Many people experience stomach problems from time to time. However, if the symptoms are new or persist, they could be a sign of a serious illness.
These include changes in bowel habits, blood in the stool, very dark or narrow stools, unexplained weight loss, and persistent fatigue, according to the American College of Surgeons, as reported by ScienceDaily.
The organization also notes that rectal pressure, nausea, vomiting, or a loss of appetite may be signs of disease.
These symptoms can have other causes, but they should be evaluated if they continue.

Early examination can make a difference
According to the American College of Surgeons, colorectal cancer screening is recommended from the age of 45 for people at average risk.
People with a family history of colorectal cancer or chronic bowel diseases may need to be screened earlier.
A colonoscopy remains the most reliable method of examination. It allows doctors to detect cancer and remove polyps that could later develop into the disease.
More younger adults are being diagnosed
Although colorectal cancer is still most common among older adults, the disease is now being diagnosed more frequently in younger people.

According to the American Cancer Society, around one in five cases now occurs in people under the age of 54. Thirty years ago, it was about one in ten.
This trend means that colorectal cancer is now the leading cause of cancer-related deaths among people under the age of 50.
For this reason, the American College of Surgeons recommends that persistent symptoms be taken seriously and assessed by a doctor, even before the usual screening age.
