As a medical doctor with a focus on integrative health, I often encounter patients struggling with constipation. This common ailment can disrupt daily life, but with the right treatments, relief is possible. In this article, I will discuss two options: macrogol and berberine. Let's explore how they work, their benefits, and why understanding your options is essential.

Understanding root causes first
While both macrogol and berberine can effectively manage constipation symptoms, I always emphasise to my patients that we must look deeper. As an integrative medical doctor, I believe in identifying and treating the underlying causes rather than just managing symptoms.
Common root causes of constipation
- Gut microbiome imbalances: An unhealthy balance of gut bacteria can significantly impact bowel function, and this can be imbalanced by medication, poor diet, lack of sleep etc.
- Food sensitivities: Unidentified food intolerances may contribute to digestive issues.
- Hormonal imbalances: Thyroid problems and other hormonal issues can affect gut motility.
- Structural issues: Physical problems in the digestive tract may need addressing.
- Lifestyle factors: Stress, lack of exercise, and poor diet can all contribute.
The importance of comprehensive evaluation
While using macrogol or berberine can provide welcome relief, I always recommend a thorough medical evaluation to:
- Identify underlying health conditions.
- Check for nutrient deficiencies.
- Assess gut health markers.
- Evaluate lifestyle factors.
- Consider hormone balance.
Creating a comprehensive treatment plan
A complete approach might include:
- Targeted testing to identify root causes.
- Dietary modifications based on individual needs.
- Stress management techniques.
- Appropriate supplementation.
- Lifestyle adjustments.
Key message: While macrogol and berberine can provide effective symptom relief, they should be part of a broader treatment strategy aimed at addressing the underlying causes of your digestive issues. Always work with a qualified healthcare provider to develop a comprehensive treatment plan.

What is macrogol?
Macrogol, also known as polyethylene glycol (PEG), is a widely used laxative that helps relieve constipation. It works by retaining water in the intestines, softening the stool and promoting bowel movements.
How does macrogol work?
Unlike stimulant laxatives that can cause cramping, macrogol is gentle on the digestive system. It draws water into the intestines, which not only softens stool but also facilitates its passage.
The natural alternative: berberine

In addition to macrogol, I have been recommending berberine to patients as a natural alternative. This compound, derived from several plants, has been used in traditional medicine for centuries.
Advanced benefits of berberine: beyond constipation
While this article focuses primarily on digestive health, it's important to note that berberine offers several significant health benefits extending beyond constipation relief:
1. Blood sugar regulation
In my clinical practice, I've observed remarkable effects of berberine on blood sugar levels. Some patients have been able to reduce or discontinue their diabetes medication under careful medical supervision. However, I must emphasise that any changes to diabetes medication should only be made under the guidance of an experienced integrative medical doctor.
2. Cancer support & the Warburg effect
Berberine's potential anti-cancer properties deserve special mention. This natural compound works in part through what scientists call the 'Warburg effect' - a process first discovered by Nobel laureate Otto Warburg:
- The Warburg effect explained: Cancer cells primarily use glucose for energy differently than healthy cells. They consume much more glucose and process it through fermentation, even when oxygen is present.
- Berberine's role:Research suggests that berberine can help interfere with this process by:
- Reducing the ability of cancer cells to take up glucose.
- Activating cellular pathways that help control cell growth.
- Supporting the body's natural defence mechanisms.
In my integrative practice, I've observed how berberine can support patients during their cancer journey through multiple mechanisms:
- Supporting conventional cancer treatments.
- Helping maintain healthy blood sugar levels (important since cancer cells thrive on glucose).
- Providing anti-inflammatory support.
- Potentially interfering with cancer cell metabolism through the Warburg effect.
Important note: This information about berberine's effects on cancer metabolism is based on current research and clinical observations. However, it should never replace conventional cancer treatments. As an integrative medical doctor, I always emphasise that berberine should be used as part of a comprehensive treatment plan, under professional medical supervision.
Optimal dosing strategies
For most adults, I typically recommend:
- Macrogol: 1-3 sachets daily, ideally taken in the morning.
- Berberine: 500-600 mg 2-3 times daily with meals. I love this brand.
Safety considerations
Macrogol is well-studied and considered safe for long-term use. Unlike stimulant laxatives, it does not lead to dependency. Berberine is also regarded as safe but should be used cautiously, particularly for those on medications for diabetes or hypertension.
Managing side effects
Both macrogol and berberine are well-tolerated, though mild side effects can occur. Macrogol may lead to bloating, while berberine might cause initial gastrointestinal discomfort. Staying hydrated is crucial for both treatments to maximise their benefits.
Beyond medication: a holistic approach

Effective constipation management involves more than just medication. Strategies should include:
- Regular exercise.
- Adequate fibre intake.
- Proper hydration (because fibres need to swim).
- Stress management and good sleep.
Addressing dietary habits and stress may also help improve bowel function.
When to seek help
If neither macrogol nor berberine provides adequate relief, further evaluation is necessary. This may involve exploring other treatment options or identifying underlying health issues.
The bottom line
Both macrogol and berberine are effective solutions for managing constipation. While macrogol provides quick relief, berberine offers a holistic approach with additional health benefits. Consulting with a healthcare provider can help tailor an effective treatment plan for your specific needs.
