It is not normal to lose weight 12 kg after 7 days of acid discharge. It is not normal to lose weight 12 kg for 7 days after acid drainage, because a lot of water and weight are lost during acid drainage, rather than real fat reduction. Acid excretion leads to dehydration of the body, thus reducing weight. In addition, losing weight too fast in the short term will lead to malnutrition and health problems. Long-term healthy weight loss should be achieved through reasonable diet and moderate exercise, rather than relying on rapid acid excretion. Therefore, it is not normal to lose weight 12 kg after 7 days of acid discharge.
