What causes numb fingers in daily life

Fingers are flexible helpers in our lives, but if numbness occurs in the fingers, do you know what the reason is? Numbness in the fingers may be a sign of illness in the body, so everyone must pay attention to this situation.

Causes of numbness in fingers

1. Gout

There was once a man in his 30s who often felt numbness and pain in his hands after surfing the Internet for less than five minutes. During the medical examination, the doctor found that the patient's big toe and ankle joints were red and swollen. A blood test showed that the uric acid level was as high as 9.2mg/dl (the normal value should be 4 to 7), confirming that the patient had gout. After treatment, the numbness and joint pain in the hands and other problems were improved. Clinically, about 1% of patients with hand numbness suffer from gout, which may be caused by uric acid deposited in the median nerve, compressing the median nerve and causing numbness and pain in the hands.

2. Transient cerebral ischemia

This is a common cause of numbness in the hands of the elderly. The elderly often suffer from high blood pressure and high blood lipids. High blood pressure can cause vascular spasm, and high blood lipids can cause vascular sclerosis. In addition, the blood viscosity of the elderly increases and blood flow is slow during sleep. These factors can lead to transient cerebral ischemia and numbness of the hands.

3. Cervical spondylosis

Cervical spondylosis is a common disease among middle-aged and elderly people. It is caused by compression of local blood vessels and nerve tissues in the cervical spine due to cervical bone hyperplasia, intervertebral disc degeneration or relaxation of local joint ligaments. Its symptoms are varied, and numbness of the hands is one of them.

4. Diabetes

Diabetes can cause many complications, diabetic peripheral neuropathy is one of them. Once this complication occurs, there will be symptoms such as numbness and abnormal sensation in the limbs.

5. Peripheral neuritis

If the digestion and absorption function is poor and malnutrition occurs for a long time, it will cause vitamin B1 deficiency leading to peripheral neuritis and also cause numbness in the hands.

6. Compression of the brachial nerve

If the sleeping posture is incorrect, the neck is tilted or the arms are under pressure, the brachial nerves may be compressed and cause numbness in the hands.

7. Overdose

Overdose of certain drugs, such as gentamicin, can cause side effects such as numbness in the lips and limbs, so be careful to avoid overdose.
