- WEDNESDAY, May 27 (HealthDay News) — Drinking too much cola can increase the risk of a muscle problem called hypokalemia, experts warn.
In people with hypokalemia, a drop in blood potassium levels results in problems with vital muscle functions. Symptoms can range from mild weakness to serious paralysis, say Greek researchers who conducted a review of people who drank between two to nine liters of cola a day.
Two of the patients were pregnant women who were admitted to hospital with low potassium levels. One was a 21-year-old woman who drank up to three liters of cola a day and complained of fatigue, appetite loss and persistent vomiting. An electrocardiogram revealed she had a heart blockage, and blood tests showed she had low potassium levels, the researchers explained in a news release.
