Low levels of serotonin can cause changes in mental health, such as sadness, depression, irritability, sleep problems and aggression.
Serotonin is a neurotransmitter mostly known as a hormone that is not only responsible for maintaining balanced levels of our mood but also comply with the following:
It works as a transmitter regulating the intensity of the signals that the neurons emit.
Regulates gastrointestinal functions and movements.
It helps the formation of blood clots.
Stimulates the vomiting center in the brain causing nausea in case of ingesting something toxic or irritative.
Regulates calcium levels in bones.
Maintains the quality of dreams.
Adjusts the levels of libido and sexual functions.
Because serotonin is involved in a variety of processes within the human body, there may be many symptoms when we have a deficiency.
If you want to know more about the precise symptoms that indicate a low level of serotonin in your body, we invite you to continue reading this article.
1. Feelings of anxiety
Usually, people who have low levels of serotonin in their body suffer from anxiety, and in many cases, it can be accompanied by depression.
At the same time, low levels of serotonin may also involve:
Generalized anxiety disorder.
Obsessive compulsive disorder (OCD).
However, they can be relieved or disappear when serotonin medications are used.
2. The digestive problems
Serotonin is not only associated with gastrointestinal processes, 95% of it occurs within the intestine.
That is why the deficit of this hormone directly affects the gastrointestinal processes to the point of developing an irritable bowel syndrome.
However, by increasing the levels of said hormone, this condition returns to normal.
3. Emotional hypersensitivity
As is well known, this hormone is directly associated with the emotional stability of people, so a low level could cause greater sensitivity than usual.
This can get to the point where any comment feels worse than it really is.
4. Serotonin and carbohydrates
If a person has low levels of serotonin it is normal for their body to try to compensate while eating carbohydrates and sweets.
This type of food automatically increases serotonin levels in the brain.
For that reason it is that you feel so much satisfaction when we eat foods full of sugar, because our serotonin levels rise significantly.
When serotonin levels are lower than they should be, it begins to affect our daily activities and causes us much fatigue.
It is usual for people who suffer it to have a feeling of:
Lack of energy.
Lack of motivation.
6. The libido
Levels that are too high or too low can directly affect libido, better known as sexual desire.

When you remove or add excessively an important hormone to complete these processes such as serotonin, everything is affected.
7. Difficulty falling asleep
The lack of this hormone can cause a lot of problems at bedtime, such as:
Difficulties to obtain a deep sleep.
Problems to stay asleep during the night.
Inability to relax.
And this is because serotonin is part of the process of people’s biological clock, the same one that is responsible for making our body rest at night.
8. Sensitivity to noise

This is because the stress in this person is so high that even the softest sounds seem very exaggerated.
9. Constant mood swings
When you have low levels of serotonin it is common for people to suffer from constant mood swings as well.
This is directly associated with the fact that serotonin is responsible for keeping our mood levels stable.
For that reason it is normal to see how a person presents severe changes in their mood in a short period of time, such as:
Usually none of these symptoms are permanent once the serotonin in the body is replenished, either by medication or naturally, everything returns to normal.
