Question: I am a 60 year old female with history of acid reflux disease. I take a daily dose of dexilant. The results of a recent endoscopy were good. In the past few days, I have experienced pain originating from the left side of my abdomen and throughout my upper abdomen and back and bowel movement with half-brown and half-black stool. What could be the cause of this?

Detailed Answer:
I read carefully your query and understand your concern.

It is important to clarify if you took Pepto Bismol before or after having black stools.
This because black tarry stools are a serious finding indicating upper gastointestinal bleeding but pepto bismol is known to cause black stools so it is important to know this.
Also is important to know the consistency of your stools.

If your stools were black before using pepto bismol and they were black black (like tar ) not only darker then usually ,then it is a clear sign of upper gastrointestinal bleeding.
If your stool got black after using pepto bismol then it might due to this,but you need to do a stool test to exclude the presence of blood in it.
A stool examination is necessary (fecal occult blood test ) to determine the presence of blood in stool.If this test result positive for the presence of blood in stool you may need to run an upper endoscopy and colonoscopy to determine the cause.

I would suggest to consult your physician and get examined.

Hope my answer has helped.
Let me know if you have any other question or doubt to clarify.I will be happy to assist you further.

Hi, during the past two years there are periods were i get heart palpitations, my left arm starts to hurt and numb and this goes up through the left hand side of my neck as well.. my chest starts to feel heavy, as well as my head. It lasts for about 3-5 minutes, and sometimes the pain in my arm lingers a bit.. it's happened about 5 times in the past 2 years, i think all times it has been after i've eaten something.. i'm not sure if it's serious, or if its just something like acid reflux? would be great to get an opinion...

Hi. I am a 35 years old female. I don't exercise at all, i smoke but very actively working as a sales rep that sees clients at different places. I recently lost 40 pounds dieting alone within a year. Late this year, i experienced acid reflux too. After that, i began having palpitations, breathlessness (occassional and short) and nausea. The nausea one time took me a week getting over. I had ekg done, 78bpm is the result. I had blood tests and urinalysis done, cleared. I am a panicky person and a worrier too. What is wrong with me?
