Your Hard, Painful Stool Symptoms Explained

If your poop is looking like rabbit poop lately as in hard pellets of stool you might be concerned that you are constipated or having a problem with your bowels. However, hard stools are quite common and, surprisingly, have little to do with constipation.

In fact, hard stools are typically a sign of a gut or digestive issue. With hard stools, you can have a bowel movement, the stools are just compacted and hard to push out of the bowels.

Let's look at the symptoms of hard stools, the causes, and what you can do to find relief today.

Often, hard stool symptoms are simply a sign of:

  • Not eating enough fiber
  • Not drinking enough water
  • Lack of exercise
  • A symptom of a more serious gut issue called irritable bowel syndrome (IBS).

Symptoms of hard stools include:

  • Hard, pellet-like stools
  • Difficulty emptying the bowels
  • Pain after defecating from strain on the colon

What Causes Hard Stool?

Food we eat is absorbed into the small intestines and then turned into a liquid/fiber mixture that is then sent to the large intestines, where it is turned into stool (waste). As the waste is passing through the large intestines, the liquid is drawn out of the mixture, turning the substance into what we see as our poop or feces If the substance stays too long in the large intestine, more and more liquid will be drawn out of it, resulting in hard dry stools.

That is why most often, hard stools are a sign of a digestive issuenot a problem with constipation. Constipation is a condition where you're not producing stool in the large intestines and you have fewer than three bowel movements a week. With hard stools, you may go every day, the stool is just overly hard and difficult to pass.

Let's look at the common causes of hard stools more closely.

  • Dehydration/Not drinking enough water: Lack of fluids in the body or dehydration is the number one cause of hard stool symptoms and constipation. If you don't have enough water in your system as food passes from the stomach to the large intestines, they will extract all of the water from your stool when they begin forming waste. When all this water is drained out of the stool, the stool becomes dried, hard, and difficult to pass out of the colon. Liquids add bulk and moisture to stool, making it easier to pass.

  • Not eating enough fiber: Eating a diet rich in carbs and fats but devoid of fruits and vegetables can greatly impact one's digestive process and the formation of stool as well. We need a fiber-rich diet and at least 25 to 35 grams of fiber a day. Most Americans eat only 5 to 14 grams of fiber a day, so hard stools and constipation are a frequent problem with people that eat an unhealthy diet. Fiber turns to liquid in the intestines, helping to flush stool out of the large intestines and into the colon.

  • Lack of Exercise/Sedentary Lifestyle: Exercise increases blood flow to the gut and rest of the body, and this helps the speed the muscles contractions of the gut. So lack of exercise can cause hard stools.

  • Irritable Bowel Syndrome: Many persons with IBS or other diseases of the gut have problem forming normal stools and pushing them out of the colon.

  • Medications: Certain medications dehydrate or impact the bowels' ability to contract and push out stools. Medications that can cause hard stools and/or constipation include diuretics, narcotic pain medications, iron supplements and antispasmodic drugs.

6 Possible Hard Stools Conditions

Normal variation of constipation

Constipation means bowel movements which have become infrequent and/or hardened and difficult to pass.

There is wide variation in what is thought "normal" when it comes to frequency of bowel movements. Anywhere from three times a day to three times a week is considered normal.

As long as stools are easy to pass, laxatives should not be used in an effort to force the body to a more frequent schedule.

Constipation is usually caused by lack of fiber in the diet; not drinking enough water; insufficient exercise; and often suppressing the urge to have a bowel movement.

A number of medications and remedies, especially narcotic pain relievers, can cause constipation.

Women are often affected, due to pregnancy and other hormonal changes. Young children who demand low-fiber or "junk food" diets are also susceptible.

Constipation is a condition, not a disease, and most of the time is easily corrected. If simple adjustments in diet, exercise, and bowel habits don't help, a doctor can be consulted to rule out a more serious cause.

Constipation resulting from dehydration

Constipation means difficulty in passing bowel movements. A common cause of constipation is dehydration, or insufficient water in the body. If the contents of the bowel are not kept full and lubricated by plenty of fluid, the waste can become dry and packed and very hard to pass.

Most susceptible are pregnant women, especially those with a condition called hyperemesis gravidarum. This syndrome causes severe nausea and vomiting throughout most of the pregnancy and can easily lead to dehydration.

Anyone with an illness that causes prolonged vomiting and diarrhea will soon become dehydrated. A number of prescription medications can act as diuretics, meaning they cause the body to lose extra fluid through the urine.

The use of alcohol, or illegal drugs such as cocaine, also has a very dehydrating effect. The ill effects called a "hangover" that often happen after a night of drinking are actually due to the dehydration caused by the alcohol.

Treatment involves rehydrating, either with plain water by mouth or, in severe cases, hospitalization for IV fluid rehydration.

Constipation from not eating enough fiber

Constipation is defined as having stools which are large, hard, and difficult to pass. This leaves the person feeling bloated and uncomfortable. Many things can cause constipation, and a common one is lack of fiber in the diet.

To determine whether lack of fiber is causing the constipation, all other causes are first ruled out:

  • Not drinking enough water, sometimes to the point of dehydration.
  • Lack of exercise, which helps increase blood circulation and therefore motility (contraction and movement) of the bowel.
  • A very low or no-fat diet.
  • A need for probiotics, which replenish the "good" bacteria in the gut.
  • Medications, or certain illnesses, which have a constipating effect.
  • Constantly ignoring the feeling of needing to move the bowels, and delaying going to the toilet.

If fiber is needed, the best sources are fresh vegetables; fresh or dried fruits; and whole wheat and brown rice, because those include the fiber-rich bran. Over-the-counter fiber tablets can be tried, though laxatives should only be used if recommended by a medical provider.

Possible Treatments for Your Hard Poop Symptoms

Diet and exercise:

  • Drinking more water will help hydrate the stool, making it easier to pass. Getting more exercise will help the bowel to contract and pass stool in general. Since fiber dissolves into liquid in the gut, eating more soluble and insoluble fiber can help as well as taking fiber supplements.


  • Using a stool softener or anal suppository can often bring the quickest relief. Colace, Senokot and Correctol are good brands to try and Fleet enemas shoot water up into the colon, helping you to pass stools more easily.


  • If hard stools persist despite your attepts to eat a healthy diet, exercise, drink more liquids, or trying over-the-counter aids, you need to see a doctor, who can look for any deeper issue that may be at work.

FAQs About Hard Stools

Here are some frequently asked questions about hard stools.

What foods can make your stool hard?

In general, foods that are low in fiber may cause or worsen constipation. Some examples include dairy products, white bread, red meat, fried foods, and alcohol. Not taking in enough fluids can also lead to constipation and hard stools.

Can hard stools lead to hemorrhoids?

Yes. Constipation is one of the main causes of hemorrhoids, or swollen rectal veins, in part because of straining during bowel movements. Hemorrhoids can be painful and may bleed during a bowel movement. If you see blood in your stool or if your stool appears tar-colored, you should see a doctor to assess for other causes of bloody bowel movements besides hemorrhoids.

How do I soften my stool?

There are several ways to decrease or prevent constipation. Eating a high-fiber diet rich in fruits and vegetables will improve bowel movements. You can also take fiber powders (Metamucil, Citrucel) and pills or eat high fiber cereals. Alternatively, there are medications that can improve constipation. They include stool softeners such as docusate sodium and laxatives such as psyllium seed, methylcellulose, polycarbophil, and dextrans.

Why is my toddler's poop so hard?

Your young child may have constipation because he/she may have a tear in his/her anus, which could lead to voluntary holding due to pain with defecation. He/she may have less frequent bowel movements if he/she is in an environment where he/she does not feel safe and secure. Alternatively, your child's constipation may be due to a medical problem such as Hirschsprung disease, an abnormality in the anus, or an abnormality in the spinal cord.

What can I do for constipation when pregnant?

Ways to improve constipation during pregnancy include consuming plenty of fluids, eating a high-fiber diet, and maintaining a moderate amount of exercise. In addition, you may consider using laxatives approved for use during pregnancy if the above methods do not improve your constipation.
