Using the Low FODMAP Diet to Relieve Constipation
The low FODMAP diet has become a popular approach for managing IBS symptoms like constipation. But transitioning to this restrictive diet involves some common pitfalls.
In this article, well explore the basics of a low FODMAP diet, how it helps constipation, and mistakes to avoid. Youll also learn how to implement this diet more easily under a dietitians guidance.
What is the Low FODMAP Diet?
FODMAP stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols. These are short-chain carbohydrates that can be hard to digest for some people.
FODMAPs are found in a wide variety of foods including fruits, vegetables, dairy, beans/legumes, and wheat products. They tend to pull water into the intestinal tract and get fermented by gut bacteria.
In those with IBS, consuming high FODMAP foods can trigger symptoms like gas, bloating, pain and constipation. The low FODMAP diet involves restricting high FODMAP foods for 4-8 weeks to identify problem foods, then systematically reintroducing them.
How Does It Help Constipation?
The low FODMAP diet may relieve constipation in a few ways:
- Reduces intake of fructans and GOS that are difficult to digest and may worsen stool consistency issues.
- Limits lactose, a FODMAP that many people with IBS have difficulty digesting.
- Low FODMAP foods boost production of beneficial gut bacteria linked to healthy bowel function.
Research shows around 70% of people with IBS find symptom relief from strict low FODMAP dieting. This includes improvement in constipation for many people.
Pitfall #1 - Restricting Too Many Food Groups
The biggest mistake when starting a low FODMAP diet is eliminating too many foods or entire food groups unnecessarily. This leads to inadequate nutrient intake and confusion about which foods actually trigger symptoms.
Work with a dietitian knowledgeable in FODMAPs. They can guide you through an elimination phase that methodically removes foods high in each type of FODMAP, rather than overly restricting your diet.
Pitfall #2 - Not Confirming Food Tolerances
After the initial FODMAP elimination phase of 4-8 weeks, its critical to methodically reintroduce higher FODMAP foods. This identifies your personal triggers versus foods you can tolerate.
Moving through this reintroduction phase under professional guidance ensures you dont end up needlessly restricting foods long-term. Keeping your diet more flexible improves compliance and nutrition.
Pitfall #3 - Neglecting Important Nutrients
Low FODMAP diets restrict or limit high-fiber foods, fruits, vegetables, dairy and grains - all sources of important nutrients.
Be vigilant about getting adequate fiber, calcium, vitamin D and B vitamins while following the diet. Your dietitian can recommend alternatives like lactose-free milk, coconut yogurt, and supplementation if needed.
Pitfall #4 - No Long-Term Planning
Many people find their IBS symptoms return after strict low FODMAP dieting if they dont establish an effective long-term plan.
Work with your dietitian to confirm your food intolerances, establish a sustainable diet, and implement appropriate lifestyle modifications. This provides the structure needed for lasting relief of constipation and other IBS issues.
Tips for Starting a Low FODMAP Diet
If you have IBS-related constipation, a low FODMAP diet may help provide relief. Here are some tips for getting started:
Check with Your Doctor
Always consult your physician before making major diet changes, especially for digestive issues. Your doctor can rule out other conditions and ensure the diet is appropriate for your individual case.
Find a Knowledgeable Dietitian
Work with a registered dietitian well-versed in the low FODMAP diet. They will ensure you understand the diet completely, support you through the elimination and reintroduction phases, and provide personalized meal plans.
Evaluate Your Baseline Symptoms
Track your current IBS symptoms and bowel habits for 1-2 weeks pre-diet. This gives you a baseline for comparison when assessing the diets effectiveness.
Plan Low FODMAP Meals and Snacks
Meal prep based on approved foods and have suitable low FODMAP snacks on hand. This makes it easier to stick to the diet, especially when first getting started.
Read All Food Labels
Avoid hidden sources of FODMAPs by reading food labels diligently. Watch out for ingredients like high fructose corn syrup, inulin, wheat, and milk derivatives.
Sample 1-Day Low FODMAP Diet Menu
Here is an example of a 1-day low FODMAP menu that avoids dietary pitfalls while providing balanced nutrition:
Breakfast
- Eggs cooked with spinach and tomato
- Gluten-free toast with peanut butter
- Low FODMAP fruit like blueberries
- Lactose-free milk or non-dairy alternative like almond milk

Partnering with a knowledgeable dietitian provides the guidance needed to implement this diet safely and effectively on a personalized basis.
With professional support, a low FODMAP diet often provides long-term improvement in IBS symptoms and quality of life.
