Hello dear,
The symptoms as mentioned in your post can be attributed to accumulation of gas in the stomach, secondary to excess acid formation.
Given the history that you have recently recovered from food
poisoning, this can be considered as recovery process.
Symptomatic relief can be obtained with intake of
Pantoprazole preparation (to be taken twice a day before meals) &
antacid gel (to be taken after meals).
They prevent formation of excess acid in the stomach & provide symptomatic relief.
And it is also needed that you take certain precautions regarding your diet & lifestyle, such as:
1. Take soft, plain, non-spicy foods
2. Drink lots of water to maintain adequate hydration
3. Avoid fast foods & gas producing food products like cabbage, etc.
4. Avoid
smoking & alcohol.
5. Keep away
stress, think positive.
Wishing you a good health.
Take care
