Online GP for Chronic Disease Follow-Up: Hypertension, Diabetes and Asthma Reviews

Geoff keeps his blood pressure readings in a brown envelope on the kitchen counter of his flat near Alicante. Sixty-odd entries in biro, written twice a day since March, along with the boxes of three medicines he has taken for eleven years. He retired from Bristol four years ago. His English surgery removed him from their list once he stopped being resident, his Spanish registration is partly complete but his conversational Spanish runs out somewhere around the word for kidney, and the last person to look at that envelope was his daughter, who works in logistics. He is not ill. He is unreviewed, which over a decade is its own kind of risk.

Chronic conditions are managed in intervals — the six-month check, the annual review, the medication renewal — and those intervals are where care most often falls through the cracks, particularly for people who move between countries, work irregular hours, care for someone else, or live an hour from the nearest clinic. Interest in an online GP for chronic disease follow-up comes from exactly that reality. The honest position is that remote review does some parts of chronic care as well as or better than a clinic room, and cannot do other parts at all. Knowing which is which is what makes the hybrid approach work.

What a chronic disease review is actually for

A good review is not a ritual. It asks a small number of consequential questions. Is the condition controlled by the measures that matter? Is the person actually taking the treatment, and if not, why not? Are there side effects that have quietly changed their life? Have complications begun to appear? Do the monitoring tests need repeating, and are they overdue? Does anything need to change before the next interval?

Notice how much of that is conversation and data review rather than physical examination. In hypertension, diabetes and asthma, the most informative material is often generated at home over weeks — readings, logs, symptom patterns, inhaler use — and interpreted in a discussion. That is why these three conditions are the strongest candidates for remote follow-up, and also why a remote review that skips the necessary laboratory work is incomplete rather than clever.

Hypertension: home readings are often the better evidence

A single clinic blood pressure reading is a poor sample. It captures one moment, frequently a stressful one, and white-coat elevation is common enough that European guidance places substantial weight on out-of-office measurement, whether by home monitoring or twenty-four-hour ambulatory monitoring. Masked hypertension — normal in clinic, high at home — is the mirror problem and is arguably more dangerous because it goes unnoticed.

A properly conducted home series is genuinely useful clinical data, and it is one of the reasons a video review can be substantive rather than superficial. Doing it correctly matters more than doing it often:

• Use a validated upper-arm monitor with the correct cuff size for your arm. Wrist and finger devices are less reliable.
• Sit with your back supported, feet flat on the floor, legs uncrossed, and your arm resting on a table at roughly heart height.
• Rest quietly for five minutes first. No talking, no phone, no television.
• Avoid caffeine, smoking, exercise and a full bladder in the half hour beforehand.
• Take two readings a minute apart, morning and evening, and record all of them including the ones you dislike.
• Do this for seven consecutive days, then discard the first day and average the rest. That average is the number that means something; individual spikes usually do not.
• Note the time, and whether it was before or after your tablets.
• If your monitor gives an irregular heartbeat symbol repeatedly, mention it — that finding matters.

A remote review can interpret that series, discuss lifestyle factors with the time to do it properly, check for side effects such as ankle swelling, cough, dizziness on standing or cramps, review interactions with anti-inflammatories or decongestants, and reinforce why treatment continues when someone feels perfectly well. What it cannot do is take the blood tests that safe blood pressure management depends on. Kidney function and electrolytes need checking when certain medicines are started or adjusted, and cholesterol, glucose and other cardiovascular risk markers form part of periodic review. An ECG, examination of the heart and chest, and eye examination for hypertensive changes are all in-person tasks. A very high reading with symptoms, or any suspicion of hypertensive emergency, is not a remote matter at all.

Type 2 diabetes: logs, patterns and the tests that cannot be skipped

Diabetes review is the clearest example of a split task. A large part of it is reading data and having a frank conversation; another part requires a laboratory, a pair of hands and a retinal camera.

What remote review does well: interpreting a glucose logbook or downloaded meter or continuous monitor data, spotting patterns such as consistent early-morning highs or post-meal spikes or overnight lows, discussing hypoglycaemia awareness and how it is being managed, reviewing injection or inhaler technique on camera, going through diet and activity with more time than a rushed appointment allows, checking for symptoms suggesting complications — numb or burning feet, visual changes, erectile dysfunction, unexplained weight loss, recurrent thrush or infections — reviewing sick-day rules, discussing driving obligations, and having an honest conversation about adherence.

What must happen in person: HbA1c and other blood tests, urine albumin-to-creatinine ratio, blood pressure measured on a validated device, a proper annual foot examination assessing sensation, pulses, skin and nails, retinal screening photography, and weight and waist measurement on reliable scales. Any new foot ulcer, spreading redness, or a hot swollen foot in someone with diabetes is an urgent in-person problem, not a review topic.

Medication decisions in diabetes frequently depend on kidney function and recent HbA1c, which is why a responsible remote clinician will often say that a dose change needs current bloods first. That is not obstruction; it is the correct sequence. Our licensed and registered doctors work this way, and our broader range of consultation and prescription renewal services is built around that hybrid pattern rather than pretending everything can be done on screen.

Asthma and COPD: the review where video adds something in-person visits often miss

Inhaler technique is the clearest example of remote care doing a job well. A large proportion of people using inhalers use them imperfectly — not shaking a device, not exhaling first, actuating at the wrong moment, not holding breath afterwards, using a spacer incorrectly, or failing to rinse the mouth after a steroid inhaler. A video call lets a clinician watch you use your own device, in your own home, with your own spacer, and correct what they see. Patients often report having never been asked to demonstrate it in a clinic.

Remote asthma review also handles symptom scoring well — how many nights disturbed, how often the reliever is used, whether exercise is limited, how many courses of steroids or exacerbations in the past year — along with peak flow diary interpretation, trigger identification, written action plan review, smoking and vaping discussion, and adherence to preventer treatment, which is the recurring reason control slips. Increasing reliever use is one of the most important signals in respiratory medicine and is picked up by conversation, not by examination.

What needs in-person work: spirometry and reversibility testing, FeNO where available, chest examination, oxygen saturation measured properly, chest imaging, blood tests, allergy testing, and vaccination. Diagnosis of asthma or COPD should not be made purely remotely, because it depends on objective lung function measurement. An acute exacerbation with breathlessness at rest is an emergency or urgent in-person matter.

What a remote review can and cannot cover, condition by condition

Condition	Handled well by video review	Requires in-person or laboratory
Hypertension	Seven-day home reading averages, technique check, side effect review, adherence, lifestyle, interaction check with painkillers and decongestants	Kidney function and electrolytes, lipids, ECG, heart and chest examination, eye examination, ambulatory monitoring, suspected hypertensive emergency
Type 2 diabetes	Glucose or sensor data interpretation, hypoglycaemia review, injection technique, diet and activity discussion, sick-day rules, complication symptom screening	HbA1c, kidney function, urine albumin-to-creatinine ratio, annual foot examination, retinal screening, measured weight and blood pressure
Asthma	Inhaler and spacer technique on camera, symptom and reliever-use scoring, peak flow diary, trigger and action plan review, adherence	Spirometry with reversibility, FeNO, chest examination, oxygen saturation, allergy testing, acute exacerbation care
COPD	Breathlessness scoring, exacerbation history, inhaler technique, rescue pack use review, smoking cessation support, pulmonary rehabilitation referral discussion	Spirometry, chest examination and imaging, oxygen assessment, blood tests, vaccination
Raised cholesterol and cardiovascular risk	Adherence, muscle symptoms and side effect review, diet and activity, risk discussion	Lipid profile, liver function, blood pressure measurement, glucose or HbA1c
Hypothyroidism	Symptom review, adherence, timing of the dose relative to food and other tablets	Thyroid function blood tests, which drive any dose change
All of the above	Medication reconciliation, deprescribing discussion, safety-netting plan, documentation for work or insurance where supported	Anything requiring hands, needles, imaging or machines; controlled medicines; emergency care

Adherence and polypharmacy: the conversation nobody has time for

Ask a busy clinic whether a patient takes their tablets and the answer is usually yes. Ask with fifteen unpressured minutes and a different picture emerges: the tablet skipped on work days because of the diuretic effect, the statin stopped six months ago after reading something online, the inhaler used only when symptoms appear, the blood pressure medicine halved independently because of dizziness, the medicine that ran out in another country and was never restarted. None of this is unusual and none of it is a moral failing. All of it changes the interpretation of a set of readings.

Remote appointments seem to encourage that honesty, partly because people are on their own territory and partly because a video appointment tends to feel less rushed than a clinic slot. A useful review therefore starts with the medicines physically in front of you — actual boxes, not a remembered list — and works through what is being taken, what is not, and what is left over. Bring everything, including supplements, herbal products and anything bought over the counter, because interactions with ordinary purchases such as anti-inflammatories or decongestants are among the commonest avoidable problems in chronic disease.

Two short scenarios

The following scenarios are illustrative, not accounts of real patients.

Geoff, 68, Alicante. The brown envelope turns out to be valuable. Averaged properly after discarding the first day, his readings are consistently above target in the mornings and acceptable in the evenings, and he has been taking all three tablets at bedtime because that is what he was told in 2013. He also mentions ankle swelling he had assumed was the heat. The consultation produces three things: a plan for repeat kidney function and electrolyte testing locally before any change is made, a discussion of dose timing that will be decided once those results are back, and a referral note in both English and Spanish that he can hand to a local clinic. He does not get a medication change on the call, because doing that without current bloods would be poor practice. He gets a route out of eleven years of drift. Details of how we handle this kind of cross-border coordination are on our about page.

Valentina, 44, Naples, asthma since childhood. She books a review because her preventer prescription lapsed. On camera she demonstrates her inhaler and takes a fast, sharp breath from a device that needs a slow steady one, then holds nothing afterwards. She has used three reliever canisters since February and wakes coughing perhaps twice a week. The technique is corrected live, with a spacer recommended and demonstrated. Her reliever use and night symptoms indicate her control is not good, so the review also arranges in-person lung function testing rather than treating a fixed prescription renewal as the whole task. Two months later she is using her reliever occasionally rather than daily, and the difference came from something no telephone call and few clinic appointments would have caught.

Red flags: when a review is the wrong response

Chronic conditions produce acute emergencies, and a scheduled appointment is not the right tool for any of them.

• Cardiovascular: chest pain or pressure, pain radiating to arm, jaw or back, sweating with nausea, sudden severe breathlessness, fainting, palpitations with collapse. Also sudden weakness or numbness on one side, facial droop, slurred speech or sudden visual loss — stroke symptoms are time-critical.
• Diabetes: vomiting with high glucose, deep rapid breathing, fruity-smelling breath, drowsiness or confusion — possible ketoacidosis. Also severe hypoglycaemia with confusion, seizure or inability to swallow, and any new foot ulcer, blackening, or a hot swollen red foot.
• Asthma and COPD: breathlessness at rest, inability to complete a sentence, reliever not working or not lasting, blue or grey lips, exhaustion with breathing, or a silent chest.
• Hypertension: very high readings with chest pain, severe headache with visual disturbance, neurological symptoms, breathlessness or confusion.

Emergency numbers: 112 throughout the European Union, including Spain, Italy and Germany; 999 in the United Kingdom; 15 for SAMU in France; 118 for the Italian medical emergency line; and 116117 in Germany for problems that need a doctor today but are not emergencies. For chest pain or stroke symptoms, call rather than drive, and do not wait to see whether it settles.

The hybrid model, described plainly

The realistic shape of remote chronic care is a partnership rather than a replacement. Your national system — the Spanish SNS, French Assurance Maladie, the NHS, the Italian SSN, or a German statutory insurer — remains where blood tests, retinal screening, spirometry, foot checks, vaccinations and specialist referrals happen, and those services are structured around exactly this kind of monitoring. Remote consultations add capacity at the points where systems are slowest: interpreting the data you have collected, reviewing technique and adherence, catching interactions, preparing you for a productive local appointment, and reviewing results once they exist.

Practically, that means a remote review is most valuable when you arrive with material. Recent test results, if you have them. A seven-day blood pressure series rather than one alarming reading. A glucose log or a sensor download. A peak flow diary. The actual medicine boxes. A list of your questions in order of importance, because the third question is often the one that matters most and the one that gets lost. Booking through Online Doctor Consultation lets you choose the exact slot, so you can sit down with your paperwork already spread out and know the doctor will join at that time rather than at some unpredictable point in the afternoon.

Honest limitations

A video consultation cannot listen to your heart or chest, cannot palpate an abdomen, cannot examine feet for neuropathy or pulses, cannot look at your retinas, cannot take blood, cannot perform spirometry or an ECG, cannot measure your blood pressure or oxygen level with its own validated equipment, cannot administer vaccines, and cannot provide emergency care. It cannot prescribe controlled medicines. It cannot issue every nationally specific certificate, since some forms legally require a locally registered practitioner. It also cannot take over the statutory disease-register functions that national primary care systems perform.

There are situations where remote follow-up is inappropriate as a model rather than merely limited: newly suspected diagnoses that need objective testing, unstable or rapidly deteriorating disease, complex multi-morbidity with frailty, significant cognitive impairment without a supporting carer, and anyone whose last relevant blood test is long overdue. A clinician who tells you that is doing their job. Our frequently asked questions set out which documents and reviews are possible in each of our markets, and unusual cross-border situations are worth raising through our contact page before you book.

Health records generated in consultations are processed under the GDPR, which gives you rights of access and portability — useful in practice, because a written consultation summary is something you can hand to a local doctor. Where your question is really about a country we do not serve clinically, the Online Doctor Consultation network is a reasonable starting point, alongside European resource pages and Spanish-language material. Treat all three as reference material. They are separate network sites rather than the same clinical service.

Frequently asked questions

Can an online GP renew my long-term medication?

Often yes, where the condition is stable, the history is clear and required monitoring is up to date. A clinician may issue a shorter supply and ask for current blood tests before continuing, particularly for medicines whose safety depends on kidney function, liver function or thyroid results. Renewal is a clinical decision rather than an administrative one.

How many blood pressure readings should I bring to a review?

Ideally two readings morning and evening for seven consecutive days, with the first day discarded and the rest averaged. That average is far more informative than a single reading, and bringing the raw numbers rather than only the average lets the doctor see the pattern and the variability.

Can my diabetes review be done entirely online?

No. Substantial parts can — data interpretation, technique, adherence, symptom review, diet and activity — but HbA1c, kidney function, urine testing, annual foot examination and retinal screening all require in-person services. A remote review works best alongside those, not instead of them.

I have moved country and lost touch with my old surgery. Where do I start?

Register with the local system as soon as you can, since that is where monitoring tests and screening will happen. In the meantime a remote consultation can review your current treatment, produce a written summary and medication list you can hand over locally, and identify which tests are overdue so your first local appointment is productive rather than exploratory.

Can a doctor check my inhaler technique over video?

Yes, and this is one of the areas where remote review performs particularly well. You use your own device and spacer while the clinician watches, and errors that are common and consequential can be corrected on the spot. Have every inhaler and spacer with you at the start of the appointment.

Will an online review change my medication doses?

Sometimes, if the necessary information is available and the change is safe. Frequently the honest answer is that a change requires current blood tests or objective measurements first. Any adjustment is a clinician's decision based on assessment, and no service can promise a particular dose or medicine in advance.

Does a private online review replace my annual check with my public system?

It does not. National systems run structured chronic disease monitoring, screening and vaccination programmes that should continue. Remote private reviews are best used to fill gaps in timing, to prepare for and follow up on local appointments, and to get unhurried time discussing data and adherence. Our health library covers home monitoring in more detail.

What does a chronic disease review consultation cost?

Consultations start from €39 for a standard consultation, with sick notes and prescription renewals from €35. Blood tests, spirometry, retinal screening and other investigations are arranged and charged locally, and medicines are paid for separately at the pharmacy.

Chronic conditions require individualised management, and decisions about medicines and monitoring must be made by a clinician who has assessed you and has access to your current results. Booking a consultation does not guarantee any medication, dose change or specific outcome.

Making your next review count

Chronic conditions reward preparation more than urgency. Before your next appointment, whether local or remote, spend a week collecting proper home readings, gather your most recent test results, put every medicine box on the table including the ones you have stopped, and write down your questions with the most important first. Then use the appointment for judgement rather than data entry: what the numbers mean, whether the treatment still fits your life, which tests are overdue, and what should happen if things change before the next review. If a scheduled remote slot with unhurried time is what makes that possible, it is a reasonable place to start — provided the plan it produces sends you for the tests only a local service can do.
