Cold hands alone may be caused by a variety of causes such as cervical and lumbar spondylosis and heart function, which are considered by Chinese medicine to be mostly caused by kidney yang deficiency and deficiency of qi and blood, not necessarily a sign of kidney deficiency. In general, when a patient with cold hands has a red tongue with yellow and thick greasy tongue coating, it is usually not considered a kidney deficiency. When the patient has a pale tongue with symptoms such as fatigue, weakness, mental inactivity, fear of cold, cold pain in the back, soreness and weakness of the waist and knees, and men have symptoms such as decreased libido, seminal emission, premature ejaculation and impotence; women have symptoms such as uterine cold and infertility, thin and clear leucorrhoea and menstrual disorders, it usually suggests possible kidney yang deficiency. Therefore, patients are advised to go to the Chinese medicine department of a regular hospital in a timely manner to clarify the specific diagnosis in order to prescribe the right medicine, and it is better to determine the disease first before using the medicine. It is recommended that people with cold hands pay attention to keeping warm, soak their hands and feet in warm water, eat more warm foods such as mutton and beef, and pay attention to the regularity of work and rest. If you are diagnosed with kidney deficiency, you should actively cooperate with the treatment, avoid taking cold, spicy food, moderate the number of sexual intercourse, and participate in outdoor sports.
