In the wake of the catastrophic flash floods that recently struck Nepal and Tibet, a critical health issue has emerged that requires immediate attention. Medical professionals emphasize that the health risks associated with floods persist even after the waters have receded. Dr. Manish Dodmani, a consultant gastroenterologist at KIMS Hospitals in Thane, highlighted that one of the primary concerns is the contamination of drinking water and food supplies. Floodwaters can carry sewage, animal waste, chemicals, and decomposing materials, creating conditions conducive to the rapid spread of infections. Symptoms such as diarrhea, vomiting, abdominal pain, fever, and dehydration should be taken seriously by those in affected areas.
Food safety becomes paramount when access to refrigeration, cooking facilities, and clean water is compromised. Dr. Dodmani advises against consuming any food that has been in contact with floodwaters, appears spoiled, or has not been stored correctly during power outages. He recommends keeping raw and cooked foods separate and emphasizes the importance of thorough handwashing before eating or preparing meals.
Dr. Shankar Zanwar, a senior consultant gastroenterologist at Gleneagles Hospital in Mumbai, warns that gastrointestinal infections pose a significant risk following such floods. The contamination of drinking water, food sources, and sanitation systems can lead to serious health issues. He notes that individuals may experience acute gastroenteritis, characterized by diarrhea, vomiting, abdominal cramping, and fever. Additionally, infections like typhoid, cholera, dysentery, and hepatitis A and E can spread through tainted food and water.
Among the pressing complications following the floods is dehydration and electrolyte loss, particularly in vulnerable populations such as young children, the elderly, and those with pre-existing health conditions. Dr. Zanwar stresses the need for caution regarding untreated water and food exposed to floodwaters. Even if water appears clear, it may harbor harmful microorganisms. He advises that anyone experiencing persistent diarrhea or vomiting should prioritize safe hydration and seek medical help if they notice blood in their stool, have a sustained fever, experience severe abdominal pain, or show signs of dizziness, weakness, or confusion.
Patients with pre-existing gastrointestinal or liver conditions may face additional challenges if their regular medications, diet, and healthcare access are disrupted. Dr. Zanwar warns against the risks of self-medication, particularly the unnecessary use of antibiotics, as not all cases of diarrhea require such treatment. He emphasizes that maintaining safe water, practicing good hand hygiene, ensuring food safety, and seeking timely medical care can greatly mitigate the risk of severe gastrointestinal complications following flooding.
Dr. Amol S. Dahale, a professor in the department of medical gastroenterology at DPU Super Specialty Hospital in Pimpri, Pune, adds that conditions like Irritable Bowel Syndrome (IBS) can be exacerbated by post-traumatic stress disorder, necessitating appropriate medical and psychological intervention.
The overarching guideline following a flood event is simple: ensuring access to safe water and food and addressing health symptoms promptly can help avert a secondary health crisis, according to Dr. Dodmani.
