The gut and brain are connected through the gut-brain axis, allowing them to influence each other’s functions. An imbalance in the gut microbiome, known as dysbiosis, can contribute to anxiety by affecting mood, cognition, and mental health. This imbalance may result from a loss of beneficial bacteria, the growth of harmful bacteria, or reduced diversity in gut bacteria. Inflammation, caused by gut issues like IBS, can also lead to anxiety. Additionally, the gut produces serotonin, and disruptions in its balance may affect anxiety symptoms. Diets high in processed foods, sugar, alcohol, and caffeine may worsen anxiety, while prebiotics, probiotics, fiber, and omega-3 fatty acids can support gut health and reduce symptoms. Managing stress is also crucial for maintaining a balanced gut microbiome and mental well-being.
