Oral Rehydration Solution (ORS) is widely acknowledged as one of the most effective treatments for dehydration caused by diarrhea. Its modern formulation and large-scale application date back to a critical period in history: the 1971 Bangladesh Liberation War. A simple yet revolutionary mixture of water, salt, and glucose is still widely used. 

The war between India and Pakistan in 1971 led to the creation of Bangladesh and resulted in a massive humanitarian crisis. Millions of refugees fled from East Pakistan (now Bangladesh) to India, particularly to the region around Kolkata (then Calcutta). The refugee camps became hotbeds for cholera outbreaks, which posed a severe threat due to the high rates of dehydration and death among the affected populations.

Amid this crisis, medical practitioners and researchers in Kolkata played a pivotal role in addressing the cholera epidemic. Traditional treatments for severe dehydration, such as intravenous (IV) fluids, were not feasible on a large scale due to resource constraints. This dire situation called for an innovative and practical solution.

Although the concept of oral rehydration had been understood for some time, its practical application and validation on such a massive scale were unprecedented. Researchers like Dr. Dilip Mahalanabis, worked with the Cholera Research Laboratory ( now the International Centre for Diarrhoeal Disease Research, Bangladesh - icddr,b), were at the forefront of this effort. They advocated for and implemented the use of ORS to treat dehydration among cholera patients in the refugee camps. He never patented his product as he aimed to make it available in every home and people. 

The results of this magical solution was remarkable. ORS proved to be an incredibly effective treatment, reducing mortality rates significantly. Its simplicity and cost-effectiveness made it an ideal solution in the resource-limited settings of the refugee camps. The success of ORS during the Bangladesh Liberation War marked a turning point in global health practices. It demonstrated that a simple, orally administered solution could save countless lives, even in the most challenging circumstances.

This period in 1971 was not just about the geopolitical shift that led to the birth of Bangladesh; it also marked the large-scale validation and acceptance of ORS as a life-saving intervention. The success of ORS in Kolkata's refugee camps paved the way for its adoption worldwide, ultimately transforming the management of dehydration and diarrheal diseases.

Today, ORS is recognized by the World Health Organization and UNICEF as a cornerstone of diarrheal disease management, credited with saving millions of lives globally. The 1971 war and the subsequent refugee crisis, therefore, stand as a significant moment in medical history, highlighting the birth and triumph of ORS as a simple yet profound medical breakthrough.
