The so-called minor ailments are those that people think are painless, itchy or not very painful, do not affect food and drink, do not affect work, do not need injections and infusions, do not need hospitalization, do not need surgery. In fact, people often do not care about this small disease is the early signals of major diseases, such as bladder cancer, the earliest signal may be half a year before a painless hematuria; the same transient deactivation or numbness of the hands and feet is the precursor of cerebral thrombosis after a few months; a slight heart area of the front of the heart may be a few hours after a fatal myocardial infarction. From this we can see that the human body’s mild discomfort or minor abnormalities, by the general public seems to be a minor problem, may indicate a big hidden trouble. 35-year-old civil servant Zhang, because of the inconvenience of the place of the disease, began to self-treatment, and then went to a small clinic, after infusion and injection is not effective, but also have been to a large hospital, due to acquaintances did not check, but only prescribed ointment and oral medication. Although the mood is apprehensive, but always think it is not a big disease, six months later to the four hospitals urology outpatient clinic, by the doctor a short inquiry and physical examination, diagnosed as the circumcision glans, may be a complication of diabetes mellitus. Xiao Zhang was very annoyed at that time, and said excessive words to the doctor, firmly denied that he had diabetes. After a patient explanation by the doctor, a urine test was carried out and the urine sugar was ++. The guy was dumbfounded, a minor problem, how could this happen? Surprised – upset – skeptical. The next day the fasting blood sugar test, the result is 11.8mmol / L, in front of the irony of the guy finally convinced. In the internal medicine doctor’s guidance through the standardized treatment of diabetes, and in a month after the circumcision, not only said goodbye to half a year’s hidden, more importantly, the doctor was able to find out through a small disease diabetes – a big hidden trouble, the guy on the urologist’s keen eyes and rich experience grateful. The foreskin glansitis is a common disease in male medicine, common in spring and summer, common in the circumcision or circumcision, the lesion is only limited to the mucous membrane of the foreskin glans, for the infectious or irritating inflammation, the light one is washed away, the heavy one is itchy, milky secretion and the foreskin is cracked, thickened as the main manifestation. Despite the minor problems, life is a big trouble, because of the special parts of the patient is difficult to talk about, often self-treatment, most doctors also treated as a general infection, often misdiagnosed, mistreated. Practice has proved that the glans penis is mostly caused by fungi, and more than 90% for diabetes induced, called diabetic glans penis. Characterized by recurrent episodes of inflammation that do not heal, a variety of therapeutic effects are not good, the patient lacks the typical three more and one less symptom of diabetes. Because most of the glans penis for the first manifestation of type 2 diabetes mellitus, but also one of the clues of early diabetes, urologist advice: glans penis, even young patients can not ignore the monitoring of diabetes, do not repeatedly apply antibiotics, especially salacin antibiotics, which may aggravate the condition of diabetes mellitus. Man is a highly automated machine, every cell change may eventually endanger life, like a car often maintenance, often check, found small problems, small problems to find the root cause in a timely manner, otherwise it may lead to big trouble or even a big disaster, it is too late to regret. Disease manifestations and the severity of the disease is not directly related, when the ureteral stone patients severe pain, precisely indicates that the stone is being discharged to the end of the urinary tract, is about to be excluded from the omen, and painless ureteral stone may indicate that the stone long stay local ureteral obstruction, seriously affecting the renal function. As a doctor to constantly enrich their professional and basic knowledge, but also to do a comprehensive, systematic analysis of every small physiological and biochemical changes, from the surface to the inside, inside and outside; left and right analysis, up and down comparisons; tracing the root causes, dialectical treatment; with the philosophical thinking of medicine, standardize the use of modern medical technology to diagnose and treat diseases for the benefit of mankind.
