With the onset of the monsoon, doctors are reporting a sharp rise in stomach infections and gut-related health issues, driven by increased humidity, water contamination, and poor food hygiene.
“In the monsoon season, we observe more cases of stomach infections and a higher risk of gut problems like bloating, nausea, and disease,” said Dr. Aditya Shah, General Medicine, Gastroenterology, Apollo Spectra Hospital, Chennai. “The constantly rising humidity, water pollution, and breeding of mosquitoes and flies create an environment where infections thrive.”
Some of the most common infections during this time include bacterial gastroenteritis (stomach flu), caused by contaminated food or water, leading to diarrhoea, vomiting, and abdominal cramps. Parasitic infections such as Giardiasis and Amoebiasis also spike, causing chronic diarrhoea and nausea.
“We also see a rise in food poisoning cases during the monsoon because high humidity promotes the rapid growth of bacteria like E. Coli and Salmonella,” Dr. Shah explained. “These bacteria spread easily through improperly cooked or stored food.”
Other seasonal threats include Typhoid and Cholera, both spread through unsafe water and food, and Hepatitis A and E, viral infections that cause liver inflammation and jaundice. Children are particularly vulnerable to worm infestations from playing in muddy or stagnant water, which can lead to anaemia and digestive problems.
To reduce the risk of infection, Dr. Shah emphasized the importance of basic hygiene practices.
“Simple habits like washing your hands at the right times, avoiding roadside food and open water, and thoroughly cleaning fruits and vegetables can significantly reduce your chances of infection,” he said.
He further advised cooking food well, storing it in sealed containers, and avoiding excessive caffeine and sweetened drinks, which can irritate the gut.
“Physical activity is equally important,” Dr. Shah added. “When you sit all day, digestion slows down. Regular exercise supports digestion and helps prevent gastric conditions.”
Dr. Shah also recommends incorporating probiotics like yoghurt or fermented foods, drinking plenty of water to flush out toxins, and managing stress, which can negatively impact digestion.
“It’s crucial to listen to your body,” Dr. Shah warned. “Persistent diarrhoea, high fever, constant vomiting, blood in stools, or signs of dehydration should never be ignored. Early medical intervention can prevent serious complications.”
With proper hygiene, mindful eating, and early diagnosis, experts say most monsoon-related gut problems can be effectively prevented or treated.
