What a diabetes doctor does and when you need one

A diabetes doctor — usually called an endocrinologist — is a doctor who specializes in conditions affecting your hormones and metabolism, including diabetes. They manage blood sugar control, adjust medications, and help prevent or slow complications like kidney disease, nerve damage, and heart problems. You may see an endocrinologist alongside your primary care doctor, or instead of one, depending on how complex your diabetes is.

You might need a diabetes specialist if your blood sugar stays hard to control, if you take insulin, if you have had diabetes for many years, if you are pregnant with diabetes, or if you have developed complications. Some people manage type 2 diabetes well with their primary care doctor alone. Others benefit from a specialist's deeper knowledge of insulin dosing, newer medications, or managing diabetes alongside other conditions.

Not every area has endocrinologists available, and wait times can be long. If a specialist is not reachable, your primary care doctor, a nurse practitioner with diabetes training, or a certified diabetes educator can often provide much of the same guidance.

Key Takeaways

  • Endocrinologists are doctors trained specifically in diabetes and hormone conditions, and they adjust medications and help prevent complications.
  • You can find diabetes doctors through your insurance provider's directory, your primary care doctor's referral, or the American Diabetes Association's provider search tool.
  • Many diabetes specialists require a referral from your primary care doctor before they will see you, so ask your doctor to send one.
  • If you cannot reach an endocrinologist, a certified diabetes educator or nurse practitioner with diabetes training can teach you how to manage your blood sugar day to day.
  • Bring your blood sugar log, current medications, and a list of questions to your first appointment so the doctor can understand your situation quickly.

How to find a diabetes doctor in your area

Start with your insurance company's provider directory. Log into your insurance website or call the number on your insurance card and ask for endocrinologists in your network. Ask which ones are currently taking new patients — some specialists have closed practices to new referrals. Write down their office phone numbers and addresses.

Your primary care doctor can also refer you. Tell your doctor you want to see a diabetes specialist and ask them to send a referral. The specialist's office will contact you to schedule, or your doctor's office may do the scheduling for you. A referral from your primary care doctor often moves you higher on the waiting list.

The American Diabetes Association website has a "Find Care" tool where you can search by zip code for endocrinologists and certified diabetes educators near you. The tool is free and does not require you to log in. You can also call 1-800-DIABETES to ask for referrals by phone.

If you live in a rural area or a place with few endocrinologists, ask your primary care doctor about telehealth visits with a diabetes specialist. Some endocrinologists see patients by video call, which can shorten wait times and eliminate travel.

What to expect at your first appointment

Bring your blood sugar log or the data from your glucose meter if it stores readings. If you use a continuous glucose monitor, bring that device or the app on your phone. Bring a list of all your current medications, including doses and how often you take them. Bring any recent lab results — your A1C, kidney function, and cholesterol numbers help the doctor understand your diabetes control.

Write down three to five questions before you go. Examples: "Should I be on insulin?" "Why is my blood sugar high in the morning?" "What should I eat?" "How do I prevent kidney problems?" Having questions written down means you will not forget them when you are nervous or the appointment is short.

The first visit is usually longer than follow-up visits. The doctor will ask about your diabetes history, your daily routine, what you eat, whether you exercise, and whether you have had any complications. They will examine you and may order blood work. They will explain their plan for managing your diabetes and may change your medications.

At the end of the visit, ask when you should come back and how to reach the office if you have questions before then. Ask whether the office has a nurse line you can call, or whether you should email. Some offices use patient portals where you can message the doctor's team.

Understanding referrals and insurance requirements

Many endocrinologists require a referral from your primary care doctor before they will schedule you. A referral is a formal request from one doctor to another. Your primary care doctor sends it to the specialist's office, usually by fax or through an electronic system. The referral tells the specialist that your primary care doctor thinks you need specialized care.

Some insurance plans require a referral for you to see a specialist. If you see a specialist without a referral when your plan requires one, you may have to pay the full cost of the visit. Before you schedule, call the specialist's office and ask: "Do you require a referral?" and "Does my insurance plan require a referral?" If the answer to either is yes, contact your primary care doctor and ask them to send one.

After the referral is sent, the specialist's office usually calls you within a few days to schedule. If you do not hear from them within a week, call the specialist's office yourself and confirm they received the referral. Referrals sometimes get lost in fax machines or email systems.

When to see a diabetes doctor versus other specialists

An endocrinologist manages your overall diabetes, adjusts insulin and other medications, and watches for complications. This is the main diabetes specialist.

A certified diabetes educator (CDE) is a nurse, dietitian, or other health professional trained to teach you how to manage diabetes day to day — how to check your blood sugar, what to eat, how to take medications, and how to recognize low blood sugar. Many people see a CDE for one or more visits to learn the basics, then see an endocrinologist for medication adjustments. Some CDEs work in the endocrinologist's office.

A registered dietitian specializes in food and nutrition. If your diabetes is hard to control or you are not sure what to eat, a dietitian can create a meal plan for you. Some insurance plans cover dietitian visits if your doctor refers you.

A nurse practitioner or physician assistant with diabetes training can manage diabetes much like an endocrinologist in some cases, especially if your diabetes is straightforward. They may be easier to reach and have shorter wait times than endocrinologists in your area.

If you cannot reach an endocrinologist, ask your primary care doctor whether they feel confident managing your diabetes, or whether they can refer you to a nurse practitioner or CDE instead.

What to bring and how to prepare for visits

Bring your insurance card and photo ID to every visit. Bring a notebook or your phone to write down what the doctor tells you — you will forget details after you leave. Bring your blood sugar log or meter. Bring a list of all your medications with doses. Bring recent lab results if you have them.

If you take insulin, bring your insulin pens or vials and your injection devices so the doctor can watch you inject and make sure your technique is correct. If you use a continuous glucose monitor or insulin pump, bring that device.

Wear loose clothing so the doctor can check your blood pressure and examine your feet and legs. Diabetes can damage nerves and blood vessels in your feet, so the doctor will check for sores, numbness, and circulation problems at every visit.

If you have questions about your medications, your diet, or your blood sugar patterns, write them down before the visit. If you have been having low blood sugar episodes or high readings, write down when they happen and what you were doing. This information helps the doctor adjust your treatment.

How often to see a diabetes doctor and what happens between visits

Most people see an endocrinologist two to four times a year. If your diabetes is newly diagnosed or hard to control, you may see the doctor more often at first — sometimes every month until your blood sugar is stable. Once your diabetes is well controlled, you may see the doctor once or twice a year.

Between visits, check your blood sugar as your doctor recommends. Keep a log or use your meter's memory to track readings. If you notice patterns — high readings at certain times, low readings after exercise, or readings that do not make sense — write them down and bring them to your next visit.

If your blood sugar goes very high or very low, or if you have symptoms like blurred vision, numbness in your feet, or chest pain, contact your doctor or go to an emergency room. Do not wait for your next scheduled visit.

Some endocrinologists' offices call you between visits to check on how you are doing, especially if you recently started a new medication. If you do not hear from them and you have questions, call the office. Many offices have a nurse line where you can ask questions without waiting for an appointment.

Frequently Asked Questions

Do I need a referral to see an endocrinologist?

Many endocrinologists require a referral from your primary care doctor, and some insurance plans require one for you to be covered. Call the specialist's office and your insurance company to find out. If a referral is needed, ask your primary care doctor to send one — it usually takes a few days.

What if I cannot afford to see a diabetes specialist?

Ask your primary care doctor whether they can manage your diabetes, or whether they can refer you to a nurse practitioner or certified diabetes educator instead. Some community health centers offer diabetes care on a sliding fee scale based on income. Call 211 to find low-cost clinics in your area.

How long does it take to get an appointment with an endocrinologist?

Wait times vary widely by location and how busy the practice is. In some areas you can get in within weeks; in others it may take several months. Call the office and ask how long the wait is before you ask for a referral. If the wait is very long, ask your primary care doctor about other options.

Can I see a diabetes doctor by video call?

Some endocrinologists offer telehealth visits, especially for follow-up appointments. Ask when you call to schedule whether video visits are available. Telehealth can be faster and easier if you live far from the office or have trouble traveling.

What should I do if I do not get along with my diabetes doctor?

You can see a different doctor. Ask your primary care doctor for another referral, or search the American Diabetes Association's provider tool for someone else in your network. You deserve a doctor you trust and who listens to you.
