Two groups of unexplained symptoms

[snorkyller]

I'm sick and have two groups of undiagnosed/unexplained symptoms.  

FIRST GROUP:
The below symptoms occurs after each meal and remains for about 1-3 hours.  Thereafter, the symptoms quickly disappears.  I don't know if it starts because my stomach becomes full or because my intestines start to "work".

- Heart beating in strong palpitations.
- Fast acceleration of heart beats when I stand up (or in any easy physical effort).
- Immediate dizziness when I stand up or if I'm upright.
- If I don't remains seated as long as these 3 symptoms are there, my stomach will empty immediately and then I feel like I didn't eat, leading me sometimes to extreme tiredness.

A test recently reveals that my superior mesenteric artery compress a part of the intestines (deodenum I think), and as it is written on the test report, " that could delay the stomach emptying".  Could it be linked with those symptoms? Could the artery (blood flow?) be disturbed by the presence of foods in the compressed area?


SECOND GROUP OF UNDIAGNOSED SYMPTOMS:
I must sleep in a seated position since two years.  If I don't, I feel the below symptoms:

- Heart beating in strong palpitations.
- I constantly wake up with a fast and strong vibration that seems to be produced by my heart and that stops only  if I stand up. (Note: my heart beat is regular).
- I feel like all the blood is going into my head, as if I was upside down, my feet attached to the ceiling.

Thank you very much

this person doesn't say if female/male....If female, doctor, could it be hormones?

Difficult to say without evaluation.

Regarding the palpitations, an echocardiogram can be done to exclude structural causes.  I would also consider a Holter monitor or event monitor to document any arrhythmias.  

If there is concern about delayed gastric emptying, a gastric emptying scan would be the appropriate test to obtain.  If present, there are various medications that can help improve the gastroparesis.

These options can be discussed with your personal physician, or in conjunction with a cardiologist or gastroenterologist.

Followup with your personal physician is essential.
