Weight Gain When Constipated: Causes, Solutions & Prevention

MyFitnessCoach
April 9, 2025
Have you ever noticed that when you are constipated, you feel bloated and heavier than usual? This might make you wonder if constipation can actually cause you to gain weight. The simple answer is yes, but not in the way most people think about weight gain. When you are constipated, your body holds on to waste, which can lead to temporary weight changes. You may also experience water retention and bloating, which can make you feel even heavier. However, this type of weight gain is not due to an increase in body fat. Instead, it is just a temporary effect that goes away once your digestion returns to normal.
In this article, we will discuss how constipation affects your weight, what causes it, and how you can manage it effectively. By the end, you'll also learn how a fitness app like MyFitnessCoach can help you maintain healthy digestion and avoid weight fluctuations due to constipation.
Common Causes of Constipation
Not Eating Enough Fiber
Fiber is an important part of your diet because it helps your body form soft, bulky stools that move easily through the intestines. If you do not eat enough fiber-rich foods like fruits, vegetables, and whole grains, your stools may become small and hard, making it difficult to have regular bowel movements. This can lead to constipation.
Not Drinking Enough Water
Your body needs plenty of water to keep your stools soft and easy to pass. If you do not drink enough fluids, your stool can become dry and hard, which makes it difficult to pass through the intestines. This can lead to constipation and discomfort.
Not Being Physically Active
Regular physical activity helps keep your digestive system working properly. When you move your body, it stimulates your intestines and helps food move through your system. However, if you spend too much time sitting or lying down and do not exercise enough, your digestion can slow down, increasing the risk of constipation.
Ignoring the Need to Use the Bathroom
When you feel the urge to have a bowel movement, it is important to go as soon as possible. If you hold it in for too long, your stool can become harder and drier, making it more difficult to pass later. Ignoring the urge regularly can lead to constipation over time.
Stress and Worry Affecting Digestion
Your brain and gut are closely connected, which means that stress and anxiety can have an impact on your digestion. When you are feeling stressed, your digestive system may slow down, making it harder for your body to pass stools. This can contribute to constipation, especially if stress is a frequent issue in your life.
Side Effects of Certain Medications
Some medicines can slow down your digestive system and cause constipation. Common medications that can have this effect include painkillers, antidepressants, and iron supplements. If you are taking any of these medications and notice that you are having trouble with constipation, you may need to speak with a doctor for advice.
Health Problems That Cause Constipation
Certain medical conditions can make constipation a long-term problem. For example, Irritable Bowel Syndrome (IBS) can cause digestive discomfort, while hypothyroidism (an underactive thyroid) can slow down your metabolism, including digestion. Diabetes can also affect how your body processes food. If you frequently experience constipation, it may be linked to an underlying health condition that needs medical attention.
How to Relieve Constipation and Avoid Weight Gain
1. Eat More Fiber
Include fiber-rich foods in your diet, such as:
- Fruits (apples, pears, bananas, berries)
- Vegetables (broccoli, carrots, spinach)
- Whole grains (oats, brown rice, whole wheat bread)
- Nuts and seeds (flaxseeds, chia seeds, almonds)
Fiber adds bulk to the stool and promotes regular bowel movements.
2. Stay Hydrated
Drink at least 8-10 glasses of water daily. Proper hydration softens stool and prevents constipation.
3. Exercise Regularly
Physical activity helps stimulate bowel movements. Try:
- Walking
- Yoga
- Pilates
- Running
- Strength training
4. Establish a Routine
Try to go to the bathroom at the same time every day. Creating a regular schedule can help your body develop a natural rhythm.
5. Reduce Stress
Practice relaxation techniques such as deep breathing, meditation, and mindfulness to keep stress levels in check.
6. Avoid Processed Foods
Junk foods, sugary drinks, and refined grains can slow digestion and cause constipation. Opt for whole, unprocessed foods instead.
7. Take Probiotics
Probiotics support gut health and aid digestion. Yogurt, kefir, and fermented foods like sauerkraut and kimchi are great probiotic sources.
8. Use Natural Laxatives
Some natural laxatives include:
- Prunes
- Aloe vera juice
- Psyllium husk
- Flaxseeds
If constipation persists, consult a doctor before using over-the-counter laxatives.
