Hi.
Thanks for your query.
Noted the history about a 40 year old male suffering from
abdominal pain for the last 20 years. On occasions use antibiotics and other medicines as mentioned, there is loss of appetite, weakness for the last 4 months, wants to know whether has gastric ulcer,
H pylori infection, pain increases on intake of milk products and nuts..
This is such a self-explanatory problem as you have mentioned so well.
You look to be allergic/ intolerant to milk, milk products, particularly due to to the
proteins in it and the nuts for the same reasons.
I would advise you the following:
Make a list of the foods and beverages that cause such a problem and stop them altogether and your problem will be solved.
This is called as prevention is better than cure.
There is no specific treatment other than stopping all such products that cause you pain in abdomen.
Keen observation alone helps to find out other products that cause similar problems.
