Small Intestinal Bacterial Overgrowth (SIBO)

Q I was diagnosed with IBS. Could it actually be SIBO? Does Korean medicine distinguish between and treat the two conditions?

A. A significant proportion of IBS patients are known to have concurrent SIBO. By carefully identifying symptom patterns and triggers, a treatment plan considering both can be established.

Q If there are many bacteria in the small intestine, does nutrient absorption also worsen? What symptoms actually appear?

A. When SIBO becomes chronic, absorption of fat, protein, vitamin B12, iron, and fat-soluble vitamins (A, D, E, K) decreases. This can cause chronic fatigue, anemia, osteoporosis, dry skin, and reduced immunity.

Q I have hypothyroidism and heard that SIBO occurs more easily with it. Can I be treated for both conditions together?

A. Hypothyroidism slows gut motility overall, raising the risk of developing SIBO. By maintaining your thyroid medication while combining Korean medicine treatment focused on restoring small-intestine motility, both conditions can be managed together.

Q How should I eat to benefit SIBO?

A. Eat small amounts frequently and chew slowly. Reduce high-FODMAP foods (garlic, onion, wheat, legumes) and maintain 4–5 hour meal intervals to give the small intestine enough time to move the previous meal along.

Q I work delivery in Dong-incheon with irregular meals and high stress. Lifestyle management is not easy — what should I do?

A. Irregular meals and stress directly impair small intestinal motility and worsen SIBO. Even if you cannot fix everything perfectly, it is important to start with what is possible — slightly aligning meal times and reducing binge eating.

Q My belly is very bloated and I have severe gas. What symptoms require urgent hospital care?

A. Severe abdominal pain, persistent vomiting, blood in stool, rapid weight loss, or severe nutritional deficiency symptoms (hair loss, dry skin, extreme fatigue) require immediate hospital care. These may indicate serious conditions beyond SIBO.

Q I've been taking acid-suppressing medication (PPI) long-term. Is it related to SIBO? Can I receive Korean medicine treatment alongside it?

A. Long-term PPI use reduces gastric acid's bactericidal action and can increase the risk of SIBO. Combining Korean medicine treatment is possible; consult the prescribing doctor about whether to reduce the PPI if appropriate.

Q Will treatment make the bloating completely disappear? How long does it take?

A. SIBO symptoms can greatly reduce with treatment but relapse is common. The goal is a noticeable reduction in bloating frequency and intensity within 1–3 months when combining small intestinal motility recovery and dietary management.

Q I relapsed after antibiotic treatment. Is there a way to prevent relapse?

A. SIBO relapse is frequent when the root cause (decreased small intestinal motility, insufficient gastric acid, etc.) remains. Simultaneously managing the root cause, restoring small intestinal motility, and sustaining a low-FODMAP diet can extend the interval between relapses.

Q What is SIBO? Why do bacteria increase in the small intestine?

A. SIBO is a condition where bacteria abnormally proliferate in the small intestine, causing abdominal bloating, gas, and impaired nutrient absorption. Main causes include decreased small intestinal motility, reduced gastric acid secretion, and ileocecal valve dysfunction.

Q Since my abdominal surgery, my belly bloats every time I eat. Is this related to SIBO?

A. Abdominal surgery can slow small intestinal motility due to adhesions and structural changes, making SIBO more likely. It is important to accurately identify the cause by checking the surgical site and intestinal condition.

Q They say I should follow a low-FODMAP diet. What can I actually eat?

A. FODMAPs are carbohydrates that are poorly absorbed in the small intestine and trigger bacterial fermentation. Limiting garlic, onion, beans, wheat, apples, and dairy while choosing low-FODMAP foods like white rice, tofu, chicken, carrots, and cucumber reduces symptoms.

Q I've been eating yogurt, kimchi, and probiotics thinking they were healthy, but my stomach feels more bloated. Why?

A. When SIBO is present, fermented foods and probiotics can further increase bacteria in the small intestine and worsen bloating. During treatment, it is recommended to temporarily reduce or stop fermented foods and probiotic supplements.

Q I want to receive Korean medicine treatment for SIBO near Dong-gu, Incheon. How often do I need to visit?

A. Usually during the first 1–2 months, acupuncture treatment 1–2 times per week combined with herbal medicine. As symptoms stabilize, visits decrease to every 2 weeks or once a month. If visiting is difficult, it is also possible to proceed mainly with herbal medicine while receiving dietary guidance.

Q I was told to get a hydrogen breath test for SIBO diagnosis. Is this test accurate?

A. The hydrogen/methane breath test is the most widely used non-invasive method for SIBO diagnosis. It has possibilities of false positives and false negatives, so comprehensive judgment together with clinical symptoms is important.

Q How does Korean medicine treatment for SIBO proceed step by step?

A. Step 1 is intestinal environment regulation (bacterial suppression and damp-heat removal), Step 2 is small intestinal motility recovery, and Step 3 is relapse-prevention maintenance treatment. Each stage is approximately one month and is adjusted according to symptom changes.

Q I took prescribed antibiotics and improved temporarily, but worsened again after a few months. Can Korean medicine help fundamentally?

A. Antibiotics temporarily suppress overgrown bacteria, but if the underlying cause (decreased small intestinal motility, etc.) remains, relapse is frequent. Korean medicine excels at restoring small intestinal motility to create an intestinal environment resistant to relapse.

Q Just 30 minutes after eating, my belly swells up like a mountain and I have massive gas. Does Korean medicine actually help?

A. Rapid post-meal bloating and excessive gas are hallmark symptoms of SIBO. Combining treatment to restore small intestinal motility and reduce intestinal fermentation with dietary management usually leads to a clear reduction in frequency and intensity.
