Overgrowths: How to tell if your gut or skin has gone out of balance
Feeling bloated, gassy, tired, or dealing with persistent thrush or skin yeast? Those are common signs that bacteria or fungi are growing where they shouldn’t. "Overgrowth" usually means an imbalance — either too many bacteria in the small intestine (SIBO) or excess Candida/yeast on the skin, mouth, or gut. Both cause symptoms that overlap with other conditions, so the first step is to narrow down what’s likely happening.
Signs and tests that actually help
Watch for patterns. SIBO often brings bloating within an hour or two of eating, frequent gas, loose stools or constipation, and sometimes nutrient gaps or weight loss. Candida overgrowth tends to show as oral thrush, persistent vaginal yeast infections, sugar cravings, or recurring skin rashes in warm, moist areas.
Useful tests: a lactulose or glucose breath test is the standard, noninvasive way to detect SIBO. For Candida, doctors rely on physical exam, swabs, and sometimes stool testing or targeted cultures. Blood antibody tests for yeast exist but aren’t always definitive. Don’t skip the basics: your provider will check medications (like long-term antibiotics or proton pump inhibitors), bloodwork, and medical history that make overgrowth more likely.
Practical steps you can start today
Don’t self-prescribe antibiotics or antifungals without a diagnosis — that can make things worse. Instead try these practical moves while you sort testing and a plan with your clinician:
- Eat with intention: reducing high-FODMAP foods and cutting back on simple sugars often reduces fermentation and symptoms fast. This isn’t a forever diet, but a short-term tool while you treat the problem.
- Talk to your doctor about targeted therapy: SIBO often responds to specific antibiotics prescribed for that purpose. Candida may need topical or oral antifungals depending on location and severity.
- Consider probiotics carefully: some people benefit, others don’t. Pick strains with evidence for gut balance and discuss timing with your clinician so they don’t interfere with treatment.
- Fix underlying causes: low gut motility, prior abdominal surgery, or chronic PPI use can allow overgrowth to return. Addressing these is as important as killing microbes.
If symptoms are severe — unintentional weight loss, high fever, bloody stools, or severe abdominal pain — get urgent care. For persistent or recurring problems, see a gastroenterologist or infectious disease specialist who knows how to test, interpret results, and design a stepwise plan.
