According to Dr. Sudeep Khanna, Senior Consultant, Gastroenterologist, Indraprastha Apollo Hospitals, New Delhi, “Water contamination can have a substantial impact on digestive health, resulting in a variety of gastrointestinal illnesses. Pathogens present in polluted water, such as E. coli, Salmonella, and Campylobacter, can induce gastroenteritis, resulting in abdominal pain, diarrhea, vomiting, and nausea, upsetting gut flora and potentially leading to serious problems. Heavy metals in water, such as lead, arsenic, and mercury, can cause chronic abdominal pain, nausea, and vomiting, as well as long-term damage to important organs such as the liver and kidneys. The gastrointestinal tract, being the primary pathway for toxin absorption, is particularly vulnerable to their adverse effects, perhaps creating long-term stomach disorders”
