What are the complications caused by long term high blood sugar?

The harm of high blood sugar is mainly manifested in the complications. Mild short-term high blood sugar is not very harmful to the body. However, long-term elevated blood sugar will affect all tissues and organs throughout the body, leading to complications.

Acute complications include: (1) Diabetic ketoacidosis: hyperglycemia, high serum ketones and metabolic acidosis are the main manifestations.

2) Hyperglycemic hyperosmolar state: characterized by severe hyperglycemia, no obvious ketoacidosis, significantly increased plasma osmolality, dehydration, and impaired consciousness. (3) Lactic acidosis:

Rare, but mortality is high. When lactic acidosis occurs, most patients have certain predisposing factors, and most of them are in a state of hypoxia.

Chronic complications include: (1) Diabetic nephropathy: refers to chronic kidney disease caused by diabetes.

Fatigue, edema, and renal failure may occur. (2) Diabetic retinopathy: It can cause blurred vision, decreased vision, visual field defects, and even blindness.

3) Diabetic neuropathy: It is divided into central neuropathy and peripheral neuropathy. Symmetrical numbness, pain, hyperesthesia, or decreased sensation may occur.

Autonomic neuropathy may manifest as tachycardia at rest, orthostatic hypotension, constipation, diarrhea, fecal incontinence, abnormal sweating, dryness, erectile dysfunction, urinary retention, etc. Cranial or spinal neuropathy may present with drooping eyelids, facial paralysis, ocular fixation, hearing loss, facial pain, etc. (4) Diabetic lower extremity vascular disease:

Intermittent claudication, rest pain in the lower extremities, ischemic ulcers, or gangrene. (5) Diabetic foot: It is one of the most serious and costly chronic complications of diabetes, which can lead to amputation and death.

There may be foot infections, ulcers, and tendons, bones, and joints may be affected.

High blood sugar can easily cause kidney disease, eye diseases, and blood clots in the limbs, depending on how high the blood sugar is more than 7 to 12.

Generally greater than fasting. Diabetic patients are prone to infectious diseases when their blood sugar is not well controlled, including diabetic ketoacidosis, lung infection, urinary tract infection, ** infection, because the elevated blood sugar is conducive to the survival of various microorganisms. Chronic complications of diabetes mellitus are generally macrovascular lesions, microvascular lesions and neurological lesions, which are related to the length of onset.

If glycemic control is not good, chronic complications may appear early, and if glycemic control is largely achieved, the onset of chronic complications may be delayed. Under normal circumstances, if diabetes is not intervened, chronic complications can occur after about 5-8 years. If blood glucose control is achieved, chronic complications may not occur until 10-15 years later, so diabetic patients should control their blood sugar well and minimize the occurrence of various acute and chronic complications, because these chronic complications are the main factors that cause disability and blindness in diabetic patients.

If there is no history of diabetes, if you find high blood sugar, you should go to the hospital to find out whether you have diabetes. The causes of type 1 diabetes are complex and have a certain correlation with autoimmunity; There is a certain correlation between the causes of type 2 diabetes and heredity, poor lifestyle habits, work and rest habits, and dietary habits. If you already have diabetes, your blood sugar is still very high, because you don't choose medication and insulin according to your doctor's instructions**; Or in the process of **, without the guidance of an endocrinologist, to carry out appropriate exercise for dietary control.

Poor dietary control, inadequate exercise, and not taking medication as prescribed by the doctor may lead to inaccurate blood sugar control and high blood sugar in diabetic patients.

Complications occur when blood sugar levels exceed this level. It may be due to the poor metabolism in your body, the sugar content is too high, and your body's digestion ability is not particularly good, which leads to high blood sugar.

Complications can occur if it is greater than 10 for a long time. Usually often tired, infected with viruses, stroke, often eat high-sweet and high-calorie food, often stay up late, and be stressed, which will lead to high blood sugar.

Complications occur in as high as 5% of cases. It is usually caused by eating a lot of greasy things, or not exercising regularly.

Complications of diabetes usually appear gradually after 10 years, and if blood sugar is not well controlled, complications will appear more quickly. So be aggressive in controlling your blood sugar.

Complications usually occur when blood sugar is high above 20 or 30. Therefore, you must pay attention to your diet and don't eat high-sugar, high-calorie, and greasy things. It's better to eat more whole grains, such as whole-grain bread.

Everyone's physical condition is different, and the standard of high blood sugar is also different, but if it is 4 plus signs, you should pay more attention, and there will be a series of high blood sugar and high blood lipids, but the specific needs to be judged after examination.

There are complications before hyperglycemia.

The body really is everything! From the time my dad got sick to the time he died, it was as long as it took me to finish my whole life! I don't know how to eat, and I don't even feel hungry! I can't describe how it feels!

Blockage of the capillaries in the fundus will cause vision loss, fundus lesions, and poor microcirculation on the hands and feet, which will cause cold and numbness of the limbs; Coronary heart disease occurs when the blood flow in the large and middle arteries around the heart is poor, and cerebral infarction and stroke occur if the blood flow in the brain is poor.

Diabetes is not terrible, but what is terrible is the complications caused by diabetes. What are the possible complications of diabetes?

When the blood sugar is generally greater than 16 mmol L, complications are likely to occur, and ketoacidosis may occur. The higher the blood sugar, the greater the chance of complications. If blood sugar is maintained at a relatively high level for a long time, it is prone to diabetic retinopathy, diabetic nephropathy, diabetic cardiovascular and cerebrovascular diseases and other diseases.

There is also a relationship between high and low blood sugar and the individual's constitution. Some people have low blood sugar but serious complications, and some people have high blood sugar but not many complications, and there are certain differences. Patients with diabetes should pay attention to blood sugar control, and blood sugar control can reduce the chance of complications.

High blood sugar for a long time will definitely lead to associated vascular changes. If the blood sugar is very high, there may be some acute complications, such as more serious diabetic ketoacidosis or coma with high renal diabetes, in this case, the blood sugar may often reach more than 30 or the blood glucose meter cannot be detected at all, and some people's blood sugar may reach more than fifty or sixty.

Then there are related chronic complications such as diabetic peripheral neuropathy, diabetic nephropathy, and diabetic disease with macrovascular lesions. In this condition, blood vessels are narrowed due to fluctuations in blood sugar due to uneven blood sugar maintenance.

In general, diabetes complications occur when blood sugar rises significantly. Studies have shown that if the fasting blood glucose is significantly higher than or the postprandial blood sugar is significantly increased, the damage to the diabetic macrovascular vessels will be aggravated, and the corresponding cerebral blood supply insufficiency, carotid plaque and myocardial insufficiency will occur, coronary heart disease, angina pectoris, myocardial infarction or cerebral artery insufficiency, cerebral infarction and other symptoms. Secondly, when the blood sugar is slightly elevated, there will be an impact on microvascular complications, such as when the blood sugar is greater than that, there will be a serious impact on the microvasculature of the fundus, diabetic retinopathy and aggravation of diabetic nephropathy, proteinuria, edema, increased blood pressure and other symptoms, and even aggravate peripheral nerve lesions.

Fasting blood sugar should be maintained at about 6, and postprandial blood sugar should be maintained at about 8, if blood sugar can be controlled stably, it will not cause complications; If your blood sugar is not controlled, it means that your body's metabolism has been disordered, and blood pressure and blood lipids will increase to varying degrees, which will increase the risk of such diseases.

Yes, diabetes will generally form complications after a few years, if it is not well controlled, it will cause great damage to the organs of the human body, usually or eat less sugar, less salt, less greasy food, do not eat high-calorie, greasy things.

Not necessarily how high the blood sugar will cause complications, according to your own physical fitness, when the body blood sugar is too high, it will cause a huge burden on the cardiovascular system, and it is very easy to cause blood lipids and cardiovascular diseases.

1. Blood sugar greater than 25 mmol or more will cause complications, and it is easy to have some complications of diabetes, ketoacidosis and diabetic coma.

2. If the blood sugar is high for a long time, such as long-term diabetes blood sugar control is not good, it is easy to have some diabetic nephropathy, diabetic peripheral neuropathy, diabetic retinopathy, and some diabetic vascular lesions.

3. To analyze according to the specific situation, it is necessary to control blood sugar in an appropriate range for a long time. It can be adjusted through exercise, and if necessary, it may require some hypoglycemic drugs, insulin to control blood sugar, and a reasonable blood sugar control plan should be formulated according to the specific blood sugar level.

When the blood sugar is high to 12, it is easy to have nausea, vomiting, coma, blindness, high blood pressure, high blood lipids, etc. High blood sugar can cause metabolic disorders, so there are many complications.

Normal blood sugar is there, once it exceeds this range in a short period of time, you should pay attention to your body and go to the hospital for a check-up.

In general, patients with blood sugar levels above are most likely to develop complications. Because this level of blood sugar is already very high.
