Diabetes Q & A

What is diabetes?

Diabetes is a chronic health condition that affects how your body processes the sugar from your diet into energy. Normally, your pancreas produces the hormone insulin to regulate sugar (glucose) levels in your bloodstream.  

When you have diabetes, this process doesn’t work the way it should, depending on the type of condition you have.

Type 1 diabetes

Type 1 diabetes is a condition that often develops in childhood due to immune system dysfunction. The immune system mistakenly attacks the pancreas, and it can’t produce the insulin your body needs to regulate blood sugar levels.

Type 2 diabetes

Type 2 diabetes occurs when your body doesn’t make enough insulin or doesn’t use the insulin it produces properly. This condition generally develops due to poor nutrition, unhealthy lifestyle habits, and obesity.


Prediabetes is a condition where your blood sugar levels are high but not high enough to be considered diabetes. Your risk of developing Type 2 diabetes increases significantly if you’re prediabetic.

Rajan Medical Group provides complete diabetes care, including diagnostic testing, customized treatments, and preventive screenings in-office and through telehealth appointments.

How do I know if I have diabetes?

The only way to confirm you have diabetes is through a blood test to evaluate your glucose levels. Rajan Medical Group offers on-site blood tests and other lab work to determine if diabetes is the cause of symptoms like:

  • Blurry vision
  • Mood changes
  • Increased thirst
  • Frequent urination
  • Unintentional weight loss
  • Persistent fatigue
  • Slow-healing sores

Dr. Thiagarajan also recommends that you schedule routine diabetes screenings if you have a family history of the disease, are obese, or have prediabetes. Early intervention lowers your risk for complications like nerve damage, vision loss, and dementia, which uncontrolled diabetes can cause.

How is diabetes treated?

If you have Type 1 diabetes, you need to take insulin daily to keep your blood sugar levels under control. You also need to make diet and lifestyle changes to ensure your sugar levels stay healthy in the long term.

Managing Type 2 diabetes and prediabetes may initially begin with diet improvements, increased exercise, and weight loss to lower your blood sugar levels naturally. If these strategies aren’t enough, you may also need to take medications to prevent diabetes-related complications.

Dr. Thiagarajan also shows you how to check your blood sugar levels at home and can help you schedule follow-up appointments for in-office blood tests. If you have any issues with your diabetes treatment, you can connect with him online through the telehealth platform.
