Online Diabetes Consultation — Ireland

About diabetes

Diabetes mellitus is a chronic metabolic condition characterised by raised blood glucose levels. Around 5–7% of adults in Ireland live with diabetes (HSE data), and prevalence is rising. The two main types — type 1 (autoimmune; insulin-dependent) and type 2 (insulin resistance + relative insulin deficiency; most common, often lifestyle-influenced) — have different causes but share long-term complications. Good control significantly reduces these risks.

Symptoms and signs

• Polydipsia — excessive thirst
• Polyuria — passing more urine, especially at night
• Unintended weight loss (especially type 1)
• Fatigue and lack of energy
• Blurred vision
• Slow-healing wounds, recurrent infections (thrush, UTIs)
• Tingling or numbness in feet (advanced)
• Often no symptoms in early type 2 — diagnosed on routine bloods

When to seek urgent care

An Online Doctor consultation is appropriate for: stable type 2 diabetes reviews, lifestyle support, prescription renewals, and follow-up. Seek emergency care immediately (999/112 or emergency department) for: drowsiness, confusion, or vomiting in someone known to have diabetes (could be DKA — diabetic ketoacidosis); severe hypoglycaemia (low blood sugar) unable to be managed at home; new-onset symptoms with unwell appearance (could be type 1 presentation); or severe foot infection. Type 1 diabetes is a medical emergency at presentation — anyone with the classic symptoms above should have same-day in-person assessment.

Diagnosis

Diagnosis per NICE and ICGP guidance is based on: HbA1c (glycated haemoglobin reflecting 3-month average glucose), fasting plasma glucose, or oral glucose tolerance test. HbA1c ≥48 mmol/mol on two separate occasions (or one with symptoms) confirms diabetes. Pre-diabetes (HbA1c 42–47) signals high risk and benefits from lifestyle intervention.

Treatment options — type 2 diabetes

Per NICE and ICGP guidance:

• Lifestyle modification — first-line. Weight loss (5–10% of body weight produces meaningful metabolic improvement), Mediterranean-style or low-carbohydrate dietary patterns, regular exercise (150 min/week moderate intensity), smoking cessation
• Metformin — first-line oral medication for most patients. Reduces hepatic glucose output and improves insulin sensitivity
• SGLT2 inhibitors (empagliflozin, dapagliflozin) — proven cardiovascular and renal benefits; first-line in patients with established cardiovascular or renal disease
• GLP-1 receptor agonists (semaglutide, liraglutide) — strong weight reduction and cardiovascular benefits; injectable
• Other oral agents — DPP-4 inhibitors, sulfonylureas, pioglitazone
• Insulin therapy — when oral and non-insulin injectables aren't sufficient, or in type 1 from diagnosis

Long-term care and screening

Per HSE National Diabetes Programme, all patients with diabetes should have:

• HbA1c every 3–6 months (target individualised, typically <53 mmol/mol)
• Annual blood pressure, lipid profile, kidney function (eGFR, urine albumin)
• Annual diabetic retinal screening (free under HSE Diabetic RetinaScreen for ages 12+)
• Annual foot review for neuropathy and circulation
• Cardiovascular risk assessment and management of BP, cholesterol, smoking
• Pneumococcal and annual flu vaccination

Self-care and lifestyle

Carb-conscious eating works for many: focus on vegetables, lean protein, healthy fats, and limit refined carbohydrates. Regular meals help glucose stability. Exercise after meals lowers post-meal glucose. Aim for 7+ hours of sleep — poor sleep worsens glucose control. Reduce alcohol. Daily foot inspection in advanced cases. Carry hypoglycaemia rescue (fast-acting glucose) if on insulin or sulfonylureas. Connect with Diabetes Ireland for support and education.

Frequently asked questions

Can I get my diabetes medication renewed online?

Yes — for clinically stable patients on routine type 2 diabetes medication where HbA1c, BP, and complications screening are current. The Online Doctor will check your last review, current control, and recent symptoms. If reviews are overdue or control is suboptimal, an in-person review with your treating doctor is appropriate.

Should I be on an SGLT2 or GLP-1?

These medications have transformed type 2 diabetes care because of their cardiovascular and weight-related benefits beyond glucose lowering. Eligibility depends on individual factors (cardiovascular risk, renal function, BMI, preferences). Discuss with your Online Doctor or treating doctor.

Can type 2 diabetes be reversed?

Yes — significant weight loss (often 10–15 kg+) in earlier-stage type 2 diabetes can achieve "remission" (normal glucose without medication) in a meaningful proportion of patients per UK DiRECT trial evidence. This is a structured, supervised intervention — discuss with your doctor.

What's the difference between type 1 and type 2?

Type 1 is autoimmune destruction of pancreatic insulin-producing cells — usually diagnosed in childhood or young adulthood, lifelong insulin treatment required. Type 2 involves insulin resistance and relative insulin deficiency — more common with age and obesity, often manageable with lifestyle and oral medications initially.
