Frequently Asked Questions 

Which laxatives are the fastest ones? 

Suppositories and enemas are the fastest laxatives, causing the medicine to be injected directly into the gut. They have a greater risk of side effects, such as stomach cramps and diarrhoea. 

What are the best tricks to immediately empty the bowel? 

The best tricks to immediately empty the bowel are drinking a lot of coffee, squatting while pooping, regularly using fibre supplements, using a stimulant laxative, using a lubricating and osmotic laxative, and using suppositories and stool softeners. 

Describe the 7-step pooping method? 

In this method, it is advised to place the knees higher than the hips and the feet on a stool. Although this rarely helps with constipation, it does make things much easier. 

Is yoghurt a natural constipation reliever? 

Yes, yoghurt is rich in many probiotics that help relieve constipation. However, it is a natural remedy and must not be used as a replacement for treatments. 

What is the quickest method to harden the stool? 

The BRAT diet is very effective for this purpose. It is an acronym for banana, rice, applesauce, and toast. Bananas contain starch, which makes the stool firm by absorbing water. The other ingredients are also effective in various ways. 

How do you quickly relieve the consumption in 30 minutes? 

Rectal treatments, such as suppositories and enemas, are the best ones for this purpose and help improve the symptoms of constipation within 30 minutes. Rectal saline enemas contain sodium phosphate, which helps increase the frequency of visiting the washroom.
