best natural laxatives for weight loss

Overweight people often have a tendency of eating junk food as a result of which many suffer from dry, hard stools and chronic constipation. Years and years of these poor dietary habits clog up the colon and intestines. As the individual continues to pile junk food, she/he chokes up the elimination system.

Sometimes even if you eat healthy food and lots of green vegetables loosing weight just might not be that easy.

Do Laxatives Help You Lose Weight?

Irregular bowel movements can lead to bloating and weight gain around the stomach area. Since many of these people do not have a bowel movement regularly, they tend to feel lethargic. Lethargy and constant fatigue lead to inactivity and subsequent weight gain.

This becomes a vicious cycle wherein the person has no energy, feels tired and hungry all the time and is unable to clear up the digestive system. His/her body also fails to absorb nutrients from the food leading to further debility and malnutrition.

Sometimes, even those who are seemingly not overweight can suffer from constipation and that can occur for many reasons including pregnancy, some medications or simply stress.

Using laxatives to lose weight is very common. A laxative or stool softener can help in such cases. Laxatives speed up the process of elimination of solid waste from the bowels and clear up the clogged colon and intestines. Not only does this result in detoxification; it also leads to a bit of weight loss.

In this guide, I will be talking about everything one needs to know about laxative usage and the best brands of laxatives that are suitable for weight loss and regularity.

What Are Laxatives? How Do They Work?

Laxatives are medicines which prevent and treat constipation by softening the stool or stimulating the intestines to push out stools. Most herbal laxatives contain anthraquinones which stimulate the colon to contract frequently and cause secretion of electrolytes and water into the intestines. This pushes out material from the intestines faster.

Do Laxatives Aid in Weight Loss?

Some types of laxatives have a diuretic action - they expel water out of the body. They also speed up the process of expelling waste from the body. Since the body loses both solids and water, there is a bit of weight loss.

It is important to note that this weight loss is in fact only a water loss. There is no loss in body fat. Also, laxatives do not stop your body from absorbing calories from food. So, if you are only using laxative weight loss teas for losing weight, you will likely be disappointed.

You must eat healthily and exercise regularly to lose weight. However, weight loss laxative teas are great remedies for jumpstarting sluggish colon.

They especially work great after you have binged on food during holidays or celebrations. Studies have shown that laxatives can rid your body of nearly 12% of the calories absorbed. Constipation also results in bloated, puffy look which can be eliminated by using laxatives safely.

Different Kinds of Laxatives

Commercially, many different kinds of laxatives are available. The common ones are:

Stimulant Laxatives

These include senna, castor oil, bisacodyl, cascara sagrada etc. Many like phenolphthalein are dangerous and yet pharmaceutical companies make them available over the counter without prescription.

Bulimics often abuse these type of laxatives to lose weight and purge after eating. They work by stimulating nerves of the large intestines to cause contractions. These push of water and solids resulting in bowel movement.

Overuse of such laxatives can lead to electrolyte imbalance. Also, over time, people develop tolerance to them so they need higher and higher doses each time. These laxatives tend to be habit-forming.

Osmotic Laxatives

These are laxatives like Epsom salts, milk of magnesia etc. They work by drawing water into the intestines. Compared to stimulant laxatives, these are non-habit forming. Some of these medicines do require prescription. Also, overuse can still cause health issues like dehydration, electrolyte imbalance etc.

Lubricant or Emollient Laxatives

These are generally safer than most kinds of laxatives as long as you use them for limited periods. They work by softening the stool. Common examples are mineral oil, castor oil and docusate.

Bulk Forming Laxatives

These are the safest types of laxatives as they add fibre to the intestines and increase roughage which pushes the faeces out easily. Main examples are psyllium in brand names like Metamucil. However, you must take it only as directed as overuse can cause intestinal problems and even prevent absorption of nutrients.

How Long Does it Take for Laxative to Work?

How long laxatives take to work depends on many factors:

  • How sensitised you are to them. With long-term use, you could develop tolerance thereby needing more quantity or taking longer for the medicine to work.
  • Your body weight
  • The type of food you have eaten
  • Kind of laxative you are using.

Advantages of Laxatives

When used as directed, laxatives can have many positive benefits:

  • Laxatives treat constipation which is a cause of a wide range of health issues including skin problems, indigestion, flatulence, etc.
  • They result in weight loss by removing clogged up matter and preventing constipation. Laxatives clean out the colon and help in detoxification.
  • Certain laxatives like Psyllium benefit heart health. A study has shown that 10 grams of psyllium providing 7grams of fibre per day reduced total cholesterol by 5% and LDL cholesterol by 9%.
  • Certain types like castor oil are generally safe for use in constipated babies.
  • Elderly patients and those needing palliative care can definitely benefit from safe use of laxatives.

Dangers of Laxative Abuse

Large amounts of laxatives can cause many health issues. They should never be used for prolonged periods of time. Dietary changes like eating fibre rich foods can help you overcome constipation. Likewise, for weight loss, you need to follow a balanced diet with regular exercise.

Following are some side effects and dangers of laxative abuse:


Yes, prolonged use of laxatives can lead to impaired intestinal function as a result of which, they lose their ability to move the stool out. Dependency on laxatives can also cause patients to take higher and higher doses.

Fluid loss

Loss of water from intestines can cause dehydration. Symptoms include dizziness, fainting, extreme thirst, headache, decreased urination, dry mouth etc.

Electrolyte imbalance

With certain laxatives, there is an imbalance of sodium, potassium and chloride. This can cause irregular heartbeat, weakness and even heart related issues. Sometimes, severe diarrhoea can result from excess intake of laxatives causing death.

Bloody stools

Laxatives can irritate the colon and intestines leading to bloody diarrhoea. With prolonged bleeding, one could experience fatigue, anaemia, weakness and general debility.

Rectal prolapse

In very severe cases of laxative abuse, the intestines can protrude out of the rectal opening. This condition needs surgery and is very painful.

How to Choose a Laxative

Laxatives are available in form of tablets, capsules, oils, powders or teas. Whatever product or type you choose, take it only as directed by your healthcare practitioner.

If you are taking pills or powder, take it with a tall glass of water. You can take the pill orally with or without food. Night time is best so that you have a bowel movement the next morning. The downside to taking laxatives at night is that you could wake up from cramps or having to go at night.

While taking powders mix the required quantity with a glass of water. In any case, no matter what type of laxative you use, it is advisable to drink tons of water to prevent electrolyte and fluid imbalance. Castor oil and mineral oil work quite quickly; in 5-6 hours you will have a bowel movement. Avoid taking castor oil at bedtime. Never take laxatives after taking antacids or milk.

Choose a laxative based on the goals you wish to achieve.

  • For mild constipation, choose bulk laxatives or saline agents like milk of magnesia.
  • In case of severely constipated bedridden patients, you might need enema in addition to laxatives.
  • If the first line of treatment does not work, you may consider changing the type of laxative.
  • Read labels carefully. Many products are advertised as “New Improved Formula”. So a good old stool softener may now contain laxatives like senna which you may not want. Always talk to a pharmacist prior to selecting a laxative.
  • Many bulk-forming laxatives contain sweeteners which can affect your blood sugar levels. So choose wisely. Several bulk-forming laxatives are known to cause bloating, abdominal cramps etc.
  • Some fibre laxatives are also available in the form of cookies. Many people tend to eat a lot of wafer/cookies laxatives. Note that these contain fat and sugar and, in excess, can lead to diarrhoea, bloating and cramps.
  • In senior patients with constipation, one must select laxatives based on age, urinary as well as the cause of constipation.

What Causes Constipation?

Constipation is usually caused by a disorder of bowel function rather than a structural problem. Common causes of constipation include:

  • Inadequate water intake
  • Not enough fibre in the diet
  • A disruption of regular diet or routine e.g. travelling
  • Eating large amounts of dairy products
  • Stress and inadequate activity or exercise 
  • Immobility due to sickness
  • Laxative overuse which, over time, can weaken the bowel muscles
  • Hypothyroidism
  • Neurological conditions such as Parkinson's disease or multiple sclerosis
  • Using antacids containing calcium or aluminum for a long time
  • Medicines and supplements, such as narcotics, antidepressants, or iron pills
  • Depression and eating disorders
  • Resisting the urge to have a bowel movemen
  • Pregnancy

Chronic constipation can be an annoyance at the least and could also indicate serious underlying health issues at the worst. Moreover, it leads to weight gain, inactivity, lethargy and bloating.

Laxatives provide a safe way of moving the bowels. Using a colon cleansing supplement can help improve your gastrointestinal health on several fronts. The laxative effect in colon cleansing supplements can treat constipation, helping to prevent toxins from sitting around in your colon and causing damage.

However, it is important not to abuse laxatives for weight loss or weight management. Many people are under the impression that if the bowels do not move daily, they are not normal.This is not true.

Do consider all these factors when selecting laxatives for weight loss or general regularity. To repopulate the healthy gut bacteria in your gastrointestinal tract, look for a colon cleanse that has probiotics, or take a separate probiotic supplement.

I hope the above reviews of best laxatives help you make the right choice.
