We explored the effectiveness of magnesium oxide (MgO) as a treatment for chronic constipation using a robust randomized, placebo-controlled trial. Over 28 days, participants received MgO, senna, or a placebo.
Both MgO and senna significantly improved bowel movement frequency and quality of life compared to placebo. About 68.3% of those using MgO reported symptom improvement, showcasing its potential as an effective osmotic agent alongside a stimulant laxative.
Importantly, there were no severe treatment-related side effects reported during the trial.

We explored how changing the frequency of magnesium oxide (MgO) doses influences its effectiveness in relieving constipation. In this study, we looked at 11 patients who had been regularly using MgO to manage their bowel movements and decided to reduce their daily dose frequency over two weeks.
Initially, patients were taking magnesium three times a day, but we reduced this to either two or one dose per day while keeping the total amount the same. We found that the average number of bowel movements dropped from 7.6 to 6.6 in this period. However, this change wasn't statistically significant, indicating that it may not be clinically meaningful.
Additionally, we measured stool consistency using the Bristol Stool Form Scale and noted no significant difference before and after the dosage adjustment. Our findings suggest that reducing the number of doses does not impact the laxative effect of magnesium oxide. This implies that patients can comfortably manage their magnesium intake without sacrificing effectiveness.

Magnesium effectively aids constipation
We investigated how magnesium supplements affect chronic constipation through a systematic review of randomized controlled trials. The analysis included eight studies with a total of 787 participants. We focused on magnesium oxide among other treatment options and assessed its effectiveness in increasing stool frequency and improving consistency.
The findings were quite promising for magnesium oxide. Our results showed that participants who took magnesium experienced a boost in bowel movements, with an average increase of about 3.7 additional movements per week. This improvement in stool consistency was also noteworthy, scoring higher on the Bristol stool chart.
While other supplements like senna and kiwifruit were explored, they didn't significantly enhance symptoms of constipation in this analysis. Therefore, we suggest that magnesium oxide stands out in this study as a worthwhile option for managing chronic constipation. But it’s essential to remember that further research could help confirm these findings and explore the effects of whole food alternatives.

We explored the relationship between magnesium supplementation, defecation, and cognitive performance in elite triathletes. In a carefully designed crossover trial, participants undertook cognitive tests after taking magnesium oxide and after defecation. This study highlighted an interesting potential connection between the state of our digestive system and cognitive abilities.
We found that after magnesium-induced defecation, participants completed cognitive tasks more quickly compared to when they had not defecated. Specifically, the average completion time for the cognitive test dropped significantly after defecation when magnesium was involved. While this suggests that magnesium can aid in relieving constipation, its role in improving overall cognitive function during athletics is also noteworthy.
Although we observed an increase in cognitive performance following magnesium supplementation, it’s important to note that no significant changes in blood flow or oxygen levels were detected in the brain during the test. Instead, we noted decreased oxygen levels in the digestive region, hinting at an increased demand for energy there.
Overall, our findings suggest a potential new avenue for enhancing cognitive function in athletes through magnesium to improve constipation. However, the direct effects of magnesium solely on constipation require further investigation.

Magnesium aids cancer patient care
We conducted a randomized, double-blind trial to assess how magnesium-L-threonate, a new compound, might help relieve constipation while enhancing the pain relief effects of opioids in patients with advanced cancer. During the study, patients receiving this treatment were compared with those taking a placebo, allowing us to clearly see the differences in outcomes.
As the trial progressed, we noticed significant improvements in the group taking magnesium-L-threonate. Notably, this treatment not only helped in managing pain more effectively but also significantly alleviated opioid-induced constipation—a common side effect of opioid use. The data indicated that patients on magnesium-L-threonate required lower doses of opioids for pain management while enjoying better gastrointestinal comfort.
Overall, our findings suggest that magnesium-L-threonate is a promising option in the palliative care landscape for cancer patients, addressing both pain relief and constipation, which can greatly enhance their quality of life.

We examined the effectiveness of oral magnesium sulfate in treating chronic constipation for children with spastic cerebral palsy. In our study, 100 children received either magnesium sulfate or a placebo for one month.
After this period, we noticed significant improvements in bowel movement frequency and stool consistency in the magnesium group, while the placebo group showed minimal change.
This treatment not only alleviated constipation but also reduced the distress of painful bowel movements for both children and their mothers.

Magnesium aids constipation relief
We investigated how magnesium hydroxide syrup affects constipation among patients recovering from acute myocardial infarction in an intensive care unit (ICU). Participants were divided into two groups: one received magnesium hydroxide syrup daily, while the other was given flaxseed powder. Our aim was to determine which treatment better supported bowel movements in these patients.
The findings revealed that magnesium hydroxide syrup indeed plays a role in managing constipation. Patients taking this syrup experienced their first bowel movement significantly sooner, averaging just under 25 hours. Although both treatments increased bowel movement frequency and improved stool consistency, the differences between the two groups were not statistically significant. In other words, while magnesium did help prompt quicker bowel movements, it wasn't drastically better than flaxseed powder in terms of the overall outcomes.
Overall, the study highlights magnesium hydroxide syrup as a viable option for easing constipation for patients in recovery, though its effectiveness is comparable to that of flaxseed powder. The time to the first defecation was notably quicker with magnesium, suggesting its potential utility in clinical settings where prompt relief is crucial.

Calcium effects on constipation assessed
We embarked on a study to understand how calcium, alongside other treatments, impacts drug-induced constipation linked to functional gastrointestinal disorders (FGIDs). Our research involved a double-blind, randomized trial with 168 participants suffering from constipation triggered by medications. Participants were divided into two arms: a placebo group and another group receiving a combination of atorvastatin, atenolol, metformin, amitriptyline, and calcium. Both groups took the treatment for 35 days and were monitored for changes in bowel function and constipation severity.
While the study results indicated that the combination treatment, including calcium, was safe and helped manage constipation symptoms associated with FGIDs, it's essential to note that the study design made it challenging to determine the individual effect of calcium. Although participants experienced improvements, we couldn't isolate how much of that success came solely from calcium, given it was part of a multi-drug regimen. Thus, while calcium appeared effective within the combined treatment, the specific role of calcium alone remains unclear.
Importantly, no significant adverse effects were reported, underscoring the safety of this approach. Overall, we found that while the multi-treatment was beneficial, we still have questions about the exclusive benefits of calcium on its own for constipation.

We aimed to understand how magnesium, particularly when combined with probiotics, influences bowel movements in elderly orthopedic patients suffering from chronic constipation. A retrospective chart review allowed us to analyze various patient records, focusing specifically on the treatments they received and the outcomes.
Magnesium is often talked about as a potential remedy for constipation because it can help draw water into the intestines, making it easier to pass stools. However, since our study also involved probiotics, which can also impact gut health, it becomes harder to isolate the specific effects of magnesium alone.
After reviewing the data, we observed that the combination of magnesium and probiotics did not show a significant advantage in improving bowel movements for the patients involved. This indicates that while magnesium may play a supportive role, its effectiveness on constipation could vary depending on individual circumstances and may not be as pronounced when combined with other treatments.
Overall, this study serves as a reminder of the complexity of managing constipation, especially in the elderly population, where multiple factors can come into play.
