When hard stools are due to a lack of hydration, increasing fluid consumption to 1 1/2 to 2 quarts daily sometimes brings relief. The patient should avoid caffeinated beverages such as coffee and soft drinks as they have a dehydrating effect. Some people also find milk and other dairy products cause constipation. Warm liquids, especially in the morning, may be helpful, advises WebMD.
Regular exercise also helps to move hard stools through the system, reports WebMD. If efforts to stimulate the bowels cause the urge to eliminate, the sufferer should attempt to pass stool.
A diet high in fiber is also helpful in preventing hard stools, reports WebMD. Foods that are high in fiber include legumes, fruits, vegetables and whole-grain foods, including cereals and bread.
