Serotonin is a neurotransmitter playing a crucial role in regulating mood, appetite, and sleep. It is often referred to as the “feel-good hormone” because of its impact on overall well-being and happiness. However, a deficiency in serotonin levels can lead to various negative mental and physical symptoms, including depression, anxiety, insomnia, and more.
What is Serotonin, and How Does it Work?
Serotonin is a chemical messenger produced by nerve cells and released into the brain and bloodstream. It helps to regulate mood, appetite, and sleep by transmitting signals between nerve cells. Serotonin acts as a natural antidepressant, blocking negative thoughts and feelings and promoting happiness and well-being.
Causes of Serotonin Deficiency
Several factors can contribute to a Serotonin Deficiency, including genetics, stress, and an imbalanced diet. Additionally, certain medications and medical conditions can also have an impact on serotonin levels. For example, certain antidepressants, pain medications, and antibiotics can lower serotonin levels, while medical conditions such as hypothyroidism, liver disease, and Parkinson’s disease can also affect serotonin production and release.

- Depression: Serotonin is known as the “feel-good hormone,” Low levels can result in sadness, hopelessness, and a lack of interest in things that were once enjoyed.
