5 hospitals provide care in this specialty across 2 countries through the Voumed network; 2 of them hold JCI accreditation.
Internal medicine is the specialty of adult medicine that diagnoses and treats diseases of the internal organs without surgery, and it is often the right starting point when symptoms are vague, overlapping or hard to place. An internist looks at the whole person rather than one organ, so the field suits adults living with several long-term conditions, people with unexplained complaints such as weight loss, fever or fatigue, and anyone who needs a medical review before an operation. International patients travel for it to reach an unhurried, thorough assessment in which tests are arranged within a few days and read together, to obtain a second opinion on a puzzling diagnosis, or to have a complex list of medicines reviewed and simplified by one team.
Key takeaways
- Internal medicine covers the non-surgical diagnosis and long-term care of adult diseases, from high blood pressure and diabetes to anaemia, infections and problems that involve several organs at the same time.
- An internist is often the right first doctor when symptoms are vague or overlapping, because the job is to find the cause and then involve the correct organ specialist.
- Most of the work is outpatient: a detailed history, an examination, blood tests and imaging, gathered over a few days and interpreted together rather than one result at a time.
- Before planned surgery abroad, an internal medicine review checks the heart, lungs, kidneys, blood sugar and medicines so that risks are found and managed before the day of the operation.
- Because many conditions here are long-term, a visit should end with a written plan, an updated medication list and clear targets that a doctor near your home can continue.

Overview
Internal medicine, sometimes called general medicine, is the branch of medicine devoted to adults and to the diseases of the internal organs: the heart and blood vessels, lungs, digestive tract, liver, kidneys, blood, glands and immune system. Internists are trained to handle complexity. Many adults live with more than one condition at once, such as high blood pressure, diabetes and kidney disease, and each treatment can affect the others. The internist keeps the whole picture in view, decides which problems need attention first and makes sure medicines work together rather than against each other. The specialty is also the home of diagnostic reasoning: when someone has symptoms that do not point clearly to one organ, the internist works through the possibilities in a structured way and brings in the relevant organ specialist once the direction is clear. In hospitals, internists also look after medical inpatients and advise surgical teams.
Conditions and sub-specialties
The everyday work of internal medicine covers the common long-term conditions of adult life: high blood pressure, type 2 diabetes, raised cholesterol, obesity, thyroid imbalance, anaemia, fatty liver, chronic kidney disease and the gradual changes of ageing. It also covers acute medical illness, such as pneumonia, urinary and other infections, dehydration and flare-ups of chronic disease. A large and important part is the unexplained problem: weight loss without trying, persistent fever, night sweats, long-lasting tiredness, swollen lymph nodes or abnormal blood tests found by chance. Within the specialty, general internal medicine handles this broad range, geriatric medicine focuses on older adults living with frailty and many medicines, and perioperative medicine prepares people for surgery and supports their recovery. When the picture narrows to one organ, care moves to the matching specialty, such as cardiology, gastroenterology, nephrology or endocrinology.
Common treatments and procedures
Treatment in internal medicine is mainly medical: choosing, adjusting and combining medicines, together with advice on diet, activity, sleep, alcohol and smoking. For high blood pressure, diabetes and cholesterol this means setting clear targets and a plan to reach them. For people taking many medicines, a structured review can stop drugs that are no longer needed, remove harmful combinations and simplify doses, which often helps people feel better and safer. For an unexplained illness, the main treatment at first is the diagnostic work-up itself, followed by referral to the right specialist once a cause is found. Before surgery, the internist assesses fitness for anaesthesia and the operation, adjusts blood thinners and diabetes medicines, and plans how chronic conditions will be managed around the procedure. Vaccinations, screening advice and lifestyle counselling are part of the same visit, so prevention runs alongside treatment.
Diagnostics and technology
The internist's main tools are a careful history and a full physical examination, and much of the diagnostic value comes from deciding which tests are actually needed. Blood tests measure blood counts, kidney and liver function, blood sugar and HbA1c, cholesterol, thyroid hormones, inflammation markers and vitamin levels, while a urine test adds information on the kidneys and on infection. An electrocardiogram records the heart rhythm, and a chest X-ray, abdominal ultrasound and echocardiography give a quick view of the lungs, abdominal organs and heart. When a question needs more detail, CT or MRI scans, a 24-hour blood pressure or heart rhythm recording, or an endoscopy are arranged with the relevant team. The aim is a focused set of investigations that answers the clinical question, rather than a long list of tests that can create false alarms and further anxiety.
What to expect as an international patient
For travelling patients, the most useful preparation is to send your records in advance: previous test results, scan reports, discharge letters and a complete list of your medicines with doses, including supplements. A remote review lets the team plan the first visit and book the right tests, including any that need fasting. Most internal medicine assessments are outpatient and can be completed in two to five days, with a long first consultation, tests over the following days and a final meeting to discuss the results. A short hospital admission is needed only when an illness requires closer monitoring or treatment through a drip. If you are travelling for surgery, an internal medicine review is often booked a day or two before the operation. Interpreter and international patient support is commonly available, and you should leave with a written summary and medication plan for your doctor at home.
Frequently asked questions
These answers are general guidance and may vary by provider. Confirm the details with the hospital you choose.
What is the difference between an internist and a general practitioner?
A general practitioner or family doctor looks after people of all ages and handles a wide range of everyday problems in the community. An internist is a specialist in adult medicine with longer hospital-based training in complex and multi-organ disease. Internists are often consulted when a problem is hard to diagnose, when several conditions interact, or when a patient needs hospital-level investigation.
When should I see an internist rather than an organ specialist?
See an internist when your symptoms do not clearly belong to one organ, when you have several long-term conditions that affect one another, or when test results are abnormal without an obvious cause. If the problem is already known and limited to one organ, such as a heart rhythm disorder or a kidney condition, going directly to that specialty is usually more efficient.
Can internal medicine give me a second opinion?
Yes. A second opinion is a common reason to see an internist, particularly when a diagnosis is uncertain or treatment is not working as expected. The team reviews your records, scans and medicines, examines you and may repeat or add tests. You then receive a written opinion that you can share with your doctors at home, who stay in charge of your ongoing care.
How many days should I plan for an internal medicine assessment?
Most assessments are completed in two to five days. The first consultation usually takes longer than a routine appointment, tests are booked over the following days, and a final meeting brings the results together. If a scan or an endoscopy is needed, or a referral to another specialist is made, plan an extra day or two.
Do I need to fast before my visit?
Some blood tests, such as fasting blood sugar and cholesterol, are most accurate after about 8 to 12 hours without food, while drinking water is normally allowed. An abdominal ultrasound also usually needs a few hours of fasting. Your coordinator will tell you in advance which tests are planned, whether you need to fast and whether to take your usual medicines that morning.
Why is a medical review advised before surgery abroad?
Surgery and anaesthesia place extra strain on the heart, lungs and kidneys, and long-term conditions or certain medicines can raise the risk of complications. A pre-operative review checks these, adjusts blood thinners and diabetes medicines, and confirms that conditions such as high blood pressure are under control. Finding a problem before travel or before the day of the operation avoids last-minute cancellations.
Will there be interpreter and language support?
Yes. International patient services commonly include interpreters and coordinators who help with appointments, consent, preparation instructions and everyday questions. Because internal medicine relies so much on a detailed history, it helps to write down your symptoms and medical background in advance, so that nothing important is lost in translation.
How does follow-up work once I am home?
You receive a written summary with your diagnoses, test results, medicines and doses, and the targets to aim for, such as blood pressure or blood sugar ranges. Routine blood tests and adjustments are usually done by a doctor near your home, and the team can often stay reachable by message or video to review new results and answer questions.
