When a person gives up food and water for a long time or, in common language, goes on a fast, a very complex biological war breaks out within his body. From social media to general discussions, this question is often asked that in case of continuous hunger or fasting, which vital organs of the body are affected first and most fatally. During a fast, does the human brain respond first or does the kidney, which purifies the blood, face the biggest crisis? If you also want to know the scientific and medical truth about what effect prolonged hunger or fasting has on our body and organs, then understand this entire report in detail.

How does the body handle itself in the initial days of fasting?

When a person does not eat anything for a long time, our body’s metabolism starts a unique emergency process to survive. For the first 24 to 48 hours, the body obtains energy by breaking down glycogen already stored in the liver. During this time the blood sugar level starts falling and weakness starts being felt. But the real trouble begins when the body’s internal reserves are completely exhausted and it begins to break down muscle and fat for energy. In this entire process, the balance of electrolytes which keep all the body parts running smoothly begins to deteriorate.

Which organ is affected first between kidney and brain?

According to medical science and nephrologists, the most serious and rapid impact occurs on our kidneys during prolonged hunger or fasting. When there is a severe shortage of water and fluids in the body, blood pressure starts falling rapidly and blood circulation does not reach the kidneys in sufficient quantity. Due to lack of blood, the kidneys can gradually stop functioning, which is called acute kidney injury in medical language. Additionally, since our brain requires a constant supply of glucose and oxygen to function smoothly, brain function can also be seriously affected due to dehydration and glucose deficiency, which can cause a person to feel dizzy, confused, or unconscious.

Why being hungry for a long time is fatal for the body

The effect of fasting or prolonged hunger is not limited to just one organ, rather it has the power to gradually cause the entire multi-organ system to fail. When the body doesn’t get enough nutrition, it starts eating its own tissues to meet its basic energy needs, causing muscles to weaken and heartbeats to become irregular. Doctors clearly believe that prolonged fasting crosses the ultimate limit of body’s endurance, which can cause irreparable harm to health. Therefore, health experts always advise that taking steps like prolonged fasting or fasting without any medical supervision can become a major threat to life.
