What is a Dangerous Blood Sugar Level?
A dangerous blood sugar level occurs when the glucose concentration in the bloodstream is either too high (hyperglycemia) or too low (hypoglycemia).
Dangerous blood sugar levels can vary depending on individual factors and the situation.
Both conditions can lead to severe health complications if not addressed promptly.
However, generally speaking, the following glucose levels are considered dangerous.
Hyperglycemia (High Blood Sugar)
High blood sugar levels can occur when the body doesn’t produce enough insulin or cannot use it effectively.
Prolonged hyperglycemia can damage blood vessels, nerves, and various organs, leading to an increased risk of heart disease, stroke, kidney failure, vision problems, and nerve damage.
Fasting Blood Glucose: Higher than 130 mg/dL (7.2 mmol/L) for people with diabetes
Postprandial (after a meal) Blood Glucose: Higher than 180 mg/dL (10 mmol/L) for people with diabetes
Blood sugar levels consistently above these thresholds indicate poor glycemic control and an increased risk of complications.
In extreme cases, untreated hyperglycemia can result in diabetic ketoacidosis (DKA) in type 1 diabetes or hyperosmolar hyperglycemic state (HHS) in type 2 diabetes, both of which are life-threatening emergencies.
Hypoglycemia
Low blood sugar levels can be caused by taking too much insulin, skipping meals, exercising intensely without adjusting food or medication, or consuming alcohol.
Blood Glucose: Lower than 70 mg/dL (3.9 mmol/L) for both people with and without diabetes
Severe hypoglycemia typically occurs when blood sugar levels drop below 54 mg/dL (3.0 mmol/L), which requires immediate intervention to prevent serious consequences.
Hypoglycemia can lead to symptoms like dizziness, confusion, weakness, and even loss of consciousness or seizures in severe cases.
Persistent or recurrent hypoglycemia can also harm the brain and nervous system over time.
Keeping blood sugar levels under control is essential to prevent these complications and maintain overall health.
Proper management involves regular monitoring, adhering to prescribed medications, maintaining a balanced diet, engaging in regular physical activity, and adjusting treatment plans as needed under the guidance of a qualified diabetologist in Pune.
Different Types of Diabetes and Their Effects on Blood Sugar Levels
Diabetes is a chronic health condition characterised by the body’s inability to regulate blood sugar levels effectively.
There are two main types of diabetes, along with some less common forms. Each type has a different impact on blood sugar levels.
Type 1 Diabetes
This form of diabetes, or juvenile diabetes, occurs when the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas.
As a result, the body produces little or no insulin, leading to high blood sugar levels.
People with type 1 diabetes need insulin injections or insulin pumps to manage their glucose levels.
Type 2 Diabetes
This is the most common type of diabetes, and it develops when the body becomes resistant to insulin or the pancreas cannot produce enough insulin to maintain normal blood sugar levels.
Type 2 diabetes can be influenced by factors such as genetics, age, obesity, and lifestyle choices.
Management of type 2 diabetes typically involves lifestyle changes, oral medications, and sometimes insulin therapy, depending on the severity.
Gestational Diabetes
This form of diabetes occurs during pregnancy and is characterised by high blood sugar levels in pregnant women who previously did not have diabetes.
It typically resolves after giving birth, but it increases the risk of developing type 2 diabetes later in life for both the mother and the child.
Gestational diabetes is usually managed through dietary changes, exercise, and, in some cases, insulin therapy.
Other Types
Some less common forms of diabetes include monogenic diabetes (caused by a single gene mutation) and secondary diabetes (resulting from other medical conditions or treatments).
Each type of diabetes affects blood sugar levels differently, and managing them requires tailored approaches that address the specific underlying causes and individual needs.
Regular monitoring and appropriate interventions are crucial to prevent complications and maintain overall health.
Blood Sugar & Its Importance in Body
Blood sugar, also known as glucose, is a simple sugar that serves as our bodies’ primary source of energy. It is derived from food, particularly carbohydrates, broken down into glucose during digestion.
Once in the bloodstream, glucose is transported to cells throughout the body, which is used as fuel for various cellular processes.
The importance of blood sugar in the body cannot be overstated. Glucose is critical for providing energy to the brain, muscles, and other organs and ensuring their effective function.
Moreover, it is vital in maintaining the body’s overall homeostasis – the delicate balance that keeps our internal environment stable and supports optimal health.
