Thanks for your question on Healthcare Magic.
I can understand your concern.
Your brother is having alternative
diarrhoea and
constipation.
This is characteristic feature of IBS (
irritable bowel syndrome). Most common cause for IBS is stress and anxiety. He is also having GERD which is also caused by stress and anxiety.
So in my opinion, he should first
consult psychiatrist and get done
counselling sessions.
Try to identify stressor in his life and start working on its solution.
He may need anxiolytic drugs too.
Once his stress, anxiety are controlled his diarrhoea and constipation will also subside.
He should also take librax for IBS.
Don't worry, he will be alright with all these.
Ask him to avoid stress and tension, be relax and calm.
Hope I have solved your query. I will be happy to help you further. Wishing good health to your brother. Thanks.
