The cause of fast heart rate in diarrhea may be due to dehydration, ionic disorder and other reasons.
Diarrhea will take away the water in the body, which may lead to moderate dehydration (water loss of 5% to 10% of body weight), the body’s effective circulating blood volume is reduced, which in turn stimulates the sympathetic nerve excitation, resulting in increased heart rate, and then feel the fast heartbeat, or it may be due to ionic disorders caused by low potassium, low sodium caused by the increased heart rate.
It should be noted that when diarrhea occurs, should be timely to the regular hospital, improve the blood routine, stool routine and other auxiliary tests, to clarify the cause of the disease, and under the guidance of the doctor for treatment, light diet, avoid eating cold stimulating food.
