When do we produce serotonin

Postsynaptic receptors are designed to receive the signal from the presynaptic receptor. In the event that these receptors are not functioning properly or there are not enough of them, low serotonin levels can result. Because serotonin affects many bodily processes, having inadequate amounts of the neurotransmitter can lead to both psychological and physiological issues. Some symptoms that are associated with serotonin deficiency can be grouped into the following categories:.

The normal range of serotonin in the blood is roughly — nanograms per milliliter. Treatments for low serotonin levels can include:. Serotonin levels that are too high can be dangerous. In some cases, high levels of serotonin in the blood can be caused by a condition known as carcinoid syndrome. The syndrome is caused by a tumor that produces too much serotonin and can cause symptoms like:.

Another syndrome, known as serotonin syndrome , can occur if levels of the neurotransmitter become dangerously high. Serotonin syndrome is characterized by markedly high levels of serotonin in the body. It can be life-threatening and requires emergency medical assistance.

Common causes of serotonin syndrome include:. People with serotonin syndrome will often suffer from various symptoms that can be mild or severe. Mild symptoms may include:. Moderate symptoms can include:. In severe cases, people may have a high fever, confusion or delirium, sustained clonus or rigidity, rhabdomyolysis the breaking down of damaged muscle , or death.

If you experience any of the above symptoms and have just recently started or increased your dosage of a medication that can affect serotonin levels, seek medical attention right away. People with serotonin syndrome will likely need to be hospitalized for a minimum of 24 hours for observation. If the case is mild and caused by a medication, simply stopping the medication or changing the dosage can relieve the symptoms and restore normal serotonin levels.

Medications that stop the body from producing serotonin may be prescribed to help relieve symptoms and keep the condition from worsening. Some medications that are often used during hospitalization include:. In severe cases, as is often the case with serotonin syndrome, hospitalization for longer than 24 hours may be needed so that a person can be monitored closely for changing or worsening symptoms.

Since serotonin syndrome can be life-threatening, medical attention is required as soon as possible. While in the hospital, patients with serotonin syndrome may have to take medications that paralyze their muscles and may also need to be put on a temporary breathing tube and breathing machine to prevent muscle damage. If you have or suspect you have low levels of serotonin, there are ways you can boost your levels naturally. Since tryptophan is the precursor to serotonin, eating a diet with foods that are either high in the amino acid or could help boost the concentration of it in your blood could help increase levels naturally.

Eggs are one food that can help boost levels of tryptophan. Other foods that you can include in your diet include tofu, salmon, turkey, nuts and seeds, and cheese. Increasing your intake of carbohydrates may also increase your levels of tryptophan. Studies have shown that an increase in carb intake while eating foods high in tryptophan can help tryptophan reach the brain easier. Certain dietary supplements can help restore normal serotonin levels naturally, including:.

Light exposure, also known as light therapy, can improve serotonin levels and decrease symptoms of depression. Research has shown that exposure to sunlight may help the body synthesize serotonin through the skin. Getting enough exercise is important for overall health, but it can also boost serotonin levels naturally.

Exercise triggers the release of tryptophan into the blood, driving serotonin production. There are many types of exercise that can help trigger this response, such as swimming, jogging, hiking, or dancing.

Massage therapy has been shown to help increase serotonin levels while decreasing levels of the stress hormone known as cortisol. Although the prevalence of serotonin syndrome isn't known, one small study looked at how often patients experienced symptoms of the syndrome and found that roughly 7.

The syndrome can typically occur after you start taking a new drug or increase the dosage of an existing medication. Instead, your doctor will perform a physical exam to determine if you have it. Serotonin affects every part of your body. Sometimes, a serotonin imbalance can mean something more serious. Here are 7 serotonin-boosting foods including turkey and cheese. Learn more….

Mental Health. Another study found that when healthy volunteers underwent acute tryptophan depletion to manipulate 5-HT function, they experienced a significantly reduced pain threshold and tolerance in response to a heat thermode. We need enough serotonin to promote blood clotting. The chemical is released in blood platelets to help with wound healing.

Plus, it works to narrow tiny arteries so they form blood clots. A study published in the International Journal of Molecular Sciences found that serotonin acts as a potential therapeutic candidate for enhancing skin healing in burn patients. Researchers found that serotonin significantly accelerated cell migration and improved the wound healing process in vitro and vivo models of burn injuries.

You can have your serotonin levels tested with a blood test. Blood is typically drawn from the vein and sent to the lab for results. People who are at risk of serotonin deficiency or carcinoid syndrome high serotonin levels may need a blood test. Research shows that impaired serotonin function has been associated with psychiatric disorders including depression, anxiety, compulsive behavior, aggression, substance abuse, seasonal affective disorder, bulimia, childhood hyperactivity, hypersexuality, mania, schizophrenia and behavioral disorders.

What causes low serotonin levels? Serotonin is part of a complex system of chemicals and receptors. If you have low serotonin levels, you may have deficiencies in other neurotransmitters, which is what causes such noticeable symptoms.

If you deal with chronic stress or are exposed to toxic substances, like heavy metals or pesticides, you may be at a greater risk of low serotonin.

Other causes may include a lack of sunlight and taking certain medications for a long period of time. There are natural serotonin foods and boosters that will increase levels of serotonin without the need for pharmaceutical drugs.

Some of the best foods include wild-caught salmon, eggs, leafy greens, nuts and fresh vegetables. To maximize the good bacteria in the gut, probiotic foods are also beneficial. Eating or drinking kefir, kombucha, probiotic yogurt and apple cider vinegar will help to improve the health of your gut.

Healthy fats like avocado, coconut oil, extra-virgin olive oil and ghee are also going to help reduce inflammation and promote the natural production of serotonin. Research shows that exercise has beneficial effects on brain function because it modulates neurotransmitters dopamine, serotonin and noradrenaline.

These chemical messengers contribute to exercise, affecting brain function and even improving neurological disorders. This may explain, at least in part, why low levels of serotonin are associated with seasonal affective disorder 0r SAD. Research published in Nutrients shows that reduced intake of tryptophan can lead to significant reductions in certain brain activities that boost happiness.

According to a study, patients are often successful at lowering negative symptoms related to mood disorders, addictions or hormonal problems when they take 6 grams of L-tryptophan per day.

Taking this amount of tryptophan every day for several months has been shown to decrease mood swings, irritability, tension and restlessness. A hormone called melatonin is also critical to the proper functioning of your sleep cycle.

Your body needs serotonin to make melatonin, so not having enough of the neurotransmitter or having too much of it can affect the pattern and quality of your sleep. Your brain has specific areas that control when you fall asleep, regulate your sleep patterns, and wake you up. The parts of your brain that are responsible for regulating sleep also have serotonin receptors. The serotonin-melatonin relationship might also contribute to sleep disruptions like insomnia that are common in people with depression.

When you have any kind of tissue damage, such as a cut, the platelet cells in your blood release serotonin to help heal the wound. Increased serotonin levels cause the tiny arteries known as arterioles of the circulatory system to narrow. As they get smaller, blood flow slows. This narrowing known as vasoconstriction and slowed blood flow are two important elements of blood clotting—a crucial step in the process of wound healing.

Studies have shown that serotonin levels may influence bone density the strength of your bones. Research suggests that high circulating levels of serotonin in the gut might be associated with lower bone density and conditions like osteoporosis. Research suggests that SSRI medications are associated with decreased bone mineral density. Low bone density puts you at a greater risk for fractures. If you are concerned about how taking an antidepressant could affect your bone density, do not stop taking your medication.

Start by talking to your doctor about other risk factors, such as having a family history of osteoporosis or smoking. In addition to altering your mood, serotonin can also influence the frequency and intensity of the sexual feelings you have. Certain antidepressants that increase serotonin levels can have an effect on libido , as elevated serotonin levels have been associated with a decrease in sexual desire.

Serotonin's influence on libido is also somewhat related to the neurotransmitter's relationship to another chemical in the brain: dopamine. For example, a study of women with hypoactive sexual desire disorder HSDD indicated that symptoms of the condition were associated with increased serotonin activity and reduced dopamine activity. Depression and other mood disorders that are linked to serotonin are multifactorial , meaning there is more than one reason they occur.

Having low serotonin levels is not, on its own, enough to cause depression. Low levels can, however, contribute to mood, sleep, digestive, and other issues. There's no single cause of low serotonin levels, but it typically occurs for one of two reasons: not having enough serotonin or inefficient use of the serotonin you have. In the first scenario, you have low levels of serotonin because your body is not producing enough to maintain normal levels.

Your body might not be able to produce enough serotonin because of other factors, such as nutritional and vitamin deficiencies. For example, low levels of vitamin B6 and vitamin D have both been linked to decreased levels of serotonin. Tryptophan , an essential amino acid involved in serotonin production, can only be obtained through diet.

The other reason you might have low serotonin is that while your body is making serotonin, it is not using it effectively. This can happen if you don't have enough serotonin receptors in your brain, or if the ones you have don't work well for example, they absorb and break down serotonin too quickly. Depression is known to be associated with chemical imbalances in the brain.

While serotonin's role in depression is more complex than an imbalance, it is believed to play a key role. Increasing how much serotonin is in the brain appears to improve communication between brain cells, which in turn lifts mood and reduces symptoms of depression. This is why prescription antidepressant medications are used to treat clinical depression and other mood disorders.

There are also natural ways to increase serotonin levels. Everything from the food you eat to how much sunlight you get can affect how much serotonin your body has, as well as how effectively it can use it. SSRIs are the most commonly prescribed antidepressants worldwide. These drugs are used to reduce the symptoms of moderate to severe depression by increasing the amount of serotonin in the brain. When brain cells send signals to one another, they release neurotransmitters, including serotonin.

Before they can send the next signal, the cells must reabsorb and recycle the neurotransmitters they released. This process is called reuptake. Examples of SSRIs that are commonly prescribed to treat depression and other mood disorders include:. Drugs in this class are not solely classified as SSRIs, but rather, as serotonergic antidepressants.

Trintellix vortioxetine is a similar drug. Another group of serotonin-based medications for treating depression is known as serotonin-norepinephrine reuptake inhibitors SNRIs. These drugs work similarly to SSRIs in that they block the reuptake of serotonin, but they also work on norepinephrine , another neurotransmitter that affects mood. Two older classes of antidepressants also affect serotonin levels: tricyclic antidepressants TCAs and monoamine oxidase inhibitors MAOIs.

TCAs appear to block the reabsorption of serotonin and norepinephrine, which effectively increases the amounts available in the brain. Examples of TCAs include:. MAOIs, on the other hand, block the effects of the monoamine oxidase enzyme, which breaks down serotonin, epinephrine, and dopamine. Preventing these neurotransmitters from being broken down effectively increases the amounts available in the brain.

Examples of MAOIs include:. Many foods naturally contain serotonin, but your body also needs other nutrients, such as tryptophan, vitamin B6, vitamin D, and omega-3 fatty acids, to produce the neurotransmitter. Foods that are good sources of these key nutrients include:. Eating a high-fiber diet that is rich in fruits and vegetables will help keep your gut bacteria healthy.
