Prediabetes in San Antonio

When your blood sugar starts to rise, you may not feel any different. Many people with prediabetes feel completely fine, which can make it easy to miss.

Prediabetes is a warning sign that your body is starting to have trouble managing sugar. Without changes, it can lead to type 2 diabetes over time.

If you’re concerned about prediabetes in San Antonio, understanding what it is and how it develops can help you take steps early, often before more serious problems begin.

Your body uses insulin to move sugar, called glucose, from your bloodstream into your cells, where it’s used for energy. With prediabetes, that process becomes less effective. This usually happens in one, or both, of these ways:

• Your body doesn’t make enough insulin
• Your cells stop responding to insulin properly, known as insulin resistance

Over time, even slightly high blood sugar can damage blood vessels and raise your risk for other health problems.

Prediabetes reflects real changes already happening in your body. Even before type 2 diabetes develops, higher-than-normal blood sugar has been linked to:

• Heart disease
• Stroke
• Blood vessel damage

Some factors make it harder for your body to manage blood sugar effectively. Excess weight, especially around the abdomen, increases your risk. Prediabetes also becomes more likely if you:

• Are over age 35
• Have a family history of type 2 diabetes
• Are not physically active
• Have high blood pressure
• Had gestational diabetes during pregnancy
• Have abnormal cholesterol
• Have polycystic ovary syndrome (PCOS)
• Have sleep apnea or other sleep disorders

Some groups may have a higher risk, including African American, Hispanic/Latino, Native American, Asian American, and Pacific Islander individuals.

Prediabetes symptoms are often mild and easy to miss. Some people may experience:

• Increased thirst
• More frequent urination
• Fatigue
• Blurred vision

Another sign is a condition called acanthosis nigricans. This shows up as darkened or thickened skin, often around the neck, armpits, or groin, and is indicative of insulin resistance.

Prediabetes is diagnosed with simple blood tests that show how your body handles sugar. Because symptoms are often mild, testing is the most reliable way to know for sure.

These are the standard diagnostic ranges for prediabetes:

A1C: 5.7% to 6.4%

The hemoglobin A1C test shows your average blood sugar over the past 2 to 3 months. This helps give a broader view of how your levels have been trending over time.

Fasting Blood Sugar: 100–125 mg/dL

This test is done after you haven’t eaten for at least 8 hours. It shows how well your body keeps blood sugar in a normal range when you’re not actively digesting food.

2-Hour Oral Glucose Tolerance Test: 140–199 mg/dL

After fasting, your blood sugar is checked, then you drink a sugary solution. Your levels are tested again after 2 hours to see how well your body brings sugar back down.

In many cases, blood sugar levels can improve or move lower to a normal range with consistent changes.

Lifestyle modifications remain the foundation of treatment. Modest weight loss and regular physical activity help your body use insulin more effectively. The result is better blood sugar control and a lower risk of developing type 2 diabetes.

Food choices also matter, and a balanced diet can go a long way. Try to include:

• Vegetables and fruits
• Whole grains
• Lean proteins like fish, poultry, and beans
• Healthy fats, such as nuts and olive oil

It also helps to limit:

• Sugary drinks
• Highly processed snacks
• Refined carbohydrates like white bread
• Large portions of food

Prediabetes often occurs alongside high blood pressure and high cholesterol. So, addressing these together helps reduce your overall cardiovascular risk.

In some cases, medication such as metformin may be recommended to help decrease your risk of developing type 2 diabetes. Metformin works by lowering glucose production in the liver and improving insulin sensitivity. Taking the medication is more common if you:

• Are under age 60
• Have a BMI of 35 or higher
• Have a history of gestational diabetes

Many people are able to stabilize, or even improve, their blood sugar. It’s worth scheduling a visit if you:

• Have risk factors for diabetes
• Haven’t been screened
• Have already been told you have prediabetes
• Want help creating a plan that works for you

Prediabetes doesn’t always cause symptoms, but it can still affect your health over time. The good news is that early action can make a real difference.

If you’re at risk or haven’t been tested, schedule an appointment to check your blood sugar and build a plan that works for you.

1. Is prediabetes serious?

Prediabetes raises your risk of type 2 diabetes, heart disease, and stroke. But it’s also a stage where small changes can make a real difference.

2. Can prediabetes be reversed?

In many cases, blood sugar levels can improve with weight loss, regular activity, and healthy eating habits.

3. Can I improve prediabetes without medication?

Yes. Lifestyle changes are often enough to help lower blood sugar and reduce your risk of type 2 diabetes.

4. What is the A1C for prediabetes?

An A1C of 5.7% to 6.4% falls in the prediabetes range.

5. How often should I be tested?

If you have prediabetes, testing is usually recommended at least once a year. Your doctor may check more often if your levels are close to the diabetes range.
