Yes, it's often possible to see significant improvements or even reverse prediabetes within 6 months through dedicated lifestyle changes, with many people noticing positive shifts in blood sugar (A1c) levels in 3-6 months by losing modest weight (5-7%), increasing physical activity (150 mins/week), and adopting healthier eating habits like reducing sugar and refined carbs, though full reversal timelines vary by individual.
Here are five ways to prevent diabetes or help reverse Type 2 and prediabetes:
For some patients, a return to normal blood sugar levels may come over a few months, while for others, it may take years. "We repeat the A1C test with our prediabetes patients every three or six months, so we can monitor their progress in getting those A1C levels down," Harper says.
Hormones, mainly insulin, keep blood sugar at the right level in the body. But during pregnancy, hormone levels change. Those changes may make it harder for the body to use blood sugar as it should. This makes blood sugar rise.
Not everyone with prediabetes will go on to develop diabetes. Over the short term (three to five years), about 25% of people with prediabetes develop full-blown diabetes. The percentage is significantly larger over the long term. Getting the wake-up call of prediabetes can be very useful.
A normal HbA1c is generally below 5.7% for all adults, but levels naturally tend to rise slightly with age, with upper limits increasing for older adults (e.g., around 6.0-6.5% for those 60+) to avoid hypoglycemia, though specific targets depend on individual health, with 5.7-6.4% indicating prediabetes and 6.5% or higher suggesting diabetes.
The exact cause of prediabetes is unknown. But family history and genetics appear to play an important role. What is clear is that people with prediabetes don't process sugar (glucose) properly anymore. Most of the glucose in your body comes from the food you eat.
High blood sugar during pregnancy can cause problems for your baby while you are pregnant and after you give birth. The effects of high blood sugar for your baby may result in birth defects if you have uncontrolled blood sugars before getting pregnant and during the first trimester of pregnancy.
In fact, if your diabetes is kept under control through proper diet, exercise and medication, it should not play a major role in your ability to conceive. However, if your blood glucose levels are not under control, it can have several negative effects on your fertility as well as your ability to sustain a pregnancy.
Reversing Prediabetes — Is it possible? Yes! “If you've been diagnosed with prediabetes, progressing to diabetes is not a given,” Seymour emphasizes. In addition to taking medications, she says there are other ways to take control.
Warning Signs and Symptoms
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.
Don't let the “pre” fool you. Prediabetes is a serious health condition. People with prediabetes have higher blood sugar than normal, but not high enough yet for a diabetes diagnosis. Prediabetes puts you at increased risk of developing type 2 diabetes, heart disease, and stroke.
Grams of Carbs per Day for Prediabetics
Under 20 to 50 grams of carbohydrates per day: very low-carb ketogenic diet. 130 grams: "Adequate Intake" (the amount considered adequate for most people).
If you discover that you do have prediabetes, remember that it doesn't mean you'll develop type 2, particularly if you follow a treatment plan and make changes to your lifestyle through food choices and physical activity. Even small changes can have a huge impact on delaying or preventing diabetes all together.
Frequent, large spikes can increase long-term health risks, but brief and occasional spikes might even be beneficial. Key Takeaways: Factors beyond food can cause glucose spikes, including dehydration, stress hormones like cortisol, poor sleep, and even sunburn.
Spotting the red flags
Sweets and desserts should be avoided as they may lead to high blood sugar levels.
If you receive a prediabetes diagnosis, you'll need to make lifestyle changes to manage or reverse it. This can be overwhelming. But taking it one step at a time can lead you closer to better health. Without taking action, many people with prediabetes eventually develop Type 2 diabetes.
“Even if you're thin, inadequate physical activity and unhealthy eating can contribute to insulin resistance, a precursor to Type 2 diabetes,” says Ms. Kosak. “Also, things you can't control like age and family history increase your risk, no matter your body size.”
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.
Without taking action, many people with prediabetes could develop type 2 diabetes within 5 years.
Impaired diabetes control: In a 2006 study, sleep duration and quality were “significant predictors” of A1c in 161 patients with type 2 diabetes.
Type 2 Diabetes: A 2012 study of 201 people with type 2 diabetes found that every additional 2,600 steps of walking each day was associated with a 0.2% lower A1c. For reference, 2,600 steps is a little over a mile (about 20 minutes walking at a normal pace).
