Opioids provide pain relief for people with many conditions, including later-stage cancer. However, these drugs can also have adverse effects, including constipation.
People use opioids to manage severe pain. Opioid-induced constipation (OIC) can cause further discomfort, which can affect a person's quality of life.
However, treatment is often available through natural means or in the form of over-the-counter or prescription medication.
Read on to learn more about the link between opioids and constipation.
Opioids are a medication that are useful for treating severe pain, especially during the later stages of cancer.
They contain substances such as morphine, codeine, oxycodone, and methadone.
Some brand names of these drugs include:
Opioids bind to specific proteins in the body called opioid receptors. These are present in the brain, spinal cord, and gastrointestinal tract.
By binding to these receptors, opioids block the brain's ability to perceive pain.
However, opioids also depress, or slow down, the central nervous system.
The central nervous system is responsible for the pain response, but it also controls the body's movements, including the involuntary movements that make digestion possible.
For this reason, opioid use can result in constipation.

- prostaglandins or prokinetic drugs, which increase the bulk and movement of the stool by changing how the intestines absorb water and electrolytes
