The A1C test measures your average blood sugar level over the past 2 or 3 months. An A1C below 5.7% is normal, between 5.7 and 6.4% indicates you have prediabetes, and 6.5% or higher indicates you have diabetes.
You can use a device called a continuous glucose monitor (CGM). Or you can test your blood sugar at home with a portable electronic device called a blood sugar meter using a small drop of your blood.
The most common symptoms of undiagnosed Type 1 and Type 2 diabetes are: Extreme thirst and a greater need to urinate: As excess glucose (sugar) builds up in the bloodstream, fluid is pulled from the tissues. The loss of fluid makes you thirsty. As a result, you may drink and urinate more than usual.
Fasting blood sugar test
Less than 100 mg/dL (5.6 mmol/L ) is normal. 100 to 125 mg/dL (5.6 to 6.9 mmol/L ) is diagnosed as prediabetes. 126 mg/dL (7.0 mmol/L ) or higher on two separate tests is diagnosed as diabetes.
Many people have type 2 diabetes for years without realising because the early symptoms tend to be general, or there are no symptoms at all.
The symptoms of diabetes include feeling very thirsty, passing more urine than usual, and feeling tired all the time. The symptoms occur because some or all of the glucose stays in your blood and isn't used as fuel for energy. Your body tries to get rid of the excess glucose in your urine.
Blurry vision. Cuts/bruises that are slow to heal. Weight loss—even though you are eating more (type 1) Tingling, pain, or numbness in the hands/feet (type 2)
Transparent and lacking in color
Transparent, colorless urine could also be a sign of some other health disorders, including diabetes and kidney disease, or from taking diuretic medication.
Left untreated, diabetes can lead to heart disease, stroke, nerve and kidney damage, vision loss and more. Even if you have mild blood sugar elevations, you can damage your organs. Diabetes is a common condition.
Overweight, obesity, and physical inactivity
You are more likely to develop type 2 diabetes if you are not physically active and are overweight or have obesity. Extra weight sometimes causes insulin resistance and is common in people with type 2 diabetes.
There is no cure for type 2 diabetes. But it may be possible to reverse the condition to a point where you do not need medication to manage it and your body does not suffer ill effects from having blood sugar levels that are too high.
If type 2 diabetes goes untreated, the high blood sugar can affect various cells and organs in the body. Complications include kidney damage, often leading to dialysis, eye damage, which could result in blindness, or an increased risk for heart disease or stroke.
Untreated diabetes can lead to long-term complications or even death. In people with type 2 diabetes, these complications can include heart disease, kidney damage, peripheral neuropathy (nerve pain), or vision loss. Sometimes, diabetes goes untreated because it hasn't been diagnosed.
Blurry vision, increased urination, feeling hungry, extreme thirst, and finding that you have itchy, dry skin are all warning signs that you could be in the early stages of type 2 diabetes. Some other signs may be harder to pin down.
The short answer is yes, gaining weight with diabetes is possible. People with diabetes indeed often struggle with weight gain due to medications plus a sedentary lifestyle. Lack of exercise can contribute to weight gain, which results in higher blood glucose and unhealthy cholesterol levels.
What does diabetes itching feel like? If you have diabetes, itching can be intense. It's an irritating feeling that makes it hard not to scratch, but scratching can make the itch worse. You can itch anywhere, but if you have nerve damage (neuropathy) associated with diabetes, your lower legs may itch.
What Is Prediabetes? Prediabetes is a serious health condition where blood sugar levels are higher than normal, but not high enough yet to be diagnosed as type 2 diabetes. Approximately 96 million American adults—more than 1 in 3—have prediabetes. Of those with prediabetes, more than 80% don't know they have it.
How can I check my blood sugar at home without a meter? A person may use a lancet to prick their finger. This collects a small blood sample which a person can drop onto a test strip. This test strip will indicate a person's sugar level.
