For millions of people around the world, a confusing diagnosis finally makes sense. Type 5 diabetes has just been officially recognized, and the news matters more than you might think.
“For 25 years, this disease had no official name. Now, an estimated 20 to 25 million people finally do.”
— International Diabetes Federation, April 2025
So, What Is Type 5 Diabetes?
You’ve probably heard of Type 1 and Type 2. They’re very different from each other — and Type 5 is different from both. Here’s a simple way to understand all three:
Your immune system destroys the cells that make insulin. Your body can’t make insulin at all.
Type 2: The Resistance Problem
Your body makes insulin, but it stops listening to it. Often linked to weight and lifestyle factors.
Type 5: The Growth Problem
The pancreas never developed properly due to poor nutrition early in life. It simply can’t make enough insulin.
In Type 5, the root cause goes all the way back to childhood — or even before birth. When a growing child (or developing baby) doesn’t get enough food and nutrients, the pancreas doesn’t have what it needs to grow the right way. Years later, that underdeveloped pancreas struggles to keep up with the body’s need for insulin.
Think of it this way: If a small tree doesn’t get water and sunlight early on, it won’t grow strong — no matter how well you care for it later. Type 5 diabetes works in a similar way. The damage happens long before the diagnosis.
Who Does It Affect?
If you picture a typical person with diabetes, you might imagine someone older or overweight. Type 5 looks completely different. People with this condition are usually:
- Young — often diagnosed before age 30
- Underweight, with a BMI under 18.5 — not overweight
- More often young men than women
- From communities where food has been hard to come by
- Living in low- or middle-income countries, mainly in Asia or Africa
This profile is one of the reasons the condition was so hard to spot. Type 5 patients don’t look like what many doctors expect a diabetes patient to look like — and that’s led to a lot of missed diagnoses over the years.

How Do Doctors Recognize It?
One of the clever ways doctors can spot Type 5 is by looking for something that isn’t there.
The Ketone Clue
In Type 1 diabetes, when the body has zero insulin, it starts breaking down fat in a way that creates chemicals called ketones. These show up in your urine and can be dangerous. Doctors routinely check for them.
In Type 5, the pancreas still makes a little insulin — just not enough. So ketones don’t build up the same way. If a young, underweight patient has high blood sugar but no ketones in their urine, that’s an important clue that Type 5 might be the answer.
This single difference can help doctors avoid misdiagnosing Type 5 as Type 1 — which could lead to completely the wrong treatment plan.
Right now, a new IDF working group — led by Professor Peter Schwarz and Dr. Meredith Hawkins — is developing clear, official guidelines for how doctors everywhere should diagnose Type 5. That work is already underway.
The Surprising History Behind This Diagnosis
Here’s something that might surprise you: Type 5 isn’t a brand-new discovery. It’s been hiding in medical history for decades.
The World Health Organization (WHO) first officially recognized malnutrition-related diabetes as its own condition.
The WHO removed the classification, saying there wasn’t enough evidence to keep it separate. The disease fell into medical limbo.
Patients continue to be misdiagnosed or missed entirely. Research funding is nearly nonexistent for this condition.
New metabolic studies — including key work by Dr. Meredith Hawkins — provide fresh proof that Type 5 is a distinct condition with its own biological pathway.
The IDF officially recognizes Type 5 Diabetes at the World Diabetes Congress in Bangkok. A dedicated working group is launched. The era of medical limbo is over.
Scientists have also uncovered something remarkable about how Type 5 develops. Poor nutrition during pregnancy can change how a baby’s genes are switched on or off — affecting how the pancreas forms before the child is even born. This damage may not show up as diabetes until young adulthood. Researchers call this developmental programming.
Why Does This Recognition Matter So Much?
You might be wondering: why does an official label make such a big difference? In medicine, a name opens doors.
- Better diagnoses — Doctors can now check for Type 5 instead of defaulting to the wrong category
- The right treatments — Type 5 patients have different needs; treatments for Type 2 may be harmful for someone with Type 5
- Research funding — Official recognition means money can be directed toward studying this condition
- Healthcare training — Medical teams in affected countries can learn to recognize and treat it
- Global awareness — International health organizations can now track it, measure it, and fight it
For millions of people who’ve been living with a condition that had no name, this recognition isn’t just medical news. It’s a step toward finally getting the care they deserve.
What Happens Next?
The IDF’s new working group has an important job ahead. They need to create clear rules for how to diagnose Type 5 and share that knowledge with healthcare providers in the countries most affected — places in Asia and Africa where food insecurity is still a serious daily reality for many families.
Treatment will also look different from other types of diabetes. Because Type 5 is rooted in undernutrition — too little food, not too much — focusing on weight loss or cutting carbs would be exactly the wrong approach. Instead, doctors will likely focus on nutritional support and carefully managed insulin therapy.
There’s still a lot of work to do. But for the first time in over two decades, the world is paying attention.
