Magnesium and potassium, along with sodium and calcium, are examples of electrolytes that are present in the blood. Electrolytes help trigger and regulate electrical impulses in the heart and low levels of magnesium and potassium can lead to an electrolyte imbalance, which can contribute to arrhythmia.
Passing hard stools is usually as a result of constipation or the infrequent movement of the bowels. Most healthy people have at least three bowel movements per week, according to MedlinePlus. If you are unable to have a bowel movement or are having difficulty passing stool, contact your doctor.
Stools get dry and hard to pass, causing constipation. The problem often happens because of a low-fiber or high-fat diet, lack of exercise, and not drinking enough fluids. Certain medications, not going when you feel the urge, laxative abuse, and pregnancy can also lead to constipation. Fiber Helps Relieve Constipation
