Physical symptoms of having low serotonin levels are chronic fatigue, hot flashes, migraines, sleep issues and gastrointestinal pain, reports Progressive Health. Emotional symptoms include depression, emotional sensitivity, irritability, numbness and obsessive-compulsive disorder. Food does not contain serotonin as a nutrient, according to Healthline.
Nonetheless, foods that contain tryptophan may be very beneficial in raising serotonin levels. Tryptophan is the amino acid that makes up serotonin. Eating eggs, cheese, pineapples, tofu or salmon with a helping of carbohydrates can increase serotonin. Eating carbohydrates releases insulin into the body, allowing easy absorption of amino acids into the heart, muscles and organs.
It is possible to overcome difficulties caused by low serotonin levels with exercise, meditation, spending time outdoors or taking serotonin supplements, states Progressive Health. Serotonin medication includes selective serotonin reuptake inhibitors and serotonin norepinephrine reuptake inhibitors, which are also referred to as antidepressants.
Serotonin performs as a neurotransmitter, sending messages from one part of the brain to another, notes WebMD. Serotonin is created in the brain, but nearly 90 percent is found in blood platelets and the digestive tract. The brain hosts about 40 million cells, and serotonin influences the majority of them. This includes brain cells connected to appetite, learning and sexual desire. Serotonin also affects the tasks of the cardiovascular system.
