The most common symptoms of low dopamine

Dopamine is a neurotransmitter or chemical substance that plays an important role in sending signals from the brain to the body. It occurs naturally in different key parts of the brain and is important for functions such as motor skills, cognitive abilities, and reproduction.

This neurotransmitter soars in anticipation of important upcoming events, plays a key role in the body’s reward and motivation system, and also affects memory.

Although dopamine accounts for only a small portion (less than 1%) of brain neurons, it still performs these important functions. In the right amount, this neurotransmitter is essential for brain function, but when this amount is lower than the prescribed point, it will also have unexpected consequences for the body. Dopamine deficiency is related to neurodegenerative diseases in the body.

To understand the effects of low dopamine, we will first examine the signs and causes of this condition. Then, we will learn about the diseases most commonly associated with dopamine deficiency in order to gain a deeper understanding of their effects. Finally, we will share the methods to keep the body producing this important neurotransmitter.

Symptoms of low dopamine

Because of its association with diseases such as schizophrenia and Parkinson’s disease, dopamine deficiency may show similar characteristics to these diseases. These characteristics include:

  • Chronic back pain
  • Persistent constipation
  • Weight fluctuations
  • Difficulty swallowing or swallowing
  • sleep disorder
  • fatigue
  • Difficulty paying attention
  • Reduce libido
  • Hallucinations and delusions
  • Aspiration pneumonia
  • upset

Causes of low dopamine

Many factors can cause a decrease in dopamine in the body. These include sleep deprivation, obesity, drug abuse, saturated fat and stress. Below is a detailed introduction of each.

lack of sleep

In addition to drinking coffee in the morning, dopamine is one of the reasons that make you feel refreshed and alert in most mornings. This wakefulness is promoted by dopamine receptors, especially D2 receptors. These receptors help regulate the function of dopamine in the body.

However, sleep deprivation reduces the number of D2 receptors in important parts of the brain. If this happens, the transmission and production of dopamine will be affected.

In fact, for diseases with low dopamine levels such as Parkinson’s disease, most people feel excessive sleepiness during the day.


Obesity is related to many health conditions, but a lesser-known effect is its role in down-regulating or reducing the amount of dopamine in the brain.

As with sleep deprivation, obesity causes a decrease in D2 receptors in the brain. This becomes especially evident when compared with the number of receptors in non-obese people.


During early use, certain medications may cause an increase in dopamine. Cocaine is a drug known to cause euphoria and increase dopamine levels after use.

However, long-term use of these drugs will certainly bring diminishing returns, especially when dopamine production is involved.

As the production of dopamine continues to increase after drug use, the brain will intervene to reduce the number of available dopamine receptors.

Saturated fat

When you eat fried chicken, butter bread, chocolate, and other foods rich in saturated fat, your brain will be filled with dopamine because of the happiness you get from these foods, which is understandable.

However, although these foods can only produce short-term enjoyment. Over time, continuous observation of a high-fat diet can disrupt the function of the central nervous system that produces dopamine. When it is destroyed, this can lead to dopamine deficiency.


The benefits of stress are few, and maintaining optimal dopamine levels is not one of them. When you often face stressors such as financial difficulties, interpersonal problems, work pressure, etc., this will affect your body’s dopamine production. Over time, this can also lead to a lack of neurotransmitters in the body.

Disorders related to dopamine deficiency

Major depression

Major depression is one of the most serious mental and behavioral disorders. It is characterized by long-term depression or lack of interest in normally attractive activities. This loss of interest is often referred to as anhedonia.

However, in addition to loss of interest, lack of anhedonia is also related to the interruption of the brain’s reward process. The usual expectations, motivations, and decision-making stages involved in the reward system are greatly affected. This change is related to the dysfunction of the dopamine system.

It is well known that the decline in dopamine levels is the basis for the symptoms associated with major depression.


This obstacle is related to the abnormal interpretation of reality. Schizophrenia is a serious mental health condition that affects a person’s ability to think, act, or express themselves.

It can usually be diagnosed by symptoms such as hallucinations, delusions, and abnormal body gait. These signs may also be due to an imbalance of dopamine in the body.

Low levels of dopamine are related to other signs, such as anhedonia, inability to complete tasks, and insufficient motivation to participate in social interactions.

Parkinson’s Disease

Parkinson’s disease is a neurological disease. It can be identified by tremor, which may be barely noticeable at first, and then develop into obvious tremor, muscle stiffness, or delayed movement. This obstacle may also cause balance problems during exercise.

Parkinson’s disease is the result of many factors, one of which is the decrease in the production of dopamine in the brain. When dopamine is deficient, this can lead to significant movement difficulties associated with this condition.

How to treat low dopamine levels

Low dopamine levels can cause negative reactions throughout the body. In order to prevent and remedy this defect, the following methods may be useful.


Exercising through running, swimming, dancing or other forms of exercise can help increase dopamine levels in the body. Studies conducted on animals have shown that during physical activity, certain parts of the brain are flushed with dopamine. This is why exercise sometimes produces orgasms.

Natural source

Your body’s supply of dopamine may be supported by external sources. Natural sources such as bananas, plantains, and avocados have been found to contain high levels of dopamine. Apples, eggplants, spinach and tomatoes are also considered sources of dopamine. Protein is also an important part of the production process of dopamine.


Probiotics may receive more attention in promoting intestinal health, but this type of bacteria is not only an important part of the human microbiome, but may also contribute to the production of dopamine and other neurotransmitters.


It is not 100% sure how music affects the brain, but some songs make you feel chills and make you mellow for a reason, especially when listening to it can make you refreshed.

The last potential may be due to the ability of music to stimulate the production of dopamine in the brain. This will make you feel happy and excited when listening to music, and will help increase your dwindling dopamine levels.

Very good sentence

The right amount of dopamine can make you feel happy, excited and motivated when doing activities. However, when the body does not consume enough of this neurotransmitter, things start to get worse. This may be due to genetic predisposition, obesity, stress and other reasons.

When this happens, you often feel tired, constipated, depressed, sleep disorders, and other negative reactions.

Fortunately, using a correct diet consisting of bananas, probiotics and other fruits and protein can increase the body’s dopamine levels. You can also repair dopamine by listening to music and exercising regularly.
