How can anxiety cause nausea or IBS
In: 1
Good question!
Anxiety puts your body into ‘fight/flight’ mode, which is the sympathetic nervous system. This means your body is adapting your body to move quickly, which is why you breathe faster and your heart rate goes up.
Well, what do you not need while running from a bear or a particularly angry grandmother? Your stomach. So your body inhibits your stomach muscles, causing the stomach contents not to move as much, which may lead to nausea, especially if you had a large, spicy, or fizzy meal.
I’m not too sure about IBS, as I would assume that the bowel muscles would also be inhibited. Perhaps contents staying still in your bowels lets the bacteria eat more, leading to gas/diarrhea?
I hope this helps!
