My digestive system is slowing down

I had my doctor's follow up check up this afternoon. Since i feel better now, my doctor advised me to stop my medication but i am advised to continue if i feel pain again. This is my problem now because my digestive system is slowing down. I am still hoping that soon will be back to normal. This is usually the problem of old age individuals above 70 years old but i am not yet that too much old, this what makes me worried.
I have to pray more for this.
