First of all, speak with your doctor. If you’re taking an opioid for pain, then constipation is likely to happen, and your doctor can help – it’s nothing to be embarrassed about.
Many healthcare professionals use the Rome IV Criteria to help diagnose whether your pain medication is causing opioid induced constipation.1
Your healthcare provider will assess whether you have two or more of the following symptoms1,2:

You have to strain a lot when you try to have a bowel movement

It feels like there might be something blocking your back passage

Your poo becomes very dry and is hard or lumpy (numbers 1 and 2 on the Bristol Stool Chart below)

You have fewer than 3 bowel movements in a week

You feel like you haven’t quite gotten everything out when you go to the toilet
