Do not let the complexity of diabetes medical misdiagnosis

With the popularization of science knowledge, the mention of the diabetic people often think of "a little over 3" - polyuria, polydipsia, polyphagia and weight loss symptoms. In fact, the clinical symptoms of diabetes are complex and changeable, especially in the elderly suffering from diabetes, the typical symptoms are not very clear, often due to severe cardiovascular disease and eye, neuropathy or infection or even unconscious to the hospital, was finally confirmed as diabetes. Therefore, to identify diabetes, we except to note that "more than three a little" symptom, but also about other non-typical symptoms, so they are not to missed.

Not the typical elderly diabetic common symptoms are:

Limbs.

This is a common symptom of diabetes. This is because diabetes can not make full use of glucose released energy efficient, with tissue dehydration, electrolyte imbalance, there will be generalized weakness, lassitude.

Vascular lesions.

Macrovascular disease can cause coronary heart disease, hypertension, cerebrovascular disease and arterial sclerosis. Common microvascular complications of diabetes, retinopathy, diabetes, kidney disease, diabetic retinopathy is the main reason for the elderly blind; diabetic nephropathy can lead to renal insufficiency, uremia eventually occur. Some studies have shown clinical dialysis patients, diabetes caused by 60% to 80%.

Eye.

In addition to diabetes can cause retinopathy, it can also cause a variety of eye diseases, such as corneal ulcers, glaucoma, cataract, vitreous hemorrhage. Many people with diabetes in the eye doctor first. Therefore, if the elderly find that vision suddenly diminished, not only to think to eye examinations, there is no guard against diabetes.

Neuropathy.

Diabetic neuropathy is divided into peripheral neuropathy, cranial neuropathy and autonomic neuropathy, clinical symptoms are diplopia, seeing out of ghosting, urinary retention, voiding difficulty, etc., but the most common is numbness of the feet and fingers, stabbed pain and sensory dysfunction, severe muscle atrophy can occur, nerve paralysis and limb paralysis, hearing loss and Kouyanwaixie so.

Immune dysfunction.

High blood sugar inhibits the immune function, and provide rich nutrients for the pathogen, so people with diabetes can cause tuberculosis, lung infection, biliary tract infections, urinary tract infections, and ferocious, difficult to control. In addition, lower extremity nerve, blood vessel disease, with a combination of infection, diabetes-prone diabetic foot, leg ulceration occurs, necrosis, severe cases can lead to amputation.

As the high incidence of diabetes, complications, serious consequences, it has been following the cancer, cardiovascular disease became serious harm to human life and health of the third killer, therefore, should pay close attention. The elderly in the event of the above, should go to the hospital for appropriate examination. Determination of blood glucose is the sole criterion for diagnosis of diabetes. Fasting blood glucose greater than or equal to 7 mmol / l, 2-hour postprandial blood glucose greater than or equal to 11.1 mmol / L, the exclusion of other causes blood sugar, diabetes can be diagnosed. If the range between 2 and can be used glucose tolerance test.

It is worth noting that many elderly people suspect that they have diabetes to the hospital for fasting blood sugar screening, blood sugar not meet diagnostic criteria, we believe they do not diabetes, off guard. In fact, about half of elderly diabetics, fasting plasma glucose may not be as high as 7 mmol / liter, and 2 hour blood glucose will be greater than 11.1 mmol / l, if only do fasting glucose, postprandial blood glucose do not , easily lead to missed diagnosis. This is because some of the elderly overcome their early insulin secretion in vivo hormone effects blood sugar rise, but not enough to overcome the postprandial hyperglycemia.
