The above charts are both used when determining stool quality. Admittedly, one is more easy to remember than the other! Let’s dive into what these numbers (or shapes) mean:


What does each stool type indicate?

The Bristol Stool Chart consists of seven different stool types, each representing a different aspect of your digestive health. Understanding the common causes of different stool types can help you identify potential issues and make necessary adjustments to improve your digestive health! Let’s take a closer look at what each stool type indicates:

Type 1: Separate hard lumps

This type of stool indicates severe constipation. It consists of hard, dry, and difficult-to-pass lumps. It may be a sign that you need to increase your fiber intake and hydrate adequately. It can also be indicative of constipation-type IBS (IBS-C).

Type 2: Sausage-like but lumpy

Stool type 2 is slightly easier to pass than type 1, but it still suggests constipation. It may indicate that you need to incorporate more fiber-rich foods into your diet and establish a regular bowel movement routine.

Type 3: Sausage-shaped with cracks

This stool type is considered normal and ideal. It resembles a sausage with cracks on the surface. It is easy to pass and indicates a healthy digestive system.

Type 4: Smooth and snake-like

Similar to type 3, stool type 4 is smooth and soft. It is also easy to pass and signifies good digestive health. This is the goal you should strive for.

Type 5: Soft blobs with defined edges

Stool type 5 is still considered within the range of normal, but it indicates a shorter transit time through your digestive system. It may be a sign that you need to assess your diet.

Type 6: Fluffy pieces with ragged edges

Stool type 6 suggests mild diarrhea. It is often associated with a high intake of certain foods or an imbalance in your gut microbiome. It may be necessary to make dietary adjustments to restore balance or go through a microbiota rebalancing protocol.

Type 7: Watery and entirely liquid

Stool type 7 indicates severe diarrhea. It is a clear sign of an underlying digestive issue, such as an infection or food intolerance. It is crucial to seek medical advice if you consistently experience this stool type, as long term consequences of nutrient deficiencies are high and long-term irritation of the GI tract can increase the risk of autoimmune disease.

1. Hard, lumpy stools (type 1) are often caused by a lack of dietary fiber, dehydration, or a sedentary lifestyle. Increasing your fiber intake, drinking plenty of water, and staying active can help alleviate this issue. If you are already doing these things, the next step would be aiming to rebalance gut flora with a comprehensive gut-restoration protocol.

2. Sausage-like but lumpy stools (type 2) are also a result of inadequate fiber intake, dehydration, or a lack of physical activity. Adding more fiber-rich foods such as vegetables and fruits to your diet can help regulate your bowel movements.

3. Sausage-shaped with cracks (type 3) is the ideal stool type. It indicates a healthy balance of fiber, hydration, and regular bowel movements. If you consistently have this stool type, you’re doing a great job!

4. Smooth and snake-like stools (type 4) are also indicative of a healthy digestive system. This type suggests that your diet and lifestyle are supporting good gut health.

5. Soft blobs with defined edges (type 5) may be caused by a slight imbalance in your gut microbiome or certain dietary choices. Evaluating your diet and possibly incorporating more probiotic-rich foods or supplements can help regulate your bowel movements.

6. Fluffy pieces with ragged edges (type 6) often indicate a mild case of diarrhea. It can be caused by consuming certain foods that your body may not tolerate well or imbalances in your gut bacteria. Identifying trigger foods and making dietary adjustments can help alleviate this issue.

7. Watery and entirely liquid stools (type 7) are a clear sign of severe diarrhea. This can be caused by infections, food intolerances, or other medical conditions. It is essential to consult a healthcare professional if you experience this stool type regularly due to the risk of disease if left unaddressed. 

The importance of regular bowel movements

Regular bowel movements are crucial for maintaining good digestive health. When waste products accumulate in your colon for an extended period, they can be reabsorbed into your body, leading to various health and hormone problems. Additionally, whatever may be causing bowel troubles may also be leading to bowel inflammation, which can lead to or exacerbate food intolerances, immune dysregulation, and nutrient deficiencies.

Aim to have a bowel movement at least once a day. If you experience infrequent bowel movements or irregularities, or your bowel movements feel incomplete, it may indicate an underlying issue that needs attention. Paying attention to your stool type, as indicated by the Bristol Stool Chart, can help you gauge your bowel regularity.

How to Best Utilize the Bristol Stool Chart

Using the Bristol Stool Chart is simple. Each time you have a bowel movement, observe the characteristics of your stool and compare it to the seven types on the chart. If you want to have fun with it, use the pediatric version! Determine which type closely matches your stool and note it down.

Keep track of your stool types over a week or two to establish patterns. This will provide you with a better understanding of your digestive health. If you notice consistent deviations from the ideal type 3 or 4, it may be worth exploring potential causes and making appropriate changes. Start to assess if certain foods repeatedly appear within 24 hours of troubles, or if stress may be a factor for you.

Tips for maintaining a healthy digestive system

It goes without saying that maintaining a healthy digestive system goes beyond just monitoring your stool type. Here are some general tips to optimize your gut health:

1. Eat a balanced and fiber-rich diet (more on this below): Incorporate plenty of vegetables, fruits, and legumes into your meals. These foods provide essential nutrients and contribute to good digestion. If you struggle to digest these foods, a free discovery call to talk about options to correcting this problem may be helpful for you.

2. Stay hydrated: Drink an adequate amount of water throughout the day to keep your stools soft and easy to pass.

3. Exercise regularly: Physical activity helps stimulate bowel movements and promotes overall gut health. Aim for at least 30 minutes of moderate exercise most days of the week. Walking, jogging, lots of squats and yoga are great for digestion!

4. Manage stress levels: Stress can have a significant impact on your digestive system. Practice stress-reducing techniques such as meditation, laughter via comedy or that hilarious person you know, or regularly engage in hobbies you enjoy.

5. Avoid trigger foods: If certain foods consistently cause discomfort or irregular bowel movements, consider eliminating or reducing their consumption. Food intolerances or sensitivities can disrupt your digestive system and may contribute to GI inflammation.

Diet and lifestyle changes for optimal digestive health

Making specific dietary and lifestyle changes can have a significant impact on your digestive health. Here are some recommendations to consider:

Increase fiber intake: Aim for a combined 6-10 servings per day of vegetables, fruits and legumes. Fiber adds bulk to your stools and promotes regular bowel movements. The fiber-rich foods I listed are also very rich in essential nutrients to preserve whole-body health. They tend to be better tolerated than fiber supplements or fiber-fortified cereals. Some fibers increase gas in certain individuals, so you may need to make some adjustments based upon your gut microbiome and digestive tolerance. The tips I share here can go a long way to reducing gas from crucifers and beans, specifically.

Probiotics and prebiotics: Incorporate probiotic-rich foods like yogurt, kefir, sauerkraut, and kimchi into your diet to support a healthy gut microbiome. These are foods which were regularly consumed for generations before we became terrified of bacteria. Now, we have a lack of beneficial bacterial diversity and these foods are essential to changing that! Prebiotics, found in foods like onions, garlic, artichokes and bananas, provide nourishment for beneficial gut bacteria and are also important to consume regularly. 

3. Limit processed foods: Processed foods are often low in fiber and high in unhealthy fats, which can disrupt your digestive system. Opt for whole, unprocessed foods whenever possible. Did great-grandma eat it? Do bugs go after it? Does it rot quickly? These types of foods should make up 80% of our fare.

4. Drink plenty of water: Staying hydrated is essential for maintaining soft stools and preventing constipation. While the general recommendation is to drink at least eight glasses of water per day, body size, activity level, and ambient temperature have a big impact on this! Aim to have straw colored urine in the toilet; this is the best indication of hydration for you.

5. Chew your food thoroughly: Properly chewing your food aids in digestion and helps prevent digestive discomfort. Take your time and enjoy your meals mindfully. Most of my clients finish their meals in less than 7 minutes. If this is you, set a timer and stretch it out to ten, then 15. See if you can take 20 minutes to eat a meal, even if you only have time to do this once per day.

When to see a doctor about your stool type

While the Bristol Stool Chart is a helpful tool for monitoring your digestive health, there are instances when it’s essential to consult a healthcare professional. If you experience any of the following, seek medical advice:

1. Persistent changes in stool type without any apparent cause.

2. Blood in your stool.

3. Unexplained weight loss.

4. Severe abdominal pain or cramping.

5. Frequent diarrhea or constipation that lasts for an extended period.

These symptoms may indicate underlying health conditions that require medical attention. Your doctor can provide a proper diagnosis and recommend appropriate treatment.

Other factors to consider for digestive health

While the Bristol Stool Chart provides valuable insights into your digestive health, it’s essential to consider other factors that contribute to overall well-being. Here are some additional considerations:

1. Gut microbiome: Your gut microbiome plays a crucial role in digestion and overall health. Nurturing a diverse and balanced gut microbiome through a healthy diet, probiotics, and prebiotics is key.

2. Stress management: Chronic stress can disrupt your digestive system. Assessing your unique stressors, finding strategies to combat what you can control and release what you cannot will go a long way to improving your digestive health. Aside from typical stress reduction techniques, cognitive behavioral therapy, EFT, and intentionally integrating that which makes you smile into your day can ease the tension you carry from day to day.

3. Medications and supplements: Certain medications and supplements can impact your digestive system. If you experience any digestive issues after starting a new medication or supplement, consult your healthcare provider.

4. Food intolerances and allergies: Some individuals may have specific food intolerances or allergies that affect their digestive system. Identifying and avoiding trigger foods is crucial for maintaining digestive health.

By considering these additional factors alongside the Bristol Stool Chart, you can gain a more comprehensive understanding of your digestive health.

Conclusion: Taking control of your digestive health

Understanding the Bristol Stool Chart is the first step in decoding your digestive health. By paying attention to your stool type, you can gain valuable insights into your gut health. However, it is when we make the necessary dietary and lifestyle adjustments that we are really able to optimize the digestive system!
