What can a doctor do during a house call for a diabetes emergency?

A private physician measures blood glucose on the spot, performs a capillary ketone test when indicated, assesses consciousness and hydration, can give intravenous glucose or fluids and adjust insulin therapy. At signs of ketoacidosis or hyperosmolar hyperglycaemic state the physician arranges immediate transfer to a Munich hospital with a diabetology focus.

What does a private physician house call for diabetes cost in Munich?

Billing follows the GOÄ (German medical fee schedule for private medicine), from 180 € depending on time of day, day of the week and services rendered. Private health insurance and civil-servant aid usually reimburse in full; statutory (public) health insurance does not cover this private service.

Diabetes Emergencies — Hypo, Hyper, and When to See a Doctor

Q: When is hypoglycaemia life-threatening?

Hypoglycaemia becomes life-threatening when the person can no longer swallow, loses consciousness or has a seizure. Call 112 immediately and, if available, administer glucagon (nasal spray or intramuscular injection). Alert and cooperative patients with readings below 70 mg/dl (3.9 mmol/l) should immediately take 15–20 g of fast-acting carbohydrate (glucose tablets, fruit juice) and recheck after 15 minutes.

Q: How do I recognise severe hyperglycaemia?

Warning signs of hyperglycaemia are intense thirst, frequent urination, fatigue, blurred vision and nausea. Readings above 250 mg/dl (13.9 mmol/l) together with vomiting, abdominal pain, deep rapid breathing (Kussmaul respiration) or a fruity (acetone) odour on the breath raise suspicion of diabetic ketoacidosis — a life-threatening emergency that requires immediate hospital admission.

Q: What should I do first for hypoglycaemia?

Take 15–20 g of fast-acting carbohydrate — for example 4–5 glucose tablets, 100 ml of fruit juice or regular (non-diet) cola — then wait 15 minutes and recheck. If still below 70 mg/dl, repeat. Once stable, eat a slow carbohydrate (bread, banana) to prevent rebound. This is known internationally as the 15-15 rule.

Q: Which Munich hospitals specialise in diabetes emergencies?

LMU Klinikum (with the Diabetes Centre at the Innenstadt campus), Helmholtz Munich with its Institute for Diabetes Research, and Klinikum Schwabing have dedicated diabetology departments. For severe derailment, 112 ambulances will transport directly to the most appropriate hospital.

Reading time: 7 minutesEditorial: DoktorAkutUpdated April 2026

More than eight million people live with diabetes in Germany. Roughly half of them experience at least one blood-sugar derailment each year that goes beyond the routine. Munich, with its large senior population, significant tourist traffic, long walking distances around the Englischer Garten and Marienplatz, plus Oktoberfest and other festivals with irregular meals, sees a particularly high number of acute events.

Whether the diagnosis is type 1 or type 2 diabetes, both severe hypoglycaemia (low blood sugar) and severe hyperglycaemia with diabetic ketoacidosis or hyperosmolar hyperglycaemic state are medical emergencies. This guide will help you judge the situation correctly, take the right first steps, and choose the appropriate level of care.

Important: this text does not replace structured diabetes education or your regular appointments with a diabetologist or family doctor. It helps you interpret acute warning signs and decide when 112, a private physician house call, or scheduled outpatient care is the right choice.

Typical signs — telling hypo and hyper apart

Hypoglycaemia (blood glucose < 70 mg/dl / < 3.9 mmol/l)

Sudden onset — often within minutes
Shakiness, sweating, rapid heart rate, pallor
Intense hunger, trembling, headache
Difficulty concentrating, word-finding problems, irritability
Confusion, atypical behaviour, a "drunk" appearance
Severe form: loss of consciousness, seizures

Hyperglycaemia (blood glucose > 250 mg/dl / > 13.9 mmol/l)

Slow onset over hours to days
Intense thirst, frequent urination including at night (nocturia)
Fatigue, poor concentration, blurred vision
Dry skin, dry mucous membranes
In type 1 diabetes: nausea, vomiting, abdominal pain (suspect ketoacidosis)
Deep rapid breathing (Kussmaul respiration), fruity (acetone) odour on breath
In type 2 diabetes (rarer): hyperosmolar hyperglycaemic state with severe dehydration and altered consciousness

Call 112 immediately for:

Loss of consciousness or severe confusion
Seizure
Inability to swallow
Nausea and vomiting together with high blood glucose (suspected ketoacidosis)
Kussmaul breathing or acetone odour
Severe dehydration with circulatory compromise
Blood-sugar derailment in pregnancy or children

When should I call a doctor?

Call 112 immediately

Any hypoglycaemia with altered consciousness
Suspected ketoacidosis (abdominal pain, vomiting, acetone odour, Kussmaul breathing)
Hyperosmolar hyperglycaemic state (older type 2 patient, severe dehydration, altered consciousness)
Unexplained neurological symptoms in a known diabetic

Private physician house call is appropriate for

Recurrent mild hypoglycaemia without an obvious cause — therapy adjustment needed
Persistent elevated values (200–350 mg/dl) without signs of ketoacidosis
New diagnosis with unclear symptoms (initial assessment and counselling)
Intercurrent infection with glucose fluctuations in bed-bound patients
Follow-up visits after hospital discharge at home
Short-term assessment for travellers and tourists in Munich who have no diabetologist locally

Scheduled appointment with diabetologist / family doctor

HbA1c monitoring, annual kidney, eye and foot checks
Long-term therapy adjustment
Structured education, nutritional counselling

What a doctor can do during the house call

A private physician house call is a sensible step for stable blood-sugar derailment, recurrent hypoglycaemia or diabetology questions — especially when travel to a practice or hospital would be burdensome. The following services are possible at home:

Immediate capillary blood-glucose measurement
Assessment of consciousness, hydration status and breathing
Capillary ketone (β-hydroxybutyrate) test in selected situations
Measurement of blood pressure, pulse and oxygen saturation
Inspection of injection sites, insulin pump or continuous glucose sensor
Intravenous glucose for severe hypoglycaemia in a patient unable to eat or drink (G40, G20 dextrose solutions)
Fluid substitution (0.9 % saline) for mild dehydration
Structured conversation on insulin or oral therapy adjustment, individual dose recommendation
Private prescription for glucose tablets, glucagon emergency kit, test strips
Decision on hospital referral with pre-notification (for example LMU Klinikum, Klinikum Schwabing, Helmholtz)
Written report for your diabetologist and family doctor

What is not possible during a house call: HbA1c laboratory testing, C-peptide measurement, or insulin-pump reprogramming — for these, your diabetologist remains the right address.

Self-care before the visit

For hypoglycaemia (blood glucose < 70 mg/dl)

Take 15–20 g of fast-acting carbohydrate (4–5 glucose tablets, 100 ml fruit juice, 2 teaspoons of honey)
Wait 15 minutes, recheck — repeat if still low (the internationally recognised 15-15 rule)
After stabilisation, eat a slow-release carbohydrate (wholegrain bread, banana) to prevent rebound
Look for the cause: too much insulin, not enough food, unusual exercise, alcohol?
For altered consciousness: glucagon nasal spray or intramuscular injection by a trained family member — then call 112

For hyperglycaemia (blood glucose > 250 mg/dl)

Drink plenty of water or unsweetened tea (2–3 litres over several hours)
Type 1 diabetes: measure urine or blood ketones
Correction insulin according to your individual plan — when in doubt, contact your diabetologist
Physical rest — avoid exercise when glucose is high with ketones present
Check for triggers: infection, stress, missed insulin, high-carbohydrate meal, faulty pen or pump line
Moderate-to-high ketones with nausea: call 112

Why a house call — and why sometimes not?

Diabetes care in Munich is good but fragmented: family doctors, diabetologists, specialist practices (around Gärtnerplatz or in Bogenhausen), the Diabetes Centre at the LMU Innenstadt campus and outpatient clinics work in parallel but not always in a coordinated way. A house call closes a gap:

Stable derailment with a need for action: the doctor can adjust therapy at home without you waiting in a surgery.
Bed-bound or mobility-impaired patients: care homes rarely have a diabetologist on site — a house call is often the only practical option.
Tourists with diabetes: at Oktoberfest, in a hotel, or in a holiday apartment quick help is needed without being admitted to an unfamiliar hospital.
Children with diabetes: the familiar setting calms child and parents alike and reduces stress — an important factor for blood-sugar control.

A house call is not appropriate for life-threatening derailments (ketoacidosis, hyperosmolar state, severe altered consciousness). Every minute counts, and an ambulance to the TUM or LMU hospitals is the right choice. Video consultations can answer questions or give dose advice but cannot replace an examination — in altered consciousness or vomiting, physical assessment is indispensable.
