Hello Welcome to HCM, thanks for posting your query and I am sorry to hear your medical state.
I read your question completely and have understood it.
Can I know your age?
See these GI, Gastro intestinal problems most of the times are age specific.
But broadly I will try to solve your problem.
We see day in and out about such complaints from patients.
I suggest you these things.
1. Think positive, don't be sad or too worried. I know you feel really horrible but I suggest you to fight back with hard punch.
2. Drink lots of water.
3. Consume a lot of fruit and vegetables. Include in daily diet of yours
4. Avoid meat as much as you can but eat eggs
5. That
Nausea will be usually precipitation of something, find out that and avoid it.
6. Better to start on tablets for a month.
You can take
pantoprazole tablet 40mg daily once morning before breakfast for a month
Hope this will help you.
In case you are more than 50 years old, better to get an
endoscopy done.
Hope this helps you. In case you need any help. Feel free to contact me.
