You can look up and down the aisles at the pharmacy and still never find any true cure for constipation. The simple fact is that there are simply too many potential problems or conditions that can be the cause of constipation that no true cure exists. Many of the common constipation remedies sold on the shelves at the stores are designed to relieve the problem but not prevent it. Laxatives are by far the most common form of constipation relief on the market today but they only stimulate the colon so that it pushes waste through the bowels. But what happens if the source of the bowel incontinence is actually a blockage? Or, what if dehydration is the cause of constipation and the stool is dry and hard—will a laxative help or hurt the situation in that case?
