Gastric discomfort, headache and palpitation are all physiological reactions when a person is nervous. When an individual feels nervous based on his or her own psychological and emotional makeup, he or she may experience one or more of these symptoms. Gastric discomfort is a survival response during stress. When physical or emotional danger is imminent, perceived threats are physically experienced as part of the fight or flight response.
Fighting or escape
People who experience stress in the gastrointestinal tract have a strong fight or escape response to good or bad stress. The range of neurogastric reactions ranges from what is commonly known as "butterflies in the stomach" to vomiting or severe pain. The rumble often accompanied by stomach discomfort is caused by slowing down or stopping digestion accompanied by pressure.
There are many different systems working together in the human body. Some systems are vital to the survival of the body, so they are called important organs. Other systems are necessary, but can be temporarily suspended when physical resources are needed elsewhere. The stomach, as part of the gastrointestinal tract or gastrointestinal tract, is one of these suspensible systems. In times of danger, resources move from the digestive system to vital organs and muscles needed to fight or escape, causing stomach discomfort.
Two operating systems work together in vivo. The central nervous system (cns) is the main headquarters composed of brain, spinal cord and nerve. The central nervous system is responsible for the operation of important organs. However, the central nervous system does not directly operate the digestive system, which is a non-living organ. Instead, the central nervous system sends signals to other operating systems of the body, the enteric nervous system (ens), which is located in the gastrointestinal tract and controls digestion. When the central nervous system sends signals to the nervous system due to stress, the nervous system can trigger reserves used in the immune response, releasing histamines and hormones, leading to gastric reflux and uncomfortable feelings.
