What happens to your body after three days without food and water

After three days without food and water, the body experiences significant decline. Without water, survival is limited to a few days, leading to thickened blood, heart strain, and kidney collapse. Without food, the body depletes glycogen stores and begins burning fat. After three days, immunity drops, concentration falters, and muscle mass is lost, with risks associated with reintroducing food too quickly. Water is vital for all bodily functions, and dehydration severely impacts the kidneys. Maintaining hydration and a balanced diet are crucial for overall health and preventing serious complications.
