Swollen hands in the morning to observe the urine color changes, such as urine becomes cloudy and a lot of foam, urine is red, or monitor the blood pressure has a significant increase, consider that there may be kidney problems, such as nephritis or nephrotic syndrome. Swelling of the hands due to kidney problems is the most common cause. In addition, if there is a history of chronic bronchitis and wheezing in winter, which can lead to right heart failure in the long run, swelling of the hands can also occur, and can be examined by chest radiographs, cardiac ultrasound, and so on. If there is a history of hepatitis B and the liver function has obvious abnormalities, we should exclude the hand swelling caused by liver cirrhosis. If all of the above have been ruled out, there is another type of hypothyroidism, which is easy to miss and is also a cause of hand swelling. The patient will have symptoms such as fear of cold, anemia, dry stools, etc. To confirm the diagnosis, thyroid function tests should also be performed.
