Can Laxatives Help You Lose Weight?

Laxatives are medications designed to help the bowels function properly to relieve constipation. However, many people use them in an effort to lose weight. While they can be effective, there are some risks to consider before using them in a weight-loss program.

Laxative Types

There are several types of laxatives:

1. Many foods have a laxative effect, including apples, apple juice, blueberries, coffee, cranberries, olive oil, pineapple, tomatoes, tomato juice, prunes and prune juice. These help to prevent constipation.

2. Bulk-producing laxatives include foods like broccoli or commercial products like Citrucel or Metamucil. These make the stool bulkier and retain water.

3. Stool softeners, such as Colace, Diocto or Ex-Lax, allow oil and water to penetrate the stool and move more easily down the digestive tract.

4. Lubricants, such as mineral oil, are similar to stool softeners; they help the stool to move more easily through the intestines.

5. Hydrating agents, such as Epsom salts and glycerin suppositories, make the intestines take on more water, thus softening the stool.

6. Stimulants, such as Dulcolax and Senna, stimulate the colon's contraction to move stool along.

7. Castor oil alters water and electrolyte secretions in the intestinal mucosa to help flush stool from the intestines.

Healthy Diet

The food-based laxatives listed above are part of a healthy diet and can help dieters lose weight because they help the digestive tract function as it should.

Side Effects

Laxative products can result in cramping, dehydration, diarrhea, fainting, nausea, rectal bleeding and vomiting. They can permanently damage the gastrointestinal tract. Because laxatives stimulate the intestinal nerve endings, eventually these nerve endings will need more stimulants to function, and the intestines will no longer function on their own.

When laxatives are used over long periods of time, bones will weaken, because the large intestine will not absorb the nutrients you need. Laxatives can also affect menstrual cycles and fertility. Over time, prolonged use of laxatives can damage muscle tissues, including the heart, and can even result in death.

Laxatives and Eating Disorders

Those with bulimia or anorexia nervosa may use laxatives to lose weight and then find themselves dependent on them. Because their bodies are no longer getting the nutrients they need, they may have to use laxatives to relieve constipation.

Recommendation

In general, dieters should concentrate on a healthy diet that includes at least five half-cup servings of fruits and vegetables daily. Use laxatives only as needed to relieve occasional constipation. If the constipation continues for more than 1 week, consult a physician. If using an over-the-counter laxative, follow package directions. Do not take more than indicated.
