1. Prolonged Diarrhea
Diarrhea is an abnormal condition that should not last more than a couple of days. If you experience persistent diarrhea that lasts for weeks, it could be a sign that a cancerous tumor is obstructing your bowel. In conjunction with watery stools, other symptoms you should pay close attention to are vomiting, nausea, stomach pains and gas. Persistent diarrhea is a condition that should never be taken lightly. Immediately consult a physician because persistent diarrhea can contribute to dehydration and nutritional deficiencies.
