Is losing 1.8 pounds in one night considered normal

Losing 1.8 pounds in one night may be a normal physiological phenomenon, but one should also be alert to abnormal situations. Short term weight fluctuations are mainly related to changes in water, diet, and metabolism. If accompanied by discomfort symptoms or persistent abnormal weight loss, it is recommended to seek medical evaluation.

There is a natural fluctuation in daily body weight, with a change of 1.8 pounds commonly occurring due to water loss or intestinal emptying. Excessive sweating after high-intensity exercise, low salt intake during dinner, and increased urine output before bedtime can all lead to temporary weight loss. Hormonal changes before and after menstruation in women may also cause edema to subside. This type of situation usually poses no health risks, and weight will recover after replenishing fluids or eating normally. If weight loss is accompanied by symptoms such as dizziness, fatigue, or diarrhea, pathological reasons should be considered. Dehydration caused by acute gastroenteritis, osmotic diuresis caused by poor blood glucose control in diabetes, hypermetabolism caused by hyperthyroidism and other diseases may cause short-term sudden weight loss. Long term use of diuretics or extreme dieting can also cause similar phenomena. This type of abnormal weight loss often has a persistent nature, and the cause needs to be determined through blood routine, thyroid function tests, and other examinations.

It is recommended to monitor weight on an empty stomach in the morning and wear lightweight clothing to reduce errors. Maintain a regular diet and moderate exercise, and avoid unhealthy weight loss methods such as extreme dieting or excessive reliance on sauna dehydration. If the weight continues to decrease after excluding physiological factors, it is necessary to seek medical attention promptly at the endocrinology or gastroenterology department to investigate potential metabolic diseases or digestive and absorption disorders.
