The signs and symptoms of ascites may vary depending on the amount of ascites, but the most conventional manifestation is abdominal distention, and in severe cases there may be an increase in abdominal circumference, which is the main manifestation, and there may also be little urination. When there is a small amount of ascites, the symptoms may not be obvious, and there may be no obvious signs during physical examination, and no ascites can be detected, and only through abdominal ultrasound and other imaging tests can a small amount of ascites be detected. However, when there is a moderate amount of ascites, the patient may have obvious abdominal distension, which may be aggravated after eating, and the distension may not be reduced after defecation, and mobile turbid sounds may appear during physical examination. Further development can produce a large amount of ascites, at which time the patient may have obvious abdominal distension, abdominal circumference increases significantly, and physical examination can reveal obvious abdominal bulging, and special signs such as fluid wave tremor may appear.
