Our GI tract is populated by microorganisms – trillions of them – but antibiotics, highly processed foods, and “bad” bacteria are some sources of damage to the gut’s microbiota. We can feel the effects of a weakened digestive system by abdominal symptoms, such as gut pain and frequent bloating. Other presentations of GI microbiome irregularity such as anxiety, depression, and chronic fatigue may not be as obvious.

People with obesity have high levels of fat, which has the potential to adversely affect health. This fatty tissue accumulation contributes to and may be a result of metabolic dysfunctions. This is why medical doctors and scientists are starting to suggest taking probiotics, as it may support the gut’s metabolic needs.

Probiotics are a blend of living “good” bacteria for the gut. They can be found in food such as yogurt or in OTC capsules. These bacteria strains boost metabolism in numerous ways, including the digestion of carbs, making vitamins (K, B7, B9, B12), and helping our body absorb magnesium, iron, and calcium. Probiotic bacteria also make and send an army of molecules (ex. SCFA) that interact with receptors in the GI tract, assisting with cell communication. By boosting cell to cell interactions, probiotics improve the function of the gut, the brain, and the immune system. The brain is directly connected to the gut by the enteric nervous system, so supporting our microbiome in turn supports our mental health.

When microbial dysbiosis occurs, meaning the healthy ratio of “good” to “bad” bacteria is disrupted, probiotics may be an intervention to alleviate the negative symptoms triggered. It is important to discuss your condition with your doctor, as different strains of bacteria are associated with certain health benefits. It is also recommended to consult with your doctor about starting probiotics even if you are not experiencing any symptoms of bacteria imbalance.

Research-backed strains include:

• Lactobacillus
• Bifidobacterium

Taking probiotic supplements is a step in empowering people with obesity to take charge of their health from within by providing the essential building blocks. As research on the positive effects on probiotics in humans continues, we hope to gain a better understanding of the relationship between our gut and overall health to improve obesity prevention and management strategies.
