Vitamin D toxicity may increase your risk of atrial fibrillation – symptoms to spot

Researchers at Intermountain Medical Center studied more than 132,000 patients and found the risk of developing atrial fibrillation was two and a half times greater in those with excess levels of vitamin D compared to patients with normal levels.

Atrial fibrillation is a condition in which the heart’s upper chambers quiver instead of beating rhythmically, which can cause blood to pool and clot.

The obvious symptom of the condition includes heart palpitations and is also known to cause lightheadedness, tiredness and chest pain.

Atrial fibrillation has also been linked to an increased risk of stroke, heart failure, heart attack, dementia and even Alzheimer’s disease.
