Thyroid gland
Small gland, big effect: the thyroid gland at the centre of metabolism
The thyroid gland is only a few centimetres in size, but its effect on the body is enormous. It regulates your energy consumption, your body temperature, your pulse - and even your mood. If it gets out of balance, this can have far-reaching consequences: Weight gain, exhaustion, hair loss, concentration problems, nervousness or feeling cold - all of these can be an indication that your thyroid gland is out of sync.
What many people don't realise is that thyroid disorders often develop slowly. Symptoms are misclassified or not noticed at all. This makes it all the more important to regularly check the relevant blood values - especially if diffuse symptoms occur that cannot be explained.
Thyroid values in the lab: what really counts
The most important laboratory parameters for the thyroid gland are TSH, fT3 and fT4 - i.e. the control hormone from the brain and the two active thyroid hormones. They show how well the thyroid gland is functioning and whether it is producing enough hormones. Antibodies can also be determined if an autoimmune disease such as Hashimoto's is suspected.
TSH is a sensitive marker: even small shifts can have noticeable effects - even if the values are still "within the normal range". That's why it's not just the laboratory number that is decisive, but the connection to the symptoms. In our practice, we attach great importance to this individual interpretation: what do your values say - and what do they mean for your everyday life?
Sport & thyroid: the underestimated interplay
If you exercise regularly, you should keep a close eye on your thyroid levels. Because an underactive thyroid will slow you down - both physically and mentally. Many athletes report stagnating performance despite intensive training. Conversely, an overactive thyroid can speed up your heart rate, lead to sleep problems and break down your muscles.
The thyroid gland is particularly challenged by cycle-dependent fluctuations, hormonal changes or diets. It is therefore a key control organ for people who are active in sport - and should be regularly analysed in the laboratory.
Our analysis: personal, clear and medically sound
In our practice, we offer you targeted thyroid diagnostics - no mass processing, but individual assessment of your symptoms and values. After the venous blood sample is taken, we discuss the results in detail: Are there any indications of an incipient hypo- or hyperthyroidism? Does your body need support? And how can your symptoms be better categorised?
Often it's just a small hormonal shift that makes the difference - but only if you recognise it. That's exactly our goal: to give you clarity and help you get back into balance - without panic, but with medical precision.
Frequently asked questions
Our practice focuses on your health and well-being.
What symptoms indicate a thyroid disorder?
Typical symptoms are tiredness, weight gain, hair loss, sensitivity to cold, depressive moods or restlessness. Many people only realise when they suddenly "function differently" than usual - mentally or physically.
What does the TSH value indicate?
TSH is the control hormone from the pituitary gland. It stimulates the thyroid gland to produce hormones. A high TSH value usually indicates hypothyroidism, a low value indicates hyperthyroidism - but the overall picture is decisive.
What is the difference between fT3 and fT4?
fT4 is the "precursor", fT3 the more active hormone. Both are important for understanding the activity of the thyroid gland. In some cases, fT3 is normal although fT4 is too low - or vice versa.
Do I have to be sober for the blood test?
Not mandatory - but best in the morning between 8 and 10 a.m., because the values can fluctuate depending on the time of day.
Can thyroid problems also be caused by stress?
Yes - chronic stress affects the axis between the brain, thyroid and adrenal glands. Cortisol in particular can disrupt the hormonal balance.
How often should I have my thyroid checked?
Every 1-2 years if the values are normal. If symptoms are conspicuous or thyroid problems are known, much more frequently.
Do you also test antibodies?
Yes - if autoimmune diseases such as Hashimoto's or Graves' disease are suspected, we determine TPO antibodies and, if necessary, TRAK or TG-AK.
Is treatment always necessary if the values deviate?
Not necessarily. Some changes can be observed. Others can be influenced by micronutrients or lifestyle changes. Medication is only necessary if there is a clear need for action.
Does the health insurance company cover the examination?
We bill according to GOÄ. Private health insurance companies generally cover the costs, statutory health insurance companies do not.
Is the thyroid gland also important for athletes?
Absolutely - it controls your basal metabolic rate, your energy and your performance. An imbalance can slow down the effects of training, no matter how hard you train.
