Diarrhea After Constipation: Is It Normal?

Most of us can relate to experiencing an upset stomach that can lead to diarrhea or constipation. This is a common occurence and is usually not a cause for concern as it goes away after some time. But is it normal to have diarrhea after constipation?

Could this be a sign of more serious conditions, such as IBS (irritable bowel syndrome), or ulcerative colitis? Read on to learn more.

Why does diarrhea happen after constipation?

Diarrhea happens after constipation due to a blockage in the bowel of a person (severe constipation).

Due to this blockage, the bowel may start to leak out stools that are watery. Then, the watery stool will pass around the blockage and out of the rectum. 

This excess watery stool is called overflow diarrhea. This term was coined for those who experience watery stool not exactly related to diarrhea.

People must not take any anti-diarrhea medications if they have overflow diarrhea. Instead, they must consult their doctor to find out if they should take any specific medication to safely treat their condition.

So is it normal to have diarrhea after constipation?

Yes, diarrhea after (severe) constipation is normal. This condition is not uncommon. Overflow diarrhea may go away after some time – usually after about a week – so it is not a cause for concern.

To ease the discomfort, they can consult their doctor and ask what medications they can safely take. 

The only instance where diarrhea can be a problem after constipation is if a person starts to exhibit the following symptoms: 

• Diarrhea with blood or pus
• Pain in the abdominal region and cramping 
• Rectal bleeding (the stool has small amounts of blood) 
• Urgent need to defecate
• Fatigue
• Fever
• Weight loss 
• Inability to defecate despite the urgency
• In children, stunted growth

If a person starts to experience these symptoms, they must go to the hospital immediately and have themselves checked. This condition is a much severe one, as it is indicative of ulcerative colitis. Although this condition is not usually fatal, there are several risks and complications that are deemed life-threatening for others. 

How can diarrhea after constipation be addressed? 

More often than not, diarrhea will go away after a few days even without any medication or any form of treatment.

However, the moment it does not go away and persists to be, people can consult with their doctor and ask for medications. Doctors can give anti-diarrhea medicines if they are deemed safe. If not, then other treatments may be given. 

Doctors may also ask for a stool sample to find out what has been causing frequent diarrhea.

Always remember to consult a doctor before taking any anti-diarrhea medication as this may worsen things rather than alleviate diarrhea. 

Diarrhea may lead to dehydration, so ensure sufficient fluid intake. Do not force yourself to eat solid foods, only do so once you are able. Also, start consuming small amounts of food and avoid heavy meals, spicy, and fatty foods. 

Other treatments would include: 

• Antibiotics 
• Medication adjustment 
• Replacing fluids. If drinking fluids upsets the stomach, then the fluids would have to be replaced with IV fluids. 
• Drink fluids that contain electrolytes and minerals such as potassium and sodium (fruit juices and broth). However, some fruit juices should be avoided as they may worsen diarrhea, for instance, apple juice. 

When should you see a doctor?

A person must go to a doctor once they experience unusual symptoms of diarrhea. Such alarming symptoms would be stool with bleeding and rectal bleeding. Also, if a person starts to feel pain and cramping in their abdominal region, then they must go see a doctor as soon as possible.
