White Sesame in Stool: Is It a Sign of Parasites or Something Else?

Is the presence of white sesame seeds in stool a sign of parasites?

Hello Doctor, I have been experiencing pain in my left middle, middle, right middle, lower middle, right lower, and left lower abdomen (using the navel as a reference) since mid-July.
I started receiving treatment from a physician in October, who diagnosed me with irritable bowel syndrome and excessive gastric acid.
Currently, I have been taking medication: OTilonium 40mg (once) + Nizatidine 150mg (once) for 14 days (morning and evening), followed by blood tests, stool tests, and X-rays.
After 14 days, I was prescribed Esomeprazole TAB 40mg (once) for 14 days (evening).
The previous test results seemed normal.
After another 14 days, I was given Iwell (once) for 7 days (morning, noon, and evening) and had blood tests again.
After 7 days, I continued with Iwell (once) for another 7 days (morning, noon, and evening).
The report indicated abnormal bilirubin levels, and an ultrasound was scheduled for the next day.
The following day, the ultrasound examination determined "constitutional jaundice," and I was prescribed Iwell (once) for 21 days.
After 6 days of taking Iwell, my gastric acid issue has mostly resolved, but I still occasionally experience pain in the left lower abdomen.
Theoretically, after completing the 21 days of Iwell, if there are no issues, I should not need to return for a follow-up.
However, today I noticed very distinct and complete white sesame seeds in my stool, leading me to suspect a parasitic infection.
In early September, I experienced anal itching for a few days, but after thoroughly cleaning, it resolved.

In the image: https://www.dropbox.com/s/6gdwv8hdjewgzis/photo_2019-11-21_23-34-55.jpg?dl=0, the red area shows that I have not eaten white sesame seeds recently (and they are not this large...), so it should not be digested food.
I suspect it might be a parasite.
Regarding the blue area, this has been a consistent issue with my stool over the past few months, showing strange white edges.
The structure is not very solid, and some parts break off when submerged in water; sometimes there is more, sometimes less.
This time (in the image) seems to have more; a week ago, only 1/10 had this white substance.
However, when I was healthy before, I did not have this.
I would like to ask if this could be a parasite? As for the blue area, could this be gastrointestinal mucosa? Is there any harm?

More Info

The presence of white sesame-like particles in your stool can indeed be concerning, especially given your history of gastrointestinal issues and abdominal pain. While it is understandable to worry about the possibility of parasites, there are several factors to consider before jumping to conclusions.

Firstly, the appearance of white sesame seeds in your stool could be due to a variety of reasons. One possibility is that these particles are undigested food remnants. Certain foods, particularly those high in fiber or with tough outer shells, can sometimes pass through the digestive system without being fully broken down. If you have recently consumed foods that resemble these particles, it might explain their presence in your stool.

However, given your concern about parasites, it is essential to consider the symptoms associated with parasitic infections. Common signs of parasitic infections include abdominal pain, diarrhea, changes in appetite, weight loss, and sometimes itching around the anus. You mentioned experiencing anal itching in September, which could suggest a possible parasitic infection, such as pinworms. Pinworms are small, white, and can sometimes be seen in stool. They are more common in children but can affect adults as well.

In your case, the fact that you have been experiencing abdominal pain and have undergone various tests, including blood tests and imaging, suggests that you are already under medical care. It is crucial to communicate your findings, including the appearance of these white particles, to your healthcare provider. They may recommend a stool test to check for the presence of parasites or other abnormalities.

Regarding the blue area you mentioned, which has been a consistent feature in your stool, it is essential to have this evaluated by a healthcare professional. Changes in stool consistency, color, or the presence of unusual particles can indicate underlying gastrointestinal issues, including inflammation or irritation of the intestinal lining. This could be linked to your diagnosis of irritable bowel syndrome (IBS) or other gastrointestinal conditions.

In summary, while the appearance of white sesame-like particles in your stool can be alarming, it is essential to consider all potential causes, including dietary factors and the possibility of parasitic infections. Given your ongoing abdominal pain and previous symptoms, it is advisable to follow up with your healthcare provider for further evaluation. They may recommend stool testing or other diagnostic procedures to determine the cause of these symptoms and to ensure that any potential issues are addressed promptly. Always prioritize open communication with your healthcare team to ensure the best possible care for your gastrointestinal health.
