Overview
Diabetes encompasses a group of diseases characterised by issues with the hormone insulin. Insulin is essential for regulating blood sugar levels. The lack of insulin production or the body’s inability to use insulin effectively leads to elevated blood sugar levels, causing various health complications over time. Currently, there is no cure for diabetes, but it can be managed through lifestyle changes, medication, and regular monitoring.
Type 1 diabetes is an autoimmune condition where the body’s immune system attacks and destroys insulin-producing cells in the pancreas. This type of diabetes typically develops in childhood or adolescence, but it can occur at any age. People with type 1 diabetes require lifelong insulin therapy to manage their blood sugar levels.
Type 2 diabetes is a chronic condition that affects the way the body processes blood sugar (glucose). It usually develops in adults over the age of 45, but it is increasingly seen in younger age groups, including children, adolescents, and young adults. Type 2 diabetes is associated with obesity, physical inactivity, and poor diet. It can often be managed with lifestyle changes, but medication or insulin therapy may also be necessary.
Gestational diabetes develops during pregnancy and usually disappears after giving birth. However, it increases the risk of developing type 2 diabetes later in life for both the mother and the child. Women with gestational diabetes need to carefully manage their blood sugar levels to avoid complications during pregnancy and delivery.
Diabetes insipidus is a rare condition characterised by excessive thirst and the production of large amounts of dilute urine. Unlike diabetes mellitus, which involves issues with insulin and blood sugar levels, diabetes insipidus is related to the body’s inability to properly balance fluid levels. This imbalance is usually due to a problem with the hormone vasopressin, which regulates kidney function. There are two main types:
Gestagenic diabetes insipidus, also known as gestational diabetes insipidus, is a rare disorder that occurs during pregnancy, typically in the third trimester. It is characterised by excessive thirst and urination, similar to other forms of diabetes insipidus. This condition is caused by the destruction of vasopressin by an enzyme produced by the placenta. It usually resolves after childbirth, but careful management is necessary during pregnancy to ensure the health and safety of both mother and baby.
The warning signs of diabetes can be so mild that they may go unnoticed, especially in type 2 diabetes. Common symptoms include:
> Frequent urination
> Excessive thirst
> Unexplained weight loss
> Fatigue
> Blurred vision
> Slow-healing sores
Diabetes can be diagnosed through several tests, including:
The OGTT evaluates how well your body processes glucose and is particularly used for diagnosing gestational diabetes.
The HbA1c test provides an average blood sugar level over the past two to three months, indicating how well diabetes is being managed.

According to the Australian Institute of Health and Welfare (AIHW):
Diabetes can affect anyone, but certain factors increase the likelihood of developing this condition. Understanding the risk factors for each type of diabetes can help with early detection and management. Here’s a closer look at the risk factors associated with type 1 diabetes, prediabetes, type 2 diabetes, and gestational diabetes.
Type 1 diabetes is thought to be caused by an autoimmune reaction where the body mistakenly attacks insulin-producing cells in the pancreas. While the exact cause is unknown, several risk factors are associated with an increased likelihood of developing type 1 diabetes:
Prediabetes and type 2 diabetes share nearly identical risk factors. If you have prediabetes, you are at a higher risk of developing type 2 diabetes. Key risk factors for both conditions include:
Overweight or Obesity: Excess weight, especially around the abdomen, increases the risk.
Gestational diabetes occurs during pregnancy and usually goes away after childbirth, but it can pose risks for both the mother and child. The risk factors for gestational diabetes include:
Previous Gestational Diabetes: Women who had gestational diabetes in a previous pregnancy are at higher risk.
While gestational diabetes typically resolves after birth, having it increases the mother’s risk of developing type 2 diabetes later in life. Additionally, the baby is more likely to experience obesity as a child or teen and to develop type 2 diabetes in the future.
Understanding these risk factors can help in taking proactive steps towards preventing or managing diabetes effectively.
Diabetes, if left unmanaged, can lead to a range of serious health complications that can affect various parts of the body. These complications can develop over time and significantly impact the quality of life. Understanding these potential complications is crucial for effective diabetes management and prevention.
Cardiovascular Disease
People with diabetes are at a higher risk of developing cardiovascular diseases, including coronary artery disease, heart attack, stroke, and hypertension. High blood sugar levels can damage blood vessels and the nerves that control the heart, increasing the risk of these conditions.
Nerve Damage (Neuropathy)
High blood sugar levels can cause nerve damage, known as diabetic neuropathy. This can lead to tingling, numbness, pain, or weakness in the hands and feet. Severe neuropathy can affect the digestive system, urinary tract, and cardiovascular system, leading to additional health problems.
Kidney Damage (Nephropathy)
Diabetes can damage the kidneys’ filtering system, leading to diabetic nephropathy. Over time, this can result in kidney failure or end-stage kidney disease, requiring dialysis or a kidney transplant.
Eye Damage (Retinopathy)
Diabetic retinopathy occurs when high blood sugar levels damage the blood vessels in the retina, potentially leading to blindness. Diabetes also increases the risk of other serious vision conditions, such as cataracts and glaucoma.
Foot Problems
Diabetes can cause poor blood flow and nerve damage in the feet, leading to a higher risk of various foot problems. These include infections, ulcers, and, in severe cases, the need for amputation. Regular foot care is essential to prevent serious complications.
Skin Conditions
People with diabetes are more prone to skin problems, including bacterial and fungal infections. Proper skin care and maintaining blood sugar levels can help prevent these issues.
Hearing Impairment
Diabetes can damage the blood vessels and nerves in the ears, leading to hearing problems. Hearing impairment is more common in people with diabetes compared to those without the condition.
Alzheimer’s Disease
Type 2 diabetes may increase the risk of Alzheimer’s disease and other forms of dementia. The exact relationship between diabetes and cognitive decline is still being studied, but high blood sugar levels, insulin resistance, and inflammation are believed to play a role.
Managing diabetes effectively through medication, lifestyle changes, and regular monitoring can help reduce the risk of these complications. It is essential to work closely with our Endocrinologists at ISMC to create and follow a comprehensive diabetes management plan.
Preventing diabetes, particularly type 2 diabetes, involves making proactive lifestyle changes and maintaining regular health check-ups. These measures can significantly reduce the risk of developing diabetes and help manage the condition for those already diagnosed.
Here’s how you can take steps to prevent diabetes:
A balanced diet is crucial for preventing type 2 diabetes. Focus on incorporating a variety of nutrient-rich foods, including:
Fruits and Vegetables: Aim for a colourful mix of fruits and vegetables to ensure a range of nutrients.
Avoiding excessive consumption of sugar and processed foods can help maintain a healthy weight and reduce the risk of diabetes.
Physical activity is essential for diabetes prevention. Regular exercise helps maintain a healthy weight, improves insulin sensitivity, and lowers blood sugar levels. Aim for:
Maintaining a healthy weight is one of the most effective ways to prevent type 2 diabetes. Even a modest weight loss of 5-10% of your body weight can significantly reduce your risk. Focus on:
Regular check-ups with your healthcare provider are vital for early detection and prevention of diabetes. These visits can help you:
Smoking increases the risk of type 2 diabetes and its complications. If you smoke, seek resources and support to help you quit.
Excessive alcohol intake can lead to weight gain and increase the risk of type 2 diabetes. If you choose to drink, do so in moderation.
Chronic stress can affect your blood sugar levels and overall health. Practice stress-reducing techniques such as mindfulness, meditation, yoga, or engaging in hobbies you enjoy.
Educate yourself about diabetes and its risk factors. Knowledge empowers you to make informed decisions about your health and adopt preventive measures effectively.
By implementing these preventive measures, you can significantly reduce your risk of developing type 2 diabetes and maintain a healthier, more active lifestyle. Regular monitoring and proactive management are key to preventing diabetes and its associated complications.
