My 6 mo has unilateral renal agenesis and grade 4 reflux causing Hydrouereteronephrosis. Is antibiotic prophylaxis necessary in his case?

C diff for about 3 months.found out last month and neither 2 antibiotics worked.now my gi wants a colonoscopy.how will this help? What can show up?

Diagnostic: It sounds like you might have been left with unexplained symptoms. It is not usual for C diff not to respond to Flagyl and/or Vanco. Colonoscopy is needed most likely in order to visualize macroscopic changes and/ or to rule out colitis as the possible cause for your symptoms. Biopsies might be taken during the procedure. Protracted symptoms are seen in treated C diff colitis. ...Read more

What can cause mucus in stool? Had normal colonoscopy one year ago. HadC Diff almost 2 yrs ago. Have not had antibiotics in almost 2 yrs. Am I ok?

Mucus in stools: Small amounts of mucus in stool is often unremarkablet. Stool often contains small amounts of mucus (a jelly-like material that your intestines make to keep the lining of your colon moist and lubricated). However, if you notice an increased amount of mucus in stool associated with blood or a change in bowel habits, then this deserves further investigation. ...Read more

If a child is diagnosed with scarlet fever, will the family members receive antibiotics as prophylaxis?

If a child is diagnosed with scarlet fever, will the family members receive antibiotics as prophylaxis?

Not necessarily: This disease is caused by the organism which causes strep throat and many family members may be carrying this in the back of their throats without symptoms. There are some doctors who may favor prophylactic treatment, but it does not have a high success rate in eradication of these bacteria. It is a judgement call by the doctor. ...Read more

Can a colonoscopy be performed if you are on antibiotics or have a cough? (being intubated for procedure). No fever & chest xray was clear.

Can a colonoscopy be performed if you are on antibiotics or have a cough? (being intubated for procedure). No fever & chest xray was clear.

Yes: If you have no fever, a normal chest x-ray and no wheezing, chances are you'll be fine. However, if you aren't feeling well, you may want to put it off.
Why do you need to be intubated? Most colonoscopies are done with some form of twilight anesthesia. It is unusual to require an intubation. Knowing why may lead me to a different conclusion than the one above. ...Read more

Get 2nd opinion: If these measures failed and you have been avoiding lactose (milk), one needs to consider other potential causes. Have you tried a low FODMAP diet? Where does the pain come from? If at the right upper quadrant, needs to consider a gallbladder disorder. ...Read more

Are prophalaxis antibiotic stil regularly used for bronchiectasis?does recent evidence suggest not to use them anymore, or is this false infor I got?

Sometimes: Largely depends on the underlying cause of bronchiectasis and sometimes on individual physician experience/preference (since there aren't good large research studies supporting or not supporting the effectiveness). Generally, especially if recurrent infections or persistent sputum production, some form of suppressive antibiotic is used. A real problem involves colonization with resistant microbes ...Read more

Why can’t I have red jello before my colonoscopy? My doctor said any clear liquid is fine, and red jello is clear. So what’s wrong with it?

Why can’t I have red jello before my colonoscopy? My doctor said any clear liquid is fine, and red jello is clear. So what’s wrong with it?

Red : Red (and purple) jell-o and other clear liquids with these colors can look like blood in the colon and also absorb the same wave length light that is needed to highlight the sometimes subtle color differences in the colon that we need to see in order to identify the pre-cancerous polyps that we are looking for when performing colonoscopy. It can make it more difficult to see these polyps, increasing the chances that something is missed. ...Read more

How often should a man in his late 50s have a colonoscopy? I'm prescribed omeprazole as the first one found one benign polyp deemed adenomatous

How often should a man in his late 50s have a colonoscopy? I'm prescribed omeprazole as the first one found one benign polyp deemed adenomatous

Depends on risks: For those at low risk for colorectal polyps/cancer (no personal or family history of polyps/cancer, no other risks), every ten years if no adenomatous polyps are found. If polyps are found, the interval is shorter: every five years is usual unless polyps are large or multiple. Btw, Omeprazole inhibited polyps in rats; the same has not been found in humans, but Omeprazole can cause gastric polyps! ...Read more

Due to acute left side abdom pain no food in over a wk.(doc thinks bowel inflamed). Will effects of no food show up in colonoscopy?(mask s/ thing else)

Not typically: Depending on age, lower left sided abdominal pain may be an indication of diverticulitis. This might be the " inflamed bowel" you are referring to. Putting the bowel at rest with clear liquids initially, and antibiotics usually helps. A. Ct scan of the abdomen/pelvis can help make the diagnosis. After you feel better, and the infection resolves, a colonoscopy is indicated to further evaluate the colon. ...Read more

Why do ikeep getting stomache cramp in day but not at night had a colonoscopy 2 years ago all perfect could it be i.b.s had for 2 months no blood i po?

Why do ikeep getting stomache cramp in day but not at night had a colonoscopy 2 years ago all perfect could it be i.b.s had for 2 months no blood i po?

Could be one of many: One of several causes.
IBS will not cause pain as a main symptom. It is associated with alternating constipation and diarrhea. The pain medicines that you are taking like tramadol can cause abdominal cramps, so try stopping your pain medicines other than Tylenol(which is safe to take if needed). Go see your doctor and try an antispasmodic medication prescribed by your doctor. Bentyl (dicyclomine) is one such me ...Read more

What’s the difference between a colonoscopy and a sigmoidoscopy? I had a sigmoidoscopy that was negative. Now my doctor wants to do a colonoscopy. Why? What’s the difference?

Length: Sigmoidoscopy only allows for part of the colon to be visualized and generally does not involve sedation medications. Colonoscopy is intended to visualize the entire colon and often requires sedation medication. ...Read more
