I often have abdominal distension, my stomach is always in a full state, it is very difficult to have a bowel movement, I only go once every 2-3 days, it is very painful when I have to defecate, I feel like I want to go but I can't and I often get sick. headache, nausea but no vomiting. So the doctor asked me what is the cause of abdominal distension and difficulty in defecation?

My mother operated on malignant colon tumor half a month ago. At first, I went to eat porridge for about 4.5 days, then switched to rice, but ate all vegetarian food. About 3 days ago, she ate little and had difficulty defecation. The pain in the abdomen is tingling and then it goes away, the pain lasts a few minutes, but it repeats. So the doctor asked me to eat less with difficult bowel movements after surgery for malignant colon tumor?

With the development of medicine, there are now many methods used to diagnose colon cancer, including colon ultrasound, a non-invasive, painless technique for early detection of colon cancer, helping to make treatment more objective.
