Chronic hyperglycemia and glycemic control -
When the mechanisms fail in a way that allows glucose to rise to abnormal levels, hyperglycemia is the result. Ketoacidosis may be the first symptom of immune-mediated diabetes, particularly in children and adolescents.
Also, patients with immune-mediated diabetes, can change from modest fasting hyperglycemia to severe hyperglycemia and even ketoacidosis as a result of stress or an infection. Obesity has been contributing to increased insulin resistance in the global population.
Insulin resistance increases hyperglycemia because the body becomes over saturated by glucose. Insulin resistance desensitizes insulin receptors, preventing insulin from lowering blood sugar levels.
The leading cause of hyperglycemia in type 2 diabetes is the failure of insulin to suppress glucose production by glycolysis and gluconeogenesis due to insulin resistance.
Certain medications increase the risk of hyperglycemia, including: corticosteroids , octreotide , beta blockers , epinephrine , thiazide diuretics , statins , niacin , pentamidine , protease inhibitors , L-asparaginase , [22] and antipsychotics.
Thiazides are used to treat type 2 diabetes but it also causes severe hyperglycemia. A high proportion of patients with an acute stress such as stroke or myocardial infarction may develop hyperglycemia, even in the absence of a diagnosis of diabetes.
Or perhaps stroke or myocardial infarction was caused by hyperglycemia and undiagnosed diabetes. Stress causes hyperglycaemia via several mechanisms, including through metabolic and hormonal changes, and via increased proinflammatory cytokines that interrupt carbohydrate metabolism, leading to excessive glucose production and reduced uptake in tissues, can cause hyperglycemia.
Hormones such as the growth hormone, glucagon, cortisol and catecholamines, can cause hyperglycemia when they are present in the body in excess amounts. It is critical for patients who monitor glucose levels at home to be aware of which units of measurement their glucose meter uses.
Glucose levels are measured in either: [ citation needed ]. Glucose levels vary before and after meals, and at various times of day; the definition of "normal" varies among medical professionals. Sustained higher levels of blood sugar cause damage to the blood vessels and to the organs they supply, leading to the complications of diabetes.
Chronic hyperglycemia can be measured via the HbA1c test. Defects in insulin secretion, insulin action, or both, results in hyperglycemia. Chronic hyperglycemia can be measured by clinical urine tests which can detect sugar in the urine or microalbuminuria which could be a symptom of diabetes.
Treatment of hyperglycemia requires elimination of the underlying cause, such as diabetes. Acute hyperglycemia can be treated by direct administration of insulin in most cases. Severe hyperglycemia can be treated with oral hypoglycemic therapy and lifestyle modification.
In diabetes mellitus by far the most common cause of chronic hyperglycemia , treatment aims at maintaining blood glucose at a level as close to normal as possible, in order to avoid serious long-term complications.
This is done by a combination of proper diet, regular exercise, and insulin or other medication such as metformin , etc. Those with hyperglycaemia can be treated using sulphonylureas or metformin or both. These drugs help by improving glycaemic control.
Hyperglycemia can also be improved through minor lifestyle changes. Increasing aerobic exercise to at least 30 minutes a day causes the body to make better use of accumulated glucose since the glucose is being converted to energy by the muscles.
Diets higher in healthy unsaturated fats and whole wheat carbohydrates such as the Mediterranean diet can help reduce carbohydrate intake to better control hyperglycemia. Carbohydrates are the main cause for hyperglycemia—non-whole-wheat items should be substituted for whole-wheat items. Although fruits are a part of a complete nutritious diet, fruit intake should be limited due to high sugar content.
Hyperglycemia is lower in higher income groups since there is access to better education, healthcare and resources. Low-middle income groups are more likely to develop hyperglycemia, due in part to a limited access to education and a reduced availability of healthy food options.
Hyperglycemia is one of the main symptoms of diabetes and it has substantially affected the population making it an epidemic due to the population's increased calorie consumption. The origin of the term is Greek : prefix ὑπέρ- hyper- "over-", γλυκός glycos "sweet wine, must ", αἷμα haima "blood", -ία, -εια -ia suffix for abstract nouns of feminine gender.

Later signs and symptoms If hyperglycemia isn't treated, it can cause toxic acids, called ketones, to build up in the blood and urine. Symptoms include: Fruity-smelling breath Dry mouth Abdominal pain Nausea and vomiting Shortness of breath Confusion Loss of consciousness.

Many factors can contribute to hyperglycemia, including: Not using enough insulin or other diabetes medication Not injecting insulin properly or using expired insulin Not following your diabetes eating plan Being inactive Having an illness or infection Using certain medications, such as steroids or immunosuppressants Being injured or having surgery Experiencing emotional stress, such as family problems or workplace issues Illness or stress can trigger hyperglycemia.
Long-term complications Keeping blood sugar in a healthy range can help prevent many diabetes-related complications. Long-term complications of hyperglycemia that isn't treated include: Cardiovascular disease Nerve damage neuropathy Kidney damage diabetic nephropathy or kidney failure Damage to the blood vessels of the retina diabetic retinopathy that could lead to blindness Feet problems caused by damaged nerves or poor blood flow that can lead to serious skin infections, ulcerations and, in some severe cases, amputation Bone and joint problems Teeth and gum infections.
Emergency complications If blood sugar rises very high or if high blood sugar levels are not treated, it can lead to two serious conditions.
To help keep your blood sugar within a healthy range: Follow your diabetes meal plan. If you take insulin or oral diabetes medication, be consistent about the amount and timing of your meals and snacks.
The food you eat must be in balance with the insulin working in your body. Monitor your blood sugar. Depending on your treatment plan, you may check and record your blood sugar level several times a week or several times a day. Careful monitoring is the only way to make sure that your blood sugar level stays within your target range.
Note when your glucose readings are above or below your target range. Carefully follow your health care provider's directions for how to take your medication.
Adjust your medication if you change your physical activity. The adjustment depends on blood sugar test results and on the type and length of the activity.

Treatments to improve glycemic management work by increasing insulin availability either through direct insulin administration or through agents that promote insulin secretionimproving sensitivity to insulin, delaying the delivery and absorption of carbohydrate from the gastrointestinal tract, increasing urinary glucose excretion, or a combination of these approaches. For patients with overweight, obesity, or a metabolically adverse pattern of adipose tissue distribution, body weight management should be considered as a therapeutic target in addition to glycemia. Methods used to manage blood glucose in patients with newly diagnosed type 2 diabetes are reviewed here.
Ich entschuldige mich, aber meiner Meinung nach irren Sie sich. Ich biete es an, zu besprechen. Schreiben Sie mir in PM, wir werden umgehen.
