Q&A: Is LDN a Good Prokinetic for SIBO? Does LDN Help the MMC?

0 Comments

Read Now
 
This video delves into the nuances of prokinetics and their effectiveness, particularly in the context of SIBO (Small Intestinal Bacterial Overgrowth).
  • Individual Variability of Prokinetics: The discussion highlights that prokinetic treatments differ significantly in their effects from person to person. What works wonders for one individual may have little to no impact on another.
  • Low Dose Naltrexone (LDN) as a Prokinetic:
    • While not technically classified as a prokinetic, LDN has demonstrated prokinetic effects in studies, largely due to its influence on opioids in the body.
    • For some, LDN can be "phenomenal," leading to no relapses and offering additional benefits such as anti-inflammatory properties, immune system balance, and mood improvement.
    • However, for others, LDN may not be a strong enough prokinetic.
  • LDN and Severe SIBO:
    • LDN is often not sufficient for individuals with severe or recalcitrant SIBO, especially when underlying conditions like Ehlers-Danlos syndrome or scleroderma are present.
    • In such cases, a combined approach using LDN alongside another prokinetic, especially pharmaceutical, is recommended.
  • Pharmaceutical Prokinetic Options: When LDN is insufficient, stronger interventions are necessary:
    • Prucalopride (marketed as Motegrity in the US).
    • Low-dose Erythromycin
  • Conclusion: The effectiveness of any treatment, especially prokinetics, requires individual assessment. Trying different options is key to finding what works best.

Products Mentioned:
Prokinetics (pharmaceutical):
~ LDN (low dose Naltrexone - low dose has very different effects vs regular dose)
~ Prucalopride (Motegrity)
~ Low Dose Erythromycin

Q&A: Do I Need Digestive Enzymes If My Poop Floats?

0 Comments

Read Now
 
Key Discussions:
  • Interpreting Stool Characteristics: The video addresses the common practice of evaluating stool by its tendency to float or sink. The speaker notes that, based on their training, little definitive information can be reliably gathered from this observation. While opinions may differ, this method is not considered a primary indicator.
  • Signs of Fat Malabsorption: A more significant indicator discussed is fat malabsorption, which can result in greasy, sticky stools often accompanied by a strong, unpleasant odor. However, it's also highlighted that fat malabsorption can occur even when these specific stool characteristics are not present.
  • Assessing Digestive Enzyme Effectiveness: The primary method recommended for judging the efficacy of digestive enzymes is by observing their impact on how you feel after taking them. The key question is whether your symptoms are improving and if your overall digestive experience is becoming better.
  • Types of Digestive Enzymes: A variety of digestive enzymes are available, including those based on pancreatic enzymes, brush border enzymes, combinations, and predominantly plant-derived enzymes.
  • Specific Enzyme Products Mentioned: Several enzyme products are named as examples of effective options, including:
    • Digest Gold by Enzymedica
    • Digest Ultimate (previously Platinum)
    • Holozyme, a product developed by Steve Wright, noted for the extensive research behind it.
Takeaways and Recommendations:
  • Focus on Symptom Improvement: When considering digestive enzymes, the most reliable measure of their success is whether they lead to a reduction in symptoms and an overall improvement in well-being.
  • Diverse Enzyme Options: There are many effective digestive enzyme formulas on the market. If one doesn't yield the desired results, exploring other types, such as pancreatic-based, brush border, or plant-based options, is advisable.
  • Personal Experience: Dr. Allison Siebecker has personally used and appreciated plant-based enzymes, observing positive responses from others who have used them.

Q&A: Previous Food Poisoning; Stool Test Negative, BMs Still Abnormal - What to Test Next?

0 Comments

Read Now
 
This video delves into the connection between food poisoning and SIBO (Small Intestinal Bacterial Overgrowth), discussing various diagnostic methods and their nuances.

Key Discussions and Takeaways:
  • SIBO as a Consequence of Food Poisoning: The video highlights that food poisoning can be a primary cause of SIBO, often manifesting as a delayed reaction months afterwards.
  • Diagnostic Tools for SIBO:
    • Breath Test: Mentioned as a standard diagnostic method for SIBO.
    • IBS Smart Test: This blood test is specifically noted as a way to diagnose SIBO that may stem from food poisoning.
  • Stool Testing Sensitivity:
    • The video contrasts the sensitivity of stool testing from different laboratories.
    • LabCorp and Quest Diagnostics are cited as having stool tests that are less sensitive for parasites and functional stool testing.
    • Tests from GI Map, Genova, and Vibrant America are mentioned as potentially more sensitive options for functional stool testing.
  • Timing and Stool Testing for Food Poisoning: It's emphasized that pathogenic organisms responsible for food poisoning are typically cleared from the stool relatively quickly after the initial illness. Therefore, a stool test performed after the event might not detect the original pathogen.
  • Direct-to-Consumer Functional Stool Testing:
    • Rupa Labs is highlighted as a service where individuals can order their own functional stool testing.
    • ​While self-ordering is possible, the interpretation of results still requires consultation with a healthcare practitioner.

Oregano (ADP) isn't helping my SIBO? Why not?

0 Comments

Read Now
 
The video addresses what to do for hydrogen and methane positive levels (SIBO and IMO) and why Oregano hasn't helped symptoms after 9 weeks. 

Highlights:
  • Treatment Insights: Oregano is used for hydrogen. Interphase is a biofilm treatment. It is suggested to incorporate Allimed (often sold as Allimax Pro) or Atrantil for methane, for better results.
  • Prescription Alternatives:
    • For those considering prescription options, neomycin, metronidazole, or Alinia (nitazoxanide) are mentioned as options to add to Rifaximin for methane.
  • Evaluation of Treatment Plans:
    • Dr. Allison Siebecker emphasizes the importance of having a complete treatment plan and suggests retesting after nine weeks if symptoms persist, as this duration is longer than typical treatment courses.
Key Takeaways:
  • Comprehensive Treatment Approach:
    • It's crucial to address both hydrogen and methane for effective treatment of SIBO and IMO.
    • Biofilm treatments like Interphase can be beneficial, but may need to be supplemented with other products for optimal results.
  • Importance of Retesting:
    • Regular evaluation and retesting are important to ensure the effectiveness of the treatment plan and to make necessary adjustments.
Conclusion:
  • Oregano alone is not a complete treatment plan when both hydrogen and methane are positive. Add Allimed/Allimax Pro or Atrantil for methane. 

Products Mentioned:
- Oregano ADP: (Amazon), or (exclusive pricing at Fullscript)
- Allimed/Allimax Pro: (Fullscript), or (Hollywood Homestead)
- Atrantil: (Amazon), or (exclusive pricing at Fullscript)
- Methane antibiotics (added to Rifaximin/Xifaxan): Neomycin, Metronidazole, Nitazoxanide
