What Could Trigger Nausea? 14 Possible Causes

Emotional Stress

Inability to focus, avoidance, worrying, and nervousness are some emotional symptoms of anxiety and stress. These symptoms are widely known as manifestations of extreme stress. But these conditions can also have physical symptoms such as palm sweating, uncontrollable shaking, and fast heartbeat. These physical symptoms are there in response to the fight or flight mechanism of the body. During emotional stress, the body anticipates the danger it faces.

Recent studies show that emotional stress can cause nausea. This claim is related to the brain and digestive system. The digestive system has the second largest number of nerves. Experts even coined the title “second brain” to the gut. When facing stressors, the brain sends multiple signals to the body, triggering the release of chemicals and hormones. This reaction will cause nausea. In addition, the release of hormones triggers the brain to send messages through the neurotransmitters. 

During times of emotional stress, the body may experience uneasiness and discomfort. Nausea caused by stress can make a person sick. In addition, as the stomach contracts due to the nerves found in it, the body receives the message that it is undergoing a stressful condition.
