Feeling hungry and panicky may be due to physiological factors such as lack of eating, or low blood sugar, hyperthyroidism, diabetes and other causes. 1. Strenuous exercise leads to a large amount of energy consumption, lack of food leads to a lack of energy and other factors cause hunger, the body increases the blood supply to the tissues by increasing the heart rate, thus increasing the supply of energy function, at this time the blood sugar can be at the normal level. 2. Hypoglycemia: Normal blood glucose level is 3.9-6.1mmol/L, when blood glucose is lower than 2.8mmol/L, it will reflexively stimulate the sympathetic and parasympathetic nerves, which will lead to the symptoms of dizziness, panic, sweating, hunger, and fatigue, etc. It is often seen in over-dieting, over-feeding, and over-excessive eating. It is mostly seen in cases of excessive dieting and overwork. 3. Hyperthyroidism: thyroid cells secrete and synthesize a large number of thyroid hormones, which act on the cardiac muscle cells leading to panic, and act on the gastrointestinal smooth muscle leading to hyperperistaltic contraction and hyperdigestive function, so you will feel hungry and panicky. 4. diabetes: diabetic patients due to insulin resistance and other factors, the tolerance for hypoglycemia is weakened, generally in the normal blood glucose level that occurs hypoglycemic symptoms. Feeling hungry and panicky may be related to a variety of factors, it is recommended to consult a doctor for a clear diagnosis.
