Hello,Silvia,
Thanks for contacting HCM with your quiery.
I am concerned about your symptoms of watery
diarrhea and presence of lot of blood. This is suggestive
of something acute going on in your abdomen.
You are a little younger to have Acute
Diverticulitis, although
this is a possibility. This may be associated with fever,chills
and
abdominal pain, usually lower abdomen.
Other conditions that I would have to rule out is "Colitis".
It could be
ulcerative colitis or Crohn's colitis.
Crohn's typically affects the small bowel and a portion of
the large bowel. It can affect any part of the intestinal tract
including mouth, esophagus, stomach,small and large bowel.
You also mention taking antibiotics recently. This brings up
possibility of "C.Difficile" infection which can be diagnosed
by testing the stool for Toxins A & B . If present, you need
special treatment. In any case , with the severity of symptoms
I suggest that you contact your doctor as soon as possible.
You may need blood, stool test and a CT-Scan. You may need
a
sigmoidoscopy or a
colonoscopy to rule out colitis.
I wish you the very best.
