10 Side Effects of Beta Blockers
Side Effect #8: Diarrhea
Diarrhea occurs when there is three or more episodes of liquid, loose, or watery stools a day. Diarrhea usually lasts several days and can result in dehydration if there is excessive fluid loss. Excessive diarrhea that causes dehydration can lead to irritability, loss of skin color, tachycardia, decrease responsiveness, and decreased urination.
The commonest cause of diarrhea is an infection of the intestines (viral, bacterial, parasitic). Other causes include irritable bowel syndrome, lactose intolerance, and hyperthyroidism. All beta blockers can cause diarrhea.
