More than 8 in 10 people with prediabetes don’t know it. Do you have these signs?
Did you know that a staggering 80% of individuals with prediabetes are unaware of their condition? These signs can seem mild, so many people miss them. Dr. Monaa Zafar, MD, says early detection offers the best chance to reverse prediabetes.
People may blame fatigue or thirst on stress, aging, or poor sleep. Yet these symptoms may signal a serious health problem. According to the CDC’s National Diabetes Statistics Report, more than 115 million American adults have prediabetes.
More than 8 in 10 people with prediabetes don’t know it. Prediabetes may cause no clear symptoms. Pay attention to your body, even if you feel fine, because you may still face risk.
Do you have these signs? Next, we will explore signs your body may send you. Understanding them can help you take steps toward better health.
Early detection can support treatment and may even reverse prediabetes.
What prediabetes is and why the silent epidemic matters
Understanding prediabetes is crucial as it represents a significant health risk. Prediabetes occurs when your blood sugar is higher than normal but not high enough for type 2 diabetes.
Many are living with prediabetes, according to the CDC’s 2026 National Diabetes Statistics Report. This condition often develops silently, so experts call it a silent epidemic.
When you have prediabetes, your body may develop insulin resistance. Your cells do not respond well to insulin, the hormone that moves glucose from your blood into cells for energy.
Your pancreas then makes more insulin to compensate. Over time, it may struggle to keep up, causing high blood sugar.
Even mildly elevated blood sugar can damage small blood vessels and nerves. This damage raises the risk of serious problems, including heart disease and kidney problems.
Know the diagnostic ranges to understand your risk. Prediabetes includes an A1C level of 5.7% to 6.4%.
It also includes fasting blood glucose of 100 to 125 mg/dL or an OGTT of 140 to 199 mg/dL. These levels indicate prediabetes.
Knowing what prediabetes is makes the warning signs in the next section more meaningful. With this knowledge, you can take proactive steps to manage your health and reduce your risk of type 2 diabetes.
Eight quiet warning signs your body may be sending
Your body can send important health messages. Noticing them may help you take early steps toward better well-being. Here are eight subtle warning signs that may indicate prediabetes.
1. Dark, velvety patches on the skin
You may see dark, velvety patches on the skin around your neck, armpits, groin, or knuckles. This condition, called acanthosis nigricans, often links to insulin resistance. Soft, thick skin may seem harmless, but it can signal blood sugar problems and need further evaluation.
2. Skin tags
Skin tags are small, harmless growths that often form where skin rubs together on many body areas. They are often linked to insulin resistance, like dark patches. An increase in skin tags may remind you to monitor your blood sugar and pay attention to your health.
3. Increased thirst
Increased thirst may signal polydipsia, a condition that makes your body crave more fluids. When blood sugar rises, your kidneys filter extra glucose and pull water from tissues. This can cause dehydration and constant thirst, so notice if you reach for water more often.
4. Frequent urination
Frequent urination, called polyuria, often occurs with increased thirst and high blood sugar. Your kidneys remove excess glucose, leading to more bathroom trips, especially at night. Do not dismiss this pattern as aging or fluid intake; it may show blood sugar trouble.
5. Ongoing fatigue
Do you feel tired even after a full night’s sleep? Ongoing fatigue may occur when your body cannot process blood sugar well. Your cells may lack energy despite high blood sugar, so unusual exhaustion deserves a health check.
6. Blurred vision
Fluctuating blood sugar can cause blurred vision that changes from clear to blurry. High glucose may swell the eye lens, changing its shape and making focus harder. Vision changes deserve attention because they may signal an early health problem.
7. Cuts and sores that heal slowly
Cuts and sores that heal slowly may signal a problem. High blood sugar can slow healing by affecting blood flow and immune function. Do not dismiss slow-healing wounds as signs of aging; they may indicate trouble managing glucose.
8. Numbness or tingling in the hands or feet
Numbness or tingling in the hands or feet may signal peripheral neuropathy. You may feel mild tingling or burning in your toes or fingertips. These sensations can signal nerve damage and more serious complications, so do not overlook them or assume another cause.
Recognizing these eight quiet warning signs can support your health. If you notice any, discuss them with your healthcare provider. Taking action early can make a meaningful difference in managing your health.
Why these signs don’t confirm prediabetes on their own
These signs do not confirm prediabetes on their own. Thirst and fatigue can result from stress, poor sleep, thyroid problems, or vitamin deficiencies.
Many people with prediabetes have no noticeable symptoms, making the condition hard to detect. About 8 out of 10 people with prediabetes do not know they have it. Only a blood test can confirm prediabetes.
Treat these signs as reasons to ask for a blood test, not proof of prediabetes. If you notice symptoms, contact your healthcare provider. They can review your risk factors and recommend appropriate testing.
Recognizing these signs matters, but they should not cause alarm. Understanding the full picture helps you manage your health.
When to get screened for prediabetes
Understanding when to get screened for prediabetes is crucial for your health. The American Diabetes Association’s 2026 Standards of Care recommend routine screening for prediabetes and type 2 diabetes. This screening should begin for all adults at age 35.
If the first screen is normal, the guidelines recommend repeat testing at least every 3 years. This approach catches prediabetes early, especially because it often shows no symptoms.
The ADA says early detection is key. Regular screenings identify people who may not know they have prediabetes. Providers can track changes over time by starting at age 35.
If initial results are normal, repeat screening every three years to track your blood sugar.
Risk factors that call for earlier screening
If you have certain risk factors, begin screening before age 35 and repeat it more often. These risk factors include:
- BMI over 25 (or 23 for Asian Americans)
- Family history of type 2 diabetes
- History of gestational diabetes or polycystic ovary syndrome (PCOS)
- High blood pressure (130/80 mmHg or higher)
- Abnormal cholesterol or triglyceride levels
- History of cardiovascular disease
- Sedentary lifestyle
- Belonging to higher-risk racial or ethnic groups, including African American, Hispanic, Native American, Asian American, or Pacific Islander
Dr. Zafar notes, “Both the American Diabetes Association and U.S. Preventive Services Task Force recommend screening adults over age 35 every three years. If you have these risk factors, start earlier and screen more often.”
If any risk factor applies to you, ask your healthcare provider about getting screened sooner.
Knowing when to get screened helps prevent prediabetes from progressing to type 2 diabetes.
The blood tests doctors use to diagnose prediabetes
Understanding how doctors diagnose prediabetes can help protect your health. Doctors can use a fasting glucose test, an oral glucose tolerance test or an A1C. These tests show your blood sugar levels and help guide your next steps.
Fasting glucose test
This simple test measures blood sugar after an overnight fast of at least eight hours. A result from 100 to 125 mg/dL may indicate prediabetes. It is often the first step doctors take.
What is a fasting glucose test? It shows how well your body manages sugar without recent food. The test is quick and gives a clear snapshot of your glucose levels.
Oral glucose tolerance test
The oral glucose tolerance test (OGTT) also helps diagnose prediabetes. You drink a glucose solution, and doctors measure your blood sugar two hours later. A result from 140 to 199 mg/dL suggests prediabetes and shows how your body processes sugar over time.
A1C test
The A1C test measures average blood sugar over the past two to three months. It measures the percentage of hemoglobin in red blood cells coated with sugar. An A1C result from 5.7% to 6.4% indicates prediabetes and helps track long-term blood sugar control.
Any of these three tests can diagnose prediabetes, so seek care sooner if symptoms appear or weight climbs. After your diagnosis, your doctor may recommend annual retesting to monitor your condition. Early detection matters. “The sooner you know, the sooner you can take action.”
How prediabetes can be reversed
Many people feel overwhelmed after a prediabetes diagnosis. However, it’s essential to remember that prediabetes can be reversed. The diagnosis is not a life sentence. It is a wake-up call for positive change.
The Diabetes Prevention Program findings
In the landmark diabetes prevention program trial, adults at high risk lost 5 to 7 percent of their body weight. They got at least 150 minutes of moderate activity a week. Their risk of developing type 2 diabetes fell by 58 percent.
This evidence shows that modest lifestyle changes can bring major health improvements.
Dr. Zafar emphasizes, “Losing just 5 to 10 percent of your starting body weight can significantly improve insulin resistance.” Even small steps can make a big difference in your health journey.
Putting the plan into practice
To use these findings, aim for 150 minutes of moderate activity each week. Walking, dancing, or swimming can help you reach this goal. Get 6 to 9 hours of quality sleep each night, since sleep supports overall health.
Also, try stress relief practices such as journaling, yoga, or deep breathing. These practices can improve your well-being and help manage prediabetes.
Choose a more plant-forward diet with fiber-rich foods and lean proteins. Consider joining a CDC-approved Diabetes Prevention Program, which may be covered by insurance. Tools like MyFitnessPal or Lose It can help track progress and maintain motivation.
Remember, reversing prediabetes means celebrating progress, not perfection. Small, lasting changes can lead to major health improvements.
What you can do at your next doctor’s visit
Your next doctor’s visit is a good time to discuss prediabetes and related symptoms. Before then, review your symptoms and record when they began. Anyone noticing these signs can ask a primary care clinician for an A1C or fasting glucose test. This includes anyone never screened past age 35.
- List your symptoms: Write down any symptoms you’ve noticed and when they first appeared. This will help your doctor better understand your situation.
- Family history: Be prepared to discuss your family history of type 2 diabetes. This information is crucial for assessing your risk.
- Identify risk factors: Know which risk factors apply to you, such as obesity or a sedentary lifestyle, and share these with your healthcare provider.
- Request testing: Anyone who notices these signs or has never been screened after age 35 can ask a primary care clinician for an A1C or fasting glucose test at their next visit.
Describe your symptoms clearly and fully. These details help healthcare providers rule out other conditions. If you feel embarrassed or unsure, remember that these talks are a normal part of preventive care.
“A quick conversation with your doctor is the best place to start.”
These steps can help you take charge of your health. Ask questions and seek clear answers about your concerns. Your health is worth discussing.
