Hello,

Thank you for the query.

Iron supplementation very often gives black stool. This is a side effect of an iron. And usually it does not indicate blood presence in the stool.

When bleeding has its source in the stomach, stool looks like a tar. Its really black and has strange smell (like digested iron). But such bleeding needs to be really ample to be noticed as a black tarry stool. And for sure your hemoglobin would be much lower.
So most likely your black stools was caused by iron supplementation.

You need to know that bleeding usually does not hurt at all. Its rather a silent thing which can be noticed when pale skin, weakness or black stool appears. So your upper abdominal pain does not indicate that you are bleeding.

Upper abdominal pain can be caused by stomach diseases like peptic ulcer (which in some cases is a bleeding source), stomach inflammation. Stress can also cause stomach or intestines spasm and result with pain.

So gastroscopy is a good idea and should be done as scheduled to rule out stomach diseases.

Your blood work results are almost the same. You need to know that blood cells are floating in the water. If you drink more water, blood work will show less hemoglobin in milliliter. So your results can be different as body hydration were different. For sure such difference does not indicate bleeding.

I assume that your BUN is 5 mmol/L and the ref. ranges are 8-20 mmol/L.
Urea nitrogen is a waste product of proteins. More you eat proteins, higher result you have. So such slightly decreased BUN most does not indicate any disease. It can give an information about your recent protein intake.
If the BUN gets really high, it indicates kidneys disease. But at your case nothing like that is present.

So please do not worry so much. If there is no black stool, weakness, pale skin, vomiting with blood, most likely you are not bleeding. Get your gastroscopy done as it is scheduled. In a meanwhile please avoid coffee, alcohol, fatty foods, spicy foods.

Hope this will help. Feel free to ask further questions.
Regards.

Hi,

Yes, mental state can cause such symptom. Present medicine still does not know much about such diseases. What is certain, brain can control whole body. Nerve fibers are present in every single part of our body.
For example, when you are stressed, stomach acid secretion increases, muscles can shake, sweating appears, nausea can be present, stomach ache etc. It seems that this symptoms are completely needless and its presence has no sense at all. But our brain, for some reason causes such symptoms.
As every person is different, every brain can have different reaction and cause different symptoms. Depression or anxiety can be very serious diseases when not treated. Persons with this diseases very often can not live theirs lives, as it paralyses theirs bodies and minds.

The very extreme example how mind can affect body is catatonia (can be caused by depression). Person with catatonia can have rigid poses (usually very uncomfortable) for many many hours and not react for any external stimuli. Its like muscles spasm for many hours without tiredness, without any control.

So in conclusion, anxiety and depression can do everything with your body.
Its hard to predict about the epilepsy as every person has different reaction to medicines. Some has great response, some do not react for medicines.
And epilepsy is treated with medicines.

I do not assume that you have any mental disorder. Just trying to give you some possible solution.

Hope you will find it helpful.

Shortness of breath and chest tightness very often appear with panic attack or anxiety. More often than other mentioned by you symptoms. Of course there is many others reasons of shortness of breath like asthma, COPD (Chronic obstructive pulmonary disease), heart issues or even pregnancy. But I assume that all this conditions were ruled out with many tests you have had. Spirometry (blow test), chest X-ray, heart stress test should be done when shortness of breath appears.
So maybe if all other diseases were ruled out, you should try to believe that anxiety/depression is causing your symptoms. It is really possible.

Low blood pressure like yours is not a disease if you have such blood pressure all your life. Some people have higher blood pressure, some have lower. You are young person and its really hard to find any other reason of your symptoms. To increase blood pressure you may try drink more sodium XXXXXXX mineral water. Coffee can help with low blood pressure as well.

Hope this will give you some answers.
Regards.

Hi,

So all possible lung and heart condition were ruled out. This means you have no reason to worry about chest issues and breathing issues. You are a very young person and heart or lungs problems are very rare at your age. So no reason to worry at all.

Yes, heartburn (acid reflux disease) can cause chest pain between breasts. It can be a symptom of your stomach issue (same issue can cause your upper middle abdominal pain). That is why gastroscopy which you are scheduled for is a good idea.

Like I have mentioned before, stress causes increased stomach acid secretion. So it all (your anxiety problem and abdominal pain) seems to be connected together.

Your dizziness and inner body trembling are really hard to diagnose symptoms and from my point it seems impossible. So neurologist consult is the best advice I can give you in that matter.

Hope this will help.
