Thank you for your query on Healthcare Magic.
Bloating feeling in the stomach is due to indigestion
which may result from hyperacidity
It is not a symptom due to the removal of spleen.
Avoid spicy food, carbonated beverages, coffee, and tea.
Take meals in small quantity at regular intervals.
If you still feel the bloating, you can take proton pump
inhibitor such as pantoprazole
or omeprazole in prescribed dose.
Hope I have answered your query.
