Blood glucose, also referred to as blood sugar, is the primary sugar found in your bloodstream and serves as a source of energy. It is derived from the food you consume, and your body converts it into glucose. The pancreas releases insulin when blood glucose levels increase, assisting cells in utilizing glucose for energy.
What is diabetes?
Diabetes develops when blood glucose levels become too high, resulting in complications. It is essential for individuals with diabetes to maintain blood glucose within the desired range.
What are blood glucose targets?
Individuals with diabetes typically aim for blood glucose levels between 80-130 mg/dL before a meal and less than 180 mg/dL two hours after. These targets may vary depending on age and other health factors.
When and how should I check my blood glucose?
Regular monitoring of blood glucose levels is vital for individuals with diabetes. This is commonly achieved through the use of a blood glucose meter at home or continuous glucose monitoring systems.
What happens if my blood glucose level becomes too high?
Elevated blood glucose levels, known as hyperglycemia, can lead to symptoms like thirst, fatigue, frequent urination, and blurred vision. Managing high blood glucose levels is crucial through a combination of diet, exercise, and medication.
What happens if my blood glucose level becomes too low?
Low blood glucose, or hypoglycemia, can be dangerous and requires immediate attention. Symptoms may include shaking, sweating, and hunger. While common in individuals with diabetes, hypoglycemia can also occur in those without diabetes due to certain health conditions.
Diabetes is a condition characterized by high blood glucose levels due to insufficient insulin production or utilization. Proper management of diabetes is essential to prevent complications and reduce the risk of related health issues.
What are the different types of diabetes?
The most prevalent types of diabetes include type 1, type 2, and gestational diabetes.
Type 1 diabetes
Type 1 diabetes is defined by a lack of insulin production, necessitating daily insulin injections for management.
Type 2 diabetes
Type 2 diabetes occurs as a result of improper insulin utilization and is often associated with factors like obesity and family history. Lifestyle changes can help prevent or manage type 2 diabetes.
Gestational diabetes
Gestational diabetes emerges during pregnancy and may resolve post-childbirth. However, it raises the risk of developing type 2 diabetes later in life.
Prediabetes
Prediabetes is a precursor to type 2 diabetes, characterized by elevated blood glucose levels. Effective management of prediabetes can lower the risk of developing type 2 diabetes and heart disease.
Other types of diabetes
Monogenic diabetes and other rare forms of diabetes may be attributed to genetic factors or conditions affecting the pancreas.
How common are diabetes and prediabetes?
As of 2019, diabetes affected a significant portion of the U.S. population, with type 2 diabetes being the most common form. Prediabetes also poses a substantial health risk.
In the United States, approximately 34.2 million people have diabetes, which is about 10.5% of the population. Type 2 diabetes accounts for around 90-95% of all diagnosed cases of diabetes.
Moreover, it is estimated that 88 million American adults have prediabetes, which increases their risk of developing type 2 diabetes, heart disease, and stroke.
What other health problems can people with diabetes develop?
Maintaining optimal blood glucose levels is crucial in preventing diabetes-related complications involving the heart, kidneys, eyes, and feet. Lifestyle adjustments and regular monitoring can mitigate the risk of future health issues.

Diabetes explained
Diabetes is a prevalent condition affecting individuals of all ages in the UK, resulting in elevated blood sugar levels. Glucose, obtained from carbohydrates in food like bread, potatoes, fruits, and sugary items, serves as the primary source of energy for the body.
Glucose is transported through the blood to cells for energy production. Insulin, produced by the pancreas, directs cells to absorb glucose when levels rise. In diabetes, this process is disrupted, leading to artery damage and an increased risk of heart disease.

Types of diabetes
There are two primary types of diabetes – type 1 and type 2. Type 1 diabetes is characterized by the body’s failure to produce insulin due to immune system attacks, while type 2 diabetes results from insufficient or ineffective insulin in the body.
Prediabetes occurs when blood sugar levels are elevated but not at diabetic levels, and gestational diabetes can manifest in pregnant women but usually resolves postpartum.
Type 1 diabetes is typically diagnosed in children and young adults, while type 2 diabetes is more common in adults, although it is now increasingly being diagnosed in children and adolescents due to rising obesity rates.
Managing diabetes involves monitoring blood sugar levels, eating a healthy diet, exercising regularly, and taking medication as prescribed by a healthcare provider. It is important for individuals with diabetes to work closely with their healthcare team to prevent complications and live a healthy life.
Causes of diabetes
The cause of type 1 diabetes remains unknown, while type 2 diabetes is associated with issues related to insulin production or utilization. Risk factors include sedentary lifestyle, obesity, family history, age, and ethnicity.
Other contributing factors to diabetes include high blood pressure, high cholesterol levels, and gestational diabetes during pregnancy. Additionally, certain medications, such as corticosteroids and antipsychotic drugs, can increase the risk of developing diabetes.
Diabetes and your heart
Both types of diabetes can lead to the accumulation of glucose in the blood, harming arteries and increasing the risk of heart attack and stroke.
Diabetes symptoms
Symptoms of diabetes encompass blurred vision, fatigue, excessive thirst, unintentional weight loss, fruity breath, frequent urination, and slow wound healing. Early diagnosis of diabetes can be facilitated by testing blood sugar levels.
If experiencing symptoms, seek medical advice to receive a proper diagnosis and treatment. Emotional support is available via the Heart Helpline and online communities.
Diabetes diagnosis
Diabetes diagnosis involves checking blood sugar levels, with the HbA1c test offering a reliable measure over 2-3 months. Treatments vary for type 1 and type 2 diabetes, including insulin, medication, exercise, and dietary adjustments.
It is crucial for individuals diagnosed with diabetes to regularly monitor their blood sugar levels to manage their condition effectively. This can be done through daily blood glucose testing using a glucose meter.
In addition to medical treatments, lifestyle changes such as maintaining a healthy diet low in sugar and saturated fats, regular physical activity, and managing stress are also important in managing diabetes.
Diabetes treatment
Maintaining a balanced diet and engaging in regular exercise are essential for effective diabetes management, aiding in controlling blood sugar levels and reducing the risk of complications.
Are you worried about your symptoms?
Your healthcare provider can offer guidance on food choices like fruits, vegetables, whole grains, lean protein, and low-fat dairy to support diabetes management.
Eating with diabetes
Physical activity plays a crucial role in managing blood sugar levels and lowering the risk of heart disease. Aim for approximately two and a half hours of exercise per week, incorporating activities such as swimming and cycling.
- walking with your dog
- playing with a frisbee in the park
- pushing a lawn mower or hoovering.
