Blood in stool & ab throbbing

[anonymous203040506070]

I have been experiencing blood in my stool and a slight throbbing in my lower abdomen for about the last six months. This has been going on pretty consistently during this time period. I am 30 years of age and in great health. I am in the military and have a full aviation medical exam every year. (this includes blood work) I drink plenty of water but have a diet low in fiber which I am going to correct tomorrow. I often notice that when I sit on the couch or at a desk and get up I often get light headed or dizzy.

My question is this.  Can this be somthing severe like a stomach aneurysms, ulcer or somthing else? Should I worry? I am hesitant to go to the military doc's because if they find somthing severely wrong I could lose my flight contract. What should I do?

I understand you not wanting to lose your flight contract, as my husband was a pilot until age and health took it away.  He lived to fly, and can identify any plane in the sky merely by the enginne sound.  Your dizziness upon arising from a sitting position can indicate low blood pressure, which a lot of people experience from time to time, usually no big deal.  But the throbbing in your abdomen, along with the bleeding warrants immediate medical attention.  You definitely need to get a colonoscopy, ASAP.  I've had a lot of experience with this and these two symptoms together indicates a problem.  Your health is the most valuable thing, and it is best to head off a problem before it becomes more serious. You won't lose your pilots license, so you can continue to fly.  But you're young with a lot of "flight time" ahead of you.  Take time and do a "flight check" on yourself, the planes will still be there.

Any form of rectal bleeding should form the basis for seeking medical advice.  If you are bleeding continuously even at a low level of blood loss then this could be a cause of dizziness.  Type in rectal bleeding to google/yahoo and look at one of the postings in order to learn more about this complaint - the Medicinenet site is particularly informative.
It is quite possible that the cause of your bleeding has emerged in the annual period following your last (satisfactory) medical examination.  In other words treat this as a new medical complaint on which you should seek prompt medical advice (maybe a colonoscopy)

I blinked and gasped when I read your last paragraph.  You become dizzy when you stand up yet you seem prepared to fly an aeroplane with all the attendant g-forces etc!!  I hope that you are not obliged to fly with passengers/co-pilots because it will be too late to consult your doctor in the event that you crash your plane and then wish to seek medical advice about your dizziness.  Of course I'll withdraw this comment (and the one below) if I have wrongly assumed from your posting that you are a pilot - you may be "ground-based" but I wanted to make these comments to stress the point about seeking medical advice before you embark on certain forms of risk.

I'll re-quote (in modified form) a saying that I directed at another medhelp patient:-

- some people fly aeroplanes when they suffer dizziness and some people jump off the Empire State Building!!
