Serotonin

What is serotonin?

Serotonin (the so-called happiness hormone)  is a biogenic amine that acts as a hormone and neurotransmitter.  Serotonin is produced in the hypothalamus, but also to a large extent in the small intestine and in the pineal gland and platelets. It has multidirectional effects: it regulates the contractile function of the gastrointestinal tract and blood vessels, and affects platelet aggregation. Reduced levels of serotonin can lead to sleep disorders, impaired concentration, reduced sexual desire, lack of appetite or overeating such as sweets, lowered mood and even depression. Excess serotonin causes agitation, anxiety, palpitations, sweating, increased blood pressure, headaches, diarrhea. Increased levels of serotonin are also observed in a rare cancer of the gastrointestinal tract -  carcinoma.

Why is it important to test serotonin levels?

Serotonin deficiency is associated with depressive disorders, increased appetite or lack thereof, insomnia and irritability. An excess, on the other hand, causes such ailments as elevated blood pressure and heart rate, seizures, chills, diarrhea and vomiting.

What does the test consist of?

The test involves taking a sample of venous blood. A few days before the test, you should refrain from foods containing large amounts of it: pineapples, bananas, kiwis, dried fruits and chocolate, eggs, nuts, almonds, tofu.

Because of the short period of stability of serotonin, you should make sure in advance at which collection point you will be able to take a blood sample.

Waiting time for the result: up to 14 working days.
