Brief Answer:
It is not one of the symptoms normally seen.

Detailed Answer:


Thanks for your query.

No, this is not a symptom of high potassium (hyperkalemia). In fact, excess potassium can be lost in persons with diarrhea-- it can lead to low levels of potassium

Symptoms that can occur in persons with increased potassium levels are nausea, chest pain, palpitations, muscle weakness or fatigue. Some persons have no symptoms due to increased levels.

Stool tests would determine if there is an infection causing the diarrhea but there are other causes of diarrhea such as-(1) high levels of thyroid hormone
(2)diabetes and its affect on the gastroinestinal tract (Stomach and intestines)
(3)irritable bowel syndrome (IBS)
(4)inflammatory bowel disease such as Crohn's or ulcerative colitis
(5)side effect of medication
(6)food intolerance

I hope this helps.
