 Hello everyone, there are a few alarming symptoms related to the gastrointestinal tract. Any difficulty in swallowing in the form of food sticking sensation in the throat or in the chest. Any unintentional weight loss of 7 to 8 kilos or more over a span of few weeks to few months. Any presence of blood in the vomitus or any passage of blood or mucus in the stools. Any recent onset of change in bubble habits such as phases of constipation followed by phases of watery stools or vice versa and sometimes the feeling of any lump in the abdomen. So these are the so called red flag symptoms related to the gastrointestinal tract which could be a sign that an individual might be harboring an underlying major gastrointestinal health issue. So any person with the presence of any one of these symptoms should immediately consult a gastro surgeon for a detailed evaluation and to start appropriate management.
