Dysbiosis, Small Intestinal Bacterial Overgrowth, and Irritable Bowel Syndrome are chronic conditions that affect millions of Americans. Maintaining a healthy balance of bacteria which are an essential part of general gut health.

The gut microbiome is home to more than 400 species of bacteria, yeast, and other fungi known as Flora. Flora can be found throughout the human body and is essential to overall gut health. Flora aids digestion, battling pathogenic microorganisms, and producing vitamins.An imbalance of flora in the gut causes bad bacteria to grow uncontrollably. This results in a variety of chronic conditions like Dysbiosis, Small Intestinal Bacterial Overgrowth, and Irritable Bowel Syndrome.

What is Dysbiosis, and What are the Symptoms?

Dysbiosis is a condition where the gut’s flora is imbalanced, resulting in an overloaded amount of bad bacteria. Dysbiosis causes many symptoms of digestive disturbances such as bloating, indigestion, constipation, cramping and diarrhea. Many symptoms associated with Dysbiosis are related to the following other conditions:

  • Inflammatory Bowel Disease (Crohn’s, Celiac, UC)
  • Irritable Bowel Syndrome (IBS) 
  • Allergies
  • Type 2 Diabetes
  • Obesity (over 138 published scientific papers on PubMed on Gut Microbiome and Obesity) 
  • Arthritis/Chronic pain
  • Depression 
  • Plus over 40 diseases, including Cancer.

What is Small Intestinal Bacterial Overgrowth (SIBO)

Small Intestinal Bacterial Overgrowth or SIBO, is Dysbiosis of the small intestine. Naturally, there are much less normal bacteria in the small intestine compared to the large amount in the colon.

In addition, since the small intestine is where absorption takes place, Small Intestinal Bacterial Overgrowth can lead to malabsorption. Above all, this occurs especially in Vitamins A, D, E, K (fat-soluble vitamins), Iron, and Vitamin B12.

What is Irritable Bowel Syndrome (IBS)?

IBS is a common intestinal disorder also known as Irritable Bowel Syndrome. IBS is a highly misunderstood disorder that affects the large intestine and is a chronic disorder that requires long term management. 

What are the Symptoms of SIBO and IBS?

Small Intestinal Bacterial Growth and Irritable Bowel Syndrome are chronic conditions that can lead to a variety of symptoms:

  • bloating and gas
  • diarrhea or constipation
  • abdominal pain
  • nausea
  • fatigue
  • change in bowel movement appearance & frequency
  • mucus in stool

In an extreme case of SIBO/ IBS, the ability to absorb nutrients, resulting in weight loss and anemia. Only a small percentage of people who deal with Irritable Bowel Syndrome experience severe symptoms.  

More likely than not,  it is common for people to have some sort of control over their IBS. This chronic condition can be controlled by regulating their lifestyle by managing their diet and stress levels

What are the Causes of Dysbiosis & SIBO?

Dysbiosis is the result of imbalanced microbiota, leading to an overgrowth of harmful bacteria in the gut. The imbalance of flora can be the result of a variety of factors, including:

  • Constipation
  • Poor stomach acidity (hypochlorhydria)
  • Poor Brain-Gut Connection
  • Proton pump inhibitors/acid reducers (Omeprazole, Pantoprazole, Nexium, Prilosec, Zantac & Tums)
  • Antibiotics
  • Fodmap Foods
  • Food Sensitivities
  • Recent Abdominal Surgery
  • Type 2 Diabetes
  • Open Ileocecal Valve
  • Alcohol
  • Oral Contraceptives

What do Dysbiosis, SIBO, and IBS Tell Us About Gut Health?

 We can learn a lot about gut health when we dive into the complexity of Dysbiosis and Small Intestinal Bacterial Overgrowth. Maintaining a healthy amount of flora is an imperative part of optimal gut health. Studies link Dysbiosis to other gastrointestinal conditions such as IBS, gastritis, peptic ulcer disease, gastric cancer, and colon cancer.Gastrointestinal conditions are among the more common reasons for doctor office visits. Moreover, traditional medicine or gastroenterology, encourage patients that the common solution to these conditions is either to be prescribed medication or undergo surgery. 

 In other words, endoscopies and colonoscopies may rule out life-threatening conditions, but they don’t seek the root function of the             digestive tract. This leaves a lot of unanswered questions to remain.

In the world of functional medicine, testing is done to analyze bodily malfunctions to get to the root of the problem. Body malfunctions including a poor gut microbiome, food sensitivities, gut infections, pH balance, gallbladder function, brain-gut connection, etc.

In many cases, functions are restored by natural therapies. Please request more information on how functional medicine may apply to your specific condition. Contact us at Beyer Natural Health Solutions today.
