Hi everyone. Today's question is, should I take antibiotics for sibo? And the answer is that it really depends on the individual situation. Antibiotics are not inherently wrong. They also don't look at the whole picture. So in clinical practice, I kind of see two different types of patients when it comes to sibo. So the first group of people whose lifestyle make it extremely difficult to follow the kind of treatment approach that natural SIBO protocols usually require. So people such as Flight attendants who are constantly traveling across time zones and eating whatever food is available during flights. Or someone may travel frequently for work and simply doesn't have control over what they eat. Or sometimes people are already very underweight and the SIBO diet can cause further weight loss, which isn't appropriate for them. So in those types of situations when lifestyle restrictions make dietary and herbal protocols very difficult to implement and actually stressful and stress can also cause sibo, it becomes counterproductive. So for people like them, antibiotics can actually be a reasonable option. They can reduce the bacterial load relatively quickly without requiring major changes to diet and routine. So in some cases, I absolutely say to patients, given your circumstances, antibiotics may be the most practical place to start. But in the majority of patients who come to see me, they're actually the opposite situation. So many of them have already taken several rounds of antibiotics and the SIBO keeps coming back. They simply don't wanna go down that path again. They want to understand why it developed in the first place and address the underlying drivers. So this is what I was discussing in my episode on Tuesday, all the underlying drivers of SIBO and why it keeps coming back. So if I have a patient sitting in front of me who is motivated, who can cook their own food, who is willing to follow a structured treatment protocol, then I'll usually encourage a more comprehensive approach rather than relying. On antibiotics alone, and that's because SIBO really occurs for just one reason. So sometimes there's a single trigger. For example, an episode of food poisoning that disrupts gut motility. And if that is the case in that person who can't really do the natural protocol, then that's a classic example of someone that I'm like, hey, antibiotics might just be right for you in this instance, and they'll go off and get antibiotics. But often people will say, I don't wanna take antibiotics, Joe. It put me in this mess in the first place. Sometimes it's just one driver, but in many people there are multiple, multiple factors happening at the same time, which I discussed in the episode on Tuesday, all about why SIBO keeps coming back, so you can check out that episode. So for those people who can follow a structured treatment approach. A natural treatment approach for sibo, it takes about three to four months. This often includes dietary modification, herbal antimicrobials, where appropriate and support for the underlying physiology of digestion. So things like bowel flow, stomach acid production, motility issues, nervous system regulation, and that's why I'm such an advocate of the natural approach. It's because we can observe the body's response. So the gut behaves like layers of an onion as we peel back one layer new information appears. So for example, if someone follows a SIBO protocol and remains extremely bloated, that may point us towards motility issues involving the migrating motor complex. You might actually have some hydrogen sulfide sibo, not just methane or hydrogen. You might have SIFO, small intestinal fungal overgrowth, and this can all kind of appear in the second or third consult. Sometimes we see clues pointing towards bile flow issues, so if your bile not improving, it can be due to Eastern dominance. Or it could be a mold issue if you have multiple food intolerances that keep remaining if your histamine bucket stays high. We need to actually be aware of that in the second, third consult so we can actually shift gears and look further, you know, and look further down and look for more and more causes.'cause you don't wanna do that whole protocol for three or four months without getting to the end with your SIBO cleared. So if you're dealing with SIBO and trying to decide which direction to take, this is something we work with with patients all the time in clinic. I see patients online globally via Zoom.
