Symptoms of Colorectal Cancer

It is important to remember that very often there are no symptoms of colorectal cancer until the cancer is advanced. This is why it is important to begin and maintain a program of regular screening as recommended by your doctor. Common symptoms of colorectal cancer include:

  • Change in bowel habits
  • Blood, either bright red, or black and tarry, in the stool
  • Stools that are narrower than usual
  • Diarrhea, constipation, or feeling that the bowel does not empty completely
  • General abdominal discomfort, such as frequent gas pains, bloating, fullness, and/or cramps
  • Unexplained weight loss
  • Constant feeling of fatigue or tiredness

Water Before Meals May Promote Weight Loss
August 2015

A randomized trial found that drinking water before main meals led to higher weight loss than those who were asked to imagine a full stomach before main meals. Water preloading is believed to help create a feeling of fullness or satiety during the meal, which may help curb overeating.
