It's thought to have a good influence on mood, emotion and sleep. After carrying a message, serotonin is usually reabsorbed by the nerve cells known as "reuptake".

SSRIs work by blocking "inhibiting" reuptake, meaning more serotonin is available to pass further messages between nearby nerve cells. It would be too simplistic to say that depression and related mental health conditions are caused by low serotonin levels, but a rise in serotonin levels can improve symptoms and make people more responsive to other types of treatment, such as CBT.

SSRIs are usually taken in tablet form. When they're prescribed, you'll start on the lowest possible dose thought necessary to improve your symptoms. SSRIs usually need to be taken for 2 to 4 weeks before the benefit is felt. You may experience mild side effects early on, but it's important that you don't stop taking the medication. The brain is made up of millions of interconnected brain cells neurons.

Messages travel along these cells rather like electricity down a wire, but when the message reaches the end of the neuron, it has to jump the gap synapse to the next cell or group of cells. To do this the neuron releases tiny amounts of a neurotransmitter into the gap. Serotonin is one of these neurotransmitters. The job of your nerve cells is to send messages back and forth like a telephone wire.

These chemicals are sent out by one nerve cell into the space between it and the next. The next cell in line gets the message once those chemicals get to it from across the gap. That nerve cell then releases a chemical toward the next nerve cell so it gets the message. A key gene for this process is hSERT which has the instructions for making a serotonin transporter. To put it simply, their nerve cells are whispering when they should be speaking out loud.

In order to allow the nerve to recover and receive the next message, the body has a clever way of removing the neurotransmitter from the receptors, and allowing it to be taken back into the originating nerve re-uptake. The SSRIs slow down the collection of serotonin by transporters like hSERT and the process of returning the serotonin to the end of the neuron it comes from. This is thought to mean that serotonin stays in the space between the cells longer and increases the chances that the second cell will get the message.

Serotonin is a result of tryptophan, a component of proteins, combining with tryptophan hydroxylase, a chemical reactor. Together, they form 5-HT, or serotonin. The intestines and the brain produce serotonin. It is also present in blood platelets and plays a role in the central nervous system CNS. Occurring throughout the body, it appears to influence a range of physical and psychological functions.

Serotonin is also present in animals, plants, and fungi. For this reason, some people have looked at food as a possible source of serotonin. Serotonin cannot cross the blood-brain barrier. This means that the brain must produce any serotonin that it needs to use. Treatments for depression and other mental health issues do not supply serotonin directly but trigger reactions that can boost serotonin levels in the brain.

However, research suggests that sources of serotonin in other areas, such as the digestive system, may work independently of serotonin in the brain. This could have implications for the treatment and prevention of various physiological conditions, such as bone degeneration. As a neurotransmitter, serotonin relays signals between nerve cells and regulates their intensity.

Scientists believe it plays a role in mood and the CNS and affects functions throughout the body. It may have an impact on:. Scientists do not know precisely what causes depression, but one theory is that it stems from an imbalance of neurotransmitters in the body.

Doctors commonly prescribe selective serotonin reuptake inhibitors SSRIs as antidepressants. Fluoxetine Prozac is one example. Normally, the body reabsorbs a neurotransmitter after it has transmitted its neural impulse. SSRIs stop the body from reabsorbing serotonin, leaving higher levels of serotonin to circulate. Many people find SSRIs help relieve their symptoms, although the link between depression and serotonin remains unclear.

One problem for researchers is that, while they can measure serotonin levels in the bloodstream, they cannot measure its levels in the brain.

As a result, they do not know whether serotonin levels in the bloodstream reflect those in the brain. It is also impossible to know whether SSRIs can really affect the brain.
