A health checkup refers to various examinations aimed at the early detection of diseases. In Germany, public health insurance plans cover the cost of this examination every three years for all insured individuals aged 35 and older. The examination is also known as the “Check-up 35.” Read more here about the procedure and the goals of the check-up, and find doctors who perform the check-up.

Article Overview

What is a checkup?

A health check-up is designed to detect common diseases at an early stage so that

  • can be effectively treated and
  • can be detected in their early stages through diagnostic measures.

These include

The incidence of these diseases increases starting at around age 35. For this reason, health insurance plans cover the cost of a basic check-up for everyone aged 35 and older every three years.

The health check-up is performed by primary care physicians (general practitioners, family physicians, and internists).

The health checkup consists of various components:

  • a medical history review,
  • a physical examination, including a blood pressure measurement,
  • a urine test for blood, protein, and glucose (sugar), and
  • a blood test to measure cholesterol and glucose levels.

After the test results have been evaluated, a follow-up consultation takes place. During this consultation, the doctor informs the patient of the findings. If necessary, the doctor may also recommend further tests.

Purpose of the Health Checkup

The health check-up aims to identify diseases that often do not cause any physical symptoms in their early stages. Therefore, even people who feel fit and physically healthy should undergo a health check-up.

Only through regular checkups can changes in the body be detected early and health risks averted. This allows suspected cases to be diagnosed more thoroughly through follow-up tests and identified conditions to be treated in a timely manner. This increases the chances of recovery.

In addition, unhealthy behaviors can be identified and modified through a check-up.

There are known risk factors for cardiovascular diseases, kidney diseases, and diabetes mellitus. These are assessed during the health check-up so that the patient can avoid them.

It is also recommended to combine the check-up with screening for the early detection of cancer. In this way, the check-up can also serve as cancer screening, for example, for skin cancer. However, other conditions that do not yet cause symptoms can also be detected through a check-up.

The health check-up can also assess your overall fitness and health status. Physical weaknesses are detected early on. They can then be successfully addressed at a younger age, before they lead to serious illnesses in later life.

Procedure for a Check-up

The procedure for a check-up as part of statutory early detection and preventive care screenings is clearly regulated. First, there is a detailed consultation during which

  • your personal medical history (e.g., existing underlying conditions, medications you are taking),
  • illnesses among close relatives (family medical history), and
  • your social environment (social history)

are discussed to create a risk profile.

This is followed by a thorough physical examination as part of the health check-up. The physical examination includes

  • a clinical examination of the entire body (full-body assessment), including inspection of the genital and anal regions,
  • auscultation of the heart and lungs,
  • palpation of the abdomen and major lymph nodes, as well as
  • an assessment of the musculoskeletal system, including reflexes,
  • the skin, and the sensory organs.

In addition, blood and urine samples are collected for laboratory analysis to determine the levels of

  • total cholesterol and glucose in the blood and
  • protein,
  • glucose,
  • erythrocytes (red blood cells),
  • leukocytes (white blood cells), and
  • nitrite in urine

.

Since it may take several days to evaluate the results, a final consultation takes place during a second doctor’s appointment. The patient is informed of the results of the checkup. The doctor discusses with the patient the possible implications for their future lifestyle.

In particular, the patient’s risk profile and any potentially harmful health behaviors should be discussed.

The check-up may raise suspicion of a disease. In this case, the doctor will order further targeted diagnostic tests and, if necessary, initiate treatment.

Preliminary Consultation and Medical History (Anamnesis)

Before beginning the physical examination, the doctor takes the patient’s medical history.

During this process, the doctor inquires about the patient’s past or current illnesses. The doctor also asks about previous health problems and surgeries. Illnesses that have occurred in close relatives are also discussed. Such illnesses include, for example,

The doctor will also ask about any medications the patient is currently taking.

An important part of the medical history is the patient’s individual lifestyle habits and living conditions. These include, for example,

  • dietary habits,
  • alcohol consumption,
  • tobacco use,
  • work-related or personal stress, and
  • physical or athletic activities.

By asking specific questions, the doctor tries to determine whether certain personal or hereditary risk factors are present.

Physical Examination During the Health Checkup

After taking your medical history, the doctor will conduct a thorough physical examination as part of the health checkup. This includes

  • an examination of the genital and anal regions,
  • auscultation of the heart and lungs,
  • palpation of the abdomen and major lymph nodes, as well as
  • an assessment of the musculoskeletal system—including reflexes—the skin, and the sensory organs.

Weight and height are also measured so that the body mass index (BMI) can be calculated.

Calculating BMI During a Health Checkup

The body mass index (BMI) is a measure used to assess body weight. BMI is calculated based on the ratio of weight to height. The formula is:

BMI = (body weight in kg) divided by (height in m)².

BMI is a rather superficial measure, but it is helpful—with some caveats—for assessing whether a person is underweight or overweight.

Examination with a Stethoscope During a Health Checkup

During a health checkup, the doctor listens to the chest (heart and lungs) with a stethoscope. This examination is called auscultation.

The doctor listens for unusual breathing sounds or extrapulmonary sounds (rales and crackles) as well as heart sounds or heart murmurs.

This can help identify, for example,

.

Cardiac and Circulatory Examination

The doctor measures the pulse rate (number of heartbeats per minute). In doing so, the doctor pays attention to both the quality (e.g., soft, weak) and the regularity of the pulse.

This allows for the identification of heart and vascular diseases, such as

Blood pressure is also measured; a reading of 140/90 mmHg or higher is considered high. Even at this early stage of high blood pressure, the risk of

is already increased.

ECG During a Health Checkup

An ECG (electrocardiogram) is used when the doctor detects irregularities in the heart rhythm or other abnormalities. These can also include shortness of breath or chest pain.

The ECG records the electrical activity of the heart muscle. To do this, electrodes are attached to the skin. The ECG can be used to determine, among other things, heart rate and heart rhythm, and to read the electrical activity of the atria and ventricles.

For example, the ECG can provide evidence of

  • arrhythmias,
  • heart attack,
  • thickening of the heart wall,
  • abnormal strain on a ventricle,
  • pericarditis, or
  • myocarditis,

but may also indicate electrolyte imbalances and adverse drug reactions.

Skin Examination During a Health Checkup

During the skin examination, the doctor looks for noticeable skin changes, such as

  • eczema (skin rashes),
  • ulcers,
  • an excessive number of moles, or
  • moles that have changed noticeably.

If the doctor identifies any unusual skin changes, the patient will be referred to a dermatologist for further evaluation.

Laboratory Tests During the Health Checkup

In addition to physical examinations, several laboratory tests are also performed during the health checkup.

By measuring certain levels in the blood and urine, metabolic disorders (e.g., diabetes) or kidney diseases can be detected. This also allows the doctor to assess the risk of developing such diseases.

Blood Tests

As part of the blood test, a blood sample is drawn from the patient and sent to a laboratory. This determines glucose levels (blood sugar) and total cholesterol levels.

To obtain accurate results that can be compared with standard reference ranges, the blood sample must be drawn in the morning on an empty stomach. This means the patient must not have eaten anything before the blood draw.

The results are usually available to the doctor within a few days. The measured blood sugar level should be between 60 and 100 mg/dl in capillary whole blood.

If it is higher than this, it may indicate diabetes mellitus. The doctor will then initiate more targeted diabetes testing. However, a value that is too low can also be an indication of a problem.

The total cholesterol level measured during the checkup should be between 200 and 220 mg/dl.

Higher levels may indicate an unhealthy diet or a lipid metabolism disorder. A total cholesterol level that is too high poses an increased risk of atherosclerosis. Atherosclerosis, in turn, can cause serious cardiovascular diseases such as heart attack and stroke.

Timely treatment of high blood lipid levels is therefore important.

In addition to total cholesterol, your doctor can also have your LDL (“bad” cholesterol) and HDL (“good” cholesterol) levels tested. LDL should be below 160 mg/dl and HDL above 40 mg/dl.

However, the LDL-to-HDL ratio is also important: it should be less than three in a healthy person and even lower in high-risk patients.

Urine Sample

As part of the check-up, the patient provides a urine sample, which is also sent to a laboratory.

The lab then determines the levels of

  • protein,
  • glucose,
  • erythrocytes (red blood cells),
  • leukocytes (white blood cells), and
  • nitrite

in the urine. These values provide the doctor with clues as to whether

  • diabetes,
  • a bacterial infection,
  • malnutrition, or
  • kidney disease

is present.

Comprehensive Health Checkup

The check-up provided as part of statutory early detection and preventive care programs is good but limited. In addition, an extended health check-up may be beneficial.

This is the case, for example, for people who want to resume physical activity after a long break. Additional tests can also be performed during the regular check-up to create an expanded, individualized risk profile. These include, for example,

  • determining the PSA level to detect prostate changes using the PSA test
  • an extended blood test (measuring, for example, electrolytes, vitamins, trace elements, enzymes, and tumor markers)
  • a lung function test
  • an eye exam
  • a stool test (e.g., for fungi, bacteria, parasites, and environmental toxins)
  • Ultrasound examinations (e.g., of the neck vessels, thyroid, abdominal organs, kidneys, bladder, and prostate)
  • a blood flow measurement in the legs
  • a test for Helicobacter
  • An AIDS test
  • Hormone tests
  • Rheumatoid arthritis risk assessment (CCP antibodies)
  • Colorectal cancer screening via immunological stool testing

Sports medicine check-up

A sports medicine fitness evaluation is recommended for all athletes over the age of 35 and for those returning to sports. The sports health check-up often consists of the following tests:

  • Medical history (including a so-called sports medical history)
  • Physical examination, comparable to that of a regular check-up
  • Resting ECG and, if necessary, stress ECG
  • Urinalysis and blood tests (e.g., complete blood count)
  • Advice on choosing the appropriate sport and planning a training regimen based on your health status and fitness level.

However, statutory health insurance plans do not cover the costs of an extended check-up. Doctors offer these check-ups as part of what are known as Individual Health Services (IGeL).

Final consultation following the health check-up

The final consultation will take place a few days after the physical examination and the collection of blood and urine samples. 

The patient will be informed of the results of the check-up. If necessary, the doctor will discuss with the patient the potential implications for their future lifestyle. In particular,

  • the identified risk factors and
  • ways to reduce or avoid behaviors harmful to health

. If necessary, the doctor will provide tips on lifestyle changes, such as regarding diet or exercise. Diabetes mellitus and cardiovascular diseases, in particular, can often be prevented through a healthy lifestyle. This includes, for example,

  • regular physical activity or exercise
  • a balanced and varied diet, avoiding high-fat foods
  • adequate fluid intake (at least 2 liters per day)
  • completely abstaining from smoking
  • moderate alcohol consumption
  • Avoiding stress

Another purpose of the final consultation following the check-up is to inform the patient about the importance of cancer screening tests.

If all test results are normal, the next check-up should take place in three years.
