If your poop is all liquid, you could have an infection or food allergy
This is watery and like liquid. See your doctor if you have more than three of these a day for longer than two days. Loose stools are concerning because it means you are not getting the vitamins and minerals you need. You will also become dehydrated. Sometimes it’s a result of an antibiotic, because the antibiotic kills the good gut bacteria along with the infection for which it was prescribed.
It also can indicate a food allergy, IBS, or IBD.
Considered: Severe or Acute Diarrhea

Keep this as your "Go to the doctor if..." checklist
Here are the 4 main categories where you should seek guidance from your doctor.
It’s black - Poop is meant to be brown from the bile in your liver that supports the digestion process. While it can be black from minor causes like Pepto Bismol, often it indicates internal bleeding and must be checked.
It’s loose and watery for more than 48 hours - If this occurs, you may have a GI infection or something more serious like UC or Crohn’s disease. It can be also be attributed to less severe circumstances like eating something that didn’t agree with you, stress or a poor diet.
It smells really, really bad - It’s not normally a bed of roses, but there are times when you cringe from your own poop. It can indicate several things, so run it by your doctor:
- Cystic fibrosis - This is sometimes the only noticeable symptom for CF
- Celiac disease
- Chronic pancreatitis
- Malabsorptive disorder
Don’t panic, but be sure you visit with your doctor and rule out anything serious.
There’s blood - Occasionally there is blood because of constipation or hemorrhoids, or mixed in with the menstrual cycle. However, if you have blood inside your poop, there is an issue. It can be damage to the GI tract, chronic illness or infection but more concerning is the possibility of cancer of the intestines, colon, or rectum.
If there’s bleeding, your poop is telling you something loud and clear! Be safe. Get to the doctor’s office, pronto.

Historically speaking, poop has always been connected with health
Wow, who knew? There are people who manage historical archives that include the evolution of poop. And that’s how we know the ancient Egyptians were the first to track bowel movements and the difficulty of constipation. A medical document dated to the 16th century made mention of disease as “a poisoning of the bodies from the inside.” The Egyptians made the link between bad smells and poor health. They documented their belief that to rid disease, a person had to expel it by vomiting or defecating.
By the 1800s the concept of “autointoxication” became a guiding principle of doctors. Concerns over constipation became more relevant with the dawning of the industrial revolution. As people moved less and ate more, poor bowel movements became a significant concern. In fact, constipation became known as the “the disease of civilization.” Constipation was said to be a disease in the gut that caused infections. These infections led to mental illness including anxiety, psychosis, and depression.
The 19th century paved the way for products devoted to helping things along - that is laxatives, colonics, and, for the badly clogged, bowel surgeries. It wasn’t until the the discovery of terms did they realize that diseases wasn’t just caused by the “foul decay of pent-up waste” inside the intestines but by bacteria and viruses.
In 2014, archaeologists uncovered the remains of a huge Roman bathroom, over 2,000 years old. In Rome, public toilets were multi-user affairs — these were long stone benches, lined with 50 holes less than two feet apart — in the city’s underbelly, far beneath its opulent palaces.
