Well in terms of something going horribly wrong, as small a chance as that might be, is one safer than the other? Colonoscopy vs gastroscopy.

Well in terms of something going horribly wrong, as small a chance as that might be, is one safer than the other? Colonoscopy vs gastroscopy.

Both are very safe: modern colonoscopy and EGD are extremely safe. Complications are rare. Probably the most common complication is perforation, and it reportedly occurs in about one of every 1200 colonoscopies and about one every 2000 upper endoscopies. There are rare risks of bleeding and of a reaction to the sedation. Overall, they are extremely safe, and if you have a reason for needing one, don't shy away. ...Read more

Scared.10 lb unintended wght loss.Poor appetite.Cant gain.Many tests.All normal including colonoscopy.Very worried.What can I do?What could be wrong

Many causes for weig: Such weight loss can be caused by benign conditions like hyperactive thyroid(thyrotoxicosis), malabsorption, or emotional disorders like depression. Lastly it could be due to cancer. You need to seek a second opinion unless your first doctor is still pursuing the cause of your weight loss. I would suggest further investigations/tests from an internist who can check you thoughly for likely causes. ...Read more

I read the dosage wrong on the colonoscopy prep. I drank 4 doses in less than 10 mins. Will i be alright?

Yes: The prep is an electrolyte or osmotic solution designed to keep fluid within the bowel wall and cause diarrhea. Taking a dose in a short time will not harm you. Be sure to follow directions about drinking liquids, as you may become dehydrated. ...Read more

Do you know are endoscopys, colonoscopys, cat scans, ultra sounds the only test to show if you have anything wrong?

Do you know are endoscopys, colonoscopys, cat scans, ultra sounds the only test to show if you have anything wrong?

No: Why do you think something is wrong? The first clues are your symptoms. Before ordering tests, a doctor should talk to you about symptoms and do a good physical exam. The tests you mention are all different ways of imaging the body. There are many other tests out there, but nothing as good as a doctor who takes time to listen and think before ordering a bunch of tests! ...Read more

I had a colonoscopy on wednesday & it is now saturday & I am still having stomachaches is something wrong? I have had gas but some is hard to pass...

Colonoscopy problem?: Air used to inflate your colon may persist for several hours--not typically for 5 days. Your post-procedure symptoms may be due to colonoscopy-related factors: colonic or organ mechanical trauma, post-polypectomy syndrome, abdominal wall bruising from external pressure, etc.; diverticular disease; extra-intestinal problems; ibs; lots more. First step--call asap your colonoscopist ; ask his advice. ...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

My stomach bloats up to 5x the size after i eat or drink anything. What could be wrong? Its also really painful. Colonoscopy was normal.

Slow digestion: You may have a problem with your digestive system (stomach) working slower than normal (called gastroparesis) which causes food and liquids to sit in your stomach for longer periods of time. This might be the cause of your bloating and pain. See your gastroenterologist again, perhaps you need an endoscopy or other evaluation of your digestion. Eat and drink small amounts at a time. ...Read more

Normal colonoscopy but blood in stool, what's wrong?

Normal colonoscopy but blood in stool, what's wrong?

See below : The colon is so huge that sometimes the camera doesn't catch a small bleed. Colonoscopies are important to make sure you don't have inflammation in the colon and it rules out serious causes. You might have a blood vessel that bleeds on and off. Or it might be something in the anal area like a crack in the wall causing some bleeding when you wipe. Also the bleed could be from above the colon. ...Read more

In May last colonoscopy which was ok. After that bouts of diarrhea lasting 1week & nothing for 1week.md face me probiotics what is wrong?

Considerations: So, did the diarrhea come back again after not having it for a week? Is it literally every other week? Have you carefully reviewed your diet-any changes? Are you under a lot of stress? Do the probiotics help? Do you have accompanying stomach pain or nausea? You and your doctor may consider a diagnosis of IBS if this continues, especially since your colonoscopy was normal. ...Read more

Not enough: MOM is only used for constipation and is inadequate as a preparation for colonoscopy. You may have been told to take Magnesium Citrate but even this is not usually enough. Call your doctor's office for their recommendation ASAP. ...Read more

Repeat colonoscopy: You have a villus polyp removed for lower GI bleed. It has been 6 weeks and still bleeding. Talk to your GI doctor. This could be a hemorrhoid but it could be another lesion or polyp. It can also be an arterial-venous malformation. Best to have a doctor evaluate. They will also look for anemia. Hope this helps. ...Read more
