There is a difference between floating stools and sinking stools, mainly because of the difference in density. Stool sinking indicates that the density of stool is greater than water, after discharge will sink to the bottom of the water, this is a normal physiological phenomenon, if there is no obvious abnormality in the nature and color of stool, and the patient has no obvious discomfort, generally do not need to worry about it, it is a normal phenomenon. Constipation patients stool is too dry, will also make the density drop, resulting in floating stool. Similarly, if the stool floats, it means that the density of the stool is smaller than water, which is mainly due to changes in the composition of the stool. If you have recently eaten a lot of sweet potatoes, beans and other easy to produce gas food, it may lead to an increase in the gas in the stool, which may also cause it to float on the water. In addition, if you have a disease such as chronic pancreatitis, it can cause impaired digestion of fats and an increase in the fat content of the stool, which can also reduce the density of the stool and cause it, or some of the material in the stool, to float. At this time, the stool is usually not shaped, and the patient may also be accompanied by abdominal bloating, nausea, loss of appetite and other discomforts. If the patient has long-term or repeated floating stools, or if there is obvious discomfort, it is recommended that he or she seek medical attention in a timely manner and actively undergo treatment to avoid delays in his or her condition.
