Glucose Level Testing: A Vital Step In Stroke Diagnosis

Hyperglycemia, or high levels of glucose, is common in patients with acute ischemic stroke and is associated with worse outcomes compared to normal blood sugar levels. High blood sugar levels can damage blood vessels, increasing the chance of stroke. Therefore, it is important to monitor blood glucose levels in patients with diabetes to prevent stroke. However, intensive glucose management after acute ischemic stroke may not lead to better outcomes. More research is needed to understand the role of glucose in stroke recovery and to identify additional treatments to improve outcomes in hyperglycemic stroke patients.

High glucose levels can damage blood vessels, increasing the chance of stroke

Diabetes is a condition that causes blood sugar to rise. A fasting blood glucose level of 126 milligrams per decilitre (mg/dL) or higher is considered dangerous. People with diabetes are twice as likely to have a stroke as those without. They also tend to develop heart disease or have a stroke at an earlier age. Every two minutes, an American adult with diabetes is hospitalised for a stroke.

The connection between diabetes and stroke lies in how the body handles blood glucose to make energy. Most food we eat is broken down into glucose to give us energy. Glucose enters the bloodstream and travels to cells throughout the body after food digestion. For glucose to enter cells and provide energy, it needs a hormone called insulin.

In people with type 1 diabetes, the pancreas does not make insulin. In type 2 diabetes, the pancreas either makes too little insulin, or muscles, the liver, and fat do not use insulin correctly. As a result, people with untreated diabetes end up with too much glucose in their blood, leaving their cells unable to receive enough energy. Over time, excessive blood glucose can increase fatty deposits or clots in blood vessels that may lead to stroke.

Managing diabetes and lowering your risk of stroke involves getting tested regularly and talking with your doctor to ensure you're doing all you can to stay healthy. It's also important to know the signs of stroke so you can get quick medical attention. Some of the signs of stroke include trouble talking, dizziness, severe sudden headache, trouble seeing or double vision, and weakness or numbness on one side of the body.

Hyperglycaemia is common in patients with acute ischemic stroke and is associated with worse outcomes

Hyperglycaemia, or high levels of glucose, is a common occurrence in patients with acute ischemic stroke. This condition is associated with worse outcomes compared to those with normal blood sugar levels. The link between hyperglycaemia and acute ischemic stroke has been the subject of much debate among stroke experts, who have questioned whether intensive glucose management after acute ischemic stroke leads to improved patient outcomes.

The Stroke Hyperglycemia Insulin Network Effort (SHINE) study, a large-scale, multi-site clinical investigation, compared two commonly used glucose control strategies in ischemic stroke patients. Over 1100 patients were subjected to either intensive glucose management, which involved intravenous insulin administration to lower blood sugar levels to 80-130 mg/dL, or standard glucose control using insulin shots, aiming for glucose levels below 180 mg/dL for up to 72 hours. The results revealed that both treatments were equally effective in aiding patient recovery from strokes. After 90 days, approximately 20% of patients exhibited favourable outcomes, regardless of the treatment method.

Intensive glucose therapy, however, presented an increased risk of very low blood glucose levels (hypoglycaemia) and required a higher level of care, including increased supervision from nursing staff. The study concluded that the extra risks associated with aggressive treatment did not justify the outcomes, and thus, aggressive methods were not superior to standard approaches. This finding provides strong clinical evidence that aggressive lowering of blood glucose does not improve patient outcomes.

While the exact role of glucose in stroke recovery remains to be fully understood, the SHINE study offers valuable insights into the management of blood sugar levels in acute stroke patients. Further research is needed to identify additional treatments that can improve outcomes for hyperglycaemic stroke patients and to determine whether high blood sugar is a cause or consequence of adverse stroke outcomes.

Intensive glucose management after acute ischemic stroke does not lead to better outcomes than standard approaches

Hyperglycemia, or high levels of glucose, is a common occurrence in patients with acute ischemic stroke and is associated with worse outcomes compared to normal blood sugar levels. As a result, healthcare providers will often check an individual's glucose levels when ruling out a stroke.

People with diabetes are at a higher risk of having a stroke, which can cause brain tissue damage and lead to disability or death. Diabetes prevents the body from processing food properly, causing glucose (sugar) to build up in the blood. Over time, high glucose levels can damage blood vessels, increasing the chance of having a stroke.

While intensive glucose management after an acute ischemic stroke was thought to lead to better outcomes, recent studies have found that aggressive methods are not better than standard approaches. The Stroke Hyperglycemia Insulin Network Effort (SHINE) study, a large, multi-site clinical study, compared two commonly used strategies for glucose control in ischemic stroke patients. More than 1100 patients underwent intensive glucose management, which involved using intravenous insulin delivery to lower blood sugar levels, or standard glucose control using insulin shots. After 90 days, the patients were evaluated for outcomes, including disability, neurological function, and quality of life.

The results of the SHINE study suggested that both intensive and standard treatments were equally effective at helping patients recover from their strokes. About 20% of the patients showed favorable outcomes, regardless of the treatment method. Additionally, intense glucose therapy increased the risk of very low blood glucose (hypoglycemia) and required a higher level of care compared to standard treatment.

Therefore, intensive glucose management after acute ischemic stroke does not lead to better outcomes than standard approaches. While controlling blood sugar levels is important, especially for individuals with diabetes, the current evidence suggests that aggressive methods may not provide additional benefits and may even carry higher risks.

High blood sugar can increase fatty deposits or clots in blood vessels that may lead to stroke

High blood sugar can have a detrimental impact on the body, increasing the likelihood of a stroke. Diabetes, a condition that causes blood sugar to rise, is a key risk factor for strokes. People with diabetes are twice as likely to experience a stroke, which can lead to severe health issues and disabilities.

The link between diabetes and stroke lies in how the body manages blood glucose to produce energy. When we eat, food is broken down into glucose, which enters the bloodstream and travels to cells throughout the body. For glucose to enter these cells and provide energy, the body needs insulin, a hormone produced by the pancreas.

In Type 1 diabetes, the pancreas does not produce insulin. In Type 2 diabetes, the pancreas produces insufficient insulin, or the body's cells do not use insulin correctly. As a result, people with untreated diabetes have too much glucose in their blood, leaving their cells without enough energy. Over time, this excess blood glucose can lead to an increase in fatty deposits or clots in the blood vessels, heightening the risk of stroke.

High blood sugar levels can damage the body's blood vessels, making a stroke more likely. Adults with diabetes are 1.5 times more likely to experience a stroke than those without the condition. Additionally, they face twice the risk of dying from heart disease or stroke.

To prevent strokes, people with diabetes should manage their blood glucose, blood pressure, cholesterol, and weight. Maintaining a healthy weight, eating a nutritious diet, and getting enough sleep can help lower the chances of a stroke. Regularly checking blood glucose and blood pressure levels and seeking medical attention at the first sign of stroke symptoms are also crucial steps in stroke prevention.

Hyperglycaemia may result from known diabetes, metabolic syndrome, or stress response

Hyperglycaemia, or high levels of glucose, is a common occurrence in patients with acute ischemic stroke. It is associated with worse outcomes compared to normal blood sugar levels. High blood sugar can worsen stroke injuries, and it is more prominent in low to medium-income households.

Hyperglycaemia can be caused by known diabetes, metabolic syndrome, or a stress response. Diabetes mellitus is a condition that causes blood sugar to rise. People with diabetes are twice as likely to have a stroke as people without diabetes. This is because diabetes prevents the body from processing food properly, causing glucose to build up in the blood. Over time, high glucose levels can damage blood vessels, increasing the chance of having a stroke. Diabetes can also lead to other health problems that can cause a stroke, such as extra body weight, high blood pressure, and heart disease.

Metabolic syndrome, also known as insulin resistance syndrome, is a cluster of conditions that occur together and include increased blood pressure, high blood sugar levels, excess body fat around the waist, and abnormal cholesterol levels. These conditions can increase the risk of stroke.

Stress-induced hyperglycaemia can also occur in seriously ill patients who have recently had a stroke or those with a severe infection.
