Why Does My Stomach Hurt When I Need to Poop?

Your stomach might hurt when you need to poop due to various reasons, including dehydration, food intolerances, or lack of fiber. At WHY.EDU.VN, we provide detailed explanations and potential solutions to help you understand and alleviate this discomfort. Identifying the cause and making necessary lifestyle adjustments can improve your digestive health and prevent future episodes of painful bowel movements, ensuring gut comfort and regular bowel habits.

1. Not Drinking Enough Water

Bowel movements consist of waste products excreted from your body, including both food and water.

“The body requires a certain amount of water to be absorbed before it eliminates excess in the stool. So if you do not drink enough water—or you need more water because of water loss for other reasons like sweating while you have a fever—bowel movements can become very hard and brittle,” explains Carolyn Newberry, MD, a gastroenterologist at NewYork-Presbyterian and Weill Cornell Medical Center.

This lack of water can lead to difficulty with stool passage and common symptoms of constipation, including straining, cramping, abdominal pain, and bloating.

1.1. What You Can Do About It

Drinking enough water or eating foods with high water content, like cucumbers, can help you stay hydrated, making your bowel movements easier to pass.

“Aim for six to eight cups of water per day, and make sure to limit beverages that can cause excessive water loss, like alcohol, coffee, and sugary beverages, which act as diuretics,” suggests Dr. Newberry. According to research from the University of California, maintaining adequate hydration levels significantly improves stool consistency and ease of passage.

2. Food Intolerance

“Sometimes abdominal discomfort and painful pooping may be caused by food intolerances such as lactose, fructose, or gluten,” says Christian Stevoff, MD, a gastroenterologist at the Digestive Health Center at Northwestern Medicine. “They can lead to abdominal distension and discomfort.”

2.1. What You Can Do About It

Some food intolerances can be diagnosed with tests, helping you avoid problematic foods and prevent pain. “Others require trial-and-error elimination diets to determine the offending agents,” Dr. Stevoff advises. A study published in the American Journal of Gastroenterology found that elimination diets can effectively identify trigger foods in individuals with chronic digestive issues.

3. Not Eating Enough Fiber

Fiber is indigestible plant matter that’s an essential part of a healthy diet and healthy bowel movements.

“There are two types, soluble—the kind that dissolves in water—and insoluble—the kind that doesn’t dissolve in water,” Dr. Newberry explains. “Soluble fiber helps stool retain water and keeps stools soft. Insoluble fiber helps bulk stool and makes it easier to pass. Both are important for your gut health and should be consumed daily.”

3.1. What You Can Do About It

“If pooping is painful, try increasing your intake of fruits, vegetables, and whole grains,” Dr. Newberry suggests.

“Most adults don’t meet the recommended daily fiber goals of 21 to 25 grams per day for women and 30 to 38 for men,” she adds. The healthiest way to add fiber to your diet is by eating fiber-rich foods. “If you have trouble getting all your fiber from food, try adding a daily supplement in the form of a powder, capsule, or bar.” According to a report by the National Institutes of Health, increasing dietary fiber intake can significantly improve bowel regularity and reduce constipation.

4. Lack Of Exercise

“Getting moving stimulates your muscles, and it also can make your gut move, change the way your stool absorbs water, and beneficially alters important hormone signals that regulate gut health,” says Dr. Newberry.

4.1. What You Can Do About It

“Incorporating aerobic exercise into your daily routine may alleviate the uncomfortable side effects of constipation and keep your heart and your whole body healthy in the process,” she advises. “Any activity that gets your heart rate up counts, so even if you don’t have time to get to the gym, you should still try to take a brisk walk or climb a flight of stairs.” Research from Harvard Medical School indicates that regular physical activity promotes healthy bowel function and reduces the risk of digestive issues.

5. Medications That Cause Constipation

“Some commonly prescribed medications can alter the way your bowel movements are passed by changing water absorption, hormone secretion, or motility of the gut itself,” explains Dr. Newberry.

Culprits can include antacids, narcotic pain medications, iron tablets, certain blood pressure medications, and antidepressants.

5.1. What You Can Do About It

Understand the common side effects of your medications, and if there is a concern they may be causing your constipation, talk to a healthcare provider about trying something else or using a stool softener. A study in the British Journal of Clinical Pharmacology highlights the importance of reviewing medication side effects with a healthcare provider to manage constipation effectively.

6. Irritable Bowel Syndrome

Irritable bowel syndrome (IBS) commonly causes abdominal pain and bloating, “but there are many different ways for IBS to present,” says Dr. Stevoff. Some people with IBS may have bowel spasms and diarrhea, while others have constipation.

6.1. What You Can Do About It

“Treatment is based on the symptoms you exhibit,” Dr. Stevoff explains. Besides lifestyle changes like diet, stress management, and exercise, there are also some medications approved for IBS treatment. The Rome Foundation emphasizes that a comprehensive approach, including dietary modifications and stress reduction, is crucial for managing IBS symptoms.

7. A Serious Medical Problem

If none of these other scenarios sounds familiar, it’s possible you could have an underlying medical problem that’s decreasing your ability to pass bowel movements easily and effectively.

“These include blockages in your intestines from twisting or masses, damage to the muscles in your gut from surgery or childbirth, damage to the nerves in your gut from nervous system diseases like Parkinson’s, or inflammation in the colon from a number of causes,” Dr. Newberry explains.

7.1. What You Can Do About It

Talk with your healthcare provider about your symptoms. “Any gastrointestinal bleeding (in the stool, in the toilet, or on the paper) should be evaluated by a healthcare provider,” Dr. Stevoff advises. “Likewise, other alarming features—such as unintentional weight loss, fevers or chills, nausea or vomiting, and abdominal pain that is severe and unremitting—should be evaluated right away.” The Mayo Clinic recommends seeking immediate medical attention for severe or persistent gastrointestinal symptoms to rule out serious underlying conditions.

8. Understanding the Gut-Brain Connection

The gut-brain connection plays a significant role in digestive health. Stress and anxiety can directly impact your digestive system, leading to symptoms like stomach pain and constipation.

8.1. How Stress Affects Your Bowels

When you’re stressed, your brain releases hormones and neurotransmitters that can disrupt the normal functioning of your digestive system. This can result in increased sensitivity to pain, changes in gut motility, and altered gut bacteria composition.

• Increased Pain Sensitivity: Stress can lower your pain threshold, making you more aware of discomfort in your abdomen.
• Altered Gut Motility: Stress can either speed up or slow down the movement of food through your digestive tract, leading to diarrhea or constipation.
• Changes in Gut Bacteria: Stress can disrupt the balance of bacteria in your gut, which can contribute to inflammation and digestive symptoms.

8.2. Managing Stress for Better Digestive Health

Effective stress management techniques can help alleviate stomach pain and improve bowel function. Consider incorporating these practices into your daily routine:

12.1. Optimal Meal Timing Strategies

• Eat Regular Meals: Try to eat your meals at consistent times each day to regulate your digestive system.
• Avoid Late-Night Eating: Eating a large meal close to bedtime can disrupt sleep and lead to digestive discomfort. Allow at least 2-3 hours between your last meal and bedtime.
• Eat Smaller, More Frequent Meals: Eating smaller meals more frequently throughout the day can help prevent overeating and reduce the strain on your digestive system.

12.2. The Importance of Mindful Eating

Practicing mindful eating can also improve digestion. Mindful eating involves paying attention to the taste, texture, and smell of your food, and eating slowly without distractions.

• Chew Your Food Thoroughly: Chewing your food thoroughly helps break it down and makes it easier to digest.
• Eat Slowly: Eating slowly allows your brain to register fullness, which can prevent overeating.
• Eliminate Distractions: Turn off the TV and put away your phone while eating to focus on your meal.

A study published in the Journal of the Academy of Nutrition and Dietetics found that mindful eating practices can improve digestive health and promote weight management.
