Article overview

What is a check-up examination?

The health check-up is used for the early detection of common diseases that

  • can be treated effectively and
  • whose early stage can be determined by diagnostic measures.

These include

These diseases increase from the age of around 35. This is why health insurance companies cover the costs of a basic check-up for all people aged 35 and over every three years.

The health check-up is carried out by family doctors (general practitioners, general practitioners and internists).

The health check-up consists of various partial examinations:

  • a medical history,
  • a physical examination including a blood pressure measurement
  • a urine test for blood, protein and glucose (sugar) and
  • the determination of cholesterol and glucose in the blood.

After the examinations have been evaluated, a final consultation takes place. The doctor informs the patient of the findings. If necessary, he or she will also make recommendations for further examinations.

Aim of the health check-up

The check-up examination aims to identify illnesses that often do not show any physical symptoms in the initial phase. For this reason, people who feel fit and physically healthy should also have a health check-up.

Regular check-ups are the only way to detect changes in the body at an early stage and avert health risks. In this way, suspected cases can be diagnosed in more detail in further examinations and any illnesses detected can be treated in good time. This increases the chances of recovery.

In addition, a check-up can identify and change behaviors that are harmful to health.

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

It is also recommended that the check-up is carried out together with an examination for the early detection of cancer. For example, the check-up can also serve to prevent cancer of the skin. However, other diseases that do not yet show any symptoms can also be detected with the help of a check-up examination.

The health check-up can also determine the general state of fitness and health. Physical weaknesses are detected at an early stage. They can then be successfully corrected at a younger age before they lead to serious illnesses in old age.

Procedure of a check-up examination

The check-up examination procedure as part of the statutory early detection and preventive examinations is clearly regulated. The first step is a detailed discussion in which

  • your own medical history (personal medical history; e.g. existing underlying illness, medication taken),
  • the illnesses of close relatives(family history) and
  • the social environment (social anamnesis)

and a risk profile is created.

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

  • A clinical examination of the entire body(full body status), including inspection of the genitals and anal region,
  • listening to the heart and lungs
  • palpation of the abdomen and important lymph nodes and
  • assessment of the musculoskeletal system including reflex status,
  • the skin and the sensory organs.

In addition, blood and urine samples are taken in order to determine the values for

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

in the urine.

As the evaluation of the findings can take several days, a final consultation takes place during a second appointment with the doctor. The patient is informed of the results of the check-up examination. The doctor will discuss the possible consequences with regard to the patient's future lifestyle.

In particular, the patient's risk profile and any behavior that may be detrimental to health should be discussed.

The check-up examination may reveal a suspected illness. In this case, the doctor will arrange for further targeted diagnostics and, if necessary, initiate treatment.

Preliminary consultation and medical history (anamnesis)

Before starting the physical examination, the doctor will take a medical history.

He will inquire about the patient's previous or current illnesses. He will also ask about previous health problems and operations. Diseases that have occurred in close relatives are also a topic of discussion. Such illnesses include

Any medication taken will also be asked about.

Individual lifestyle habits and living conditions are also an important part of the medical history. This includes, for example

  • Dietary habits,
  • alcohol consumption,
  • nicotine consumption,
  • professional or private stress and
  • physical or sporting activities.

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

Physical examination during the health check-up

After taking a medical history, the doctor will carry out a thorough physical examination during the health check-up. This includes

  • Examination of the genitals and anal region,
  • listening to the heart and lungs
  • palpation of the abdomen and important lymph nodes and
  • assessment of the musculoskeletal system including reflex status, skin and sensory organs.

Weight and height are also determined so that the body mass index can be calculated.

Determination of the BMI during the health check-up

The body mass index (BMI) is a measure for assessing body weight. The BMI is calculated from weight in relation to height. The formula is

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

The BMI is a rather superficial value, but is useful for assessing whether you are underweight or overweight.

Examination with the stethoscope during the health check-up

During the health check-up, the doctor listens to the chest cavity (heart and lungs) with a stethoscope. This examination is known as auscultation.

The doctor listens for unusual breathing noises (rales and rasping noises) and heart sounds.

This allows, for example

recognize.

Cardiovascular examination

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

This allows conclusions to be drawn about heart and vascular diseases, such as

Blood pressure is also measured, which is considered too high from a value of 140/90 mmHg. Even at this incipient level of high blood pressure, the risk of

increased.

ECG during a health check-up

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

The ECG records the electrical activity of the heart muscle. Electrodes are attached to the skin for this purpose. Heart rate and heart rhythm can be determined from the ECG and the electrical activity of the atria and ventricles can be read.

For example, the ECG can provide indications of

but also for electrolyte disorders and adverse drug reactions.

Examination of the skin during the health check-up

When inspecting the skin, the doctor will look for any noticeable skin changes, such as

  • Eczema (skin rashes),
  • ulcers,
  • an excessive number of moles or
  • conspicuously altered moles.

If the doctor detects abnormal skin changes, a referral is made to a dermatologist for more detailed clarification.

Laboratory examination during the health check-up

In addition to the physical examinations, a number of laboratory tests are also carried out during the health check-up.

By determining certain values in the blood and urine, metabolic disorders (e.g. diabetes) or kidney diseases can be detected. The doctor can also assess the risk of developing such diseases.

Blood values

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

In order to obtain exact values that are comparable with the standard tables, the blood sample must be taken in the morning and on an empty stomach. The patient must therefore not have eaten anything before the blood sample is taken.

The result is usually available to the doctor after a few days. The blood glucose value determined should be between 60 and 100 mg/dl in the capillary whole blood.

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

The total cholesterol level determined during the check-up should be between 200 and 220 mg/dl.

Higher values can be an indication of an incorrect diet or a lipometabolic disorder. Too high a total cholesterol value represents an increased risk of hardening of the arteries(arteriosclerosis). In turn, arteriosclerosis can cause serious cardiovascular diseases such as heart attacks and strokes.

Timely treatment of high blood lipid levels is therefore important.

In addition to the total cholesterol, the doctor can also have the LDL value ("bad" cholesterol) and the HDL value ("good" cholesterol) determined. The LDL should be below 160 mg/dl and the HDL above 40 mg/dl.

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

Urine sample

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

The laboratory then determines the values for

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

in the urine. The values give the doctor an indication of whether

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

is present.

Extended check-up examination

The check-up examination regulated as part of the statutory early detection and preventive examinations is good, but limited. In addition, an extended health check-up may be useful.

This is the case, for example, for people who want to start exercising again after a long break. Additional examinations can also be carried out during the regular check-up to create an extended individual risk profile. These include, for example

  • determination of the PSA value to detect prostate changes with the PSA test
  • an extended blood test (determination of electrolytes, vitamins, trace elements, enzymes, tumor markers, for example)
  • a lung function test
  • an eye test
  • a stool test (e.g. for fungi, bacteria, parasites, environmental toxins)
  • Ultrasound examinations (e.g. of the neck vessels, thyroid gland, abdominal organs, kidneys, urinary bladder, prostate)
  • a blood flow measurement in the legs
  • a test for Helicobacter
  • an AIDS test
  • hormone determinations
  • a rheumatism risk determination (CCP antibodies)
  • Early detection of bowel cancer by means of immunological stool examination

Sports medical check-up examination

A sports medical aptitude test is recommended for all sportspeople over the age of 35 and for those returning to sport. The sports health check-up often consists of the following examinations:

  • Medical history (this also includes a so-called sports history)
  • Physical examination, which is comparable to the regular check-up
  • Resting ECG and, if necessary, exercise ECG
  • Urine test and blood test (e.g. small blood count)
  • Advice on the choice of suitable sport and training planning based on your state of health and fitness.

However, statutory health insurance companies do not cover the costs of an extended check-up. Doctors offer these check-up examinations as part of so-called individual health services(IGeL).

Final consultation during the health check-up

The final consultation will take place a few days after the physical examination and blood and urine samples have been taken.

The patient will be informed of the results of the check-up examination. If necessary, the doctor will discuss the possible consequences with regard to the patient's future lifestyle. In particular

  • the risk factors identified and
  • a possible reduction or avoidance of behavior that is harmful to health

be discussed. If necessary, the doctor will give tips on lifestyle changes, for example with regard to diet or exercise. Diabetes mellitus and cardiovascular diseases in particular can often be prevented by adopting a healthy lifestyle. This includes, for example

  • Regular physical activity or exercise
  • a balanced and varied diet, avoiding fatty foods
  • Adequate fluid intake (at least 2 liters per day)
  • complete cessation of smoking
  • moderate alcohol consumption
  • avoidance of stress

Another task of the final check-up consultation is to make the patient aware of the importance of cancer screening examinations.

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