Hi guys, I am new to the forum, although that is not to say that it hasn't provided me with a huge wealth of support, information and help over recent time. For which I am very grateful! I was recently seen by an NHS regarding my GI difficulties and significant weight loss, 13 kg in 12 months. No small amount considering I was already a pretty skinny male as it was. I suffer from an increasing number of food intolerances. Severe bloating and gas, especially following consumption of certain foods. Chronic constipation these past 6 months, whereas it was once reoccurring diarrhoea. I do believe this could be attributed to enforced diet change and consuming less fibre. I am of the opinion that bacterial overgrowth of the small intestine is certainly playing a large part in my issues. I was able to have a Genova 3 day stool test a few months ago. There were a few abnormalities, notably extremely high levels of fecal fat, as well as a few other markers suggesting malabsorption. I discussed SIBO with the NHS gastro consultant I recently visited. He scoffed at the proposition, as my problems are predominantly that of constipation, then SIBO was out of the question he said. I question his thinking here, having read about methane predominant overgrowth. Any opinions on this? Thank you!
