The symptoms of hunger and shaky hands and feet are mainly considered to be caused by low blood sugar. When the body is starving and there is not enough food in the body to be transformed and absorbed by the digestive system, it will not only affect the normal functioning of various systems and tissues, but also lead to dysfunction of sympathetic nerves, central nerves and other nerve tissues. Therefore, it causes symptoms such as shaking of the hands and feet, frequent false sweating, panic, shortness of breath and other manifestations. However, many other systemic diseases can also cause such adverse symptoms, such as coronary atherosclerotic heart disease, neurasthenia syndrome, viral hepatitis, etc. The occurrence of these diseases can cause dysfunction of the cardiovascular system, nervous system, and digestive system, resulting in hunger and shaking of the hands and feet. If such adverse reactions persist or worsen, it is necessary to go to the hospital for further treatment as soon as possible to avoid delaying the disease.
