Diabetes is a serious medical condition that occurs when the body is unable to properly regulate blood sugar levels. There are two main types of diabetes: type 1, which is usually diagnosed in childhood, and type 2, which is more common in adults and is often linked to lifestyle factors such as diet and activity levels.
If left untreated or poorly managed, diabetes can lead to a range of complications, including nerve damage, kidney problems, vision loss, and foot ulcers. It can also significantly increase the risk of heart disease, stroke, and other cardiovascular issues.
Managing diabetes involves monitoring blood sugar levels, following a healthy diet, exercising regularly, and taking medication as prescribed by a healthcare provider. With proper management, people with diabetes can live long, healthy lives and reduce their risk of complications.
The Impact of Diabetes
Diabetes affects individuals of all ages by causing elevated blood sugar levels. Normally, glucose from food serves as the body’s primary energy source and is transported through the bloodstream to cells for energy production facilitated by insulin. However, in cases of diabetes, issues with insulin prevent the proper absorption of glucose, resulting in potential damage.
Diabetes can lead to a variety of complications, including heart disease, stroke, kidney disease, and nerve damage. It is important for individuals with diabetes to manage their condition carefully through proper diet, exercise, medication, and regular monitoring of blood sugar levels.

Understanding the Types of Diabetes
There are two main types of diabetes: type 1, characterized by insufficient insulin production by the body, and type 2, where insulin is either inadequate or utilized poorly. Prediabetes refers to elevated blood sugar levels that are below the threshold for diabetes diagnosis, while gestational diabetes occurs during pregnancy.
Causes and Risk Factors
The exact cause of type 1 diabetes remains unknown, while type 2 diabetes is often the result of insulin-related issues. Risk factors for type 2 diabetes include physical inactivity, obesity, age, and ethnicity.
Impact on Health
Diabetes contributes to the accumulation of glucose on red blood cells, leading to arterial damage and an increased risk of heart attack and stroke. This increased risk is due to the fact that high levels of glucose in the blood can cause inflammation and damage to the walls of blood vessels, making them more prone to blockages and clots.
Recognizing Diabetes Symptoms
Common symptoms of diabetes include blurry vision, fatigue, excessive thirst, weight loss, fruity breath, frequent urination, and slow wound healing. Early detection and treatment are crucial for managing the condition effectively.
Take Action
If you are experiencing symptoms of diabetes, it is important to get checked. Understanding your condition, treatment plan, and seeking support from healthcare professionals and the community are essential steps.
Managing Diabetes
Once diagnosed with diabetes, it is important to work closely with your healthcare team to develop a personalized treatment plan. This may include monitoring blood sugar levels, taking medications as prescribed, making healthy lifestyle choices such as eating a balanced diet and exercising regularly, and managing stress.

Type 1 diabetes is linked to autoimmune responses, with identified risk factors including family history and age.
In the US, individuals of White descent have a higher susceptibility to type 1 diabetes.
Type 2 diabetes, on the other hand, is primarily linked to lifestyle factors such as poor diet and lack of exercise. It is more common in adults but is increasingly being diagnosed in children due to rising obesity rates.
Risk Factors for Diabetes
Risk factors for prediabetes and type 2 diabetes encompass weight, age, family history, physical activity level, NAFLD, history of gestational diabetes, and ethnicity.
Factors Influencing Gestational Diabetes
Risk factors for gestational diabetes include prior gestational diabetes history, high birth weight babies, weight, age, family history, PCOS, and ethnicity.
Women who have had gestational diabetes in previous pregnancies are at a higher risk of developing it again. Babies born weighing over 9 pounds are also associated with an increased risk. Maternal weight plays a significant role, with obesity increasing the likelihood of developing gestational diabetes.
Advanced maternal age, typically over 35, is another risk factor for gestational diabetes. Family history of diabetes, particularly in first-degree relatives, can also increase the risk. Women with Polycystic Ovary Syndrome (PCOS) have a higher likelihood of developing gestational diabetes.
Furthermore, ethnicity plays a role in the risk of gestational diabetes, with women of Hispanic, African American, Native American, South or East Asian, and Pacific Islander descent being more susceptible to the condition.
Reducing Diabetes Risk
Lower the risk of prediabetes, type 2 diabetes, or gestational diabetes by increasing physical activity, maintaining a healthy diet, and achieving weight loss goals.

Eating a balanced diet rich in fruits, vegetables, whole grains, and lean protein can help maintain healthy blood sugar levels and reduce the risk of developing diabetes.
Regular Exercise
Engaging in regular physical activity, such as walking, cycling, or swimming, can help improve insulin sensitivity and reduce the risk of type 2 diabetes. Aim for at least 150 minutes of moderate exercise per week.
Monitor Blood Sugar Levels
Regular monitoring of blood sugar levels can help identify any changes early on and allow for prompt intervention to prevent the development of diabetes.
Manage Stress
Chronic stress can contribute to insulin resistance and increase the risk of diabetes. Practice stress-reducing techniques, such as meditation, yoga, or deep breathing exercises, to help manage stress levels.
Effective Treatment Approaches
Treatment strategies for diabetes are dependent on the type of diabetes and may include insulin therapy, lifestyle changes, and medication.
Potential Complications
Diabetes can lead to various health concerns such as heart problems, kidney issues, nerve damage, foot complications, vision impairments, and gum disease.
Complications can develop over time and are linked to elevated blood sugar levels. Monitoring and maintaining blood glucose levels within the target range can mitigate the risk of complications.
Diabetes is a chronic condition that arises when the body either produces insufficient insulin or cannot effectively utilize the insulin it generates. Insulin is vital in regulating blood glucose levels, and uncontrolled diabetes often results in hyperglycaemia, causing significant harm to various body systems, particularly nerves and blood vessels.
In 2022, 14% of adults aged 18 and above were living with diabetes, reflecting a notable increase from 7% in 1990. Additionally, more than half of adults over 30 living with diabetes were not undergoing treatment in 2022, with treatment coverage being lowest in low- and middle-income nations.
In 2021, diabetes directly led to 1.6 million fatalities, with 47% of these deaths occurring before the age of 70. Diabetes also contributed to 530,000 deaths from kidney disease and approximately 11% of cardiovascular-related deaths.
Mortality rates from diabetes have been on the rise since 2000. In contrast, the likelihood of dying from major noncommunicable diseases between the ages of 30 and 70 dropped by 20% globally between 2000 and 2019.
Recognizing Diabetic Symptoms
Symptoms of diabetes can manifest suddenly, with those of type 2 diabetes often being mild and taking years to manifest fully.
Common symptoms of diabetes include thirst, frequent urination, blurred vision, fatigue, and unintentional weight loss.
Over time, diabetes can cause damage to the heart, eyes, kidneys, and nerves, increasing the risk of health complications, such as heart attacks, strokes, and kidney failure.
Understanding Type 1 Diabetes
Type 1 diabetes is an autoimmune condition in which the immune system attacks and destroys the insulin-producing beta cells in the pancreas. This results in the body’s inability to produce insulin, a hormone necessary for regulating blood sugar levels. As a result, individuals with type 1 diabetes must rely on daily insulin injections or insulin pump therapy to manage their blood sugar levels.
Type 1 diabetes is typically diagnosed in children and young adults, although it can develop at any age. Symptoms of type 1 diabetes may include increased thirst, frequent urination, extreme hunger, unexplained weight loss, and fatigue.
While the exact cause of type 1 diabetes is still unknown, researchers believe that a combination of genetic and environmental factors may play a role in its development. There is currently no known way to prevent type 1 diabetes, and it is not related to lifestyle factors such as diet or exercise.
Managing type 1 diabetes requires a lifelong commitment to monitoring blood sugar levels, following a healthy meal plan, engaging in regular physical activity, and taking insulin as prescribed by a healthcare provider. With proper management, individuals with type 1 diabetes can live long, healthy lives.
Uncovering Type 2 Diabetes
Type 2 diabetes impacts how the body utilizes sugar for energy, hindered insulin function resulting in elevated blood sugar levels if left untreated.
Over time, type 2 diabetes can lead to severe bodily harm, especially affecting nerves and blood vessels.
Type 2 diabetes is largely preventable, with contributing factors including excess weight, inadequate physical activity, and genetic predisposition.
Early detection is vital in preventing severe consequences of type 2 diabetes. Regular health check-ups and blood tests are crucial for early diabetes detection.
Symptoms of type 2 diabetes may be subtle and develop over several years. They may share similarities with type 1 diabetes symptoms but are typically less pronounced.
More than 95% of individuals with diabetes have type 2 diabetes, which was previously termed non-insulin dependent or adult-onset diabetes. While traditionally seen in adults, type 2 diabetes is increasingly affecting children nowadays.
Diabetes Risks and Precautions
Gestational diabetes is a condition where blood glucose levels are elevated during pregnancy, but not high enough to be classified as diabetes. It poses risks for both mother and child.
Women with gestational diabetes have an increased likelihood of experiencing complications during pregnancy and delivery. Furthermore, they and their offspring have a higher risk of developing type 2 diabetes in the future.
The diagnosis of gestational diabetes is made through screening tests done during pregnancy, rather than based on symptoms.
Impaired glucose tolerance and impaired fasting glycaemia
Impaired glucose tolerance (IGT) and impaired fasting glycaemia (IFG) are intermediary stages between normal glucose levels and diabetes. Individuals with IGT or IFG have a heightened risk of progressing to type 2 diabetes, although it is not certain.
Prevention
The most effective way to delay or prevent the onset of type 2 diabetes is through lifestyle modifications.
To reduce the risk of type 2 diabetes and its complications, individuals should:
- Maintain a healthy weight
- Engage in regular physical activity for at least 150 minutes per week
- Adopt a nutritious diet low in sugar and saturated fats
- Avoid smoking
Diagnosis and treatment
Early detection of diabetes is achievable through affordable blood glucose testing. Individuals with type 1 diabetes require insulin therapy for survival.
An essential aspect of managing diabetes is maintaining a healthy lifestyle.
Some individuals with type 2 diabetes may need medications to help regulate their blood sugar levels. These can include insulin injections, metformin, sulfonylureas, and sodium-glucose co-transporters type 2 inhibitors. In addition to blood sugar-lowering medications, individuals with diabetes may also require drugs to lower blood pressure and statins to reduce complications.
Furthermore, additional medical care may be necessary to address diabetes-related issues, such as foot care for ulcers, screening and treatment for kidney disease, and regular eye exams to detect retinopathy.
WHO response
The World Health Organization (WHO) is dedicated to promoting effective strategies for monitoring, preventing, and managing diabetes and its complications, particularly in low- and middle-income nations. WHO offers evidence-based guidelines for preventing major noncommunicable diseases like diabetes, establishes standards for diabetes diagnosis and treatment, raises awareness about the global diabetes epidemic, and conducts surveillance on diabetes and its risk factors.
In April 2021, WHO introduced the Global Diabetes Compact, a global campaign aimed at enhancing diabetes prevention and care, with a particular emphasis on supporting low- and middle-income countries. The World Health Assembly adopted a Resolution on strengthening diabetes prevention and control in May 2021. By May 2022, the World Health Assembly had endorsed five global diabetes coverage targets to achieve by 2030.
