In short
- It is an assessment and a conversation with a hormone and diabetes specialist, not a treatment in itself.
- A first appointment often decides which tests are needed rather than giving an immediate diagnosis.
- Hormone conditions are usually managed over time, so follow-up and monitoring are part of the picture.
- You should leave with a clear, shared plan and know who to contact if things change.
A plain-English summary. The detail — including risks and recovery — is below.
At a glance
A general guide. Your specialist will give you advice for your situation.
Expert assessment of symptoms or abnormal results
Using a routine clinic appointment for an emergency such as suspected diabetic ketoacidosis or adrenal crisis, which need urgent care.
You discuss your history, may be examined, and review any results. Together you agree the next steps.
A clear, shared plan and a clinic letter to you and your GP.
You discuss your history, may be examined, and review any results. Together you agree the next steps.
You leave with a plan: tests to arrange, treatment to start or change, and advice. You can carry on as normal.
Any tests are done and results come back; you usually receive a clinic letter summarising the plan.
Results are reviewed, treatment adjusted if needed, and longer-term monitoring is arranged where appropriate.
What happens at an endocrinology and diabetes consultation?
Endocrinology is the study of hormones, the chemical messengers that control things like growth, metabolism, blood sugar, salt balance, mood and fertility. An endocrinologist is a doctor who diagnoses and treats problems with the glands that make these hormones, such as the thyroid, pituitary and adrenal glands, as well as diabetes and bone conditions.
You might be referred because you have symptoms that suggest a hormone problem, or because a blood test has come back abnormal. At the appointment the specialist takes a careful history, examines you if needed, reviews any results, and explains what they think is going on. Often the first visit is about deciding which tests are worth doing, rather than reaching a firm diagnosis straight away.
A consultation is a conversation and an assessment, not a treatment in itself. Many hormone conditions are managed over time, so the appointment usually ends with a plan: tests to arrange, treatment to start or adjust, lifestyle advice, and when to be seen again. You should expect to leave understanding the plan and the reasons behind it.
Types, options & approaches
There may be different ways to do this. The right approach depends on the clinical question and your circumstances.
Options at a glance
These are the main approaches described in this guide. The right option depends on the diagnosis, your goals and what your clinician thinks is safe.
History and discussion
The specialist asks about your symptoms, medical and family history, medicines and how the problem affects you, which is often the most important part.
Examination
A focused physical examination if relevant, for example checking the thyroid, blood pressure, weight, or signs of a hormone imbalance.
Review of results
Looking at any blood tests, scans or previous letters you bring or that have been sent, to make sense of the picture.
Tests and plan
Deciding which further tests (blood tests, dynamic hormone tests or scans) are worthwhile, and agreeing treatment, lifestyle advice and follow-up.
Preparing for your appointment
- Bring an up-to-date list of all your medicines, including doses, plus any supplements, the contraceptive pill or HRT.
- Bring copies of recent blood tests, scans or clinic letters if you have them.
- If you have diabetes, bring your blood glucose records or monitor and details of your devices.
- Have any blood tests you were asked for done a week or two beforehand so results are ready.
- Write down your main symptoms, when they started, and your top questions or worries.
- Note any family history of thyroid, diabetes, hormone or autoimmune conditions.
- Consider bringing someone with you to help remember the discussion.
What happens
A first appointment usually lasts around 20 to 40 minutes. The specialist starts by asking about your symptoms, your general health, your medicines and your family history, and how the problem is affecting your life. This history often gives the most useful clues.
They may examine you, for example feeling your thyroid, checking your blood pressure and weight, or looking for signs of a hormone imbalance. They will go through any test results you bring or that have been sent. For diabetes, they will review your blood sugar control, medicines and the checks that protect against complications.
The appointment usually ends with a shared plan: which tests (if any) are needed, whether to start or change treatment, lifestyle advice, and when you will be seen again. You should normally receive a letter summarising the discussion and plan, often copied to your GP.
Is this appointment right for me?
A good consultation should explore whether it's the right choice for you now — including reasons to wait or consider something else.
May not be suitable if…
- Using a routine clinic appointment for an emergency such as suspected diabetic ketoacidosis or adrenal crisis, which need urgent care.
- Expecting a definite diagnosis when the problem clearly needs tests over time first.
- Seeking specialist input when the issue is better handled by your GP or a different specialty.
- Relying on a consultation alone without arranging the tests that were recommended.
Delay or rearrange if…
- You are acutely unwell and need urgent rather than routine assessment.
- Key results or previous letters are not yet available and would change the discussion.
- Requested blood tests have not been done, so there is nothing new to review.
- You cannot attend or engage fully (for example due to an unrelated acute illness).
Alternatives to discuss
- Initial assessment and tests by your GP, with referral only if needed.
- A different specialty if symptoms point elsewhere.
- A telephone or video consultation where a physical examination is not essential.
- Watchful waiting with repeat tests if early results are borderline.
Before you decide
Use this as a shared-decision checklist. The aim is not just “can this be done?”, but whether it is right for you, now, with the risks and alternatives clearly understood.
What matters most to me?
Think about symptoms, daily life, work, caring responsibilities, sport, fertility, travel, appearance and anxiety — the right choice depends on your priorities, not just the medical facts.
What are all my options?
Ask about waiting, monitoring, medicines, rehabilitation, a smaller or larger procedure, a different test, NHS referral, or a second opinion where that would help.
What would make me pause?
Active infection, pregnancy, unstable medical problems, smoking, medicines that increase bleeding, poor support at home, or feeling pressured are all reasons to slow down and get tailored advice.
What happens if I do nothing today?
For some problems, waiting is safe; for others, delay can make treatment harder. A good consultation should explain the trade-off in plain English.
Benefits
- Expert assessment of symptoms or abnormal results
- A clear explanation of what is, or is not, likely to be wrong
- A sensible plan for any tests, avoiding unnecessary ones
- Treatment started or adjusted with the reasons explained
- A written summary and plan, usually shared with your GP
Risks & complications
- Not getting a firm diagnosis at the first visit, as more tests are often needed
- Feeling there was a lot to take in during a short appointment
- Being asked to have further tests before any decisions are made
- Uncertainty while waiting for results
- Disagreement or confusion if previous results or letters are not available
- Anxiety raised by discussing possible diagnoses
- Being referred on to another specialty if the problem lies elsewhere
- An urgent or serious problem being identified that needs prompt action
- Important information being missed if key history or results are not shared
The main pitfall is expecting an instant diagnosis. Hormone problems often need tests over time, and a good consultation may end with a plan to investigate rather than a definite answer. Ask what the specialist thinks the likely causes are, what the tests will and will not show, and when you should expect clarity.
Published figures to discuss
A consultation is a conversation and assessment, so meaningful complication rates do not apply. The main uncertainties are diagnostic rather than physical, and depend on the condition being investigated, so we describe them qualitatively rather than with figures.
| Figure | Reported range | How to interpret it | Source / confidence |
|---|---|---|---|
| Physical complication from the consultation itself | Very low | Most of the appointment is history, examination, blood-test review and planning. | Diabetes UK — Diabetes health checks (annual review)diabetes.org.ukSource-linked context |
| Borderline or misleading hormone result | Common | Hormones vary with time of day, illness, stress, medicines, pregnancy and laboratory method. Repeat or dynamic testing is often appropriate. | Guide sourcesClinical context |
| Urgent endocrine presentation | Clinically important | Adrenal crisis, diabetic ketoacidosis, severe hypoglycaemia, thyroid storm, myxoedema coma and hypercalcaemic crisis need emergency care, not routine clinic. | Guide sourcesClinical context |
| Over-investigation of incidental findings | Recognised | Pituitary, thyroid and adrenal incidentalomas need structured risk assessment rather than reflexive repeated scans and tests. | Diabetes UK — Diabetes health checks (annual review)diabetes.org.ukSource-linked context |
These are literature figures, not a personalised prediction. Your own risks and likely benefits depend on your circumstances, your health, and how your care is carried out and followed up.
What happens afterwards
There is nothing to recover from after a consultation. What matters afterwards is understanding the plan, completing any tests, and knowing when you will be seen or contacted again.
- Leaving with a plan rather than an immediate diagnosis
- Needing to arrange and wait for further tests
- Receiving a clinic letter summarising the discussion
- Having a follow-up appointment to review progress
Aftercare
- Arrange any tests that were requested as soon as you can.
- Start or adjust any medicines exactly as advised, and ask if you are unsure.
- Read your clinic letter and check it matches your understanding; query anything that looks wrong.
- Follow any lifestyle advice (for example around diet, weight, alcohol or activity).
- Note any new or worsening symptoms to mention at follow-up.
- Make sure you know who to contact about results and the next appointment.
- Up-to-date medicines list (including pill, HRT, supplements)
- Recent blood tests, scans and clinic letters
- Blood glucose records and devices if you have diabetes
- Any requested blood tests done beforehand
- Your main symptoms and questions written down
- Contact details for results and queries
⚠ Get urgent help if…
- Severe or rapidly worsening symptoms that cannot wait for the next appointment
- If you have diabetes: very high or very low blood sugars, vomiting, drowsiness or signs of diabetic ketoacidosis, which need urgent care
- Severe headache with vision changes, especially with a known pituitary problem
- Chest pain, palpitations, severe breathlessness or collapse
- If you take steroid replacement: any severe illness, vomiting or collapse (possible adrenal crisis)
- Low mood with thoughts of self-harm, which needs urgent help
Who to contact: your clinician, clinic or test provider first (keep their number to hand). For urgent advice when you can't reach them, call NHS 111. In an emergency, call 999.
General guidance — it doesn't replace the specific advice your specialist gives you.
Results & realistic expectations
A good consultation leaves you understanding what the specialist thinks is going on, what will be done to confirm or rule it out, and what the plan is. For some people that is reassurance; for others it is the start of investigation or treatment.
A consultation cannot, by itself, guarantee a diagnosis or a particular outcome. Hormone conditions often reveal themselves over time and through testing, and plans may change as results come in. The value of the appointment is in expert assessment and a sensible, shared plan, not in instant certainty.
Many hormone and diabetes conditions are long-term and need ongoing review, so a plan made now may be adjusted as your symptoms, results or circumstances change. Even reassuring assessments may need revisiting if new symptoms develop, which is why follow-up arrangements matter.
Related tests, treatments or support
A consultation is often combined with blood tests, and sometimes dynamic hormone tests or scans, arranged around the appointment. For diabetes, it links with the wider annual review (eyes, kidneys, feet and cardiovascular risk) and with dietitian, specialist nurse or podiatry input where needed.
Follow-up & long-term care
You will usually receive a clinic letter and a plan for follow-up, which may be a further appointment, a phone review, or discharge back to your GP with advice. Test results are reviewed at follow-up or communicated to you, and you should be told who to contact in the meantime.
- Attending agreed follow-up appointments or reviews
- Keeping up with monitoring blood tests for ongoing conditions
- Taking and reviewing any long-term medicines as advised
- For diabetes, keeping up annual checks of eyes, kidneys, feet and cardiovascular risk
- Reporting new or changing symptoms between appointments
Repeat, follow-on and what comes next
- A working diagnosis may be revised as test results come in.
- Treatment plans for hormone and diabetes conditions are often adjusted over time.
- Repeat assessment may be needed if symptoms change or results are borderline.
Ask what happens if the result is unclear or needs repeating, and what is included if further tests or follow-up are needed.
What good aftercare looks like
- A clear, shared plan and a clinic letter to you and your GP.
- A named contact route for results and questions.
- Sensible follow-up and monitoring for ongoing conditions.
- Honest discussion of uncertainty, with a safety net for new or worsening symptoms.
What affects the cost
Costs vary a great deal between people and providers, and we don't publish prices. What matters is understanding what drives the cost and making sure your quote is complete. The main things that affect it:
- Whether it is a first appointment or a follow-up, and the time allowed
- The seniority of the specialist seen
- Any tests arranged or done at the appointment
- Letters, reports or forms requested
- Number of follow-up appointments needed
- Whether dietitian, specialist nurse or other input is included
- The consultation fee and how long the appointment lasts
- Whether any tests are included or charged separately
- The cost of follow-up appointments
- Whether a clinic letter to you and your GP is included
- What happens, and what it costs, if further tests or scans are needed
- Who to contact about results and between appointments
On the NHS? Endocrinology and diabetes consultations are available on the NHS by GP referral; private appointments may offer quicker access or a second opinion but should still link with your GP and existing records.
You're entitled to your total cost in writing — including reports, follow-up and what happens if the result is inconclusive — before you decide.
Consent traps and marketing red flags
These are not small details. They are often where patients lose choice, time to reflect, or realistic expectations.
Consent traps
- Not being told that a first visit may not give a diagnosis.
- No clear explanation of what recommended tests will and will not show.
- Starting treatment without discussing alternatives and monitoring.
- No written summary or plan, leaving you unsure of the next steps.
Marketing red flags
- Promising a diagnosis or 'hormone optimisation' from a single private visit.
- Bundling extensive, unnecessary tests as a package.
- Starting hormone treatments without proper assessment, monitoring or GP involvement.
- Discouraging a second opinion or NHS involvement.
Choosing a specialist safely
- Check the specialist is on the GMC Specialist Register for this area.
- Make sure they work at a CQC-registered service, and look for membership of the relevant Royal College or professional body.
- You're entitled to time to consider and to have your questions answered before you agree — the specialist who looks after you should explain it, not a salesperson.
- Be wary of pressure: time-limited offers or deposits taken before you've had time to think are red flags, not bargains.
- You're entitled to your total cost in writing — including any follow-up — before you decide.
Questions to ask your medical professional
Take this to your consultation. A good specialist will welcome every one of these.
- What do you think is causing my symptoms or abnormal result?
- Which tests do you recommend, and what will they show or rule out?
- What are my treatment options, and what are the benefits and downsides of each?
- How will this be monitored, and how often will I be seen?
- What should I do, and who should I contact, if my symptoms change before then?
- Will my GP receive a letter, and can I have a copy?
- Are you on the GMC Specialist Register for this area, and which Royal College or professional body are you a member of?
- Will you be the specialist who carries out my appointment, and who looks after me afterwards?
- What are the risks for someone like me, and how often do your own patients have a problem or need it repeated or redone?
- What does a realistic result look like — and what can this appointment not achieve?
- What are my options, including waiting, doing nothing for now, or choosing a different approach?
- Can I have written information, results and aftercare instructions in a format I can use, including any accessibility or communication support I need?
- What is the total cost in writing, including any follow-ups, and how much time do I have to decide?
