Have you heard the term “prediabetes” and aren’t sure what it means exactly? If so, you might also be wondering how you can tell if you have an increased risk of developing this condition—so continue reading to learn what prediabetes is and what the warning signs are.
Along with a healthcare provider’s evaluation, an HbA1c test may help you find out if you have prediabetes. You can easily check your A1c levels from the comfort of home with our at-home HbA1c test.
Prediabetes occurs when your blood sugar levels are higher than normal, but not high enough for a type 2 diabetes diagnosis. As a result, prediabetes means you’re more likely to develop diabetes if your blood sugar gets too high Additionally, the high glucose levels associated with prediabetes can start damaging your blood vessels, heart, and kidneys.
A healthcare provider may diagnose you with prediabetes if you have:
Having a diagnosis of prediabetes doesn’t mean that developing diabetes is inevitable. It just means you have to watch out for the warning signs of prediabetes—and take steps to keep your blood sugar levels in check.
In someone who doesn’t have prediabetes, their body digests their food and the sugar enters their bloodstream. Their pancreas makes insulin, which circulates through their blood. The insulin then allows the sugar to enter their cells, which lowers blood sugar levels.
If you have prediabetes, the process doesn’t work this way. Instead, your pancreas either doesn’t make enough insulin or your cells become resistant to it (insulin resistance). As a result, the sugar in your body doesn’t fuel your cells. It simply builds up in your bloodstream, causing high blood sugar.
You may be looking for some clear warning signs of prediabetes, but this condition typically doesn’t produce any immediate signs or symptoms. That’s why an estimated 8 out of 10 people with prediabetes don’t even know they have it.
However, some people experience at least one symptom of prediabetes. You may notice darkened, velvety bands or patches of skin on the following body parts:
The medical term for this skin issue is acanthosis nigricans, and it suggests that you have too much insulin in your blood.
Although you may not have prediabetes symptoms, you may notice symptoms if you are developing diabetes. Symptoms of type 2 diabetes include:
It’s a good idea to make an appointment with your healthcare provider if you start to notice these diabetes symptoms and suspect you may be developing type 2 diabetes, especially if you’re at a higher risk for prediabetes or diabetes. Your provider can help you determine whether your blood sugar levels are outside the normal range. They may recommend you take an A1c test, which you can do from the convenience of home with the Everlywell at-home HbA1c test.
When it comes to prediabetes risk factors, you need to be vigilant if diabetes runs in your family. This is especially true if a parent or a sibling has diabetes. But a family history of diabetes isn’t the only risk factor for developing prediabetes. Here are some others:
The main concern about prediabetes is that it can develop into type 2 diabetes. Unmanaged diabetes can contribute to certain health issues, including:
While these issues can occur with type 2 diabetes, proactively managing your blood sugar levels can help prevent them. (Helpful tip: consider learning what medications can raise blood sugar levels and speak with your healthcare provider about their recommendations related to prescriptions you’re taking.)
Several lifestyle changes can often stop prediabetes from progressing to type 2 diabetes:
In addition to these lifestyle changes, consider taking a look at what you can change in your diet. Here are a few tips on how to lower blood sugar naturally from a dietary perspective that can potentially help:
If you’re wondering if you have prediabetes, speak with your healthcare provider to learn what next steps they recommend.
One option for testing and monitoring blood sugar levels over time is a glycated hemoglobin (A1c) test, which indicates your average blood sugar level over the past 2-3 months. The test measures the percentage of the hemoglobin in your red blood cells that are attached to sugar from your bloodstream.
This is a test you can take at home with our at-home HbA1c Test. Taking the test is easy: you just collect a small sample of blood via a simple finger prick, and ship the sample to a lab for analysis (a prepaid shipping label is included with the kit).
In addition to an A1c test, you can also learn more about your glucose levels with a fasting blood sugar test or an oral glucose tolerance test. Your healthcare provider can let you know if they suggest any of these blood glucose level tests for you.
If test results indicate you have prediabetes, your healthcare provider may recommend that you have your A1c levels retested every year. If this is the case, the Everlywell HbA1c Test can be a quick and simple way to check your level from the convenience of home.
