The time it takes to go from prediabetes to type 2 diabetes varies, but many people develop it within 3 to 5 years without intervention, with some studies showing progression in about 25% of individuals in that timeframe, while others suggest 5-10% progress each year. However, this progression isn't guaranteed, and lifestyle changes like healthy eating and exercise can often reverse prediabetes, delaying or preventing diabetes for years, or even indefinitely.
Many people with prediabetes need to take action now—if they don't, they could develop type 2 diabetes within five years, according to the CDC. Weight loss is a key strategy to reverse prediabetes, but it's important to know that not everyone needs to lose a massive amount of weight, doctors say.
Classic signs and symptoms that suggest you've moved from prediabetes to type 2 diabetes include:
If you have prediabetes, you can lower your risk for developing type 2 diabetes by: Losing a small amount of weight if you have overweight. Getting regular physical activity.
Some of the symptoms of type 1 diabetes and type 2 diabetes are: Feeling more thirsty than usual. Urinating often. Losing weight without trying.
Add aerobic exercise: Strength training and cardiovascular exercise are both crucial for reversing prediabetes. You'll see the best results when you fit both into your weekly workout plan.
Early signs of diabetes often include increased thirst and frequent urination, extreme hunger, fatigue, blurred vision, slow-healing sores, and unexplained weight loss (especially Type 1) or weight gain (Type 2), but Type 2 symptoms can be mild or absent, so regular checkups are key. Tingling in hands/feet, frequent infections (yeast, UTIs), and mood changes can also appear.
Poor sleep quality was related to glucose intolerance in people with prediabetes. C-reactive protein was greater in subjects with prediabetes compared to those with normal glucose tolerance. There was a positive correlation between sleep disturbance and C-reactive protein levels in subjects with prediabetes.
What Does Fatigue in Prediabetes Feel Like? People often describe: Struggling to get out of bed in the morning. Feeling “wiped out” after simple tasks.
Paul Breyer, chief of pediatric endocrinology at Dayton Children's Hospital. “Getting less than six hours of sleep can cause higher blood sugars the following day.” Not only do sleep disturbances cause changes in hormones and diet, but a night of tossing and turning is also linked to poor self-care.
Even people who exercise, eat well and maintain normal weight can develop prediabetes, Dr. Moin notes, as genetic factors play a role. The U.S. Centers for Disease Control and Prevention offers an instant online test Link is external to assess prediabetes risk.
Symptoms of type 2 diabetes often come on slowly. In fact, people can live with type 2 diabetes for years and not know it.
Diabetes symptoms
Toilet - going for a wee a lot, especially at night. Thirsty - being really thirsty. Tired - feeling more tired than usual. Thinner - losing weight without trying to.
How do I check?
The 5-20 Rule
“The general rule for sugar content is choose products with a sugar content of 5% or less of the daily requirement and avoid items in which the amount of sugar is 20% or more of the daily requirement,” Seymour says.
Walking, like other exercise, can help: Lower blood sugar. Increase your body's ability to use insulin better.
But a recent study published in the American Journal of Medicine indicates that physical activity may be most effective at reducing blood glucose and improving insulin sensitivity if it is done later in the day, especially after meals.
Three common signs of diabetes are increased thirst and frequent urination, extreme tiredness, and blurry vision or slow-healing sores, often stemming from high blood sugar levels affecting the body. These symptoms, sometimes called the "Three Ps" (polyuria, polydipsia, polyphagia), can develop slowly in Type 2 diabetes or quickly in Type 1.
Feeling very thirsty. Feeling very hungry—even though you are eating. Extreme fatigue. Blurry vision.
Five common signs of prediabetes include increased thirst/urination, constant fatigue, blurry vision, dark skin patches (acanthosis nigricans), and slow-healing cuts or frequent infections, though prediabetes often has no noticeable symptoms, making early detection key. These signs often signal higher blood sugar levels, indicating your body isn't using insulin effectively.
Some common signs of diabetes are as follows:
Physical symptoms: reduced activity, low energy, tiredness, decreased physical endurance, increased effort to do physical tasks, general weakness, heaviness, slowness or sluggishness, nonrestorative sleep, and sleepiness.
It's not your fault
You've been diagnosed with type 2 diabetes because your body doesn't use insulin well. Because of that, it can't keep your blood sugar at normal levels. There are many factors that can lead to type 2 diabetes.
Thus, weight loss is an important driver of prediabetes remission and, in PLIS, an improvement in insulin sensitivity was critical for prediabetes resolution [5]. Previous analysis from the DPP showed that younger age and insulin secretion at baseline were predictive for remission [8].
You're hungrier or thirstier than normal.
If your body isn't using glucose effectively for energy, you might feel hungrier — even if you're eating more than usual. At the same time, high blood sugar levels can trigger excessive thirst and more frequent trips to the bathroom.
