Hi there! It could be bloating that you are experiencing after eating eggs. It is common, I feel bloated too after consuming egg. 1 simple tip- include some carbs in your meal along with the egg protein-like a whole wheat bread toast or chapati along with eggs. Another thing is drink plenty of water through the day. These 2 tips should help decrease the discomfort.
Next Steps
Inspite of this if you are feeling uneasy and having stomach ache, you can avoid eggs. There are other sources of proteins too like pulses, dals, paneer, curds, milk with protinex powder, etc so your growth won't be hindered as such.
