Pre diabetes is one of the most overlooked health conditions today. Many people walk around with rising blood sugar levels without realising that their body is quietly sending signals. When sugar levels begin to climb but haven’t reached the point of type 2 diabetes, doctors call it pre diabetes. It means the body is struggling to use insulin properly. The good news is that you can manage it, and in many cases, reverse it by making steady changes.
The number of people with pre diabetes is increasing every year. Fast food, sitting for long hours, stress, and poor sleep habits all contribute. Many people blame age or genetics, but lifestyle takes a bigger share of responsibility. This is why doctors say pre diabetes is a wake-up call rather than a life sentence.
If you learn how to spot the early symptoms, Pre Diabetes Symptoms and Treatment, improve your daily choices, and monitor your numbers, you can protect yourself from type 2 diabetes. This guide explains everything in simple, clear language. You’ll learn about early signs, causes, prevention, diagnosis, and treatments that work in real life. The aim is to help you understand your body better and make changes that truly matter.
What Is Pre Diabetes?
Pre diabetes is a stage where your blood sugar is higher than normal but not high enough to be diagnosed as diabetes. The body produces insulin, but it doesn’t use it as well as it should. This is called insulin resistance. When this happens, sugar stays in the blood instead of entering the cells for energy.
Many people think pre diabetes means they will definitely develop diabetes. That is not true. With the right steps, the progress can slow down or even reverse. Think of it as an early alert system. Your body is telling you that something needs attention.
Here’s how pre diabetes differs from diabetes:
- In pre diabetes, fasting blood sugar is usually between 100 to 125 mg/dL.
- In diabetes, fasting sugar is 126 mg/dL or more.
- In pre diabetes, the A1c test is between 5.7% and 6.4%.
- In diabetes, the A1c is 6.5% or more.
Pre diabetes often does not cause noticeable symptoms in the early stages, which is why many people don’t realise they have it. That’s why testing and awareness are important.
Causes of Pre Diabetes
Pre diabetes develops gradually. It doesn’t appear overnight, and it doesn’t happen because of one single mistake. It builds up over months or years due to a mix of genetics, lifestyle choices, and biological changes in the body. Understanding these causes can help you take control early and lower your risk.
1. Genetics
Family history plays a real role in pre diabetes. If your parents or siblings have type 2 diabetes, your chances are naturally higher. This doesn’t mean you will definitely develop pre diabetes. It simply means you need to be more aware of your habits. Genetics can open the door, but lifestyle decides whether the condition progresses or stays under control. Even people with a strong family history can prevent pre diabetes with healthy choices.
2. Insulin Resistance
Insulin resistance is one of the biggest reasons behind pre diabetes. Insulin is the hormone that helps sugar move from the blood into the cells. When the cells stop responding to insulin properly, the pancreas tries to compensate by producing more. This keeps sugar levels normal for a while, but eventually the system gets tired. When insulin isn’t effective, sugar remains in the blood and starts rising slowly. This stage is where pre diabetes begins.
3. Poor Diet
Your diet has a direct impact on your blood sugar levels. Eating too many sugary drinks, packed foods, white bread, pastries, fried snacks, and processed meals forces your body to release more insulin. Refined carbs break down quickly and spike sugar levels. Over time, this leads to insulin resistance. A diet lacking in fibre, protein, and healthy fats also makes it hard for the body to manage glucose. Many people underestimate how much small daily choices affect long-term sugar control.
4. Being Overweight
Weight gain, especially around the belly area, is strongly linked with pre diabetes. Excess abdominal fat interferes with how insulin works. It makes the cells less sensitive and increases inflammation inside the body. Even if someone looks slim but carries more fat around the waist, the risk still rises. Losing a small amount of weight, even 5 to 7 percent of body weight, can significantly improve insulin sensitivity.
5. Inactivity
The body is designed to move. When you sit for hours at a desk, in front of a TV, or in a car, your muscles use less glucose. This makes insulin less effective. Regular movement helps the muscles absorb sugar naturally. Simple habits like walking after meals, stretching every hour, or adding light workouts make a big difference in preventing pre diabetes.
6. Stress
Stress creates hormonal changes that push sugar levels higher. When you feel stressed, your body releases cortisol and adrenaline. These hormones increase blood sugar because the body thinks it needs extra energy. If stress is constant, sugar stays elevated and the insulin system becomes weaker. Stress management is an important but often ignored part of blood sugar control.
7. Poor Sleep
Sleep affects hunger hormones, metabolism, and insulin response. Sleeping too little, sleeping late, or constantly changing sleep patterns disrupts the body’s rhythm. This makes you crave sugary foods, feel tired, and gain weight easily. All of these increase the chance of developing pre diabetes.
8. Hormonal Conditions
Certain conditions like PCOS, thyroid disorders, and hormonal imbalance affect how the body uses insulin. Women with PCOS have a higher risk because their hormones influence metabolism. Thyroid issues can also slow down the body’s functions, leading to weight gain and sugar imbalance. Treating these underlying conditions can lower your risk of pre diabetes.
Risk Factors You Should Know

Some people are naturally at higher risk. Knowing these factors helps you stay aware:
- Age above 40
- Family history of diabetes
- Overweight or obese
- High blood pressure
- High cholesterol
- PCOS
- Having a history of gestational diabetes
- Smoking
- Sedentary lifestyle
- Large waist size
These do not guarantee pre diabetes, but they increase your chances. The earlier you identify them, the better.
Early Symptoms of Pre Diabetes
Pre diabetes usually develops quietly. Many people feel completely normal in the early stages, which is why the condition often goes unnoticed. Still, the body does send signals, and recognising them early can make a big difference. These symptoms may appear mild, but together they form a pattern that should not be ignored. Here are the most common early signs of pre diabetes explained in simple and natural language.
1. Fatigue
Feeling tired is one of the earliest symptoms. When sugar stays in the blood instead of entering the cells, the body lacks the energy it needs. Even after a full night’s sleep, you may wake up feeling drained or struggle to stay active during the day. This constant tiredness is a sign that your cells are not receiving enough fuel.
2. Increased Thirst
High sugar levels pull water from your tissues, which leaves your mouth dry. You may feel thirsty more often and drink large amounts of water. Some people even wake up at night to drink. If you find yourself carrying a bottle everywhere or constantly feeling thirsty, it’s worth paying attention.
3. Frequent Urination
When you drink more water, you naturally urinate more. The body tries to flush out the excess sugar through urine. This leads to frequent trips to the toilet, especially at night. Waking up multiple times to urinate can interfere with sleep and make you feel tired the next day.
4. Unusual Hunger
Unusual hunger or feeling hungry soon after eating is another early sign. Even if you’ve had a good meal, the cells may not be getting the glucose they need. This makes the body signal hunger again. Many people mistake this for emotional eating or stress eating, but it can be linked to rising sugar levels.
5. Blurred Vision
Pre diabetes can temporarily affect the fluid in your eyes. As sugar levels fluctuate, the shape of the eye lens can change, causing blurry vision. This change is usually temporary and may come and go. Many people ignore this symptom because it clears up on its own, but it’s an important warning sign.
6. Slow Healing
If your cuts, scratches, or bruises take longer than usual to heal, it may be due to high sugar levels. Sugar affects blood circulation and slows down the healing process. Even small wounds can take extra time to close properly. Repeated slow healing episodes are worth noting.
7. Dark Skin Patches
Dark, velvety patches of skin, especially around the neck, armpits, or groin, are called acanthosis nigricans. This is one of the clearest skin signs of insulin resistance. Many people first notice this around the neck and assume it’s dirt or pigmentation. In reality, it’s often linked to pre diabetes.
8. Tingling or Numbness
Early nerve irritation is another sign. Tingling, numbness, or a “pins and needles” feeling in the hands or feet may appear when sugar levels fluctuate. This usually starts mildly and may come and go.
9. Sudden Weight Changes
Some people gain weight due to hormonal changes and insulin resistance. Others lose weight because their body cannot properly use glucose for energy. Both weight gain and weight loss can happen in pre diabetes, depending on how the body reacts.
10. Skin Infections
High sugar creates an environment where bacteria and fungi grow easily. Frequent skin infections, rashes, boils, or itching can indicate rising sugar levels. People with pre diabetes often notice repeated infections that take time to heal.
Silent Symptoms People Often Ignore
Some signs are mild and easy to miss:
- Mood swings
- Brain fog
- Sleep problems
- Sugar cravings
- Afternoon slump
- Irritability after meals
- Mild digestive discomfort
These symptoms may not seem serious individually, but together, they point towards rising sugar levels.
How Pre Diabetes Is Diagnosed
Doctors use a few simple tests:
1. Fasting Blood Sugar (FBS)
You need to fast for 8 hours.
- Normal: below 100 mg/dL
- Pre diabetes: 100–125 mg/dL
- Diabetes: 126 mg/dL or more
2. HbA1c Test
Shows average sugar level for the past 2–3 months.
- Pre diabetes: 5.7%–6.4%
- Diabetes: 6.5% or more
3. Oral Glucose Tolerance Test (OGTT)
A 2-hour test after drinking a sugar solution.
- Pre diabetes: 140–199 mg/dL
4. Random Blood Sugar
Useful when fasting is not possible.
5. Home Monitoring
Digital glucometers help track sugar levels regularly.
If you have risk factors or symptoms, testing once a year is a wise choice.
Health Risks Linked to Untreated Pre Diabetes
Ignoring pre diabetes can lead to serious health problems. Here are the main risks:
- Type 2 diabetes
- Heart disease
- Stroke
- Kidney problems
- Nerve damage
- Eye diseases
- Fatty liver
- Sleep apnea
- Increased infection risk
- Hormonal imbalance
These complications develop slowly. That’s why early treatment matters.
Treatment Options for Pre Diabetes
The best part about pre diabetes is that treatment is straightforward. The goal is to lower blood sugar, improve insulin sensitivity, and protect organs.
Lifestyle Treatment
1. Losing Weight Slowly
Even a 5%–7% weight loss can make a huge difference. It reduces insulin resistance and helps bring sugar levels down.
2. Better Diet
A diet with fibre, whole grains, vegetables, lean proteins, and healthy fats supports blood sugar balance.
3. Regular Exercise
Movement improves insulin sensitivity. Walking alone can lower sugar levels significantly.
4. Reducing Stress
Practising calm breathing, meditation, or hobbies helps reduce stress hormones.
5. Sleeping Better
Aim for 7–8 hours of steady sleep. Poor sleep disrupts sugar levels.
6. Cutting Sugar & Refined Foods
Avoid sugary drinks, snacks, and packed foods. Replace them with whole options.
7. Staying Active All Day
Stand up and move every hour if you sit for long.
Medical Treatment
1. Metformin
Doctors prescribe Metformin when lifestyle changes are not enough. It lowers sugar and improves insulin sensitivity.
2. Medications for Cholesterol or BP
If needed, doctors might address related conditions.
3. Regular Monitoring
Checking sugar levels helps you stay on track.
4. Follow-up Visits
Adjustments are often required based on your progress.
Best Diet for Pre Diabetes
Food plays a big role in reversing pre diabetes. Here’s what a healthy diet looks like.
1. High-Fibre Foods
- Oats
- Vegetables
- Beans
- Fruits with skin
- Whole grains
Fibre slows sugar absorption.
2. Low-Glycaemic Index Foods
Such foods don’t cause sudden sugar spikes.
Examples: quinoa, brown rice, sweet potatoes, lentils.
3. Lean Proteins
Eggs, fish, chicken, tofu, chickpeas, paneer.
4. Healthy Fats
Olive oil, avocados, nuts, seeds.
5. Hydration
Drink water regularly. Avoid sweet drinks.
6. Meal Timing
Eat at the same time every day. Avoid late-night heavy meals.
7. Sample 7-Day Diet Plan
A simple plan may include:
- Warm lemon water
- Oatmeal or poha
- Roti with vegetables
- Dal, salad, and curd
- Nuts and seeds
- Early dinner with soup and protein
Foods to Avoid
- Soft drinks
- Sweets
- White bread
- Cookies
- Cakes
- Fried foods
- Red meat in excess
- Processed snacks
- Alcohol
These foods spike sugar or increase fat storage.
Exercise for Pre Diabetes

Exercise is one of the strongest tools you have.
1. Walking
Brisk walking for 30 minutes daily helps lower sugar.
2. Aerobic Exercise
Cycling, jogging, swimming.
3. Strength Training
Helps build muscle and increases insulin sensitivity.

- 150 minutes of moderate exercise
- 2 days of strength training
Weight Loss Tips for Pre Diabetes
- Eat smaller portions
- Increase protein intake
- Drink water before meals
- Sleep at least 7 hours
- Avoid emotional eating
- Use slow eating techniques
- Avoid extreme diets
Slow and steady progress works best.
Stress Management
Stress can push sugar levels up. Use these ideas:
- Deep breathing
- Light stretches
- Short breaks during work
- Limiting screen time
- Talking to friends
- Practising gratitude
Reducing stress creates a big difference in sugar control.
Sleep and Blood Sugar Connection
Not sleeping well increases hunger and reduces insulin sensitivity.
Tips for better sleep:
- Keep the room dark
- Avoid caffeine at night
