What Causes Pink Diarrhoea? How Can You Treat It?


Diarrhoea is a condition in which the stool possesses a distorted colour and shape. Pink diarrhoea is a similar disease in which along with the distortion in the appearance of the stool, there is a pinkish or a reddish colour to it. This colour is due to the fact that the stool contains traces of blood in it. This is a serious condition that is caused by various factors, and must be treated immediately for avoiding further complications in your excretory system. In order to diagnose the condition timely, you must be aware of its causes and symptoms:

Pink Diarrhoea: Causes and Treatment Advice

pink diarrhoea


Irritable bowel syndrome

This one of the leading causes of excretory tract problems. Irritable bowel syndrome is a situation that affects adults and children uniformly. However, it becomes more prominent in adolescence and adulthood. The main symptoms are irregular and watery excretion, abdominal pain, and slightly high temperature.

E.coli infection

This is a bacterium that causes extreme diarrhoea, especially with bloody stool. It takes about 2 to 3 days for the bacterium to start breeding and give rise to the symptoms of the infection, which are bloody stool, acute pain in the stomach, nausea, indigestion, and fever. The major reasons leading to this disease are drinking unpasteurized milk, eating undercooked meat, or consuming too many packaged foods with preservatives.

Anal fissure:

Anal fissure is usually an outcome of piles and vice versa. The skin around the anus tears and leads to blood accumulation. This might lead blood covered stool.


This is commonly called the flu of the stomach or stomach bug. This disease is most common among children of 5 years and below. In this situation, the stomach and the intestines are unnaturally swollen, which leads to irritation in the bowel movement and hence blood stained stool. The most likely symptoms of the infestation of this virus among children are high fever, vomiting, watery excreta, and abdominal pain.

Gastrointestinal bleeding

At times you may face a disorder in your digestive system, which might affect the process of digestion and lead to bloody stool. The major causes leading to this gastrointestinal bleeding, which in turn cause pink diarrhoea are constipation, inflammatory bowel disorder, intestinal diseases, ulcers, and internal haemorrhoids. The constant friction of the stool against the internal walls result in bloody and pinkish stool. Furthermore, the infections cause a diarrhoea-like situation, hence pink diarrhoea.


Cancer polyp

Sometimes there are little growths in your colon, called polyps. These polyps may be a palpable sign of cancer. These tiny growths can get severed at times, due to the passage of stool, resulting in blood-stained excreta.

To get diagnosed in proper time, you must visit the doctor at the slightest inkling of a situation of pink diarrhoea, which entail any or all of these symptoms:

Treatment for Pink Diarrhoea

The treatment process depends on the cause of the disease and the amount of pinkness the stool contains. The cause-based treatments are as follows:

Irritable bowel syndrome:

In such a situation, the doctor usually recommends a series of medication to be followed regularly. The case of irritable bowel syndrome leading to pink diarrhoea is something that even experts have not been able to decode and rectify. Hence, in this situation of pink diarrhoea, it is only the regular medicines that can work on your system to keep it under control.

E.coli and Rotavirus:

Both of these conditions can lead to dehydration that results in hospitalization of the patient. The doctor will most possibly recommend an intravenous injection containing vital rejuvenating fluids to restore the fluid balance of the body. This disease should generally be treated in a week’s time, provided there is ample water intake and timely administration of medicines. When the situation is under control, doctors prescribe some common yet strong over-the-counter medicines like Loperamide to reduce the liquidity of the stool and contain the blood.

Anal fissures or Gastrointestinal bleeding:

Fissures and internal gastric distortions that cause oink diarrhoea are generally treated by recommending the patient(s) to consume high-fiber foods and lots of water or other fluids. If the situation is too severe, the doctor might recommend application of nitroglycerine or lidocaine hydrochloride to reduce the bleeding, burning, and irritation. If this continues for long, the doctor might ask you to run through some internal tests to diagnose the exact cause and then resume appropriate medication for it.


Apart from these treatment procedures, if you feel that there might be a carcinogenic growth inside your system, consult an oncologist immediately, on the recommendation of your present doctor. A timely diagnosis and treatment as suggested by your doctor can save you from further complications.

Pink diarrhoea is not very common, yet not extremely rare and it does occur among children as well as adults. It is vital to know the symptoms, because what may be lightly dismissed as a regular stomach upset might be much more than just that. It is, however, easy to return to your normal bowel functioning soon after proper treatment. So, instead of panicking, rush to the doctor and get yourself examined!
