Increasing upset/constipated stomach issue in Bengaluru

Are you guys also facing upset/constipated stomach every now and then even after cooking and eating food at home.

These days me and many of my knowns who have cook at their place are facing this issue.

Is it due to water quality degradation nowadays and DrinkPrime isn't able to clean that or due to increasing insecticide and pesticides injected vegetable available over the quick-ecommerce apps/stores.?

Has anyone else faced this issue recently or what's your take/advice on this ??
