Major research findings
Miglitol, an α-glucosidase inhibitor, has been shown to have beneficial effects on blood glucose control in both type 1 and type 2 diabetes patients. In type 1 diabetes patients, miglitol, in combination with intensive insulin therapy, improved HbA1c, glycoalbumin, and 1,5-anhydroglucitol levels, decreased body mass index (BMI), reduced bolus and total insulin dosage, and lowered the frequency of preprandial hypoglycemic events. 3 The study also showed that miglitol increased the active glucagon-like peptide-1 (GLP-1) levels and decreased the total glucose-dependent insulinotropic peptide (GIP) levels. 3 This suggests that miglitol improves blood glucose control by delaying carbohydrate absorption and modifying the incretin responses.
In type 2 diabetes patients, miglitol has been shown to improve postprandial hyperglycemia, reduce circulating levels of the pro-inflammatory cytokine interleukin-18 (IL-18), and potentially reduce the risk of atherosclerosis development. 5 , 4 , 13 Miglitol also demonstrated improvements in glycemic control and insulin sensitivity in obese diabetic rats, suggesting its potential role in managing obesity and related metabolic disorders. 14 Studies on healthy volunteers indicated that miglitol does not have extraintestinal effects on glucose control. 12 This suggests that miglitol primarily acts in the gut to delay carbohydrate absorption.
Benefits and risks
Benefit summary
Miglitol can improve blood glucose control in patients with both type 1 and type 2 diabetes. 3 , 5 , 13 It may also help reduce weight and lower the frequency of hypoglycemic episodes. 3 Additionally, miglitol may slow down the progression of atherosclerosis in diabetic patients. 4
Risk summary
The most common side effects of miglitol are gastrointestinal symptoms such as bloating, flatulence, diarrhea, and cramps. 6 , 16 These are usually mild and tend to subside over time. Miglitol may also have an effect on liver function. 15 Miglitol should not be used by pregnant women.
Comparison across studies
Commonalities across studies
Miglitol has consistently demonstrated its efficacy in improving blood glucose control in both type 1 and type 2 diabetic patients. 3 , 5 , 13 Furthermore, various studies have highlighted its ability to stimulate the secretion of incretin hormones, particularly GLP-1. 3 , 7 , 8
Differences across studies
The effectiveness of miglitol can vary depending on factors such as patient age, weight, type of diabetes, and concurrent medications. 3 , 5 , 13 Some studies have shown a weight-reducing effect with miglitol, 3 while others have observed no impact on weight. 10 Additionally, the timing of miglitol administration (before or after meals) might influence its effectiveness. 1 , 8
Consistency and contradictions in the results
There are some contradictions in the research findings regarding the effects of miglitol. 3 , 5 , 13 , 10 For example, some studies suggest that miglitol can contribute to weight loss, 3 while others indicate no impact on weight. 10 These contradictions likely arise from the varying characteristics of the study populations and the differences in research design and methodologies.
Considerations for real-life application
Miglitol can be a valuable tool for improving blood glucose control, but it’s crucial to be aware of potential side effects. 6 , 16 Always consult with a healthcare professional before starting miglitol treatment. They can determine the appropriate dosage and administration method based on your individual condition. Regular monitoring and adherence to the prescribed dosage are essential while taking miglitol.
Limitations of current research
Research on the effects of miglitol is still ongoing and more studies are needed. 3 , 5 , 13 In particular, the long-term impacts of miglitol use need further investigation. 16 Also, more research is needed to understand the combined effects of miglitol with other diabetes medications. 18 , 9
Future research directions
Further research on the effects of miglitol is warranted. 3 , 5 , 13 Future studies should focus on the long-term effects of miglitol use, the effectiveness of combining it with other diabetes drugs, and its impact on patients with co-existing health conditions. 16 , 18 , 9
Conclusion
Miglitol has been shown to have promising effects in improving blood glucose control. 3 , 5 , 13 However, it’s important to remember that all medications can have side effects. 6 , 16 Always consult with your doctor before starting any new medication, including miglitol, to discuss the potential risks and benefits. Regular monitoring and adherence to the prescribed dosage are essential for achieving the desired outcomes. While miglitol shows promise as a diabetes treatment, further research is necessary to gain a more comprehensive understanding of its long-term impacts and interactions with other medications. 3 , 5 , 13 , 16 , 18 , 9
