Hi,
Noted the history of Crohn's, Fodmap diet, low body temperature, reduced bowel movements and
vomiting.
Sickness can be due to deficiency of vitamins, minerals and so on as there is less absorption from the bowel by any disease that causes intestinal problems.
Hence I would advise you to get the complete blood picture including that for vitamins and mineral and get corrected if there any deficiency.
Stress and
anxiety looks to be the major factor that you have get controlled well with or without medications to have best results.
Continue with Fodmap diet if it is helping you.
As for low body temperature the cause can be
hypothermia by the atmosphere around you,
hypothyroidism and any other metabolic disease; please get an opinion of your Doctor for clinical evaluation, examination and necessary investigations to get a proper diagnosis and have a proper management.
Since
diarrhea looks to be under control as well as the nausea continue the management as must have been advised at the moment.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T Chandrakant,
General Surgeon
