What are Laxatives?

Laxatives are medical products that are used for the treatment of constipation. They work by loosening stools and augmenting bowel movements.

There are various kinds of laxatives that are classified under stimulants, lubricants, and saline laxatives. Each of these functions differently is prescribed for different problems.

The medicine comes in three forms – oral gel capsules, oral liquid and rectal enemas. It takes 12 to 72 hours for oral medications to show results in the body.

Meanwhile, rectal enemas work the fastest. It takes them only around 15 minutes to start functioning. Regardless, each of them is only used for short-term treatment.

Most laxatives should not be used for more than one week. Moreover, they must be taken in moderation.

High doses can lead to problems such as diarrhoea. The medication is safe for people older than 12 years old.

However, a doctor should be consulted before using them for young children. Laxatives do not have any side effects.

However, they work differently according to the body chemistry of a person. Some problems, such as throat irritation, bloating and gas, may occur.

Other mild effects include a fast heart rate, low blood pressure, dizziness, dehydration, and fainting.

What are Stool Softeners?

Stool softeners are laxatives that specifically loosen the stool as part of the treatment for constipation. They add compounds which increase fat-water absorption for easy movement.

People who should avoid using other laxatives that augment bowel movements use these. This is in the case of haemorrhoids, heart conditions and other problems.

These medications are available in the form of tablets, capsules, liquids, and syrups. The appropriate time to use them is before bedtime.

If the problem lasts for a longer amount of time, a doctor must be consulted. Stool softeners have the mildest effects as compared to other laxatives.

And, of course, for the medication. These include a diet of fermented dairy, soups, grains, and various seeds.

Certain changes in lifestyle must also be made to get the best results out of these. For example, one must avoid skipping meals, have enough water throughout the day and exercise.
