Lactose intolerance following food poisoning

[Sooverthemill]

Anyone had any experience of this? I seem to have very severe food poisoning ( lasting over 2 weeks) and after loads of tests as I’m still suffering gastrointestinal symptoms my GP says she thinks I’ve developed lactose intolerance. But no advice on how long it may last or when I should start feeling better? Ive had no lactose ( reading all the small print) for over 48 hours and still feeling rough. Am I being impatient? Googling suggests it could be up to 2 years. I’ve also cut out wheat on GP advice

Yes, cutting out gluten and dairy would be the first two dietary changes you’d make for SIBO too.

The SIBO (Small Intestinal Bacterial Overgrowth) is what causes the intolerances. Those foods feed the bacteria and the gases the bacteria use cause the symptoms.

The NHS is starting to be aware of SIBO as a condition but the awareness is patchy (only in some specialist Gi departments). It is relatively new scientific research, conducted in the last ten years or so. It usually gets labelled lactose intolerance or post-infectious IBS in the UK. About 70% of cases of IBS have SIBO as the cause.
