Endocrinology in Germany means finding the cause of a hormonal disorder and treating it at university and specialist hospitals, on a plan drawn up in advance from the patient’s results. Hormonal disorders rarely announce themselves plainly. Tiredness, weight gained or lost, mood swings, trouble with the heart or the skin — a person goes from one specialist to another for a long time before it emerges that the cause lies in the endocrine system. By the time treatment abroad comes up, a pile of test results has usually accumulated and there is still no clarity.
German endocrinology begins by providing that clarity: first establishing which gland is not working properly and why, and only then choosing a treatment. This page covers diagnosis, the main areas, treatment, the hospitals and how a trip is arranged.
What Endocrinologists Treat and Why Patients Come to Germany
Endocrinologists treat disorders of the hormone-producing glands and the metabolic problems that depend on them. Endocrinology in Germany covers the thyroid and the parathyroids, tiny glands beside it that control calcium; the pancreas, whose insulin is central to diabetes; the adrenal glands; the pituitary, a small gland at the base of the brain that directs many others; the sex hormones; and metabolism and bone, including osteoporosis.
The endocrine system governs the body through hormones, and a fault in one gland is felt everywhere at once. So precise measurement matters, and so does a doctor who reads results in combination rather than one by one: thyroid hormones, for example, are interpreted together with TSH, the pituitary hormone that controls the thyroid.
Diabetes shows the scale. According to the German Health Report on Diabetes 2026 from the German Diabetes Society and diabetesDE, about 9.3 million people in Germany live with type 2 diabetes, and around 450,000 new cases are added every year. Complex cases are habitually reviewed jointly: endocrinologist, surgeon and, where needed, oncologist.
Diagnosis: Blood Tests, Imaging and Function Tests
In endocrinology a diagnosis rests on measurements: blood tests for sugar and for particular hormones show which gland is working in excess and which in deficit. Timing matters. Cortisol is much higher in the morning than in the evening, and sugar and several hormones are measured fasting, so samples are taken at set times and judged against the testing laboratory’s reference range. Which hormones are tested, and in what order, is covered on the page on hormone tests in Germany.
When one blood test is not enough, the gland is challenged in a function test: the patient receives a substance that should raise or suppress a hormone, and the response of the gland is measured. If excess cortisol is suspected, for instance, the patient takes a dexamethasone tablet; normally cortisol then falls, and if it does not, the doctors look for the source. Some tests take several hours at the hospital with repeated blood samples.
When the gland itself has to be seen, imaging is used: thyroid ultrasound, CT or MRI of the adrenals, MRI of the pituitary and, where needed, scintigraphy, a scan with a small dose of radioactive tracer showing which parts of the thyroid are most active. A fine-needle biopsy of a thyroid nodule takes a tiny tissue sample to tell a harmless nodule from one that needs treating. The investigations are matched to the case; nothing superfluous is ordered.
Main Areas: Thyroid, Diabetes, Adrenals and Pituitary
The main areas of endocrinology are the thyroid, diabetes, the adrenals and pituitary, and hormone replacement. The thyroid can be underactive or overactive, develop nodules, or be gradually damaged by the immune system in autoimmune (Hashimoto’s) thyroiditis; how each of these is investigated and managed is described on the page on thyroid disease treatment. Thyroid cancer belongs to oncology and is treated by oncologists.
In type 1 diabetes the body almost stops producing insulin; in type 2 insulin is present but works less well. A diabetes specialist adjusts the therapy, fits an insulin pump and a continuous glucose sensor where needed and teaches the patient to manage the condition; more on the page on diabetes treatment in Germany. Stem cell treatment for diabetes is still at the clinical trial stage, not routine care.
Adrenal and pituitary conditions are rarer and often go unrecognised for years. A small benign tumour in one of these glands can produce excess hormone: aldosterone, and blood pressure barely responds to tablets; cortisol, and weight, skin, blood pressure and blood sugar change; growth hormone, and the face, hands and feet slowly enlarge. Insufficiency, when a gland makes too little hormone, causes weakness, low blood pressure and weight loss.
A separate area is replacing hormones the body no longer makes in sufficient amounts: oestrogen in the menopause, when hot flushes and sleeplessness disrupt daily life; testosterone in men with a confirmed deficiency; adrenal and pituitary hormones when those glands fail. Who is suited to this and how its risks are weighed is explained on the page on hormone replacement therapy.
Treatment: Medication, Surgery and a Second Opinion
Endocrine conditions are treated mainly with medicines that replace a missing hormone or reduce an excess one; surgery is needed less often, and where the diagnosis is in doubt, a second opinion comes first. An underactive thyroid, for example, is treated by supplying the missing hormone; with too much hormone, production is reduced with medication or, sometimes, the source is removed surgically. Many endocrine conditions are not “cured during a trip”: they are brought under control and managed for years. Treatment follows the guidelines of German medical societies in the AWMF register, such as the one on radioiodine therapy for benign thyroid disease.
For an overactive thyroid there is also radioiodine therapy: the patient swallows a capsule of radioactive iodine (sometimes a liquid), which collects mainly in the thyroid, so the radiation acts on the gland from within. In Germany it is given on a nuclear medicine ward as an inpatient, until the radioactivity in the body has fallen to a permitted level. Surgery is used where medication does not solve the problem, for some nodules and tumours of the thyroid, adrenals or pituitary, often minimally invasively, through small incisions and under magnification, but on indication, not “just in case”.
If a diagnosis has been made at home but doubts remain, start with a second opinion: a German endocrinologist reviews your results, scans and reports and says whether they agree with the diagnosis and the approach. Sometimes that changes the therapy; sometimes it spares an unnecessary operation. How to arrange this is covered on the page on a second opinion in Germany.
Where Endocrine Conditions Are Treated in Germany
In Germany endocrine conditions are treated in university endocrinology departments, specialist diabetes centres and endocrine surgery units; the full directory is on the page on endocrinology hospitals in Germany. University Hospital Düsseldorf has a Department of Endocrinology and Diabetology, and University Hospital Essen a Department of Endocrinology, Diabetology and Metabolism. At University Hospital Dresden, endocrinology and diabetes are part of Medical Clinic III, directed by Prof. Stefan R. Bornstein; its metabolic vascular medicine division is headed by Prof. Nikolaos Perakakis.
Other centres focus on diabetes and metabolism. At m&i Specialty Clinic Bad Heilbrunn, the Centre for Diabetes and Metabolic Diseases is led by chief physician Dr Andreas Liebl; the Heart and Diabetes Center NRW in Bad Oeynhausen combines cardiology with a department of diabetology and endocrinology. Children and adolescents with diabetes are treated, for example, at the children’s diabetes centre of DRK Kliniken Berlin Westend, headed by Dr Silvia Müther.
Operations on the thyroid and other glands are performed by endocrine surgeons; at the Israelite Hospital Hamburg, Dr Lena Eckert-Schrage heads the endocrine surgery section. In Munich, adults are seen at the Department of Endocrinology and Diabetology of Munich Hospital Schwabing, while the children’s clinic at Munich Hospital Harlaching looks after children with diabetes. A hospital is chosen by diagnosis and the scope of care needed, not by a famous name.
Frequently asked questions
When is it worth seeing an endocrinologist in Germany?
It is worth it when an accurate diagnosis cannot be made at home or treatment is not working: contradictory results, blood pressure or blood sugar that will not settle despite medication changes, a tumour in an adrenal gland or the pituitary, or a proposed thyroid operation you want to be sure about. If you only need existing results interpreted, a second opinion based on documents may be enough.
How long does an assessment by an endocrinologist take?
It depends on the question. Blood tests and a thyroid ultrasound are usually done as an outpatient. Function tests, an MRI of the pituitary, a CT of the adrenals or a surgical consultation take longer, and some tests need preparation in advance. The hospital sends an outline plan with its cost estimate, so you know the length of the stay before you travel.
What should I do about my medicines before seeing an endocrinologist?
Do not stop anything on your own: hormones and other medicines should be changed or paused only on a doctor’s instructions. Some drugs do distort results, though: certain blood pressure medicines affect the aldosterone test, and high-dose biotin, taken for hair and nails, can skew thyroid hormone tests. So send the full list of medicines and supplements with doses in advance; any change is agreed before the trip.
How much does an endocrinology assessment in Germany cost?
There is no single price: the cost depends on the tests, whether MRI, CT or scintigraphy is needed, whether the assessment is outpatient or inpatient, and whether an operation follows. The hospital states the exact amount in its cost estimate once it has reviewed your documents, so the first step is to send recent results and reports.
How AlenMed Arranges Endocrinology Treatment in Germany
Arranging endocrinology treatment in Germany starts with documents: test results with dates and the laboratory’s reference ranges, ultrasound, CT and MRI reports, and a list of all medicines with doses. We have them translated into German and sent to a suitable department; the hospital replies with an assessment plan and a cost estimate (Kostenvoranschlag), and payment goes directly to the hospital.
Timing is agreed before the trip, because some tests require preparation and a temporary pause in medication. We help with the visa invitation, an interpreter and accommodation. The company’s office is in Munich, and its 86 partner hospitals are in 38 cities across Germany. After you return home, follow-up can continue by video.
This material is for information only and is not an offer. Treatment is decided by a doctor at an in-person consultation, and the final cost by the hospital’s estimate.
