Detailed Answer:
Brief Ans-Assessment of Scheduled Colonoscopy/ Under Evaluation

My Impression of your health problem-
-Need for Colonoscopy- is planned mostly to see if the colonic growth is causing any Colonic Obstruction and leading to bloated stomach with right back pain in your case.
-With existing health status -possibility of the partial adhesive obstructions from multiple major operations in the past,is the explanation for your Right Back pain with stomach bloatedness.
-The fatigue is due to the Mal-absorption Syndrome from repeated partial adhesive bowel obstructions

Hi,Dear,thanks for your query to HCM.
Dear,I Read and reviewed your query in context of scheduled colonoscopy related to unexplained health issues of right side back pain with breath shortness/ with fatigue / nausea / with sleeplessness due to it.

Dear,the God has been kind to you that you are 5+Colon Cancer,meaning almost on verge of Total relief.So don't be depressed with your life,as your words in the query indicates.

-My Impression about your health problems-
Dear,after the review of your query facts,Your problem seems to be related with -?Colon Cancer? with adhesive bowel obstruction,causing right back pain with breathlessness and bloated stomach.

-My Reasoning for your health problem assessment-
Though you did not detail the Type of Treatment you are on for Colonic Cancer,with history of old hysterectomy with ovary removal and ? with Gall bladder removal-as indicated from your query,you are prone to have this right back pain with breathlessness with stomach bloating with nausea( could also be from post -gall bladder effect)

Q-1-On your IBS -possibility expected by you after Colonoscopy-examination(IBS, but that doesn't explain constipation or burst of gas with diarrhea, fatique,nausea ?).
Ans-1-I would negate with your expectation,due to the adhesive bowel obstruction with Malabsorption Syndrome related with your multiple gall/ uterus related surgeries in the past.

Q-2- but that doesn't explain constipation or burst of gas with diarrhea, fatique,nausea
Ans-2-This would explain all the complaints you have-like constipation / or / burst of gases with diarrhea/fatigue,nausea?
The partial adhesive obstruction of the bowel causes bloating,breathlessness with nausea
When this partial adhesive obstruction is relieved there is burst of gases with spurious diarrhea of obstructed fecal matter,which is not diarrhea as such,and thus is a Spurious(Fake)diarrhea.

My Final Impression of your health problem-
-Need for Colonoscopy- is planned mostly to see if the colonic growth is causing any Colonic Obstruction and leading to bloated stomach with right back pain in your case.
-With existing health status -possibility of the partial adhesive obstructions from multiple major operations in the past,is the explanation for your Right Back pain with stomach bloatedness.
-The fatigue is due to the Mal-absorption Syndrome from repeated partial adhesive bowel obstructions

So don' worry with the impending planned Colonoscopy.Co-operate with your doctor and things will be fine there after and in time to come.Be positive with the life,which is very NICE.

Hope this reply would help you to get the confidence in your depressed living.
Hope this reply would satisfy to your needs for reasoning of the need for Colonoscopy.

Best of luck for healthy life after Colonoscopy on Tuesday-Tomorrow-

Welcome for any further query in this regard.

Good Day!!
