The shaking of hands when you are hungry is mainly considered to be caused by hypoglycemia. Because the body in the case of hunger, low blood sugar will stimulate the secretion of hormones that raise blood sugar, like adrenal hormones, glucocorticoids and so on. The secretion of these hormones will stimulate the excitation of sympathetic nerves, resulting in symptoms such as shaking hands, panic, sweating, dizziness, lack of strength and pallor. Therefore, if you are hungry and have trembling hands, it is recommended that you can measure your blood sugar, and if your blood sugar is low, it is recommended that you need to immediately eat some foods that are high in sugar, like sugar cubes and chocolates. If this situation occurs frequently, it is recommended that you also need to go to the hospital to check to see if there is a problem with insulin secretion, there is no diabetes and other diseases.
