The Connection Between Low Blood Sugar and Stroke: A Comprehensive Guide | low blood sugar and stroke
Introduction to Low Blood Sugar and Stroke
Low blood sugar, also known as hypoglycemia, occurs when the level of glucose in the blood falls below a certain threshold. According to the American Diabetes Association, a normal blood sugar level is between 70 and 140 milligrams per deciliter (mg/dL). Hypoglycemia can be caused by a variety of factors, including taking too much diabetes medication, skipping meals, or exercising too much. On the other hand, high blood sugar levels, or hyperglycemia, can also be harmful and increase the risk of stroke and other cardiovascular diseases.
A stroke occurs when the blood supply to the brain is interrupted, either due to a blockage or a rupture of the blood vessels. Diabetes is a major risk factor for stroke, as high blood sugar levels can damage the blood vessels and increase the risk of blockages. The Centers for Disease Control and Prevention (CDC) estimates that people with diabetes are two to four times more likely to have a stroke than those without diabetes.
The following table illustrates the normal range of blood sugar levels and the risks associated with low and high blood sugar levels:
| Blood Sugar Level (mg/dL) |
Risk |
| 70-140 |
Normal |
| <70 |
Hypoglycemia (low blood sugar) |
| >140 |
Hyperglycemia (high blood sugar) |
The Impact of Hypoglycemia on the Cardiovascular System
Hypoglycemia can have a significant impact on the cardiovascular system, increasing the risk of stroke and other cardiovascular diseases. When blood sugar levels fall too low, the body releases stress hormones, such as adrenaline and cortisol, to help raise blood sugar levels. These hormones can cause the heart to beat faster and increase blood pressure, which can be harmful to people with pre-existing heart conditions.
Hypoglycemia or Hyperglycemia Acquired Brain Injury - Brain and … The study compared two commonly used strategies for glucose control in ischemic stroke patients: intensive glucose management, which required the use of intravenous insulin to bring blood sugar levels down to 80-130 mg/dL, and standard glucose control, which used insulin shots to aim for blood sugar levels below 180 mg/dL. Blood Sugar Level Chart: What's Normal, Low, and High? - MedicineNet A stroke occurs when the flow of blood to the brain is blocked. It is a medical emergency, because blood carries oxygen, and brain cells begin to die within a few minutes without it.
In addition, hypoglycemia can cause a condition called hypoglycemic hemineglect, which can mimic stroke symptoms. Hypoglycemic hemineglect is a condition in which the brain ignores or neglects one side of the body, causing symptoms such as weakness, numbness, or paralysis on one side of the body. This condition can be mistaken for a stroke, making it essential to monitor blood sugar levels and respond quickly to hypoglycemic episodes.
Stroke and Diabetes: Connection, Risk, and Treatment
The connection between stroke and diabetes is complex and bidirectional. On one hand, diabetes increases the risk of stroke by damaging the blood vessels and increasing the risk of blockages. On the other hand, stroke can also increase the risk of developing diabetes, as the stress of a stroke can raise blood sugar levels and increase insulin resistance.
The treatment of stroke and diabetes involves a combination of lifestyle changes and medications. Lifestyle changes, such as eating a healthy diet, exercising regularly, and quitting smoking, can help manage blood sugar levels and reduce the risk of stroke. Medications, such as anticoagulants and antiplatelet agents, can help prevent blood clots and reduce the risk of stroke.
Heat stroke, a condition that occurs when the body temperature rises too high, can also have an impact on blood sugar levels. Heat stroke can cause dehydration, which can raise blood sugar levels and increase the risk of hyperglycemia. It is essential to stay hydrated and monitor blood sugar levels during hot weather or strenuous exercise.
Hypoglycemic hemineglect a stroke mimic - PMC - PubMed … Acute hypoglycemia may mimic acute ischemic stroke, but to our knowledge this has never been reported as transient hemineglect syndrome.

Stroke and Diabetes: Connection, Risk, Treatment - Verywell Health The main clinical manifestation of type 2 diabetes is elevated blood glucose levels. The link between diabetes and CVD is well known, so it is logical to assume that elevated glucose levels may be important, to some extent, in the context of heart and vascular disease. ... mediated by non-enzymatic glycosylation of low-density lipoprotein ...
Hypoglycemia and Stroke: A Complex Relationship
The relationship between hypoglycemia and stroke is complex and multifaceted. Severe hypoglycemia can masquerade as cerebellar stroke, causing symptoms such as dizziness, weakness, and loss of coordination. In addition, hypoglycemia can increase the risk of stroke by damaging the blood vessels and increasing the risk of blockages.
Diagnosing and treating hypoglycemia in patients with stroke can be challenging, as the symptoms of hypoglycemia can be mistaken for stroke symptoms. It is essential to monitor blood sugar levels closely and respond quickly to hypoglycemic episodes to prevent long-term damage to the brain and other organs.
Managing Low Blood Sugar and Preventing Stroke
Managing low blood sugar levels and preventing stroke involves a combination of lifestyle changes and medications. The following foods and drinks can help raise blood sugar levels quickly:
- Fruit juice, such as orange or apple juice
- Regular soda, such as cola or lemon-lime soda
- Candy, such as glucose tablets or hard candy
- Crackers with cheese or peanut butter
In addition to these foods and drinks, lifestyle changes, such as eating a healthy diet, exercising regularly, and quitting smoking, can help manage blood sugar levels and reduce the risk of stroke. It is also essential to monitor blood sugar levels closely and respond quickly to hypoglycemic episodes to prevent long-term damage to the brain and other organs.
Stroke and Diabetes: Connection, Risk, Treatment - Verywell Health NIH-funded study points to standard treatment of blood sugar levels. 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. Animal studies also pointed to an effect of high blood sugar in worsening stroke injury. Understanding the impact of hypoglycemia on the cardiovascular system Low blood sugar can cause symptoms similar to a stroke, such as dizziness, shakiness, irregular heartbeat or severe headache. High blood sugar, on the other hand, can cause blurred vision, weakness, severe headache and feeling out of it, making it difficult to distinguish high blood sugar from a stroke.
