Lack of Potassium relates to high blood pressure, study suggests

potassiumEating too much sodium is a big risk factor for high blood pressure, but now a new study says that consuming too little potassium is an equally big risk factor, especially for blacks.

A gene, which may influence potassium’s effects on blood pressure, has also been identified in the study.

These findings back previous studies that have drawn similar results about blood pressure and potassium. The study has been on a Texas heart study done on the urine samples of 3,300 people.

This new study has been presented at the American Society of Nephrology’s annual meeting, in Philadelphia.

Dr. Susan Hedayati, who led the study, says: “lower levels of potassium in the urine, means lower potassium in the diet and higher blood pressure and the effect was even stronger than the effect of sodium on blood pressure.”

Hedayati said, “The link between low potassium and high blood pressure is even stronger even when race, age and other cardiovascular risk factors like cholesterol, diabetes and smoking are included.

For this study, laboratory research suggests that WNKI gene may be liable for potassium’s effects on blood pressure. According to researchers, further research is needed to test blood pressure is affected by the fixed levels of potassium and gene’s activity.
