There is a well-known correlation between diabetes and dementia. Exploring the relationship between the two conditions.
Insulin and Diabetes
The regulation of blood sugar is managed by insulin. Diabetes arises when the body either does not produce enough insulin or the cells become resistant to it, resulting in elevated blood sugar levels. Diabetes can be classified into two types:
- Type 1 diabetes – a condition present from birth where the immune system attacks cells that produce insulin.
- Type 2 diabetes – typically develops later in life when the body produces insufficient insulin or the cells become resistant to it, a condition known as insulin resistance.
Studies suggest that individuals with type 2 diabetes are at a higher risk of developing dementia. This risk increases with the duration and severity of the diabetes. However, having diabetes does not guarantee the development of dementia. Furthermore, severe fluctuations in blood sugar levels in type 1 diabetes can also increase the risk of dementia.
Preventing Dementia
Embarking on a healthy lifestyle can help lower the risk of dementia.
There are specific habits that have been proven to decrease the risk of dementia.
Engaging in regular physical exercise, maintaining a balanced diet rich in fruits and vegetables, staying socially active, challenging the brain with activities like puzzles or learning new skills, managing stress, getting enough quality sleep, and avoiding smoking and excessive alcohol consumption are all key factors in preventing dementia.
It’s never too late to start adopting these healthy habits to protect your cognitive health and reduce the risk of developing dementia in the future.
Managing Health as You Age
As one ages, the likelihood of developing diabetes and other health conditions increases. It is advisable to consult a general practitioner for health assessments.
A well-balanced diet can reduce the risk of type 2 diabetes. Consuming a variety of foods in appropriate proportions contributes to overall health. The NHS Eatwell guide offers suggestions for a balanced diet.
Risk of Dementia in Diabetics
Individuals with diabetes are at a heightened risk of developing dementia compared to those without diabetes, as evidenced by a review of 14 studies.

Diabetes is a serious condition characterized by the body’s inability to efficiently produce insulin, resulting in high blood sugar levels (hyperglycemia).
Persistent high blood sugar levels can lead to complications in the eyes, kidneys, nerves, heart, and increase the risk of stroke and heart disease. The incidence of diabetes continues to rise.
Type 1 Diabetes
Type 1 diabetes occurs when pancreatic cells stop producing insulin, leading to elevated blood sugar levels. Managing type 1 diabetes requires the essential use of insulin injections.
In addition to insulin injections, individuals with type 1 diabetes also need to monitor their blood sugar levels regularly. This can be done using a glucose meter to check blood sugar levels throughout the day. It is important for individuals with type 1 diabetes to maintain stable blood sugar levels to prevent complications such as hypoglycemia or hyperglycemia.
Diet and exercise also play a crucial role in managing type 1 diabetes. A balanced diet that includes carbohydrates, proteins, and fats can help regulate blood sugar levels. Regular physical activity can also improve insulin sensitivity and overall health.
Type 2 Diabetes
Type 2 diabetes is characterized by insufficient insulin production and insulin resistance. Approximately half of individuals with type 2 diabetes require insulin within 6-10 years of diagnosis.

Gestational Diabetes
Gestational diabetes affects 5-10% of pregnant women and often resolves after childbirth. Women with gestational diabetes face an increased risk of developing type 2 diabetes in the future.

Insulin Function
Insulin plays a crucial role in regulating blood glucose levels by transporting glucose to the cells for energy. In type 1 diabetes, the body does not produce insulin, necessitating regular insulin injections. Some individuals with type 2 diabetes may also require insulin therapy.

Insulin Injections
Individuals with type 1 diabetes typically administer insulin injections 4-5 times daily. Those with type 2 diabetes may also need insulin when diet, exercise, and oral medications are ineffective in controlling blood sugar levels.

Commencing insulin injections may seem daunting, but it is simpler than expected. Various devices are available to facilitate insulin delivery, such as pen needles and cannulas. Individuals requiring insulin typically experience improved well-being with its use.
If insulin therapy is necessary, healthcare providers can offer education and support, teaching about:
- the types and actions of insulin
- administering insulin injections
- rotating injection sites
- proper storage of insulin
- managing low blood sugar levels
- monitoring blood glucose levels and insulin doses
- adjusting insulin doses
Insulin dosages may need adjustments over time due to various factors, underscoring the importance of regular reviews.
When initiating insulin therapy, consulting a dietitian to learn about carbohydrates and insulin is essential.
For individuals with type 1 diabetes, matching insulin doses to food intake is critical. Insulin doses at mealtimes vary depending on the type of food consumed.
Basal and Background Insulins
Basal or background insulins provide a steady level of insulin throughout the day and night, helping to maintain stable blood sugar levels when fasting or between meals. These insulins are crucial for managing diabetes effectively.
Some key points about basal insulin:
- Basal insulins have a longer duration of action compared to rapid-acting insulins.
- They are typically taken once or twice a day, depending on the specific insulin type and individual needs.
- Basal insulins are not meant to address immediate rises in blood sugar levels after meals.
It’s important to work closely with a healthcare provider to determine the right basal insulin regimen for your diabetes management plan.
Insulin Delivery Devices
Syringes
Available in varying unit measurements and needle lengths. Insulin pens have become the preferred choice for most Australian adults due to their convenience.
Insulin Pens
Designed to accommodate specific insulin brands, either as disposable or reusable options.
Disposable pens are discarded once empty, while reusable pens require cartridge insertion.
Pen needles are disposable and come in different lengths and gauges.
Insulin Pump
Holds insulin and delivers it through tubing into the body. Only rapid-acting insulin is delivered through this pump.
Programmed to provide a constant insulin supply with additional manual doses for meals, mimicking the natural release of insulin.
Prior to considering an insulin pump, discussion with the diabetes healthcare team is recommended.
Private health insurance may cover the cost of insulin pumps for individuals with type 1 diabetes.
Insulin injection sites
Insulin is injected into the subcutaneous layer for absorption.
The abdomen absorbs insulin most rapidly, while the upper arms, buttocks, and thighs have slower absorption rates.
It is important to rotate injection sites to prevent lipodystrophy, a condition where fatty tissue under the skin becomes lumpy or depressed. By rotating injection sites, you can ensure that insulin is being absorbed effectively and prevent complications.
Some other common injection sites include the back of the arms, hips, and lower back. Consult with your healthcare provider to determine the best injection sites for you based on your individual needs and preferences.
Factors that speed insulin absorption
Variations in insulin absorption can affect blood glucose levels.
- Exercise can accelerate absorption rates.
- Elevated temperatures can also expedite absorption.
- Massaging the injection site can aid absorption.
- Avoid injecting into muscle to prevent rapid absorption.
- Proper hydration can help insulin absorption.
- Taking insulin before meals can lead to quicker absorption.
- Using smaller gauge needles can speed up absorption.
Factors that delay insulin absorption
Alter insulin absorption by utilizing different injection sites and avoiding cold insulin.
Disposal of used insulin syringes
Dispose of used syringes and other sharps in designated sharps containers.
Proper disposal protocols may vary by state.
Contact local organizations for guidance on disposal procedures.
Never throw used syringes in the regular trash or recycling bin to prevent accidental needlestick injuries.
Check with your local pharmacy or healthcare provider for disposal options or programs.
Insulin storage
Store insulin appropriately to maintain its efficacy.
- Unopened insulin should be stored in the refrigerator.
- Opened insulin can be stored at room temperature.
- Avoid exposure to extreme temperatures.
Utilize insulated carry bags for transporting insulin.
Insulin safety
Do not use insulin if it displays signs of damage or has expired.
Record your blood glucose levels and insulin doses
Maintain a record of blood glucose levels to facilitate adjustments in insulin dosages.
