Are you loosing weight?  How much is 75 Kg in pounds?

and how much weight have you lost?

Did you loose it over a short period of time?

I suspect various exposures to chemical such as 2-butoxyethanol or ethylene glycol monobutyl ether, and posting here is a good choice, because I suspect not only civilians, but also MANY military from the past century are harmed by this chemical & it goes unnoticed.  It is frequently in home cleaning products (but undisclosed), and it is in things like gun cleaners / when things explode? ... in jet fuel?  Anyway it is a commonly used pesticide & is used in manufacturing and things like dry cleaning & the making of plastics.  It causes a lot of harm, but is usually overlooked & something else gets the blame (Exposure looks like the flu & a cold or diarrhea can be clues to exposure, too)

Pay attention to when your body 'complains' in these ways.  Is there any cleaning products that are sprayed at your worksite?

I think you are dealing with issues like those with Chronic Fatigue Syndrome (CFS, CFIDS or FM) talk about *

Shortness of breath, and the chills & rapid heartbeat are signs of the anemia this chemical would cause:  AIHA or IMHA ... EGBE Proof of harm is AIHA or IMHA

In this pattern, memory loss as part of the nervous system being attacked by the immune system (Multiple autoimmune issues)

I would wonder about liver damage, either from meds & also from this chemical as it targets liver and kidneys.

I know a man who had similar symptoms and the liver tests seemed OK, but the liver was damaged.  The only way the doctor figured it out was because they took a camera & checked the liver by entering at the naval.

I think it is hard to trust what the numbers are when this chemical is involved, because red blood cells can become immature instead of the right ratio of mature to new red blood cells, and it can mean an adjustment is needed when checking out the 'other' numbers of blood tests.

To find the anemia, doctors must need to check kidney hormones, and the kidney and liver function & to LOOK at the red blood cells.

I don't have any medical background.  I do understand this chemical.  That's all I can contribute. YOU can recognize it, too!

Get a good checklist for Chronic Fatigue Immune Dysfunction Syndrome and see if you don't have a goodly number of the signs for this
