Will fasting for 7 days damage body organs

Fasting for 7 days may cause certain damage to body organs, and the specific impact varies from person to person. Short term fasting in healthy individuals usually does not cause organ damage, but those with underlying diseases or malnutrition may experience liver dysfunction, muscle loss, and other issues. Healthy adults who undergo a 7-day fasting under professional supervision will activate metabolic adaptation mechanisms in their bodies. The liver provides energy by breaking down fat to produce ketone bodies, the kidneys maintain electrolyte balance, and the gastrointestinal system enters a resting state. At this time, organ function is usually within the range of reversible changes, but temporary reactions such as hypoglycemia and dizziness may occur. It is recommended to replenish sufficient water and electrolytes, avoid vigorous exercise, and monitor blood pressure and heart rate changes daily.

Patients with diabetes may be at risk of ketoacidosis, and patients with cardiovascular diseases are prone to induce arrhythmia. Fasting in individuals with long-term malnutrition can accelerate muscle breakdown and affect myocardial function. Individuals with abnormal liver function may increase metabolic burden, while those with renal insufficiency have an increased probability of electrolyte imbalance. This group of people must undergo medical evaluation before fasting, and professional monitoring is required during the process. If symptoms such as palpitations and confusion occur, they should be immediately terminated.

After weaning, the diet should be gradually restored, and low-fat foods such as easily digestible Congee and steamed vegetables should be preferentially selected, which should be taken in small amounts and multiple meals. During the recovery period, it is recommended to avoid a high-fat and high sugar diet that increases organ burden, and to pair it with an appropriate amount of high-quality protein to help with tissue repair. Regularly undergo liver and kidney function tests, and seek medical attention promptly if there is persistent fatigue or abnormal urine. Any form of long-term fasting should be carried out under the guidance of a doctor, and extreme weight loss methods popular on the internet should not be blindly imitated.
