Olive oil is often considered a natural remedy to relieve constipation, thanks to its potential to promote good digestion and ease bowel movements. Studies, including randomized controlled trials, suggest that consuming olive oil, especially extra virgin olive oil, may help reduce constipation symptoms like hard stools and incomplete evacuation.


This article will explain how olive oil works as a gentle laxative, compare it to other plant oils like flaxseed oil and mineral oil, and provide practical tips for incorporating it into daily use to improve constipation evaluated under Rome III criteria.

Can Olive Oil Be Used as a Laxative?

Olive oil is thought to aid digestion, which may help ease constipation.  =Bile helps the digestive system process food more efficiently, reducing the chance of obstructed defecation and incomplete evacuation. This effect can be especially beneficial for constipated patients struggling with sluggish digestion or infrequent bowel movements.


Olive oil also supports digestion by lubricating the digestive tract. The healthy fats in olive oil coat the intestinal walls, making it easier for stools to pass through. Regular use of extra virgin olive oil may ease constipation symptoms like hard stools and improve overall digestion, offering a natural alternative to treatments like mineral oil or flaxseed oil.

Is Olive Oil Effective for Constipation Relief?

Some studies suggest olive oil may help relieve constipation in certain individuals, particularly in constipated patients who meet Rome III criteria. Randomized controlled trials and studies comparing olive oil to other plant oils, like flaxseed oil and mineral oil, found that olive oil can improve the frequency of bowel movements and soften stools in as little as a few days.


These studies also showed that constipated patients who consumed olive oil experienced fewer symptoms of incomplete evacuation and anorectal obstruction. Its ability to lubricate the intestines and stimulate bile production makes it a valuable option for easing constipation in clinical practice.

How to Use Olive Oil as a Natural Laxative

Using olive oil as a natural laxative is simple and effective. Following the correct dosage, timing, and preparation methods can ease constipation symptoms and improve digestion. Here are practical ways to incorporate olive oil into your routine for gentle relief.

Dosage and Frequency for Safe Use

Taking olive oil in moderation may help constipation while minimizing potential side effects. Start with an initial oil dose of one to two tablespoons per day, which stimulates digestion and promotes a healthy bowel movement. It’s best to use extra virgin olive oil, as it contains the highest levels of healthy fats and nutrients. Daily use is generally safe for most people. Still, those with conditions like kidney disease or those receiving mineral oil treatments should consult their doctor before including olive oil in their routine.

Best Times to Take Olive Oil for Maximum Effect

For the best results, take olive oil on an empty stomach, such as first thing in the morning or before meals. Taking olive oil at specific times may support digestive health and alleviate symptoms of constipation. This simple addition to your routine may improve digestion and ease constipation in the short term and with continued use.

Tips for Mixing Olive Oil with Other Ingredients

Mixing olive oil with lemon juice is a popular home remedy believed to help with constipation. Lemon juice adds a natural dose of vitamin C, which can help soften stools and improve digestion. To use this remedy, combine one to two tablespoons of olive oil with fresh lemon juice and drink it on an empty stomach to reduce constipation symptoms like hard stools or incomplete evacuation.


Another effective option is mixing olive oil with warm water. Warm water helps hydrate the body and soften stools, making it easier for the digestive system to function smoothly. Stir one to two tablespoons of extra virgin olive oil into a cup of warm water and drink this mixture daily to ease constipation and improve bowel movement frequency naturally.

Health Benefits of Olive Oil Beyond Constipation Relief

Olive oil does more than relieve constipation—it’s packed with nutrients that support overall health. From promoting heart health to reducing inflammation, olive oil offers multiple benefits, making it a versatile addition to your diet.

Heart Health Benefits

Olive oil, especially extra virgin olive oil, is rich in monounsaturated fats that are known to support heart health. These healthy fats help reduce bad cholesterol (LDL) levels and improve good cholesterol (HDL), lowering the risk of heart disease. Research suggests that olive oil may support cardiovascular health and improve lipid profiles. Incorporating olive oil into your daily diet may contribute to better cardiovascular health.

Anti-Inflammatory Properties

The antioxidants in olive oil, such as oleocanthal, have powerful anti-inflammatory effects. These compounds can help reduce chronic inflammation, which is a key contributor to conditions like arthritis, diabetes, and even certain cancers. Studies, including those in the World Journal of Health Sciences, show that olive oil contains anti-inflammatory compounds that may help reduce chronic inflammation, making it a natural choice.

Nutrient Absorption Support

Olive oil enhances the absorption of fat-soluble vitamins like A, D, E, and K. Consuming olive oil with nutrient-rich foods ensures that your body fully absorbs these essential vitamins, promoting better overall health. For patients receiving mineral oil or other treatments, olive oil can be a beneficial alternative for improving digestion and maximizing nutrient intake.

Are There Side Effects or Risks of Using Olive Oil as a Laxative?

Olive oil is generally safe to use as a laxative, but it can cause side effects in some individuals. Understanding these risks is important before adding olive oil to your daily routine.


  • Diarrhea and Stomach Upset: Consuming too much olive oil can lead to loose stools or stomach discomfort, especially if taken in large amounts or on an empty stomach. Start with a small initial oil dose to avoid these issues.

  • Allergic Reactions: Although rare, some individuals may experience allergic reactions to olive oil, including skin rashes or digestive irritation.

  • Interference with Medications: Olive oil can interact with medications that lower blood pressure or thin the blood, so it’s essential to consult a doctor if you’re on any prescriptions.

Who Should Avoid Using Olive Oil for Constipation?

While olive oil is safe for most people, some groups should avoid using it as a laxative due to potential risks.


  • Children, Pregnant Women, and People with Certain Conditions: Children and pregnant women should avoid olive oil as a laxative unless advised by a healthcare provider. Individuals with kidney disease or those undergoing dialysis should also use caution.

  • People with Allergies: Anyone with a known allergy to plant oils or olives should avoid consuming olive oil.

  • Patients with Digestive Disorders: Those with conditions like irritable bowel syndrome (IBS) or gallbladder issues may find that olive oil exacerbates their symptoms.

Other Natural Remedies for Constipation Relief

Other natural remedies, in addition to olive oil, can help ease constipation and promote regular digestion. Staying hydrated, eating high-fiber foods, and supporting gut health with probiotics are some of the most effective methods for relieving constipation symptoms.

Hydration and Water Intake

Proper hydration is essential for keeping your digestive system functioning smoothly. Drinking enough water softens stools, making them easier to pass and reducing the risk of obstructed defecation. Dehydration is a common cause of constipation, making it more difficult for stools to move through the intestines.


Aim to drink at least 8 to 10 cups of water daily, and consider warm beverages like lemon water to further support digestion. Hydration combined with remedies like olive oil may support bowel regularity and reduce constipation symptoms.

Foods High in Fiber for Regular Digestion

High-fiber foods are crucial for preventing and relieving constipation, as they add bulk to stools and stimulate the digestive tract. Incorporating these foods into your diet can improve digestion and help relieve symptoms evaluated under Rome III criteria:


  • Prunes: Prunes are a well-known remedy for constipation because they are rich in dietary fiber and contain natural sorbitol, which acts as a mild laxative.

  • Apples: Apples are high in pectin, a soluble fiber that can improve stool consistency and encourage regular bowel movements.

  • Leafy Greens: Vegetables like spinach and kale provide insoluble fiber, which helps move food through the digestive system efficiently.

Probiotics for Digestive Health

Probiotics are beneficial bacteria that support gut health and can help ease constipation by improving the balance of your gut microbiome. Foods like yogurt, kefir, and fermented vegetables contain natural probiotics that promote smoother digestion and reduce constipation symptoms.


Research shows that probiotics can improve Rome III criteria scores for constipation and may be particularly helpful for constipated patients dealing with incomplete evacuation or anorectal obstruction. Regular consumption of probiotic-rich foods is a natural way to maintain digestive health.

When to Seek Medical Advice for Chronic Constipation

Occasional constipation is common, but chronic constipation may require medical attention. If symptoms persist despite natural remedies, it’s essential to consult a healthcare professional to prevent complications.

Signs of Chronic Constipation

Chronic constipation may involve specific symptoms that signal a deeper issue. These include:


  • Less than three bowel movements per week: Infrequent bowel movements can indicate chronic constipation over several weeks.

  • Straining during bowel movements: Difficulty passing stools or the sensation of incomplete evacuation.

  • Hard, dry stools: Stools that are consistently hard and difficult to pass.

When Olive Oil and Other Remedies Aren't Enough

If olive oil and other natural remedies fail to relieve constipation, it may be time to explore other treatment options. Chronic constipation can sometimes result from underlying health conditions, such as irritable bowel syndrome or anorectal obstruction.


Patients experiencing frequent symptoms despite using remedies like plant oils or fiber-rich foods should consult their doctor. Medical professionals may recommend additional tests, medications, or treatments to address the root cause of constipation and improve digestive health.

Is Olive Oil a Good Laxative for Tummy Aches?

Olive oil may be a natural remedy for occasional constipation, thanks to its ability to stimulate bile production and lubricate the digestive tract. Proper hydration, fiber-rich foods, and probiotics can support regular digestion and ease constipation symptoms like hard stools or incomplete evacuation.


However, olive oil should be used in moderation and as part of a balanced diet. If constipation persists despite these efforts, consulting a healthcare provider is essential to rule out underlying issues and find the best treatment plan.
