Are Enemas safe for managing my father's constipation at 79?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hi doctor,

My 79-year-old father has Parkinson’s disease and has been severely constipated despite fiber, fluids, and Miralax. He is taking Levodopa, a calcium supplement, and an antidepressant. Could these medications be worsening his constipation? Are Enemas safe for long-term use, or should we consider something like Lubiprostone?

Please suggest.

Hi,

Welcome to icliniq.com.

I understand your concern.

Constipation is a very common and distressing issue in Parkinson’s disease, and you are absolutely right to consider both medications and treatment options. Several factors may be contributing to your father’s constipation.

Parkinson’s itself can slow gut motility due to its effects on the autonomic nervous system. Levodopa may worsen constipation in some patients by further slowing intestinal transit. Calcium supplements are well known to cause hard stools, and antidepressants, especially tricyclics or those with anticholinergic effects, can also exacerbate constipation.

While fiber and fluids are important, they are often not enough in Parkinson’s disease because of reduced colonic motility. Miralax (polyethylene glycol) is a good first-line agent, but it may need to be combined with other treatments for better relief.

Enemas can be used occasionally, but they are not ideal for long-term use because they may lead to dependence and discomfort and do not address the underlying motility issue. Lubiprostone or Linaclotide are prescription medications that increase fluid secretion in the bowel and can be very helpful in chronic constipation, especially in cases related to neurological conditions.

Before making any changes, it is best to review his full medication list with his healthcare provider to identify any other constipating agents. It may also be helpful to consider a referral to a gastroenterologist or a neurologist familiar with Parkinson’s-related gastrointestinal symptoms. Trying Lubiprostone under medical supervision could be a reasonable next step if Miralax alone is not providing adequate relief.

Your attention to your father’s comfort is commendable, and addressing his symptoms can make a meaningful difference in his quality of life.

I hope this has helped you.

Please feel free to reach out to me again for further queries.

Thank you.
