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 causing hyperphagia, increased food intake, and at the same time due to high blood sugar stimulates insulin secretion, thus the patient is prone to hunger, hyperphagia, always have a feeling of not being full, and side dishes are also significantly more than normal, still can not satisfy the appetite. Clinical diagnosis: 1. Increased urine volume, up to 3000-5000 ml per day and night, up to 10000 ml or more. The number of urination also increased, one or two hours may urinate once, and some patients even up to more than 30 times per day and night. Diabetic patients with increased blood sugar concentration, the body can not be fully utilized, especially the glomerular filtration and can not be completely reabsorbed by the renal tubules, resulting in the formation of osmotic diuresis, polyuria. The higher the blood sugar, the more urine sugar excreted, the more urine volume. 2. Drinking more Due to excessive urination, excessive water loss, intracellular dehydration occurs, which stimulates the thirst center and leads to thirsty drinking, and the amount and number of drinks increase as a way to replenish water. The more you urinate, the more you drink, forming a positive relationship. 3, more food easy to starve due to a large number of urine sugar loss, such as daily loss of sugar 500 grams or more, the body is in a semi-starvation state, the lack of energy needs to be supplemented to cause hyperphagia, increased food consumption. At the same time, high blood sugar stimulates insulin secretion, so the patient is prone to hunger, hyperphagia, always have a 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. 4, 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, and coupled with the loss of water, the patient loses weight and body weight, and in severe cases, the weight can drop 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.
