When a person suffers from lifelong diseases and needs long-term diet conditioning and various complicated treatment and examination, it does bring a lot of inconvenience and distress to work and life, especially when the patient knows that diabetes will accompany him all his life. The incurability of the disease and the adverse consequences caused by various serious complications cast a shadow on the patient's mind and produced fear, so he sought medical treatment everywhere and went to the hospital in all directions. This eagerness to seek medical treatment will delay treatment and lead to aggravation of the condition; Second, expectations are often frustrated and lost, which is easy to produce negative psychology. Such patients often can't actively cooperate with doctors, which brings difficulties to clinical treatment. Doctors found in clinical work that patients' bad emotions often affect their recovery, especially female patients aged 40-50 and logical patients aged 60-70, whose emotions change greatly. This may be due to mental stress or menopausal mood fluctuation, which causes sympathetic nerve excitement, which leads to the increase of blood sugar level and the recurrence of the disease. In addition, some patients are indifferent to their illness, have no scruples and go their own way; Some patients are listless, depressed and even refuse to receive treatment; The mood of most patients is influenced by blood sugar and urine sugar. When the indicators are normal or close to normal, they think they are completely cured, so they relax their diet and even stop taking hypoglycemic drugs themselves. When the index rises sharply and symptoms reappear, I feel nervous and afraid. The mood of these patients fluctuates greatly, which is not conducive to the control of the disease. Emotional factors play an important role in the occurrence, development and recurrence of diabetes, which has been recognized by scholars all over the world. Negative emotions such as nervousness, excitement, depression, and fear will cause a large increase in the secretion of some stress hormones. These hormones are: growth hormone secreted by pituitary gland, norepinephrine secreted by nerve endings, glucagon secreted by islet α cells, adrenaline secreted by adrenal gland and adrenocortical hormone. These kinases are hormones that raise blood sugar and fight against insulin, which leads to repeated illness and affects the rehabilitation of diabetic patients. Examples are as follows: Example 1: Female patient, 50 years old. After clinical treatment, the symptoms of diabetes have disappeared and the indexes of blood sugar and urine sugar are normal. But I quarreled with others because of a small matter, and I was angry and crying. The next day, I felt chest tightness and dizziness, with fasting blood glucose as high as 19.3 mmol/L (345 mg/dl) and urine sugar (++). Example 2: An elderly male, 70 years old. He believes that diabetes can't be cured and can't die. He is careless and overeating. Because blood sugar is at a high level for a long time and complicated with nephropathy (involving renal tubules), proteinuria and edema of lower limbs have appeared. At this time, the patient was in a hurry. After patient ideological work, he understood that diabetes is a chronic progressive disease and consciously controlled his diet. In the future treatment, with good cooperation, blood sugar will gradually decrease and symptoms will be significantly improved. It can be seen that it is very important to stabilize patients' thoughts and emotions, eliminate factors that are not conducive to diabetes treatment, and help patients establish confidence in overcoming the disease.
