Discover The Link Between SIBO And Your Mental Health

November 05, 20245 min read

If you have SIBO (Small Intestinal Bacterial Overgrowth), you probably know how uncomfortable it can make your stomach feel...

But did you know that SIBO can also impact your mental health? 😪😬

Yep, SIBO isn’t just about tummy troubles – it can also affect your mood, energy, and overall mental well-being. Let’s dive into how SIBO and mental health are connected and what you can do to feel better.

The Gut-Brain Connection

Scientists have discovered something amazing called the gut-brain connection. This means that our gut and brain “talk” to each other through a special pathway, called the gut-brain axis. If something goes wrong in the gut – like when there’s too much bacteria growing in your small intestine, which is what happens in SIBO – it can send “bad” messages to your brain. This can lead to mood changes, stress, and even anxiety and depression.

It is estimated that for every 1 message your brain sends to your gut, there are at least 10 messages in reply. The gut has a lot to say! 📢📢📢

SIBO causes inflammation in the gut, which doesn’t just stay in the stomach. This inflammation spreads and can mess with brain chemicals, like serotonin, which helps us feel calm and happy. So, if you’re dealing with SIBO, your gut might be sending messages to your brain that make it harder to stay upbeat and relaxed. And remember, the gut is more "chatty" than the brain, so that's a lot of altered messaging that the brain is hearing...👂

How SIBO Impacts Mental Health

Here’s a simplified way of looking at how SIBO affects your mood and mental well-being:

1. Inflammation Spreads: When there’s too much bacteria in the gut, it creates inflammation.⚡️ This inflammation doesn’t just stay in the digestive system – it can travel to other parts of the body, including the brain. When the brain is inflamed, it can lead to feelings of sadness, anxiety, and even irritability. This is because inflammation lowers serotonin production, which is a “feel-good” chemical in the brain.

2. Trouble Absorbing Nutrients: People with SIBO often struggle to absorb important nutrients, like vitamin B12 and magnesium. Both of these are super important for keeping your brain healthy and your mood steady. When you’re low on B12, magnesium, and other nutrients, it’s common to feel more anxious or down. So, SIBO can actually leave you feeling mentally drained just by not letting you get the nutrients you need.😫

3. Chronic Stress from Symptoms: Living with SIBO’s uncomfortable symptoms – like gas, bloating, and pain – can be stressful and frustrating. When these symptoms become a regular part of life, it’s easy to feel overwhelmed or stressed.😩 Over time, this constant stress can impact your mental health, making you feel more anxious and even depressed.

What Research Tells Us

Studies show that people with SIBO often report higher levels of anxiety and depression compared to people without it. In one study, every single person with SIBO reported feeling at least a little anxious or depressed.

(That's a pretty impressive statistic since there's very few 100% statistics in medicine.) 💯🤯

Another study found that people with SIBO have changes in tryptophan, which is a protein that helps make serotonin. When serotonin levels drop, our moods tend to drop too, leading to more feelings of sadness or worry.

How to Improve Mental Health with SIBO

The good news? There are ways to help improve your gut and mood. Here are a few tips:

- Eat a Gut-Friendly Diet: Eating a diet that supports your gut health is one of the best things you can do. Some people find that a low-fermentation diet, which limits foods that can cause gas and bloating, helps reduce symptoms. Talk with a doctor to figure out which foods are best for you and your gut. BUT, keep in mind that it is important NOT to restrict your diet for too long. Dietary restrictions longer than a couple months can lead to more problems down the road, or can ultimately make it harder to heal from your SIBO.

- Manage Inflammation: To keep inflammation in check, you can try eating foods that fight inflammation, like fruits, vegetables, and omega-3-rich foods (such as salmon and other fatty fish). Remember that cooked foods are already predigested and are an easier way for you to get these nutrients if you suspect or know that you have SIBO. Fruits and veggies that are blended into a smoothie are also predigested. Drinking plenty of water and avoiding sugary foods can also help reduce inflammation.

- Make Sure You’re Absorbing Nutrients: Since SIBO makes it harder for your body to absorb nutrients, consider adding foods rich in B12 (like eggs and meat) and magnesium (like cooked leafy greens) to your diet. In some cases, a doctor may recommend supplements to help you get what you need, especially if you have lab work like an elevated MMA (methylmalonic acid) to support a low B12 at the cellular level -OR- a low magnesium RBC to support a low magnesium level in your body.

- Practice Stress-Relief Techniques: Because stress can make SIBO worse, learning how to relax can make a big difference. Techniques like deep breathing 🌬️, guided meditation 🧘‍♀️, and hypnotherapy 😌 can lower stress and improve your parasympathetic nervous system which helps you rest and digest. Even short walks outside can lower stress and boost your mood! 🚶🏻‍♀️‍➡️

Key Takeaways

If you’re dealing with SIBO, remember that you’re not alone – and that there’s more to this condition than just gut discomfort. SIBO can impact your mental health, making you feel anxious, stressed, or down. But by understanding this gut-brain connection, you can take steps to help both your gut and your mind feel better.

If you or someone you know is struggling with SIBO and related mental health issues, consider reaching out to a healthcare professional who understands this gut-brain link. Healing your gut may be a journey, but it’s one that can lead to a happier, healthier you – inside and out.
