What are the early signs?

To start, it’s important to pay attention to the signs your body may be giving you. Among the most common are:

• Constant thirst, even after drinking fluids.
• Increased urination, especially at night.
• Fatigue that doesn’t go away, even with adequate rest.
• Changes in vision, such as difficulty focusing or blurred vision.
• Unexplained weight loss or excessive hunger.

These signs may raise questions such as, “How do I know if I have diabetes?” and may indicate that something is wrong with your metabolism. Although they do not confirm the presence of diabetes, they should prompt you to seek a medical evaluation. Remember: early action is the key to preventing future complications.

Why Is It Important to Know?

If left untreated, diabetes can lead to a range of serious complications. Nerve damage, vision problems, and even cardiovascular risks are associated with this metabolic condition.
However, early detection allows for effective treatment that minimizes these risks and significantly improves quality of life.
If you’re wondering, “How do I know if I have diabetes?”, keep in mind that the answer involves more than just identifying symptoms.
It also involves understanding the risk factors and taking proactive steps to obtain a reliable diagnosis.

Who Should Get Screened?

There are certain groups of people who should be particularly alert to the signs. If you’ve ever wondered, “How do I know if I have diabetes?”, be aware that certain risk factors require attention even in asymptomatic individuals. These include:

• Individuals with a family history of the disease.
• People who are overweight or obese.
• People with high blood pressure or high cholesterol levels.
• Women who had gestational diabetes during pregnancy.
• People over 45 years of age, even without obvious symptoms.

If you belong to one of these groups or have associated symptoms, it is essential to seek medical advice and undergo the appropriate tests.

How do I know if I have diabetes? The necessary tests

The answer to the question “How do I know if I have diabetes?” involves undergoing simple, quick, and effective tests that measure blood sugar levels. These tests are conducted by healthcare professionals and provide clear information about your metabolic status.

To diagnose diabetes, the following laboratory tests must be performed and the following results obtained:

• Fasting blood glucose ≥ 126 mg/dl; or
• Classic symptoms + random blood glucose ≥ 200 mg/dl; or
• Blood glucose ≥ 200 mg/dl at 2 hours during an oral glucose tolerance test (OGTT) with 75 g of glucose; or
• Glycated hemoglobin A1c (HbA1c) ≥ 6.5%.

The diagnosis of diabetes in an asymptomatic person should not be based on a single abnormal fasting blood glucose or HbA1c value; it must be confirmed by a second test one to two weeks later.

It is advisable to use a single parameter for the diagnosis of diabetes. However, if fasting blood glucose and HbA1c are measured simultaneously, and both meet diagnostic criteria, the diagnosis is confirmed; but if one result is inconsistent, the abnormal parameter must be repeated in a second test.

There is also the possibility of diagnosing impaired glucose tolerance or identifying categories of increased risk for diabetes, which is based on the following parameters:

• Impaired Fasting Glucose (IFG): fasting blood glucose ≥ 110 and < 126 mg/dl
• Impaired Glucose Tolerance (IGT): blood glucose at 2 hours during the oral glucose tolerance test (OGTT) ≥ 140 and < 200 mg/dL

The diagnosis of gestational diabetes is based on the following results:

• Fasting blood glucose, to be measured at the first prenatal visit, ≥ 92 mg/dL and < 126 mg/dL
• If fasting blood glucose is < 92 mg/dl, an OGTT with 75 g of glucose is performed at 24–28 weeks of gestation. The diagnosis of gestational diabetes is confirmed by one or more of the following values:
  • at 0 hours, blood glucose ≥ 92 mg/dl (or ≥ 5.1 mmol/l);
  • at 1 hour, blood glucose ≥ 180 mg/dl (or ≥ 10.0 mmol/l);
  • at 2 hours, blood glucose ≥ 153 mg/dl (or ≥ 8.5 mmol/l).

What to do after diagnosis?

If the results confirm the condition, don’t panic. Diabetes can be effectively managed with treatment and the right lifestyle changes. For those who have already faced the question “how do I know if I have diabetes” and received a diagnosis, the next step is crucial: follow your doctor’s instructions diligently. After diagnosis, your doctor may recommend:

• Dietary changes, prioritizing high-fiber foods and avoiding refined sugars.
• A regular exercise plan to help control weight and blood glucose levels.
• Medications or insulin, depending on the type of diagnosis.
• Regular follow-up appointments to monitor your metabolic health and prevent complications.

The journey after diagnosis may seem challenging, but with the right support, it’s possible to live a full and healthy life.

How can you prevent or monitor it?

Even if test results do not confirm the presence of diabetes, it is important to take steps to prevent its development. Some strategies include:

1. Maintaining a healthy
   diet Choose vegetables, lean proteins, and whole grains, and reduce your intake of processed foods.
2. Engage in regular
   physical activity Activities such as walking, swimming, or biking help keep your metabolism active and healthy.
3. Getting regular
   checkups Routine exams help detect changes early, especially in people with risk factors.
4. Manage your weight
   Maintaining a healthy weight significantly reduces the chances of developing insulin resistance.

These steps apply both to those who want to prevent the condition and to those who have already been diagnosed and wish to manage it better. Understanding “how to tell if I have diabetes” helps you stay healthy and prevent complications. Adopting healthy habits and seeking medical follow-up are essential steps.
