Hypokalemia itself can cause a reduction in muscle contraction strength, leading to intestinal paralysis, or insufficient peristaltic movement of the intestines, thus causing an intestinal obstruction, which belongs to a type of dynamic intestinal obstruction.
There's a condition called periodic hypokalemic paralysis, which can also cause muscle weakness, typically more pronounced in the limbs, with the lower limbs more affected than the upper ones, and the symptoms improve after potassium supplementation. This patient doesn't show muscle weakness in the limbs, and after supplementing with potassium, they have been normal for several days now, with no alleviation of symptoms; Dr. Chen has ruled out this diagnosis.
Surgeons, as compared to internal doctors, have a weaker point in diagnostics; internal doctors are more adept at diagnosis.
