The gut and brain communicate constantly, so emotional stress can change how the digestive system works. Anxiety can speed up or slow down the bowel, increase acid and sensitivity, and make existing conditions such as irritable bowel syndrome (IBS) flare. Symptoms can include butterflies, nausea, urgent diarrhoea, constipation, cramping and bloating.
Managing stress often improves these symptoms. Helpful approaches include regular exercise, good sleep, relaxation or breathing techniques, limiting caffeine and alcohol, eating regular balanced meals, and talking therapies for ongoing anxiety.
While stress is a common cause, do not assume it is the only one. See a doctor if digestive symptoms are persistent, severe, or come with warning signs such as blood in the stool, unexplained weight loss, persistent vomiting, or symptoms that wake you at night, so physical causes are not missed. Support is also available if anxiety is affecting your daily life.
