Diabetes care: endocrinologist or your own doctor?

Most type 2 diabetes belongs in primary care

This is not a downgrade. A primary care doctor who follows the American Diabetes Association Standards of Care, which are revised every single year, gives excellent diabetes care.

They also handle the blood pressure, cholesterol, kidney and eye checks that actually decide whether diabetes shortens your life. Most people with type 2 diabetes die of cardiovascular disease, not of high glucose, and a clinician who sees the whole picture is often better placed than one who sees only the gland.

What you need is not necessarily a specialist. It is a clinician who is current.

When to ask for an endocrinologist

• Type 1 diabetes, at any age, always
• An HbA1c that will not come down after several medicine changes
• You are on insulin and struggling with doses, or you want an insulin pump or continuous glucose monitor
• Repeated low blood sugars, or lows you can no longer feel coming
• Pregnancy, or planning one, with any kind of diabetes
• The diagnosis itself is unclear, for example a thin adult who looks type 2 but may have LADA, or someone with a strong family pattern suggesting MODY
• Complications progressing despite treatment, in the kidneys, eyes or nerves
• Steroid-induced or post-transplant diabetes, which behaves differently

What good diabetes care looks like

Wherever it happens, guideline-based care includes:

• HbA1c checked twice a year when stable, four times when it is not
• An individual target, not 7 percent for everyone. Older people, and those with heart disease or a history of severe lows, often have a deliberately looser target
• A yearly urine albumin test and eGFR, because kidney disease is silent
• A dilated eye examination every one to two years
• Feet examined at least yearly, more often with neuropathy
• Blood pressure and cholesterol treated properly, which prevents more harm than glucose control alone
• An SGLT2 inhibitor or GLP-1 medicine considered when there is heart disease, kidney disease or heart failure, because those protect organs independently of how much they lower glucose
• Vaccination, including influenza, pneumococcal, COVID and hepatitis B

If your visits are only ever about the glucose number, something is being missed.

Monitoring, and what is worth paying for

Continuous glucose monitors have transformed type 1 diabetes and are increasingly used in insulin-treated type 2. They show patterns that finger-prick testing hides, especially overnight.

In diet-controlled type 2 diabetes the evidence is weaker, and a clinician should say so rather than sell you one. Some people find a short period of monitoring genuinely useful for understanding which meals do what, and then stop. That is a reasonable use.

Time in range, the proportion of the day spent between roughly 70 and 180 mg/dL, is now used alongside HbA1c and often reflects daily life better.

Signs care has fallen behind

Older sulfonylureas or human insulins used first line without a reason such as cost. No urine albumin test in the past year. A refusal to discuss newer medicine classes. Supplements sold in the office for blood sugar. Being told to stop metformin for mild kidney impairment when the guidelines allow it to continue down to an eGFR of 30. Being told to avoid all fruit.

Any of these is a fair reason to seek a second opinion.

Questions worth asking

• What is my personal HbA1c target, and why that number?
• When did I last have a urine albumin test?
• Given my heart and kidney results, should I be on an SGLT2 inhibitor or a GLP-1 medicine?
• What is the plan if this does not work in three months?
• What should I do on a day when I am unwell and not eating?

Finding diabetes care that follows the evidence

Every clinician in our diabetes clinicians list has had their license checked against the national registry, has their board certifications recorded, and has been screened against their public record. We show no patient reviews and no star ratings, and paying for a listing never changes who passes review.
