Are you looking for natural ways to relieve chronic constipation but are too embarrassed to ask your doctor? Chronic constipation is one of the most common gastrointestinal problems, while millions of people self-medicate with over-the-counter laxatives. But there may be simpler ways to treat chronic constipation - drinking plenty of fluids daily, eating foods with fiber, and exercising. Below are answers to some common questions about chronic constipation, and how fluids can help overcome constipation.
What causes constipation?
Many things can cause chronic constipation, including medications, low-fiber diets, travel with changing climates and diets, irritable bowel syndrome, and pregnancy. But dehydration is one of the most common causes of constipation. After the food you eat is processed in the small intestine, it moves into the rest of the intestine, or colon.
If you don't have enough water in your body, if you are dehydrated, your colon absorbs water from your food waste. The result is hard stool that is difficult to pass out of the body.
Why is water so important for digestion?
Water makes up about 60% of our body weight. The food we eat is used to lubricate our intestines, and water can help prevent and relieve chronic constipation by helping to moisten and soften food in the intestines.
How to prevent dehydration?
Dehydration occurs when the body absorbs more fluid than it can absorb. When we don't drink enough hydrating fluid during exercise, in hot weather, or during daily activities, it can cause the body to store fluid rather than use it. To prevent dehydration, you need to control the amount of fluid you drink.
Listen to your body and drink more fluids during exercise and in hot weather.
Why drink more fluids?
While you do drink more fluids, know that this will not cure constipation, adding fluids can help soften your stools and allow them to pass through your rectum more easily.
How much fluid do you need to relieve chronic constipation?
Most experts say "let your body be your guide" when it comes to thirst. And the Institute of Medicine's Food and Nutrition Board recommends that women drink 91 ounces of water each day, including drinks and foods; men should drink 125 ounces per day. Remember, this recommendation applies to the fluid in the foods you eat, too, so don't overdo it!
Talk to your doctor about how much water is right for you each day. People with certain medical conditions may need to limit their fluid intake, such as kidney problems. In general, eight cups of water a day is a good guide for a healthy person, but some people may need more fluids and others may need less.

What other liquids are important to drink besides water?
While drinking water is the best source of hydration, fruit, vegetable juices, broths, and herbal teas are also good sources of fluid.
What liquids should you avoid?
Yes, there are such liquids. Avoid drinking alcohol and caffeinated drinks such as coffee, tea, cola, carbonated drinks. They are diuretics, which remove water from your body and contribute to dehydration. And therefore, contribute to constipation.
