"People say that the hand is a magnifying glass for cerebral infarction, is this true?" As soon as Uncle Xie Ruizhang said this, the onlookers put down the chess pieces in their hands and stared at his hands.
This retired veteran worker has become a habit of playing chess in the park, but recently when he heard this, he panicked a little. His right hand is occasionally a little numb, and he is not as dexterous as he used to be in holding chess pieces. The next day, Uncle Xie went to the hospital with a patronage, thinking that he wanted to see Dr. Peng.
In the consultation room, Dr. Peng listened to Uncle Xie's description, and then began a detailed examination. After the examination, Dr. Peng sat down and patiently explained to Uncle Xie: "Uncle Xie, there is actually a certain basis for this statement you heard. It is true that the hand can reflect some neurological problems, but not all hand problems are directly related to cerebral infarction. ”
He went on to explain in detail the basics of the nervous system, explaining why some specific symptoms of the hand may be 'sentinels' of brain diseases. For example, numbness or weakness in the hands may be caused by a problem with the brain or cervical spine caused by a local poor blood flow. Dr Pang also stressed that these symptoms are not absolute and need to be confirmed with more tests.
"So, if you feel persistent numbness, weakness or a sudden abnormality in your hand, it's best to come to the hospital for a full check-up." Dr. Peng's explanation was both professional and easy to understand, which made Uncle Xie listen to it with relish, and the stone in his heart finally fell to the ground.
In modern medicine, hands are often seen as a "barometer" of health. It is not only a tool for our daily activities, but also a reflex area for various disease signals.
Changes in the color of the hands. You may notice that sometimes your fingers become unusually pale and even more noticeable in cold environments. This condition is usually related to blood circulation and can be a sign of Raynaud's phenomenon.
Raynaud's phenomenon is a type of vascular dysfunction in which the blood vessels in your hands constrict abnormally when you are in a stressful or low-temperature environment, resulting in reduced blood flow and whitening of your fingers. And it's not just a matter of cold, in the long run, if it occurs frequently, it may indicate a more serious systemic disease, such as scleroderma or rheumatoid arthritis.
Swelling of the fingers. It's not uncommon to hear complaints of stiff, swollen fingers after waking up, which may be related to a slowdown in fluid circulation at night, but if this condition persists, it's not a trivial matter. May be an early manifestation of rheumatoid arthritis. In addition, hyperthyroidism or hypofunction can also cause swelling of the hands, which is often accompanied by symptoms such as weight changes and abnormal heart rate.
Fingernails, nails can also reflect health. For example, spoon-shaped dimples in the nails may be a sign of iron deficiency anemia. If the nail appears bumpy or has transverse grooves, this may indicate chronic kidney disease. The kidneys are not fully functioning and are unable to effectively remove toxins from the body, which can affect the growth of the nails, resulting in abnormal nail appearance.
The feeling of the hand is also crucial. Many people may have experienced numbness in the hands, which may be related to sitting or sleeping in part, but if the numbness is prolonged or frequent, especially if it is accompanied by a tingling sensation, then there is a need for alarm.
This can be a sign of peripheral neuropathy, such as diabetic neuropathy, in which high blood sugar damages peripheral nerves due to poor blood sugar control, resulting in paresthesias in the hands.
The hands are not only a tool for our daily activities, but also an open medical reference book with clues about our health.
Therefore, when you have any of the above abnormalities in your hands, do not turn a blind eye and seek medical attention as soon as possible for professional examination and treatment. In this way, we can not only detect diseases in time, but also have better control over our own health.
