Is chronic constipation (daily miralax, (polyethylene glycol) frequent senna, glyc. Supp's aren't enough. Enemas needed often) in 
toddlers considered a Motility issue?

Stool retention: This is more an accident than a motility issue. When/if the kid decides one day not to poop, and the next day has a hard painful stool, they may try to stop having them. Over time stool retention causes physical changes in the large bowel causing poor emptying. Parents try short treatments that fail & the problem continues. This often requires a developmental ped or pedi GI working for a year . ...Read more

Is using Glycerin Suppositories chronically bad? I have chronic idiopathic constipation.

From Above: A better overall strategy is to help constipation " from above" so to speak. Increased fluids, vegetables, salad, perhaps a daily spoonful of metamucil are all helpful. Add in a daily dose of Miralax (polyethylene glycol) or mineral oil and you should be able to have soft daily stools. Using glycerin suppository is safe, however, if the above strategies aren't helping. ...Read more

Can I use colace as a miralax (polyethylene glycol) replacement every day for chronic constipation?

Up to your doctor: Talking with your own doctor about this will yield more personalized results -- it looks like you've had quite an extensive workup of your GI complaints. Being on chronic laxatives is likely to be unhealthy for you in the long run. Colace (docusate sodium) is a stool softener, not a laxative -- but some say it causes cramping. Hoping you and your doctor can arrive at a helpful plan. ...Read more

Can miralax (polyethylene glycol) cause pencil thin stool?

Can miralax (polyethylene glycol) cause pencil thin stool?

Comcermnng: Miralax (polyethylene glycol) and other agents used for constipation should not cause pencil thin stools. I am concerned that you are requiring daily constipation medications. You need to see a gastroenterologist who then may proceed with a colonoscopy to make sure you have nothing in your colon that is causing the thin stool and you then need to discuss the issue of constipation. Please proceed with the GI physician ...Read more

Suffer from chronic constipation. I have hypothyroid. My gastro md says its that. Md recommends miiralax up to 4x a day. I drink a lot  of water & exe?

A lot of Miralax (polyethylene glycol): After being on thyroid replacement recheck blood level of TSH (thyroid stimulating hormone)-takes about 3 weeks to change. Meanwhile, check diet-adquate fiber foods like beans, whole grains, fruits, vegs, fluids, activity. Check meds, otc, supplements, e.g. Calcium can be constipating. Get enough oil in diet. Age? May need colonoscopy to check things ok inside. Miralax is safe, but 4x/d is a lot. ...Read more
