What Is Diabetes?

Diabetes is a chronic condition that affects how the body processes glucose, a vital source of energy. It occurs when the body either does not produce enough insulin or cannot use it effectively, leading to high blood sugar levels (hyperglycemia). If left untreated, diabetes can result in serious complications, including heart disease, nerve damage, and kidney problems.
Types of Diabetes
There are three main types of diabetes: type 1, type 2, and gestational diabetes. Each type has distinct causes and symptoms.
Type 1 diabetes
Type 1 diabetes is an autoimmune disorder in which the body’s immune system attacks and destroys the insulin-producing beta cells in the pancreas.
Causes
The exact cause of type 1 diabetes remains unknown, but several factors are believed to contribute to this condition:
- Genetics: A family history of type 1 diabetes increases the risk of developing the condition.
- Environmental triggers: Certain viruses or environmental factors may initiate the immune system’s attack on the pancreas.
- Autoantibodies: High levels of specific antibodies in the blood indicate the immune system is attacking beta cells.
Symptoms
Type 1 diabetes may present with varying symptoms. The classic symptoms of type 1 diabetes are related to high sugar levels and low insulin levels – these include:
- Excessive thirst
- Frequent urination
- Unintentional weight loss
- Fatigue
- Blurred vision
- Increased hunger
- Slow-healing wounds or frequent infections
A serious complication, called diabetic ketoacidosis (DKA), can also develop and requires immediate medical attention. Symptoms of DKA include:
- Nausea and vomiting
- Abdominal pain
- Rapid breathing
- Confusion or even coma
Type 2 diabetes
Type 2 diabetes occurs when the body becomes insulin resistant, meaning cells do not respond effectively to insulin. Over time, the pancreas cannot produce enough insulin to keep blood glucose levels under control.
Causes
The main causes and risk factors of type 2 diabetes include:
- Genetic factors: A family history of type 2 diabetes and genetic factors, particularly in Asians, increase the risk.
- Lifestyle factors: Poor dietary habits, especially diets high in refined sugars and unhealthy fats, contribute to insulin resistance.
- Physical inactivity: A sedentary lifestyle is a significant factor in the development of type 2 diabetes.
- Excess body weight: Obesity, particularly abdominal fat, increases the risk of developing insulin resistance.
- Other risk factors: Previous gestational diabetes, smoking, and excessive alcohol consumption also increase the risk of type 2 diabetes.
Symptoms
Type 2 diabetes usually develops gradually and may not cause noticeable symptoms, especially in the early stages. Some individuals may experience symptoms of high sugar levels which include:
- Frequent urination
- Increased thirst
- Blurred vision
Gestational diabetes
Women without a prior history of diabetes can develop gestational diabetes during pregnancy. This condition affects 2–10% of pregnancies and typically resolves after childbirth. It occurs when pregnancy-related hormonal changes make the body resistant to insulin, leading to elevated blood sugar levels.
Causes
The exact cause of gestational diabetes remains unclear, but excess weight before pregnancy is often a contributing factor. During pregnancy, hormonal changes make it harder for the body to process blood sugar efficiently, leading to higher blood sugar levels.
Symptoms
Gestational diabetes often does not cause noticeable symptoms, but some women may experience increased thirst and more frequent urination.

How Is Diabetes Diagnosed?
Your doctor will review your medical history, lifestyle, and family history of diabetes. They will ask about symptoms that may indicate high blood sugar levels and assess the duration and severity of these issues.
Next, several blood tests will be used to assess blood glucose levels and help differentiate between type 1, type 2, and prediabetes.
This test measures your blood sugar after an overnight fast.
A random blood sugar test measures glucose levels at any time of the day, allowing quick assessment of whether you have high blood glucose.
The HbA1C test reflects your average blood sugar levels over the past 3 months, offering a long-term view of glucose control.
This test measures your blood sugar levels before and after drinking a glucose solution, helping to diagnose conditions like Type 2 diabetes and gestational diabetes.
Tests to measure antibody levels, insulin levels etc. depending on the doctor’s assessment.

FAQs About Diabetes
How do I know if I have diabetes?
Diabetes symptoms can vary across individuals but symptoms of high blood sugar levels may include:
- Weight loss
- Increased thirst
- Frequent urination
- Fatigue
- Breath odour changes
- Vision issues
These symptoms often develop gradually, making them easy to overlook. If you suspect that you may have diabetes, we recommend taking a simple blood test to check your blood sugar levels. Book a consultation today to find the right test for you.
Is diabetes hereditary?
Diabetes is not directly inherited, but genetic predisposition plays a role in its development. In type 1 diabetes, multiple genes interact with environmental factors, influencing the risk of developing diabetes.
Type 2 diabetes has a stronger hereditary link but is still influenced by lifestyle and environmental factors. Lastly, gestational diabetes has both genetic and environmental causes.
Can diabetes be cured or reversed?
It depends on the type of diabetes you have, the stage of your condition, and your overall health. For some, achieving remission—a state where blood sugar levels are well-controlled without the need for medication—may be possible. Speak to our diabetes specialist for advice on your condition.
Are there complications from leaving diabetes untreated?
Leaving diabetes untreated can lead to severe and irreversible complications. High blood sugar levels can damage blood vessels, nerves, and organs over time, increasing the risk of multiple health issues. Many complications develop gradually and may not show symptoms until significant damage has occurred.
Possible complications of untreated diabetes include:
- Heart disease and stroke
- Kidney disease
- Vision loss (e.g. diabetic retinopathy, cataracts, glaucoma)
- Nerve damage (e.g. neuropathy)
- Slow-healing wounds and higher infection risks
- Ulcers/amputations of feet
- Cognitive decline (e.g. dementia, Alzheimer’s disease, memory problems)
Early detection and proper management can help prevent or slow down these complications.
Can alternative or traditional therapies help manage diabetes?
Many people explore alternative or traditional therapies as part of their health journey. While some evidence suggests the potential benefits of these therapies for diabetes management, it is essential to approach them with caution and discuss their use with your doctor.
