Question: I have a theory that a TORTUROUS COLON or one that is elongated and or twisted and one that may also contain diverticula can result from consistantly not having access or time for a restroom in which case the person with condition is forced to strain against the urge to defecate sometimes until the end of his work day. If this occured day after day for many years, could this be determined to be the root cause of the malformed colon?
Decided to add some detail for better understanding of the question. There are many occupations which must be done with a daily RACE AGAINST THE CLOCK. These such jobs many times require the employee to work through his lunch and break times and even avoid restroom stops when needed to avoid any delays in the daily schedule which could result in disciplinary action against the employee and sometimes removal in repeated schedule delays.. In my particular case, I am a USPS employee and have worked as a carrier ( on the street ) for about 28 years.

Restrooms are not always available to us. And if any are, it requires a drive to and from the restroom location which can cost on average 15 minutes of delay. Since this is rarely possible to make up that time, Myself, and most likely others, will just resist any urges for restroom usage until ending our tour.

This should better clarify my overall situation and why I have come to ask this particular medical question.
Another symptom I've been having which my intuition tells me is tied to the colon issue, is an extreme sensitivity to sunlight. I notice when the colon complications flare up ( pain, inflammation, obstruction ), the sunlight sensitivity flares up as well. I will discuss the symptoms of this as follows:

As I begin on the street, Things are usually fine with my eyes and vision for the first hour or two. If a bit hazy or overcast, I can usually make it through the entire day. But on very bright days, I will begin to strain very hard against the glare of the sun in order to read addresses. I will later start feeling dizziness, Next symptom will be nausea, sometimes followed by vomiting,, If I continue to stay in the sun, I will next begin to start loosing balance, then become extremely fatigued, and feel as if I will faint, On days the condition goes this far, By the time I'm off work in the evening, I end up going right to bed sometimes with a migraine head ache which may last a couple of days. Along with this I usually cannot eat due to the feelings of nausea. Takes 2 to 3 days of rest to recover when things go this far.

BTW ...I did see eye doctor, had exam, got prescription glasses and sun glasses. But they didn't seem to help much if at all with the sunlight sensitivity issue.
