Is swelling of hands a kidney problem?

The kidney is one of the important organs in our body. The kidneys are related to human growth and development and also have metabolic functions. It mainly secretes urine and excretes metabolic waste. Generally, kidney problems will cause local edema in the body. Many friends feel swollen hands when they wake up, or even some friends have swollen legs and feet. Edema generally occurs in middle-aged and elderly people. Some may be caused by fatigue from the previous day. Some are due to kidney problems. So, does feeling swollen in your hands mean there is something wrong with your kidneys? Let’s take a look at it together.

The human body is an organic whole. Disease in any part of the body will affect the entire body. Local disease can cause general discomfort. Some diseases not only plague the body, but also invade people's hands, causing some changes in the color, shape, dynamics or functions of the hands.

Numbness in the fingers is a common symptom. Mild numbness is often ignored. If you often feel numb, are getting old, or suffer from high blood pressure, you should consider that it may be a precursor to a stroke. The characteristic of stroke numbness is that it starts from the ring finger, then develops to the middle finger, and finally involves the whole hand. Some people may first experience numbness in the index finger, which gradually radiates upwards. In severe cases, the numbness may extend to the forearm.

Sometimes the knuckles at the end of the fingers become enlarged like drumsticks, and the nails are curved upward like a parrot's beak, which is medically called "tusker fingers". This could be emphysema, congenital heart disease, or bronchiectasis.

When the forearm is injured, if the median nerve or ulnar nerve is injured, although the hand is not injured, the hand often cannot be straightened and is in a semi-flexed state. If you encounter this situation, you should go to the hospital for surgical correction to prevent future problems.

If you wake up in the morning and your hands are swollen and difficult to flex or extend, the symptoms will gradually improve or disappear soon after you get up. This phenomenon may indicate that you may have problems with your heart, kidneys, liver, or have malnutrition-related edema. If you encounter this situation, you should go to the hospital to find out the cause and treat it. Otherwise, over time it will make you haggard, your skin and hair will become dull, and your overall appearance will be affected.

For alcoholics, if they notice hand tremors, they should consider whether they have chronic alcohol poisoning and should control their drinking or quit drinking. People who do not drink alcohol should consider whether they have hyperthyroidism.
