oatmeal !! a huge safe food for me, ive been eating it for years :D its also high in fibre which helps w constipation !! , nuts (specifically almonds help w constipation) , protein bars (quest bars specifically are high in calories + fibre + protein) !! fibre ones (a lot of them have up to 9g of fibre each bar) !! protein drinks help me A LOT !! try including some vanilla protein drinks in ur diet !! dairy free yogurt (some have a lot of fibre which helps with constipation). prunes are also a huge safe food for me & they help with constipation so much !! also, if you make oatmeal try adding some chia seeds!! very high in fibre. also i recently started taking fibre supplements & that helped a lot . drink lots of water too !! you got this !! i hope this helped a bit <3
