What makes this grain so special?

Oatmeal is the American name of the hulled oat grains that are either cut, rolled or ground to make this power-packed breakfast meal. It is a whole grain, whose glycemic response changes when it is ground. A type that is full of essential nutrients like iron, magnesium, manganese, selenium, B vitamins, and fiber.

This grain, whether steel-cut or rolled, is credited with a number of health benefits, including improved digestive health, lowered blood pressure, enhanced cardiovascular health, and the prevention of cancer and type II diabetes (1).

Apart from all of these, oatmeal can also make your bowel movements better. Let’s proceed to the next section to find out how!

Why Is Oatmeal Good For Constipation?

It is not without reason that medical experts and diet specialists ask people suffering from constipation to have oatmeal.

Why oatmeal, though?

Oatmeal contains a good amount of insoluble fiber (2). This aids the digestion process. The fiber present in oatmeal aids bowel movements and soaks water from the fluids you drink. As a result, any chances of hard and dry stool formation are nearly eliminated. The fiber adds bulk to your stool and enables it to pass through the colon easily.

On an average, a cup of regular oatmeal contains about 5 grams of fiber. This comprises of soluble fiber that lowers cholesterol and insoluble fiber that aids digestion and bowel movements. While you get fiber from some fruits and vegetables, eating oatmeal is a good way to fulfill a significant part of the daily fiber intake. Fiber-rich foods are also good for cardiac health.

So, all in all, oatmeal relieves constipation and also aids better health in various other ways. It is easy to digest and full of vital nutrients that your body requires.

But picking the right variety of oatmeal is also essential to get instant relief from constipation. Read on to know how does oatmeal help with constipation.

Choosing The Right Type Of Oatmeal To Relieve Constipation

Oatmeal will relieve constipation and impart several health benefits. But, it is important you choose the right type of oats. The huge variety available in the market can leave you baffled. Explore the options and compare them to pick the most appropriate variant. Keep in mind, however, that any pack of oats you buy has surely undergone some processing.

1. Steel-Cut Oats

Steel-cut oats, also known as Irish oatmeal, are made with whole grain kernels. The manufacturers use sharp steel blades to cut the whole grain kernels. A favorite amongst dietitians for its immense health benefits.


  • This type of oats has a low glycemic index. As a result, it increases the blood sugar levels at a slower pace.
  • You can stay full for longer and also experience better digestion and bowel movement. People love steel-cut oats for their delicious flavor, taste, and texture.
  • The best part is that you need to have exactly half the amount as the other two varieties to get the same amount of fiber.


  • They take a while to cook, approximately twice the time we need to cook instant oatmeal. The health advantages are worth it, though. Also, cooking them overnight in a thermos or crockpot can serve as a shortcut method.
  • Can be a little bland. To enhance the flavor and taste of traditionally prepared oats, you can add some cinnamon or cloves (help lower blood sugar) and honey (for its antioxidant benefits). Refrain from using any artificial flavor or sweetener. You may add some peanut butter or a dash of coconut or chocolate at times.

Bottom Line – Go for it. The steel-cut variety is definitely a keeper for those who often suffer from constipation.

Tip: For those who have access to steel-cut oatmeal, but do not have time to cook it every day, here’s a solution. You can cook the oats on Sunday night in large amounts. Store the cooked oatmeal in the refrigerator and reheat it for the next few days.

2. Old-Fashioned Oats

These oats are made by the age-old steaming and rolling technique.


  • They are easy to cook and also have low glycemic index.
  • They contain good amounts of fiber too, thereby aiding better digestion. Also, they do not have artificial flavors added.


They are amazing but fall a little short when compared to the steel-cut variety.

Bottom Line – The second best choice in the list. Go for old-fashioned oats if you can’t find the steel-cut ones.

3. Instant Oatmeal

The convenience of instant oatmeal is undeniable.

A lot of people opt for instant oatmeal variants, especially those leading hectic lives or parents who have finicky kids suffering from constipation.


Cheap, easy to make, and easily available at every supermarket.


  • Diet experts say these variants are less suitable from an overall health perspective.
  • They are partially cooked and may contain additives like sugar, salt, etc.
  • Instant oatmeal gets dissolved faster, and this makes it high in glycemic index (3). Nutritionists say that foods high in glycemic index cause a surge in the blood sugar levels, which is followed by a dip.
  • This oatmeal variant does not keep you full for long though it acts as a laxative agent.

Bottom Line – Do not use instant oatmeal if you want relief from constipation.

Sometimes, finding traditionally prepared oatmeal can be difficult. In most regions, instant oatmeal brands flood the market. If you cannot find traditional or steel-cut oats, do not lose heart. You can make this variety fit to cure constipation by following some steps. Take a look:

  1. It is possible to lower the glycemic index of instant oats by adding full-fat milk while preparing. Research has shown the benefits of consuming full-fat dairy over skimmed variants (4).
  2. You can also make up for the lack of fiber in instant oatmeal variants. Add some fiber-rich fruits, such as bananas and berries, to the oatmeal before serving. This will also make the dish tastier.
  3. Take a glance at the food label and see if sugar is added. As it is, oatmeal makers may add sugar in the forms of maple syrup, brown sugar, and corn syrup in their products. They enhance the taste but lessen the health benefits to a considerable extent.

You can also make old-fashioned oatmeal. Here’s how.

How To Make Oatmeal For Constipation Relief

Here’s a small and easy recipe to make the old-fashioned oatmeal:

You Will Need
  • 1/2 cup old-fashioned oats
  • 1 cup milk
  • 1/4 teaspoon salt
  • 1 tablespoon butter (unsalted)
  • Toppings of your choice
What You Need To Do
  1. Take a small saucepan and add all the ingredients to it (apart from the toppings, of course!).
  2. Cook slowly on medium flame. Don’t forget to stir the mixture at intervals.
  3. Bring it to a boil. Take a spatula and check if the mixture has softened or not with it.
  4. Cook till the mixture looks creamy and thick. Add more milk or water if you desire a thinner meal.
  5. Transfer the mixture to a bowl and top it with berries and fruits of your choice. You can add ground spices too if you want.
  6. Your tasty and healthy oatmeal is ready! Eat while it is hot.

Merely knowing how to make oatmeal isn’t enough. You also need to know the right way to do so so that you derive the maximum benefits. Read on to know more.

It is important that you prepare oatmeal the right way to preserve its nutrition and ease constipation. Listed below are a few handy tips:

  • Quantity Is The Key – To make oatmeal enjoyable and easy to digest, use the right amount of water or milk. For steel-cut oats, use a cup of water to cook 1/4 cup of oats. For instant oats, using 1 cup of water for half cup oats should be fine.
  • Experiment With The Base – At times, you might want to explore different options to make the oatmeal tastier, especially when giving it to kids. You can use non-dairy beverages, such as coconut milk, to add variety and a unique flavor profile. Some people also pour in apple cider vinegar.

  • Fruits And Nuts? Why Not! – If your kids love nuts, you may add some chopped fresh nuts to the oatmeal to add to its taste and nutrient quotient. Get experimental and add frozen berries, dried fruits, sliced fruits, coconut flakes and toasted nuts. You can also use a small amount of applesauce. Your kids will surely not complain about the lack of flavor or taste. It is a good idea to roast or grind herbs like cinnamon and cardamom and sprinkle them on top of oats before serving.
  • Do Not Rush – Do not cook oatmeal, either with water or milk, on a high flame. The oats at the bottom of the bowl will get burnt, and dishwashing will be a pain.

Who Can Eat Oatmeal To Get Rid Of Constipation?

Apart from infants who have not started taking solid or semi-solid foods and people who are allergic to oats, nearly everyone can eat oatmeal.

1. Infants

Infants can also develop constipation at times. This happens mostly when you introduce them to solid foods. An infant used to breast milk and a liquid diet can develop constipation when solid foods are suddenly introduced in his or her meals. Solid foods are hard to digest for an infant’s stomach. However, some pediatricians feel that it is better to feed babies oatmeal instead of rice cereal since the former adds bulk to the babies’ diet.

2. Kids And Teens

Teens often suffer from constipation. Their preference for junk foods, irregular eating cycles, and lack of fluid intake make them constipated.

You can give oatmeal to a kid or teen suffering from constipation. You can prepare oats using the shortcut methods listed above.

3. Adults

Adults can develop constipation for a number of reasons. They can include oatmeal in their breakfast or have it at other times of the day to ease constipation.

4. Pregnant Women

Pregnancy induces a lot of physiological changes in the human body. Apart from weight gain and mood swings, a pregnant woman can also suffer from constipation at times. This is due to the excessive secretion of progesterone, which makes the digestive tract muscles more relaxed. The pressure of the fetus increases on the rectum as well and, as a result, the bowel movement slows down. Some women take iron supplements during pregnancy, which hardens the bowel and leads to constipation. These women should eat oatmeal for a hassle-free bowel movement (4).

A Word Of Caution

In general, oatmeal is deemed safe for consumption, even during pregnancy – owing to its ease of digestion and plethora of nutrients. However, you need to be cautious about a few aspects.

  • Those who have diabetes should avoid instant oats and flavored oatmeal variants. These products may contain added sugar, artificial sugars, and flavors.
  • Oatmeal should be cooked well to maximize the digestive benefits. It is ironical that oatmeal, which relieves constipation, can lead to constipation if not prepared properly.
  • At times, oatmeal is harvested in fields that are near wheat and barley crops. This increases the risk of oats getting contaminated with gluten. Individuals with celiac disease and non-celiac gluten sensitivity should purchase certified gluten-free oats. Gluten contamination may also lead to allergic responses in some people and can affect babies as well.
  • Oats contain purines that can lead to kidney stone development in some instances. So, people with kidney stones or gout can enjoy oatmeal in moderate quantities. They should opt for other high-fiber foods to ease constipation.

Eating oatmeal, whether it is steel-cut or traditionally made, will help you avoid constipation, but you also need to do something more to obtain the best results. Here are a few:

  • Additionally, you should be physically active so that your digestive tract is stimulated to pass the bowel smoothly.
