What are the symptoms of low serotonin

Serotonin is a neurotransmitter that has a very direct relationship with the moods of a person, and we can find in various regions of the central nervous system. In fact, feelings of sadness, anxiety and depression are sometimes very closely related to low levels of serotonin.

The hectic pace of current life, causing stress, as well as a poor diet based on flours and refined sugars seem to be two of the possible causes that cause a decrease in serotonin. Next, we will see what are the most indicative symptoms of low levels of serotonin.

Indications indicating that serotonin has dropped sharply

Symptoms of anxiety

Anxiety is defined as a defense mechanism that helps us to face situations of danger or threat. It is very common in the social field, and especially frequent in people with low socioeconomic level. It presents with irritability and a sense of panic.

Serotonin has a total of 14 different receptors. Recent studies have shown that there is a specific receptor, related to the symptoms of anxiety: it is the 5 HT1A receptor. Apparently a problem in these receptors during youth, could lead to a greater sensitivity to suffer anxiety in adulthood.

Pessimistic attitude

Pessimism is a negative emotional attitude that can lead to a state of depression. The person who suffers from it maintains an attitude of negativity in everything that surrounds it, and even in the future. He identifies with very conformist people who become frustrating to themselves and to those around them.

Low levels of serotonin can cause a pessimistic activity, while other factors such as low sun exposure can also influence it. The sun has a very direct relationship with the production of serotonin, hence the importance of sunbathing moderately to raise serotonin levels.

Low self-esteem

Low self-esteem, when produced by insufficient levels of serotonin, causes a person to feel frustrated and dissatisfied with himself at a certain time. People with low self-esteem tend to compare negatively with others, take into account criticisms that come from other people and are easily influenced.

When the amount of this neurotransmitter increases, the person begins to experience a very significant change in their attitude. She relies more on herself, feels more optimistic and is able to face new challenges. It is a symptom that depression can be controlled by increasing serotonin levels.


Serotonin, along with melatonin, are directly related to a deep and restful sleep, necessary for the body to rest, and so that the next day we are able to get up full of energy.

Serotonin is responsible for facilitating the production of melatonin, so that if serotonin levels are low, melatonin will be affected and as a consequence the dreaded insomnia will appear.

For there to be a correct balance between the production of serotonin and melatonin, it is important to respect the cycle of wakefulness and sleep of our organism. Melatonin is produced more easily in dark environments and conducive to sleep, while the sun's rays are responsible for stimulating the production of serotonin that will be responsible for making us rest later in the night.

Problems to maintain concentration

Concentration is very necessary in our day to day. We need it to perform tasks at work, to hold a conversation, to study or to do chores at home. A deficit of concentration leads us to maintain a certain instability that becomes emotionally unbalanced. In this, a low level of serotonin, may have a lot to do.

Low serotonin influences both concentration and memory. One of the best ways to raise levels is by maintaining a proper diet that elevates serotonin. In this natural way we will achieve excellent results.

Changes in appetite

Appetite changes can be very frequent in people who have a below-normal level of serotonin. These changes can be from stopping eating, to needing to eat certain food groups such as those that contain large amounts of sugar.

One of the functions that serotonin performs, in addition to balancing moods, is to regulate appetite, so a change in normal levels can lead to inappropriate behaviors to ensure good nutrition. Remember that there are foods that increase serotonin and that should be known to include in the diet.

Seasonal changes are the times most prone to occur low levels of serotonin, specifically when the time of autumn-winter arrives. The hours of sun are more reduced and therefore less serotonin is produced, which causes us to feel more apathetic or sad. Maintaining adequate levels is essential to feel active, optimistic and happy.
