Is it bowel cancer that the stool is thick first and then fine

Stool first coarse and then fine is not necessarily intestinal cancer, may be related to eating habits, intestinal diseases, systemic diseases, etc., need comprehensive judgment, if necessary, medical examination. Stool first coarse and then fine is not necessarily intestinal cancer, may be related to a variety of factors. First, eating habits are one of the important factors affecting stool shape. If the recent intake of dietary fiber is insufficient, or the diet is too fine, it may cause the stool to move slower in the intestine, and the water is excessively absorbed, so that the stool becomes dry, hard, and coarse. Secondly, intestinal diseases may also cause the stool shape to change. For example, hemorrhoids, anal fissure, rectal polyps and other anorectal diseases may cause anal stenosis, resulting in poor stool discharge, stool thinning. In addition, ulcerative colitis, Crohn's disease and other intestinal inflammatory diseases may also lead to intestinal mucosa congestion, edema, ulcer formation, thus affecting the passage and shape of stool. In addition, some systemic diseases may also affect intestinal function, resulting in changes in stool shape. For example, diabetes, hypothyroidism and other diseases may cause intestinal motility to slow down, causing constipation or stool shape changes. However, intestinal cancer may also cause stool shape changes, in addition to thick and thin, may also be accompanied by blood in the stool, mucus, abdominal pain, bloating and other symptoms. If these symptoms are present at the same time, or the stool shape changes last for a long time, it is recommended to seek medical attention in time and perform relevant examinations, such as stool occult blood test, colonoscopy, etc., to rule out the possibility of bowel cancer. It should be noted that bowel cancer cannot be diagnosed only by stool shape changes, and other factors may also cause similar symptoms. Therefore, if you are worried about the change of stool shape, you should seek medical attention in time. The doctor will conduct detailed consultation, physical examination and necessary auxiliary examination according to the specific situation to clarify the cause and take corresponding treatment measures. For people over 40 years old, family history of intestinal cancer, long-term smokers and drinkers, obese people, history of intestinal diseases and other high-risk groups, intestinal cancer screening should be carried out regularly, such as stool occult blood test, colonoscopy, etc., so as to early detection, early diagnosis and early treatment. In addition, maintaining a healthy lifestyle, such as a balanced diet, moderate exercise, smoking and alcohol restriction, can also help prevent the occurrence of bowel cancer.
