Anxiety and Depression in SIBO: The Gut-Brain Connection
SIBO can be an underlying factor in anxiety and depression. SIBO stands for Small Intestinal Bacterial Overgrowth and it occurs when normal gut bacteria overgrow in the small intestine. This can wreak havoc in the gastrointestinal tract leading to malabsorption, inflammation and imbalances in neurotransmitters. Neurotransmitters are chemical messengers in the body that signal many different functions in the body and brain. The most common neurotransmitter in the gut is serotonin. In fact, over 90% of serotonin is found in the gut. So, when the gut lining is compromised in an inflammatory condition like SIBO, that can contribute to anxiety and depression by interfering with serotonin levels in the body. If anxiety and depression are accompanied by digestive symptoms such as bloating, gas, constipation or diarrhea, it is a good idea to test for SIBO. Consult with a Naturopathic Doctor at Arizona Natural Medicine to discuss SIBO testing and how it can play a role in your case.
