1. Unbearable itching is not a gynecological disease or diabetes

1. Diabetes causes skin pruritus due to many aspects: 1. Increased blood sugar makes plasma and tissue fluid in a hypertonic state, causing intracellular dehydration, dry skin, and irritating nerve endings;

2. Due to nutritional and metabolic disorders, diabetic patients are often accompanied by nerve ending inflammation, which causes increased nerve sensitivity. External stimuli such as changes in cold and heat, clothes friction, drinking and spicy food can all induce skin itching;

3. The increase in blood sugar also weakens the bactericidal ability of white blood cells, resulting in a decline in skin immune function, easy to be infected with folliculitis, tinea corporis and other diseases, causing skin itching.

Therefore, when the patient has exhausted all kinds of desensitization drugs and topical liniments, and still can not solve the problem of skin itching, blood sugar should be checked to be alert to diabetes.

2. Can eat and drink, but light weight

Case: Mr. Li ate more three meals a day than usual. He always feels hungry between work and needs snacks to fill his hunger. In addition to being able to eat, I drink water more frequently than before. I have to go to the toilet four or five times a morning, but my mouth becomes dry soon after drinking. However, Mr. Li, who can eat and drink, didn't get any blessings. He lost his weight when he weighed in. This caused concern in his family.

Expert interpretation: Mr. Li's symptoms are the most typical "three more and one less" symptoms of diabetes, that is, eating more, drinking more, urinating, and losing weight.

Eat more: a lot of urine sugar, the loss of sugar causes the human body to lack energy and is in a hungry state, which leads to hyperappetite and a large increase in food intake. In addition, the increase in blood sugar will stimulate insulin secretion, making patients more likely to feel hungry. Some patients even have to eat five or six meals a day, but still can't find the feeling of "full".

Polydipsia: Polyuria will be accompanied by water loss, causing intracellular dehydration, which will stimulate the thirst center, dry mouth, polydipsia and polydipsia, which will lead to an increase in the frequency and amount of drinking water. Add water.

Polyuria: Diabetes patients are often accompanied by elevated blood sugar, the sugar cannot be fully utilized, and the glomeruli cannot be completely reabsorbed by the renal tubules after being filtered out, resulting in osmotic diuresis and polyuria. The higher the blood sugar, the more sugar in the urine and the more urine output. At the same time, polyuria leads to polydipsia, which promotes polyuria.

Weight loss: Due to insufficient insulin, the human body cannot make full use of glucose for energy, and replenish energy and calories by accelerating the decomposition of fat and protein, resulting in a large consumption of fat and protein in the body, coupled with the loss of water, patients often lose weight , Body weight loss, causing fatigue, weakness and listlessness.

"Three more and one less" are typical symptoms of diabetes, which should not be taken lightly. But this does not apply to everyone. Some patients with early diabetes do not have this kind of situation, but are only accompanied by fatigue, pre-meal hypoglycemia, skin itching, sexual dysfunction, numbness of hands and feet and other discomforts, so you must be especially vigilant.

Three, flustered and shaking hands indicate hypoglycemia

Case: 50-year-old Ms. Cui is in good health, but a strange phenomenon has appeared in the past six months. Every time before the meal, I feel flustered, shaking hands, sweating, feeling weak, and feeling very hungry. After I eat something, I feel better immediately. At first, Ms. Cui didn't care, thinking it was hypoglycemia caused by not eating at the meal. For this reason, Ms. Cui slightly increased her appetite, but her symptoms became more and more obvious without thinking. Worried, Ms. Cui came to the hospital for an examination and was diagnosed with pre-diabetes, which made her very puzzled, "I suffer from hypoglycemia every day, how can it be diabetes?"

Expert interpretation: This condition is called "pre-meal hunger phenomenon", which is a very important symptom of pre-diabetes, which is more common in people who are obese. This situation occurs because various mechanisms in the early stage of diabetes weaken the physiological effects of insulin. In order to maintain normal blood sugar, it needs to secrete a large amount of insulin. Over time, it will damage the pancreatic β cells that secrete insulin, and gradually slow down the secretion of insulin. The secretion peak is delayed, so that the peak that should appear 10 minutes to half an hour after eating is shifted to 2 to 3 hours after the meal. As a result, there is not enough insulin after the meal to control the increase in blood sugar, but before the next meal, it is due to insulin. Causes low blood sugar.

For patients with similar symptoms, it is best to see a doctor as soon as possible, and get a clear diagnosis through oral glucose tolerance and insulin release tests.

Fourth, numbness and weakness of hands and feet to be alert to neuropathy

Case: Six months ago, Uncle Liu often felt that his legs and feet were numb, and he did not get any better after six months of massage and feet. Later, Uncle Liu felt that the numbness slowly developed to his arms and hands, and at the same time the condition of his lower limbs became heavier, and he often felt worms crawling into his trouser legs. For this reason, Uncle Liu's children immediately took him to the hospital for an examination and was diagnosed with diabetes.

Expert interpretation: Uncle Liu's condition is peripheral neuralgia caused by diabetes. This condition mostly occurs in middle-aged and elderly people. Patients often have slight numbness or dullness in their hands and feet. Generally, they don't pay attention to it. They think it is a natural function caused by aging. Degenerate. Diabetic peripheral neuralgia can greatly affect life. Patients often feel numbness in their lower limbs, like a small worm crawling, and feel fever, even like an electric shock, or severe pain such as tingling, burning, and drilling pain, which is light during the day and heavy at night. In severe cases, lower extremity ulcers may also appear, and long-lasting diabetic feet may appear. Once middle-aged and elderly people find leg numbness, don't be careless. They must go to the neurology and endocrinology department in time to make a clear diagnosis and relieve the pain as soon as possible. There are currently approximately 140 million diabetic patients in the world, and it is estimated that by 2025, there will be 300 million people. Experts say that due to the insidious onset of diabetes, many patients do not know that they have diabetes before they show typical clinical symptoms. Typical symptoms include polydipsia, polyphagia, polyuria, weight loss, fatigue, irritability, blurred vision, etc. This article will reveal several typical signs of diabetes through several cases, hoping to help the majority of patients.
