Rains bring much-needed respite from the sweltering, scorching heat, but off-season showers can take a toll on one’s digestive system. Acidity, indigestion, vomiting and gastritis are common problems that rear their ugly head during this period. To learn why it happens, and keep such gut issues in check, indianexpress.com reached out to health experts and got some clarity.
Dr. Anupama N K, Senior Consultant – Medical Gastroenterology, Aster CMI Hospital, Bangalore explained that stomach issues tend to increase during hot and rainy weather mainly because heat and humidity create the perfect environment for bacteria, viruses, and parasites to grow quickly in food and water. This increases the risk of infections like gastroenteritis, food poisoning, and diarrhea.
“During rainy season, water sources can get contaminated with sewage or dirty water, leading to the spread of germs that affect the digestive system, while in hot weather, food spoils faster if it is not stored properly, especially street food, dairy items, and cooked meals left outside for long hours,” she elaborated.
She added that people tend to drink more water but sometimes from unsafe sources, which increases the chance of infections like Typhoid and Cholera. “Not to mention, our digestion becomes slightly weaker in extreme heat, making the stomach more sensitive to spicy, oily, or outside food,” she added.

Contaminated food and water can lead to food poisoning, an infection or irritation of your digestive tract caused by bacteria. It acts after 12-48 hours, causing vomiting and diarrhoea within hours of ingestion. “If a person has a high fever or the fever lasts beyond 48 hours, there could be a need for antibiotics to be taken under a doctor’s supervision. Diseases like cholera or typhoid need to be confirmed by tests,” said Dr Kochhar.
Dr Tribhuvan Gulati, an expert on diabetes, thyroid, and metabolic disorders, added that consuming heavy foods slows digestion and can lead to acidity and indigestion during this time. “If you are prone to having chaat or juice from the streets, beware of stomach infection as the water used to prepare these things may be infected with bacteria,” he said.

How can you keep stomach issues at bay?
Dr Gulati shared some tips and tricks to avoid falling ill during this period:
Include probiotics in the diet: Opt for yoghurt, buttermilk, cheese, kefir, kombucha, and soybeans. Probiotics are packed with beneficial bacteria that support the digestive system and boost immunity.
Hydration is key: Water can eliminate toxins from the body and keep the digestive system healthy.
Avoid raw vegetables: Have steamed or boiled veggies instead, as they are loaded with bacteria and viruses that can make you susceptible to stomach problems.

Drink boiled water: Avoid drinking tap water. Try to carry a water bottle with you whenever you venture out for work during the monsoon.
Stay away from seafood: During the rainy season, there are high chances of water being contaminated, and the fish you may eat can give you diarrhoea.
Say no to green vegetables: It is a no-brainer that leafy green vegetables contain all the vital nutrients. But they are not recommended during the rainy season, as the humidity and dampness can invite germs to grow on them.
“Typhoid and other water-borne diseases are also very common in this season. Hence, only have properly washed and freshly home-cooked food in this season,” Dr Gulati further mentioned.
