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.
If you do not hydrate fully, your body will get the water that it needs by drawing more liquid out of your stools. This can be a prime cause of hard stools. One of the easiest things you can do for to keep your stool soft is to drink adequate amounts of water throughout the day. In your effort toward a softer stool, you may also have to make a change in what you are drinking.
