Gut Dysbiosis Symptoms, What To Watch Out For

One system to rule them all, the microbiome.

The microbiome is a unique ecosystem that exists inside the gastrointestinal tract, which is made up of trillions of microorganisms. In a healthy, balanced gut, these microbes communicate with various body systems to support daily metabolic functions and support health.

These microbes:

• Help support appropriate digestion
• Help produce Vitamins
• Help train the immune system to respond to pathogens
• Help support mood and behavior
• And so much more.

A child’s microbiome begins forming before birth and continues maturing throughout infancy and well into childhood. Several factors throughout pregnancy and during a child’s upbringing can influence microbiome development. The first 1,000 days of life are critical to help ensure appropriate microbiome development.

Several Key Influences Include:

• Prenatal support
• Prenatal Diet
• Mode of Delivery (Caesarean Section or Vaginal Delivery)
• Breastfeeding vs Formula feeding
• Introduction of Solid Foods
• Environmental Exposures including pets, outdoor activity, cleaning products, and water sources
• Dietary diversity

Gut dysbiosis occurs when the microbiome is disrupted. This imbalance can be due to several things, including too few beneficial bacteria, too many opportunistic pathogens, or reduced diversity. Dysbiosis rarely shows up as one clear symptom; it often resembles a pattern of ongoing or recurring symptoms.

Some common signs of Gut Dysbiosis include:

• Digestive Symptoms: chronic constipation or diarrhea, excessive gas/belching, or abdominal pain
• Frequent illnesses
• Chronic Skin conditions: eczema, chronic diaper rashes, hives
• Food Sensitivities
• Picky Eating
• Behavioral concerns: irritability, mood swings, anxiety, difficulty with focus, and sleep issues.

If your child experiences any of the symptoms above, it is always worthwhile to consult with your physician to discuss your concerns. It is important to note that not every symptom above means your child has dysbiosis.

There are many ways to support a developing microbiome. Foundational support should include:

• Daily Fiber Intake. A child who is 4-8 years old requires about 25 grams of fiber daily. Sources of fiber include fruits, vegetables, and legumes.
• Fermented foods: yogurt, kefir, and sauerkraut
• Limiting processed foods and sugars
• Limiting antibiotic use when appropriate
• Ensuring appropriate hydration
• Ensuring restful sleep routines

Probiotics are a great way to help support a developing microbiome. It is important to understand that there are many different strains of probiotics, and each strain is helpful in its own unique way. For example, Bifidobacterium infantis is an important probiotic for infants that thrives off human milk oligosaccharides (HMO’s) from breastmilk. This probiotic is essential to support a developing microbiome and to improve nutrient absorption.

While there are many great probiotic products available, it is important to talk to your provider about your concerns to determine if a probiotic supplement is appropriate.
