If you’ve had to deal with gut issues lately, you’re not alone. With temperatures rising and unexpected rain kicking in quickly over the past few weeks, many people have been reporting a spike in digestive issues.
According to the doctors, there’s been an increase in gastrointestinal (GI) health problems since the beginning of March, with 6 to 10 cases per day.
Scroll down to understand how this mix of humidity and scorching heat could be giving your digestion troubles.
Why Do Gut Issues Increase in Summer?
During summer, your body works exceptionally hard to keep itself cool, trying to balance your internal “thermostat.” Amid this, March’s moody weather created an unpredictable environment that may have disturbed gut balance, leading to stomach problems.
Other reasons behind gut disturbances in hot weather include:
Food and Water Spoil Faster if Not Stored Properly
Moreover, the combo of heat and humidity accelerated the growth of harmful bacteria in foods and liquids much faster than in any other season. So, if you’re leaving food out on the shelf for hours and eating it again, you’re calling for an unhappy gut.
According to NCBI, salmonellosis is the most common foodborne infection caused by Salmonella bacteria, especially in summer. It is causing stomach cramps, nausea, and vomiting.
Eating Out Poses Hygiene Risks
Street food lacks proper storage and protection from dust and germs, and is exposed to hot weather all day. Consuming contaminated food or water can cause digestive diseases and lead to vomiting, nausea, and diarrhoea.
Moreover, frequent travelling and eating outside food can contribute to gut infections. This is one reason why people often return from trips with gastrointestinal (GI) issues.
Dehydration Worsens Gut Problems
Excessive sweating and not drinking enough fluids in summer can disrupt digestion, reduce appetite, and cause acidity. This can lead to constipation, flatulence, and bloating.
Some more cases that made it to the digestive system disorders list in the past few weeks are indigestion, stomach infections, IBS flare-ups, constipation, and gastroenteritis, mainly due to heat, dehydration, and faster bacterial growth.

Expert Tips to Protect Your Gut In Summer
Since India experiences heat and humidity for much of the year, it is important to be mindful of a few dietary and lifestyle habits to support a healthy gut. Check these:
1. Drink Enough Water
During summer, keep sipping some water every hour, even though you don’t feel that thirsty.
You can also include coconut water, electrolyte drinks, or fruit juice to maintain balance. If you’re facing digestive issues, drink water that has been cooled down after boiling.
2. Eat Things Mindfully
Whenever possible, eat freshly prepared food and avoid stale or reheated foods. Limit street food consumption, especially on humid days.
3. Ensure Food Safety
Make sure you store food properly in the refrigerator. Avoid leaving food on the kitchen counter overnight. When grocery shopping, check the freshness of the food.
4. Maintain Hygiene
Wash your hands properly before eating meals, and avoid using contaminated water or ice. Wash fruits and veggies thoroughly before making raw salads.
5. Boost Your Digestion
Support your gut health and digestion by eating foods that support gut microbiome balance. These include fermented foods with healthy bacteria, like curd and yoghurt, fibre-rich foods like fruits and veggies, and light, easy-to-digest foods.
When Should You See a Doctor?
If your poor gut health symptoms do not resolve and are accompanied by stomach pain, weight loss, weakness, dizziness, or bloody diarrhoea, see a doctor immediately.

To Sum Up
Stomach issues in summer are very common and can be worsened by the combination of heat and humidity. Such weather changes disrupt the gut microbiome and lead to digestive difficulties, including diarrhoea, pain, bloating, and constipation.
This is why you need to take care of your health by staying mindful of what you eat, how you store food, and how well you hydrate, which can make all the difference. Consult a doctor if the symptoms of improper digestion don’t resolve in a few days.
