one of the factors that can negatively impact the gut and brain’s ability to communicate effectively is the composition of the gut microbiome. “the gut-brain axis is very closely linked to the gut microbiome, which is a collection of microorganisms living in our gut,” said kapoor.
while humans have other microbiomes too, such as in the mouth, on the skin, and in the vagina, the gut is by far the largest one in humans, with trillions of microorganisms present. the mix of bacteria, fungi, viruses and other microbes in the gut is developed shortly after birth and is shaped by diet, medications and environmental factors.
with such a vast reach, it should come as no surprise that the gut microbiome plays a crucial role in various bodily functions, including digestion. “the gut microbiome affects every stage of our lives,” said kapoor. “it helps train our immune system, stabilize our mood, manage stress, and digest our food.” when something disrupts the balance in the gut microbiome, it can lead to signs and symptoms of ibs.
at the first sign of suspected ibs, one must first have a thorough medical check-up to rule out anything more serious. then, if a patient’s symptoms remain, it’s time to seek additional support. “it is not normal to experience pain, discomfort, bloating, and gas after eating,” said kapoor. “always seek a medical opinion, especially if it’s limiting your ability to be active or carry out your usual daily activities.”
