If intestinal health worsens, it can also negatively affect bowel movements. If diarrhea and constipation continue and become severe, bloody stool may appear.

In most cases, the reason bloody stool occurs is known to be hemorrhoids, but it is said that symptoms can also appear due to various other causes of bloody stool besides hemorrhoids.

Today, I will provide various information about the causes of bloody stool, bright red symptoms, diagnostic methods, treatment methods, and prevention methods.

The causes of bloody stool can also appear due to bleeding from the anus and bleeding inside the intestines. In the case of anal bleeding, hemorrhoids appear as internal hemorrhoids that form above the dentate line inside the anus.

If the color of the bloody stool is not bright red but black or dark red, colorectal cancer, which has symptoms similar to hemorrhoids, may be suspected.

Bleeding that occurs around the upper part of the colon appears in the stool as black or dark red blood. If the bleeding is in the rectum, which is located at the end of the colon, the blood will be even redder.

Because colorectal cancer symptoms differ from person to person, if other symptoms accompany bloody stool, it is important to visit the relevant hospital promptly.

If you are under 40, you can usually suspect the cause of bloody stool to be hemorrhoids, but it may also appear due to inflammatory bowel disease.

Inflammatory bowel disease is a difficult-to-treat condition in which chronic inflammation occurs in the digestive organs among the body's organs. If diarrhea and mucus in the stool accompany bloody stool, an examination should be performed.

Many people mistake bloody stool as just one symptom of hemorrhoids and leave it untreated, but it should not be ignored because it may be a sign of a dangerous disease.

For colorectal cancer, the most dangerous disease, if the stool becomes thinner than usual and blood is attached around the stool, you should promptly receive medical attention.

To diagnose the symptoms more clearly, a colonoscopy is the best test, and it helps detect polyps early.

The large intestine is relatively long compared to other organs, and because its structure is complex, if you are considering a colonoscopy, you should choose a place where medical staff with diverse experience are available.

Even if there are no symptoms, middle-aged and older adults in their 50s or older should undergo regular colonoscopy examinations at least once every five years.

Recently, the age of onset for colorectal cancer has been getting younger and younger, so if you are 45 or older, you should undergo an examination even if no particular symptoms are present.

Since this is a symptom that can occur even at a young age, it is important to respond early with appropriate prevention methods, and it is good to maintain consistent care in daily life.

Rather than building a diet centered on meat and processed foods, frequently consuming fruits and vegetables rich in dietary fiber is helpful.

In addition, you should prevent constipation by drinking enough water, and it is also important to maintain your own regular bowel habits, so please keep this in mind.
