Which Type of Diabetes Can a 24-Year-Old Get? A Complete Guide

When you are in your twenties, health issues like diabetes might seem like something only older people need to worry about. However, the reality is quite different. If you are wondering which type of diabetes can a 24 year old get, the short answer is that a young adult can develop almost any type of diabetes. Age is no longer a strict barrier when it comes to this chronic condition.

In recent years, doctors across India and the world have seen a significant rise in diabetes cases among young adults. Whether it is due to genetics, autoimmune factors, or lifestyle changes, being 24 does not make you immune. This comprehensive guide will break down everything you need to know about diabetes in your twenties. We will explore the different types, the early warning signs, how it is diagnosed, and what you can do to manage or even prevent it.

The goal here is to keep things simple and educational. By the end of this article, you will have a clear understanding of how diabetes affects young adults and what steps you can take to protect your health.

Can a 24-Year-Old Get Diabetes?

Yes, absolutely. A 24-year-old can get diabetes. In fact, people can develop diabetes at any age, from infancy to old age. The idea that diabetes is strictly an “older person’s disease” is a dangerous myth that needs to be put to rest.

When people ask, “can a 24 year old get diabetes?” or “can diabetes occur at age 25?”, they are often surprised to learn that young adulthood is a common time for certain types of diabetes to appear. Your twenties are a time of major life transitions — starting a career, changing diets, and experiencing new stress levels. These factors, combined with genetics, can trigger the onset of diabetes.

There is no specific age limit for diabetes. While Type 1 diabetes is often diagnosed in childhood, more than half of new cases are now found in adults. Similarly, Type 2 diabetes, which used to be called “adult-onset diabetes” because it mostly affected people over 45, is now increasingly common in young adults and even teenagers due to rising obesity rates and sedentary lifestyles. India, in particular, has seen a worrying surge, with the International Diabetes Federation estimating 89.8 million adults living with diabetes in the country as of 2024.

Understanding the Types of Diabetes in Young Adults

If you are 24 and experiencing symptoms, or if you have just been diagnosed, it is crucial to understand exactly what type of diabetes you are dealing with. The treatment and management for each type are very different. Here is a detailed look at the types of diabetes a 24-year-old can get.

Type 1 Diabetes in Your 20s

Type 1 diabetes is an autoimmune condition. This means your body’s immune system mistakenly attacks and destroys the insulin-producing beta cells in your pancreas. Insulin is a hormone that helps your body use sugar (glucose) for energy. Without insulin, sugar builds up in your blood, leading to serious health problems.

Many people still call this “juvenile diabetes,” believing it only affects children. However, this is incorrect. You can absolutely develop Type 1 diabetes in your twenties. In fact, a 24-year-old or a 25-year-old can get Type 1 diabetes just as easily as a teenager. According to research published in Diabetes Care, more than half of all new Type 1 diabetes cases are now diagnosed in adults. When it strikes in young adulthood, the symptoms can appear suddenly and severely.

People with Type 1 diabetes must take insulin every day to survive. It is not caused by eating too much sugar or having a poor lifestyle; it is primarily driven by genetics and unknown environmental triggers. Type 1 accounts for about 5% to 10% of all diabetes cases, according to the CDC.

Type 2 Diabetes at Age 24

Type 2 diabetes is the most common form of diabetes worldwide, making up roughly 90% to 95% of all cases. In this condition, your body still makes insulin, but it does not use it properly. This is known as insulin resistance. Over time, the pancreas cannot make enough insulin to keep blood sugar levels normal.

You might wonder, “can you have type 2 diabetes at 23 or 24?” The answer is a resounding yes. While it used to be rare in young people, Type 2 diabetes is now surging among those in their twenties. This rise is heavily linked to modern lifestyle factors, including poor diets rich in processed foods, lack of physical activity, and rising obesity rates.

Unlike Type 1, Type 2 diabetes develops gradually. You might have it for years without noticing any clear symptoms. This makes regular health check-ups incredibly important for young adults, especially if you have a family history of the disease. In India, studies have shown that the prevalence of diabetes among young adults has been steadily increasing, with some surveys reporting a prevalence of over 6% in the 20-to-30 age group.

Latent Autoimmune Diabetes in Adults (LADA)

Latent Autoimmune Diabetes in Adults, often referred to as LADA or Type 1.5 diabetes, is a specific type of diabetes that shares characteristics of both Type 1 and Type 2.

LADA is an autoimmune disease like Type 1, meaning the body attacks its own pancreas. However, it progresses much more slowly. Because it usually appears in adulthood (often in people over 30, but it can certainly happen at 24 or 25), and because it progresses slowly, doctors frequently misdiagnose it as Type 2 diabetes. According to the Mayo Clinic, LADA is a type of diabetes that starts in adulthood and slowly gets worse over time.

A young adult with LADA might initially be able to manage their blood sugar with diet, exercise, and oral medications. But eventually, as the pancreas loses its ability to make insulin, they will require insulin therapy, just like someone with Type 1 diabetes. If you are a lean young adult who has been diagnosed with Type 2 but your medications are not working well, it is worth asking your doctor about LADA testing.

Maturity-Onset Diabetes of the Young (MODY)

Maturity-Onset Diabetes of the Young (MODY) is a rare, genetic form of diabetes. It accounts for only about 1% to 5% of all diabetes cases. MODY is caused by a mutation in a single gene, which affects how the pancreas produces insulin. There are multiple subtypes of MODY (at least 14 have been identified), each linked to a different gene.

MODY is typically diagnosed in adolescence or early adulthood, usually before the age of 25. Therefore, a 24-year-old is in the prime age bracket for a MODY diagnosis. Because it is strongly genetic and follows an autosomal dominant inheritance pattern, a young adult with MODY almost always has a parent who also has diabetes. Depending on the specific gene mutation, MODY can sometimes be treated with oral medications rather than insulin, and some forms are so mild they may not need treatment at all.

Gestational Diabetes (For Young Women)

For a 24-year-old woman who is pregnant, gestational diabetes is a significant risk. This type of diabetes develops only during pregnancy, usually around the 24th to 28th week, according to the CDC.

Pregnancy hormones can interfere with how insulin works, leading to insulin resistance. While gestational diabetes usually goes away after the baby is born, it does increase the mother’s risk of developing Type 2 diabetes later in life by up to 50%. It also requires careful management during pregnancy to ensure the health of both the mother and the baby.

Quick Comparison: Types of Diabetes That Can Affect a 24-Year-Old

What Are the First Warning Signs of Diabetes in Young People?

Recognising the early symptoms of diabetes can save your life. The warning signs are generally similar across the different types of diabetes, though they may appear suddenly in Type 1 and very gradually in Type 2.

If you are asking, “what are the first warning signs of type 2 diabetes?” or wondering about Type 1 symptoms, here is what a 24-year-old should look out for:

Excessive Thirst and Frequent Urination. When there is too much sugar in your blood, your kidneys work overtime to filter it out. This excess sugar is excreted in your urine, dragging fluids from your tissues along with it. This makes you urinate much more frequently than normal, which in turn leaves you feeling constantly dehydrated and extremely thirsty.

Unexplained Weight Loss. This is a classic sign of Type 1 diabetes, though it can happen in Type 2 as well. Because your body cannot use the sugar in your blood for energy (due to a lack of insulin), it starts burning fat and muscle for fuel instead. You might be eating more than usual but still losing weight rapidly.

Extreme Fatigue and Weakness. Sugar is your body’s main source of fuel. When that sugar cannot get into your cells to provide energy, you will feel exhausted, weak, and lethargic, no matter how much you sleep.

Blurred Vision. High blood sugar levels can pull fluid from the lenses of your eyes. This affects their ability to focus, leading to blurry vision. If blood sugar levels are brought back to normal, this symptom usually resolves.

Slow-Healing Cuts and Frequent Infections. High blood sugar can impair your blood circulation and weaken your immune system. This means that simple cuts, bruises, or sores take much longer to heal. Young adults might also notice frequent yeast infections or skin infections.

Tingling or Numbness in Hands and Feet. Over time, high blood sugar can damage the nerves in your body, a condition known as diabetic neuropathy. This often starts as a tingling, burning, or numb sensation in the toes, feet, or fingers.

Darkened Skin Patches (Acanthosis Nigricans). Some young adults with insulin resistance develop dark, velvety patches of skin, often on the neck, armpits, or groin. This is a common early indicator of Type 2 diabetes.

If you are 24 and experiencing any of these symptoms, it is vital to see a doctor immediately for a simple blood test.

What Causes Diabetes at Age 24?

The causes of diabetes depend entirely on the type you have. It is important to separate the myths from the facts when understanding why a young adult develops this condition.

Causes of Type 1 Diabetes

The exact cause of Type 1 diabetes remains unknown. However, medical experts know it is an autoimmune reaction. Your body’s defence system attacks the insulin-producing beta cells in the pancreas.

Genetics play a significant role. If you have a family member with Type 1 diabetes, your risk is higher. According to WebMD, if one parent has Type 1 diabetes, the child’s risk is 1% to 8%, and if both parents have it, the risk climbs to about 30%. Researchers also believe that certain environmental factors, such as a viral infection, might trigger the autoimmune response in people who are genetically predisposed. It is crucial to note that Type 1 diabetes is not caused by eating too much sugar or living an unhealthy lifestyle.

Risk Factors for Type 2 Diabetes in Young Adults

Unlike Type 1, Type 2 diabetes is strongly linked to lifestyle factors, though genetics still play a part. The primary cause is insulin resistance, where the body’s cells stop responding properly to insulin.

For a 24-year-old, the major risk factors for developing Type 2 diabetes include being overweight or obese (especially with excess belly fat), leading a sedentary lifestyle with little physical activity, consuming a diet high in processed foods, sugary drinks, and refined carbohydrates, having a parent or sibling with Type 2 diabetes, and for young women, having Polycystic Ovary Syndrome (PCOS). South Asian populations, including Indians, are also known to have a higher genetic predisposition to insulin resistance and Type 2 diabetes, even at lower body weight levels compared to Western populations.

How is Diabetes Diagnosed in Young Adults?

If a doctor suspects you have diabetes, they will order specific blood tests to confirm the diagnosis. These tests measure the amount of glucose in your blood.

The HbA1c Test. This is the most common test for diagnosing diabetes. It measures your average blood sugar levels over the past two to three months. An HbA1c level of 6.5% or higher on two separate tests indicates diabetes. A level between 5.7% and 6.4% indicates prediabetes.

Fasting Blood Sugar Test. For this test, you must fast (not eat or drink anything except water) for at least eight hours, usually overnight. A fasting blood sugar level of 126 mg/dL or higher indicates diabetes. A level between 100 and 125 mg/dL indicates prediabetes.

Random Blood Sugar Test. This test can be taken at any time of the day, regardless of when you last ate. A blood sugar level of 200 mg/dL or higher, especially when accompanied by symptoms like extreme thirst and frequent urination, strongly suggests diabetes.

Oral Glucose Tolerance Test (OGTT). This test involves drinking a sugary solution and then having your blood sugar measured after two hours. A reading of 200 mg/dL or higher indicates diabetes.

Autoantibody Tests. If a 24-year-old is diagnosed with diabetes, the doctor needs to determine if it is Type 1, Type 2, or LADA. To do this, they will test for specific autoantibodies (such as GAD antibodies) that are present in Type 1 and LADA but absent in Type 2. They may also test C-peptide levels to see how much insulin the pancreas is still producing.

Can a 20-Year-Old Get Diabetes?

Yes, a 20-year-old can absolutely get diabetes. There is no magical age threshold below which you are safe. Type 1 diabetes can develop at any age, and it is not uncommon for it to first appear in the late teens or early twenties. Type 2 diabetes, while traditionally associated with older adults, is now being diagnosed in people as young as their late teens and early twenties, particularly in countries like India where lifestyle changes have been rapid.

If you are 20 and have risk factors such as a family history of diabetes, excess weight, or a sedentary lifestyle, it is wise to get your blood sugar levels checked regularly. Early detection can make a world of difference in managing the condition effectively.

Can Diabetes Be Cured?

When a 24-year-old is diagnosed with diabetes, the first question is often, “Can it be cured?” The answer depends entirely on the type of diabetes.

Can Type 1 Diabetes Be Cured?

Currently, there is no cure for Type 1 diabetes. Because it is an autoimmune disease that destroys the insulin-producing cells, the body cannot repair or replace them on its own. A young adult with Type 1 diabetes will need to take insulin for the rest of their life to manage their blood sugar levels. However, with proper management, people with Type 1 diabetes can live long, healthy, and active lives. Ongoing research into beta cell transplants and immunotherapy offers hope for the future, but a definitive cure is not yet available.

Can Type 2 Diabetes Be Cured?

While there is no permanent “cure” for Type 2 diabetes, it can often be put into remission, especially if caught early in a young adult. Remission means that your blood sugar levels return to a normal, healthy range without the need for diabetes medication.

For a 24-year-old, achieving remission usually requires significant lifestyle changes. This includes losing a substantial amount of weight (if overweight), adopting a healthy, balanced diet rich in whole grains, vegetables, and lean proteins, and engaging in regular physical activity of at least 150 minutes per week. However, even in remission, the underlying tendency for insulin resistance remains, so these healthy habits must be maintained for life to prevent the diabetes from returning.

How is Diabetes Treated in Your 20s?

Managing diabetes in your twenties requires a proactive approach. The treatment plan will be tailored to the specific type of diabetes you have.

Treating Type 1 Diabetes

The cornerstone of Type 1 diabetes treatment is insulin therapy. Because the pancreas no longer produces insulin, it must be introduced into the body artificially. This is done through multiple daily injections or an insulin pump.

A 24-year-old with Type 1 diabetes will also need to monitor their blood sugar levels frequently, often using a continuous glucose monitor (CGM). They must learn how to count carbohydrates in their food to calculate the correct insulin dose and understand how exercise and stress affect their blood sugar. Regular visits to an endocrinologist and a diabetes educator are essential for staying on track.

How is Type 2 Diabetes Treated?

The initial treatment for Type 2 diabetes in a young adult focuses heavily on lifestyle modifications. A doctor will recommend a diet rich in whole foods, vegetables, and lean proteins, while cutting out sugary drinks and processed snacks. Regular exercise, such as brisk walking, cycling, or swimming, is crucial for improving insulin sensitivity.

If lifestyle changes are not enough to control blood sugar levels, medications will be prescribed. The most common first-line medication is Metformin, which helps the body use insulin more effectively and reduces the amount of sugar produced by the liver. In some cases, if the diabetes is advanced or poorly controlled, a young adult with Type 2 diabetes may also need insulin therapy or other injectable medications.

How to Prevent Diabetes at a Young Age

While Type 1 diabetes and MODY cannot be prevented because they are driven by genetics and autoimmune factors, Type 2 diabetes is largely preventable, even if you have a family history. For a 24-year-old, prevention comes down to making smart lifestyle choices.

Maintaining a healthy weight is the single most effective way to reduce your risk. Even losing just 5% to 7% of your body weight can dramatically lower your chances of developing Type 2 diabetes. Staying physically active for at least 30 minutes a day, eating a balanced diet that limits processed foods and sugary beverages, managing stress through mindfulness or relaxation techniques, getting enough quality sleep (7 to 9 hours per night), and avoiding smoking and excessive alcohol consumption are all proven strategies.

If you have a family history of diabetes, getting annual blood sugar screenings from your early twenties is a wise decision. Catching prediabetes early gives you the best chance of reversing it before it progresses to full-blown diabetes.

Myths vs. Facts About Diabetes in Young Adults

There is a lot of misinformation surrounding diabetes, especially when it affects young people. Let us clear up some common misconceptions.

Myth: Only old people get Type 2 diabetes.

Fact: While it was once called “adult-onset diabetes,” Type 2 diabetes is now increasingly common in young adults, teenagers, and even children, largely due to rising obesity rates and sedentary lifestyles.

Myth: Eating too much sugar causes Type 1 diabetes.

Fact: Type 1 diabetes is an autoimmune condition driven by genetics and unknown environmental triggers. It has nothing to do with your diet or lifestyle choices.

Myth: You can’t live a normal life with diabetes in your 20s.

Fact: With proper management, education, and support, young adults with any type of diabetes can pursue their careers, travel, play sports, and live full, active lives. Many athletes, celebrities, and professionals manage diabetes successfully.

Myth: Thin people cannot get diabetes.

Fact: While being overweight is a major risk factor for Type 2 diabetes, thin individuals can develop Type 1, LADA, or MODY. In India, many lean individuals develop Type 2 diabetes due to genetic predisposition and visceral fat.

Myth: Diabetes always requires insulin injections.

Fact: Only Type 1 diabetes always requires insulin. Many people with Type 2 diabetes manage their condition with lifestyle changes and oral medications alone. Some forms of MODY do not even require medication.

Key Takeaways

Understanding which type of diabetes can a 24 year old get is the first step towards taking control of your health. Here is a quick summary of the most important points from this guide:

A 24-year-old can develop almost any type of diabetes, including Type 1, Type 2, LADA, MODY, and gestational diabetes. Type 1 diabetes is autoimmune and requires lifelong insulin therapy; it is not caused by lifestyle factors. Type 2 diabetes is rising rapidly in young adults, driven by obesity and inactivity, but it can often be managed or put into remission with lifestyle changes. LADA is frequently misdiagnosed as Type 2, so proper testing is essential. MODY is a rare genetic form typically diagnosed before age 25. Early detection through regular blood sugar testing is vital, especially if you have a family history. Prevention of Type 2 diabetes is possible through maintaining a healthy weight, staying active, and eating well.

If you suspect you might have diabetes, do not delay. Visit your doctor, get tested, and take the first step towards a healthier future.

Frequently Asked Questions (FAQs) on Which Type of Diabetes Can a 24-Year-Old Get?

What is the age limit for diabetes?

There is no age limit for diabetes. It can develop at any stage of life, from infancy to old age. While certain types are more common in specific age groups (for example, Type 1 is often diagnosed in children and young adults, while Type 2 is more common in those over 45), age alone does not prevent anyone from getting diabetes.

Can a 25-year-old get Type 1 diabetes?

Yes, a 25-year-old can absolutely get Type 1 diabetes. While it is often diagnosed in childhood, more than half of all new Type 1 diabetes cases are now diagnosed in adults. It can develop at any age, and young adults in their twenties are not exempt.

Can diabetes occur at age 20?

Yes, diabetes can occur at age 20. Young adults in their twenties can develop Type 1, Type 2, or other forms like LADA and MODY, depending on their genetics, lifestyle factors, and overall health. Regular screening is recommended if you have risk factors.

What are the first warning signs of type 2 diabetes?

The first warning signs of Type 2 diabetes include excessive thirst, frequent urination (especially at night), extreme fatigue, blurred vision, slow-healing cuts or bruises, and darkened patches of skin on the neck or armpits. Because these symptoms develop gradually, many people do not notice them until the condition has progressed.

Can you have type 2 diabetes at 23?

Yes, you can have Type 2 diabetes at 23. The incidence of Type 2 diabetes in young adults is rising sharply due to increasing rates of obesity, poor diets, and sedentary lifestyles. If you are 23 and have risk factors, getting your blood sugar tested is highly recommended.

What is the normal Type 2 diabetes range?

A normal fasting blood sugar level is below 100 mg/dL. A level between 100 and 125 mg/dL indicates prediabetes. A fasting blood sugar level of 126 mg/dL or higher on two separate tests confirms a diabetes diagnosis. An HbA1c level below 5.7% is considered normal, while 6.5% or higher indicates diabetes.

Which diabetes test is best for a 24-year-old?

The best initial tests are the HbA1c test and the Fasting Blood Sugar test. If diabetes is confirmed, a doctor may also order autoantibody tests (such as GAD antibodies) and C-peptide tests to determine whether it is Type 1, Type 2, or LADA. For suspected MODY, genetic testing may be recommended.

Is diabetes in young adults more dangerous than in older adults?

Research suggests that Type 2 diabetes diagnosed in young adults can be more aggressive than when diagnosed later in life. Young adults with Type 2 diabetes tend to develop complications faster and may have a harder time achieving blood sugar control. This makes early diagnosis and proactive management even more critical for people in their twenties.
