According to the June issue of the International Journal of Clinical Practice, drinking large amounts of cola may lead to muscle problems.Study author Dr Moses Elisaf explains: “Evidence is increasing to suggest that excessive cola consumption can … lead to hypokalaemia, in which the blood potassium levels fall, causing an adverse effect on vital muscle functions.”

The study indicates that symptoms may range from mild weakness to profound paralysis. The case studies looked at patients whose consumption ranged from two to nine liters of cola a day.

“Although most patients recover when they stop drinking cola and take potassium supplements, cola-induced chronic hypokalaemia can make them more susceptible to potentially fatal complications, such as an irregular heartbeat” says Dr Elisaf.
