Why Have Diabetes Rates Doubled in the Last 30 Years? Global Study Reveals Alarming Trends
Diabetes rates have more than doubled globally in the past three decades, with over 800 million people now living with the disease.Yet, over half of these individuals remain untreated, especially in low- and middle-income countries.

A new study published in The Lancet paints a stark picture of the growing diabetes epidemic, with rising obesity rates, an aging population, and poor access to healthcare driving the surge. The article explored the key factors contributing to the diabetes crisis, the challenges in treatment access, and potential solutions to curb the spread of the disease.

Diabetes: A Growing Global Health Crisis

Diabetes is a chronic condition that occurs when the body cannot effectively regulate blood glucose levels. This is either due to the pancreas failing to produce enough insulin or the body becoming resistant to the insulin it produces. If left uncontrolled, high blood sugar levels can lead to severe complications, including heart disease, kidney damage, and nerve issues.

There are two main types of diabetes:

  • Type 1 Diabetes: An autoimmune condition where the body attacks insulin-producing cells in the pancreas. It is less common but requires lifelong insulin therapy.
  • Type 2 Diabetes: The more prevalent form, affecting over 95% of those diagnosed. It develops when the body becomes resistant to insulin or doesn’t use it effectively. Type 2 diabetes can often be prevented or managed through lifestyle changes.

The Alarming Growth in Diabetes Cases

According to the Lancet study, the global prevalence of diabetes in adults has skyrocketed over the past 30 years, from around 7% in 1990 to nearly 14% in 2022. This translates to an estimated 828 million adults living with diabetes today, an increase of more than 630 million people.

Key statistics from the study include:

  • India accounts for more than a quarter of global diabetes cases, with a prevalence rate exceeding 20%.
  • The United States and the United Kingdom have the highest diabetes rates among high-income nations, with figures of 12.5% and 8.8%, respectively.

This dramatic increase in diabetes rates is closely tied to rising levels of obesity, which is a major risk factor for developing Type 2 diabetes. Nearly 1 billion adults worldwide are living with obesity, and as the global population ages, the number of individuals at risk for diabetes continues to climb.

Why Are Diabetes Rates So High?

Several factors are contributing to the global rise in diabetes rates:

  • Obesity: As the World Obesity Federation reports, nearly 1 billion adults and 159 million children suffer from obesity, a major precursor to Type 2 diabetes.
  • Aging Population: The world’s growing elderly population is more prone to diabetes, as the disease tends to develop with age.
  • Access to Healthy Food: In many countries, unhealthy food is cheap, widely available, and heavily marketed, while healthy options are becoming increasingly expensive and harder to access due to climate change disruptions like droughts and floods.
  • Lack of Safe Spaces for Exercise: In some regions, particularly in low-income countries, safe spaces for physical activity are limited, further exacerbating the problem.

The State of Diabetes Treatment

While diabetes treatment is accessible in many high-income countries, it remains a significant challenge in low- and middle-income countries (LMICs), where access to healthcare and medication is limited. The Lancet study found that nearly 450 million people with diabetes remain untreated globally, up from 128 million in 1990.

This gap is most pronounced in LMICs, where undiagnosed cases are common, and treatment access is often hindered by:

  • Economic barriers: High costs of diabetes drugs and healthcare services.
  • Lack of awareness: Many individuals are unaware of their condition until complications arise.
  • Healthcare infrastructure: Inadequate healthcare systems that struggle to meet the needs of growing populations.

What Needs to Be Done?

Experts agree that a multifaceted approach is needed to combat the diabetes epidemic:

  • Improved access to healthcare: Increasing access to doctors and healthcare services, especially in underserved areas, is crucial for early diagnosis and prevention.
  • Affordable medication: Reducing the cost of diabetes drugs, especially in LMICs, would make treatment more accessible to those in need.
  • Prevention through lifestyle changes: Encouraging healthy diets, physical activity, and weight management can significantly reduce the risk of developing diabetes. In particular, reducing sugar consumption in early childhood has been shown to protect against diabetes and high blood pressure later in life.

Johanna Ralston, CEO of the World Obesity Forum, stressed the importance of preventive measures: “Countries must adopt a systematic approach focusing on prevention, public health policies, and limiting exposure to unhealthy food marketing, especially to children.”

As diabetes continues to reach pandemic proportions, global action is needed to halt its progression. Efforts to improve prevention, expand access to treatment, and address the root causes of the disease are critical.
