Type 2 Diabetes Diagnosis and Treatment

Could you have type 2 diabetes? 

Are you experiencing symptoms such as ongoing fatigue, increased thirst or frequent urination? You’re not alone. Type 2 diabetes is one of the most common chronic conditions in the United States. 

Whether you’re concerned about your own health or a loved one’s, understanding how type 2 diabetes is diagnosed and treated can help you take the next step with confidence. 

What is type 2 diabetes? 

Type 2 diabetes is a chronic condition that affects how the body uses insulin to regulate blood sugar. Over time, the body becomes resistant to insulin, causing glucose levels in the blood to rise. Without treatment, high blood sugar can increase the risk of serious health complications. 

How is type 2 diabetes diagnosed? 

If your health care provider suspects type 2 diabetes, diagnosis typically begins with a review of your medical history, a physical exam and blood testing. 

Your provider may ask about: 

  • Symptoms you’re experiencing and when they began 
  • Personal and family medical history 
  • Other health conditions that may affect blood sugar 

During the physical exam, your provider will usually check your weight and blood pressure. Blood tests are then used to confirm whether diabetes or prediabetes is present. 

What blood tests are used to diagnose type 2 diabetes? 

Blood tests measure the level of glucose, or sugar, in your blood. Some tests require fasting. Your provider will let you know how to prepare. 

Hemoglobin A1c (HbA1c) test 

Shows your average blood sugar level over the past two to three months. 

  • Normal: Below 5.7% 
  • Prediabetes: 5.7% to 6.4% 
  • Diabetes: 6.5% or higher 

Fasting is not required. 

Random blood sugar test 

Can be done at any time. 

  • 200 mg/dL or higher, along with symptoms such as excessive thirst or frequent urination, may indicate diabetes 

Fasting blood sugar test 

Done after not eating for eight to 10 hours. 

  • Normal: Below 99 mg/dL 
  • Prediabetes: 100 mg/dL to 125 mg/dL 
  • Diabetes: 126 mg/dL or higher 

Oral glucose tolerance test (OGTT) 

Measures how the body processes sugar after fasting and drinking a sweet liquid. 

  • Normal: 140 mg/dL or below 
  • Prediabetes: 140 mg/dL to 199 mg/dL 
  • Diabetes: 200 mg/dL or higher 

After diagnosis, your provider may order additional tests to confirm type 1 vs. type 2 diabetes and evaluate your overall health. 

What are the treatment options for type 2 diabetes? 

Being diagnosed with type 2 diabetes can feel overwhelming. With appropriate care, many people are able to manage their condition and live well. 

Treatment plans are personalized and may include one or more of the options below. 

Lifestyle-based treatment 

Healthy habits are the foundation of type 2 diabetes care. Changes to eating patterns, physical activity and weight management can improve blood sugar control. Your provider will guide recommendations based on your needs. 

Blood sugar monitoring 

Monitoring blood sugar helps determine how well your treatment plan is working. Your provider will recommend how and when to check blood sugar based on your diagnosis and medications. 

Medication 

Many people with type 2 diabetes need medication to help manage blood sugar levels. 

Medication options may include: 

  • Metformin, which is often the first medication prescribed to help lower blood sugar 
  • GLP-1 receptor agonists, injectable or oral medications that help improve blood sugar control and may support weight loss 
  • Other oral or injectable diabetes medications, depending on your health needs 
  • Insulin, which may be needed if other treatments do not adequately control blood sugar 

Your provider will choose medications based on factors such as blood sugar levels, overall health, treatment goals and how your body responds to therapy. 

Ongoing medical care 

Regular follow-up visits are an important part of treatment. These visits allow your provider to: 

  • Monitor blood sugar control 
  • Adjust medications if needed 
  • Screen for diabetes-related health concerns 

Without proper management, type 2 diabetes can increase the risk of heart disease, kidney disease, nerve damage and vision problems. 

Can type 2 diabetes be reversed? 

Type 2 diabetes can sometimes be managed to the point where blood sugar levels return to normal without medication. This is often called remission. Achieving remission typically requires long-term lifestyle changes and ongoing medical monitoring. 

Managing type 2 diabetes is a team effort 

At Banner Health, type 2 diabetes care is collaborative. Your care team may include primary care providers, endocrinologists, dietitians, pharmacists and diabetes educators who work together to support your treatment plan.
