Diabetes Q & A

What is diabetes?

Diabetes is a common disease that occurs if you have too much glucose, or sugar, in your bloodstream. Normally, your pancreas makes insulin, a hormone that helps guide glucose into your cells so you can get energy from food.

If you have diabetes, you either don't have insulin or your body doesn’t process insulin properly (insulin resistance). When you can't get the glucose out of your blood, you can experience problems including vision loss, kidney damage, and nerve damage. You also increase your risk of infections, strokes, and heart attacks.

If not managed and monitored, diabetes could even be fatal. But, thanks to medical advances, it's now easier to manage your diabetes effectively and stay healthy.

What are the types of diabetes?

The two main forms of diabetes are:

Type 1

People with type 1 diabetes can’t make insulin. Experts believe that Type 1 diabetes is an autoimmune disease that happens when the immune system starts destroying the part of the pancreas (beta cells) that makes insulin.

Type 2

People with type 2 diabetes can make insulin, but over time develop insulin resistance. When left untreated, people with type 2 diabetes can lose beta cells steadily, which increases blood sugar levels even more.

Both forms of diabetes are serious and require customized care from an experienced endocrinologist like Dr. Fishman.

Why do I need to see an endocrinologist for diabetes?

Diabetes means you have an issue with hormones, specifically insulin. As an endocrinologist, Dr. Fishman is an expert in hormones and metabolic health.

She can help you manage your diabetes effectively so you can achieve the best health possible while preventing serious diabetes complications.

How is diabetes treated?

Your treatment can vary depending on the type and severity of your diabetes. You may need glucose-lowering pills, insulin, or non-insulin injections that reduce enhance your body’s ability to process insulin. Dr. Fishman uses the most up-to-date diabetes treatments and technology, such as:

Continuous glucose monitoring

Continuous glucose monitoring uses a tiny sensor that transmits your blood glucose levels to your phone or external receiver. This information can substitute for frequent finger-stick blood glucose checks.

Dr. Fishman also offers remote monitoring, which makes it easy to stay connected with her even when you’re not in the office. This advanced technology allows for a quick response to find the right treatments faster.  

Insulin pumps

Insulin pumps can replace multiple daily insulin injections. Most pumps work by continually delivering tiny doses of insulin and then delivering larger doses as needed at mealtime. 

Dr. Fishman specializes in all aspects of diabetes. Certified in obesity medicine and clinical nutrition support, she offers expert, customized support with weight loss and dietary changes that can help control your diabetes.
