Are laxatives safe and effective?  What are the risks and benefits of laxatives? These are bigger questions that people worry about.

Types of Laxatives and their usage

It is interesting to note that there are many different types of laxatives. However, they are all associated with digestive tract constipation relief and not with weight loss. Let us look at these types of laxatives:

Bulk-forming laxatives

It is an insoluble fiber that passes undigested through the intestines. As it passes, it absorbed water and bulked up the stool. Drink plenty of water while increasing the laxative intake to keep yourself hydrated. Psyllium (Ispaghula), polycarbophil, methylcellulose, and carboxymethylcellulose are all examples of bulk laxatives.

Osmotic-type laxatives

Effective in promoting frequent bowel movements. It is also capable of retaining more water in the colon. Laxatives of the Osmotic type are used for patients who are unresponsive to bulk laxatives. Examples of osmotic laxatives are saline laxatives, poorly absorbed sugars, and polyethylene glycol.

Stimulant laxatives and Dosage

These stimulant laxatives speed up the bowel movement of the digestive tract.  Unlike other laxatives, stimulant laxatives work within hours of treatment.

The dosage size of the stimulant laxatives behaves differently in the digestive tract.  A lower dosage restricts sodium and water from absorption into the colonic lumen.  A high dosage increases the secretion of water and sodium into the colonic lumen.

Yet, the use of stimulant laxatives is discouraged by people with eating disorders.

Only a single dose is normally recommended because of its fast reaction.  The single dose is primarily for temporary constipation relief.

Examples of stimulant laxatives are: –

  • docusate
  • bile salts
  • phenolphthalein
  • bisacodyl
  • sodium picosulfate
  • castor oil
  • senna
  • cascara sagrada
  • aloe and,
  • rhubarb

Stool softeners

It makes stool get loosened and softer.  It happens by allowing the stool to absorb more water into it. Loosened and softer stool passes through the intestines easily without congestion.

Examples of Stool softeners are docusate calcium (Surfak) and docusate sodium (Colace). Docusate is a laxative. Doctors may prescribe docusate laxatives for constipation.

Lubricant or Emollients laxatives

Lubricant laxatives coat stools and let them pass through the digestive passage easily.  It also coats the walls of the intestines effectively making easier bowel movements.

A good example of a lubricant laxative is mineral oil.

Saline laxatives

Saline laxatives draw more water into the small intestine or small bowel.  This act increases bowel movements

Examples of saline laxatives are:-

  • magnesium preparations (Phillips’® Milk of Magnesia)
  • citrate salts (Royvac®)
  • sulfate salts and,
  • sodium phosphate

Do laxatives help lose weight?

We explained the types of laxatives available above.  You would have noticed and may also be surprised by no mention of weight loss.  The most common point mentioned was only the bowel movement. Because laxatives are bowel movement stimulants only. Not a weight loss solution.

Many people believe taking laxatives is one of the ways of weight loss.  Unfortunately, it is not true according to various studies and research.  Weight loss from laxatives is a temporary effect. It is caused by the loss of water in the body.  The weight loss is the weight of the water loss.

At stimulated bowel movements, the food moves faster in the digestive tract.  So, people tend to think of fewer chances to absorb calories into their bodies. 

But in reality calories and nutrients are already absorbed from the small intestine. Laxatives absorb the water content only.

Hence, taking laxatives gives a feeling of an empty stomach after a meal.  The feeling you get is you are losing weight because of the emptiness.

Actually, there is no weight loss effect but only a weight gain.  You may think that laxatives take care of limiting the calorie absorption factor.

You do lose weight after a regular intake of laxatives because of the absorption of water.  So what you lose is the water weight of your body. As a result, you will continue to lose weight only for a short period of time.  Weight loss may occur up to 2 Kg and then it stops there. Actually, this is no healthy weight loss that you really wanted.

This is really unhealthy and very bad for your health.  Regular intake of laxatives leads to dehydration. You can now imagine the end results. You are inviting unwanted digestive disorders and unwanted other health complications.  Certainly, taking laxatives is not the right thing for weight loss.
