What is the reason for swollen hands

Many people accidentally find that their hands are swollen, and there is no pain, which makes people very distressed. What causes the swelling of the hands? Unexplained swelling of the hands is still worrying, but the decision to seek medical attention depends on the severity of the swelling. For some people, it is caused by blood vessel dilation in the summer; for others, it is caused by allergies. In short, it is easy to treat once the cause is found.

1Hot summer: The heat causes blood vessels to dilate, allowing more heat to escape from the skin to keep body temperature from rising. At this time, some body fluid in the blood vessels will also flow to the soft tissue, causing edema. This swelling will gradually go away as you move your hands and continue your daily activities. But if you notice swelling only in your hands and fingers but not in your legs, and it's accompanied by mild pain or a loss of grip strength, it could be a sign of a medical condition and you should see a doctor as soon as possible.

2. Excessive salt intake: Restaurant dishes, purchased snacks, and any fried foods contain a lot of salt, which causes water to be retained in the body and causes edema. It is best to keep the body in a balance of water and salt. Taking in more salt means the body must retain more water to eliminate the saltiness, which can cause swelling. Generally speaking, swelling caused by the salt in the food will disappear within a day, but too much salt will make the swelling last longer. If you have reduced your salt intake and the swelling persists, you should see a doctor to check if there is another medical condition.

3 Osteoarthritis: If your finger joints become swollen, this may be one of the symptoms of osteoarthritis. This disease is caused by degeneration of cartilage in the joints and is more common in middle-aged and elderly people and obese people. Osteoarthritis is often accompanied by pain and stiffness, but not always. Many other types of arthritis can also cause swelling and pain in the fingers. Excessive hand activities should be avoided to reduce joint wear. Medication injections may also be given to reduce inflammation.
