what doctor should I see for diabetes



QUESTION:


I am 38 years old and have diabetes. I currently live in the Middle East and receive medicine from my family doctor. My blood sugar has come down but is still not under control. Should I see a specialist, and what type of doctor should I consult?




Quick Answer


A family or primary-care doctor can manage many people with type 2 diabetes. Because your glucose has improved but remains above target, ask for a treatment review and consider an endocrinologist or diabetologist—a doctor who specializes in diabetes and hormone disorders. A specialist is particularly useful when the diabetes type is uncertain, HbA1c remains high despite treatment, insulin is being considered or adjusted, glucose fluctuates widely, complications are present, or other medical conditions make treatment complex.



Answer by Dr. Albana Greca, MD, MMedSc


Hello,


The specialist is an endocrinologist or diabetologist. Continue seeing your family doctor while both coordinate care.


Can a Family Doctor Manage Diabetes?


Yes. Primary care can manage uncomplicated type 2 diabetes, prescribe medicine, monitor HbA1c and cardiovascular risk, and arrange kidney and eye screening. What matters is regular review and treatment adjustment when targets are not met.


When Should You See an Endocrinologist?


A referral is reasonable when:



  • HbA1c remains above your individualized goal despite following the treatment plan

  • Several medicines have been tried without adequate control

  • Insulin needs to be started, intensified or simplified

  • Glucose varies widely or you have repeated hypoglycemia

  • The diagnosis of type 1, type 2 or another diabetes type is uncertain

  • You have kidney disease, nerve damage, foot wounds, eye disease or another complication

  • Steroids or another medical condition are making glucose difficult to control

  • You need diabetes technology such as continuous glucose monitoring or an insulin pump


Ask for a referral to endocrinology, diabetes and metabolism, or a diabetes clinic.


What Does “Not Under Control” Mean?


Do not judge control from one reading. Ask for your HbA1c, which reflects roughly two to three months. A common adult goal is below 7%, but targets differ.


Common glucose targets for many adults are approximately:



  • Before meals: 80–130 mg/dL or 4.4–7.2 mmol/L

  • One to two hours after starting a meal: Below 180 mg/dL or 10.0 mmol/L


These are general targets. See our glucose target guide and HbA1c guide.


Which Tests Should Be Reviewed?


You do not need every test before referral. Useful records include:



  • HbA1c and recent fasting or home glucose readings

  • Kidney function, including eGFR and urine albumin-to-creatinine ratio

  • Cholesterol and triglycerides

  • Blood pressure and weight history

  • Liver tests when clinically appropriate

  • Vitamin B12 with long-term metformin or anemia or numbness

  • Additional tests for diabetes type when the clinical pattern is unusual


An oral glucose-tolerance test is not routinely needed after diabetes is established. See our testing guide.


What to Bring to the Appointment



  • All prescription medicines, supplements and their doses

  • Recent laboratory reports

  • Your glucose meter or written glucose record

  • Notes showing whether readings were fasting or after meals

  • A list of low-glucose episodes and other symptoms

  • Questions about food, exercise, medicine effects and treatment cost


Do not change or combine medicines before review.


Other Helpful Professionals


A diabetes educator and dietitian can help with monitoring, medicines and culturally suitable meals. Eye, foot, kidney or heart specialists may be added when screening finds a problem.


Could Another Condition Be Raising Your Sugar?


Infection, stress, poor sleep, inactivity, steroids or another medicine may raise glucose. The old division into a “first disease” and an “underlying disease” is inaccurate; the clinician should review possible contributing factors.


When High Blood Sugar Needs Urgent Care



Seek urgent medical advice for repeated glucose around 250–300 mg/dL or higher, especially with increasing thirst, frequent urination, weakness, fever or infection. Seek emergency care for vomiting, inability to keep fluids down, deep or difficult breathing, severe dehydration, confusion, unusual drowsiness, fruity-smelling breath or moderate-to-large ketones.



Do not wait for a routine appointment when acutely ill. Follow your sick-day plan and do not stop insulin independently.


Your Next Step


Book a family-doctor review, request your latest HbA1c and screening results, and ask for an endocrinology referral. Continue prescribed medicine until reviewed. The aim is to identify why control remains inadequate and adjust medicine, food, activity and monitoring. See our control guide.
