Diarrhea, Abdominal Pain, Mucus And Blood In Stools, Membranous Strands. Prescribed Librax. Help
Thanks for writing in.
First and foremost, take a XXXXXXX breath and relax and stop worrying. Let us tackle your problem and I am sure we would find a permanent and stress free solution.
Your symptoms are very similar to IBS (Inflammatory Bowel Syndrome). However, I would disagree with your gastroenterologist. IBS is a diagnosis of exclusion when everything pathological is ruled out. Presence of blood in stool is not seen in IBS.
Weight loss I believe is intentional; however presence of weight loss if unintentional requires evaluation before we label it as IBS.
In addition, the very definition of IBS requires symptoms to be present for at least 3 months with onset of symptoms at least 6 months before the diagnosis. Since you have been having symptoms for only 2 months, this is another reason why I would not label you with IBS.
Therefore, you are right, with blood in stools and lower GI symptoms you are justified in asking for a colonoscopy/sigmoidoscopy. Bring this to the notice of your gastroenterologist and I am sure he would advice a colonoscopy as well.
However, you must remember going for a colonoscopy does not mean you have a colon cancer! Many other conditions can cause similar symptoms- a colon cancer being less likely possibility at your age.
Having said that, presence of small amount of blood in the tissue paper gives a clinical impression of hemorrhoids or an anal fissure. This would be easily picked up even by a GP on per rectal examination. So, I would suggest you undergo a good physical examination first before we go ahead.
You also asked if some parasite can cause these symptoms, the answer is yes and no. Generally, infectious causes are short lasting and they cause symptoms for not more than 1-2 weeks, a prolonged diarrhea due to some bacterial or parasitic infection is possible but rare. If you have not travelled outside your US in recent past, infection with rare exotic parasites or bacteria that cause such prolonged diarrhea is unlikely.
There are some other tests, which I would suggest. They are:
1. Stool culture
2. Ultrasound of abdomen
3. Fecal calprotectin
So in summary discuss the justifications I have given for a colonoscopy with you treating physician. Finally once again XXXXXX, do not worry so much, you will be fine.
Hope I have answered your query. If you have any further questions, I will be happy to help.

Celiac disease is caused by sensitivity to a product called gluten often present in wheat and other cereals like barley and rye. It causes changes in the small intestine which reduces the absorption of nutrients which is hence lost in stool causing diarrhea. It is diagnosed by upper GI endoscopy with a biopsy from your duodenum. There are also some blood tests which can be used for screening for celiac disease.
Inflammatory bowel disease is mainly of two type Crohn's disease and ulcerative colitis. The symptoms include, increase stool frequency, urgency for passing stool and rectal bleeding. Some people also have fever, weight loss etc in severe cases. It is common at a younger age. Ulcerative colitis can be ruled out with a colonoscopy / sigmoidoscopy. The evaluation of Crohn's disease also requires a colonoscopy initially.
Is colonoscopy safe ? well our center we do about 40-50 in a day and we never had any complication ! However any procedure carries certain risk which a doctor would discuss with you before the procedure. Also it is often done under short general anesthesia which also carries certain risk of its own. Since you live away from your parents I would suggest you have a friend or a relative accompany you for the procedure.
Finally it would be helpful to your gastroenterologist if you reveal the entire history the next time when you consult him/her. That would aid in therapeutic decisions.
Hope you have a healthy life.
