Easy hunger means feeling hungry again after eating for a short while, it is a symptom of overeating, mainly to rule out the absence of hyperthyroidism and possibly suffering from diabetes. The lack of energy needs to be replenished to cause hyperphagia, the amount of food increases, and at the same time, because of high blood sugar stimulates insulin secretion, so the patient is easy to produce hunger, hyperphagia, always have the feeling of not being full, side food is also significantly more than normal people, but still can not meet the appetite. Symptoms that can be easily confused with hunger: 1, overeating: due to the loss of a large amount of urine sugar, such as the loss of more than 500 grams of sugar per day, the body is in a semi-starvation state, the lack of energy needs to be supplemented to cause hyperphagia, increased food. At the same time, high blood sugar stimulates insulin secretion, so the patient is prone to hunger, hyperphagia, always have the feeling of not being full, and even eat five or six times a day, the main food up to 1 ~ 1.5 kg, side dishes also increased significantly than normal people, but still can not meet the appetite. 2, wasting: due to insufficient insulin, the body can not make full use of glucose, so that fat and protein decomposition accelerated to replenish energy and heat. As a result, carbohydrates, fats and proteins in the body are consumed in large quantities, coupled with the loss of water, the patient loses weight and body weight, and in severe cases, the weight can be reduced by tens of pounds, resulting in fatigue and weakness, and mental inactivity. Similarly, the longer the duration of the disease, the higher the blood sugar; the more serious the disease, the more obvious the wasting.
