It is well known that the typical symptoms of diabetes are “three more and one less”, unfortunately, less than half of all diabetic patients have typical symptoms, and many patients have atypical symptoms, so it is more noteworthy, the common clinical symptoms are as follows.
Atypical symptoms
1. Pre-meal hypoglycemia
In the early stage of diabetes, some patients do not have the typical “three more and one less” symptoms, but often manifest as unbearable hunger and hypoglycemia before meals. The reason for this is that insulin secretion in type 2 diabetes is delayed and not synchronized with the change of blood glucose.
2.Abnormal sweating
Abnormal sweat secretion can occur in diabetic vegetative neuropathy, and even if the weather is not hot (especially when eating), sweating is often profuse, and mainly on the face and upper body, with less sweating on the lower limbs.
3. Gastrointestinal disorders
Diabetic vegetative neuropathy often affects the function of the gastrointestinal tract, slowing down the peristalsis and delaying gastric emptying, and patients show abdominal distension, poor appetite or stubborn constipation. In addition, there are a few patients who present with chronic diarrhea or alternating diarrhea and constipation, usually without abdominal pain and purulent stools, and with ineffective antibiotics.
Atypical symptoms
4. Difficulty in urination and retention of urine
Hyperglycemia can damage the vegetative nerves innervating the bladder and affect the contraction and emptying of the bladder, and the patient shows difficulty in urination, dribbling and urinary incontinence. If a diabetic patient develops these conditions, he or she should first consider prostate hypertrophy and also pay attention to exclude the presence of diabetes-induced “neurogenic bladder”.
5, postural hypotension
The diabetic plant neuropathy, resulting in vasodilatory dysfunction, when sitting, lying suddenly after standing up, because the blood vessels can not reflexively contract, resulting in a drop in blood pressure and cause transient cerebral ischemia, the patient appears dizzy, dazzling and even fainting.
6.Sexual dysfunction
Long-term hyperglycemia can lead to neurological and vascular lesions, thus causing male sexual dysfunction, so the middle-aged men with normal sexual function in the past, when impotence or erectile insecurity occurs, should promptly test blood sugar to exclude diabetes. According to the survey, about 50% of male diabetic patients have combined impotence.
Atypical symptoms
7. Recurrent urinary tract infections
Women have a shorter urethra and are inherently more prone to urinary tract infections than men. When diabetic patients have poor blood sugar control, the urine sugar content is high, and the urethra becomes the best breeding ground for various germs (bacteria, mold, etc.).
8. Itchy skin or boils
Some people feel itchy skin all the time for no reason, and have recurring boils on their skin, which can be a sign of diabetes. This is because high blood sugar can stimulate the skin nerve endings and cause itchy skin, especially itchy perineum is especially common in women. At the same time, due to the decrease of local resistance, the skin is easily infected with boils.
9.Loss of vision
Diabetes can cause retinopathy and cataract, thus affecting vision, and the incidence increases with the disease and age. Among them, diabetic retinopathy has the most serious impact on vision, often causing sudden vision loss due to retinal hemorrhage.
Atypical symptoms
10. Numbness in hands and feet
Diabetes can cause peripheral neuritis, which manifests as symmetrical numbness, pain, burning, and loss of sensation in the hands and feet, and some patients may have the feeling of walking on cotton.
11. Drowsiness and coma
Some elderly people with diabetes are unaware of it, but under the effect of certain triggers (such as severe dehydration, infection, etc.), it can cause hyperosmolar coma or ketoacidosis coma, the clinical performance is similar to cerebrovascular disease.
12.Wound does not heal for a long time
As diabetic patients often have peripheral vascular lesions, affecting the blood supply of the tissue around the wound, coupled with the serious loss of nutrition in diabetic patients, resulting in wound healing difficulties.
13, unexplained weight loss
Diabetic patients due to insufficient insulin secretion or insulin resistance leads to sugar utilization disorders, so that the body needs the energy can only be provided by the breakdown of body fat and protein, which leads to weight loss of patients.
