles, affecting the fine movements of the hand; 2. Numbness and pain of ring and little finger, and nocturnal numbness and awakening history are caused by nerve entrapment in the elbow, and in severe cases, muscle atrophy is accompanied by decreased flexion of the ring and little finger, which affects fine motor skills.

2. The most common disease that causes hand numbness is cervical spondylosis. In addition to numbness and paresthesia in the fingers, cervical spondylosis is often accompanied by symptoms such as neck and shoulder muscle pain, radiating pain in the upper limbs, or mobility disorders.

3. Another common disease that causes numbness in the hands is stroke. If symptoms such as headache, dizziness, lightheadedness, numbness of limbs, and swollen tongue often occur, and patients usually have hypertension, hyperlipidemia, diabetes, cerebral arteriosclerosis and other diseases, they should pay more attention and be alert to the occurrence of stroke.

4. Menopausal syndrome can also cause hand numbness symptoms: hand numbness is not obvious, the location often changes, not fixed, with the end of menopause, hand numbness will disappear.

First of all, people with early diabetes are prone to hunger and overeating. Early symptoms of diabetes show that because the sugar in the body is excreted as urine sugar, it cannot absorb enough calories to maintain the basic needs of the body, and it will often feel abnormal hunger, and the amount of food will increase greatly, but it is still hungry.

Secondly, early diabetes symptoms can cause eye strain and vision loss. Symptoms of advanced diabetes, early diabetic patients have easy eye fatigue, difficulty seeing, blackening of the eyelids when standing up, narrowing of the field of vision, blurred vision, sudden change of eyes from farsightedness to myopia, or presbyopia that was not present before.

Eventually, early diabetics may have numbness and trembling in their hands and feet. Diabetic patients will have intractable paralysis of the hands and feet, trembling of the hands and feet, ineffective finger movement and labor pain, severe neuritlamic foot pain, paralysis of the lower limbs, low back pain, do not want to walk, calf cramps at night, oculomotor nerve paralysis, attention and eyes are not clear, as well as autonomic nervous disorders and other symptoms, once found, they should go to the hospital for examination without delay.

If the blood supply is insufficient, you should exercise more and not take one position for too long.

This numbness in the hands really needs our attention, in addition to the possibility of stroke, but also because of cervical spondylosis.

What's wrong with frequent numbness? It is roughly related to 4 situations, and you may wish to compare it with self-testing.

We often hear that someone goes to the hospital to see a doctor and diagnose cervical spondylosis because of hand numbness, in fact, there are many reasons for hand numbness, not only cervical spondylosis has this symptom, let's take a look at the common causes of hand numbness.

1. Vascular factors:

When we sit for a long time or sit in a bad posture, it will cause numbness in the lower limbs, and when the posture of the hand is not right, it will also be numb, and when we relax, it will be like thousands of ants crawling. Because when the blood vessels are compressed, the blood vessels ** limbs are partially ischemia, causing numbness, and when the compression is relieved, the blood flows over, and it feels like there are many ants crawling. When the ulnar artery and radial artery of the upper limb are compressed at one point, it will cause numbness in the hand.

2. Neurological factors:

There is axoplasmic flow in the nerve, and when the nerve is compressed, the axoplasmic flow is obstructed, which can also cause numbness in the hands. To the palm, there are mainly radial nerves, ulnar nerves, median nerves, these nerves start from the cervical spinal canal, through the joints, ligaments, bone fiber canals to the end of the palm, in any part, the nerve is compressed, will cause numbness.

3. Brain factors:

All nerves are located in the brain, and when there is a problem in the brain, such as a stroke, the innervated area of the brain will be numb and weak.

4. Systemic factors:

Some full-body'Diseases such as: a. High blood lipids, long-term high blood lipids, easy to cause hardening of blood vessel walls, plus high blood lipids, blood viscosity, blood flow slows down, and cells get less oxygen nutrients, resulting in numbness. b. Diabetics:

Blood sugar is maintained at a high level, and in the long run, it will cause great damage to the body's blood vessels and nerves, arteriosclerosis, and nerve degeneration.

The cervical nerve has an intervertebral foramen that comes out and is divided into two branches: the anterior branch, which goes to the lower lateral side and goes all the way to the forearm, forming the ulnar nerve, radial nerve, median nerve, etc. Posterior Branch:

The muscles that go around the posterior joint of the cervical spine to the back and distribute in the back of the cervical spine can cause numbness in the hands regardless of the compression of the anterior or posterior branches.

Hand numbness, many people must have encountered it, and everyone thinks it is a normal phenomenon. I didn't pay much attention to it, thinking that my hand wouldn't be numb after a while. Even so, hand numbness should not be careless, because regular hand numbness may also hide diseases!

Always be vigilant! Let's take a look at what causes numbness in the hands.

1. Peripheral neuritis causes numbness in the hands

If the elderly have poor digestion and absorption function for a long time and are malnourished, it will cause vitamin B1 deficiency and peripheral neuritis and numbness in the fingers. If the posture is not correct during sleep, the neck is deviated and the arm is compressed, which can also cause numbness in the fingers.

2. Transient ischemic attack causes hand numbness

Elderly people often suffer from hypertension and hyperlipidemia. High blood pressure can cause vasospasm, high blood lipids can cause increased blood viscosity, and slow blood flow during sleep at night can all lead to transient cerebral ischemia and numbness in the fingers.

3. Hand numbness caused by cervical spondylosis

The symptoms of cervical spondylosis are varied, and numbness in the fingers is one of them, and an X-ray of the cervical spine can help diagnose it. **In addition to physiotherapy, traction and the application of some drugs to promote blood circulation and remove blood stasis, cervical spondylosis can usually do some health exercises that move the neck slowly; When sleeping, the pillow should be of appropriate height, soft and hard, and the sleeping position should be correct to avoid compression of local blood vessels and nerve tissues.

Fourth, diabetes can also cause hand numbness

Diabetic neuropathy is one of the many complications that can cause diabetes, and if peripheral neuropathy occurs, symptoms such as numbness and paresthesias in the limbs can occur. Once you have diabetes, you should take a regular and reasonable **, control your blood sugar to a normal range, and pay attention to vitamin B1, vitamin B6, vitamin C, etc.

5. Chronic alcoholism can cause hand numbness

For some people who drink regularly, if numbness in the palms of the hands occurs, it is a sign of chronic alcoholism. Chronic alcoholism, if left untreated, can lead to dysfunction of various systems of the body, even irreversible'Pathological lesions such as chronic gastroenteritis and ulcers, alcohol-toxic myocarditis, fatty liver or cirrhosis, degeneration of the central nervous system, or cerebral atrophy.

6. Stroke

Another common condition that causes numbness in the hands is stroke. "Hygiene Treasure: Stroke Gate" once said: "Mortals who feel that the big finger and the second finger are insensitive or do not use it for the first time will have a stroke within three years."

It must be prevented: it is advisable to live cautiously, eat sparingly, stay away, and be ambitious. Although numbness of the fingers does not necessarily cause stroke, for middle-aged people over the age of 40, if they often have symptoms such as headache, dizziness, lightheadedness, numbness of limbs, and swollen tongue, and the patient usually has hypertension, hyperlipidemia, diabetes, cerebral arteriosclerosis and other diseases, they should pay more attention and be alert to the occurrence of stroke.

What's wrong with frequent numbness? It is roughly related to 4 situations, and you may wish to compare it with self-testing.

Be careful with frequent hand numbness, it may be that there are these 3 kinds of problems on the body, and they should be adjusted in time.

Do you usually have numb hands? It means that I usually don't drink much, and there is no possibility of alcohol overdose poisoning.

The blood flow is not smooth, and it is a precursor to blood clots.

It is usually pressure that prevents blood flow.

The most common causes of hand numbness are as follows:

Upper limb nerve entrapment: a numbness and pain in the thumb, sensitive appetite and middle finger, often with a history of awakening at night, and the activity can improve after waking up. In severe cases, it can be accompanied by atrophy of hand muscles, which affects the fine motor skills of the hand, because the median nerve is compressed in the wrist, which is the so-called "carpal tunnel syndrome"; The second is the numbness and pain of the ring and little finger, and there can also be a history of nocturnal numbness awakening, and in severe cases, it is accompanied by muscle atrophy, and the flexion force of the ring and little finger decreases, affecting fine movements.

This is because the nerve is entrapped in the elbow, the so-called "cubital tunnel syndrome".

This hand numbness、It really needs to be the first of us to pay attention to the cavity.、In addition to the pure pei shirt may be because of stroke、It may also be because of cervical spondylosis。

Generally, if it is not caused by trauma or pressure on the elbow, it is likely to be a problem with the cervical spine.

How do you dig up the history by hand? It is roughly related to 4 situations, and you may wish to self-test against the deficit.
