Why do i get nauseous when i have to poop?

Do you ever feel like throwing up when nature calls? It’s a bizarre phenomenon that perplexes many of us. The urge to defecate is supposed to make us feel relieved, not sick. So why does it happen? In this article, we’ll dive deep into the causes and effects of pooping nausea. Get ready for some toilet humor and scientific jargon!

What Is Nausea?

Before we delve into the specifics of poop-induced queasiness, let’s first define what nausea means. According to medical experts, nausea is a feeling of discomfort in the stomach that often leads to vomiting or retching. It can be caused by various factors such as motion sickness, pregnancy, medication side-effects, dietary issues, stress/anxiety, etc.

Nausea is an evolutionary defense mechanism that helps our body get rid of toxins or harmful substances quickly. By triggering vomiting, our system tries to expel anything that might harm us.

Definition Of Poop Nausea

Now let’s set our focus on why people experience nausea while having bowel movements (poops). Poop-related nauseousness has been coined as defecation syncope, bowel movement fainting, or simply put – poop nausea.

The symptoms usually occur right before or after pooping and may include dizziness/lightheadedness; sweating; pale skin; vision changes; rapid heartbeat/breathing rate/low blood pressure; chest pain/discomfort/tightness; etc., which could escalate into falling unconscious if severe enough!

So what triggers this unpleasant sensation while doing one of the most natural things humans do? Let’s find out.

Causes Of Poop-Induced Nausea

Straining While Sitting On Toilet

One possible explanation for poop-nausea correlation lies in the Vagus nerve. This nerve links our brain stem to most of our internal organs, including the intestines. When we strain to pass a bowel movement, it can stimulate the Vagus nerve which could result in lower blood pressure and heart rate, leading to fainting.

Irritable Bowel Syndrome

Another possible trigger is irritable bowel syndrome (IBS), which affects around 10-15% of adults globally. People who have IBS experience digestive symptoms such as abdominal pain/cramping; bloating/gas; diarrhea/constipation that are often triggered by stress or certain foods/drinks.

Since IBS patients might have an overactive gastrointestinal system due to gut-brain communication issues, it’s plausible that pooping could cause nausea as their gut reacts excessively.

Gastrointestinal Disorders

Gastrointestinal problems like inflammatory bowel disease (IBD), ulcerative colitis or diverticulitis can also induce bowel distress leading up to poop-nausea symptomatology.

Additionally Helicobacter pylori, a type of bacteria commonly found in our stomachs lining may sometimes cause vomiting after meals since it interferes with proper digestion processes resulting in one feeling nauseous (not strictly related but very interesting!).

Medications And Supplements

Certain drugs/supplements prescribed for medical conditions like diabetes/hypertension/depression/migraine headaches etc., can affect how your body functions overall and potential side-effects from them include dizziness and nausea. Hence if you observe sudden unusual nausea while going about your day-to-day routine its advised getting professional help immediately.

Prevention Of Nausea While Pooping

Now let’s talk about prevention methods for getting dizzy on the loo:

  • Don’t force yourself – Wait until you feel comfortable before commencing defecation.
  • Eat fiber-rich food – A diet high in insoluble fiber decreases constipation and the chances of straining while pooping.
  • Stay hydrated – Drink enough water and other fluids throughout the day to stay clear of discomforting effects because of dehydration.
  • Exercise Regularly- Exercises can help you alleviate potential side effects overall, so indulging in it regularly will eventually make you fitter
  • Relax and avoid stress – Practice relaxation techniques like breathing exercises or meditating which has been proven to reduce symptoms like anxiety or IBS.


In short, poop nausea is a real thing that people experience due to various health issues, diet/heredity/metabolism etc., but can often be prevented/copied with optimal care.

So now that you know what might cause this unpleasantness don’t take your digestive system for granted keep working towards being healthy inside out by following good dietary habits/exercise regimes!

And always remember, even if nobody likes discussing bowel movements openly (except maybe doctors!), it’s a critical part of taking care of our bodies; ignoring gastrointestinal disorder indications would only lead to worse outcomes down the line.
