Thank you for your query,
Nausea,
diarrhoea alternating with
constipation, blood and mucus in stools suggest intestinal pathology.
Would you please clarify a few things for me.
1) how old are you and do you smoke,, have alcohol or other recreational drugs?
2) do you any family members with similar problems?
3) what enzyme level was elevated
4) were you investigated for kidney and liver function.
5) did they check if you were anemic? or check for Tumour markers?
6) when checking for H.Pylori, what test was done?
I would recommend a consult with a gastroenterologist and an
endoscopy /
colonoscopy to directly visualise your intestine to rule out tumour.
Ultrasound will not give you. much information on what is happening inside your bowels.
I would advice you not to wait much longer and see your physician for a gastroenterologist opinion ASAP.
in case of a tumour , early detection and treatment is of key importance to leading a healthy life. if you smoke, stop.( if you find it difficult there is help , just feel free to ask)
hope this helps.
please let us know if you need any clarification.
wish you good health
